That’s what they’re very good at — making decisions. I thought it was very remarkable how a problem of whether or not information as to how the bomb works should be in the Oak Ridge plant had to be decided and could be decided in five minutes. So I have a great deal of respect for these military guys, because I never can decide anything very important in any length of time at all. In five minutes he said, “All right, Mr. Feynman, go ahead.

When a photon comes down, it interacts with electrons throughout the glass, not just on the surface. The photon and electrons do some kind of dance, the net result of which is the same as if the photon hit only on the surface.

When sunlight, which contains red, yellow, green, and blue light, shines on a mud puddle with oil on it, the areas that strongly reflect each of those colors overlap and produce all kinds of combinations which our eyes see as different colors...This phenomenon of colors produced by the partial reflection of white light by two surfaces is called iridescence, and can be found in many places...the more you see how strangely Nature behaves, the harder it is to make a model that explains how even the simplest phenomena actually work.
