Alot of these points seem to contradict gravity, now this will make a lot of freshmen engineers butthurt but the simple, layman evidence keeps piling up these days, especially since the invention of Youtube where people can actually post their experiments that go against mainstream ideas. Has anyone actually read the paper on Gravity? Can you explain what gravity is or how it works without looking up some esoteric paper written hundreds of years ago, using proof that the average person can understand?

So gravity is the apparent force exerted on us due to the expansion of the universe? Like getting pushed back in your car seat when accelerating?

That's why gravity would be less towards the centre of the planet, right? Less mass moving "outwards" with the expansion of the universe to feel the effects of inertia.

gravity is an unneccesary and unproven explanation anyway

"The first gulp from the glass of natural sciences will make you an atheist, but at the bottom of the glass God is waiting for you." - Werner Heisenberg

It means that most people who are smart enough to complete rigorous education in natural sciences are also smart enough to grow out of edgy fedoralord materialism and understand that science and religion are two completely different domains.

Discovering that life's incredible natural processes are self-regulating understandably makes one critical of sentiments like "God raises the sun every morning," and other religious notions that man and nature requires active oversight when change over time largely follows understood priori and trends.

However, deeper down the rabbit hole of human discovery still lies deep unknowns, irrational and unnatural phenomena that are accounted for but have never been understood. Modern schools of thought and formula theorize that there is in fact a limit to human comprehension of the universe as well. When you spend so much time analyzing the unnecessarily beautiful world we live in, it no longer seems foreign to believe in an active deity, sustaining and creating in the present day.

How far can you get with populating with just one man and one woman?

I heard you maybe able to breed up to a village before there starts to be problems with the genetic code. Is this true?

Also, why is incest a problem if in both the Genesis scenario and the actual scenario both involve a little incest?

There would be all sorts of problems initially, but eventually enough mutation will occur that the gene pool will start to correct itself. That will take a very long amount of time, but can be hastened with proper monitoring and selective breeding.

So hypothetically, if a man were to construct a rocket ship with warp drive to take himself, his wife, and a robot with him to another planet then there is still a chance of populating that new planet? What if there were aliens there who are compatible with humans?

There are 9 coins, one of them is fake and weighs less. You can use the scale only 2 times. How do you determine which one is the fake?
17 posts and 1 images submitted.
>>
First pick 3 and compare them to any other 3. Then you have it narrowed down to 3.

Then pick any one of the three and compare it to any other one
>>
Put 4 one, 5 in the other.
Then do the same for the ones in the scale which weighed the least.
You could probably find it then.

How bullshit is the whole "limited willpower" thing that psychologists tell us about?

I'm asking in the context of sticking to a schedule. Every time I come up with a schedule, it drops off after maybe a few weeks maximum. I want to know if there is a scientific explanation for this that is beyond my control or if I'm just a lazy asshole.

Rip, You're just lazy.
I read in our schools psychology textbook that the theory of limited willpower was only proven in one experiment and since then has never been replicated. Willpower has been shown to dramatically change by doing arbitrary things like eating a tasty cookie. You pretty much have infinite willpower dude.

Guys, how I git gud at integral calculus. Time is running out until the end of the semester and my calculus finals, and this shit is killing me. I've spent 5 hours today just pondering over a single equation and I still can't figure it out. I've got other things to do but I can't move on until I understand these integration problems.

For those wondering, the equation in question is (1 / (g - k*v^2)) dv
Even a relatively simple expression like this has me absolutely stumped. What do?

>>8925223
Trigonometric substitution
>>
ok this one is easy

first factor out g, so you have 1/(g*(1-k/g*v^2))
now you substitute u=sqrt(k/g)*v, so du/sqrt(k/g)=dv
now you have some prefactor, lets call it A*1/(1-u^2)du. Now you rip it apart and say OK: 1/(1-u^2)=C1/(1+u)+C2/(1-u). Determine C1 and C2 such that the equality holds and now you only have to integrate 1+-u which is ln(1+-u). mix everything together, simplify and you should end up with something like prefactor*arctan(something)
you're welcome
>>
>>8925223
The only way is to sit down and integrate like a madman, after you have integrated hundreds of exercises you will be set. There are no standard paths to integrate so you must get the intuition by grinding.

I want to get to a point where I can understand as much as possible about as many fields as possible, to a point where I can pick up a random scientific journal and have an 85-99% of knowing what's going on.

I'm focusin on physics, chemistry, math, quantum mechanics, and astronomy.

Once I level up my math skills enough to finish Feynman, where should I go from there? I've got nothing but time and downloaded textbooks on subjects I've never even heard of; I just need to know what the most productive route is for learning as close to a theory of everything as an individual human can at this point in history.

What do next?

Ecology, systems&network theory/science
People who don't know life sciences and can't look at nature as an interactive whole are pretty boring imo
>>
>>8925091
Cool, that's an idea.

I'm looking at going from Feynman into "Fundamentals of Molecular Engineering" and a bunch of books on electromagnetics and microwave and antenna design.

But also move forward in some other areas.

Seems to me that physics is more theoreticsl and requires more abstract thinking, whereas chemistry mostly consists of plugging observation-based numbers into a equation for the purpose of findinging the likely result of putting two substances together,
