To what extent does neuroplasticity work? My brain is pretty fucking damaged from laziness and unhealthy lifestyle. IQ must be at about 90 I reckon. I'm 27. Can still get smart if I work hard from now on? Thinking about deleting system32 if there's no hope.

Also, working hard is only gonna make things better. No point in not trying.

Brain literally works by just creating neuronal paths. Practice makes perfect is true because by repeatedly doing certain actions your brain will develop to automate that perfection and make these neuronal paths stronger.

AP without a question.

American universities are, after all, the best in the world, and AP courses are modeled after the courses offered at these institutions.

I feel extreme guilty as I begin orgasm. I feel so guilty that I pick up my telephone and call Mother in Russia. I awaken her. It too late for stopping so I am cumming sex. I am very upset and guilty and crying, so I yell her, "I AM CUM FROM SEX" (in Russia). She say what?

Hello, I'm currently taking statistics and someone in my class mentioned to me that there is a way to program your calculator to help you immensely for exams. Does anyone know what he is talking about? How do I do this?

Is there a reason why this can't work?

It's a patent for inducing physiological states in the nervous system through weak electromagnetic fields via a computer screen.

>>7813541
well for one, no one uses CRTs anymore. Second at those distances the magnetic field would be really fucking weak and liable to being drown out by other environmental magnetic fields.

That's not to say you can't mess with the brain using magnetic fields though. But current transcranial magnetic stimulation setups need precise positioning and relatively high magnetic fields to have any effect.

>>7813541
The magnetic field would probably need to be so powerful your electricity bill would be 2k a month and it'd probably just give you a headache or make you nauseated like most other kinds of brainwave-matching EM waves.

Might work, but not really workable if the idea is to brain-wash people into buying a new brainwashing television set every 3 months.

Why is it food cost nearly twice as much now as it did a decade ago but we're producing twice as much food? This isn't how supply and demand works. GMO promised us cheaper food but is it making food more expensive?

GMO means patent, which means monopolistic intellectual property exploitation, which means distortion of market prices.

Wait for the inevitable 21st century oil shock in the other direction, as in over $200 a barrel or something. We eat oil today, bad planning. All it takes is a few Allah Ackbars over there in the ME, a Russian bear gone berserk, a rogue China...the possibilities are endless.

How is it that a photon which is emitted from an object with a recession velocity greater than c can reach us at all? I understand that at first the photon is indeed receding but how can it ever reach a coordinate point where the recession velocity is less than c if it started out in one that was greater than c? Shouldn't the nature of accelerated expansion imply that it will only ever recede because distance is being "created" faster than light can traverse that distance?

the answer is: dark matter.

>>7812389

The photon cannot travel faster than the spacetime expansion, this is the postulated fate of the future universe where the sky beyond locality is completely dark.

Every time it was brought up I'm told it's suddenly useless and unemployable.

Let's see if you anons are smart. It is actually a nice puzzle:

A flight is taking off soon, and there are 100 assigned seats, and the passengers enter in order of their seat #.

Passenger X loses their ticket and sits in a random seat.

What's the probability that the 100th person will be seated at their assigned seat?

Note: a passenger will always sit in their assigned seat unless it is taken. If their seat is taken, they will sit in a random seat.

100% if there is only 100 seats in the plane. The last guy will only have one seat left to sit in.
>>
>>7813752
Passenger X sits in a random seat. There's a chance that the 100th person won't have their seat.

Another issue is passenger X takes passenger's 60th seat, and passenger 60 sits on the 100th spot.

Listen you brainlet, if you travel upward at a speed of 1mph for a billion years you're going to escape earth's gravity. Now extend that analogy to spacecraft, and think about what escape velocity actually means versus what happens with spacecraft.

So......why exactly are we still using chemical rockets to go to space despite the fact the military has already experimented and FLIGHT PROVEN with fucking ELECTROSTATIC ION ENGINES and HALL EFFECT THRUSTERS decades ago?

No, it is because there is yet no even a theoretical basis for 'general AI'.

And as we know is true for all things in math, between the theory and the actual application, there are 300 years inbetween.

You develop the theory for general and AI and I'll see you in 2316.
