Does anyone here understand how mitochondria were passed on to subsequent generations in the first eukaryotes? Early on mitochondria were just vacuole enclosed aerobic bacteria so it bothers me that these were somehow able to enter other eukaryotes where the original one underwent binary fission. Now one thing I've been thinking of is how Endorifta Persephone enters tubeworm larvae by infecting it and then triggering the worm's metamorphosis, but it doesn't seem like early mitochondria worked like that based on their structure.

I think it has a lot to do with the ayy lmaos.

Well I can't argue with trips. Aliens need to stop fucking with life.

Is spread better for measuring angles than degrees and radians, /sci/?
>>8796755
spread? what spread? what spread are you TALKING about?
>>8796755
I honestly think so, but desu I haven't done too much with it.
Ultrafinitism seems like a very restrictive meme to me but I thought rational geometry could be useful.
Especially if you use it in a computer to get arbitrarily precise solutions to geometric problems.
>>8796755
There's a couple rational angle measurements.
Spread just seems to be the one he uses a lot in his videos.
Spread, cross, turn, halfturn
Half turn is my favorite btw. Just has a shitty name.

I left it 1 meter away from a window facing outside towards the sky. It gets direct sunlight about once a day for two hours. (not that it should make a difference)

Yes, that's what he just said. Are you feeling ok?
PSA:
Weed turns you into a brainlet. Just because you had some "profound" realization when you were baked af, doesn't mean it's helping you think. It's just slowing down your progress.
Study hard, wake up early, eat healthily, fap often, and do your homework in little bits spread out. You'll thank me later.

I just smoked weed a while ago
It hurts my back for some reason, and I find myself noticing things in my body I don't usually. Things like my head being too forward in posture, my hips being angled back and flexing my abs and thrusting them forward to get closer to a 90° angle, judging myself for being so alone and being much more self conscious, able to feel my body, as if I can't feel my body when I'm not high,
Does anyone understand this?
>>8795586
paranoia. welcome to schizophrenia you degenerate.
t. i smoke weed every day lmfao
waking up early is gay, sleep is good for your brain.
just exercise regularly, especially aerobics
I FAPED OFTEN... and now my dick shrinked
This girl wants me to swim in this thing with her and it looks dangerous to me but I don't want to seem like a faggot. Her assurance that it's "been obsolete for 20+ years" also seems fishy. Is she actually right and I AM being a faggot? I said yes of course but I figured you'd be able to better identify it.
I see I did a pretty shitty job of erasing one of those instagram names but fuck it. That's not the girl anyway, the girl just took a screen cap of some other girl's pic. I don't even have instagram.
swimming in the thing in the middle? I would not

You're swimming and not diving, but if there's a pressure difference the lack of diving gear will only mean you'll drown faster.
How do you get (7) from (5)?
I can't deal with these things. I wish I knew basic mathematics.
Its seems that they just develop the square, but I don't know how they get those matrix or how they come up with that one, or why they take only the real part of the second member.
>>8794862
Is this about electricity ? I see things about filters and transfer functions. If so, this is probably a thesis paper, and not very helpful, since you can solve the problems much more easily.
>>8794880
It is about DSP. I want to design a fractional delay using that method, because I know for the graphics on the next page that it is a good one.
Problem is I can't just drop the formulas on my thesis, I need to explain them. But I can't, because I am not able to understand what they are doing.
>>8794884
I'm not smart enough to help you there. I only know basic circuitry.
What is the difference between "fractional delay" and a simple temporal phase ?
Hey fags, /b/tard here
When 2 light waves cancel each other out, where does the energy go?
Comes out as something like heat if theres perfect destruction. In natural phenomena destructive interference is usually accompanied in some way by constructive interference which is where the energy can end up
>>8794190
so what, a photon comes out of thin air?
>>8794183
This is a trick question. Visible light is a very small percentage of the electromagnetic spectrum
Why there are so many women in medicine? Every class is like 75% females, I'm starting to think I have chosen a brainlets career.

Its the STEM subject that is best for women because its involves nothing but memorization.

They're going to be nurses

Will you take the anti-aging pill?

Should we fear death?
Instinctively everyone fears death. It's our biological imperative to stay alive that keeps us from killing our selves.

True, didn't answer the question though

Hello /sci/, novice programmer here.
I know that the /sci/ board is about math and science only, but i find that /sci/ would likely be the best fit to determine the superior language. Especially since you all bicker o much over minute shit like fields of science, i though that bickering could be productive for once.
With all this in mind i simply must ask:
Which programming language is the best to learn?
I'm looking for something that:
- can be easily embedded into other languages (like Lua into Java for example)
- Has the most direct compiler (least number of steps between programming language and machine language)
- Universal between the broadest range of systems (Linux, apple, windows, pi, etc.)
- Most efficient (least number of lines of code necessary to get the same stuff done, for example: java requires about 6 lines of code to print "hello world" whereas Lua requires only 1)
- anything else tht would make a progamming language helpful
get to it /sci/.
Lua obviously
>>8794559
C++ is the best to learn. Almost any other language you learn will be taught using the principles of C++. Most books about programming do it from the perspective that you have learned C++. C++ is great at learning the fundamentals of programming which would be lost on you if you took another language first.
>>8794559
Adga and Idris are the best programming languages right now.
Isabelle/HOL and Coq are the up-and-coming soon-to-be best programming languages before long (~5 years).
You know, forget about the Mars end for a minute. The gravity, the travel distance, the magnetosphere, etc.
If there's a working rocket that can carry a 400 to 500 ton payload into orbit for less than the cost of two 20 ton payloads, won't that in and of itself change everything about space exploration forever? Wouldn't it make moon exploration almost trivial and allow for the construction of a space station so massive and well-supplied that it makes the ISS look like a toy - while still having a lower price tag?
>>8788506
Forever is a long fucking time -- but yeah, a rocket that delivers payloads for a lot less money lowers the cost of putting payloads up.
>trivial
Not in and of itself, sine landing and exploration issues still remain things you need to pay attention to. But yeah, the abillity to put a lot more mass up a lot cheaper is better.
>massive space station
OK, but with the proviso that I am not sure mass is the ultimate metric for measuring the worth of a space station.
>>8788806
A larger space station always opens up more capabilities. The entire ISS is the weight of one ITS payload right now; imagine what could be built out of 10 or 20 ITS payloads
An artificial gravity centrifuge, comfortable quarters for dozens of astronauts, dedicated zero-G manufacturing facilities, a solar transmission experiment platform, etc.
Of course
Space Stations would be pretty irrelevant though, would you build a colony in the middle of the ocean ?
Maybe low earth orbit tourism would finance that though
Yea the ITS can deliver payloads to the moon, just like to Mars.
