Rocks exist because gravity.
Without gravity, stars would have never formed, and thus heavier elements would have never been created to later be collected by gravity to form rocks.

Do you think one day we might be able to enhance our brains with cybernetics, to the point where we might be able to learn what takes years to learn, in a matter of minutes or hours?

Could be possible for non "enhanced" beings also involving optic intelligent light pulse information transference, densely (or lightly) packed edutainment VR simulations, and genetic information (experiential and instinctual) storage.

what's up /sci/ niggers!
can the knapsack problem be applied to solving diophantine equations?
https://en.wikipedia.org/wiki/Knapsack_problem
if you have a linear equation like:
Ax + By + Cz = D where A,B,C,D are integers, can it be mapped (or whatever the right term is) to the knapsack problem?

don't know. can linear programming find the exact integer solution to a linear equation with three unknowns? the examples in your link deal with equations with two unknowns, that also have additional constraints (inequalities)

with a sufficiently fast baseball bat it should be possible.
>>What would be the physics involved?
if you give something enough kinetic energy, it will do grievous damage to whatever it hits.
Heck they even make baseball bats out of aluminum, you could probably get one of those suckers moving up to kilometers per second without it burning up in the atmosphere before traveling a reasonable distance.

What's a good way to review basic high school math topics? I just want to clear up any embarrassing gaps I might have in my knowledge.
Specifically, where could I find good practice problems to test my knowledge?

How do we harness the placebo effect?
Is it possible for placebo effect can work even if you're aware it's placebo if you make yourself more susceptible first? As in, "Take these placebo susceptibility pills. It's just a placebo, but they'll make you 100 times more likely to experience the placebo effect. Now take this other placebo that's suppose to do help you with your illness."
Also, what happens when someone is given an anti-placebo placebo? Would that even work?

are we talking knee replacement surgery? Or just tendon reshaping? Methinks both persons knees started rebuilding themselves after incision, because their bodies knew the knee was split open. All they really do is scrape the tendons so they regrow stronger tissue.

Do you mean a Nocebo by anti-placebo placebo? Yes, there are nocebos, and they can be lethal. Amazing right?
You can make yourself susceptible. The technique takes time but its essence is similar to how a child's brain Has to operate. A child is born and learn a few words, a few concepts, not nearly enough to put the accurate expression of her thoughts into sentences, nor to model the world. So the boy relies on categories associated to those few words and concepts, and any element has to fit these, triggering the category just like in basic pattern recognition. Think of it in numerical language: you have 3 sets and 10 elements, seeing any element signals your brain, your brain amplifies the signal to match the category. Two interesting categories than are: Truth and Falsehood, which should be able to map the entire child's reality. If these are broken, then sure you are not going to be able to assign beliefs, you will have to live without voluntary placebos.

Look at these two factorizations for the product (x - 1)(x - 2):
(x - 1)(x - 2) = x(x - 2) - 1(x - 2) = x^2 - 2x - x - 2 = x^2 - 3x - 2.
(x - 1)(x - 2) = x(x - 2) - 1(x - 2) = x * x + x(-2) + (-1)x + (-1)(-2) = x^2 + (-3)x + 2.
Now I need somebody to explain this shit to me. Why is the second one correct when the only thing done differently is representing subtraction in terms of addition? And is it even possible to get the correct answer without doing this?

Dear people.
I am looking for a chemical presertive that will lower your blood pressure. It is a powser and at 2 grams you will go in 20 minutes in come and in an hour you will die. It is also soluble in water so please help me find this presertive. I was thinking about TBHQ but that wasnt really soluble in water. You can also buy this freely so maybe that will give you another clue. Its working like carbon monoxide. All of course in the name of science

Well I was missing that it main use is to keep food longer preservable. Cyanide is hard to get.

is it worth going to a graduate school in machine learning or related degree for this?
is the industry experience enough with studying alone or formal education is necessary to reach a level where I can compete with ML start up companies?

By the time you finished, venture capitalists will have realized that Machine Learning is a scam and stop funding their go-nowhere startup addiction.

Anything you can do in Machine Learning without a PhD, an H1B from india or china can cook up in Tensorflow over a weekend.
AI is an incredible research field to be in right now. But as far as start ups go, its a complete bubble and your only plan should be to pump and dump your company

By definition A.I. is uncontrollable. Even if we have the advantage of being its creators, just one slip would be enough to lose control.
And I'm saying that there would be evil robots shooting lasers everywhere. Not at all. Humans, being vastly inferior, would just become obsolete and powerless. We could just become extinct as a side effect of something A.I. does without any intention of killing us.

Hmm, honestly OP I'd have to agree with you but I think it will happen 99 percent of humanity, while the elite of our kind will become the superior AI.

A hyper-intelligent A.I. could predict any and all movements that humans could make both as individuals and as a whole. There's absolutely no defeating it.

I didn't expect this sort of paranoia on /sci/. I honestly just found his youtube channel, and all I know about him is that he makes long videos about science/science fiction concepts.
Is there something you don't like about him? I know basically nothing about the guy, so just tell me.
