The leaves are falling from the trees and the air is getting chilly where Jessi and Squeaks live, which can only mean one thing: it's fall! And to celebrate the season, they've put together a bunch of videos about all the fun things you...

With his team at SENSEable City Lab, MIT's Carlo Ratti makes cool things by sensing the data we create. He pulls from passive data sets -- like the calls we make, the garbage we throw away -- to create surprising visualizations of city...

We have all changed someone's life -- usually without even realizing it. In this funny talk, Drew Dudley calls on all of us to celebrate leadership as the everyday act of improving each other's lives.

Can architects re-engineer their design process? Joshua Prince-Ramus shows how the results can be spectacular. He walks us through his fantastic re-creation of the Wyly Theater as a giant "theatrical machine" that reconfigures itself at...

What makes you, you? Is it how you think of yourself, how others think of you, or something else entirely? Philosopher Julian Baggini draws from philosophy and neuroscience to give a surprising answer.

Military leaders have known for millennia that the time to prepare for a challenge is before it hits you, says scientist and retired US Navy officer David Titley. He takes us from the humanitarian catastrophe in Syria to the icy shores...

CALCULUS! Today we take our first steps into the language of Physics; mathematics. Every branch of science has its own way to describe the things that it investigates. And, with Physics, that's math. In this episode, Shini talks us...

In this, THE FIRST EPISODE of Crash Course Physics, your host Dr. Shini Somara introduces us to the ideas of motion in a straight line. She talks about displacement, acceleration, time, velocity, and the definition of acceleration. Also,...

Each snowflake is a six-pointed work of art, as cool and as individual as you are. But how does nature make snowflakes?

In this video Paul Andersen explains how the average value of the electric field can be determined by dividing the potential difference by the displacement. Equipotential lines can be used to determine the potential in an electric field...
