I can give a few examples. Computer whiz chemists are great for simulations, which are a very big part of modern chemistry as far as I know. Someone needs to write that software, and it helps to have a strong math and chemistry background.

Electrical engineers who are also very good at math are prevalent in signal processing. Things like acoustics and so on. If you throw computer knowledge in, you get DSP, which is pretty much everywhere.

This should be in the stupid question thread.

Okay, so your first rocket left fifteen minutes early, i.e. .25 hours before, so it is 9000*.25 = 2250 miles away.

So if our second rocket is traveling 1000 mph faster than our first one, it will catch up at that rate. So 2250/1000 = 2.25 = 2 hours 15 minutes.

So our second rocket catches up at 2.5 hours, translated to distance that will be 2.5*9000 = 22500 miles.

I think that in as little as 30 years a lot of people will stop thinking of themselves as human. After uploading consciousness there is no reason to remain in human form. In 7993 I find it unlikely that any humans would exist at all, but human minds certainly still would exist.

A male derives his status from the status of his mother.[39] The mother–son bond often stays strong and continues throughout life. While...

Suppose the atmosphere and all of space had the same air density as ground level on Earth (1 atm?)

Could you fly an airplane to the Moon?
>>
>>8447749
no, because the earth and the moon would quickly ignite against all that air because of friction travelling at several thousand km per second. also all that new air would generate weird gravitys, and also it could be ignited by the sun

>>8447749
Sure, but you'd have to fly in some kind of spiral since the plane would always be trying to go upwards wrt. the plane.

>>8447749

Yes, if there was air in space you could fly in it.

So anyway, I understand and can visualize how composition of shift and rotation would always have a fixed point, but how can it remain fixed, when you take a homothety of < 1 after that, unless of course you specifically choose it's center to be that fixed point?

I've seen some proof on stackexchange, but it included linear algebra which is obviously unacceptable, since it's a FUCKING ANALYSIS book - intro chapter of the first volume in fact - and you're clearly supposed to be able to solve it without linear algebra.

I got at least another question.

What's the /sci/ consensus? Anyone have an opinion on the studies and methodology attempting to quantify the quality of parenting of gay couples?
>>
>>8447650
Not good for the development of the child. A child needs to feel the polarity between mother and father in order develope properly. Furthermore, gays naturally cannot procreate so they should face not ever getting to raise children. Additionally only one of the pair can be a biological parent (at most) which causes the child to not be surrounded by his two genetic predecessors, which is reprehensible.
>>
>>8447650
It dosent fucking matter, I think people make way too much of a deal about it. The kid dosent have to grow up in an orphanage and they couple is happy to take care of them. I dont think being gay is a choice, its just something that someone is. Besides most kids who are raised by gay parents turn out just as fucked up as the rest of us. Its just propoganda.
>>
>>8447650
It probably doesn't matter and if it does, it's probably not possible to quantify. Many million children came out just fine without a father, so who gives a shit. There are also many traditional parents that fuck up their children pretty fucking bad. Humans adapt, in particular children. What it really needs is just food, shelter, limits, love, stuff like that. There is no magic happening just because one of the parents has a penis and the other not.

Study it then rehearse it a lot of times.
