Rhapsody on the Proof of Pi = 4

Vi Hart examines the troll proof that pi = 4 and goes deeper into the ideas of infinigons.

If this video were supposed to be teaching you, It'd probably have to be boring and say that in one sense of limits, ** spoiler alert ** you actually do approach a circle and a line, solving the apparent paradox by saying that the invariant of length does not hold over infinity. Luckily Vi is an artist, and this is a Rhapsody, and instead of "learning," you get to actually think, if you like.

Horizon: Neanderthal

Broadcast (2003) In 1848 a strange skull was discovered on the military outpost of Gibraltar. It was undoubtedly human, but also had some of the heavy features of an ape... distinct brow ridges, and a forward projecting face. Just what was this ancient creature? And when had it lived? As more remains were discovered one thing became clear, this creature had once lived right across Europe. The remains were named Homo neanderthalensis (Neanderthal man) an ancient and primitive form of human.

The archaeological evidence revealed that the earliest Neanderthals had lived in Europe about 200,000 years ago. But then, about 30,000 years ago, they disappeared... just at the time when the first modern humans appear in Europe. The story has it that our ancestors, modern humans, spread out of Africa about 100,000 years ago with better brains and more sophisticated tools. As they spread into Neanderthal territory, they simply out-competed their primitive cousins.

But was Neanderthal really the brutish ape-man of legend, or an effective rival to our own species? And how exactly had he been driven to extinction? What could be found out about this remarkable evolution from the bones themselves? To begin the investigation a skeleton was needed, and no complete Neanderthal had ever been found.

However a reconstruction expert at The American Museum of Natural History in New York realised that it would be possible to create an entire composite skeleton from casts of partial skeletons. Gary Sawyer combined and rebuilt broken parts to create the most complete Neanderthal ever seen. This Neanderthal stood no more than 1.65m (5' 4") tall, but he had a robust and powerful build - perfect for his Ice Age environment. But would he have stood up to the cold better than modern humans?

Birth of a Great Observatory

A road was built in the middle of nowhere. ESO's first telescope took shape, at a steel company in Rotterdam. And in December 1966, the European Southern Observatory opened its first eye on the sky. Europe had embarked on a grand voyage of cosmic discovery.


John Taylor Gatto - The Reasons For Schooling

John Taylor Gatto (born December 15, 1935) is a retired American school teacher with nearly 30 years experience in the classroom, and author of several books on education. He is an activist critical of compulsory schooling, of the perceived divide between the teen years and adulthood, and of what he characterizes as the hegemonic nature of discourse on education and the education professions.

He promotes homeschooling, and specifically unschooling. Wade A. Carpenter, associate professor of education at Berry College, has called his books "scathing" and "one-sided and hyperbolic, [but] not inaccurate" and describes himself as in agreement with Gatto.

Gatto is currently working on a 3-part documentary about compulsory schooling, titled The Fourth Purpose. He says he was inspired by Ken Burns's Civil War.


SOPA Changes Name to CISPA

The latest attempt by Congress to try to regulate and control the Internet is no longer known as SOPA but CISPA: the Cyber Intelligence Sharing and Protection Act. The SOPA-like bill would give companies the power to collect information on their subscribers and hand it over to the government and all they have to do is request it. Kendall Burman, senior national security fellow for the Center for Democracy and Technology, joins Liz Wahl to talk about what this means for online freedoms.
