Just curious.

Does it require energy to rotate a particles axis of spin?

Posted: 24 Feb 2018 06:04 AM PST

I posted a question here a few days ago, but I didn't get my point across very well, so I'm asking a more basic question.

Whether or not a particle is measured to have spin up or down, the axis by which it "rotates" (I know it isn't actually rotating) is the same. I would assume to rotate that axis would require energy and that energy would depend on how far it has been rotated.

For example, say you have two stern-gerlack machines one after the other. The first one has the magnetic field perpendicular to the ground, the second is on a 60 degree angle to the ground. An electron is sent through the apparatus, and has it's spin measured by both setups.

Did it require energy to to change the angle that its spin was about from 90 degrees to 60 degrees? If so, was that amount of energy dependant on how many degrees it had been rotated?

Thanks!!!

Does knowledge have mass? If so, how much does it weigh?

Posted: 23 Feb 2018 04:31 PM PST

This may be a stupid question, but as I was running today, I was thinking that as we gain knowledge, we gain more information in our brain, so in a way does that knowledge have mass and does it have weight as you sort of "keep" it in your brain? Thanks! Just curious and I couldn't find similar questions that were already on this sub.

What exactly determines mucus's color?

We can see galaxies and some other objects that are millions or even billions of light years away, some of them might not exist anymore. How can we know or estimate if a star or a galaxy still exists?

Posted: 23 Feb 2018 02:09 PM PST

and second question, if it is true that we can see many objects that no longer exist, how much of the observable universe no longer exist?

Are people taking immunosuppressant drugs, for example transplant recipients, less susceptible to autoimmune diseases?

When throwing stuff, does our brain actually try to calculate how hard it has to throw for the item to land at the desired point? Or does it just estimate based on experience?

Posted: 23 Feb 2018 12:37 PM PST

I am just wondering wether the brain is secretly awesome at physics or just good at weight / strength estimation.

What makes a given smell/taste "bad" or "good". Why do we interpret them one way or the other?

Posted: 23 Feb 2018 01:27 PM PST

Even beyond personal tastes, why can we all agree, flowers smell good trash smells bad?

Does the temperature have any (noticable) effect on air resistance?

While riding my bike in cold weather, I seem to notice a bit more drag compared to biking in warmer weather. Does the increased density have noticable effect?

What happens to the jaw after permanent teeth grow in?

Posted: 23 Feb 2018 01:03 PM PST

Our permanent adult teeth grow in behind our baby teeth and push them out. What happens to the space in our jaws that used to be occupied by the adult teeth?

What are the neurological or psychological differences between the auditory hallucinations of voices, e.g., as in schizophrenia, and a persistent negative internal monologue in one's own inner voice?

I've read that when Betelgeuse explodes, it will create high levels of light at night for several days, but would a supernova on the "day side" of Earth even be visible at all?

What makes the felid species "Neofelis" so distinct from others and a member of Pantherinae?

Posted: 23 Feb 2018 02:27 PM PST

Hey!

I stumbled upon this subspecies by looking through Wikipedia for fun and was somehow surprised to find this category which only has two different types in it. The Wikipedia referals were not exactly helping me understand, so I wondered if you have some more concrete or easier to congest information.

What I have stumbled upon is that they are good climbers and rather small, so I'm even more perplexed on what makes them part of the Pantherinae tree.

Hope to gain some interesting insights!

Cheers

How does mold grow inside ice machines?

Posted: 23 Feb 2018 06:11 PM PST

How does mold subsist inside a cold ice machine, without any light or apparent source of nourishment/ chemical energy?
I tried looking this up online, but the results are all about how to clean / avoid contamination, without explaining the science behind it.
