It is not faster than light.
I think what he wanted to show was a situation, in which entanglement and quantum mechanics, are superior to classical physics. i.e someone using quantum mechanics would have an advantage over someone who don't.
However, as he said, in this situation the two generals could have agreed on something else, like if it was raining or not.
In fact, something they could have done is to flip a coin, and split with a copy of the result, which they only look at when they launch the attack. It would have the same effect.
With a random variable (the coin flip), that is hidden until revealed, we achieve the same results as quantum mechanics.
Scientist call them "hidden values" and Einstein hopped we could explain the "spooky action at a distance" with such hidden variables. But we can't, Bell proposed an experiment with entangle state which measurement could not be explained by such hidden variables, and Aspect did the experiment and obtained the predicted results.
So there exist situation where we can use entanglement to achieve better results, for example in "non-local games", where players sharing entangled state can win with probability 1, when "classical player" with probability < 1

Yes but the difference is that in this case, the plan already exists from the moment the coin is flipped until the result is revealed to the generals. In the QM case no one (not even God) knows what the result will be until it is actually measured,but once that happens the result is known "instantly" at both places (assuming both coins arrive at the same time), so in that sense is a FTL communication (of course it is not real communication)
“ So there exist situation where we can use entanglement to achieve better results, for example in "non-local games", where players sharing entangled state can win with probability 1, when "classical player" with probability < 1”
Do you have an example for this? This is really interesting
Not really, maybe it was the case 50 years ago (I don't know). Now I'd say the authors that are the most well known in France are Victor Hugo, Molière (we say that french is Molière's tongue), Voltaire and La Fontaine (every student has to learn some of his fable), maybe Baudelaire.
But then again, even tho most french people heard/learned about them, few could quote one of those author.
As for an equivalent of Shakespeare, Pushkin, Goethe or Dante, we don't have any author stamped "best French author", it's a matter of personal opinion I guess. I'd say maybe Proust, but not a lot of people read him. (There is a saying that half the people who say they read Proust, did not).
For things like textbooks, I'll start easily but then, when I reach a new point or new chapter, I will rationalized my self to stop it there and call it a done work, when in reality I worked only 30 minutes instead of and hour.
it's like my mind is rationalizing itself to settle for a sub goal.
That's where the Pomodoro technique might be useful. If one adheres to it, it does what the article describes as "making the decision in advance." After you take a break after the stopping point, the technique makes you continue on. But of course, that means you have to embrace the plan and not resist against it, either.
Honestly I don't think your argument really hold. When you are born in place were you use a specific system of mesure you get use to it. And I don't see how living beetwen -10°C and 30°C or 10F or 80F change anything.
It's not always positive. Because of our large brain we must give birth before the child is fully develope and then it take 15-18 year for it to become adult, before that the child is pretty weak.
One might see this as a positive feed back loop. One thing a large brain is really valuable for is having ideas about the future you want and then acting in the world to achieve that goal. The farther in the future your goal is the better brain one needs. Thus having to raise a child successfully for a long period of time will help evolve even bigger growing brains and longer childhoods.
On the other hand, maybe humans are now breaking this restriction as more and more births are by C-section. I could see a future where most births are that way (if we don't get artificial wombs first).
"All signals with content entirely below the Nyquist frequency (half the sampling rate) are captured perfectly and completely by sampling; an infinite sampling rate is not required. Sampling doesn't affect frequency response or phase. The analog signal can be reconstructed losslessly, smoothly, and with the exact timing of the original analog signal."
Analog reproduction is far less complex and easier to explain in pictures to an unknown entity that might find it. Figure that they'll need to build what effectively amounts to a record player to play the thing back. In addition there was no digital technology of the time with a large enough capacity to store what we sent, or that was durable enough to deal with an unknown time in space.
Quality of the reproduction is not a consideration.
What a nice trilogy, when I read it I had the feeling that there was really a colony on Mars. I still have music which I listened at the time that trigger a martian feeling !
It make me think of Von neuman probe. If we can consider that a robot or something with connections similar to our neurons can be a living creature. Then maybe if something like Von Neuman probes existed it could have colonized the whole galaxy (actually it could be done in a few hundred millions years) then those probes, while each one have is own brain, could communicate with the other probes and even if two probes at two opposite sides of the galaxy couldn't communicate, they would still be connected. Then maybe this network could be consider as a living creature.
I personally use KeePass, I generate 20+ character random passwords and it save them in a encrypted file. I just wrote my email password and hide it in case I lose my file.
I also use KeePass to generate long, pseudo-random passwords. The amount of different passwords I need is far beyond what I can hold in my head, especially when they have to be secure. I got my closest family to use KeePass too, which lead to a significant reduction in lost passwords and hacked accounts.
