/sci/ is american so probably won't feel any way. I am not but I also have no feelings towards it. Now I'm out of it let the other kids burn I say.

Too fucking slow and doesn't cover nearly enough material.

People not interested in learning need to get the fuck out.

Sine about 1950 problems have compounded each other to the point where the public K12 system is almost unsalavgable.


First, integration needed to occur (inb4 /pol/ shows up). The shock of it has never been resolved. Then schools stopped getting enough money to operate. Then teachers unions went full strike mode because they don't want their pay cut or any sort of accountability introduced on their end. What we have now is a huge fucking mess. Affirmative Action court orders from the 60s go up against modern PTAs setup by the NCLB. Schools are responsible to individual cities, counties, school districts, states, and DC with no clear chain of command.

The the Common Core comes in and standardizes everything into one system. This fixed a lot of the problems with the system, namely a lack of any single standardized metric to judge teacher quality. Problem is, a) the CC is more than just tests, it's curricula too and b) because CC tests determine how much federal money schools qualify for, schools have no incentive to teach anything other than what's exactly on the test. Schools also don't get as much money if their students choose an apprenticeship or military enlistment compared to college enrollment.

This also leads to another problem, overfilled colleges. Which leads to colleges dumping quality cirricula and standards as they have no incentive to compete now as there's an oversupply of paying, stupid students. The result of this is that you get colleges doing stupid things, like banning free speech, that goes against their supposed reason for existing. Now the public university system has the same issues the public K12 system does.

It's not disprovable in any case, just a modern version of Descartes' demon they're using to sell books to you.

Anyway, I would like to point out that the "simulation argument" doesn't really stack with evidence that physical properties are quantized, etc. in terms of credibility. Not in the way you might think it does at least. I mean, are they saying these artifacts of the simulation are present in the real-real world or not? If they are, then all it indicates is that reality is simulable. If they're not there then our world has already deviated in major ways from one of these ancestor simulations (the existence of the simulation hypothesis itself being a prime example.)

Another thing to ask yourself: Would the knowledge that you are living in a simulation, with no way to know the kind of simulation it was, carry any moral weight? Would you do anything differently? And if so, why?

>>7668282
>Would the knowledge that you are living in a simulation, with no way to know the kind of simulation it was, carry any moral weight? Would you do anything differently?

No, I would not, because the "simulation" would still be all the "reality" we will ever know. It is practically indisguishable from reality.

Subject is still interesting tho

>>7668282
I would look for a way to threaten the stability of the simulation so that I could get in contact with the runners of the simulation and try and force them to give me a robot body in their world.

Nah, just kidding, I'd tug at the stability of the universe if the opportunity arose even if I didn't think I was in a simulation.

I'm not sure to be honest. I happen to think anything involving science or math is worth the praise. Computer science too, but /sci/ doesn't like CS majors either. Maybe it's because people here just like to argue and show off how much they know in one field.

>>7668192

Because it's easier to pretend to be a theoretical scientist or a mathematician than it is an engineer.

Engineers usually actually produce something. It would be quite a feat to convince yourself that you are an engineer if you haven't done jack shit in your life. On the other hand, the work of a mathematician or theoretical scientist is usually more ephemeral, their work might not bear physical fruit in their lifetime and sometimes it is entirely theoretical. Much easier to delude yourself into believing you are this type of person.

>>7668192

We don't. There's one really autistic physics drop out that thinks engineering is blasphemy to the church of physics that used to spam gay porn and one tryhard kid that parrots him to fit in here.

No. Mathematical infinity does not invite absurdity. There are infinitely many odd numbers, none of them are even.

The Boltzmann brain theory is retarded. Life is cosmic orders of magnitude beyond cosmically unlikely. It takes more than "random fluctuation and high chaos" to form a sophistication of structure that is able to be functionally aware of itself. No matter how many fantastic-sounding nonsenses you throw around, abiogenesis and evolution are laborious and gradual processes. They don't just randomly happen all at once because you don't understand Quantum Mechanics very well.

So what do you suppose the nature of meta or semi physical such as phase space or spin would be involved in non-existence OP?

Just curious how such would fit in to your synopsis of the semantics of nothing

>>7667887
Knowing you're in way over your head but you have to keep going to the class to keep up pretenses and it feels like you're drowning but you don't know what you can do about it.

>making elementary math errors

No I do not know this feel

Knowing that you will live for only five years is a pretty negative feeling.

Wiki link says that death caused by the syndrome is very sudden.

Congrats! You have a method of dying that will be quick, less painful than many and not considered as suicide. If you can find a way to make yourself happy with dying and also happy with living, you'll have all of the man existential problems in a life like ours completely sorted out.

Learning to be happy with both life and death is, of course, the rub. Since you are good with the latter, I suggest reading various philosophies to see if you can find a way you like of living.

"What should I acquire"? I suggest the enchiridion ( http://classics.mit.edu/Epictetus/epicench.html ) as a short starting point. Find more on living/ life and death as when you've finished it (eg Camus "One must imagine Sisyphus happy").

Good luck OP

>>7667871
Oh.. I have that book by Camus... I never finished it.. I'm going to, while waiting for other answers but thanks for your time and advices.

Bumping. I wish you well OP.

looks like a piece of shit granted,
but still remains the only vehicle ever designed and built to land on another world.

>>7667830
Absolutely not true, the many varied Mars rovers come to mind (specifically their landing platforms). Next time specify manned landers.

Don't be problematic. You know what he meant.
Who gives a fuck about rovers.

something about the distance between the electron levels

so conjugated systems (shit with double bonds) usually have lower energy levels, that allows for electron transfers of the appropriate energies to correspond to visible light

Speaking with 1 semester of Chemistry background

>>7667540
You're basically right. Essentially for light to be emitted an electron needs to go from an excited state to a lower energy state. The released energy will be in the form of a photon. A heavily conjugated pi-bond system will have smaller energy difference between the highest occupied and lowest unoccupied orbital (energy level, essentially). Some of them are low enough to be in the visible range.

As for shiny vs matte that's a tad bit more complicated, despite involving less QM. I'm not 100% sure but I think, for a given material, the biggest factor is actually the angle of incidence that the light hits the surface. As well as how smooth the finish on the surface is.

>>7667552
So something like biphenyl won't have much of a color because it has many pi bonds, but a diatomic molecule pair of hydrogen or chlorine will?
