A Universe Made of Tiny, Random Chunks: A new idea holds that the space-time that makes up our universe is inherently uncertain.

One of science’s most crucial yet underappreciated achievements is the description of the physical universe using mathematics—in particular, using continuous, smooth mathematical functions, like how a sine wave describes both light and sound. This is sometimes known as Newton’s zeroth law of motion in recognition of the fact that his famed three laws embody such functions.

 

In the early 20th century, Albert Einstein gave a profound jolt to the Newtonian universe, showing that space was both curved by mass and inherently linked to time. He called the new concept space-time. While this idea was shocking, its equations were smooth and continuous, like Newton’s.

 

But some recent findings from a small number of researchers suggest that randomness is actually inherent in space-time itself, and that Newton’s zeroth law also breaks down, on small scales.

Chimpanzees can far outperform humans in some mental tasks, including rapidly memorising and recalling numbers

Chimpanzees can far outperform humans in some mental tasks, including rapidly memorising and recalling numbers | Random Number Generator | Scoop.it

Chimpanzees can far outperform humans in some mental tasks, including rapidly memorising and recalling numbers, Japanese scientists have shown.

At the American Association for the Advancement of Science annual meeting, Tetsuro Matsuzawa, of Kyoto University’s Primate Research Institute, showed remarkable videos of chimpanzees displaying mental dexterity that would be way beyond most people.

 

The star performer among the institute’s 14 chimpanzees, a 12-year-old male called Ayumu, has learnt all the numerals from 1 to 19. Several other Kyoto chimpanzees have learnt 1 to 9.

 

When the numbers flash up in random places across a computer screen and in random order, and disappear after less than a second, the apes can point immediately to the exact locations where the numerals had been, in the correct numerical order.

 

Prof Matsuzawa said a few exceptional people, such as those with savant syndrome, might be capable of such memory feats but they are far beyond the average human brain. “One person in several thousand may be able to do this,” he said. “All the chimps I have tested can do it.”

 

Prof Matsuzawa, who combines the study of wild chimpanzees in west Africa with research using the captive colony in Kyoto, said such a good working memory – the ability to take in an accurate, detailed image of a complex scene or pattern – was an important survival tool in the wild.

 

 

For example, the apes can quickly assess and remember the distribution of edible fruit in a forest canopy. Or, when two rival bands of chimpanzees encounter one another, they can assess the strength of the rival group and decide whether to fight or flee.
