The DRTE solid state research program is flexible, but has centred on fundamental
electrical and optical effects in elemental semi-conductors or semi-insulating compounds. Magnetic resonance and magneto-resistance in semi-metals have been
investigated, with special attention to properties potentially applicable to generation
of coherent light, or to broad-band microwave or optical modulation.
The Laboratory is equipped for crystal growing and for a wide range of electrical
and magnetic measurements. Optical equipment includes a recording spectrometer
ranging from infra-red to ultra-violet. Cryogenic apparatus permits measurements
down to the temperature of liquid helium.
Because of the recent death of the Section Leader, an experienced researcher
with leadership ability is needed to head the team of four scientists plus technical
staff. It is anticipated that work will expand under the new Head.
QUALIFICATIONS:
Preferably a Ph.D. degree, with several years' experience
and ability to conduct and direct original research.
CITIZENSHIP: Candidates must be Canadian citizens or British subjects.

The Eighth Medal for Achievement
in Physics, 1963
GARNET ALEXANDER WOONTON, B.A., M.A., D.SC.
(Citation read by the President, Prof. G. M. Volkoff)
was born in London, Ontario. There,
also, he received his early education, leading to a B.A. degree from the
University of Western Ontario in Commercial Economics in 1925. He
was then associated with the Bell Telephone Company at Montreal for
a few years, only to recognize that his real interests lay in science rather
than in business. The switch to advanced studies in Physics and Mathematics was accomplished smoothly and quickly—he was awarded an
M.A. in Physics from Western in 1931. This was itself a major achievement and indicated at this early stage in his career one of the great
attributes he has shown ever since: his ability to teach himself large
bodies of fact, laboratory skills, and mathematical techniques, quickly,
surely and independently. Following the M.A. degree, there was no
opportunity for Woonton to continue his formal education, nor was
there any real need: by then he had probably learnt all that professors
can teach. Thus when in 1955, Western accorded him a D.Sc. degree,
they conferred on him honoris causa, an accolade for which in fact his
own labours had qualified him some two decades before.
In the thirties, still at the University of Western Ontario, Woonton
held a joint appointment. As Research Fellow in Physiology he was
concerned with bio-physical problems of the cerebral cortex; as Demonstrator in Physics he did research in electron diffraction. With the
advent of the war in 1939, he became a full-time member of the Department of Physics and joined the team working with the National Research
Council on the development of radar. With this research commitment,
he combined a full teaching program, and it is his proud claim to have
at one time or another taught every field of physics. Clearly recognized
for his versatility in all academic activities and in war research, he now
rapidly advanced through the academic hierarchy, being elected Research
Professor in 1946.

Near the end of this period he became more and more concerned
with the fundamental aspects of electromagnetic radiation, which led
him to important work in microwave optics, notably to studies of the
interaction of electrons in long electron beams and associated noise
problems. He attracted a number of outstanding M.Sc. students, many
of whom were eager to continue towards a Ph.D. with him. When he
was appointed Professor of Physics at McGill University in 1948 he
brought some of them with him so that in no time he established at
McGill an important group involved in many aspects of microwave
electronics. Some of the students of this period were John and Marion
Chapman, Peter Forsyth, George Bekefi, Don Hay, Eric Vogan, George
Harrower, Hugh Hamilton, David Hogg and George McCormick, many
of whom have already had considerable impact on physics in Canada.
Professor David Keys, who had resigned from McGill to go to Chalk
River, had laid the groundwork for the establishment of the Eaton
Electronics Laboratory. Professor Woonton now saw to its realization,
becoming its Director in 1950. The first problems attacked in his new
laboratory were problems of microwave optics. Diffraction by apertures
and obstacles, lens design and aberrations, ionospheric scattering, are
topics representative of the preoccupations of this period. Indicative
too of Woonton's interests then were his contributions to the design of
the Mid-Canada Line and his active participation in 1954 and 1955 in
Project Lamp Light at the Lincoln Laboratory of M.I.T.
But gradually, since the mid-fifties, problems involving the physics of
crystals, of work functions, of paramagnetic resonance and of masers,
start to predominate in the work of the Eaton Laboratory. The flow of
outstanding students has not ebbed, and the number of Ph.D.s from the
laboratory—supervised by Woonton and two or three close associates—
is now thirty.* But beside the students, Woonton has maintained a considerable personal involvement in research, which has come to be
centred on quantum electronics, and includes fundamental problems in
the interactions between spin systems of paramagnetic ions and the
vibrations of the crystal lattice, and in a group of phenomena mostly
associated with the magnetic properties of solids.
Since 1954 Woonton has served McGill as Chairman of the Physics
Department in what has turned out to be a period of innovations:
radical modernizations of the honours and general curricula, and a
considerable and continuing growth of the Department.
Le Professeur Woonton est sans contredit l'une des personnalités les

plus marquantes de la physique canadienne. Il a servi celle-ci, nous l'avons
vu, par ses travaux de recherche, mais aussi en travaillant activement
dans de nombreuses sociétés, tant nationales qu'internationales. En particulier, il fut Président de notre Association en 1948-49, et sa réputation grandissante valut prestige et respect à notre organisation encore
jeune et suspecte en certains milieux. Il fait partie de divers comités
de l'Office des Recherches pour la Défense depuis 1955, et il est éditeur
associé du Journal Canadien de Physique depuis 1957. Sur le plan
international, il fut Président de la Commission VII de l'Union Radio
Scientifique Internationale de 1952 à 1957, et il est depuis ce temps
Vice-Président de cette même Union. Il est également l'un des directeurs
de l'Institute of Electrical and Electronics Engineers auquel il s'intéresse
depuis de nombreuses années.
Ce qui surprend peut-être le plus chez lui est l'énergie énorme qu'il
sait déployer dans tout ce qu'il entreprend, par exemple pour maîtriser
un nouveau secteur de la Physique. Dans d'autres domaines on l'a vu
apprendre à piloter un avion, ce qui l'obligea à quelque chose de peu
facile: diminuer sa masse par un facteur de l'ordre de 1.2. C'est cette
même énergie qui se manifeste maintenant dans son ardeur à apprendre
la langue française. Fort heureusement, il rie se permet pas d'exiger
autant de ses semblables que de lui-même; c'est pourquoi il peut allier
deux qualités qui ne vont pas toujours de pair: une activité débordante
et une cordialité à toute épreuve.
This interest in French is not something recent; for all his southwestern Ontario background, both early and later in his career, Woonton
has been drawn strongly toward Quebec. At McGill he has long
established a record of affection for, and deep interest in, things French.
It may be idle to speculate whether this derives from a forebear who
bore arms on Ile Ste. Hélène to defend Montreal against invasion in
1812, or from others in the Channel Islands with names like LeBreton
or Aubin. But with his characteristic tenacity—with which at an earlier
age he mastered mathematics—he has now mastered French: not
perhaps all the polite conversational gambits, but finesses of grammar
and etymology to confound many an expert. In this turbulent era in
Quebec, it may not be too much to say that among English-speaking
Canadians it is precisely men like Gar Woonton who are needed in
all walks of life to help preserve the amity and unity of the Nation.
Ladies and Gentlemen—I present to you Garnet Alexander Woonton,
a noted lecturer and devoted teacher, a versatile contributor to several
fields of physics and a servant of the cause of physics—in administration,
in the Canadian Association of Physicists and internationally—and last
though not least a delightful human being and advocate of biculturisme\

and in the name of us all I award him the 8th medal of our Association
for achievement in physics. Mesdames et messieurs, j'ai l'honneur de
conférer la médaille de l'Association Canadienne des Physiciens au
professeur Garnet Alexander Woonton.
PROFESSOR W O O N T O N ' S R E P L Y
Mr. President: I would like to thank you, and through you the Canadian
Association of Physicists for choosing me as the eighth recipient of the
Medal for Achievement in Physics. I think that it is apparent to all of
us, that no one ever achieves anything by himself: there is always
behind a University Professor and his work a host of other professors,
colleagues and above all students who have contributed to whatever he
has done. Nor do I want to stop with the scientific part of our lives;
there are always families and there are wives who put up with physicists,
look after them and who see that they are not too much interrupted by
the daily tasks of living. This is our common knowledge and knowing
that you understand this I very gratefully accept this honour which you
have done me.
J'ose m'exprimer ici en français, parce que mes collègues de langue
française sont plus que bilingues. Ils ont montré leur aptitude en linguistiques non pas seulement en sachant le français et l'anglais mais
aussi en apprenant à nous comprendre lorsque nous parlons français.
Je ne crois pas, toutefois, importuner mes collègues de langue anglaise;
mon accent est tel qu'ils ne sauront pas que je ne m'adresse pas à eux
en anglais.
If there are any advantages to being eighteen years older than I was
when C.A.P. was founded, one of them is that I can tell many of you
what happened before you began to take an interest in Physics. Il y a
dix-huit ans, le physicien était un être inconnu au public canadien; les
ingénieurs et les chimistes étaient en demande, non les physiciens.
Durant ces années les physiciens commencèrent a découvrir leur importance dans un univers plus grand que leur laboratoire. Le Radar et
la bombe atomique encore inconnus du public étaient le résultat de
recherches conduites par des physiciens.
Eighteen years ago, nearly all of the physicists of Canada were
concentrated in either Ottawa or Toronto. In Toronto, a crown company had been established, Research Enterprises Limited. Je voudrais
vous entretenir de deux jeunes membres le l'exécutif de cette compagnie.
Ni l'un ni l'autre n'étaient des physiciens dans le sens qu'ils imposèrent à
la profession dans la charte de l'A.C.P. Fred Coombs terminait un cours
en physique à l'Université de Toronto quand il entra dans la R.E.L. et
•

J. J. Brown, un Canadien, venait de terminer un Ph.D. en littérature
anglaise, à l'Université Yale. Coombs rêvait d'une reconnaissance professionelle du genre de celle accordée aux ingénieurs; Brown proclamait
que le progrès suit l'action et non les plaintes. Ensembles, à l'heure du
dîner (aux sandwiches non au vin) ils donnèrent naissance à l'Association Canadienne des Physiciens Professionels.
My close association with C.A.P.P. began in the summer of 1945
when at the invitation of the founders I became Vice-President first under
F. E. Coombs as president, then under the late J. O. Wilhelm. The other
members of the executive were N. J. Abbot, L. H. Turl, A. D. Misener
and Peter Sandiford. J. J. Brown and others were directors. Durant
l'hiver de 1945-46, la jeune organisation traversa de durs moments. Si
vous vous rappelez les procès d'espions canadiens, vous vous souviendrez
que les mots "communisme" et "anti-communisme" flottaient dans l'air.
D arriva qu'une autre organisation, à tendance communiste prenait naissance avec les initiales suffisament semblables à celles de l'A.C.P.P. pour
semer la confusion. Les physiciens non fixés quant aux intentions de
l'A.C.P.P. nous traitèrent souvent commes des personnes atteintes de
la peste.
Il y avait, cependant, dans nos rangs des hommes pleins de courage
et d'idées. L'exemplaire numéro 1 du volume II du Bulletin de l'A.C.P.P.
daté de février 1946 est une preuve de cette avance, car il contient une
liste imposante des membres fondateurs. Laval peut être fier que la
liste contienne les noms de H. F. Feeney, H. P. Koenig, F. Bonenfant,
A. Boivin, C. Geoffrion, G. Hall aussi que de sept membres étudiants.
II est bon de mentionner qu'il y avait dans cette liste plus de membres
étudiants de Laval, que de toutes les autres Universités Canadiennes
combinées.
The first Congress of the Canadian Association of Professional
Physicists was held at the end of May 1946 at the McLennan Physics
Laboratory, the University of Toronto. Je ne saurais m'empêcher de
mentionner deux événements cocasses relatifs à ce Congrès. Le premier
se passa dans les coulisses. Nous avions dépensé quarante piastres (que
nous n'avions pas d'ailleurs) pour annoncer le congrès dans les journaux de Toronto. Ce n'est que plus tard que nous réalisions que dans
les annonces l'endroit où le congrès devait avoir lieu n'était pas mentionné. Le second événement était plus à la vue du public. Un des principaux conférenciers dont la conférence avait été annoncée comme un
événement extraordinaire, était un éminent: physicien. Il oublia de
venir à la reunion.

Murray Hill. Il s'est maintenant retiré du monde des affaires pour profiter des fruits de ses entreprises. Dr. J. J. Brown remporta beaucoup de
succès en combinant une vie d'homme d'affaire et d'étudiant. Ses nombreuses compagnies lui accordent le support nécessaire alors qu'il lance
sa nouvelle aventure, cette fois complètement académique, c'est "The
Institute for Entrepreneurial Research".
Last week, at the same time that I was thinking about the founding of
C.A.P., I was also preparing a report for McGill University on the
future plans of the Ph.D.s and M.Sc.s in Physics who have just received
degrees. Far too many of them are taking positions outside of this
country. This led me to further speculation concerning the number of
B.Sc.s in physics who continue on for graduate work; the best of them
can, and very often do receive very generous awards from graduate
schools outside of Canada and these awards are quite often on a scale
with which we cannot compete. It is difficult to say anything new on this
subject; in fact, was it not at the 1950 Congress in Montreal that C.A.P.
conducted a seminar on this and related topics? I can say, however,
that it seems to me that this situation is no better than it was thirteen
or fourteen years ago and it may be worse. Has not the time come to find
another Brown who will spark another Coombs?
The Departments of Physics in the Canadian Universities appear to
be engaged in a programme of developing the overdeveloped countries.
Let us put it this way: the average Ph.D. attends university for not
less than seven years and each of those years costs somebody not less
than $2,000. Each time a new graduate takes a position across the
border, we make the United States a present of $14,000. How much
return the United States earns on this investment is anybody's guess but
if you count the Canadian physicists in positions of responsibility in
the United States, you can arrive at some kind of estimate. Even the
President has at least one ex-Canadian as an adviser on atomic energy.
I must not pose as an authority nor do I want to talk too long. Let
me say only that in the history of C.A.P. two young men with an idea
succeeded in founding an enduring and important organization in the
face of rather long odds. Again in the face of long odds are there young
men who can solve this problem?
M. le Président, je vous remercie encore de l'honneur que vous m'avez
fait. Je vous remercie tous de votre attention bienveillante.
Some Non-technical Aspects of Science*
G. M. VOLKOFF
E N RÉFLÉCHISSANT au sujet de cette allocution j'ai fait ce qu'un physi-
cien fait très souvent au début d'un nouveau sujet de recherches: j'ai
examiné la littérature du sujet. Dans mon cas la littérature du sujet
se réduit tout simplement à notre journal officiel Physique au Canada.
Je voulais relire ce que mes prédécesseurs ont dit dans de mêmes circonstances. En examinant des allocutions de neuf présidents de notre
association publiées jusqu'ici (je ne trouve aucune mention de ce que
les huit premiers présidents ont dit) j'ai constaté que MM. Herzberg,
Hay, Elliott, Duckworth et Pounder avaient choisi des sujets étroitement
liés à leurs contributions personnelles à notre science si étendue et si
fascinante, tandis que MM. Shrum, Kerwin, Sargent et Currie ont
préféré des sujets de nature plus générale. Ainsi la tradition ne pouvant
me servir de guide j'ai été forcé à faire mon choix indépendamment. Un
tel résultat de l'examen de la littérature n'a, bien entendu, rien de
surprenant.
Within the last few years I have already spoken under C.A.P. auspices
at a number of centres across Canada on that small corner of physics—
the radio frequency spectra of nuclei in crystals—to which my graduate
students and I have made some personal contributions. Therefore, I
have decided not to subject you today to a recapitulation of the same
story, particularly since I have no new exciting chapters to add. Instead,
I wish to speak to you on a more general topic—some lessons taught to
us by science which have wider implications. For an audience of physicists I do not have to describe the personal involvement and satisfactions that the pursuit of science holds for the individual. Neither is it
necessary for me to discuss the social significance of science as the basis
of technology. This aspect of science is so obvious that it is often
held to be the main, if not the sole, influence of science on our civilization. I wish to discuss today some non-technological social aspects of
science which also have a profound bearing on our culture.
The following remarks are based largely on two excellent essays
*A condensation of the C.A.P. Presidential address delivered at the C.A.P.
Annual Meeting at Laval University on June 7, 1963.
12
PHYSICS IN CANADA
which I happened to come across in recent months: "Science and
Human Values" by J. Bronowski,1 and "The Republic of Science" by
M. Polanyi.2 I have derived much pleasure and profit from reading these
two articles, and I shall consider my talk today as having attained its
objective if it leads some of you to read these two essays in detail for
yourselves.
First, I want to put before you Bronowski's contention that, contrary to a widely held belief, the pursuit of science is far from being
a neutral or a mechanical activity unrelated to the problem of values.
He finds that "like the other creative activities which grew from the
Renaissance, science has humanized our values. Men have asked for
freedom, justice and respect precisely as the scientific spirit has spread
among them."
I then want to discuss Polanyi's point of view that "in the free cooperation of independent scientists we shall find a highly simplified model of
a free society." Since physicists thrive on models, you will be interested,
I am sure, to examine the lesson for the political and economic theory
of society as a whole which Polanyi draws from his investigation of
his model Republic of Science.
Bronowski's aim is "to show that the parts of civilization make a
whole" and, in particular, he wants to clarify "the place of science
in the canons of conduct which it has still to perfect." He advances three
main theses.
1. Creative activity is basically the same in the sciences and in the
arts.
2. If there is any difference between the two fields, it is that the
sanction of experienced fact imposes an exact boundary which
encloses the scientist in a way in which it does not constrain the
poet or the painter. The scientist's need to test his concepts continually against experience imposes what Bronowski calls the
"habit of truth" upon him, and through him on our whole civilization.
3. A study of the conditions for the success of science uncovers in them
"the values of man which science would have had to invent afresh
if man had not otherwise known them : the values which make up
The Sense of Human Dignity."
For lack of time I shall not develop any further Bronowski's first
thesis on the universality of the creative process.
In developing his second thesis on the "Habit of Truth" Bronowski
stresses the role played in the scientific method by concepts, even though
he fully realizes that this view is not shared by everyone, and in particular not by the empiricist and the operationalist schools of philosophy.
NON-TECHNICAL ASPECTS OF SCIENCE
13
Bronowski formulates the following familiar sequence as characteristic of science: observation of appearances, organization of these into
laws, creation of concepts based on these laws and the testing, and, if
necessary, correction, of these concepts by observing predicted behaviour
in other experiences.
I shall here, for a selfish reason which will soon become apparent,
digress for a while from Bronowski's main line of argument. It is not
given to many scientists to introduce entirely new concepts. These are
the Newtons, the Einsteins, the Plancks, the Bohrs and the Heisenbergs.
Most of us have to be content to be the hewers of wood and the drawers
of water, and to spend our working days busily and happily either testing
the consequences implied by some current concept (always in the hope
that a contradiction will emerge requiring a modification or a refinement
of the concept), or collecting reliable data which might later be organized
by someone, not necessarily ourselves, into new patterns of order, leading
to new laws, and perhaps eventually to new concepts.
It is in this workaday world of the scientist that another small difference between the arts and the sciences crops up which, nevertheless,
is a source of gratification to the human vanity of even a run-of-the-mill
scientist.
In the frescoes of a Rafael or a Ghirlanclaio the world pays tribute
to the creator of the overall concept and of the grand design of the
masterpiece, but no attempt is made to apportion individual credit
to the many now nameless apprentices in the master's studio who have
contributed a skillfully draped garment here, a chubby cherub there,
to the overall design blocked out in bold but rough outline by the
master painter.
Science is a much more cumulative and step-by-step activity in
which even a minor contributor stands a fair chance of having his name
linked to his small share in the total enterprise. To use a personal
example, and now you see why I have taken this detour, the so-called
Volkoff method of extracting from observed resonance frequencies the
components of the tensor describing the coupling of nuclear electric
quadrupole moments to the electric field gradient in crystals lacking
axial symmetry is a very straightforward and unsophisticated application
of elementary Fourier analysis and diagonalization of matrices. It could
have been, and surely would have been, developed by any other physicist faced for the first time with the same problem. Yet, I will not deny
that it gave me pleasure to see this minor bit of technique linked with
my name in a standard review article3 and in a comprehensive monograph on the subject.4
I hasten to add that this technique has so far contributed only to the
14
PHYSICS IN CANADA
verification, and not to any modification of the underlying concepts.
Nevertheless, it is a minor manifestation of the habit of testing and
correcting the concept by its consequences in experience which (according to Bronowski) has been the spring within the movement of our
civilization since the Renaissance.
We now return to Bronowski's third and main thesis: the impact of
science on human values.
Condensed to barest outline (and omitting most of the numerous
quotations included in the oral presentation; the reader is referred to
Bronowski's original article for these) his argument runs as follows.
If the truth of a concept is to be tested in action then certain prerequisites follow: independence in observation, and then in thought.
As a result science has bred the love of originality as a mark of independence. Originality means dissent, but this is not an end in itself.
Dissent is to freedom, as originality is to independence of mind: one a
mark of the other. Independence must be protected if science is to
become effective as a public practice. This leads to the need of free
inquiry, free speech, free thought, tolerance.
"The society of scientists must be a democracy. It can keep alive and
grow only by a constant tension between dissent and respect, between
independence from the views of others and tolerance for them."
Since "science confronts the work of one man with that of another
and grafts each on each . . . it cannot survive without justice and
honour and respect between man and man."
"Science is not a mechanism but a human progress. Human search
and research is a learning by steps of which none is final, and the
mistakes of one generation are rungs in the ladder, no less than their
correction by the next."
Here I will indulge in another personal note to illustrate two of
Bronowski's points which I have just related: dissent as a necessary
component of scientific progress, and the inevitability of human error,
which together with its correction can still serve as a rung in the ladder.
My very first independent scientific publication5 as a graduate
student working under Professor Oppenheimer's direction in 1939 arose
from my questioning Schwarzschild's long accepted statement that there
exists a natural general relativistic limit to the mass of a sphere of
matter of constant density. I pointed out that this limit exists only if the
pressure at the centre is required to remain finite. However, in attempting to investigate the behaviour of massive spheres of constant density
when the pressure was allowed to become infinite at the centre I made
the rash statement that the differential equation which I set up could not
NON-TECHNICAL ASPECTS OF SCIENCE
15
be integrated exactly, and attempted to treat the problem numerically
(and as it turned out later, not too successfully). Ten years later Prof.
Max Wyman8 pointed out that my inability to solve my equation
exactly was entirely due to my failure to recognize it as a form of the
Riccati equation (apparently "well-known" to mathematicians, but not
to myself). He then proceeded to give a rigorous discussion of the
properties of what he, nevertheless, generously named "Volkoff's
Massive Spheres" which now remain under that name in the literature
as a permanent extension of Schwarzschild's work.
This personal incident was quoted as an illustration of Bronowski's
words: "This is why the values of science turn out to be recognizably
the human values: because scientists must be men, must be fallible, and
yet as men must be willing and as a society must be organized to correct
their errors. William Blake said that 'to be an Error and to be Cast
out is a part of God's design'. It is certainly part of the design of
science."
"The society of scientists has to solve the problem of every society,
which is to find a compromise between man and men. It must encourage
the single scientist to be independent, and the body of scientists to be
tolerant. From these basic conditions, which form the prime values
there follows step by step the spectrum of values: dissent, freedom of
thought and speech, justice, honor, human dignity and self-respect."
This completes the argument in support of Bronowski's thesis, which
is one of the two main points of this talk, that "if these values did not
exist, then the society of scientists would have to invent them to make
the practice of science possible." Science is not morally neutral.
The remainder of this address as presented orally (and abbreviated
considerably here to conserve space) consisted of recounting in some
detail and acompanied by copious quotations (for which the reader is
referred to the original article2) Polanyi's contention that scientists
form a society the modus operandi of which has valuable lessons for
free society as a whole.
Scientists choose their problems freely, and pursue them independently, but, nevertheless, operate as members of a closely-knit organization. Their activities are coordinated by the continual adjustment of the
efforts of each to the hitherto achieved results of the others. This leads
to a joint result unpremeditated by any of those who bring it about,
and which will be the best possible if each consecutive step is decided
upon by the person most competent to do so.
In discussing the method whereby this mutual adjustment takes
place Polanyi brings out the same tension between forces of conformity
16
PHYSICS IN CANADA
and dissent which was already noted in connection with Bronowski's
article, and both authors demonstrate that such tension is not inconsistent with stability of the society of scientists.
Polanyi then discusses the role played by tradition in science, and
notes that it upholds a dynamic authority which cultivates originality,
and whose continued existence depends on its constant self-renewal
through the originality of its followers. In this he sees a valuable lesson
for free society as a whole.
"A free society may be seen to be bent in its entirety on exploring selfimprovement—every kind of self-improvement. This suggests a generalization of the principles governing the Republic of Science. It appears
that a society bent on discovery must advance by supporting independent
initiatives, coordinating themselves mutually to each other. Such adjustment may include rivalries and opposing responses which, in society as
a whole, will be far more frequent than they are within science. Even
so, all these independent initiatives must accept for their guidance a traditional authority, enforcing its own self-renewal by cultivating originality
among its followers.
This view transcends the conflict between Edmund Burke and Tom
Paine. It rejects Paine's demand for the absolute self-determination of
each generation, but does so for the sake of its own ideal of unlimited
human and social improvement. It accepts Burke's thesis that freedom
must be rooted in tradition, but transposes it into a system cultivating
radical progress. It rejects the dream of a society in which all will labour
for a common purpose, determined by the will of the people. For in the
pursuit of excellence it offers no part to the popular will and accepts
instead a condition of society in which the public interest is known
only fragmentarily and is left to be achieved as the outcome of individual
initiatives aiming at fragmentary problems."
For an elaboration of this point of view the reader is urged to consult
the original article.
I have only one duty left to perform. I have been speaking to you
of the role played by tradition in a society of scientists. I must, therefore,
remind you that two years ago President Duckworth inaugurated what
he hoped might become the tradition of a Presidential Poem. He thereby
threw out a challenge to his successors. Last year President Pounder
chose to exercise the scientist's sacred prerogative of dissent from tradition. I choose to conform, and accept the challenge. For the theme of
my poem I choose the technical subject which I now realize I should have
chosen for this whole talk in place of the rambling general discourse
which you have just heard. And since this whole Presidential address
has been derived from other sources, so, for better or verse7, also is the
NON-TECHNICAL ASPECTS OF SCIENCE
17
Presidential Poem whose title has been inspired by our last night's
delightful program of songs.
SONGS O F AN A T O M I C N U C L E U S
Sing a song of magnets,
A crystal full of spins,
When the nuclei relax
Then the fun begins.
With the r.f. tickling them,

Mais, quel dommage qu'il n'y a plus de temps
Pour écouter leur belle chanson.

Profile: Leon Katz
30 YEARS AGO there appeared in the corridors of the old Physics
Building at Queen's University a graduate student whom very few of
the final year and other graduate students knew from undergraduate
days. Many never did get to know him because his time was obviously
carefully organized and rigorously controlled. With some, this would
have meant that life was real, life was earnest—and dull. With Leon
Katz life was never dull, was also fun and he was a welcome visitor in
the labs of the other graduate students. His intellectual curiosity and
his enthusiasm for physics, both his and theirs, were infectious and
stimulating.
Leon Katz, born in Poland in 1909, came to Toronto at an early age
and secured his primary and secondary school education there. After
high school he found work in Kingston at the Monarch Battery Works
where he put in a full day's work at research and development in between
attending classes in Engineering Physics at Queen's University, from
which he graduated in 1934. After graduation he returned to the
Monarch Battery Works as plant foreman and continued there until
1936. Just as a side line, in 1935 he helped as an active campaigner to
get the late Norman McLeod Rogers elected to Parliament. He came
back to Queen's as a graduate student under the late Dean A. L. Clarke
to work on a resonance method for determining the ratio of the specific
heats of gases. Katz developed a crude oscillating piston device into an
extraordinarily elegant, high-precision piece of apparatus. His Master's
thesis was certainly the equal of many a Ph.D. thesis and it won him
scholarship recognition at more than one post-graduate school. He chose
to go to the California Institute of Technology which he attended from
1939 to 1941 and from which he received the degree, Doctor of
Philosophy cum laude. He worked under C. D. Anderson on the construction of a two-foot cloud chamber and on cosmic ray distribution
at sea level.
After graduation he went to the Westinghouse Electric and Manufacturing Co. in Pittsburgh as resident engineer in their electronics and
electromechanical division. His work there with proximity fuses and
his propensity for getting a little fun out of life made him one of the
ALMOST
LEON KATZ
19
fathers of the radar speed trap used so effectively by law enforcement
officers all over the continent. He observed that passing cars gave him
a marked Doppler effect when he pointed his transmitter out of the
laboratory window at the traffic on a nearby highway. Leon took quite
a ribbing from fellow physicists years later at a luncheon meeting at
which he told how he had explained as an expert to the great satisfaction
of the magistrate and the even greater embarrassment of the speeding
motorist in a Saskatchewan police court how the device worked. His
fellow physicists had apparently been on the wrong end of police radar
development!
In 1946 Katz went to the University of Saskatchewan to "look after"
the newly acquired Betatron. His work there has been a credit to him
and an honour to Canada. Other betatrons may have been something
of white elephants but not that at Saskatchewan and the work which
Katz and his associates have done has received world-wide recognition.
With these accomplishments as basis and guarantee of the future, who
could refuse to listen to his proposition for an even better accelerator?
Those of us who talked to Katz in Quebec this past June know that this
dream has now been translated into reinforced concrete underground
chambers and beam paths. The rest of the gear follows!
In 1941, in Pasadena, California, Leon Katz married Miss Georgina
Caverly of Kingston. They have four children, three boys and a girl.
Taking care of their needs, as well as Leon's, has kept Georgina from
more than casual and very occasional return to the journalistic career
she followed before marriage. Her intense interest in his career is well
revealed by an incident arising out of the preparation of this note. I
wired Leon two questions on early work. Georgina replied as follows:
"Leon in Moscow. Answers are. . . ." And they were what I wanted!
Many honours and awards have come to Katz. He was the only
Canadian invited to the All Union Conference of the Academy of
Sciences of the USSR in November, 1957 and was one of the Canadian delegates to the Second International Conference on the Peaceful
Uses of Atomic Energy. He has served as secretary of the sub-committee
on Nuclear Constants at the American Academy of Science—National
Research Council, and is past president of Canadian Friends of Hebrew
University, Saskatoon Branch. He is a member of Sigma Xi, and the
Physical Society (British), a Fellow of the Royal Society of Canada and
of the American Physical Society, a long time member of C.A.P. and
more than once a member of its Executive Committee. He has served
C.A.P. in special capacities, being a member of its committee to report
on the feasibility of a high energy machine for Canada, and chairman of
its committee to acquire a high energy machine for Canada. His published
PHYSICS IN CANADA
20
papers cover work in the fields of thermodynamics, microwave spectroscopy and nuclear research. C.A.P. can be thankful that Katz was one of
the more than three and a quarter million Canadians who went south of
the border in search of higher education but was one of the few who
returned to do great things in physics in Canada. He'll be good for
C.A.P. as its new President.

C.A.P. Affairs: The 1963 Congress
T H E ANNUAL M E E T I N G , Q U E B E C , J U N E 7 T H , 1 9 6 3
THE FOLLOWING MATERIAL
has been condensed from the Minutes of the
Annual Business Meeting.
PRESIDENT'S R E P O R T F R O M COUNCIL
Standing Committees
Certain regular activities of the Association have been continued by
our standing committees. The Awards Committee, under the chairmanship of Dr. Larkin Kerwin, has made a selection, and the C.A.P. Medal
will be presented this evening at the banquet. Dr. J. H. Blackwell, for
the Prize Committee, will report this evening on the winners of the
prize competition for undergraduates. The Secondary School Science
Committee has, as you know, been gradually extending the scope of its
school competitions. This year competitions were held in nine provinces,
and later in the course of this meeting the names of the first place winners
will be announced. A complete list will be published in Physics in
Canada. The Association provided $ 3 , 0 0 0 for prizes for these
competitions.
Dr. W. N. English's committee on lecture tours arranged for seven
lecturers who gave C.A.P. lectures in twenty-five different institutions.
Professor John Robson constituted a committee of one to carry on the
new venture introduced last year to bring in Distinguished Visiting
Physicists. Dr. Luis Alvarez visited two Western Universities to redeem
his promise of a return visit, when illness caused him to cancel last year's
tour, and Dr. Norman Ramsey visited two Eastern Universities.
Subject Divisions
The subject divisions of Medical and Theoretical Physics continue to
be active. A new subject division of Earth Sciences has been formed.
Committee on Industrial Physics
A report by the Committee on Industrial Physics has been published
in the most recent issue of Physics in Canada. Another 1 0 , 0 0 0 word
22
PHYSICS IN CANADA
report has been submitted to the Executive, and investigations are in
progress whether it can be published in part or in full.
Physics in Canada
The Editor of Physics in Canada, Dr. D. M. Hunten, unfortunately
has had to resign due to a change of location. I invite the members to
express their appreciation of his excellent services in this timeconsuming and onerous position. A successor will be appointed by the
joint Council Meeting tomorrow.
Miscellaneous
A 1962 membership list has been distributed.
A revised edition of the pamphlet "Careers in Physics" to be published both in French and English is in preparation.
The possibility of allowing members to substitute as part of their
membership privileges subscription to some other journal as an alternative to the Canadian Journal of Physics is being investigated. The proposed new journal in Earth Sciences to be published as one of the
N.R.C. journals, is one such possibility.
C.A .P. Educational Trust Fund
Promotional literature has been prepared by Dr. Hay and after
approval by the Executive, is now being printed. Distribution to a large
list of potential donors will be followed up by personal visits from
C.A.P. members. As will be seen from the Treasurer's report at the
present time the Fund has been nearly exhausted. No corporate members have been recruited as yet.
Future Congresses
The Royal Society of Canada has announced that its 1964 meeting
will be held in Charlottetown, P.E.I., and its 1965 meeting in Vancouver,
B.C.
Limited housing facilities in Charlottetown prevent an invitation
being issued to all the learned societies. The C.A.P. has received invitations from the neighbour institutions of Dalhousie in Halifax, N.S. and
U.N.B. in Fredericton.
After some consideration the Executive has accepted the invitation to
hold the 1964 C.A.P. Annual Congress at Dalhousie University in Halifax, N.S.
A straw vote expression of opinion of this meeting will be useful with
respect to the desirability of following the Royal Society to Vancouver
in 1965. (A majority of those present voted in favour of a B.C. Congress
in 1965.)
C.A.P. AFFAIRS

OTHER BUSINESS
The Treasurer's Report showed a revenue of $12,027.00 and expenses
of $9,445.00 for the year ending April 30; cash in hand was $8,800.00.
In addition, the High Energy Study Fund contained $240.00 and the
Educational Trust Fund $260.00.
The Registrar's Report gave the following membership as of April
30th: members, 588; associates, 359; students, 397; members without
fees, 9; total, 1353. Twenty-eight members, twenty-nine associates and
123 students had not yet paid their fees. There were 7 active student
chapters representing a gain of 2 and a loss of 3 chapters in comparison
with 1962.
A report of the High Energy Committee was accepted including three
recommendations that steps should be taken to acquaint Canadian academic and governmental circles with the comparative weakness of the
Canadian program in this field.
A motion was passed authorizing the initiation of a study of the
demand of research physicists in Canada over the next ten years. This
motion was proposed by Dr. Robson and seconded by Dr. Dugdale.
The new officers and counselors were declared elected and the new
President, Dr. Volkoff, took over. [The names of the executives and
council appear at the end of this section.]
O N T A R I O E L E C T O R A L DISTRICTS
The following electoral districts in Ontario were set up at the meeting.
(i) Eastern Ontario; east of 78° W longitude
(ii) South-western Ontario; west of 80° W longitude and south of
Georgian Bay or south of 43.5° N latitude
(iii) Central and Northern Ontario; the remainder
C . A . P . P R I Z E EXAMINATION
The Examining Committee for 1962-1963 was J. H. Blackwell
(chairman), R. E. Bell and I. K. MacKenzie.
All public operations of the Committee were carried out bilingually.
The organization of the examination began in October and the examination was made final in February. On the 19th January the Heads of the
Physics Departments of the 33 universities approached in 1962 were
notified of the 1963 examination and asked to submit estimates of their
probable number of candidates by the 15th February. Twenty-five replies
were received, in some cases only after reminders had been sent.

PHYSICS IN CANADA
The examination papers were mailed late in February and the examination was held on Tuesday, March 5th.
Fifty-seven candidates from 17 universities wrote the examination.
The marking of the papers and double-checking of the top candidates
was not completed until early May. This was not due entirely to the
slowness of the Chairman, but in part, at least, was due to the very
close original ranking of the 2nd to 9th candidates. This necessitated
even closer checking than usual and conferring amongst examiners. In
the end it was decided to amalgamate the second and third prize money
and distribute the sum in five equal parts to candidates Nos. 2-6 who
were rated as second-equal for all official purposes.
The results in the form of a ranked list without marks were circulated
to the heads of the Departments of Physics and some officers of the
Association, and the six winners were notified. They were:
( 1 ) A. B. Langdon
(2) R. Birgenau

Comment should be made on the exceptionally good performance of
Mr. Langdon who led his nearest rivals by 16 per cent. Despite the
difficulty with the candidates immediately following Mr. Langdon, the
spread in marks was quite large but it was noticeable that there were a
half-dozen or more candidates whose scores were so low that it is
doubtful whether they should have been encouraged to enter.
The present chairman would like to acknowledge his indebtedness
to previous chairmen and in particular to the Chairman for 1962, Professor R. E. Bell, for the excellent administrative procedure set up. By
following the 1962 system the work of organizing the examination was
made very easy.
In conclusion the Chairman would like to thank both Professor Bell
and Professor MacKenzie for their hard work, their cooperation and
their tolerance of the Chairman's failings:

DISCOVERY OF DELAYED PROTON EMISSION
IN THE 1963 Congress Issue of Physics in Canada (vol. 19, no. 3), there
appear two abstracts of reports given in Quebec by R. Barton and R.
McPherson of the McGill Radiation Laboratory, on the subject of
delayed proton emission. They describe some of the first work to be
done with the McGill cyclotron's regeneratively extracted beam before
building expansion required shutdown for much of 1963. This work
resulted in the discovery of the first "new" type of radioactivity in
over 20 years. In 1939, Roberts and others at Chicago discovered delayed neutron emission in fission products, and in 1940, Petrzhak and
Flerov in Russia discovered spontaneous fission of uranium. In 196263, Barton and McPherson bombarded aluminum and silicon targets
with 97 MeV protons and discovered delayed proton emission, which
is closely analogous to delayed neutron emission. In the decay process, a proton-rich nucleus, Si25, emits positrons with a half life of about
0.3 seconds, producing excited states in Al 25 that are proton-unstable.
Protons are then emitted with discrete energies between 2 and 5 MeV,
leaving behind the highly stable nucleus Mg24. Other delayed-proton
emitters are Mg21, Ne17, and O 13 .
A complete report of this work has been accepted for publication
in the Canadian Journal of Physics. The experiments will resume when
the cyclotron beam is again available.

Dr. Morrel P. Bachynski, Director of the Microwave and Plasma
Physics Laboratory, was honoured by the Radio Corporation of America
with its highest technical accolade, the David Sarnoff Outstanding
Achievement Award n Engineering, for his outstanding contribution
and leadership in his chosen field. The award was presented in New
York on May 24, 1963, comprising a gold medal, a citation, and a
cheque for $1000. The David Sarnoff Outstanding Achievement Awards
were established by RCA in 1956 to commemorate the fiftieth anniversary in radio of General David Sarnoff. Two awards to individuals
have been made annually since that time to one scientist and one
engineer within the Corporation.
Dr. G. G. Cloutier of the plasma physics group gave a series of
invited lectures in the University of California, Los Angeles, summer
course on Magnetofluid and Plasma Dynamics (June 17-28, 1963),

A.I.A.A. Fifth Biennial Gas Dynamics Symposium at Northwestern
University, Evanston, Illinois, on August 16, 1963. Dr. R. W. Jackson
gave an invited paper on "Semiconductor Beta and Gamma Detectors"
to the Summer Meeting of the I.E.E.E. in June.
As a result of the success of the telemetry transmitter designed and
built by RCA Victor for the Alouette satellite, the advanced devices
application group of the Research Laboratories have supplied telemetry
transmitters for the NASA satellites "Topsi" and "MMC" (micrometeoroid measurements capsule) and are being kept busy with an
increasing number of projects of the same nature.

N E W S F R O M THE UNIVERSITY OF W A T E R L O O
With the aid of government and University grants the Department
has obtained a Collins Liquefier. This will give a boost to the solid state
and low temperature experiments which have been awaiting its arrival.
The physics of thin metallic films is going ahead as Dr. Boswell has
obtained an electron microscope through N.R.C. and University grants.
In keeping with the trend towards greater application of physics in
industry, the Department has introduced a new co-operative Honours
Applied Physics programme leading to an Honours B.Sc. degree. The
first students will register this fall and as in the co-operative Engineering
programme, students will spend alternate terms in University and industry. The Mathematics and Physics content of the course is the same as
that of the regular Honours Physics course, but there is an extended
choice of electives in Science and Engineering subjects.
An "expedition" to view the solar eclipse of July 20, 1963, was
organized by Dr. G. E. Reesor. Members from all faculties of the University journeyed by special train to Moose River, about 50 miles south
of Moosonee, Ontario. None were professional astronomers and the
intention was to take photographs and record light intensity and temperature during the eclipse.

George Neilson Whyte
13, 1963, George Neilson Whyte died in Ottawa
after a six-month illness. Late in his 39th year, he had recently been
promoted to Professor of Physics at Queen's University, Kingston and
was at the peak of his career.
Neil Whyte was a keen observer of the world in which he found
himself. Quick to uncover hypocrisy and humbug, he was no cynic,
but enjoyed both the people and the things around him. Indeed, few
have come to better terms with their environment, both human and
natural. He loved his native city of Ottawa, loved to walk in it, photograph it, watch it change and grow. No less did he love his University,
Queen's, where first he went as a student in 1942. When he graduated
four years later he led his class in Applied Science, was awarded the
Medal in Physics, the Governor-General's Medal and a Shell Oil
Graduate Fellowship. The following year he obtained an M.Sc. under
the direction of Professor J. A. Gray.
In May of 1947 he left for Princeton where the next four years were
equally successful. He was awarded a Procter Fellowship, the most
coveted fellowship bestowed in Physics, and went on to do a thesis on
Cosmic Rays, working with Professor George T. Reynolds. In order to
obtain burst data near the geomagnetic equator, he spent a summer
in the Pacific flying balloons from the deck of the USS Norton Sound.
After obtaining an A.M. and a Ph.D. from Princeton, he remained there
as an instructor for another year before joining the staff of the National
Research Council of Canada in 1951.
There, working with the X-rays and Nuclear Radiations Section of
the Applied Physics Division, he soon became interested in the physics
of radiation dosimetry. In conjunction with his colleagues at N.R.C. he
made extensive contributions to the field in a long series of papers
written in the years 1951-58. This work brought him an enviable
international reputation which was further enhanced with the publication
in 1959 of his book "The Principles of Radiation Dosimetry".
Successful though he was in this phase of his career, a lifelong interest
in teaching, which had been stimulated anew by a year at Queen's in
1956-57, led him to return there permanently as an Associate Professor

PHYSICS IN CANADA
in 1958. At Queen's he was able to continue his contributions to dosimetry through his membership in the committees of the International
Commission on Radiological Units and Measurements and of the U.S.
National Committee on Radiation Protection and Measurements. Nevertheless, his main interest from now on was to be in the teaching of
physics, a pursuit for which he was admirably fitted. At the time of his
death he was engaged in writing a textbook on the laboratory teaching of
Nuclear Physics.
Neil Whyte was quiet and unassuming by nature, so that few, even
of his close friends, knew of the totality of his accomplishments; precise
and logical by training, few ever caught him with an irrational or inconsistent point of view. Just as he valued his own privacy, so he respected
that of others. Yet he was no recluse. Remembering the distraction
caused by otherwise insignificant mannerisms of his own teachers, he
once staggered his students at Queen's by having them fill in a questionnaire, which among other things, asked them to fist any of his irritating
mannerisms, or other deficiencies in his presentation.
He took a keen interest in the cultural and political life of Canada
and it was always a pleasure to discuss these things with him. At such
times, his calm outlook, natural insight and kindly sense of humor shone
through vividly, and it was a rare occasion when one's own ideas were
not clarified. In recent years his principal hobby was photography. It
was characteristic of Neil, though not of amateur photographers in
general, that his rare showings of transparencies always left his viewers
hoping for more. It is possible that he never took any bad shots, but it is
a good deal more likely that the mediocre ones were ruthlessly weeded
out.
If it is ever possible to sum up a person in one word, that word for
Neil Whyte would probably be consideration. At no time was this consideration for others more evident than during his final unsuccessful
battle with a brain cancer. His too early death is a grievous loss to his
family, his friends, to Queen's and to Canada.

Letters to the Editor
Dear Sir:
In the Spring issue of "Physics in Canada" Capius declared that the physicist
as such is not a "measurer" but that "this lowly distinction belongs, of course, to
the engineer. The true physicist 'measures' only as a means to an end". These
two sentences are too clear to be merely bad phrasings. They are the deliberate
expression of misinformed and bigoted ideas. It seems to me that it is evident
that no one, be he engineer, tailor or bookmaker measures just for the pleasure
of it. Paragraphs could be written tearing apart the bizarre ideas of the above
mentioned gentleman, but the constructive thing to do is to take the positive
approach and explain what the engineer is.
The engineer must have a discipline that is not required of the man engaged in
pure scientific research. He cannot content himself with the probing of nature
and the accepting of whatever he finds. He must confine himself to the specific
problem at hand and must build a practical solution taking into account such
factors as time, cost, and provision for future modification.
An engineer cannot be content with being qualified only in the technical sense.
He must also be adept at the organization of a task and the "man management"
of others also responsible in some way for its accomplishment. An engineer able
to design but not able to supervise installation and servicing would be of limited
use.
The physicist has not the same public responsibility as the engineer. Much is
made of the responsibility of the medical profession (which is great) however
one must admit that the doctor's mistake will usually affect but one person at a
time. A mistake on the part of the engineer will have much farther reaching
consequences as is witnessed by the Quebec Bridge disasters and the burst dam
in southern France two years ago, as well as by the crashes of the first Comet
jetliners. The engineer, perhaps more than any other member of our society,
holds lives in his hands.
The engineer, then, is a man of many hats. As well as being a man of science,
he must be a businessman, an efficiency expert, a cost accountant, sometimes
a salesman and often a diplomat.
The engineers among the members of the C.A.P. were no doubt hurt, as I was,
by the unthinking remarks of the physicist in the spring issue. It is to be hoped
that these few paragraphs will contribute to a better understanding that will lead
to what can only be a fruitful partnership.

Dear Sir:
Reading the article "Applied Physics" by Dr. Howlett in the Spring issue of
P.I.C. I found myself agreeing with everything he said, except what he said
about what I said. I believe some of the differences are only apparent, and arise
44
PHYSICS IN CANADA
only from differences in the definitions of terms between us. Perhaps I may be
allowed a few words to try to clarify what I was trying to say.
To categorize the RCA Victor Research Laboratories simply as a research-forprofit contracting outfit is convenient (and true in some measure) but to do so
is to miss a major point of my essay. This was, that during those years contracting was the only way a Canadian electronics company was able to afford
research. The basic aim of the research group—to contribute eventually to new
and improved company products—was inevitably warped somewhat by contract
terms, but was always there. Over the past year and a half, with the government
research assistance programs, conditions have been changing everywhere for the
better and, to the extent that contract seeking becomes unnecessary, the assistance
programs can be judged to succeed. I agree with Dr. Howlett that defence contracting as a basis for applied research leading to new commercial products is
not the most efficacious or most economic means—measured in terms of output
per year, output per dollar, or output per scientist or engineer.
I still stand by my remark that a company management will be disappointed if
it attempts to judge the value of its scientific research group solely, or even
primarily, by what new products it has invented, shocking as it may seem. But
it must be taken in the context of the size of company I am talking about, and
my definition of "research", to be understood. The real determinant of a company's
effectiveness in introducing new products is its development organization and,
secondarily, its marketing organization. In development is also where the major
part of the cost is. (I have an idea that Dr. Howlett has included "Development"
in his definition of "applied physics".) The point is that ideas are everywhere.
We can't keep up with them. The present rate of growth of science and technology is such that the role of the industrial scientific research group is becoming
more a role of processing new information—of understanding it, interpreting it,
channelling it to the needs at hand (in, of course, an enlightened and original
way)—more than strictly inventing. To clarify the relation between the different
levels of scientific and engineering effort in an industrial research and development organization would require much more space than I can be allowed here,
but I hope that I can accomplish it before long to my own and everyone else's
satisfaction.
The impressive record of the Applied Physics Division of the NRC in generating
ideas which have been exploited into new commercial products seems to belie
what I just said above. But it must be remembered that the situation in which
you invent something, and then search the world until you find a sponsor to
exploit it, differs in an essential respect from the usual industrial research situation.
The research laboratory of the individual industry is almost the inverse case.

BENJAMIN INC. has done a real service to physics through its paperback editions
of lecture notes and reprint collections. While disappointments like Feynman's
Quantum Electrodynamics have occurred in its Frontiers in Physics series, real
excellence has also been achieved in books such as Quantum Statistical Mechanics
by Kadanoff and Baym. Benjamin has used paperback binding and photo-offset
printing in an attempt to keep costs down and to speed up publication of topical
material. To a considerable extent this purpose has been achieved. Still $9.75 for
the Bergen lectures seems like a lot of money for a paperback, whatever its
contents.
The theory of many-body systems has undergone a very extensive development
during the past decade and some notable results have been achieved. In particular, conventional perturbation theory has been subjected to a good deal of critical
analysis, and important modifications have been introduced to make it applicable
to a wide variety of many-body problems, e.g. to problems in transport theory
and statistical mechanics. In this development, the language of second quantization
has proved invaluable and a number of important techniques have been borrowed
from the theory of quantized fields. Even in the striking case of superconductivity,
where conventional perturbation theory breaks down entirely, the language of
second quantization has proven the natural language of description. The modern
literature in low temperature and solid state physics, and to some extent in
nuclear physics, employs this language so extensively that no serious student in
these fields can profitably avoid exposure to it.
From this point of view, the Bergen lecture notes are certainly useful. The 35
page introduction to the N-Body Problem by Falkoff makes the subject accessible,
at least superficially, to any student of modest talent who has a good background
in conventional quantum mechanics. Falkoff's introduction is followed by a very
clear and concise account of the BCS theory of superconductivity by L. N.
Cooper. Ambegaoker and Kadanoff then show how the BCS theory can be made
gauge invariant. As a consequence of gauge invariance, superconductors have, in
addition to the quasi-particle excitations of BCS, collective excitations which can
be induced by an electric field. An excellent account of the scattering of electrons
by impurities in both normal and superconducting metals is given by Rickayzen.
Short chapters by Mittag on the dense electron gas and by Stephen on the diamagnetic susceptibility of an electron gas, round out the section on solid state
and low temperature studies.
This section is followed by a series of 4 articles on the nuclear many-body
problem. In a lecture entitled "Properties of the Nuclear Surface," Professor
46
PHYSICS IN CANADA
Rosenfeld manages, in addition to covering the topic at hand, to give a concise,
but lucid, account of several general methods or devices, e.g. the variational
principle and the self consistent field, the density matrix, and the Thomas-Fermi
method. The language of second quantization is used by G. E. Brown in an
extensive discussion of collective nuclear motions, and by J. S. Bell for a clear
exposition of superfluidity in nuclear matter. The final lecture in this section is a
review by Bell of the problem of hard core potentials in perturbation theory.
The Bergen lectures end with four contributions of rather varied nature.
A. Katz discusses the calculation of the moment of inertia of a many-fermion
system, A. J. Glick discusses the properties of the linear-response function from
which several important properties of the many-body system can be derived, and
R. Balian discusses the structure of the t-matrix of Brueckner and of the canonical transformation of Bogoliubov. Perhaps the most interesting contribution is
the article of Katz on the analytic structure of perturbation theory in which he
points out that, by analytic continuation, a perturbation series such as the Goldstone expansion may have significance far beyond its circle of convergence.
Finally, it might be remarked that the Bergen lectures are prefaced with a short
review of their contents by editor Christian Fronsdal.
In contrast to the Bergen lectures, the Quantum Theory of Many-Particle
Systems is a reprint collection. Specifically, it is a reprint collection on the fundamental contributions of Van Hove and Hugenholtz on the perturbation theory
of many particle systems. It is necessarily very partial to the work of Van Hove
and Hugenholtz, and while their formulation of perturbation theory in terms of
the resolvent operator has some distinct advantages, the alternative formulation
in terms of the development operator has been largely adopted in the current
literature. Moreover, it is rather vague as to its general purpose and represents a
rather mixed bag of items.
Nevertheless, the collection is a useful reference work for the serious student
of perturbation theory in the quantum mechanics of many-body systems. The
book begins with an expanded version of an MIT report by Van Hove entitled
"Interactions of Elastic Waves in Solids". This article gives an excellent review
of the classical and quantum theories of elastic solids, and demonstrates the use
of modern perturbation methods for handling anharmonic effects. In particular,
Van Hove discusses at some length neutron scattering at 0° K, and three basic
papers on neutron scattering and crystal dynamics are reprinted from the
Physical Review. Unfortunately, the reduction of page size from the Physical
Review to book form results in print which is too small for comfortable reading.
For this reason, the reader is likely to turn to the reprints from Physica with
a real sense of relief. Van Hove's two contributions on "Energy Corrections and
Persistent Perturbation Effects in Continuous Spectra", in which he discusses at
length the "cloud" and "self energy" effects in many-body perturbation theory,
are of more general interest to the field theorist than to the solid state physicist
The discussions are very good, however, and Van Hove outlines the resolvent
method in perturbation theory. This method is taken up in the classic paper of
Hugenholtz which makes extensive use of the diagrammatic analysis of Feynman
to discuss the quantum mechanics of many-body systems at zero temperature.
Particular attention is paid to the problem of separating out properly extensive
thermodynamic quantities in the perturbation treatment.
The method is applied to the Fermi gas model of heavy nuclei in a subsequent
reprint of Hugenholtz and the collection ends with an important paper of
Hugenholtz and Van Hove on single particle energies in an interacting Fermi
gas. In this paper, it is shown that the single particle concept for an interacting
Fermi gas at zero degrees has meaning only for those particles whose momenta
are approximately equal to the Fermi momentum.

Meteorites. By

of this book, authoritative information on these interesting
bodies has been widely scattered through the literature. Both specialists and
teachers of astronomy will welcome its appearance, though it is addressed more
to the former. After some introductory chapters and a description of the external
features of meteorites and their classification, the author discusses their mineralogy
and internal structure in great detail. Physicists may find themselves somewhat
intimidated by words like "enstatite" and "hypersthene", but they are no doubt
necessary in a mineralogical discussion. A long chapter gives a critical discussion
of the elemental composition of meteoritic matter. The various kinds of meteorite
ages are considered briefly but thoroughly. The book concludes with a chapter on
the origin of meteorites and one on tektites. Appendices discuss the chemical
analysis of meteorites and give a complete list of meteorites of the United States.
It appears that all specialists in the subject would want to have a copy of the
book, and that it should be in the library of any department which teaches
astronomy.
