English for students of Physics

My profound gratitude would go first to Mr. Nguyen Van Mau; Mr. Mai Trong Nhuan;

Mr. Tran Huy Ho; Mr. Bui Duy Cam; Mr. Nguyen Chi Dung and Mrs. Tran Thi Nga at Hanoi

University of Sciences who have made it possible for my work tobe carried out and

accomplished so far.

My sincere thanks would specially go to Mr. Ton Tich Ai for his help and supervision on

Physics matters dealt with throughout the book; without which, my book would have been

completely invalid in Physics
