Anyone with decent physics knowledge read about this today ? I am an ME and I kinda got blown away when I read the news as this shit has some pretty major implications behind it, like first steam engine or first computer major implications

Could you explain why its a big deal?
Well it "should" be a room temp super conductor, also requires ridiculous amount of energy to create so would make for a very powerful rocket fuel since reversing that reaction would release it all, Isp of 1700s... just those two is enough for a start
I'm skeptical but not against it. The researchers really need to produce repeatable results and need to make sure that they aren't just seeing the coating of the diamonds behaving differently at high pressures.
Amazing scientific facts about the universe.

Where are all the robots? it's 2017 and all we have are these clowns:

>Where are all the robots?
Working in industrial factories.
>>8631176
The real question is where is the demand and the funding for said robots, along with the fact that I don't think our production and all that is up to par when it comes to making the sci fi robot.

just give them wheels ffs

Is it really worth it? The only pro is that people will stay healthy for the duration of their lives.
Values would change. I don't know if it's "worth it," but the gripes you listed certainly don't matter at all.
>>8617326
>Is it really worth it?
Some would argue that the most important problem for philosophy is the inevitability of death. So yes, it is worth it.
>>8617326
>you will forget where you were born, when you were born, your parents and your whole childhood
Good.
How do I get really good at analysis?

read a book solve all problems on your own, drink coffeee and have no life. was i helpful `?
Read the section to be covered in class the night before. Try to prove the theorems without looking in the book.
Go to class and take good notes. Ask questions about the material, if you have one.
Reread the section and reorganize your notes after lecture.
Read the section again at night and keep up with your homework. Try additional problems from the book.
Go to office hours.

Hey /sci/. I had this very puzzling assignment regarding thermodynamics, it's not in English originally so I translated it as well as I could.
An empty pot is left on a stove. The cross-section of the pot is a circle. On top of the pot there is a tightly shut ceramic lid with a mass of 0,420kg. The height of the pot is 0,22m. Let’s assume that the air inside the pot is at equilibrium with the environment. How much thermal energy does the air inside the pot has to receive before air starts escaping from under the lid?
The internal energy for a two-atom gas is [math]\frac{5}{2}[/math] [math]k_B[/math] [math]T[/math] where [math]k_B[/math] is the Boltzmann constant [math]\frac{R}{Na}[/math]
The answer I got is 2,4 Joules, which sounds like a ridiculously low amount. It's the correct answer according to the assignment, but I can't wrap my head around the fact that this could be answered without knowing the radius of the pot.
Bump, did I just stump this board?
Its been a while, but if you think about the condition that gas from the inside escapes, that doesnt really specify how much gas is escaping.
So the lid really only has to be lifted enough to let a single molecule through, wich wouldnt be a lot of expansion from the gas.
>>8632975
>The answer I got is 2,4 Joules
How did you get to this?
My answer is dependent upon ambient temperature, pressure and the area of the lid.
My ability to cocentrate has been severely fucked up over the past year and I'm just always distracted in ways I wasn't before. In the past staying focused was not a challenge but now it's hard
Is there a way to fix this besides brute force?

If someone ask remotely a similar question as someone 10 years ago people will get ~extremely~ upset and comment how thread should be closed and feel good about themselves.
If someone ask what books to read on a subject mods will say this is off topic chit-chat and have thread closed.
If someone ask a really basic math question someone will "show off" and answer the questions correctly using 4-5 higher levels of sophistication than required (one the person who posed the question certainly wouldn't understand) and this commenter will get tons of "comment kudos".
If someone has questions about a response and the "comments" get more than 1-2 replies a mod will say move the discussion to "chat" (which no one uses) and comments are for short pieces.
Most SE seem to be on the insufferable side. Why is this?
dont worry, insufferable boomers who run the site will die off and the golden age of online communities will thrive
That's because stackexchange is for people who are serious about learning something and are independently capable. If you haven't exhausted obvious sources, it's not their problem.
With the internet it doesn't matter if a question was posted the day after SE was created. It's still available there. So why in the world would you want to ask the same damn question again?
The truth is, you are just too fucking lazy to find the answer yourself.
Book suggestions are just as stupid. As if there weren't a million already everywhere. As if you were going to actually read the books.
It's not their fault that you're too much of a brainlet to understand math.
It's how their site works.
You are insufferable
My friend keeps telling me there's something wrong with this mechanism, is he full of shit or am I retarded?

Why don't they just launch a cutting-edge USA spy satellite into a low parking orbit around every body in the solar system? Those things have the resolution to read a newspaper from orbit. They could take some sick-ass pictures of clouds and rocks.
Space is extremely harsh for cameras, especially high tech modern ones. The shielding necessary to protect a modern camera adds enough mass to the mission that it's just not feasible if it's not the primary mission of the craft (and it never is).
>>8632243
They should have used an iPhone. Best camera on the market.
