The Trebuchet Challenge | Space Time
Kinetic and potential energy are defined as combinations of more basic quantities: position, velocity and mass. These combinations are chosen so that their sum is conserved. It’s actually remarkable that there’s any such combination of...

Why Do Fish School?
You might think that fish ride the undercurrents with all their buds to avoid the hungry mouths of predators - safety in numbers, right? But, it turns out, there’s more to consider when asking why fish swim in schools.

Deb Roy: The birth of a word
MIT researcher Deb Roy wanted to understand how his infant son learned language -- so he wired up his house with videocameras to catch every moment (with exceptions) of his son's life, then parsed 90,000 hours of home video to watch...

Newton’s Third Law and Gravitational Force Review
Newton’s Third Law states that for every force exerted by one object on another, the second object exerts an equal and opposite force on the first. These forces act simultaneously and are external to the system, meaning they don't change...
