> The star Kepler 11145123 is the roundest natural object ever measured in the universe.
> Stellar oscillations imply a difference in radius between the equator and the poles of only 3 km. This star is significantly more round than the sun.
What is the scientific explaination between this impossibly perfect roundness of a star 2 times bigger than the sun? It's a gas sphere so it is a lot more vulnerable to the random debris, piercing asteroids and other distorting forces around the space but it doesn't seem to be effected by them.
What are the implications of this unnatural precision?

didnt we find that an electron in terms of charge distribution is an exact sphere?
>>
>>8480247
the dust cloud in which the star was formed had a near net 0 angular momentum.
>>
>>8480247
It's very possible the planet has nothing orbiting it, and a lack of any noticeable gravity well may explain its nearly perfect spherical shape.
That...or its aliens.....

Gravel is being dumped from a conveyor belt at a rate of 50 {\rm ft}^3{\rm /min}. It forms a pile in the shape of a right circular cone whose base diameter and height are always the same. How fast is the height of the pile increasing when the pile is 16 ft high?

edit : its 50 ft^3/min
>>
use the formula for volume a of cone, take derivative and set equal to defined constant, use implicit differentiation to get the height from there, which of course is a function of time and thus can be differentiated
either that, or could actually read your fucking calculus textbook
>>
>>8480218
Height/Volume * Volume/Time =Height/Time
Volume= 1/3*pi*1/4*Height^3

He was a fucking lunatic who snorted coke, fucked women all day, and made up wild theories as to why humans behave the way they do.
In the realm of psychology, the only thing that truly stuck from him was that of psychotherapy. Even this is thought of as being shit in modern psychology.
Like other psychologists of his time, his work lacked the merit of being disproved. Read into many other psychologists conjectures, and you'd be hard pressed to understand why a particular person did what they did.
He's just a meme.

Should scientists get more media training?
Speaking from personal experience, I think they should. A while back I authored a high profile paper, and was subsequently approached by journalists. In interviews I didn't want to sacrifice accuracy for simplicity, which resulted in a few newspapers publishing things that completely missed the point of the article or were simply wrong. I've learned from this experience, of course, but I think a little bit of media training could have prevented the whole ordeal.
Moreover, as is quite clear at the moment, scientists are simply not vocal enough when it comes to important issues. For instance, if many scientists would openly speak out in the press against Trump's stance on climate change, it'd be harder for him to get away with blatantly denying what is scientific consensus.
We need to be able to communicate our findings to the public, so it seems strange that we never formally learn how to do that most effectively.

Lucid dreaming comes to mind.
>>
It's a really interesting concept. I've had it where I've spoken with my subconscious in my dream. Generated a version of myself infront of me and had long winded conversations. Can usually do it everytime I'm in a dream.
Keep in mind I've been lucid dreaming for 3+ years at this point so it's very vivid and controllable but definitely obtainable.

When I was a kid we'd get weeks of -20 to -30 temps. Now it happens maybe once a winter, it's not even enough to kill the pine beetles anymore.
Yeah I know weather isn't climate, but the change is noticeable.

If pure mathematical problems tend to be more difficult and require a higher IQ than theoretical physics problems, then why are pure math people usually dumber than physicists?

Alot of futurist are confident that the Technology singularity will happen in the next 30ish years.
If this is true then until then...
> what do?
I'll be in my early 50s by then.
Should I just keep myself alive until then and follow my dreams while I can? Because none of that shit will matter when the day hits.

Hello. I am Tenjin, the God of learning. I will grant you one skill you wish to aquire. However, you must be specific with your choice as it will increase the chance of the wish being fulfilled, if you are too vague, then you will likely get nothing. For example, saying Arts will yield a 10 percent chance of success; drawing, 50 percent; drawing manga, 80 percent etc. I cannot tell you the exact chances that your wish will succeed, only you will know yourself. And remember, I am the God of learning which means I can only grant you skills that can be learned, I cannot turn back time, or grant you superpowers.

Basically still unsure, but it's correlated with low grey matter volume, changes in connectivity, lesions on the brain, etc.
