Although the puzzle we started with might seem silly, the study of these structures — known as Diophantine approximations — is taken seriously and gets complicated fast. For example, it’s possible to construct so-called Liouville numbers that have an infinite irrationality exponent (endless n-good approximations for any n), but it’s a lot harder to prove that there’s any commonly-encountered number with an irrationality exponent greater than two. In the same vein, algebraic irrationals (e.g., √2) all have an irrationality measure of two, but the proof of this is fiendishly difficult and netted its discoverer the Fields Medal back in 1958.

X Chat’s standalone app isn’t the only new service X is testing this week. The company has also begun offering select users invites to its X Money payments service, which was previously being tested internally among X employees. These invites, however, were not doled out in the typical way. Instead, X owner Elon Musk worked with William Shatner (yes, the actor) to invite people into the beta in exchange for a $1,000 donation to Shatner’s charity that supports children’s and veterans’ organizations.
