OP here,

Would be a 4.0 GPA this Spring and past Fall.
Computer Science. Pure Math interest me greatly. More so than "engineering".

Why is /sci/ so scared to discuss race and IQ? I've brought it up in a couple threads and been told to go back to /pol/ (which I don't even use).
Shouldn't we be willing to discuss things that make us uncomfortable? Hell, we tell people that there is no evidence for a God and that it's very likely they just decompose after death, all the injustices of the world and their lives not to be redeemed or balanced out in some kind of afterlife. Frankly, the idea that different races have different IQ averages doesn't even seem so cruel in comparison.
Let's have a POLITE, honest discussion please.

Sorry senpai, I thought the picture would contrast well with the default theme and draw attention.

Also I'm incredibly hungry at the moment so the picture was attractive in that mildly masochistic line of thought that I think a lot of people in STEM have.

Are there any scientists or mathematicians alive today who will or have the potential to be immortalized hundreds of years from now, like Newton, Euler, Gauss, Bohr, etc? It seems contemporary discoveries pale in comparison to the advancements made from Newton to the early 1900's, and Einstein is the most recent scientist to have legendary profundity to his name. Why were so many of the best minds concentrated in one 300 year period? I'm guessing Calculus being "new" had something to do with it. Does this mean we'll have to have another revolutionary advancement in math before the next great age of scientific advancement?

Steven Hawkings is as big as Einstein, the problem is discoveries made now are not so fundamental as they were before.

SpaceX is currently working on deploying first people-carrying voyages in year 2025.

Elon Musk believes that by year 2075 there will be over one million people living on Mars.

Are we able to build these rockets and self sustaining habitable settlements on Mars?


Is this just over-hyped brainwashing fantasy or does this actually happen to be possible?

the only thing people haven't figure out, is the economics of going to mars. The vikings, the spanish, the french, the portugese, and the english all went to the New World to get resources.

there has to be something on Mars that can be shipped back to Earth at a profit.

I'm having some trouble comprehending a problem related to pressure altimetry.

It goes that if you're flying from an area of high pressure to an area of low pressure, you will have to descend in order for the altimeter to indicate the same altitude. This makes sense since you'll have to increase the amount of air above you in order for it to exert the same amount of pressure.

The part where I'm having trouble is with respect to temperature. Going from a warm area to a cold one, I'd have to ascend to maintain the same reading on my altimeter, since now I need a shorter air column above me to exert the same pressure, as the density has now increased.

But the pic related states the opposite. I'm sure its a mistake I'm making in comprehending something, but for the life of me, I can't figure out where.

Pls help.

>Going from a warm area to a cold one, I'd have to ascend to maintain the same reading on my altimeter, since now I need a shorter air column above me to exert the same pressure, as the density has now increased

cold air shrinks and exerts less pressure dummy
>>
>>8901520
Cold air is denser, no? So wouldn't flying from high temperature to low temperature be the same as going from low pressure to high pressure?
>>
>>8901529
>Cold air is denser, no?
sure it is, but it's a gas goddammit, the hotter it gets the more it expands the more pressure it generates and it does the opposite when getting colder
notice that 0°C air is pretty fucking far away from becoming anything close to an actually dense material - liquid air needs to be -200°C and is 800 times heavier per unit of volume than normal air

Recently, I've been worrying a lot of my risk of developing schizophrenia. It seems absolutely terrifying to lose your mind in such a progressive way. Can anyone with a medical background assess my risk factor?
-18 years old
-No childhood trauma or any traumatic events
-No family history
-diagnosed with OCD at age 12
-Was on Prozac for a couple of years until a few months ago. I cut it cold turkey but I've been feeling great and no side-effects.
-Used to have anxious thoughts about a lot of things, but nothing like "people are trying to kill me", more so "What if I have cancer?" or "What is my parents die?"
-2 hallucinations ever, each when I was exhausted to the point of falling asleep (saw meteorites during a hail storm at night for about 1 second, and TV we were watching in French class went static for about 1 second only for me when I pulled an all-nighter)

Any input is greatly appreciated

Bonus question:

Say I were diagnosed, but I caught it early and received proper medication. Would a career as a scientist be ruined? As in, would I be mentally impaired?
>>
>>8900201
Sounds like your OCD is what you need to be more focused on getting under control, mate.

If you're this old and not suffering from schizophrenia, then you probably aren't going to. Source: the deepest crevice of my ass.
>>
Chronic schizophrenia usually appears by late adolescence or early adulthood. Given that you're emerging adulthood and haven't shown any real signs (disregard the hallucinations; they weren't random, they were linked with your exhaustion) I would say it's very likely that you're fine.

Scientifically speaking, should it be possible for a 10 year old boy weighing 60lbs and 4'7 tall to be twice as strong as an 18 year old man weighing 123lbs and 6'1 tall?

Well I had to supervise my 10 year old brother at the gym, I don't usually go but my dad couldn't go to with him so I had to go. He could bench 85lbs and I couldn't bench the bar (45lbs).

Then when we got home, we arm wrestled with my 2 arms versus his 1 and he won. How is this possible? Do 10 year olds have enough testosterone to be that much stronger than an 18 year old? He's not even a particularly strong looking kid, that's him in the pic attached. He looks like a nerd.

Could it be a misunderstanding? Do arm wrestles and bench presses constitute strength? Please don't roast me, stick to scientific answers. And this is not a /fit question, I don't want advice on how to improve.

He's not strong you're just weak

>>8899991
Go see a doctor, ASAP if you can barely bench 45lbs at 18 years old. you probobly need medical treatment. Might have ALS, MD, or some other degenerative disorder.
>>
>>8899997
Well it's a bit of both, but he shouldn't be THIS much stronger than me, right? Could I have an underlying condition that I don't know about or something?

The "Standard Model" is (last I checked, I'm not a physicist) the latest-and-greatest theory about the fundamental questions of WHAT the fundamental particles in the universe actually are, and what the physical forces are that act on those particles. It's the best-available picture to describe why physical shit physically happens.

That said, the people who cobbled it together have a good deal of humility, and recognize that their model is incomplete because really big stuff doesn't marry up with really little stuff, so far as the physical science people are able to tell (again, last I checked). The scientists will happily revise their paradigm (indeed they honestly expect to) once a better model is found, or once other compelling evidence of some kind is found.
