I drive 45 mins one way to class 5 days a week and started thinking maybe it wouldn't be so miserable if I had something interesting to listen to instead of the same music over and over. I'm a mech engineering undergrad with an aerospace concentration, at I'd guess the sophomore level. Not completely sure since I transferred in, but currently only in calculus 2 and physics 1 if that makes a difference on section. I'm really interested in physics and engineering topics, as well as maybe a good biography of a great physicist/engineer. Einsteins life intrigues me but there are so many books about him that I'm not sure which would be better. With my current level Of education and only wanting an audiobook, it'd have to more about concepts and the basics of whichever subject. Thank you so much for the help!
