Thank you !
I teared up when I found this on the Itunes store. I'm a 9th grade dropout that made some bad decisions in high school and never went to college. Years later I have found an extreme thirst for knowledge and am trying to self educate to try and clept out of some classes so I can get my degree quicker. Through some of these online classes and lectures I can slowly get the education I so desperately want. Thank you for posting and even better providing it free.
THANK YOU!!!! (I'm 13)
Omg thanks so much I want to excel in math more!! So thanks for posting this!
A Perfect Introduction to Physics
Dr. Shankar gives a profound insight to his students and podcast listeners alike, by describing classical mechanics up to quantum principles in a coherent fashion. Although, I am still a high school senior; I've been accepted to Cal State Northridge and I choose physics as my major because of my inquiry of the physical universe around me. This gave me a sense of what professors might expect from their students, I also realized that the mathematics is calculus based throughout these lectures. It might be a bit difficult for those of us who aren't mathematical as Newton, Einstein, Bohr, Laplace, and Heinsberg. However, every lecture ranges from topics like quantum mechanics, vector analysis, special relativity, and so forth. I totally recommend this for anyone who has an intrest in physics and for those who might want to major in a field related to it. I love physics and my dream is to recieve a PhD in some area that concerned with that section of science, almost every day I read articles from NOVA or read encyclopedia articles about physics.
