Still wondering why leaves are green and not purple or even black? CHLOROPHYLL! It's how leaves work.

This video is about elastic and inelastic collisions in 1D, 2D and 3D - and how the collision of conservation of energy with conservation of momentum, plus a secret direction, results in a completely predetermined behavior for most...

In elections, your vote may be influenced by design of the ballot itself, especially when you don’t have strong feelings about which candidate to elect.

So how can a game teach us about engineering? Pretty easily! When you're trying to solve a game, or a puzzle, or whatever, you will have a bunch of variables. The trick is knowing how to change one variable at a time to see what changes....

Every day, we make decisions that have good or bad consequences for our future selves. (Can I skip flossing just this one time?) Daniel Goldstein makes tools that help us imagine ourselves over time, so that we make smart choices for...

Designing electronics is generally cumbersome and expensive -- or was, until Leah Buechley and her team at MIT developed tools to treat electronics just like paper and pen. In this talk from TEDYouth 2011, Buechley shows some of her...

The workplace is often presented as a meritocracy, where you can succeed by putting your head down and working hard. Wall Street veteran Carla Harris learned early in her career that this a myth. The key to actually getting ahead? Get a...

It's time to design some trials. Sometimes engineers need to figure out how to test ideas. In order to do that, we need to design trials to find failure points and see how things are going to work in the real world (with gravity, wind,...

How long will it take to win a game of chess on an infinite chessboard?

More trials! This time we need to figure out what to do if you don't have all the things you'd like to have to perform your tests. How do you isolate a variable across multiple tests? A good engineer will work to find a way to make it...

Would you like to play a game, Dr. Falken? Actually, this episode isn't really about games, or Matthew Broderick, or Thermonuclear War. But enough with the long references to 1983's best movie, War Games. Today Jacob and Adriene are...

Imagine a game played with two players and two dice: if the biggest number rolled is one, two, three, or four, player 1 wins. If the biggest number rolled is five or six, player 2 wins. Who has the best probability of winning the game?...

Imagine you're watching a runaway trolley barreling down the tracks, straight towards five workers. You happen to be standing next to a switch that will divert the trolley onto a second track. Here's the problem: that track has a worker...

Discover what happens when random events meet allele frequencies: genetic drift! This Amoeba Sisters video also discusses the bottleneck and founder effect as well as contrasts genetic drift with natural selection. Table of Contents:...

The classical physics that we encounter in our everyday, macroscopic world is very different from the quantum physics that governs systems on a much smaller scale (like atoms). One great example of quantum physics' weirdness can be shown...

People have been grappling with the question of artificial creativity -- alongside the question of artificial intelligence -- for over 170 years. For instance, could we program machines to create high quality original music? And if we...

A video entitled "Independent Events" which shows how to tell is two events are dependent or independent.

A video entitled "Mutually Exclusive Events" which explains how to tell if something is a mutually exclusive event.

A video entitled "Conduct Simulation" which shows how to build a simulation to solve a multi variable probability problem.

“We have to, as a country, understand that equity is the route to fairness when there’s inequality.” Kevin Skwira-Brown’s presentation at the Our Kids Solutions Forum greatly impacted the audience. Kevin is a teacher, a community...
