10 January 2023 - a first time
< yesterday --

There's a first time for everything? If you knew first-order logic,
you'd say everything that happens. If you knew special relativity, you'd
say everything that happens given a known inertial reference frame. If
you knew general relativity, you'd say nothing, because some events are
intrinsically unobservable and first times cannot always be detected.
And if you knew quantum mechanics, it would get complicated. Didn't I
tell you? Only physicists are allowed to draw conclusions.
clue:
Even in special relativity, events outside your past light cone are
unobservable.
give me a clue so sweet and true
