So, let me get this right
>Co2, methane and other greenhouse gasses trap energy from the Sun inside the planet, causing weather patterns to spiral far out of control, hotter summers, colder winters, etc.
>the solution is green cars, and carbon taxes
Sorry, maybe I'm just being a retard here, but why exactly aren't we building Greenhouse Gas collectors to throw up in the sky to get all this stuff back out of the air? Why all this bureaucratic nonsense, why not just cleanup the pollution?

If you can figure out how to build a machine big enough to filter the entire atmosphere, enlighten me.
>>7805575
Because if we committed all our resources to building such an ambitious project half the planet would starve.
>>7805575
The Earth naturally builds a greenhouse effect. It's just that we humans create our own to the point where the Earth is creating a much thicker green house effect than it should. If we build machines to college the pollution, we'd probably fuck it up and destroy the entire green house effect. It'd be cheaper and more cost effect by just replaying old technology with greener technology. The Earth will eventually take care of the rest.
Is geology any good?
>>7804278
I did a soil profile once
>>7804278
With the utter collapse in oil prices and massive redundancies (Schumberger alone kicked out 39000 recently) there are armies of geologists seeing employment in a dried up market.Some no doubt seek re-specialization in other geology fields than oil exploration.
So geology is interesting but do not expect to get a job the next 15 years.

if you like the outdoors and traveling while not making much money, then yeah.
Is transhumanism ethical? And should we pursue immortality via technology? Is mind uploading possible? Discuss.
>>7803580
Why exactly would it be unethical beyond anything we're already doing today?
>>7803740
I'm not OP but there are several reasons.
You'd almost instantly create a massive class divide between people who had human enhancement technology and people who didn't. What happens when the life expectancy for an extremely small portion of humanity (who also happen to be highly influential and in control) can live much longer than an average person? What's society going to be like when 5% of the population lives to be ~300 and the rest are stuck at 60-90?
What about work that directly...

Most people here disagree but that is fine, im not looking for friends. Let me tell you why I know the system failed me. That I should be the successful one making money but let me explain
Here is the background

>Not going to graduate on time because of academic reasons about skipping/failing. Why?
>bored to death from faggot teachers and the shitty homework that i could do in my sleep and so i decide to drop out of school

Someone that's truly smart can get a B in most class while doing 0 work or studying just off tests/quizzes.
If your IQ is also that high then you should have no problem getting a high SAT score.
A 3.0 and a 2300 is enough to get into a top 50 university (although barely) which all have very smart people a "genius" like yourself could talk too.

Is psychology really a science? I mean, ofc it does not follow the idealized scientific method the way, say, Physics does, but is it close enough to a real science to deserve such title? Are ideas like projection, collective subconscious, Piaget's child development stages or Freud's sexual phases scientifically valid the way, say, the second law of thermodynamics or the inverse-square law of light are? Moreover, when it comes to practical maters (therapy, to be more precise) how effective is it?

Is anime really a science? I mean, ofc it does not follow the idealized scientific method the way, say, Physics does, but is it close enough to a real science to deserve such title? Are ideas like animu girls, anime-con clubs, Advent Child series or Rangiku's boobs scientifically valid the way, say, the second law of DeathNote or theBoku no Pico of light are? Moreover, when it comes to practical maters (Naruto, to be more precise) how effective is it?
Some psychology is science, especially modern psychology. Of course, things like Freud's sexual phases are total bullshit, which is recognized by the whole psychology community.

Can a space elevator be made out of a series of electromagnetically coupled solenoids?
Like build two things, a wide hollow tube that creates an electromagnetic field in it's center with North being up and South being down; and a smaller solid tube that generates an electromagnetic field around itself with north being down and South being up.
If you put two smaller tubes inside the bigger tubes with their ends meeting in the middle, the smaller tubes would be pushed out of the larger ones. Then you build a million of them and create a tower out of them. Would...

I kinda like this idea, but it's the same problems as a space fountain in that it's an 'active structure' which will fail spectacularly if the power fails, and it sucks like a conventional space elevator because the magnetic structures themselves could be broken if the structure develops a whip or wave down the structure.
Sounds like a better plan than the stupid ass space fountain idea.
>>7807572
Get an engineering degree and come back to me.
>>7807583
I actually got the idea while reading about the space fountain idea and thinking "why not instead of physical balls we use electricity?". Solenoids are just the first thing to come to mind since I've been reading a lot about coilgun engineering.
What about a design made entirely out of permanent magnets?
Still a structural integrity problem, but that's an issue for anything tall enough to get into space and not as shaped like a pyramid. Though I kinda doubt there's a permanent...

Do irrational numbers repeat after an infinite number of digits?
To answer that you'd first need to define what it means to be "after" an infinite number of something in a meaningful way.
>do irrational numbers never repeat?
yes
>>7807556
>Do irrational numbers repeat after an infinite number of digits?
No.
So are the two biggest problems with geothermal just the depth of the crust and having to build the infrastructure, or is there something more?
>>7807510
They also have diminishing returns on energy production because unsurprisingly, pumping water into the ground cools it, eventually.
>>7807510
Another problem is that if you have to pump the working fluid too far down to reach the heat, you'll have difficulty getting the hot fluid or vapor back up efficiently.
What advantages does a manned spaceship have over a robotic/remote operated spaceprobe when exploring targets in the solar system? Could astronauts reconfigure hardware for changed or new objectives due to new discoveries? Could they operate hardware more effeciently than a ground crew with time delay? Would there actually be scientists on board rather than engineers for maintenance?
>>7807409
none. That's why a rover reached mars but not men
putting a man on the moon was just for posterity, anything they collected could have been collected by a robot.
>>7807409
Humans are more adaptable and work quicker. Sometimes it's just easier to have a person walk over to just go do something then fuck around and try to remote control a drone to do it. A human with a bag full of tools is more versatile than a drone designed to do one or two things. Those stupid robot claws are clumsy as fuck.
They're not always worth having around, though. Most space exploration and science should be unmanned, unless it's science focused on humans themselves.

yeah but that doesn't take cost into account

Post your proofs and shit on other's proofs.
Only rule: No QED = DON'T POST
Just got to the part of my linear algebra book (p.240 and beyond) where they finally define matrix multiplication as composition of linear maps and there are a bunch of short matrix algebra proofs as problems left for the reader. Enjoy my basic logic process.

Hey /sci/ just a quick one, was wondering if it's possible for the frequency of light to synchronise with a moving object so that the latter would appear to be moving still? i.e. a buzzsaw might appear as if the blades were unmoving??
See: Monochromatic light

Light waves don't work like that

Didn't think so anon was just debunking some Alan Watts claims thank you
