Acknowledgement
I have great pleasure in expressing my gratitude to Prof.
V.G. Kulkarni, ex-Director, Homi Bhabha Centre for Science
Education (HBCSE), Tata Institute of Fundamental Research
(TIFR), Bombay, for extending all support and facilities·
to me while the book was in preparationJ am extremely
grateful to Dr H.C. Pradhan, who was instrumental in
inducing me to write this book. He had critically read the
manuscript and made valuable suggestions. I thank him for
his constant support and encouragement. br Seema Purohit
of Kirti College, Bombay, had carefully gone through the
manuscript and made valu�ble suggestions. I express my
sincere thanks to her. I wish to express my thanks to Shri
Arun Mavalankar, who had· taken the responsibility of
preparing the press copy of the manuscript;-Shri V.N. Gurav,
who put the manuscript on the word processor and Shri
Shivaji Nadkar, who carefully xeroxed it. All these staff
members at HBCSE had been very helpful to me. I must
thank Nilesh, Sameer, Vrinda and Dhanashree, all members
of my family for the pains they took in preparing a few
illustrations included in the manuscript before they were
redrawn at NBT.
This book could not have been complete without the
persistent follow-up by Ms Manju Gupta, Editor, National
Book Trust, who has patiently borne the delay in writing the
book. I sincerely thank her for her kind appreciation and
encouragement.
