Welcome you all NPS members on the 32nd Annual
Convention! We wish you all a very Happy and Prosperous
New Year 2016! May you have a great and a wonderful time
ahead!
This year becomes a very difficult time to us. Massive
Earthquake occurring on Baishakh 12 and 29, 2072 struck
our country that has destroyed much of her entire nation.
Along with many Nepalese, our two NPS members also lost
their lives in the earthquake. We were not able to enter the
NPS office for four months because of the building was
levelled as an unsafe due to the earthquake. As life had
started to become a normal condition, we announced to
organize 32nd NPS convention on 22-23 Ashwin 2072. The
situation again became horrible due to Taraian movement
and boarder blockade from southern neighbour as a reaction
of promulgation of Nepal Constitution 2072. Consequently,
the convention was pending and took time to organize this
convention as we were waiting for the recovery of the
normal situation in Nepal. We, on behalf of NPS executive
committee, would like to apologize for not being able to
organize the convention in time.
Last year, NPS held its Annual General Meeting (AGM) at
the Central Department of Physics, Kirtipur. Since the last
year publication of the NPS newsletter, some noteworthy
events have been transpired. We organized a couple of
scientific talks and seminars. Some of our NPS members
have acquired great achievements, and have involved on
several research activities including conference and seminar
organization on collaboration with the national and
international institutions.
January 2016
(Magh 2072)
NPS has published a Journal of Nepal Physical
Society (JNPS), a peer review research journal.
The main objective of the journal is to
encourage Nepalese physicists to publish their
research articles and to highlight the recent
findings in the field of physics. We have
included original and high-quality relevant
research articles from the fields of physics. This
is one of the great achievements of the NPS
activities.
Furthermore, the NPS sent a team of five
Nepalese Physics Champions along with two
members as a team leader to participate in the
46th International Physics Olympiad (IPhO) in
Mumbai, India. This team also participated on
Asian Physics Olympaid 2015 (APO15) held in
China. The most of the NPS effort has been
devoted for the selection procedure for IPhO
participants, the top 5 candidates throughout the
country. We are thankful to all professors/
faculties and NPS members who supported for
the selection and tutoring of the students.
Without their cherished support, it would have
been almost impossible to complete such tasks.
We highly appreciate the contribution of Prof.
Dr. Devendra Raj Mishra for his constant
involvement and guidance for the selection and
training for the participants. We are also grateful
to Mr. Basant Kumar Gautam, NPS life member,
for his cooperation to obtain the travel grant for
the IPhO participants.
On behalf of the NPS executive committee, I
would like to thank all the NPS members for
their significant supports to make the NPS
accomplishments successful. Finally, any
comments, queries, suggestions, and
correspondences are highly appreciable.

Publication of Journal of
Nepal Physical Society (JNPS)
Editorial Board of NPS has published the peer
review journal, the Journal of Nepal Physical
Society (JNPS). NPS used to publish the
research articles and conference proceedings
as an integral part of its activities since its
inception. However, the publication of the
journal could not be continuing on regular
way. The present issue of the publication is a
novel start toward the publication of a peer
review journal of the NPS. We have taken the
ISSN number of the JNPS and also it is
available in online in NepJol. Present issue of
the JNPS comprises of original research
articles contributed by our NPS members,
university faculties, researchers, and students
on contemporary issues in all the domain of
physics. The articles incorporated in this
journal are rigorously reviewed by the national
and international experts in their respective
fields. We, on behalf of the editorial board of
Nepal Physical Society, would like to thank
reviewers for their esteemed suggestions and
feedbacks to standardize the articles.

CONDOLENCE !!!
Nepal Physical Society suffered this year from a tragedy: the loss of life of the late Prof. Surdharsan Rishal,
Life Member of NPS. He died at the age of 78 on Aswin 20, 2072. Prof. Rishal was Founder Member and Vice
President of Nepal Physical Society. He was one of the most respected and popular teacher, an excellent
administrator in Nepal. Prof. Rishal did his M.Sc. in Physics in 2016 and then joined at Tri-Chandra College as
a Lecturer in Physics. He continued his service as an Professor in Physics from Amrit Science College. Prof.
Rishal served as a deputy registrar in Tribhuvan University (2029-2036) and also as a Registrar of Tribhuvan
University (2048-2051). He was honoured by several awards such as a senior scientist from NAST and
Fanindra Lohani Award from Nepal Physical Society.
NPS and Amrit Science Campus jointly organized
condolence program in the name of Late Prof. Rishal at
Amrit Science Campus, Lainchaur on Aswin 24, 2072.
Senior professors, faculties, NPS members, campus
chief, students and non--‐teaching staffs were attended
the program. The society expressed condolence to the
family and closet friends on sudden death of Prof.
Rishal, and heartily pray that his soul finds peace. His
close friends and colleagues highlighted the late Prof.
Rishal’s biography, his contribution to the university,
physics community and the whole nation.

Takaaki Kajita and Arthur McDonald won 2015 Physics Nobel Prize Takaaki Kajita and Arthur McDonald The Royal Swedish Academy of Sciences awarded 2015 Nobel Prize in Physics to the two
experimenters, Takaaki Kajita of Tokyo University, and Arthur McDonald of Queen’s University in
Kingston, Ontario for their discovery that neutrinos oscillate in flavor. After photons, neutrinos are
the most abundant particle in the universe. Their ubiquity, however, comes with an infinitesimal
propensity to react with matter. Every second, trillions of neutrinos—some created in the Big
Bang, some spewing from distant supernovas, some emanating from inside the Sun—stream
through our bodies without our noticing.
Detecting neutrinos is hard. Measuring their mass and some other properties is harder still. Kajita's
and McDonald's teams designed, built, and ran huge experiments that sought to determine one of
the most important neutrino properties of all: whether the particle oscillates among its three flavors
—electron, muon, and tau.
Kajita was team leader at the Super-Kamiokande neutrino observatory at Hida Japan. McDonald
directed the Sudbury Neutrino Observatory, near Toronto, Canada.
The affirmative and conclusive confirmations from the two facilities, obtained almost two decades
ago, constituted proof that at least one neutrino eigentstate is endowed with mass. That finding has
profound implications for physics. It requires that the standard model of particle physics, which
had originally presumed neutrinos to be massless, be extended.
The finding also suggests that the solution to one of the biggest outstanding problems in physics—
the preponderance of matter over antimatter—might be found in the nature and behavior of
neutrinos.
•  The story of neutrino oscillations involves not just particle physics, but also nuclear physics and
astrophysics. Wolfgang Pauli proposed the existence of a new neutral particle in 1930 to preserve
the conservation of energy, momentum, and spin in beta decay. Whatever it was, the hypotheical
particle—dubbed the neutrino by Enrico Fermi—was evidently light, fast, and feebly reactive.
