How do we overturn thermodynamics so that we can have unlimited sources of energy and continue human existence for eternity?

Shitposting online isn't going to help, go study thermodynamics and be the change you want to see.

Put a memedrive on a space windmill power turbine and have it rotate fast enough to power itself. Initial start would use solar energy.

Hey freshman in uni here I have to take a 3 quarter physics chain that includes mechanics, electro & magnetism and I forgot the last one.
The teacher is total garbage and is also just said use whatever physics book because it hasn't changed in a long time.
So which is the best one for self learning? One that makes it easy, Uni has made me realize im a brainlet

Doing an assignment for an elective chemistry course and I have to write something about a molecule of choice (silicon), any interesting things I should look into apart from the semiconductive property? Anything else it relates to with computer chips?
Cheers

Actually more of an insulator until doped with things like boron/phosphorus/antimony/etc.
Yeah, lots of uses, like in diodes/etc but to be quite honest even in just talking about the many ways of structuring the {p,n}-type crystals you could go on for hours.

Hi /sci/, brainlet coming through
What, exactly, is CRISPR?
I tried reading the wikipedia article, and didn't understand anything.
I keep seeing people talk about it on the internet. What does it mean, and what does it do?

system in the body that can insert pieces of virus infection so that it can help the immune system recognize new infections of virus already encountered which can potentially lead to the Chinese inserting specific DNA sequence into sperm/eggs
>>
>>8622451
Wait, so CRISPR isn't some kind of technology development, and it's a mechanism that's already in your body?
And this mechanism's purpose is to recognize virus "signatures", but we can repurpose it to modify DNA? How does that work?

I'm just so bored with it. As of now, it's pretty much all theoretical and dull lab work. Reading about enthalpy was interesting for about 5 minutes in highschool, but spending three hours in a lab measuring the temperature changes of boiling water cannot be more boring. Personally, I'd love to do something long (maybe even complicated) but rewarding.
I guess I should be asking when labs get more interesting? I'm currently taking general chemistry and plan on taking orgo next year.

If one were to swallow a lethal amount of sodium nitrite (99% pure), let's say six and half grams for someone who weighs around 170lbs, would they feel a burning sensation in their digestive tract? If so, how bad would it be?

Do you think we will see the Riemann hypothesis solved before 2100?
Do you even think we can see it solved in our lifetimes?
What's your opinion?

If Asians are more intelligent on average than whites, how come up until the 20th century they were technologically underdeveloped? Shouldn't they have been on top all along instead of having to catch up?

Most Asian nations are culturally conservative to the point of being a republicans wet dream. Societies that do not encourage innovation will just have people sit in their hands for fear of execution

hi. im a neet that wants to become self educated.
i want to study computer science but i also think i need some kind of working knowledge of writing prose and also math skill would be nice.
i dont mind enrolling in a local community college but are there any other resources you guys use to study subjects you're interested in?

There'll probably be a maths for computing module on the CS course, or somesuch.
I need some help with my Stats homework, as i am not very good with probability.
if i have several colors of M&M's that total 60 between the various colors, and 4 of them are yellow, what is the probability that i get at least one yellow from randomly selecting 6 M&M's?
