I personally worked my whole career towards the fact, that if someone knows me and receives a PR from me, it has my name on it. This comes with a certain level of guarantee that I'm quite proud of. Quality of craftsmanship if you will.

This is one of the most valuable things I have attained.

Sure, if someone or something threw it up.
Gravity is what slows its upward movement down.
You can also see things falling horizontally. That's what satellites do. They fall towards the earth, which creates their elliptical orbit.

s/their/there

Things are different at a microscopic level, though. In quantum mechanics, between particle interactions, their is often no way to tell the direction of time.
In fact, antimatter is just matter going back in time. Or something along those lines...

There is an atmosphere on the moon, albeit a very thin one. There are even particles floating around in interstellar space. At a macroscopic level, there is pretty much no escape from friction.

At least, that is how I understand it.

If you can tell the difference by only looking at the ball, then it must be because of the effect of friction, which is what causes entropy to increase.

The entire path of the ball is controlled by gravity (ignoring friction). That's including the first part, where the ball is moving up, not just the second part where it is moving down.

Can you tell the video is played backwards, or does it look like a clip where the right kid threw the ball to the left?

Take a video of two kids slowly throwing a ball at each other. The ball follows a parabolic path. Cut out a section where the ball is moving from the left kid to the right and play it backwards.

AFAIK, it runs on Windows 10 v21H2.
@rickbrew.bsky.social ?

Agree. Seek to understand an extra layer down.

Also, when things are misinterpreted by others, be curious how they read things the other way and, instead of automatically assuming it's all on them, also learn to anticipate how someone new may absorb something, so include some helpful tips for them
