The square root of -1 doesn't correspond to any quantity you could count or measure directly (you can't have negative one apple, for instance)
That must be the worst explanation of complex numbers I ever read. It's not even remotely connected.
Unix time does not count elapsed seconds in real time since 1970-01-01T00:00:00, this is a common misconception.
Unix time assumes a fixed number of seconds per day. 86400. If a leap second is inserted, either end of June or end of December, the day is 86401 seconds long.
There are different implementations for how your Unix time will behave 24 hours before to 24 hours after the leap second. A timestamp might just repeat during the leap second or the system changes the length of a second in a time range around the leap second introduction to make up the difference. This is called smearing.
A simple example is the elapsed time between these two timestamps:
2016-12-31 23:59:50
2017-01-01 00:00:10
2016-12-31 23:59:60
No, the current rules are being relaxed because with the current ones, a negative leap second _might_ happen in the near future.
It did not happen yet. No negative leap second that should have been inserted was skipped.
See this chart here:
https://en.wikipedia.org/wiki/DUT1#/media/File:Leapsecond.ut...
You can see the the positive leap seconds as jumps upward once the graph reaches around -0.5 s.
We were never close to reaching +0.5 seconds with a positive trend and we are still relatively far away from that.

Imaging Atmospheric Cherenkov Telescopes, we detect optical light emitted by high energy particle Cascades in the atmosphere to observe cosmic gamma radiation.
The particles need the atmosphere to interact, Cherenkov light is only emitted in an optical medium and because it's optical light we measure we are affected by satellites. Not as strongly as optical telescopes though, because the air showers last for only tens of nanoseconds.
One would be support for ligatures
Our telescopes actually need the (or at least an) atmosphere to function.
There are some classes of observatories, which you cannot build in space but which are still affected by satellites to some degree.
This is where I usually insert that 3,000 year old Gandalf meme.

Copying my comment from the other recent thread:
The authority on the definition of SI units is very clear:
The hertz shall only be used for periodic phenomena and the becquerel shall only be used for stochastic processes in activity referred to a radionuclide
Usually, no radionuclides are involved in web requests.
Keep in mind that our current instruments are not really sensitive to most exoplanets that would be interesting for a sci-fi setting.
Current instruments are mostly good at finding large planets around small stars, we are basically blind to earth-like planets around sun-like stars.
See e.g. https://www.nobelprize.org/prizes/physics/2019/queloz/lectur...
Please don't.

Neither is usually the case for requests.
Yes, the year has pi * 1e7 seconds
1e5 / 3.14e7 ≈ 3e-3, milli, not micro
Or as Stephen Fry put it: "Nature, Nurture and Nietzsche", very fitting here.

"Most companies still do not publish Linux builds for creative software"
There, fixed it for you.
It's not like Linux is the blocker here.
Absolutely not. You could argue this for entry level lectures, but not at the PhD level. PhD is learning how to do original research, how could you separate teaching that from doing that?
Ever tried latexmk for the automation?
But this exact example is different, because the critical step of mutation is missing.
The initial line is the same, but:
a = b = random.random()
a += 1
a == b # False

Science never proves a positive.
You can only disprove.
The only way to prove a positive if there is a finite number of possibilities and you have disproven all but one. But even then, someone could conceivably come up with an alternate description that preserves the current understanding but makes additional predictions or is a simpler model making the same.
As Feyman said: "We can never know if we are right, we can only be certain if we are wrong".
If you are more into doing this locally than using a Webservice, have a look at astroplan based on astropy.
If it disagrees with experiment, it's wrong.
But on any modern CPU, clock speed won't be constant. It's not compile time constant, nor a runtime constant. Its variable over time. You'd have to record the clock speed over time and the ticks, so why not just record actual time?
Would this argument still apply if I need to store a uuidv4 anyway in the table?
And I'd likely want a unique constraint on that?
Fraktur is often associated with the German far right, because it's a mostly German thing that nationalists can hang on to.
Funnily enough, it was Goebbels who banned it and required everyone to change to Latin scripts.
The book is quite old actually, not sure if "this day and age" still applies to it
Completely new tunnel, but it will be connected to LHC, as they will use LHC to pre accelerate the particles.
Almost all accelerators built at CERN are still active and are a chain of pre-accelerator for LHC now:

They integrate with radicale since May this year for card- and caldav

WGS84 sucks for mapping a sphere.
WGS84 is not a map projection, it's a geodetic reference frame prescribing a reference ellipsoid and reference positions of ground stations.
