You'd have a hard time finding the medieval city Königsberg on any modern maps, but one particular quirk in its geography has made it one of the most famous cities in mathematics. Dan Van der Vieren explains how grappling with Königsberg's puzzling seven bridges led famous mathematician Leonhard Euler to invent a new field of mathematics.

1, 2, 3, 4, 5, 6, 7, 8, 9... and 0. With just these ten symbols, we can write any rational number imaginable. But why these particular symbols? Why ten of them? And why do we arrange them the way we do? Alessandra King gives a brief history of numerical systems.

For the majority of recorded human history, units like the weight of a grain or the length of a hand weren't exact and varied from place to place. Now, consistent measurements are such an integral part of our daily lives that it's hard to appreciate what a major accomplishment for humanity they've been. Matt Anticole traces the wild history of the metric system. English subtitles.

Dig into the mystery of Nicolas Bourbaki- one of the most influential mathematicians of all time… who never actually existed. When Nicolas Bourbaki applied to the American Mathematical Society in the 1950s, he was already one of the most influential mathematicians of his time. He'd published articles in international journals and his textbooks were required reading. Yet his application was firmly rejected for one simple reason: Nicolas Bourbaki did not exist. How is that possible? Pratik Aghor digs into the mystery. View full lesson here: https://ed.ted.com/lessons/the-greatest-mathematician-that-never-lived-pratik-aghor English subtitles. Duración 4:48.
