Where does the energy in a chemical bond come from? As a biochem major(yeah I'm a filthy undergrad) I get conflicting stories from biologists and from chemists, but the quantum physical story is what I want the most if anyone can offer it.
Yes I'm retarded enlighten me.
Potential energy between bonds nuggah. In Molecular hydrogen, the electrons of one atom are attracted to the nucleus of the other all the while the two nuclei are repelling one another. It takes energy to break apart the attraction and energy is released as heat when the attraction is allowed to form.

I've been watching BattleBots, and I'm convinced that with a good team behind me, we could make something competitive on that show. Ieed a knowledgeable and creative group, with at least some CAD experience.
We can share files through AutoDesk (which is free for students). I'm in neuroscience, so I won't be able to provide a lot of specialist skills in this field, but I will take care of all administrative duties including getting us into the tournament as well as securing sponsors and/or grants. I'm willing to take on 10-20 members. Perhaps...

I remember Robot Wars in the UK, I wish I'd taken that robotics course now.

I'll suck your dick for a nickel.

it's not really necessary, as long as you have knowledge (group or individual) of kinetic physics, design, and a bit of mechanical engineering

How fast is Sunlight?

Yellow light only travels at about 0.93212c so it needs some time to get here
light doesn't have mass so it doesn't affect time

Will indenting the trailing half of an airfoil result in increased performance?
>>8175123
No, that would decrease lift by acting as a diffuser. High speed air = low pressure. Low speed air = high pressure. Energy is conserved between pressure and kinetic energy.
>>8175123
no. you don't want boundary layer separation that close to the stagnation point
Ok but how do planes fly upside down? Wouldn't air foils make them crash?
How do you go from this...
to this?

Yeah no, take your pseudo science somewhere else please.

I got this question on a quiz today. I had no idea how to do it so I just put 0
What is the answer?
>>8174962
floor(-2)+floor(--2)=0
looks good to me
I think you're right. You can always split the limit up into two parts and it look like the first is -2 and the latter is 2.
Bumpé
So is Stephen Hawking actually smart or do we just believe him because he's [spoiler]a ROBOT[/spoiler]
>>8174848
Nah , he's actually a moron
>>8174848
I just ordered a brief history of time, I will be the judge of whether or not he's smart.
>>8175024
But youve never even written a book
What right have you to criticize
what does (f(x))/(g(x)) mean?
It means you divide f(x) by g(x).
>>8174679
yeah, sure
>>8174678
"Fux the gux" obviously
What sort of math is involved in a particle (fluid) simulator?
Navier Strokes equations. It's unbelieveable how accurate they are. Almost like the physics are simulated.

lol
Are there any rational and valid arguments against "unethical" science practices? For example human experimentation on criminals that received the death penalty.
Why shouldn't we do that?
Just go to China or Russia they don't give a shit.
>>8174587
because there are no rational and valid arguments pro death penalty.
are you living in the past m8?

There are plenty you faggot.
What happens if you don't eat vegetables/fruit/legumes for a week? And neither take vitamins? Can this do any lasting damage?
>>8174535
Nothing happens.
Nothing and no.
You could eat nothing for a week and be perfectly fine.
>>8174535
dude try it out don't eat anything for a week and make a diary
Okay, /sci/, I'm trying to come up with a strategy for the classic game of 4chan Risk that's based on what would statistically be the smartest things to do.
The map of this game is pic related, and it's essentially a county map of the lower 48. As you can see, some states have bonuses. Using the number of counties each of those states has, I've determined that California has the highest bonus return of all the bonus states, offering 0.103 bonus territories per territory (the 2nd highest bonus return is Maine, at 0.0625, and the lowest is New York, at 0.0161)....

Anyone here who matriculated >25?
What's your major? How do you like it?
What did you do before uni?
I'm 27 and got into med school last year, so far it's close to the greatest thing I've ever done.

lol

What did you mean by this?
My mother was working on her AS in her 50s. I knew plenty of adults at CC who were getting degrees, one started at 52 I think, part-time. Uni is incredibly youngfag territory, diversity is a fucking joke.
Most adults

Is he right, /sci/? Is philosophy dead and done with?
>>8174352
>Bill Nye
advanced autism
>>8174352
A lot of philosophical questions are dead. In the light of evolution, it is clear there is no meaning to life. It also contradicts pretty much all religion except some forms of deism. Meanwhile, evolution shows us morality is merely socially constructed or perhaps even to some extent genetic.
If for some reason we had to replace infantry firearms with bows, would todays technology be able to make some kind of meaningful improvement to the versions historical armies used? Assume the targets would be either unarmored or use armors from pre-renaissance eras.

we can shoot supersonic bolts with explosive tips

a railgun is basically just a ballista with magnetic strings and electric springs.
