Albert Einstein thread.
Post questions about him; suggest books, documentaries, or any other information about him and discuss his life and work.
I have some questions I would like to ask:
1-Let us imagine that Einstein was never born. Is it possible to say that his theories would eventually bloom by the work of other minds in a period of 20-30 years? Or his insights were so unique that we cannot say for certain how much time would pass without anyone reaching them?
2-What is the best book about his life? I know the famous Isaacson one, but I guess there must be some more complete texts.
3-What do you guys think of this Eugene Wigner definition:
>“I have known a great many intelligent people in my life. I knew Max Planck (Nobel Prize 1918), von Laue (Nobel Prize 1914) and Heisenberg (Nobel Prize 1932). Paul Dirac (Nobel Prize 1933) was my brother in law; Leo Szilard and Edward Teller have been among my closest friends; and Albert Einstein was a good friend, too. But none of them had a mind as quick and acute as John von Neumann. I have often remarked this in the presence of those men and no one ever disputed me.
>… But Einstein’s understanding was deeper even than von Neumann’s. His mind was both more penetrating and more original than von Neumann’s. And that is a very remarkable statement. Einstein took an extraordinary pleasure in invention. Two of his greatest inventions are the Special and General Theories of Relativity; and for all of von Neumann’s brilliance, he never produced anything as original.
All I want in life is to be good at math and physics. It's all that I want and I am just not good at them. It is absolutely devastating to me. Have any of you ever climbed out of this pit of never being able to do what you truly want to do?
>>8174229
If you want to be better at physics and math, the only way is by doing more physics and math. Exposing yourself to more concepts and problems is a very effective way of getting out of this rut. Good luck!
>>8174229
Si. I realized that I was just being spoiled.
>Boohoo I don't get to do what I deem most important because I'm not gifted enough
Every small contribution counts for something, even if it is invisible to others, and maybe even to yourself. Get over yourself. There are plenty of other ways you can contribute to the world, and doing so shouldn't necessarily be what you _want_ it be or even make you feel good about yourself.
You can't always get what you want, and you need to get over that.
How does one pass the Van Allen belt?

>>8174124
By going through it. It's not like it's a HUEG WALL OF DEATH.
For best results don't pass through it during a solar storm.

Why are people so illiterate when it comes to science and how do we stop this?
There's a fundamental flaw in humans.
The only cure for this flaw is a total destruction.
>>8174122
Welfare requiring irreversible sterilisation would do the trick in five to ten generations.
>>8174122
yeah this is pretty sad, not surprising but sad
help sci
For two days now my ringfinger and pinky are numb, start with a stinging under my shoulderblade going down my arm it becomes a tingling sensation.
I tried sleeping on my back, getting exercise, stretching the fuck out of my back but it seemed to only make it worse :(
what do I do now, I have to wait 12 days for my doctors appointment but it gets worse every day!

Sign of diabetes or imminent heart attack
ITT: We discuss the application of neurobiology in improving martial arts offensive and defensive capabilities.
My first topic is: Could you cause cardiac arrest by stimulating the vagus nerve, sending them into vasovagal syncope, whilst rapidly striking the cardiac muscle itself?
>>8174061
>Could you cause cardiac arrest by stimulating the vagus nerve
Yes, and it's nothing new. Some judō choking techniques do just that.
>>8174061
You can cause a heart attack by just punching someone in the chest at the right time.
>>8174074
Seems a bit like overkill, considering they're already probably entering syncope, which normally results in unconsciousness. Do you agree?
Can magnets bend light rays?
>>8173941
No. While they are electromagnetic phenomena, light waves themselves have neither electrical charge nor a magnetic moment.
In other words, light rays pass through (static) electromagnetic fields just fine without interference.
>>8173941
They can however rotate the polarisation axis of say linearly polarized EM waves.
>>8174010
Faraday rotation.
Am I the only one who gets mad as fuck when observing this world?
There are jews that make at least $100k a month from stupid HTML websites by charging $10k to people.
There are mathematicians/engineers/physicians that work hard to make world the better place and discover new stuff, they dont care about stupid yachts or big houses
There are idiots that make billions of dollars from simple shit like selling food, making minecraft (LOL)
So my question /sci/ is : Is money high score of dumb people?
>>8173909
> Is money high score of smart people?
Its nobody's fault that you grew up not knowing basing money working.
It should be rudimentary subject in primary and high school instead we are teaching kids how many sheep Australia has.
I am only realizing this at age of 25 and I deeply regret not giving interest in economy at a younger age.
>>8173953
>basic*
>>8173953
So basically, if we let go of our desire to know more, we will get rich because there will be other idiots willing to spend hours learning something new just so that we can collect all the cash while he still gets paid his regular monthly salary?
What kind of bodily reaction makes sneezing feel so strongly euphoric? Is it strictly a local reaction in the nasal area or does it also involve the release of certain neurotransmitters in the brain?
To me sneezing is so rewarding that I often manually induce it by stimulating the nostrils with a piece of toilet paper with the corner rolled up into a thin spike. What makes it so rewarding that I would want to continue sneezing repeatedly as long as I can?
Also, does it provide health benefits to sneeze manually every day? It releases tons of snot so this can be only positive, right?
Please answer.
Surely this has been studied extensively?
Tension/ release. It fulfills an urge. Holding your piss all day and taking a massive piss doesn't feel good, it feels good relative to the intense urge of having to piss.
Why do we find furry things cute?
>>8173840
I don't, some are, some are not.
Because they have features similiar to babies.
>>8173840
Social constructs.

Gauss, thanks.
Why there is no flow of electrons if i connect the positive terminal of a battery to the ground/PE (protective earth) of the mains?
>>8173794
you have an open circuit
earth ground is just a zero reference (and return path) for AC power distribution systems.
>>8173803
Would'n there be enough free electrons in the ground/earth that a few of them would move to the positive terminal of the battery where is an abcence of electrons?
Maybe they do.
Who's vaccine program has helped the most citizens.
>>8173715
Polio.
Nearly erradicated until the vaccine scare in Nigeria.

The one that triggered millions of kids to develop something known as autism.
What is a precise definition of entropy?
What is a precise definition of information?
Why does entropy increase with time?
Why cant we remember the future?
>>8173706
well?
why does Google exist ?
>>8173706
>What is a precise definition of entropy?
It's a measure of disorder. The higher the entropy, the more disorder in your system. Suppose you have an ideal crystal that can be displayed with three base vectors and one translation vector. You could scale up the crystal as much as you want in an ideal crystal, all points or "nodes" have always the same distance to each other. Here entropy is zero. Now go into the real world, where the positions of those nodes vary: you have "chaos", entropy increases.
>What is a precise definition of information?
Depends. CS people will say something different than physicists. Usually information is a coordinate. Where is a point? How does it move? Everything is essentially a problem of geometry.
>Why does entropy increase with time?
Suppose you have a closed system with two different gases. Both different gases have different temperatures. According to the 0th axiom of thermodynamics those gases will try to get into a thermodynamic equilibrium, meaning both must have the exact same temperature or energy. In a closed system this can never happen and particles will get more and more disordered as time passes.
>Why cant we remember the future?
?
explain to me what the fuck this is, /sci/
Pretty sure it's a Riemann sphere

this
[th is]
pronoun, plural these [th eez] (Show IPA)
1. (used to indicate a person, thing, idea, state, event, time, remark, etc., as present, near, just mentioned or pointed out, supposed to be understood, or by way of emphasis):

>>8173735
while this is pretty much /thread, does anyone else wonder what
's gonna happen if we crawl through definition of the english word? Like how long does it take before you end up in a loop or what word will reach the most word the quickest.
