Fireflies, Heart Beats, and the Science of Sync – Neuroscience News“The perplexing feature of these particular states is that the Rockettes in our metaphor can only see their nearest neighbor, yet manage to be coordinating with their neighbor’s neighbor,” says lead author Matthew Matheny, a research scientist at Caltech and member of the Kavli Nanoscience Institute. “We didn’t know what we were going to see,” says Matheny. “But what these experiments are telling us is that you can get complexity out of a very simple system. This was something that was hinted at before but not shown experimentally until now.” “These exotic states arising from a simple system are what we call emergent,” says Roukes. “The whole is greater than the sum of the parts.”
Fireflies, Heart Beats, and the Science of Sync – Neuroscience NewsBut it has also been observed since the early 2000s that these networks, even when consisting of identical oscillators, can spontaneously flip out of sync and evolve into complex patterns. To better understand what is going on, Roukes and colleagues began to develop networks of oscillating nanomechanical devices. They started by just connecting two, and now, in the new study, have developed an interconnected system of eight. To the team’s surprise, the eight-node system spontaneously evolved into various exotic, complex states. “This is the first experimental demonstration that these many distinct, complex states can occur in the same simple system,” says co-author James Crutchfield, a visiting associate in physics at Caltech and a professor of physics at UC Davis.
Hot streak: Finding patterns in creative career breakthroughs: International research team discovers career hot streaks occur in science, art and film -- ScienceDaily"Our findings provide a different point of view regarding individual careers," said Liu. "We found a period when an individual performs better than his normal career, and that the timing of a hot streak is random." She added, "Different from the perception [in innovation literature] that peak performance occurs in an individual's 30s or 40s, Our results suggest that individuals have equal chance to perform better even in their late careers." The researchers also wanted to learn if individuals were more productive during their hot streak periods, which last an average of four to five years. Unexpectedly, they were not. "Individuals show no detectable change in productivity during hot streaks, despite the fact that their outputs in this period are significantly better than the median, suggesting that there is an endogenous shift in individual creativity when the hot streak occurs," wrote the team in their paper.
25 is 'golden age' for the ability to make random choices: At their peak, humans outcompete many computer algorithms in generating seemingly random patterns -- ScienceDaily"This experiment is a kind of reverse Turing test for random behavior, a test of strength between algorithms and humans," says study co-author Hector Zenil. "25 is, on average, the golden age when humans best outsmart computers," adds Dr. Gauvrit. The study also demonstrated that a relatively short list of choices, say 10 hypothetical coin flips, can be used to reliably gauge randomness of human behavior. The authors are now using a similar approach to study potential connections between the ability to behave randomly and such things as cognitive decline and neurodegenerative diseases.
The word “lost” comes from the Old Norse los, meaning the disbanding of an army, and this origin suggests soldiers falling out of formation to go home, a truce with the wide world. I worry now that many people never disband their armies, never go beyond what they know. Advertising, alarmist news, technology, incessant busyness, and the design of public and private space conspire to make it so.
Zhijian and co say that players who win tend to stick with the same action while those who lose switch to the next action in a clockwise direction (where R → P → S is clockwise).This is known in game theory as a conditional response and has never been observed before in Rock-Paper-Scissors experiments. Zhijian and co speculate that this is probably because previous experiments have all been done on a much smaller scale.“This game exhibits collective cyclic motions which cannot be understood by the Nash Equilibrium concept but are successfully explained by the empirical data-inspired conditional response mechanism,” say Zhijian and co.In fact, a “win-stay, lose-shift” strategy is entirely plausible from a psychological point of view: people tend to stick with a winning strategy.
