How much power (in Watts or kW or MW) would this pump use to operate 24/7?
It is pumping from a segment with 1m of water into a segment of 15m water.
Obviously please don't mock the poor diagram.

You're missing the required mass flow rate.
>>9133496
>Homework
It's not homework
>req mass flow rate
Would be around 15 kg/s
>>9133501
15kg/s x 9.81m/s2 x 14m=Watts
kg*m/s2=N
N*m=J
J/s=W

Do you ever get this, /sci/? How do I stop feeling this and get back to work?
Stop giving a fuck and give your best.
>>9133327
Yes, me. My problem was that I was working full time, and did not have the time to devote to studies. When I finally got free time to study, I was too tired and bored to study, so I couldn't concentrate and would just give in to urges to play video games or drink. Ended up quitting work. Now I go to campus early every single morning, work on assignments and studying, go to classes, and when classes are over I stay on campus and study/homework until 5 or 6, then I go home. I get everything done this way. By Wednesday or Thursday usually, I have nothing on my plate and have plenty of time to fuck off.
Do you work?
>>9133385
I do not, but the school I go to is rigorous enough that I may as well be. It's routine for students to stay at the school from 9 or 10am until midnight, every night. The summer is a time of relative ease, in which I take only 2-3 classes, then get about a month off before things start up again. Problem is, due to the projects based nature of the school, there's never not work that needs to be done. Any time spent not working could be considered time wasted and future opportunities lost.

also, what books to read to get a good intuition for basic geometry? i fucked off my high school/middle school education and am not sure if starting with undergrad level geometry texts will be too abstract.

misguided, the smart verbal iqers just easymode their way through a CS degree then work at an f500 where they can talk in meetings instead of writing code.
Is latin the most /sci/ language?
If someone wanted to learn a language for purely intellectual reasons should it be latin?
You can read principia in the original language for instance. I think that's cool.

Just went outside to look at the stars, I noticed something that looked like a regular satellite gliding across the sky like I usually see on clear nights - but then i suddenly realized that it was twitching and sort of shaking up and down, very noticeably. It was all white, and moving way too fast to be an airplane. I followed it with a gaze for a while and then the light just suddenly vanished at some point in the sky so I couldnt locate it anymore, couldnt see any movement in the general direction it was going either.
What could this have been?
a satellite. the apparent vibration is the result of temperature differences in the atmosphere bending light, like heat shimmer.
>>9133184
Swamp gas or a weather balloon.
>>9133226
And the sudden disappearance is when it goes into the Earth's shadow. It had been lit by the Sun up until then.

He's hinting at some sort relativistic language paradox as if quantum behavior can be observed in etymology and words. I'm not good enough at logic or language to argue his point, but I want to be. Can someone argue for the sake of the 'a fish is not wet when submerged' guy?
>>9133121
I would start with the way that dryness and wetness are relative to each other. The existence of one concept is dependent on the other. For a fish that is submerged it's entire life, the concept of dryness is nonexistent. This makes the concept of wetness irrelevant. Therefore, fish cannot be wet.
Actually it seems like fish 'sweat' water. They're also totally coated with oils like mammals are. I don't think eukaryotic cells do very well when they're permanently submerged in water so there has to be a medium constantly between the fish and the water, leaving us to consider them 'dry'. Although we can say one can be 'wet' with oil, that would mean that humans are also constantly wet as our own skin isn't dry like a rock. So for the sake of practicality, the definition of wet must mean the subject matter being in direct contact with water.
Notwithstanding this idea that fish are dry in the water, the argument ultimately will need to address whether or not water itself is defined as 'wet'.
>quantum behavior
>in etymology
Just stop. You're not good enough at anything to realize exactly how nonsensical every part of this is.
Do we have computers that can design a protein to fold in such a way to perform a specific function? If we made a computer that could make any protein from a genome, it could design life right?
>>9133032
>He just figured out how significant we are in the grand scheme of things.
Yes. We have the power to take God's building blocks and make something new.
Now the hard part is making the simulation reality.
>>9133032
For most "specific function" we've little to no idea on how it really works, so...
We would need to have a computer able to simulate, at a molecular level, a whole human body. And then we'd need to setup the correct initial state.
Then, trials and error until we find the good protein for a task.
Then synthesis, depending on the protein it could be everything from grotesquely simple to absurdly difficult.
We're not there yet.
>>9133032
Recently I've been thinking about how memories are chemical, and therefore able to be produced or changed. It'd be nice to have more efficient, artificial brains that are immortal. Personal simulations would solve all problems. There would be no political debates, because you could choose to live in whatever reality you can imagine.
Hey /sci/, please help a brainlet out and explain me what the steps are to find the closed form of this generating function.
what's the issue, it's a_n= 2n choose n

The wind speeds they produce immense energy, why can't we make use of that for power?
>>9132756
Sporadic bursts of energy are not very useful. The electric network needs stable supplies of power, at most oscillating at daily (or rarely annual) frequency to respond to increased consumption.
Also, I very much doubt hurricanes' energy output is notable after time averaging.
Not to mention the cost for an infraestructure capable of reliably withstanding a hurricane's force while also using its energy would be too high.
>>9132756
They aren't reliable.
>can't predict the weather 7 days out
>can supposedly forecast the results of "global warming" 100 years out
are climate "scientists" serious?
Trendy trends tend to trend.
>>9132718
The actual term is climate change, it's not exactly warming. "Scientists" do not predict the exact rates of effect, or the precise time of everything happening, etc. etc. they just focus on specific factors which, combined, clearly point towards this specific change.
Weather FORECAST on the other hand has to be very precise, although the weather is one of the best examples of a chaotic physical system.
There's a huge difference between the two "predictions".
Can't predict means in a deterministic way such as with mecanincs (A.K.A. orbitak motion). Thermodynamics also can't predict many things in this sense, but your car still run, the thing is to what degree of validity is you model accurate. Weather will never tell you what will happen at your house tomorrow, but it can give good predictions to general trends in weather forecasts. Considering that global warming ia happening at a fucking global scale, your forcast doesn't need to be pin point accurate, but generate prediction of trends you can obaerve at that scale.
How far in the future do I have to travel to live forever?
>>9132445
what does that even mean.

>>9132465
>>9132466
If a person went about 0.99 C for 10 years they could potentially put themselves 70 years ahead in our future. So would 70 years be enough or do you think a person needs to travel ahead longer in order to benefit from some life extension technology or new ways of treating age related diseases.
why does adding two equations that intersect when graphed result in an equation that when graphed passes through the intersection of the two added equations.
>>9132407
Ironically, the definition of plotting a graph with two functions
>>9132407
y=f(x)
y=g(x)
for some c, y=f(c)=g(c)
adding the above equations gives
2y=f(x)+g(x)
for x=c
2y=f(c)+g(c)=2f(c)
2y=2f(c)
y=f(c)=g(c)

A couple of my friends are into meme-tier pseudo science quackery.
With one of them it's gotten to the point that I just don't want to hear about it, not at all.
How does /sci/ tell people to just shut the fuck up and keep their dumb-ass theories to themselves?
Sorry this post is vague, but I am sure you can relate.
Thanks!
>>9132354
>shut the fuck up and keep your dumb-ass theories to yourself!
Worked for me, now I have no friends
>How does /sci/ tell people to just shut the fuck up and keep their dumb-ass theories to themselves?
You misuse the word theory. It doesn't equal to "hypothesis".
See? You're clearly not any better than your pseudo science -loving friends.
I don't make friends with brainlets.
Looking for information about this trend. Silver has germicidal effects and I heard that when the US government seized a sizable amount of silverware from the public, this allowed mini epidemics. Wondering if anyone has information as the search engines seem to be scrubbed of anything in that time period.
>>9132353
Most likely to a small degree. It is used in gauze for dressing wounds too and in sutures. Colloidal silver is great for cleaning wounds (just don' t drink it.)
>>9132353

Of course. It's why you should get only brass doorknobs and brass fixtures for your bathrooms/sinks.

When did the government seize silverware?
