ultimately it goes back to the big bang, and how it came to be. hard to answer the question

>>7964695
The question makes no sense. If "you" were an AI or a non-human, you wouldn't be "you". It's not like your soul is floating around and it goes into a random fetus. "You" are just the result of many many many many many many reactions. Flip a coin ten times. How is it that the specific pattern you got occurred when there are 2^10 possible patterns? It just happened that way and it's not very mysterious or shocking is it?

transforming kinetic energy from wind into electric energy for other uses does change how the wind moves. have you done the math to know using it for 100% of our electricity wouldn't have an effect?

>>7964614

any change in wind patterns (not in atmosphere) seems trivial to celestial mechanics

also the guy linked a satire (think 'the onion' but for science) institute as his source

any physicists wanna pitch in?

>>7964614
Yeah Brazilians aren't particularly bright, what bothers me more is how smug that retard is.

People who don't know they are retarded are dangerous.

General wing surface area looks like it'd be fine, looks like it'd flip shit if you put any kind of roll on it though. Yaw seems like it would be finnicky as fuck in the early MET, but I'm guessing it'd stabilize-ish after awhile.
That's a big ass intake though, and I can't tell if it's mirrored or not.
Seems like a huge waste of drag surface if it's just a big-ass ram scoop. It's a bit odd for a normal intake, though.

>>7964549
no it can not fly
i recommend the people in that car to jump off now

Someone post the mind of the samurai copypasta.

Also, if you had a cylinder filled with a gas like hydrogen, and you had a piston at one end with an explosive on the other side, and the velocity of the explosive's detonation was higher than the gas's speed of sound, what would happen?

>What is the difference between a railgun and a coilgun?

Wikipedia it. One uses rails, the other one or many coils.

>and the velocity of the explosive's detonation was higher than the gas's speed of sound, what would happen?
Piston travels down tube and compresses gas, you just described a Light-Gas gun which you can also wikipedia for details.

Why ask retard central something when you can wikipedia it instead?

Decent place to get a general overview. If you want deeper understanding, follow the source links.

What exactly ido you mean by "wrong", fgt?

>>7962735
Wikipedia being wrong is just misconception of retarded teens.

kinda seems like a cover for a gay sex ring

because i already joined ASME

Kek, they just started that this year at my school. It's a bunch of awkward engineer phaggots. Do NOT join an academic frat.

wolframalpha

It's called non-linear regression analysis. I made a program like this in Python recently and will release it as free software soon.

Predictive power, reproducibility, ability to distinguish signal from interest variable from confounding variable noise

Psychology comes up shorter on all of these than hard sciences do

>>7957458
I'd say it has quite the predictive power and reproducibility. It's just "unethical" to conduct these experiments.

That last one is a difficulty most sciences had or continue to have but is made easier with the advancing of research environment


Let me ask you one thing, though. Are the findings of psychological research false? Do they not have practical uses in the world?

>>7957498
>I'd say it has quite the predictive power and reproducibility.
You would be wrong.

Geniuses are criminals for suggesting they are like everyone. People might actually believe that and waste their lives pursuing careers they have no chance on,

>>7964029
Feynman was actually a nice guy by being a prick to his students, rubbing in their faces how their research was trivial and irrelevant.

Pure physics/maths is only for the greatest.

Could those smiles be any more forced ?

She looks way hotter in the last 4 pics excluding the poor second to last one.

Have fun

My hardest year is still to come, it's going to be the second semester of my masters (so in 2017), I'll be taking:
>Modern QFT
>General Relativity
>Hamiltonian Dynamics
>Differentiable manifolds
>Algebraic topology
>Algebraic geometry

It's going to be hard because I didn't meet the prerequisites for any of them (except Hamiltonian Dynamics), and I've taken some hard math electives (which I think I'm going to regret since I did my undergrad in physics and have very little exposure to proofs other than what I've taught myself). Still, should be fun.

At least I'm not alone.

The French are still best at math

set theory is used by physicists. When they say that ''the mass is 10 kg'' they literally believe that there is a number 10 floating in space and somehow giving you the answer on your measuring device..

Now, what framework for numbers ? it is set theory, where numbers are encoded as sets.

Since physicists believe that the mathematical inferences describe the world, when the inferences lead to quantified/numeric facts, they equally believe that the axioms of the set theory is true.
The first axiom of set theory is ''there exists a set''. so physicists believe that there is some set floating around.

What are you still doing here? I thought I told you to go fuck your mother.

I hate that book so much.

At least you didn't have to use Bretscher :,(

I learned more from Reif which is almost 60 years old at this point.
