**Description:**

Special Theory of Relativity and Quantum Theory are
considered as the two major revolutions of the 20^{th} century. Roger
Penrose wrote “Albert Einstein had such extra-ordinary deep perceptions of the
workings of Nature that he laid foundation stones for both of these twentieth
century revolutions in the single year of 1905”. The year 1905 was Einstein’s *Annus Mirabilis* (Year of Miracles) when
he was working, in almost total isolation, in the Swiss Patent Office. In this
small book, the author - Ajoy Ghatak gives the basic physics and consequences
of his revolutionary contributions in his Year of Miracles: *E=mc*^{2}*, The Light Quantum & Special
Theory of Relativity*.

About the Author:

**Ajoy Ghatak** was Professor of Physics at
IIT Delhi; he is currently Professor Meghnad Saha Fellow of NASI (The National
Academy of Sciences, India). He received his B.Sc. from Agra College, M.Sc.
from Delhi University and Ph.D. from Cornell University. He was a Research
Associate at Brookhaven National Laboratory for about a year and a half and
then he was with Delhi University for about 1 year after which he joined IIT
Delhi in 1966 where he became a Professor in 1974.

Professor
Ghatak has research interests in Fiber Optics and Quantum Mechanics. He has
authored several books including his undergraduate text on *OPTICS *which
has been translated to Chinese and Persian. His other books include *Fiber
Optics, Optical Electronics *and* Lasers* (all 3 co-authored with Prof.
K. Thyagarajan), *Quantum Mechanics* (co-authored with Prof. S.
Lokanathan), *Mathematical Physics* (co-authored with Prof. I. C. Goyal and Prof. S. J. Chua) and a popular book *Albert Einstein:
The Story of a Genius*. He is recipient of the 2008 SPIE Educator award
in recognition of “his unparalleled global contributions to the field of fiber
optics research, and his tireless dedication to optics education worldwide..”;
the 2003 Esther Hoffman Beller Award (instituted by The Optical Society of
America) in recognition of his “outstanding contributions to optics
education …” ; International Commission for Optics 1998 Galileo Galilei Award
and also the CSIR 1979 S.S. Bhatnagar Award for “outstanding
contributions in physical sciences”. He received D.Sc. (Honoris Causa) from
University of Burdwan in 2007.
