Watch: Richard Feynman makes scientific concepts beautifully simple

Few could match the famous physicist in his ability to communicate difficult-to-understand concepts in a simple and warm fashion.

  • Richard Feynman was a renowned physicist who conducted legendary work on quantum physics, the Manhattan Project, and investigating the Challenger explosion.
  • Later in life, however, he became best known for his education work, gaining the nickname "the Great Explainer."
  • His series, Fun to Imagine, works as an excellent primer to Feynman's unique educational style. Here are 9 science lessons he covers in his series.

In 1964, during a lecture at Cornell University, the physicist Richard Feynman articulated a profound mystery about the physical world. He told his listeners to imagine two objects, each gravitationally attracted to the other. How, he asked, should we predict their movements? Feynman identified three approaches, each invoking a different belief about the world. The first […]

  • The fine structure constant has mystified scientists since the 1800s.
  • The number 1/137 might hold the clues to the Grand Unified Theory.
  • Relativity, electromagnetism and quantum mechanics are unified by the number.

Could an updated Feynman experiment finally lead to a Theory of Everything?

Measuring quantum gravity has proven extremely challenging, stymying some of the greatest minds in physics for generations.

For over a century, the two leading theories in physics have had irreconcilable differences, and scientists have scrambled to find ways to square them, to no avail. An experiment proposed in 1957 by American luminary Richard Feynman, is now getting a makeover, and the results could be significant.

Why Searching for a Theory of Everything Is Better Than Finding It

Will we ever have a Theory of Everything? Theoretical physicist Lawrence Krauss isn't sure that's the right question to be asking.

It’s no surprise that understanding highly abstract mathematics can be challenging, says theoretical physicist Lawrence Krauss. The organ of your body that does the understanding — the brain — is like the organ that does the waste processing — the kidney. Both are products of millions of years of evolution, and neither will change overnight. The type of thinking that helped us survive on the African savannas doesn’t help us grasp quantum mechanics. We should expect to not understand everything about the universe, and to keep asking questions…
