El patrón geométrico de la belleza - Un recorrido por diferentes obras artísticas y su relación con la geometría y las matemáticas. Se utiliza la figura de un cubo como hilo conductor, una figura geométrica que, al ser cortada por un plano, puede dar lugar a un cuadrado, un triángulo equilátero, un pentágono no regular o un hexágono. También se comprueba cómo esas secciones están presentes en distintas obras artísticas y ornamentales.

The Infinite Hotel, a thought experiment created by German mathematician David Hilbert, is a hotel with an infinite number of rooms. Easy to comprehend, right? Wrong. What if it's completely booked but one person wants to check in? What about 40? Or an infinitely full bus of people? Jeff Dekofsky solves these heady lodging issues using Hilbert's paradox.

Archimedes once said "Give me a place to stand, and I shall move the Earth." While the idea of a person moving such a huge mass on their own might sound impossible, chances are you've seen this idea in action at your local playground. Andy Peterson and Zack Patterson use the seesaw to illustrate the amazing implications and uses of the lever.

Every day, we are bombarded by attention grabbing headlines that promise miracle cures to all of our ailments -- often backed up by a "scientific study." But what are these studies, and how do we know if they are reliable? David H. Schwartz dissects two types of studies that scientists use, illuminating why you should always approach the claims with a critical eye.

Population statistics are like crystal balls -- when examined closely, they can help predict a country's future (and give important clues about the past). Kim Preshoff explains how using a visual tool called a population pyramid helps policymakers and social scientists make sense of the statistics, using three different countries' pyramids as examples.

Why can we find geometric shapes in the night sky? How can we know that at least two people in London have exactly the same number of hairs on their head? And why can patterns be found in just about any text - even Vanilla Ice lyrics? PatrickJMT describes the Ramsey theory, which states that given enough elements in a set or structure, some interesting pattern among them is guaranteed to emerge.

Statistics are persuasive. So much so that people, organizations, and whole countries base some of their most important decisions on organized data. But any set of statistics might have something lurking inside it that can turn the results completely upside down. Mark Liddell investigates Simpson's paradox.

Taking that internship in a remote mountain lab might not have been the best idea. Pulling that lever with the skull symbol just to see what it did probably wasn't so smart either. But now is not the time for regrets because you need to get away from these mutant zombies... fast. Can you use math to get you and your friends over the bridge before the zombies arrive? Alex Gendler shows how.

Imagine a game of 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? Leonardo Barichello explains how probability holds the answer to this seemingly counterintuitive puzzle.

Euclid, known as the "Father of Geometry," developed several of modern geometry's most enduring theorems. But what can we make of his mysterious fifth postulate, the parallel postulate? Jeff Dekofsky shows us how mathematical minds have put the postulate to the test and led to larger questions of how we understand mathematical principles.

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 practice where businesses sell or book more than their capacity. So why do they do it? Nina Klietsch explains the math behind this frustrating practice.

"Parts per million" is a scientific unit of measurement that counts the number of units of one substance per one million units of another. But because it's hard to conceptualize really large numbers, it can be difficult to wrap our brains around what "one part per million" really means. Kim Preshoff (with help from 100+ animators from the TED-Ed Community) shares nine helpful ways to visualize it.
