So, does gravity abide by the speed of light?

I mean, hypothetically, if the sun were to blink out of existence would we fell the gravitational effect immediately or 8 minutes after?

what are ideas? neural connections in the brain

so, if someone can map all neural connection of a specific idea, maybe he can also construct that neural connection in other brain. It will be a complete idea transfer between two brain.

You won't use words to explain something to somebody anymore. You will only tranfer your idea to the persons brain you're talking to.

It has a quite wide use. Not more reading books or learning something by classical method. You only will download all neural connections necessary.

You guys believe will it be possible someday? How long to it get real?

Transplanting a neuron cluster from one brain to another would be like cutting out a random bit of machine language code from one program and putting it in another. There's the slightest chance that it'll do what you want but most of the time it would just as good as random bytes.

Would this not be working backwards in terms of transgenders gaining acceptance? If I am not mistaken, their "evidence" that transgenders aren't kooks is that their brains look like the opposite sex in scans.

>tl;dr brains aren't gendered so how are transgendered individuals not wackjobs?

>Although von Neumann unfailingly dressed formally, he enjoyed throwing extravagant parties and driving hazardously (frequently while reading a book, and sometimes crashing into a tree or getting arrested).[2] He once reported one of his many car accidents in this way: "I was proceeding down the road. The trees on the right were passing me in orderly fashion at 60 miles per hour. Suddenly one of them stepped in my path."[3] He was a profoundly committed hedonist who liked to eat and drink heavily (it was said that he knew how to count everything except calories), [4] and persistently gaze at the legs of young women (so much so that female secretaries at Los Alamos often covered up the exposed undersides of their desks with cardboard).[5]

The "gravitational constant" is a myth, and if your physics courses still teach it as immutable truth then you need to switch schools.

There's "simplification" and then there's just flat out wrong.

An equivalent would be like if in biology, you learned Biblical creationism and Lamarckian evolution for the first couple semesters before "graduating" to actual biology.

I've discovered the numberphile channel so far, and I'm really amazed by it. It's well explained without much silly talk, but not too complicated for (at least) college students. Does somebody also know other youtube channels for different scientific areas (as for example physics?).
Would be really great, if somebody posts them

I feel like I will be shunned for asking this dumb question but,

If you throw a ball 10mph up in the air 50ft, how fast will it go when it comes back down...and how do u solve this please so I can study more of this stuff

It should come down at the exact same speed. Considering we are taking out the affect of air and wind.

Remember that throughout its flight, as long as you negate air friction, potential energy + kinetic energy are always the same.

Example:
PE1 + KE1 = PE2 + KE2

The nist wtc experiments imply the steel weakened 50%

Jews did wtc

Can't argue with that... math?

1 divided by 20 is 0.05, which is a 50% drop (0.05% drop is the inverse of 50.0% gain).

The match checks out.

It wasn't just the steel weakening, the whole structure was fucked at initial impact. You know, by having a plane pass through it...

π: ratio of circle's circumference to it's diameter

we can generalize this concept to n dimensions

1_π: what we generally call pi, or the ratio of a 1-sphere's circumference to the line bisecting it: 2πr/2r = π
2_π: ratio of 2-sphere's surface area to the area enclosed by the 1-sphere bisecting it 4πr^2/πr^2 = 4
3_π: ratio of 3-sphere's surface volume to the volume enclosed by the 2-sphere bisecting it 2π^2r^3/(4pir^3/3) = 3π/2

in general, n_π is the ratio of an n-sphere's (n-1) bounding surface space to the space enclosed by the n-2 sphere bisecting it: given by the equation:

n_π = 2√π * Γ((n+1)/2)/Γ(n/2)

From this we can see that in even dimensions n_π is a rational number but in odd dimensions n_π is transcendental.

consciousness can only exist when π is transcendental, our space is conveniently 3 dimensions

you exist due to pure anthropic chance

ETH Zürich physics student reporting in, bretty good, workload is intense, but the second and third year of the bachelor are rumored to be less stressfull. The ETH is among the best universities of the world when it comes to physics. (still wishing I was studying in Cambridge though, oh well).
Any questions?

>Girls do better than boys in math + science
That is definitely not true. I will give them that girls and boys can be as good as each other when it comes to math and science. Seriously, this femenist proapaganda of "womyn be gud and buys b dumm" hurts my head.

>stereotypes keep them away from STEM
Says who? Where's the data. Has a woman ever said:
Oh, I really wanted to get a 300k starting job in mathematics but the stereotypes just pushed me away to psychology to get this shitty 30k job.

Because that's bullshit. Nobody would shy away from making bank because stereotypes that don't even exist anyways. Women get in STEM and do just fine. None of them get raped by the creepy engineers like feminists claim.
>>
>>7698667
Arguable, the success you experience in school and the success you gain in professional work is not likely as correlated as you would like. The 1%'ers that make it as successful and productive STEM'ers, especially in the hard sciences, are different in a way grades only partially show. They certainly got good grades, but there is a huge difference between learning and creating.
