I was curious as to how our anus/genital size/shape/color/appearance are determined. Is it through the mother or father's genes? Or, a mixture of both?
>>9065726
Your genital shape is usually determined by you Father's genes
>X
>Y
>>9065734
what about the anus?
do your dick lose sensibility to real sex if you fap daily?
How should I know?
depends on a bunch of things. if you can provide more information i might be able to give you an answer. please gibe

I should have a Y/N answer ready by tomorrow afternoon.
yes
From a scientific point of view, how can I get a hand this large?
Bench 250 lbs and jerk off at the same time.
When I cut for example paper (carbohydrat) with a sharp blade how come the blade always separates the paper BETWEEN two atoms and doesn't ever accidently split an atom and causes a nuclear explosion?
Because your blade is made of atoms and the bond strength is nowhere near strong enough in it to surpass the weak nuclear force.
>>9065698
cos the strength holding atoms together is massive and u arent gunna do that with a knife
cuz ur a fag
I think I need to learn ergodic theory but first it seems like I need to know measure theory.
so, whats the best book on measure theory?
I think Tao's book is good.

So I'm applying for graduate school, but I can't decide which track I want to go into. I'm interested in both.
>Electromagnetics/RF-microwaves
>Communications and signal processing
How should I make this decision? I really liked my electromagnetics courses, but I don't think I'm smart enough for it. I did really well in my telecommunications course, but I would like to do something with RF if possible.
I doubt you can make it when you post Homura pictures. Someone with a taste so bad like that most definitely is lost in life. Just stick with your undergrad toilet paper diploma, start wageslaving and call it a day.
Do comm and signal processing because it is more normie and also so I have less competition in EM+RF thanks
How do I learn easier, /sci/? I have memory problems, if I don't concentrate then I cannot let my subconscious accumulate information. I forget everything in 10 seconds.
Drugs: Caffeine, nicotine, amphetamines, methylphenidate, modafinil etc.
I am curious to know as well. I have just recently taken an interest in math, and hope that there is a good trick to memorizing things easier. Not being stoned all the time helps, though.
Memory pills? do they work?
Why are we forcing kids to do Algebra and upper maths? Why isn't math just optional? Why does the government force a class of 30 kids to do math hoping that one or two will actually use high maths in their careers?
>>9065625
>algebra is upper maths
idiots actually believe this.
>>9065625

It's not the government it's the schools. They are business and they want to make money. Just another "requirement" they can tack on. The rest is just "It's always been done this way so we will continue to do it this way"
On top of that let's be honest I love mathematics but 99% of the population could give a shit about algebraic topology etc. so it gives us math teachers/professors something to do other than get paid to sit around and drink coffee.
Honestly it's infuriating; I did tutoring at a college for several years, and I just couldn't fucking stand it after awhile.

>Epigenetics is Lamarkism.
No.
>>9065598
It does have a Lamarkian ring to it. Clearly it's not verbatim what Lamark said, but it's not completely Darwinian.

So smart parents have smarter and smarter children who learn more and more and have progressively smarter children, until they finally have an autist and the family line ends?
All you dogmatic logical positivist science lovers think you are intelligent and know everything about the world.
Let me tell you that you have a lot to learn. A LOT. I'm a 27 year old analytic philosopher. I draw modal logic diagrams and spend my days perfecting the art of soundness and completeness theorems. I read Naming & Necessity every day, this superior book is vastly superior to any other metaphysics on earth because of its arguments for A Posteriori Necessity. I reason using counterfactuals fluently, both using Kripke-Lewis-Stalnaker and alternative semantics.
I would like to see you try to debate me or any of my other philosopher colleges on the existence of God. You would be destroyed in seconds.

Hello /sci/
I have this engineering equestion, I'll try to phrase it as clearly as possible.
Let's say I have a gas turbine Generator, and I want to make it kind of like a Combined Cycle one.
I have a regular turbine, pic mostly related. And at the exhaust nozzle I put a reaaaaally long tube that has a conic shape, so it's diameter get's smaller as the distance increases. Now, i have a bigger tube outside of it. Concentric to the first one, and has the same pattern of change in diameter.
The inner tube is for hot combustion gases exhaust and the one outside is for cool intake air.
If the tubes are long enough(and made with a good heat exchange material) let's porpose that the heat exchabge between the intake and exhaust is 100% by the time the tube ends.
So the combustion gases temperature at the end of the looong exhaust tube is the same as the temperature of the instake air.
Assuming this and that the turbine and system are perfectly insulated, chemical combustion 100%,blah blah etc. Is it safe to say that the ONLY loss in efficiency will come from friction?
This way all the chemical energy passes "directly" to the shaft, isn't that right?
>TL;DR:
OP wants to make a super efficient CC gas turbine with a stupidly long heat exchanger so that the only loss is due to fruction. Will it work?
Hey anon.
I would just like to remind you that you are posting this question on a board where there is currently a thread of someone asking for help with pic related.
It has 56 replies.
To briefly skim over your actual question, i suppose if you make the assumption of perfect insulation, perfect combustion etc, there wouldn't be any losses.
Of course, these assumptions make the conclusion meaningless, and an arbitrarily large heat exchanger is retarded and nearly impossible to extract energy from, but sure.
>>9066214
I just wanted to know of any intrinsecal design flaws of the gas jet engine. Does a carnot-type efficiency limit apply here?
I saw that thread, It's sad.
>>9065517
I don't get it... You want to heat up the intake air?
Btw, the narrowing exhaust pipe would put backpressure on the turbine, lowering efficiency.
I read some interesting statistics on the sexual behaviour of girls in the Yanomamo tribe a few days ago.
In Yanomamo societies a girl is forbidden to have sex before menarche which usually happens at about 13-14 years of age. But the anthropologist Chagnon found that 2/3 of girls become sexually active before then at about 12 years of age.
It looks like these rules against sex before menarche are just as much social inventions as the age of consent in our societies, and just like in our societies they are often broken. It seems that girls have evolved to become sexually active slightly before menarche and the beginning of their fertility, which occurs about 2-3 years afterwards.
Why is this? What's the evolutionary purpose in being sexually active (and attractive) before becoming fertile? Is it something to do with the fact we form long-term relationships and that girls are often chosen as wives several years before they reach reproductive age? Maybe being sexually available and attractive gets male attention and incites them to compete for the females?
>What's the evolutionary purpose in being sexually active (and attractive) before becoming fertile
but anon, those girls can become pregnant
>this pedo found that being a pedo is totally normal
>why is society so broken that i cant have sex with little girls?

I have an indefinitely long list of identical tasks.
Tasks are taken from the list (in order) and added to a bucket which can contain 50 such tasks.
The tasks are taken from the bucket, to be completed, by multiple concurrent sub-processes. Each task may take a different amount of possibly-overlapping time to complete.
If my overall process is interrupted half-way through, how can I till where I "got up to"?
>>9065339
Number each task as you pull them out of the bucket starting with 1, and when you are interrupted, remember that last number.

They're nothing but peasants.
Americans import shit ton of people from Asia to do research in the USA. Everyone knows that Murricans themselves are dumb as rocks.
That guy probably spent 3+ hours searching through a highly populated area trying to find a couple people that are stupid enough to make his clip.
