War - Crash Course Statistics
Today we're going to discuss the role of statistics during war. From helping the Allies break Nazi Enigma codes and estimate tank production rates to finding sunken submarines, statistics have and continue to play a critical role on the...

TED-Ed: What is the Heisenberg Uncertainty Principle? - Chad Orzel
The Heisenberg Uncertainty Principle states that you can never simultaneously know the exact position and the exact speed of an object. Why not? Because everything in the universe behaves like both a particle and a wave at the same time....

Quantum Tunneling Takes a Surprisingly Long Time
Quantum tunneling happens when a particle seemingly teleports across a barrier. But despite how instantaneous this event sounds, recent research suggests that it doesn’t happen nearly as fast as you might think.

TED-ED: Why do airlines sell too many tickets? - Nina Klietsch
Have you ever sat in a doctor's office for hours, despite having an appointment? Has a hotel turned down your reservation because it's full? Have you been bumped off a flight that you paid for? These are all symptoms of overbooking, a...

TED-Ed: The method that can "prove" almost anything | James A. Smith
In 2011, a group of researchers conducted a study designed to find an impossible result. Their study involved real people, truthfully reported data, and commonplace statistical analyses. So how did they do it? The answer lies in a...

TED-Ed: The mathematical secrets of Pascal's triangle - Wajdi Mohamed Ratemi
Pascal's triangle, which at first may just look like a neatly arranged stack of numbers, is actually a mathematical treasure trove. But what about it has so intrigued mathematicians the world over? Wajdi Mohamed Ratemi shows how Pascal's...

Intelligent Design: Crash Course Philosophy
Last week we introduced Thomas Aquinas’s four cosmological arguments for the existence of god; today we introduce his fifth argument: the teleological argument, and the ensuing dialogue it initiated.

Geometric Distributions and The Birthday Paradox - Crash Course Statistics
Geometric probabilities, and probabilities in general, allow us to guess how long we'll have to wait for something to happen. Today, we'll discuss how they can be used to figure out how many Bertie Bott's Every Flavour Beans you could...

Hardy-Weinberg Punnett Square
In this video Paul Andersen explains how you can combine the power of a Punnett square for an entire gene pool. Hardy-Weinberg equilibrium will remains constant under several constrains and the probability square makes the information...

Kepler's Planetary Bonanza
You've know that the Kepler Space Telescope has discovered HUNDREDS of new planets outside our solar system -- but how does it find them? And how do scientists tell the real planets from the celestial fake-outs? It involves a lot of...

P-Value Problems - Crash Course Statistics
Last week we introduced p-values as a way to set a predetermined cutoff when testing if something seems unusual enough to reject our null hypothesis - that they are the same. But today we’re going to discuss some problems with the logic...

TED-Ed: Will there be another pandemic in your lifetime? | TED-Ed
We tend to think of pandemics as unlikely events, but disease outbreaks are surprisingly common. Over the past 400 years, the longest stretch of time without a documented outbreak was just four years. So, what's the probability of...

TED-ED: What is entropy? - Jeff Phillips
There's a concept that's crucial to chemistry and physics. It helps explain why physical processes go one way and not the other: why ice melts, why cream spreads in coffee, why air leaks out of a punctured tire. It's entropy, and it's...
