Just leave. This is the last board where you should think that's an acceptable thing to do.

It was John Drury Clark you autist, are you new here?

depends on what the atoms are

lead

>>8060392
also depends on how fast

probably something to do with gut bacteria or olfactory conditioning so we know when a gas is from our own ass and thus not horribly dangerous

>yet most people find their own farts bearable or even smelling good?
my farts must really be toxic then

>>8060377
You think your farts smell better than your bad breath or armpits?

What the fuck is wrong with you? People actually enjoy the smell of their own farts?

>>8060311
divide the two equations

>He does math with numbers

x^5 = a/k
x^2 = b/k^2

x^3 = x^5 / x^2 = (a/k) / (b/k^2) = a*k/b

start with biomaterials, from biotech. Pretty much everything related to organic materials come from biotech related investigations.

Also food engineering has a lot to do with organic materials and is an interesting, funny and always hired area to work in, specially if you live in a processed food producer country such as murica

>>8060381
thanks for the response

my university only offers biomaterials as a high level ME course, I have none of the prereqs for it as a chem major

Right now my schedule is looking like
Advanced Organic Chemistry Lab
Materials Science
Quantum Mechanics
Pchem 2

what else should I take? i only have taken up to calc 3 do i need more maths if I'm trying to get into this?

>>8060412
Reported.

So then why do planets have moons? CHECKMATE ATHEISTS!

>>8060248
Please be kidding

But in case you're not, /saged
Also, planets don't spiral towards the sun, they fall towards it, the spinning comes from them already having tangent velocity. The sun's reaction is not chemical, its fusion. The whole "sun's gravity create's the earth's gravity" thing doesn't make any sense.

Ever stopped to think about it through?
God, we get these kinds of stoner theories all the time. People need to start considering how real physics work, at least read some introductory textbooks, rather than rely in mere intuition.
I mean, seriously, if you're going to theorize at least try and have it make sense.
>The sun needs matter to feed it so it pulls it from the environment
By virtue of what principle exactly? The issue is how come gravity exists as a large scale phenomenon with such a weak force, as in particles interacting in space with no inherent connection between each other (spooky action not whitstanding). Not like the sun is a conscious entity that says "hey I need food, come to me planeeeets!"

me fucking your mom's cunt, that degree.

Knowing that engineers only do it for the money, the one that has the highest average salary.

Therefore petroleum engineering.

Or the one with the most job openings, which is probably civil engineering.

So civil engineering if you are average, petroleum engineering if you are a genius.

>>8060108
Civil engineers are idiots that don't even know how to make a road in a straight line. Chemical engineering master race.

>>8060064
If you wanted to brute force it you can use double integration, but there are better approaches.

I would try integration in polar coordinates.

The ratio of the area of the top right square within the larger circle to the area outside is probably the same as the ratio of the smaller circle bounded by the larger circle to the area that isn't.
I say probably cause I cant be fucked to check.

You need to figure out where theorems start to break down, implications of theorems that no one thought of yet, equivalences over different branches of mathematics, etc.

Learn about methods of mathematical proofing, you either want to expand the current tools of mathematics, bridge gaps between current ones, make corrections, or simplify things. This is easier to do at the "limits" of complicated or new theorems. Essentially, if you have an idea, write it down, disregard if it's good or bad at first.

I will remind you that if you don't add any new knowledge to the field you have failed

In scenario 2 you aren't creating a closed circuit. Why would you expect anything to happen?

I'm not creating a closed circuit between ALL battery poles, no.

But if you accept the fact that the positive and the negative is seperated inside the battery, I am creating a short circuit between the positive of one, and the negative of the other.

Think of it this way:

I have 1 battery. For the sake of simplified argument, let's say the negative reservoir is in the left half, and the positive is in the right half of the battery, or something like that. So it's easy to physically differantiate between anode and cathode.

If I connect the positive pole to the negative pole, with a wire, I short out the battery. This is fact.

Chopping the battery in two before I short circuit it should make no difference, because the negative and positive are isolated from oneanother inside the battery anyway, and some extra air in between them won't change that. It's just a matter of adding extra resistence, when there is already non-conductive material between them inside the battery.

Either way, you have an excess of electrons one place, and a lack of electrons another place, and they will flow to even out and balance this when the two parts are connected. Whether the two parts are contained in the same enclosing or not.

However... If a battery is just a negative and positive part with isolation between them, so I can chop it in two like this... What's to say the two parts have to come from the same battery?

Why can't I connect the negative part of one battery, to the positive part of another battery, to achieve the same short circuit. If the batteries are identical.

It seems to me that is exactly what I would be doing when I stack batteries serially.

I'm not talking about following a loop and using Kirchoffs second law. I know how this is calculated.

I'm asking how come it psycially works that way.

Cosmologists don't have "no clue" , we know dark matter can't be hot via various probes and the Lyman alpha forest points to masses > 2 keV, that puts very tight constraints on warm dark matter.

I keep reading these anti matter/energy posts and wonder what they would have said when Brown suggested that Brownian motion was caused by little particles that you couldn't see, even with a microscope.

>typical pure science wankery with no real world worth
>he just wants to sit around doing meme math all day instead of science
>great mathematician; awful scientist
>how are we supposed to do experiments with these invisible particles? nice falsifiable "theory"

Something like this, I imagine.

Very interesting discovery! But did you find out how magnets work?
