The clues have been mounting for a while. First, scientists discovered patients who had recovered from infection with Covid-19, but mysteriously didn't have any antibodies against it. Next it emerged that this might be the case for a significant number of people. Then came the finding that many of those who do develop antibodies seem to lose them again after just a few months.

How old is the Universe? For generations, people argued over whether the Universe had always existed, whether it had a beginning, or whether it was cyclical: with neither a beginning nor an end.

Tuomas Sandholm, a computer scientist at Carnegie Mellon University, is not a poker player or much of a poker fan, in fact but he is fascinated by the game for much the same reason as the great game theorist John von Neumann before him. Von Neumann, who died in 1957, viewed poker as the perfect model for human decision making, for finding the balance between skill and chance that accompanies our every choice.

"I disagree with @CDCgov on their very tough & expensive guidelines for opening schools. While they want them open, they are asking schools to do very impractical things. I will be meeting with them!!!"That, of course, is President Trump's summary of the CDC guidelines for opening schools. It ignited a predictable political back and forth fueled more by politics than facts. Let's take a minute to see what they recommended. You decide how tough they are.

Sonic booms proved to be a bust for commercial supersonic aircraft, which were banned from flying over the continental United States in 1973. But NASA's newest X-plane, the X-59 QueSST, which is expected to fly in 2021, will provide data that will allow engineers to scale down those booms, so that they sound more like muted thumps.

Nobel laureate, Steven Weinberg, at my alma mater the University of Texas at Austin, in 2017 published an article called The Trouble with Quantum Mechanics in which he laments the lack of a clear interpretation of quantum mechanics. This is, as he says, a debate that has been raging for 100 years with no signs of stopping.
