What would happen if instead of applying eugenics to humans directly, we first tested it on animals?
We do use it on animals/plants, but not to select for things we care about in ourselves. We could use selective breeding to select for high IQ in apes. If it works without any significant side-effect, then it might work on us too. And on top of that we might also create a class of high IQ monkey slaves.

covertly promoting high fertility in couples with desirable characteristics (on a holistic level, not merely intelligence, or beauty, or whatever), would yield the same benefits over time, without accidentally breeding resentment or inferiority complexes in others by tagging them as unfit. nobody needs to discourage downies or hideously ugly or chronically sick people from having kids because they are at a disadvantage anyway. everyone in the middle, laissez faire.

To be fair, Urs is doing his physics (most of it only he knows) in the presence of mathematicians who themselves work in very out-there topics. While Schulman is more of a big name, and while Baez is well-known due to his writing, all his other lads can genuinely be called on the fringe.

If i showed you a graph could you instantly know what the rule is ? How good do i have to get with them ? thank you
>>
They are foundational.
You get good at them through practice.
If you showed me a function, I could imagine the graph, yes.
You have to get good enough with picturing the graph from functions, to the point where you will be given a three variable function and have to immediately determine what type of hyperboloid or ellipsoid it is, and how to manipulate two 3D figures to create a composite of where they overlap, to build a triple integral and determine the volume of the new shape.

What's the deal with hydroelectricity generators, specifically from "Wave/Tidal" type of power.
I'm quite baffled at how there haven't already been all sorts of "Free, Clean, Infinite Energy" devices set up, instead of trying to jump through Nuclear Hoops.

But in the article here:
>https://interestingengineering.com/innovation/nanogenerators-could-produce-electricity-from-sea-waves
it looks like it works by "floating up and down"? Surely there would be better ways to draw energy from the wave than that, right?
Picrel is one example I believe.

There are a couple issues with various methods of collecting unlimited energy from the sun/the moon/the atmosphere/the earth.

First, how long it will take to pay for itself. Coal or oil power plants pay for themselves extremely quickly, but for some forms of energy it takes a long time to make the investment back so companies don't want to do it.
Next, is the cost per kW. Basically how much money it costs to make a unite of electricity. Here again, they need to compete with oil and gas which are pretty cheap. With something like offshore wave turbines you have to deal with salt water corroding everything, and plants growing on shit, and doing any maintenance work is harder if you need to go it underwater. Costs pile on. Geothermal is also costly per kW.
Another issue is how consistent it is. Solar and wind are really bad for this. If the sun just isn't out, there's no power. If the wind doesn't blow, no power. Storing power overnight is not a real solution, because you're going to have coincidence situations every year or so where it just happens to be cloudy for a whole week, especially in the winter it's an issue since the days are already shorter.

In conclusion, most "easy" ways of making power aren't used that much because they're less profitable than the alternative, and no company wants to take the less profitable choice unless they're literally force to do so by law.

>You do know that your OP pic doesn't work because you've overlooked the energy used to load the balls into the chamber against the water pressure at that level?
The point is to fill the balls with water while they AREN'T under any water pressure, because you load the balls in the chamber, seal the chamber, and then have some them roll along some railing where they some magnet "activates" the ball's lid- and then when the ball is sufficiently filled with water, some buoyant internal device is toggled to seal the ball's lid.
Then when "all" of the water from the chamber is placed inside the balls,
the balls are loaded into the "launch chamber"(depicted as the chamber with the balls filled with water),
and the launch chamber opens to let the water flood in, so the balls float up to the top;
where they are floated along a track which initiates their lid to dump the water back into the tank,
to then descend back to the ground level.

There are plenty of different systems and techniques that could be used to physically extract the "energy" produced by the balls, so there is a crazy amount of improvements that could be made, but in theory, I don't see why this couldn't be scaled up to massive powerplants.

Same with >>14859200
It could potentially be scaled up to have floating cities which can hover indefinitely without any fuel.

>it's trivial but you have to do difficult things first
the issue with 'learning' is discharging material in an orderly way and going onto the next...the point of a test is that there is a complex reputation event that ties the honesty and integrity of the testing institution a.k.a. 'school' to its judgement of your mastery of the material, namely solving some exercises and problems making use of the new definitions, lemmas, theorems, and notational conventions you just learned and have become accustomed to
when you take the test, you're essentially saying that you're discharging the material you've learned up to this point according to the grading system of the school, and that means essentially
>well, I got a B+ or an A- in that class, and that's clearly good enough, so I can forget about what I learned
It should be a mindless & mechanical process where you practice writing the contents of your mind on every available surface in your own mind simply to flex your mathematical muscles and then at the end of the semester throw everything away
>it was all trivial
and clear your mind for the next semester, putting your new playthings, your new definitions and lemmas, your new notation, all of this away in the chest of toys in your nursery

Hello /sci/ and happy friday! I'm trying to track down a study that I hear about years ago in a conversation. Apparently the participants were isolated in a room with no access to any kind of clock and were told to monitor the passage of time by their internal body clocks. The result was that participants on average adjusted to a 26 hour wake/sleep cycle. Any information would be much appreciated!

Nondisprovable conjectures is behind all cosmology. Cosmology is not science, cosmology is a belief system based on faith. Amoral jews have no misgivings about declaring their nondisprovable conjectures science because amoral jews don't have morals, they don't believe in the scientific method or any other rules, they are purely self-intersted creatures, they have no misgivings about abusing the trust of nonjews who do value the scientific method because they are purely self interested.

Certain UAP (formerly UFOs) could actually be aliens though. It can be rationalized like this: civilisations that develop technology go down a similar route, that is to say they miniaturise and mobilize their tech. The same way we can put a ventilator in ambulance that was previously so big it had to be in a building, and the ambulance vehicle itself has gotten faster, more powerful etc. If this trend is followed to it's logical conclusion, it means bulky spaceships will one day be made of materials with ridiculous (to current standards) strength weight ratios, engines, etc, and then we may one day zip around the solar system in small but powerful craft, perhaps near the limits of the laws of physics and exploring the galaxy. Going back to the UAPs, it would be like an uncontacted tribe witnessing a jet fly overhead. It's speculation to say if this is really the case for any individual event we see, but the reasoning is sound IMO.

I consider myself in the same way as someone who was in a car accident and must now relearn how to walk and hold a spoon. Math entirely stopped making sense to me once the idea of imaginary numbers was introduced and not explained beyond what was needed to solve the equations. My interest in mathematics does not involve any sort of applied sciences but is a bit more in the line of natural philosophy.
Where should I start? I imagine the education received even to the point of imaginary numbers was sub-par as well even if I didn't realize it at the time. What would be the required literature for this? I have found an interesting YouTube channel which I suspect may have good content, but the vast majority of it is entirely over my head. https://www.youtube.com/c/njwildberger
