"I'm Walter Lewin.
My lectures will in general not be a repeat of your book but they will be complementary to the book. The book will support my lectures. My lectures will support the book. You will not see any tedious derivations in my lectures. For that we have the book. But I will stress the concepts and I will make you see beyond the equations, beyond the concepts. I will show you whether you like it or not that physics is beautiful.
And you may even start to like it. I suggest you do not slip up, not even one day, eight oh two is not easy. We have new concepts every week and before you know you may be too far behind. Electricity and magnetism is all around us. We have electric lights. Electric clocks. We have microphones, calculators, televisions, VCRs, radio, computers. Light itself is an electromagnetic phenomenon as radio waves are.
The colors of the rainbow in the blue sky are there because of electricity. And I will teach you about that in this course. Cars, planes, trains can only run because of electricity. Horses need electricity because muscle contractions require electricity..."
