What Is the Electric Constant and Why Should You Care?

wired.com Rhett Allain 2025-11-20 03:00:00

It's fun to think about the fundamental physical constants. These are special values used in our models of the physical universe.

We use these in solving physics problems all the time, so it’s easy to take them for granted. But why are there such numbers in nature, and why do they just happen to

Or that we’re trying to lay off humans. And that was not the intent at all.” On the contrary, von Ahn sai

The latest episode of Star Trek: Strange New Worlds planted the seeds for what’ll eventually become classic Star Trek by giving James Kirk (Paul Wesley) time in the captain’s chair.

In this week’s “The Sehlat Who Ate Its Tail,” Kirk and the Farragut crew have to rescue the Enterprise from the tendrils of a power-draining scavenger ship.
