De quantas maneiras pode organizar um baralho de cartas?

TED - Ideas worth spreading

Um baralho. Cinquenta e duas cartas. Quantos arranjos?
Vamos colocar a questão desta forma: sempre que pega num baralho bem embaralhado, quase certamente está a segurar um arranjo de cartas que nunca existiu antes e pode não existir novamente.

Yannay Khaikin explica como os fatoriais permitem identificar o número exato (muito grande) de permutações num baralho de cartas padrão.

The Colours of Infinity

The Beauty and Power of Fractals

via GIPHY

Arthur C. Clarke presents this unusual documentary on the mathematical discovery of the Mandelbrot Set (M-Set) in the visually spectacular world of fractal geometry. This show relates the science of the M-Set to nature in a way that seems to identify the hand of God in the design of the universe itself. Dr. Mandelbrot in 1980 discovered the infinitely complex geometrical shape called the Mandelbrot Set using a very simple equation with computers and graphics.

Counting from Infinity: Yitang Zhang and the Twin Prime Conjecture

The story of a little‐known mathematician with no permanent job, working in complete isolation, and his important breakthrough towards solving the Twin Prime Conjecture

In April 2013, a lecturer at the University of New Hampshire submitted a paper to the Annals of Mathematics. Within weeks word spread – a little-known mathematician, with no permanent job, working in complete isolation had made an important breakthrough towards solving the Twin Prime Conjecture. Yitang Zhang‘s techniques for bounding the gaps between primes soon led to rapid progress by the Polymath Group, and a further innovation by James Maynard.

The film is a … Ler mais

Size Matters

Hannah Fry takes a spectacular look at the science of size by imagining a parallel world in which everything is made bigger or smaller

Professor Hannah Fry explores what life would be like if everything was either very large or very small. Could a supersized or miniaturized Earth sustain life? Could humans survive as giants or ants? Examples from nature hold the answers.

This two-part special presented by Hannah Fry shows that when it comes to the universe, size really does matter. Hannah takes the audience into a thought experiment where the size of everything can be changed to reveal why things are the … Ler mais

Every Breath We Take: Understanding Our Atmosphere

Gabrielle Walker tells the remarkable story of how we discovered that the air around us is not just empty space, it is full of hidden wonders

The air around us is not just empty space; it is an integral part of the chemistry of life. Plants are made from carbon dioxide, nitrogen nourishes the soil and oxygen gives us the energy we need to keep our hearts pumping and our brains alive. But how did we come to understand what air is made of? How did we come to know that this invisible stuff around us contains anything at all?
