The FBI Framed Him With Science

From Vsauce2. Find out which companies have your data and reclaim it by visiting: https://bit.ly/saymine-vsauce2 Thanks to Mine for supporting Vsauce2. When tragedy struck Madrid on March 11, 2004, the international community including the FBI rushed to help Spanish police identify the perpetrators. Some of them were too eager. A partial fingerprint match to Oregon…

Is One A Number? #shorts

From Vsauce2. What IS 1? It seems like a really stupid, obvious question, but the truth is that 1 is seriously complex. Is it even a number? Number theory pushes and pulls on 1, showing that it’s everything all at once — yet sometimes it’s powerless. Cube it, multiply, divide it… whatever you do, it’s…

Writing the Number 1 Using All 10 Digits #shorts

From Vsauce2. There are infinite ways to write the number 1 without even using a 1. But what’s the simplest way to write 1 using all 10 digits 0 to 9? You can do it with exponents, square roots, multiplication and division… really, anything goes. But the easiest, least-complicated way to get all 10 digits…

142,857 is Making Me Crazy #shorts

From Vsauce2. Of all the numbers, why is THIS one so weird? Multiply it and you’ll get the same re-arranged digits, or leave it on its own — which happens to coincide with the repeating value of 1/7… It shouldn’t be like this. Why is this happening? WHY IS 142,857 SO SPECIAL? #vsauce #education #math

This Irrational Hypotenuse Got a Man Killed #shorts

From Vsauce2. Was "alogon" unsayable because it was a mathematical Voldemort, or because the concept of irrationality was so difficult to express? Probably a little bit of both. Hippasus’s fate is a mix of legends, with some saying he was drowned at sea by the will of the Gods after discovering irrationality, and others suggesting…

2/3 Doesn’t SEEM Like a Big Deal, But It Is #shorts

From Vsauce2. Think about how people discovered fractions and what problem they were meant to solve. How do we take a thing and express its division into smaller equal parts? A lot of little somethings add up to 1… until 2/3 came along. Using a numerator that isn’t 1 doesn’t sound like much, but it…

How Egyptians Made Right Angles #shorts

From Vsauce2. The Egyptians didn’t know the Pythagorean Theorem, but they figured out a way to make perfect 3-4-5 right triangles using segments of rope. It’s so common sense, unsophisticated, and elegant that it’s an example of a proof without words AND mathematical beauty. #shorts

Making A Math Murderer

From Vsauce2. Just think of all the questions that arise when a seemingly-healthy baby dies. Was there an illness that went undetected? Was there a rare genetic defect that couldn’t possibly have been known? Are any signs of physical trauma related to the resuscitation efforts of a fragile infant, or something more sinister? Every time…

World’s Oldest Number Trick #shorts

From Vsauce2. Nicomachus wrote "Introduction to Arithmetic" nearly 2,000 years ago, but he also seems to have come up with the first mathematically-based mind blows in Syria. Given the average person’s understanding of mathematics at that time, who WOULDN’T think Nicomachus was a wizard? #shorts

The 50/50 Problem You Won’t Believe

From Vsauce2. Get the Vsauce Curiosity Box: https://www.curiositybox.com/vsauce2 Probability is one of the clearest, more straightforward disciplines within mathematics. Unfortunately, almost nothing in mathematics is murkier and more misleading than… probability. WHAT?! Belgian mathematician Maurice Kraitchik posed a simple question about wagering wallets, and in doing so he revealed a paradoxical mismatch between a raw,…

The Dumbest Logic Trap #shorts

From Vsauce2. Borrow $10, but only take $5. Then your friend will owe you $5, and you’ll owe your friend $5, and it’ll cancel out… except for the original $5 he’s already given you. RIGHT?! And that’s the $5 logic trap. #shorts

You’ll Never Win This Game

From Vsauce2. Get the Vsauce Curiosity Box: https://www.curiositybox.com/ The transitive property is ingrained in our thinking. It gives our brains a simple, straightforward way to process the world — especially with numbers. If one thing is better or more valuable than another, and that second thing is better than a third, you KNOW that the…

The No Look Dice Trick #shorts

From Vsauce2. It seems impossible that you can turn your back on a roll of three dice, then ask some math questions to determine the exact roll and exact order of the dice. But you can do this perfectly EVERY TIME and look like a super-genius when you pull it off. #shorts
