Under-Graduate Quantum Mechanics

You may be thinking what’s the need in life to study Quantum Mechanics? My answer for this question will be because we are living in Quantum World. Now a day’s Engineers Physicist Chemist Biologist want to create or control devices at atomic scale. And quantum mechanics gives us a way to study create and control things at the atomic scale. Best example of this is in 1947 first transistor was invented whose size was 2 cm and now a days we are able to make 20 nm transistors. In this book we are going to emphasize Quantum Mechanics which will helpful for under-graduate students.
