The research, published recently in the journal Physics of Fluids, comes at a critical time when schools and ...

 E-Mail (Vienna, March 17, 2021) When complex systems double in size, many of their parts do not. Characteristically, some aspects will grow by only about 80 percent, others by about 120 percent. The astonishing uniformity of these two growth rates is known as "scaling laws." Scaling laws are observed everywhere in the world, from biology to physical systems. They also apply to cities. Yet, while a multitude of examples show their presence, reasons for their emergence are still a matter of debate. A new publication in the Journal of The Royal Society Interface now provides a simple explana...

Mathematical analysis of COVID mortality rates in the US and Europe shows that second-wave mortality was often greatly reduced - particularly in wealthier European countries and the northeast of the US.

 E-Mail What do you do after solving the answer to life, the universe, and everything? If you're mathematicians Drew Sutherland and Andy Booker, you go for the harder problem. In 2019, Booker, at the University of Bristol, and Sutherland, principal research scientist at MIT, were the first to find the answer to 42. The number has pop culture significance as the fictional answer to "the ultimate question of life, the universe, and everything," as Douglas Adams famously penned in his novel "The Hitchhiker's Guide to the Galaxy." The question that begets 42, at least in the novel, is frustrati...
