A performance of "Mathemagic" - Arthur Benjamin Math is important to every human that has ever walked the face of the planet (and to every human that ever will). It's all around us. It's everywhere. Watch these TED Talks to learn how math is not only magical, but incredibly necessary: These Mesmerizing GIFs Illustrate the Art of Traditional Japanese Wood Joinery These Mesmerizing GIFs Illustrate the Art of Traditional Japanese Wood Joinery For centuries before the invention of screws and fasteners, Japanese craftsmen used complex, interlocking joints to connect pieces of wood for structures and beams, helping to create a uniquely Japanese wood aesthetic that can still be seen in the works of modern masters like Shigeru Ban. Up until recent times, however, these techniques were often the carefully guarded secrets of family carpentry guilds and unavailable for public knowledge. Even as the joints began to be documented in books and magazines, their 2-dimensional depictions remained difficult to visualize and not found in any one comprehensive source. That is, until a few years ago, when a young Japanese man working in automobile marketing began compiling all the wood joinery books he could get his hands on and using them to creating his own 3-dimensional, animated illustrations of their contents.

Symmetry, reality's riddle - Marcus du Sautoy Marcus du Sautoy and some colleagues at Oxford developed the “Maths in the City” web site to reveal the mathematics embedded in urban environments. Visit the Maths in the City site at to sample some of the mathematical wonders in the cities of Europe, Australia, the Middle East, Asia, and America. Add an entry spotlighting the math in your own city. Da Vinci's Vitruvian Man of math - James Earle Pico della Mirandola’s Oration on the Dignity of Man Numberphile did a great explanation of “Squaring the Circle” See James Earle's other Lesson. After Rome was destroyed, people were wary of attachment to physical beauty. As Christianity gained traction, Romans instead began to focus on the metaphysical beauty of virtue, and art began to follow suit.

The Cyclist by Julie Thissen French/Dutch product designer Julie Thissen has conceived “The Cyclist”, a series of bags designed for urban cyclists that combine practicality, elegance and safety.

With numerical data, we can try to identify patterns hidden in nature. With those patterns, we can begin to understand, predict, and perhaps ultimately control the world that surrounds us. Because data is so important to scientists and engineers, sometimes they need to worry about more than just whether they are right or wrong.

What can Schrödinger's cat teach us about quantum mechanics? - Josh Samani Quantum entanglement was first studied in 1935, in a famous paper by Albert Einstein, Boris Podolsky, and Nathan Rosen. These scientists collectively have come to be known as EPR, an acronym that derives from the first letter of each of their last names.In their paper, the authors considered a certain instance of entanglement that has since come to be known as the EPR paradox or the EPR experiment. The purpose of their paper was to use the paradox to demonstrate that quantum mechanics could not provide a complete description of reality. The term “entanglement” was not coined by EPR.Instead, it was first used by Erwin Schrodinger, one of the fathers of quantum mechanics, in a letter to Albert Einstein discussing the EPR experiment.

Mitre2 The Mitre System set and Frames. Patented by Adrian Fisher and Ed Pegg Jr. Origins Core Shapes and Supporting Shapes of The Mitre System. Patent Pending by Adrian Fisher and Ed Pegg Jr. The Infinite Hotel Paradox - Jeff Dekofsky The concept of infinity has fascinated humans since ancient times.The first known reference comes from the 5th century B.C.E. Wikipedia presents many interesting facts and applications of the concepts of both potential infinity (as used in Calculus for example) and actual infinity (as used in Set Theory). Dennis Wildfogel also created an original TED-Ed lesson on the concept of actual infinity. You can watch it here. Another great place to watch videos on infinity and other number related concepts is Numberphile.

Karatay Han was built by Seljuk Emir Celaleddin Karatay in 1240. Its plan consist of two parts. The first part, the coverde one, was built in Alaaddin Keykubad I period before 1237 and the second part, the open one, was completed in Gıyaseddin Keyhüsrev II period in 1240. How do you know you exist? - James Zucker René Descartes believed that most of what he acquired and learned came from the senses, but his senses had deceived him in the past. Can you give an example of when your senses have deceived you? Is there an experience that has made you doubt what you have seen or heard? Introduction to Arabesque In the book arts, Islimi is used to illuminate calligraphic headings and within shamsahs (little suns) which are palmettes that divide verses of text. Most famously it is interwoven with geometric patterns to create beautiful frontispieces (the first page of the Quran). Islimi is a key architectural feature, examples can be found in ornate ceramic, stone, plaster and wood carved friezes. Islimi designs are also found embellishing domestic objects such as utensils, cloths and carpets. Motifs and styles / Origins and development
