The Physics of Sandcastles

Give a plastic bucket and a shovel to a child, then turn her loose on a beach full of sand. She'll happily toil the day away building the sandcastle to end all sandcastles. It's pure fun. It's also ... Continue reading

So much going on in a grain of sand.

The Weakest Force

Did you know that gravity is the weakest force in the universe? Well, it's true! There are four fundamental forces (that we know of) in our universe: Strong Nuclear, Electromagnetic, Weak Nuclear ... Continue reading

Carbon Dating From The Skies

Determining the age of relatively recent fossils, those of plants and animals that lived tens of thousands of years ago, is not a guessing game but an exact science. By using carbon dating we can ... Continue reading

Carbon dating the bones of an animal can pinpoint the time this animal died to within a few years.
