Look at that, we could just build a railroad or highway across the ice and we could travel from America to Beijing or wherever in a fraction of the time it takes to fly.
I blame the airline industry, for keeping the world population blue-pilled in order to increase the number of people who fly inter-continental flights.

The North Pole isn't solid ice on a foundation of land like Antarctica; it's temporary, shifting sea ice that shrinks and grows with the seasons. This makes building a railroad over it impractical.
And the obvious place to link North America and Asia would be from Alaska to Russia, and the American/Russian relationship along that psuedoborder is chilly at best.
This is bait from pol
Ignore
>>7706911
Oh, and nobody fucking lives in those places, because it's too cold. There's no roads up there, which means you have no infrastructure to actually take people to the parts of America people actually live in once they'd gotten there from Russia.
And in the end, railways are so much slower than planes that it wouldn't get you there any faster, especially considering the huge detour you have to make to take the overland route.
Is Climate Change real? Is it caused by people? Can we really slow it down/stop it by switching to clean energy? Will it really have catastrophic effects? How soon?

if I ate a magnet and it went into my stomach could I use a larger magnet and run it along my body to move it up my throat and back out my mouth again?

DOCKTOR/PHYSICIAN here. i advise you to eat magnet and then make immediate appointment for mri-scan.

Lmao I'd love to see the reaction of that
1. Could a planet made entirely of water exist?
2. What would the core be like?
3. What would happen if two water planets collided? In both the initial collision and the result afterwards and during.
The core would be water, because the planet is made entirely of water.
If two planets made entirely of water collided it would become one planet made entirely of water
For some value of "entirely," yes. Obviously some other stuff is going to accrete in there. The core will be some supercritical fluid stage... hard to say exactly what its properties will be. A lot of solid material might work its way down there, though. Again, it's too hard to say. Hell, we don't even know what our own planet's core is like, much less some hypothetical one with all sorts of complicated physics that no one's ever investigated.
>>7706776
Right but what would the collision look like? I don't think the two would just have a smooth collision forming a super water planet. I mean wouldn't the forces involved create a shit ton of energy and such? Would it just be steam everywhere at the collision point. What the mass of the new planet just be A+B or would it less a shit ton of water in the process?

Is it easier to major in math and teach myself physics or major in physics and teach myself math? This goes along with some programming
Double major in theoretical physics and pure maths. Double master in theoretical physics and pure maths. Double PhD in theoretical physics and pure maths. Double post-doc in theoretical physics and pure maths.

learning physics is relatively easy if you have a phd in math
learning math is required if you have a phd in physics
physicists generally don't have the same rigor as mathematicians and have very limited if any knowledge in algebra, set theory, number theory and other less practical fields but with their excellent background in other fields of math including advanced ones like differential geometry learning math for them should be easy
>>7706789
>This is what mathematicians actually believe
Any good course in physics will require you ti take hard and rigorous mathematical subjects. You are not required to learn set theory but it complements when tou have to take topos or functional analysis. Geometry is essential to many modern areas in physics and you need a complete understanding to even attempt at a GR course.
Obviously we are not going to learn it the same way but you are implying that the subjects in physics lack...

Science doesn't get things wrong, people do. People are what say things and create higher meaning.
Science is a set of tools and a general framework. If it is returning incorrect results, either people are using it wrong, or people have "manufactured" some aspect of it wrong and it must be tweaked. These tweaks have been very few in number for quite a long time, so science getting things "wrong" in modern times is usually just arrogant and delusional people who have terrible risk assessment and error handling. In a lot of these cases, many people knew something was wrong before we even started (asbestos, tobacco, irradiated water). In others, we just rode the waves of "it's new and we know!" and "woops, we don't really know." Because people are shortsighted and stupid.
The sooner this difference is learned, the better. Fucking something up and cleaning up the damage later is absolutely not an acceptable attitude that should be condoned. It needs to be stomped out.

And that is why I study the only true science, Mathematics! No one can manufacture a result and no one can get it wrong, publish and be believed.
All you fags keep believing lies while I speak of only absolute truths.

Who here is excited to work with TensorFlow after finals are finished? I'm new to making sense of big data and you may be too but Google has open sourced an easy to use suite of tools to help learn. Check it out if you're any type of scientist.
I play on a vanilla WoW private serve that is emulated to original WoW with raids and eveything.
I'm wondering could I use tensorflow/neural networks to do a 40 man Molten Core/ BWL/ Naxx raid all done by a program learning it via wipes (trail and error)?
I would obviously have to teach DPS/Tanks/Healers how do do their roles
>>7708318
'm relatively new as well and haven't played wow but lots of rs, and i'm going to guess probably not, unless you have excellent resources and time to train them
Why is it so important to make sure tuna do not go extinct in the wild?
Seems like we could just breed all of them in farms?
It's not as if they're a keystone species in their environment and fill a very specific ecological role.
Nahh, that couldn't be it.

They're tasty
At which point math stops being just plug n' chug?
when you graduate from middle school
When you reach Teichmuller theory.

>At which point math stops being just plug n' chug?
If you're smart, it never is.
What are some good ways to keep certain species of fish, such as tuna or something, from being overfished? I'm looking for methods that involve more than just fish less. Anyone got any ideas?
Breed more?
Shitty wording of question. I mean how can we help their populations in ways different from fishing less? Such as genetic engineering or soomething
>>7706636
Breed more of them?

Here you go:
Sir Francis Galton, FRS (/ˈfrɑːnsJs ˈɡɔːltən/; 16 February 1822 – 17 January 1911) was an English Victorian statistician, progressive, polymath, sociologist, psychologist,[1][2] anthropologist, eugenicist, tropical explorer, geographer, inventor, meteorologist, proto-geneticist and psychometrician. He was knighted in 1909.
Galton produced over 340 papers and books. He also created the statistical concept of correlation and widely promoted regression toward the mean. He was the first to apply statistical methods to the study of human differences...

It's been a while /sci/. I don't have a clever one, but here you go:
>You've just visited the doctor and have been told that you have microscopic hematuria. As it turns out, microscopic hematuria occurs in 10% of all people, but in 100% of people with kidney cancer, which occurs in .0002% of all people. What are the chances, given what your doctor has told you, that you have kidney cancer?

this is at least one of the more cleverly disguised homework threads, OP, i'll give you that.
you're still a faggot, though

2 in 10,000 people have kidney cancer.
1000 in 10,000 people have microscopic hematuria, including you.
You have a 1 in 500 chance of having kidney cancer.

It does seem like that now that I think about it because the riddle is too simple. Here's a harder one for you, faggot:

Why do I perform significantly better on exams when I've had a drink or two?
>>7706306
you don't, you just think you do because drinking makes you less autistic
>>7706306
Thats a real phenomenon youre not imagining it. The second you have 1 too many it goes the complete opposite direction so reserve the drinks for study time not for exam time.
