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...

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?

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.

No. While they are electromagnetic phenomena, light waves themselves have neither electrical charge nor a magnetic moment.

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)

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?

>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:...
