why are math, physics and philosophy the only worthy pursuits of mankind?
>>8109090
They aren't, if you truly think that you are delusional and using pseudoscience.
maths can be done without physics
physics can't be done without maths
philosophy is pure garbage
what is the difference between inertia and conservation of momentum ?
which one imply the other or are they equivalent ?
They come together, the first is used quantitatively. An object has more or less inerta (just like it has more or less mass or momentum), while the conservation of momentum is just a given feature of momentum.
Question: How strong would an ant's exoskeleton be if scaled up to the size of a large dog?
Image not related.
It doesn't work like that
>>8108472
Explain.
>>8108465
Only the exoeskeleton, nothing. It needs muscle fibres.
An ant the size of a dog in current atmosphere would not be able to breath, so again, nothing.
There are giant spider crabs in the sea and they can't lift shit, if that tells you something.

the failure of positivism
I saw something in the sky tonight and I don't know what it was. It was around 2:20 AM in the morning, I was going for a walk and I was walking up a hill looking over the beach as I was walking I saw this giant light in the sky. It looked like an icecreamcone or lightbulb of fire in the sky. I kept watching it to figure out what the fuck it was. I thought it was a nuclear bomb for a second but then I realized it wasn't a mushroom cloud shape.
I kept watching it and eventually it formed into what looked like a big giant red moon being covered by clouds, then...

Oh and by sky I mean in the horizon. It wasn't wide it was tall and fat on the bottom. Candestick flame would be perfect example.
like this?

I didn't see the beginning of what started it, I just stumbled about it while I was walking. It lasted much longer than that video and it wasn't a mushroom explosion

I feel you bro
advice: divide the parameters' intervals in 5 for each parameter, run the algorithm say 10 times for each combination of parameters, and evaluate some performance (speed of convergence, error or whatever).
do this automatically by using your already existing script in a quadruple loop, and don't forget to store the results.
This should give you a rough idea of what to do.
Let it run and go do something else.

These niggas literally just gave it a name and kept using it while I was trying to reproduce their results.
How can absolute morons become so rich, while really smart people like scientists remain poor?
This is not just a modern phenomenon, it has persisted throughout human history. Does that mean being smart has less evolutionary importance than being a cunt?
>>8107770
because they are smarter than scientists
I consider myself smart and I don't care much for money.

the people with the best paying jobs wont be the most intelligent people, or the most qualified for their jobs, they will be the people who are best at getting well paid jobs

Memorisation
Hi /sci/, what techniques/methods do you use to improve commitment of information to long-term memory?
Too often I find myself forgetting things that I learnt a few years ago and it makes me unsettled and makes me view the time I spent studying the subjects to have been wasted if I can't even recall it a few years later.
1.) Put them in a context that makes what you're studying important
2.) Rhythmic memorization
Also these:

fap while memorizing
>>8107551
I'm synesthetic (Grapheme-color so numbers/letters are colors), so that helps. This is going to sound super autistic, but whenever I need to memorize a lot of information, recall an image of an intersection near my house and group individual elements as parts of the picture (so in this example, frontal lobe could correspond with the house that is on this intersection and the individual parts would be parts of the house grouped by the colors I associate with them). It's harder for long words because they don't...

Does gravity exist outside of our universe?
What is gravity?
The universe contains all possible sets and members. Therefore, no.
Gravity propagates at the speed of light.
So no.
Do non-local correlations imply the existence of a preferred reference frame?
>>8107258
No. The only known non-local connection is the collapse of quantum entanglement, which is so limited in its effects and properties that in some interpretations of quantum mechanics there's no faster-than-light effect at all.
>>8107263
but if the correlations demonstrated by entanglement are indeed caused by some action at a distance, would that mean there is a preferred reference frame?
No. Because the populations are chosen and biased by their intent and their objectification.
I figured this was the most academic board on here.
I need some input, I have a low gpa of 2.4 and the jobs or graduate schools that i want to go to have a cutoff of 3. I could graduate with a 2.8 realistically but my advisor gave me some strange advice.
She told me that if I transferred to another school and graduated in two years from it I would come out with a higher gpa and be more qualified to work where i want to work or get into a better school for graduate school.
The part that confuses me is that she implied that transferring to another school...

posted there too, thanks for responding.
I'm doing a lot of research now but I'm not certain yet. I cant talk to my advisor again until wednesday because shes busy but I wanted to see if this was a common option.
I did some research and the GPA does reset in that your degree will have only the GPA at the new uni attached to it, but I'm now unsure about the transfer process.
Has anyone else transferred from school to school for any reason?
Where does Autism come from? Could it be vaccines, plastics, automobile exhaust, electromagnetic radiation, pills during pregnancy, lack of maternal warmth, or etc.?
>>8107083
Autism doesn't exist. The meme comes from schools wanting something to blame for kids not being well adjusted.
and genetics of course

This. Couple of days back at work I was asked by a co-worker how I learned programming. He specifically asked 'What books' and I was like what the hell. I learned from a website.
That said, some goods are just too good my man.
CL FUCKING RS. Introduction to Algorithms motherfucker. Before reading this I was a block of rock and after it I was chiseled into Michelangelo's David when it came to my knowledge of computation.

Fuck that. Every time I look at the online resources for things that I have a non-surface-level understanding of it makes me want to blow my brains out
I know that legally a person can do an undefined numbers of degrees. But how much can a human mind handle?
>Unreleated pic

>>8106671
There is no limit. You could just keep doing them one right after the other and you would never come at a point where you could not keep going.
And if you mean at the same time, probably 3 but you have to be autistic and have no social life.
Other than that, it should be illegal to even do double majors and it should also be illegal to go back to university for a second degree (of the level) before at the very least 5 years in industry, specially if your education was funded by financial aid programs.

if you can handle a degree you can handle all degrees of that 'level' .why would you fucking choose to do so is another thing entirely .
just go for a degree in whatever you find most interesting and read books of whatever other subject you find interesting .
that way you can fuck around and study the other shit at your own pace and maybe go to a course or two if they have a really good professor or something .
studied chemistry that way with a totally bro chem professor while doing a physics degree .
