## Stopping Electricity – Faraday Cages

In 1755, Benjamin Franklin, curious about the workings of electricity, began testing various hypotheses. In one of his experiments, Franklin took an electrified silver can and dangled an uncharged cork ball (attached to a non-conductive silk string) into the can. The cork ball was not attracted to the interior of the electrified can. Puzzled, Franklin […]

## String Theory Explained – What is The True Nature of Reality?

What is the true nature of the universe? To answer this question, humans come up with stories to describe the world. We test our stories and learn what to keep and what to throw away. But the more we learn, the more complicated and weird our stories become. Some of them so much so, that […]

## Why the solar system can exist

Have you ever wondered how the earth stays in orbit around the sun? I mean, the pull of gravity is stronger the closer you are to the sun, so you’d think that if the earth got bumped slightly towards the sun (like, if you jumped, or something), then the sun would pull just a little […]
