How does one work in the quantum computer industry/research field? And what sort of research is being done. Reason I ask is because I know this autistic dude who is a first year physics/astrophysics major who told me he will do his PhD in quantum computing, improve them and use them to build ai. Is this an achievable feat as a lone pHD? I'm under the impression that the issue with them is more to do with the engineering/downscaling of them, rather than the physics behind it?

99% percent of these are autists who have no idea what they are talking about.

Its commonly accepted Mercury is impossible to terraform, or there are only a few purely theoretical ideas that aren't serious to terraform it(mostly involving orbital mirrors.
However I have an idea that wouldn't involve any manmade planet sized structure BS.
The idea is to make the side that the sun doesn't face to be permanently habitable.
1. create an atmosphere so that it keeps the heat. By creating an atmosphere there will be air currents. The air currents will heat up on the side that faces the sun, and and will warm up the dark side.
2. Amplify the magnetic field. Mercury alredy has a magnetic field that can defend against the majority of the solar radiation. Its still not enough to protect a theoretical oxygen atmosphere from being blown away. Since the mercurial magnetoshere is tidally generated, we could take some small moons(<400km radius) from saturn or jupiter to orbit mercury and amplify the magnetic field to an adequate level. I admittedly have no idea when humanity will be able to do this so this will be the most difficult part.
The atmosphere should have as little CO2 as possible in be a lot thinner than Earth's so that it causes as little a greenhouse effect as possible, but should also have more oxygen to compensate for the low density. Also a thick ozone layer(much thicker than Earth's) is vital for obvious reasons.
3. create a very high albedo ring by putting a an asteroid of the appropriate material in Mercury's roche limit. The ring should have a significant tilt to shade part of the sun facing hemisphere, so that the atmosphere doesn't overheat while passing it. Additionally this shiny ring could reflect light on mercury's dark side, making it less dark.
Finally, AFAIK Mercury has a much brighter night than Earth, and with the additional lighting with a high albedo ring and moons it could be bright enough for photosynthesis. of course since Mercury is still moving, any plants that grow will be killed after 59 days at most.
So what do you think? Do you think humanity might have the technology to achieve this feat in the far future (after 500-1000 years)?
What would you add or remove from the idea?
If you think my idea is shit, Im sorry, I'm a brainlet that likes to imagine.
>create an atmosphere
pls elaborate on how the fuck you plan to accomplish this
>>8746330
The same way you create an atmosphere on mars? Crash comets. Create factories that create oxygen. Humanity will have figured it out by then.
I just finished reading Hardy's A Mathematician's Apology and I am a bit perplexed.
I want to discuss the title of that book. Why did he call it an apology? From the title it feels like he's going to say:
>Okay, I know that I did nothing good in my life for other people and instead decided to focus on finding knowledge only I and a few others care about for my own personal glory. I am sorry for that, I should have used my genius to be a doctor instead. Sorry.
But then in the book he basically justifies the attitude's of a mathematician. First he begins by debunking the notion of "using your genius for something else" by saying that men are BORN good in at most one thing and that if you do not quickly train that one and only one skill you have you will forever be some mediocre faggot working at Mc Donald's.
And I don't mention "men" for no reason. Throughout the book he says "men" in contexts where it is way more appropiate to say "person".
For example:
"Ambition has been the driving force behind nearly all the best work of the world. In particular, practically all substantial contributions to human happiness have been made by ambitions MEN."
Going back to my original point, he also justifies his own self-indulgence by saying how by studying mathematics he met the best men in the world (talking about Ramanujan and Littlewood).
He then says, right at the end, that mathematics is good because when you get to the level of abstraction he was on, math is so useless that it can't even be used for war.
So what was the point of this book? I am a student of mathematics from that perspective that book is really good as an insight into the mind of a past genius. He talks about his motivations and achievements in a relatable manner. But then why not call it "A Mathematician's Motivation"?
Other than that he also talks of the beauty of mathematics, so why not call it "A Mathematician's circlejerk"?
How is this an apology?
Read it again brainlet
>>8746251
If you are so smart then you can tell me what he was apologizing for.
>>8746240
He means apology in the Ancient Greek sense. More like "a defense."
The book is not him apologizing, but rather an argument to defend the study of mathematics.
You aren't the only one to criticize his pretension in the article

Do public schools directly cause people to be uninterested in STEM?
Any school that calls lateral numbers "imaginary numbers" is literally worthless for teaching math at the very least.
They don't help, but even at the most elite private institutions, you'll see rich brainlets who have been in private school since pre-kindergarten struggle with STEM because they are simply dumb.
>>8746102
Depends on your public school.
>ghetto school in south central LA with 95% hispanics/blacks: yes
>college-track public school in upper-class neighborhood, with full assortment of AP classes and extracurriculars, as well as rich parents donating tax credit dollars: probably not
how hard is the math up until Calculus I?
>>8746028
It's not
Literally impossible. Nobody on Earth actually understands it.
If you go to an average American school not even calculus is hard. Heck, you could even argue that undergrad isn't really that hard.
Are there any animal species, other than domesticated ones, that are newer than homo sapiens?
No, because God created man last, in his likeness.

atheists BTFO
Arguably every living species is new. The caterpillar of today is not exactly the same as the caterpillar of 1000 years ago. The sloth of today is not the sloth of 1000 years ago. etc
When a species splits into 2, it's arbitrary if you say one of them is the "same" and the other is "new". You could say either is the new one. Or both.
How come I always get constipated for 3-4 days and always shit my guts out the days. I have an healthy diet, eat a lot of fruit and veggies, drink just water and the occasional espresso. No junk food or anything. How do I solve this? Thi sis also causing me problems at work.

Alright, go look up to the text right below the banner. Notice it says, "Science & Math". Does your subject appear to fall into either of those categories? No? Well then, just what in the fuck are you doing here for?

What about the computational theory of mind?
I was bored and my friend asked me how many ways I could think of dying, and after a while I thought about something I heard, that bananas are radioactive (potassium). I did some research and couldn't find an exact result for how many bananas it'd take so I thought up a formula
"lethal = 2.5g/kg (50% weighing 75kg) aka 190 grams | 358mg to gram = 0.358g | 2.5 / 0.358 = 6.98324022346 (bananas)"
This is following multiple sources on how much potassium it'd take to be lethal, then I just added how much potassium is in one banana to the equation and I got 6.9 bananas per kg of how much you weigh
eg) 50kg x 6.9 = 345 bananas you'd have to eat in one sitting to kill you.
If I'm wrong, correct me please.
NIBBA U RONG
>>8744165
eating 345 bananas in one go wouldn't be healthy
Yes but it depends on your weight whether or not it would kill you.
Since our actions and thoughts are determined by chemical reactions do we have free will?
Yes. The brain, like all physical things, is a creation of the mind.

Define "free will".

Hey /sci/, is the quantum theory in this Chinese cartoon legit?

Does anyone else on /sci/ keep track of data in their day-to-day life? Pic related, graph of my daily electricity consumption vs the average temperature. Makes a nice example of quadratic regression.

ugh
>>8742258
>quadratic regression
>not using generalized least squares for function spaces
your stats are shit use better modeling
>>8742258
No, but it sounds neat. Like fun little hobby.
Then again, this seemingly harmless hobby sounds a lot like those people who keep live journals and have stress balls and other "neat" gadgets to help sort out their life but then end up even more stressed because know they have a daily live journal schedule to follow.
I'll do this if I ever stop having a real job, so that this doesn't interfere with my daily life.
