Professor Lewin has made Physics look simple, wonderful, and lovely. I have got a PhD in Physics. Studying something is different from understanding it. Honestly speaking, his amazing lectures taught me what Physics is. I'd like to thank him for his great attempts and efforts in teaching Physics.

Dear Prof. Lewin, I am a huge fan of yours. The first time I heard about your video lectures was in my first year at the University (I studied physics for becoming a high school teacher in Austria). A dutch friend of mine showed me your videos and said proudly that you are from the Netherlands. Some years later a friend of my parents watched all your courses and he said to my parents that I can learn a lot from you. This year is my second year as a teacher in high school and last year another teacher was sick and so I was teaching instead of him. I made an introduction to electricity and used some of your ideas, experiments and explanations from your video lectures. For example I referred to the „fire“ as Benjamin Franklin called it. At that day a pupil went to the principal of the school for a different reason, but the pupil was also taking positive about my introduction to the principal. Thank you and the film crew very much! I have a few question to you and I am looking forward to your answer: Do you know the book „Conceptual Physics“ from Paul Hewitt and if you know the book what do you think about it? Do you have book or video advices for me as a beginning physics teacher?

I suggest you start watching my 8.01 lectures and see whether you can handle the calculus and the simple differential eqs. Then do the same for 8.02 and after that 8.03. The math will get more difficult but perhaps you can handle it. The math needed for QM (quantum field theory) and for General Relativity is MUCH more difficult.

+Lectures by Walter Lewin. They will make you ♥ Physics. Hi Professor Lewin... It turnes out that mineral electrolites such as potasium and chloride, ect and antioxidents such as vitamin A, C and E, ect are all huge electron donors and neutralize free radicals or proton ions. When we are born and when we are very young, we have more negative charge than positive charge, but over time we loose this overbalance of electron advantage and become cationic overall. To combat this proton over ballance, we can rebuild our negative charge by grounding to the earth, (because the Earth carries a negative charge at the surface) and we can further build negative charge with electrolites and antioxidents. The health implications of negative charge and negative ions are profound and I would like to recieve the Nobel Prize for the work I have done and for the work of countless others who have made this understanding possible. My understanding of electrostatic charge was made posible in part through MIT OCW and by some very dedicated peple at MIT and by many others who have shared their understanding on this life changing revolution. Understanding negative electron charge is truly the greatest health breakthrough of the 21 st Century. Thank you again so much.

Is it because the confetti has both positive and negative charges on both sides. The side of the paper bit which is more positive is attracted and stuck but the side of paper bit which has more negative charge(along with positive) is first attracted then repelled to comb which is negative.

We can measure the direction of the magnetic dipole field from Earth. Near the geographic South pole the magnetic field lines are UP, thus that is the magnetic North pole. Near the geographic North pole the magnetic field is pointing down. Thus the magnetic North pole is near the geographic South pole and the magnetic South pole is near the geographic North pole.
@noelroberts29608 жыл бұрын
So to echo the other person responding here, is that if you look at a magnet, one end of the magnet is the magnetic south, while the other is the magnetic north. You can use a tool that you bring to the magnet will tell you which end is N and S. If you were to take that tool theoretically to the magnetic pole located in Canada (Northern Hemisphere), it would show that pole to be magnetically a South pole, and the magnetic pole in the southern hemisphere would be shown as N. So the North Magnetic Pole is actually magnetically south, and vice versa. Hope this helps. Another way to remember is that the compass magnet itself has its magnetic north pole pointing to the Northern Hemisphere's magnetic pole.

The Earth Magnetic field is a dipole field (magnetic monopoles do not exist). A magnetic compass has a magnetic needle. When the needle was made magnetic, the North pole of the needle was colored RED. This red end of the needle will be attracted by a the South pole of any magnet thus also by the Earth magnet. Since the red end of the needle will point to the North, the magnetic pole of the Earth which is close to the geographic North pole, is actually the Earth magnetic SOUTH POLE.
