1/14 ✤ The Feynman Lectures on Physics— This lecture was presented by Dr. Richard Feynman on October 6th, 1961 at the California Institute of Technology. Volume 1, Chapter 4: Conservation of Energy ✤ There are— will be no summary of the previous lecture, huh. There’s no [1. summary] of the previous lecture. You just to remember whatever you can remember from it. No vital points. ✤ The, uh, next two lectures after today will be given by Professor Matt Sands because I’m going to a meeting in, uh, Brussels. So, I’ll come back, uh, next Tuesday, (and) I mean the Tuesday following. Tuesday, January 31, 2012

2/14 ✤ Section 4.1: What is energy? ✤ Today’s lecture is on, uh, one of the laws of physics, and, uh, beginning, of course, [t] uh, detailed looking at the different aspects of physics. We just finished, uh, description of, uh, things in [2. general] and now we look more specifically, in particular, what a law of physics looks like. And so I picked one out uh/as to illustrate the ideas and a kind of reasoning that might be used in, say, theoretical physics. So, the lecture today is on the conservation of energy . Tuesday, January 31, 2012

3/14 ✤ There is a fact, or if you wanna call it a “law,” governing all natural phenomena that’s known today there’s no exception known to this. It’s exact as far as we know. And the [3. law’s] called the conservation of energy . ✤ It states: there is a certain quantity, and which we call energy, that doesn’t change in, uh, manifold changes which nature undergoes. ✤ Now that’s a very abstract idea because it’s a mathematical principle. It says there’s a numerical quantity that doesn’t change when something happens. Tuesday, January 31, 2012

4/14 ✤ It’s not a description of a mechanism, or anything. It’s just a strange fact that you can calculate some number and when you all finish watching [4. nature] go through her tricks and calculate a number again, and it’s the same. Something like the bishop is on the red square now, and after a number of moves, details are unknown, it’s still on some red square. It’s a law of this nature. ✤ Since it’s an abstract idea, I would like to illustrate the meaning of it with a lot of pecu— uh silly example(s) but it does illustrate the idea. Tuesday, January 31, 2012

5/14 ✤ I want you to imagine a child, perhaps Denis the Manis , who has blocks. But you must appreciate that these blocks are absolutely indestructible and cannot divided into pieces. They’re just— each is the same as the others. (And) I will suppose that he has, say, 28 blocks. ✤ Now, this child is [5. put] into a room by his mother, at/and the beginning of the day with these 28 blocks. At the end of the day, I don’t know why she’s so curious but she counts the blocks very carefully and discovers a phenomenal law that no matter what he does with the blocks, there are always 28 blocks. Tuesday, January 31, 2012

6/14 ✤ So, this goes on for a number of days, until one day there are 27 blocks, but uh a little [6. looking] around shows that there’s some under the log. You have to be careful to make it sure that you looked everywhere in order to make it sure that the number of blocks doesn’t change. ✤ One day, however, the number of blocks appears to change. There’re only 26 blocks. [7. Careful] investigation indicates that the window was open and now looking outside, you can find other two blocks. So, you bring them back in again and everything’s alright. Tuesday, January 31, 2012

7/14 ✤ Another day, careful [8. count] indicates the existence of 30 blocks. (Laughter) This causes a considerable concinnation until it was realized that Bruce came to visit and he owned blocks and left perhaps a few. ✤ So, after you get rid of some of these things, we close the window, we don’t [9. let] Bruce in then we see everything is going along alright until one time we count 25 blocks.
