A cognitive neuroscientist explains that the biological reason the image 'moves' is because the V5 (middle temporal visual area) part of your brain – devoted to motion processing – activates or fires due to the V4 part of your brain – devoted to colour and shape – becomes overstimulated. In fact, V4 neurons are saturated so much that the resting firing frequency of middle temporal neurons is interpreted as an actual sensory signal. The effect of this illusion strictly depends on several factors, namely on the receptive field sizes (the illusion changes as a function of viewing distance), V4 preference for spirals and spheres, and the middle temporal involvement in 3D and stereopsis. It is a very complex interaction, that rarely lead to suc ...

Highest average IQ is found within this ethnic group

It doesn't take a genius to recognize the vast number of contributions the people of Jewish ancestry have made in modern history. According to a 2005 scientific paper, "Natural History of Jewish Intelligence", Jews as a group inherit higher verbal and mathematical intelligence than other ethnic groups, on the basis of inherited diseases and the peculiar economic situation of Jews in the Middle Ages. Specifically, the Ashkenazi Jews - those who originated in Eastern Europe, such as Albert Einstein (left) and Carl Sagan (right) - tend to have higher intelligence than other ethnic groups; in fact, about 80% of modern Jews have Ashkenazi ancestry. One observational basis for inferring that Jews have high intelligence is their prevalence in occup ...

According to Pascal, it's healthy to believe in God

Many great minds have sought proof for God's existence. For French philosopher and scientist, Blaise Pascal, God's existence was beside the point. He conceded that nobody knows whether or not God exists, but because it's in our own best interests to behave as if He does, that's the most rational choice. This is what's known as Pascal's Wager, since it argues that it's your best bet to believe in God. (Pascal wrote of the Christian God, but this same argument could apply to any god). If God doesn't exist and you behave as if he does, you haven't lost much - just some sleep on Sunday and a few opportunities for sin. But if God does exist, you have everything to lose or gain: act as if he does exist and you spend eternity in heaven; act as if h ...

How the Turing machine works

view preview
A Turing machine is a hypothetical machine thought of by the mathematician Alan Turing in 1936. Despite its simplicity, the machine can simulate ANY computer algorithm, no matter how complicated it is. Put simply, the Turing machine isn't a physical machine, but you can imagine it as an never-ending line of tape, broken down into squares. On each of those squares is a 1, a 0, or nothing at all. The machine reads one square at a time, and depending on what it reads, it performs an action - it either erases the number and writes a new one before moving on, or simply moves on to a different square. Each of those actions, which mathematicians call a 'state', are determined by the mathematical algorithm or problem the Turing machine has been desi ...
