A To Z Vidnyan

IN DAY-TO-DAY LIFE, WE COME ACROSS MANY WORDS AND DEFINITIONS. THE STUDENTS LEARN MANY THEOREMS AND OBSERVE MANY APPARATUS IN THEIR SCHOOLS. BUT, IF WE GIVE IT A SERIOUS THOUGHT THEN WE WILL REALIZE THAT MANY OF THEM ARE NOT FULLY AWARE OF THE MEANINGS OF THIS NAMES, DEFINITIONS OR APPARATUS. THE WHOLE PURPOSE BEHIND THE PUBLICATION OF THE BOOK "A TO Z` WAS TO HELP EVERYONE TO OVERCOME THIS DIFFICULTY. IN THIS BOOK, WE HAVE STARTED WITH THE MEANINGS AND EXPLANATIONS OF WORDS IN AN ALPHABETICAL ORDER. WE HAVE TRIED TO MAKE IT EASIER BY DRAWING FIGURES WHEREVER NECESSARY. THE AUTHOR HAS SO FAR WRITTEN DIFFERENT BOOKS ABOUT THE SCIENTIFIC TOYS, AND EXPERIMENTS. WE ARE SURE THAT THE READERS WILL ENJOY THIS BOOK AS WELL.....★★★★★★? ★★★★★★??? ★★★★★★????? ???? ????, ★★★★★★ ★★★★★★?? ?????. ????? ★★★★★★★★★★★★????? ★★★★★★★★★★★★ ★★★★★★???? ★★★★★★ ???? ★★★★★★?? ? ★★★★★★ ★★★★★★?? ?????; ????? ★★★★★★?? ???? ★★★★★★??? ????? ?????. ★★★★★★???
