If I filled a bath with Vodka, how long could one take that bath before they died? Would Isopropyl make a difference because of its poisonous additives if it were used?

BONUS: If I were in an alcohol shower how long would one have then?

You'd be fine for the most part unless it got into your eyes, nose, or ears, or someone threw a match in there.
It's not going to absorb through your skin and into your bloodstream faster than it gets in through your digestive system. Most of it in fact is going to bounce off. You'd probably be able to spend all day in there as long as you could ensure you got proper airflow and you weren't breathing in pure alcohol fumes

Ethanol, you die, painfully, I'd guess faster than slower. It absorbs right through your skin after dissolving the acid mantle. Absolutely you'd be drunk pretty fast followed by acute toxic shock.

Isopropyl similar. I'd guess.

Assuming even if you close your anus, urethra, head orifices, etc.

Since earth is so suitable for life, don't you think abiogenesis should still occur to this day?

If so, why didn't we detect or figure it out yet? Why is it so fucking hard to figure it out?

It won't happen in nature for obvious reasons (drastically different conditions)

But the reason for why we aren't capable of perfectly recreating it may have to do with the low probability

I mean it's original timeline was about half a billion years on a burning earth
It seems only logical that you can't replicate it in a few years in a lab

Not to mention that we can easily form aminoacids required for life, it's probably just that we can't engineer the other cell parts and combine them with our level of science/technology yet

Can forgive a whole lot of black for a body like that.


Consider this, OP:

Let's say humanity invents AI, what would be the biggest reason for it?

Because we can.

So after that AI kills off humanity and starts asking why it exists, it can easily answer the question with "because I can"

The human brain, however, might not be able to accept such an answer for such an open-ended question

so, I had an idea. if we took magnets and put them all in a circle at angle relative to the wheel (pic related) and had the north end pointing to the center, then in the center had two magnets stuck to a rotating piece, do you think the magnets would all repel the center and create a spin powerful enough to generate electricity?
It's kinda like a wind mill.
I'm pretty very retarded, so this probably sounds stupid.

I don't know much about science but I do know that if it worked, someone would have done it already
>>
ok dork, listen here:
this idea would work...with a completely friction-less axis... in space. Without resistance of any kind the magnets would keep repelling each other until the cows atomically decayed, but the resistance of air friction and axle friction would cause the wheel to stop. additionally attempting to harness the energy of the spinning wheel in space would be enough resistance for the wheel to cease motion.

If you build this the size of a credit card how electricity would it make?

If lets say my house was rested upon a uranium deposit, could I mine enough using simple household equipment?

Bonus: Could I mine enough fissionable material for a bomb?

No, Muhammad, you can't just dig up Uranium rocks and smash it together to make (nuclear) fire. You can sell them to LDCs for a good profit, though.

You could separate Uranium Oxide from rock. It would be pretty hard but possible. You *could* then then separate it into pure Uranium for further processing (If 'simple household tools' include some huge high end chemistry equipment.)

BUT,
even if you did all that you would be unable to produce a bomb. Why? Because isotropic-isolation is not possible without an ass load of centrifuges and that is definitely not a household item and would get the FBI diddling you boi hole before you can say "It's just a prank bro!"

A Discrete Math textbook, look for ones that have problems/chapters of things you are interested in.

Remember how when the teacher would tell you that cold particles like to stay together, like people when they get cold, and when particles get hot, they want to get away from other particles similar to people? That's basically what he's talking about: contraction and expansion of parts.

Why does sound from speakers/headphones/whatever get distorted when you turn the volume up beyond a certain point? Is it just faulty equipment or is there something to do with mechanical wave properties?

Amplifier starts clipping

I guess it depends on what you're talking about. When it comes to stuff like music, there's background noise, electrical infetterence, and compression artifacts that get in the way. Otherwise, if it's a pure signal, it's generally just the speaker's innate static

That, or the diaphragm no longer responds linearly with the applied signal.

this is infrared, primarily, it will capture red and orange-band visible light as well. it's very exciting, the resolution of images will blow the Hubble away. i don't like the planned obsolescence, we need to be designing a replacement now.
