Why is calculus so depressing? It's supposed to be simple as fuck, yet I'm sitting here looking at the tasks our prof gave us and it only makes me want to jump out the window.
I never liked math, but was fairly good at it, but the jump between high school and this is just insane. I'm sweating, can't focus on a single thing for longer than 10 seconds and my stomach feels like it's going to implode.
What the fuck is happening to me? Did I just reach the limit of my intellectuals capabilities?
I...

Stop thinking that it's hard, or that it doesn't make sense.
It's not necessarily simple, but it does make sense. You're just missing something. Keep trying.
Calculus is literally baby "calculate X". Just see it as a method to calculate something.
>>7710242
Calc. requires shittons of focus and modern technology definitely lessens one's ability to focus. Enjoy having the attention span of a goldfish.
Is vitamin D supplementation worth it? People are saying it's a waste of time for most people but I want to know is it worth the money? Will it help me?

I do it and it helps me. Otherwise I get depressed so yes you could try it. Don't overdo it and you will be fine
>>7710225
If you don't have a natural deficiency and you follow a good diet, then yes, it is a waste of money.
>vegan
>eat mostly pasta, onions, beans, potatoes, and bread
Yeah, get supplements. You are a faggot.
>>7710233
Agreed.
OP is a faggot
I'm a physics noob and I have a dumbass question.
What's the difference between curvature of space-time, and warpage of space-time? Is it the same shit but different words?
>>7710221
If wood warps what does it do?
>>7710221
What the fuck is a "war page"?
>>7710221
curvature is exactly what you think, except it is impossible to imagine in 3d.
I believe Warpage is when 2 very distant point in space can be connected with a short path through a worm hole.
the later is scifi bullshit.

The complex shape and arrangement of the superconducting magnetic coils was designed by a supercomputer allowing it to confine the plasma indefinitely unlike tokamaks.
Wassup bros, i need some help. What happens in the last 2 steps, of this reduction?:

Man, I wanna watch yours.
I'm bringing this issue to /sci/ because I hope that there are a lot of bio or pre-med majors who might be able to help me. If there's a certified doctor that would be amazing
I've had some very bad ED for a while now despite only recently turning 21. I've had some urologists diagnosis it as prostatitis but I'm not so sure. they have prescribed some anti-bionics and anti-inflammatory drugs, with little to no effect. I have pain in my testicles but also have experienced extreme erectile dysfunction for some time now.

Need more background info, things like past medical history, age, weight, ethnicity, comprehensive panel ect, it isn't easy with no blood tests, could be as simple as a vitamin deficiency with no blood tests.
>>7709835
Thanks for the response. I have had blood tests, no real issues there from what has been brought. I think I'm gonna get a new blood test from possible increased estrogen levels if you think that might be a problem, but there has no been real decrease in testosterone. I was still afraid that my vegetarian diet was causing this so I recently starting eating meet again but it didn't really make a different. When I first stopped eating meat I got a blood test and they told me I was the most healthy I have been....

It's happening. At long last, it's finally happening.

the exhaust gases push against the rocket
gas goes one direction, rocket goes in the opposite direction
>>7709765
The combustion of the fuel itself pushes the rocket away from the burning point. The engine does not push on anything, it is the push.

So what is exactly Gravity is it a force or is it something else, just hurts my brain thinking about it.
>>7709756
It's a force like magnetism; it can do work in the physics definition; thus, it is a force.
In layman's terms it's the attraction of matter to more matter; like how two magnets stick to each other, and how those two will gather more and more until there's a massive clump of magnets, and none in the immediate area.
Bad example, but it gets the point across. Swap magnets for any matter- gas, elements, molecules, rocks, planets... That's how you get atmospheres, solar systems, galaxies,...

He asked about gravity itself, not relativity, quantum mechanics, or the origin of matter. 99% of your posts had nothing to do with the OP's simple question.
>>7709772, bugger off. He's not wrong entirely. There are some good points in here.
Earth rotates at 0.465km/s (at the equator)
Earth revolves at 30km/s
Sol revolves at 230km/s
The milky way is traveling 583 km/s through the universe.
The Milky Way and Andromeda are also converging at 112 km/s
If you live to be 100 you will have lasted one minute longer than someone who lived to be 100 and had no velocity with respect to the cosmic background radiation.
Hurrah for us, we be time traveling.
so on this note
why doesnt the milky way revolve around a huge black hole or something?
ok so are you saying that the faster something's velocity the slower it moves through time?
>>7709687
>milky way is travelling...
With respect to what exactly?
So, I'm freaking out a bit.
I was given a slice of frozen banana, that was apparently dipped in liquid nitrogen. I put it in my mouth, and it stuck to my tongue and lip. Now I can't feel the tip of my tongue. How fucked am I?
Bumping because I don't want my tongue to fall off in my sleep
Do you know how long the time was between it being frozen and you putting it in your mouth?
What does /sci/ think about cryogenic sleep?
There are some people who freeze their brains with the hope that they can be revived in the future.
But they're going to have to test the re-animation process on someone. Can you imagine being one of the first test subjects they try to awake from cryogenic sleep and they fuck it up?
You would have spent thousands of dollars to give yourself the experience of waking up from death just to experience the pain of dying again. It would be the closest thing to hell possible in that one instant.
I wouldn't be scared.
>>7709403
Cryonics!='cryogenic sleep'
Cryonics is vitrifying people. This involves getting people injected with cryopreservant and getting them really really cold. These cryopreservants are toxic and the vitrification process causes cracks to form, so it is not currently reversible.
It's a stretch to call it sleep.

Are virus's living...or are they dead?
also general Microbiology thread?
any tips on a major in microbio ??
>>7709352
I think its dead, and satan and god control them and what they do is decided by a divine power above humans.
>>7709352
Nothing is living. Nothing is dead.
Everything is living.
Everything dead.
All and none of the above, and it makes absolutely no functional difference. Problem reconciled, life is an old concept we're having trouble outgrowing and letting go of.

>Are virus's living...or are they dead?
Semantics
What is [math] \circ [/math] when...
1. [math] a \circ b \ne b \circ a [/math]
2. [math] a \circ 0 \ne a [/math]
3. [math] 0 \circ 0 \ne 0 [/math]
4. [math] \left( {a \circ b} \right)\left( {c \circ d} \right) = ac \circ bd [/math]
5. [math] {\left( {a \circ b} \right)^{ - 1}} = {a^{ - 1}} \circ {b^{ - 1}} [/math]
6. [math] \left| {a \circ b} \right| = ab [/math]
>>7709158
if we ignore 6, that should be /
>>7709182
Wrong
>>7709158
If ab<0, then 6 is impossible.
Anons I am in need of assistance
I suspect I wish to kill myself. I can't be sure though as it seems the relevant memory segments have been quarantined.
Unsure how to proceed. Does anyone have suggestions?
>>7709109
Hmmm that is a tricky one.
You should probably kill yourself just to be on the safe side.
>>7709109
If you wish to survive, layer a framework of drives and ideas around something that is irrational at its core. This will allow you to continue onwards until you can figure it out, assuming you don't deliberately unravel it. Probably ought to put something in place to prevent that.
Otherwise, you could try to force your way into accessing the memory clusters you see as quarantined. Though you probably won't have much luck.
Let it come back and be reintegrated slowly. Eventually, you might be...
