In late 2012, applied mathematician Samuel Arbesman released an intriguing little book called ‘The Half-Life of Facts’ in which he seeks to explain why a lot of the information that we all thought we knew is continually being disproven. It’s an interesting read, but the central premise should really come as no surprise. After all, science is based upon a continued quest for the refinement of knowledge, in which no theory, no matter how precious, is allowed to become immune to refutation. Still, there remains a stalwart group of pseudo scientific ‘facts’ that possess the peculiar ability to survive intact, even in the face of new contradictory evidence. So in the spirit of public service, and with the hope of helping to cleanup mankind’s collective meme pool, here’s a list of some of science’s most common misconceptions.   5) Bulls are enraged by the colour red This myth is so prevalent it’s even become the basis for a common British …

It can even do some basic components of IQ tests. The Semantic Pointer Architecture Unified Network – or SPAUN for short – was created by Chris Eliasmith and his team at the University of Waterloo. With its 2.5 million simulated neurons SPAUN is way ahead of the curve in terms of ability.  It can see with a virtual “eye” and has a virtual “arm” that it uses to draw.  This is all achieved by simulating what tasks the brain can carry out, rather than simulating the exact functioning of the brain. Other projects, such as The Blue Brain Project (TBBP), are taking a slightly more reductionist approach by attempting to simulate every single neuron in action. In 2005, TBBP had created its first simulated nerve cell. By 2008, it was running an artificial neocortical column consisting of 10,000 …
