Determined to understand the repeating patterns he was finding in nature, French mathematician Benoit Mandelbrot used an early form of computer imagery to produce his own versions, coining the recurring shapes fractals. This installment of the PBS series "Nova" examines the rules of these self-similar patterns and explores the ways these fascinating geometric configurations can be applied in the fields of science, medicine and the arts.

Four mathematicians are imprisoned in a shrinking room; with the walls closing in, they must try anything to escape this fatal puzzle.

NUMB3RS is a drama about FBI agent Don Eppes (Rob Morrow), who recruits his mathematical-genius brother, Charlie (David Krumholtz) to help the Bureau solve a wide range of challenging crimes in Los Angeles. The two brothers take on the most confounding criminal cases from a very distinctive perspective. Inspired by actual cases, the series depicts how the confluence of police work and mathematics provides unexpected revelations and answers to the most perplexing criminal questions. A dedicated FBI agent, Don couldn't be more different from his younger brother, Charlie, a brilliant mathematician who, since he was little, has yearned to impress his big brother. As a seasoned investigator, Don deals in hard facts and evidence, whereas Charlie, a math professor at a California university, functions in a world of mathematical probability and equations. Now, despite their disparate approaches to life, Don and Charlie are able to combine their areas of expertise and solve some killer cases.

Documentary that reveals the secret story behind one of the greatest intellectual feats of World War II, a feat that gave birth to the digital age. In 1943, a 24-year-old maths student and a GPO engineer combined to hack into Hitler's personal super-code machine - not Enigma but an even tougher system, which he called his 'secrets writer'. Their break turned the Battle of Kursk, powered the D-day landings and orchestrated the end of the conflict in Europe. But it was also to be used during the Cold War - which meant both men's achievements were hushed up and never officially recognised.

一根绳子到底有多长？这个简单到众所周知的提问，正是此次BBC地平线系列纪录片所要探讨的问题。艾伦·戴维斯将试图回答，这个很快就变成一个令人费解的古怪难题。艾伦拜访了数学界领军人物马科斯·杜·索托伊，他惊人地发现自己手中这根有限长度的绳子，在原子标度下，居然是无限长。甚至艾伦还发现，至少在理论层面上，这根短小的绳子将很可能创建一个将世界陷入末日的黑洞。一厘米将有一个新的含义，你是否会开始质疑现实生活中的构造？你测量的越精细，绳子就越长。 地平线系列纪录片是英国广播公司BBC制作的一档流行并且播放已久的科学纪录片，于1964年5月2日首播，到2013年为止已有49个系列超过1100集。本系列纪录片从历史、人文、宗教、地理、设计、艺术、生物、哲学、环保、伦理等多个方面，提供世界上最伟大科学家和哲学家一个可以交流他们看法和观点的平台，并将他们对世界的新看法引入到我们的日常知识中来的科教节目。

Is the universe actually a giant quantum computer? According to Seth Lloyd, the answer is yes. All interactions between particles in the universe, Lloyd explains, convey not only energy but also information–in other words, particles not only collide, they compute. What is the entire universe computing, ultimately? “Its own dynamical evolution,” he says. “As the computation proceeds, reality unfolds.” Programming the Universe, a wonderfully accessible book, presents an original and compelling vision of reality, revealing our world in an entirely new light.

This succinct and jargon-free introduction to effect sizes gives students and researchers the tools they need to interpret the practical significance of their results. Using a class-tested approach that includes numerous examples and step-by-step exercises, it introduces and explains three of the most important issues relating to the practical significance of research results: the reporting and interpretation of effect sizes (Part I), the analysis of statistical power (Part II), and the meta-analytic pooling of effect size estimates drawn from different studies (Part III). The book concludes with a handy list of recommendations for those actively engaged in or currently preparing research projects.
