Ah, yes, quite a few systems use that. Iirc, when I first got into research I believe it was SPSS that have me pause (maybe STATA) when dates seemed to reference day in the 60s. It's been a while so I don't remember the specifics, but I always thought it was a neat way to handle dates.

Maybe it was 1 January 1970, the Unix epoch

You are correct, I should have said there was an atomic clock out the window that the walker looked out at.

Because of relativistic effects, from your point of view on the train you would just walk forward. But you would notice a strange effect while the trains were accelerating: ~~your atomically synchronized wristwatch~~ the clock you can see out the window has slowed down and stopped counting time. So it seems that your journey to the front of the train takes no time at all.

From someone standing on the side of the tracks catching a glimpse of you and the train as you whizz by, the front of the train is moving at light speed. You're at the back of the train completely frozen still, unable to move forward because the front of the train is moving away at light speed.

Weird things happen when you're talking about the limits of physical reality.

Sound is air vibration

Sound is not exclusive to air, it can be generalized to vibrations in any media. Whale song and dolphin echolocation are certainly sounds, and we're almost always talking about them propagating in water rather than air.

which has to travel from one place to the next

No, that isn't how sound works. In air this would be a description of wind, not sound.

just transfer kinetic energy to the adjacenct atom

This is actually a good description of how sound waves propagate.

I swear he wants to bring aristocracy to the US

He wants to further entrench the oligarchy, I think. And it seems to be working.

Housing is expensive in the USA. It's even worse in Canada.

Go look at housing prices vs incomes in the USA, then do the same for Canada. I'll let you draw your own conclusions on how people feel up here.

(Pay)checks and (account) balances?

What do you mean by moist?

They're just poking fun at a typo in your post title

What kind of nature? The answers will be very different between "flowers" and "mountainous landscapes" and "birds".

That's not what "insider trading" means, not even a little bit.
