/sci/ - Science & Math

this will change the world

It's nice to have something on /sci/ that makes me smile.

You just captured the essence of economists. Which is considered a science if you can conceive that "being a dick, getting away with it, and ruling the world" is a form of discovery, practice, and speculative result.

The trick isn't the literal, but the figurative in the world of economics sciences. You have to make people believe that negative weight=reverse money sum. And then you have to convince them to act on it. As you don't want to just get stuck with a bunch of free fucking apples and trying to sell them on a street corner. That's what Mexicans do.

As an economist, I basically just told you one of the biggest secrets of our faternity. I did it in such a way you could text it to anybody, and you didn't even have to pay me.

Marxist tier: Try to start chaos and turmoil within the economy to make something out of it. Who needs to invest?! Just burn it all down, and out of the destruction and panic, you and your friends wait for the law to regain order, and then capitalize on the land, people's wants, or get something out of it. Sort of like insurance fraud, but on a much bigger scale. Even Illuminati tier is scared of you, and that's why we had the cold war and broke up the Soviet Union. Nowadays, these guys are pretty much indistinguishable from Mexican tier, and what we "call" communists are just Kenyesian tier.
Illuminati tier: Privatized banking systems that can control multiple country's finances and just labeling "treason and national security threat" won't do shit anymore.

Kenyesian tier: Nationalization of all goods and services. Or at the very least a government big enough to control who succeeds and who fails and reward those who suck government dick and that way your people can control the global economy and not have to answer to the jewish bankers. (For a while... Iran your time is running out.)

>>4476896
Ayn Rand tier: Investing early in life in land, and property. Renting out houses, selling off chunks of lands to giant companies for a bargain. Blow it all out your ass about how you're so smart and commoners should be lucky you don't murder them outright while you are a shit manager and a shit person.

Mexican tier: Take advantage of the system, get on welfare, steal, do whatever you can to survive and not have to work so hard.

Amerifat tier: Work hard, don't lie or cheat, accept it when prices go up, bills pile up, and you get kicked out of places. Durp all your life with credit card debt, healthcare expenses, are completely burned out by fifty with aches, pains, depression, and a numbed down brain who can only mutter "yes sir..." in the face of anyone with a remote hint of self preservation. Wait to die.

(Be nice if there wasn't so many "field too long" accusations. What is this, twitter?!)

get the fuck out there's no seriousness here

>>4476934
someone explain why this wouldn't work in the next fifteen minutes or I'm building it.

>>4476934
The pressure required to maintain the seal on the water at the bottom has to be at least as strong as the pressure difference allowing the hollow balls to raise.

>>4476992
friction, and the fact that the weight of the water would not allow the seal to open to let the balls through.
i really hope you don't believe me, because i want to see you build it.

but i was wondering: if we had magic barriers that kept the column of water in place but let the balls through effortlessly, removed the generator and all friction in the bearings, would we have a perpetual motion machine?

>>4477004
Not really as the 'magic barriers' would be a source of energy through the proxy; water.

>>4477004
>weight of the water blah blah blah
mutlple layers of waters with multiple seals that don't touch each other
not using ping pong balls, something much bigger

two possible solutions for water weight issue.

also, friction should be considered just above 0 when considering perpetual motion machines, like this one. imagine I use a ridiculously good material for everything.

>>4476992
>someone explain why this wouldn't work in the next fifteen minutes or I'm wasting my time
Have fun.

>>4477013
but it would be perpetually in motion?

>>4477019
i have no idea what you're on about

>>4477019
Multiple seals makes it harder for the balls to move, not easier.

>>4477041
The water pours out of bottom because the other water is higher.

>>4477041
>>4477041
The weight of the water on the right would cause the left to overflow. Seriously, I know children who could spot that.

>>4477053
>>4477051
then you make one opening bigger.

>>4477063
in which case the pressure changes and the balls can't move

>>4477063
What's the size of the opening have to do with anything?

>>4477073
>put $20 in the box, lose $20
>give the other guy $30 for a $40 box
>net loss of $10

Work this one out

>>4477073
>lose $20
>lose $30, gain $40
net loss of $10

Could the capillary effect be used to create something like this? With a million tiny pipes in the shape of an upside down cane, dripping on something?

>>4477091

No.

>>4477073
Say both have $100

They put $20 each in the box.

A: $80
B: $80

A sells the box to B for $30

A: $110
B: $50

Say they split the money in the box again

A: $130
B: $70

Uh... A guy seems to be clever.

>>4477091
It could if you were able to channel the dripping action onto a lever or something and then back into a resovoir at the bottom of the cappilary tubes but unless this was done on a very large scale it would be quite slow

>>4476794
Why wouldn't this work again?

>>4477134
The car is pulling the magnet to the left as much as the magnet is pulling the car to the right. Net force: 0

>>4477119
The same force that brings water up the tube keeps it *in* the tube. It doesn't work.

>>4477226

>implying the speed of sound is infinite

>>4477226
this is assuming that the stick is perfectly rigid, which it's not.

actually, something that is extremely thin compared to it's length would act like a spring.

>>4477226
Couldn't we make something like that work? Like an interstellar telegraph?

>>4477295

not sure if serious...

>>4477345
Why couldn't it work?

>>4477353
When you push on a stick the other end does not move instantaneously. The force moves through the stick at the speed of sound through the materiel.

>>4478426
Ok now someone please explain this one or I'M going to build it.

>>4478439
Magnetism is a conserved force. The energy produced by allowing two magnets to move a meter together is equal to the energy required to move them a meter apart; plus energy lost due to friction. There is no net gain of energy from any machine like that.

>>4478447
FUCK THIS UNIVERSE AND IT'S LAWS.

>>4476882
It's a decent thingy you wrote

The metal is pulling on the magnet with the same strength that the magnet is pulling on the metal.

Citation: Newton's Third Law

>>4478459

wont work because its not scalable. the action of holding water in place in a straw has to do with the surface tension of the water not allowing air through, therefore increase the area and the waters surface tension will give way to the weight of the water

>>4478527
only one that made me laugh. congrats.

>He doesn't know that water is polarised anyway and is affected by magnets..

>>4478752

>>4479153
I like this one a lot.

>>4478693
This is not even troll science

If you could make a material light and strong enough, this will actually work

One thing I never understood. With capillary effect, the water rises, thus having a higher center of mass, therefore having a greater potential energy. Where does this extra energy come from?

>>4479214
>If you could make a material light and strong enough, this will actually work
therein lies the troll

>>4478682
this would also work if we could prevent energy degradation

>>4478527
my sides

>Is it possible for neutrino's to travel faster than the speed of light? OR would that also violate the grand theory? My head says no, but my heart says yes

>Nothing can move faster than the speed of light, consequently, space is nothing and thus can expand faster than the speed of light

>Einstein's Theory is exactly that. A theory. Nothing is impossible when it comes to Astrophysics.

:I think that speed is relative and therefore you cannot estimate the speed in which the universe expands. It is comparable to light which is calculated to extremely accurate measurements. The lack of evidence pointing to any plausible answer in actuality is absolutely impossible, therefore neither is provable in any definitive answer

>I think dark energy and dark matter are semi-visible manifestations of time itself.

>It would require an infinite power source to move faster than the speed of light. If the Big Bang was, in fact, a collision of two membranes (as M theory states) or an explosion, as the older physics model states, the energy produced would be immense, but not infinite... So, no, it's not possible unless Einstein was wrong

>It's much like if you were to grab two laser beams, one in each hand, and outstretch your arms in complete opposite directions. The two laser beams are travelling away from one another at twice the speed of light.

>forget light speed. gravity speed is where its at.

>Expansion is NOT light, therefore it doesn't violate any law on Light speed as light doesn't enter into the equation.. it would be like saying does a potato effect the speed of the space shuttle......

>Ah anything is NOT possible. It is physiclly impossible for life and free will to exist independant of suffering. If one lives and has free will one can and eventually will make a mistake which will lead to suffering.

>Aaron already gave you the answer, yes , space can expand faster than the speed of light, but no faster than the speed of gravity.

>The universe is expanding into nothing and has all the energy of the universe to expand, a photon is traveling in space with less energy then the universe but the most energy and less mass of any signal particle in the universe so therefore it can travel faster then the universe. The average expansion of the universe is 3.381725016 times the speed of light. Speed of light is 186,282 miles per second and the average expansion of the universe is 629,954.4994 miles per second.

>Hasn't quantum physics proven that particles exist at more than one place simultaneously?

>Idk about all that lol. I've come to believe that evolution starts with Solar and other radiation that flows onto our planet, morphing our brains and DNA, which would cause our body to have to adapt and change both physically, mentally and spiritually. To me that would seem the most plausible explanation for everything on the planet undergoing the same process that is evolution.

>Evolution is just learning from mistakes that we've made over thousands of years

>>4479193

I agree. This is my favorite.

>>4478700
Magnetic field weakens as distance increase. The water(or ferrofluid) can't continue flowing.
>>4479045
Unless the rate in which the oxygen and CO2 released by the plant and you respectively, is similar, wouldn't work. Pretty sure it's not. Plus, plants may also take in oxygen and releases CO2.
>>4479163
No. Both magnets attract each other, thus, making zero net forces.

>>4479686
Unless the chair has a really huge mass, thus increasing the inertia, this wouldn't work.

>>4479732

so, this can actually work if the chair has big mass???

>>4480017

Of course not. Think of plane crash

>>4480017

you cannot cancel all the g you accumulate while falling down.

>>4480419
The strength differences are negligible.

>>4480017
No say you and the chair are falling at 300m/s and you jump up at 5m/s you will still be moving 295m/s.

>>4480555
Especially when compared to the transportation costs
