Why is pi here? And why is it squared? A geometric answer to the Basel problem

A most beautiful proof of the Basel problem, using light. Plushie pi creatures now available: More problem-driven learning: Brilliant's principles list that I referenced: Special thanks to patrons: The content here was based on a paper by Johan Wästlund Check out Mathologer's video on the many cousins of the Pythagorean theorem: On the topic of Mathologer, he also has a nice video about the Basel problem: A simple Geogebra to play around with the Inverse Pythagorean Theorem argument shown here. Some of you may be concerned about the final step here where we said the circle approaches a line. What about all the lighthouses on the far end? Well, a more careful calculation will show that the contributions from those lights become more negligible. In fact, the contributions from almost all lights become negligible. For the ambitious among you, see this paper for full details. Music by Vincent Rubinetti: ------------------ 3blue1brown is a channel about animating math, in all senses of the word animate.

The paradox of choice | Barry Schwartz Psychologist Barry Schwartz takes aim at a central tenet of western societies: freedom of choice. In Schwartz's estimation, choice has made us not freer but more paralyzed, not happier but more dissatisfied. TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world's leading thinkers and doers are invited to give the talk of their lives in 18 minutes -- including speakers such as Jill Bolte Taylor, Sir Ken Robinson, Hans Rosling, Al Gore and Arthur Benjamin. TED stands for Technology, Entertainment, and Design, and TEDTalks cover these topics as well as science, business, politics and the arts. Watch the Top 10 TEDTalks on, at

The Milky Way as You’ve Never Seen It Before – AMNH SciCafe

Fly through the galaxy with Museum astrophysicist Jackie Faherty, who takes us on a dazzling tour of new research and data visualizations made possible by recently released data from the Gaia space telescope. In April 2018, the European Space Agency’s Gaia observatory released its second data catalog, which includes the distances to over 1.3 billion stars. Faherty breaks down why this information is so revolutionary, and explains how this information is helping scientists and non-scientists alike understand the universe like never before. Listen to the full SciCafe event, including a Q&A session, by downloading the Science@AMNH podcast on iTunes, Soundcloud, or wherever you get your podcasts. This SciCafe took place on October 3, 2018. The SciCafe series is proudly sponsored by Judy and Josh Weston. #Gaia #MilkyWay #Astronomy #Astrophysics #Telescope #Satellite #SciCafe #JackieFaherty #Exoplanets #Stars *** Subscribe to our channel: Check out our full video catalog: Facebook: ‪ ‬‬‬‬‬‬‬‬‬‬‬‬‬‬ Twitter: ‪ ‬‬‬‬‬‬‬‬‬‬‬‬‬‬ Tumblr: ‪‬‬‬‬‬‬‬‬‬‬‬‬‬‬ Instagram: ‪‬‬‬‬‬‬‬‬‬‬‬‬‬‬ This video and all media incorporated herein (including text, images, and audio) are the property of the American Museum of Natural History or its licensors, all rights reserved.

This video is about Bell's Theorem, one of the most fascinating results in 20th century physics. Even though Albert Einstein (together with collaborators in the EPR Paradox paper) wanted to show that quantum mechanics must be incomplete because it was nonlocal (he didn't like "spooky action at a distance"), John Bell managed to prove that any local real hidden variable theory would have to satisfy certain simple statistical properties that quantum mechanical experiments (and the theory that describes them) violate. Since then, GHZ and others have managed to extend the theoretical work, and Alain Aspect performed the first Bell test experiment in the late 1980s.
