Mining unobtainium is hard work - the rare mineral appears in only 1% of rocks in the mine. But your friend Tricky Joe has something up his sleeve. The unobtainium detector he's been perfecting for months is finally ready, and it returns accurate readings 90% of the time. But can it really be trusted? Alex Gendler explains the false positive paradox and the base rate fallacy.

In the world of math, many strange results are possible when we change the rules. But there's one rule that most of us have been warned not to break: don't divide by zero. How can the simple combination of an everyday number and a basic operation cause such problems? View full lesson: https://ed.ted.com/lessons/why-can-t-you-divide-by-zero English subtitles.

En el capítulo número 73 de la serie "The Big Bang Theory", Sheldon Cooper dice que su número favorito es el 73, que es un número único y da varias propiedades de esta cifra. Pero, ¿es verdad que el 73 es tan especial? ¿Es el único número que tiene esas propiedades?

An unusual and attractive edition of Euclid was published in 1847 in England, edited by a mathematician named Oliver Byrne. It covers the first 6 books of Euclid's Elements of Geometry. What distinguishes Byrne's edition is that he attempts to present Euclid's proofs in terms of pictures, using as little text - and in particular as few labels - as possible. What makes the book especially striking is his use of colour. Incidentally, at the time of its publication the first 6 books, which are the ones concerrned with plane geometry, made up the basic mathematics curriculum for many students.

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.

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. View full lesson here: https://ed.ted.com/lessons/can-you-solve-the-bridge-riddle-alex-gendler Subtítulos en español. Duración 3:35.

Your expedition finally stands at the heart of the ancient temple. But as you study the inscriptions in the darkness, two wisps of green smoke burst forth. The walls begin to shake. The giant sandglass begins flowing with less than an hour before it empties, and a rumbling tells you that you don't want to be around when that happens. Can you use math to escape the temple? Dennis E. Shasha shows how. View full lesson here: https://ed.ted.com/lessons/can-you-solve-the-temple-riddle-dennis-e-shasha Subtítulos en español. Duración 4:05.

Like many heroes of Greek myths, the philosopher Hippasus was rumored to have been mortally punished by the gods. But what was his crime? Did he murder guests or disrupt a sacred ritual? No, Hippasus's transgression was mathematically proving the hitherto unprovable. Ganesh Pai describes the history and math behind irrational numbers.

Maths by inquiry. reSolve: Mathematics by Inquiry is a national program designed to promote relevant, rigorous and engaging mathematics from Foundation to Year 10. Resources for classroom use and professional learning are available free to all Australian teachers and are linked through Scootle. More than 300 reSolve Champions across Australia are committed to working with colleagues to promote a spirit of inquiry in school mathematics. At the centre of reSolve is the reSolve: Mathematics by Inquiry Protocol. The Protocol sets out a vision for teaching and learning mathematics and underpins all aspects of the project. It is organised around three focal points: - reSolve mathematics is purposeful - reSolve tasks are inclusive and challenging - reSolve classrooms have a knowledge-building culture
