The Feynman Lectures on Physics Vol 1 by Richard P. Feynman
My rating: 5 of 5 stars
A text book, world famous and in the most lucid language of Physics. I have studied a few chapters intensively although I own this book [I have purchased this book multiple times due to relocation] You can guess its importance. Its for those who want to understand how legendary minds really work. Good for a physics student and good for those who want to do research of any kind on such a text, physics or other wise.
