The Banach-Tarski paradox is a mathematical argument that posits that you could (theoretically) clone a sphere by using the concept of infinities. There are two types of mathematical infinities: countable, which includes all natural numbers (1, 2, and so on), and uncountable, which is the former plus decimals. By using math concepts, you could separate the sphere’s uncountable infinite points into uncountable infinite numbers of countable infinite sets, rearrange them at a set angle, and shift their positions to create a perfect clone of the original.

To curb drug deaths, communities turn to Reddit, texts and wastewater
With drug overdose deaths on the rise, authorities are attempting to curb the epidemic by tracking and sharing information in real time. In one unique effort, a nonprofit in New York City is using drug-testing equipment and stamping or marking habits of dealers to identify drug batches that may endanger users. Other approaches are also being used, such as monitoring drug-related chatter on Reddit and analyzing local wastewater for opioid and other drug levels. With the combination of these efforts, researchers hope to put a dent in the opioid crisis and reduce overdose deaths. Read full article here
