When someone is shot why is it not a death sentence? Like if they get shot in the gut why doesn't shit leak into their wounds and how do they live long enough for it to heal?
Why do bandages and the like not heal into wounds? Like the mending flesh doesn't slowly meld with the bandages? Or do they and that's one of the reasons you change bandages so often?
If veins are so important and carry so much blood what happens if they heal? Like if you cut your femoral or whatever and it heals but stays severed is your leg basically running on fumes from the other small veins?

What exactly are you asking for the first one? Sometimes bodily damage isn't enough to kill you, what could be simpler than that? A gut shot can totally leak shit into you, but that doesn't necessarily mean it would always be severe enough to kill you.
And bandages don't "heal into you" because they're not in you, they're just on the outside, protecting the wounded, vulnerable area from getting shit in it. Things which are totally inside you, like a bullet, will absolutely get healed around and stay inside you (which will definitely cause problems later). You change bandages because over time they themselves get dirty and this makes them fall off, or cause the wound to get dirty, defeating their purpose.
And veins generally re-attach themselves when they heal.

For the first one, I mean it seems very strange to me that people can heal from gunshot wounds
It goes through you all the way right so you've got a gaping hole in your muscles or liver or what have you, seems weird that people can survive that sort of thing long enough for it to close up

Tell me the truth about IQ, /sci/
If you have a reasonable source without questionable methods used, link it please.
(1) Do men or women have higher avg. IQ?
(2) Do women have higher verbal IQs?
(3) Why have I never truly met an intelligent woman (and I've met a lot of women). At university, outside of it, in games or social conventions.
(4) Does IQ have anything to do with the drive for knowledge? Because this too I believe is a masculine trait.

I'm starting uni in about a month, on a genetics and evolution course. I've been reading up in an attempt to be overprepared and not end up like pic related. So I was wondering if you guys had any recommendations for uni level books on genetics or engineering

You're wasting your life
This is a maths problem that I found interesting and there it is probably a solved/well known problem because it is so genral and basic.
I want to know if a chord contains the same interval several times or only has unique intervals. Every combination of 2 notes has to be considered and none of the resulting distances should be equal to eachother.
But you probably don't care about the application so here it is mathematically:
Let A be a set of natural numbers {a1, a2, ..., an}.
T(A) is the multiset of all possible differences between numbers in A with the conditions that for each pair of ai and aj:
ai > aj and i != j
This just means that we only consider each pair once and not the negative differences too and we don't consider pairs of 2 times the same element.
Essentially if you plotted A on a number line and draw and connect all points with all other ones, T(A) is the set of distances of all these bidirectional lines.
Now T(A) might have duplicate elements (which is why I said multiset) or it might night!
for A={1, 3, 7} T(A) = {2, 6, 4}, no duplicates but for A={1, 3, 7, 9} T(A) = {2, 6, 8, 4, 6, 2}, has duplicates!
So yea this is pretty much the "problem" (I dont know the proper terminology). Do what you want with it, I want to know if there is any pattern to which sets A result in a T(A) with duplicates and which don't and if there is a pattern to it.
An obvious theorem:
The cardinatlity of the multiset T(A) is n*(n-1)/2 because out of the n2 tuples we can form from A n have the same element twice (now we're at n*(n-1)) and for each tuple there is a corresponding reversed tuple but we only consider one of them (n*(n-1)/2).

Nah, you gotta restrict the problem parameters, or we can have an infinite amount of chords with intervals 1,n, for n 2 to ∞
What is the largest interval you want to take in consideration between the first and the last note? What's the largest interval possible between two notes?

>What is the largest interval you want to take in consideration between the first and the last note? What's the largest interval possible between two notes?
This thread is less about figuring out something for the application but more about doing maths with it.
Yes there are an infinite amount of chords and it is also easy to find chords without duplicated(or more) intervals (for example going 1, 10, 100, 1000) but the idea was that maybe there is a rule to which sets have duplicates and which dont without having to go through and check each difference.
A variation (which might be more simple but also harder) could be to take all differences modulo 12 (because 12 half tones in an octave)

If you are afraid of going insane chances are it wont happen. In most cases you feel ok, keep going and don't see anything wrong, you lose a great amount of circumspection.
So, if you are actually concerned, some, simple hallucinations may be the cause, I guess.
Just pop some AP's when things get bad. Shut yourself down partially for a while and then get off of them so you don't end up being a med zombie.

I am a graphic designer studying Informatics in my seconds semester but I'm still not sure if I should try to combine my future work in IT with my art or completely separate them. I fear it's possible to be a full-time IT worker and do art as hobby but nearly impossible to be a full-time artist who codes as hobby. So out of curiosity some question to all CS/IT/Informatics students here:
• why did you pick it?
• do/did you like it?
• did you finish? (if 'yes', did you do it in one go?)
• did you know how to program before?
• do you practice artistic/creative hobbies not involving programming?

Also. Dont fuck around, study your ass off. Join your schools robotic/engineering club and get involved. The kids that think college is a joke are the ones that fail out of calc 1.
