I have a question for those of y'all that know more about physics than I do. While playing with a fidget spinner at work I noticed that while it's spinning it sort of, I dunno, resists when I move it? Like if I'm holding it horizontally while it's spinning and I try to rotate my hand so that it's spinning vertically it feels like it's resisting. Does anyone know what I'm talking about? Why does it do that? Does the phenomenon have a name?
That phenomenon is how gyroscopes work and has to do with conservation of angular momentum. Honestly it sorta breaks my head a little bit.

That's gyroscopic motion.
It'll resist angular movement to continue it's rotation.
It's neat. You'll get a similar feedback from platter hard drives when they spin up if you try to move it around in your hand.
not a doctor, not a lawyer, examples I use may not be fully researched so don't take out of context plz, don't @ me

Yeah its angular momentum, there is a physics lecture about it I saw on youtube I thought was pretty good

Moment_of_inertia is the technical term for how easy a spinning mass is to alter orentiation or speed. Also, wikipedia link for further reading, if you're interested. Angular_momentum is more specifically what you're asking about, regarding manipulation of a spinning mass.
As already stated it's why gyroscopes do how they do. Since a fidget spinner is just a stripped down and less precise gyroscope, it's why you get the feeling of resistance on your hand when changing orientation.
The most interesting trick I've seen is using a spinning bicycle tire to rotate a person sitting on a rotating chair.

I'm really glad everyone else answered that. I was going to try to, but I am not a physics person, and would have wound up making a fool of myself and confusing Darmak.

To be fair, I'm confused anyway. But I'm a highschool dropout so that's to be expected!

I always just think of it as "things travelling in a direction would like to continue traveling in that direction", and when you try and change the direction, they resist.
"I will write your name in the ruin of them. I will paint you across history in the color of their blood."
I was trying to work in a squidbillies reference, but thing's just didn't go my way.
Such is my lot in life.

Why do you think they're called gyros?
Because the only way to avoid dripping spicy garlic sauce on your shirt when you're eating one is to spin around very very fast, which ensures that any drips are flung away from you.
If I walked on the moon, while on my deathbed I'd say it was faked, but offer up no other details before I died, just to fuck with people.
Remember when Buzz punched that guy in the mouth for claiming he faked walking on the moon?
Yeah, I don't think he's gonna change his mind

Astronauts (and other space travellers regardless of what they're called by their respective countries) are, in the truest sense of a word that gets thrown around an awful lot, heroes. I hate the moon landing conspiracy or other conspiracies regarding NASA and manned space flight for that reason especially.
Like, these are people who are selflessly putting their lives on the line in the spirit of furthering the human race. Of extending our reach, boldly going and all that. They can die horribly at literally any second for like a thousand reasons while on mission, and it's all just for the sake of answering questions.
It's the noblest thing I can think of. Fuckin a, humans. We're pretty cool from time to time.
Edit: actually, space animals too. By god, this is an interspecies endeavor and the non-human contributions to space travel should be acknowledged, even if it is kinda uncomfortable. Especially because it is in fact.
You know what blows my mind? Water gaps. Rivers that run through a mountain range leaving a gorge.
Because it means that the river is older than the mountains. The gorge can't have been formed after the mountains were there, as the river would not have been able to flow up one side and down the other. So before there were mountains (or before there was those mountains) the river was doing its thing and over time the mountains formed, but they couldn't displace or stop the river. Which is pretty crazy.

Unless the pass the gorge occupies was already the lowest point, or maybe even just reached a lower point earlier, causing the water to run that way, which then made the gorge.

Edit2: Try this video:
It shows some of the stupid tricks this leads to. Don't have sound at the moment so I think this is right.

Short version!
Longer version!
Edit I think that guy has other videos up that show/explain gyroscope stuff too
It has to do with the spinning and stuff. To drunk to actually explain. But here is some further reading material https://en.m.wikipedia.org/wiki/Gyroscope

Dude has video lectures for the entirety of some MIT physics courses and is fairly interesting to watch if you're into that sort of geekery.

You obviously haven't seen me on one. :P

It’s something like gyrogiggitydoo somethin’-or-other motion, can’t think of it just now.
Better find me a sunset to walk into.
I think the effect of a spinning gyro is called shwarma.
Such is my lot in life.

Now, to be fair, it takes more than just denying it to get Buzz to punch you in the face. You have to harass him constantly and then ambush him.

Unless it's a result of snow/ice action.
A competition helping to drive development of the futuristic hyperloop transport system has been won by engineering students from Munich.
The hyperloop idea involves passengers in pods travelling at very high speeds down sealed tunnels.
The team's pod hit 457km/h (290mph) on a 1.2km (0.75 mile) test track.
Run by the SpaceX aerospace company, the competition aims to refine the technologies that could underpin the super-fast transport system.

Exposure and experience are forms of payment, right?
i'm honestly so jazzed about this
Mars Sludge is probably not toxic, and maybe full of useful macromolecules
Sarcophagus probably grants eternal life, but is incredibly cursed
It's really a tossup!
Mars all the way.
