Six Easy Pieces: Essentials of Physics By Its Most Brilliant Teacher

Once, during a public lecture, he was trying to explain why one must not verify an idea using the same data that suggested the idea in the first place. Seeming to wander off the subject, Feynman began talking about license plates. “You know, the most amazing thing happened to me tonight. I was coming here, on the way to the lecture, and I came in through the parking lot. And you won’t believe what happened. I saw a car with the license plate ARW 357. Can you imagine? Of all the millions of license plates in the state, what was the chance that I would see that particular one tonight? Amazing!”

(After all, light and gamma rays are all the same; they are just different points on a frequency scale.)

magnetic forces and electric forces can really be attributed to one

The electromagnetic field can carry waves; some of these waves are light, others are used in radio broadcasts, but the general name is electromagnetic waves. These os

rays coming from nuclei are called gamma rays, while those of high energy from atoms are called x-rays,

All these details can be worked out if the situation is simple enough for us to make an approximation, which is almost never, but often we can understand more or less what is happening.

In this one theory we have the basic rules for all ordinary phenomena except for gravitation and nuclear processes.

field, as two different aspects of exactly the same thing.

Magnetic influences have to do with charges in relative motion

light. That is how one gets flames.
