The renowned physicist and polymath Freeman Dyson passed away near Princeton, New Jersey, on Feb. 28, at the age of 96.

Why it matters: Dyson was a dazzling scientist, but his true genius lay in his astonishing imagination, which reached for the farthest edges of the cosmos.

  • In 1949, Dyson tackled one of the trickiest problems in the field: how to describe the behavior of electrons and photons.
  • Dyson's insight, which came to him while riding a Greyhound bus through Nebraska, proved key to quantum electrodynamics, which the physicist Richard Feynman called the "jewel of physics."

Dyson never won a Nobel Prize for his work. He never even bothered to earn a Ph.D.

The bottom line: Few scientists can be said to have played as important a role in the making of our present than Dyson — and even fewer could so brilliantly envision the future.

Deaths without consequences

Seven years after the launch of the Black Lives Matter movement, it's still rare for police officers to be charged in the deaths of African Americans — and even more rare for an officer to go to jail.

The big picture: The Minneapolis police officer who was captured on video kneeling on George Floyd's neck has been charged with third-degree murder and manslaughter — which is already a step beyond the consequences other police officers have faced. But it's no guarantee that he will face jail time.
