Watch Richard Feynman in Conversation, 1973

In 1973, physicist and master explainer Richard Feynman visited England on vacation. At the time he was a physics professor at CalTech, and his English wife and son joined him on the trip. A local TV channel produced a 36-minute short film featuring Feynman called Take the World from Another Point of View.

The film is classic Feynman-as-explainer. He wheels about in conversation with astrophysicist Fred Hoyle (who coined the phrase "Big Bang"), discussing questions big and small. At one point Feynman discusses how his branch of science, physics, is treated differently from other branches—and how perhaps that isn't right. Here's that snippet:

It is interesting that in many other sciences there is a historical question, like in geology—the question of how did the earth evolve to the present condition. In biology—how did the various species evolve to get to be the way they are? But the one field which has not admitted any evolutionary question is physics. Here are the laws, we say. Here are the laws today. How did they get that way?—we don't even think of it that way. We think: It has always been like that, the same laws—and we try to explain the universe that way. So it might turn out that they are not the same all the time and that there is a historical, evolutionary question.

100 Fascinating Facts About Earth

The best Spaceball.
The best Spaceball.
NASA

Did you know that there’s a place in the South Pacific Ocean called Point Nemo that’s farther from land than any other point on Earth? So far, in fact, that the closest humans are usually astronauts aboard the International Space Station. (And by the way: The map you’re about to look for Point Nemo on might not be entirely accurate; a certain amount of distortion occurs when trying to depict a 3D planet on a 2D surface.)

In this all-new episode of The List Show, Mental Floss editor-in-chief Erin McCarthy is journeying to the center of the Earth, and visiting its oceans, its atmosphere, and even space, in search of 100 facts about our endlessly fascinating planet.

The subjects that fall under the umbrella of “facts about Earth” are nearly as expansive as Earth itself. Geology, biology, astronomy, and cartography, are all fair game—and those are just a few of the many -ologies, -onomies, and -ographies you’ll learn about below.
