They are increasing the precision of the phase while decreasing the precision of the amplitude. Since the amplitude of the light determines how hard it pushes on the mirrors, this has the side-effect of also making the positions of the mirr

I think the key point here is that selection for form need not be intentional. Taller plants are able to collect more sunlight, and collecting more sunlight means they are more likely to have many descendants. This does not happen because s

Yes, the engine of selection is just survival and reproduction. This, combined with random mutations is pretty much all you need for evolution to happen. In an artificial environment, survival and reproduction can be affected by humans, but

Even the sigmoid is a somewhat optimistic picture. Another possibility is a bell curve, where due to resource depletion we eventually end up back near where we started. It's interesting to imagine how over time the scientific knowledge

Sure the experience of being dead isn't too bad, because there is no such experience, but consider this: Thanks to the arrow of time, you can know what happened in the past, even if you weren't personally there. Many details are

When I first saw the title, I thought it had something to do with this: https://en.wikipedia.org/wiki/Penrose_graphical_notation . Looks cool, though.

I'll answer 2. You are correct that clocks just to either side of the throat will stay synchronized. But it's important to remember that time dilation isn't some kind of absolute effect. The easiest way to talk about it is in

Not an expert, so take these with a grain of salt: The core of the star is the hottest and most dense part. Greater heat and density make it easier for fusion reactions to run. If suddenly the core is made mostly of iron, then the amount of

I'm surprised that it's even necessary to modify the dataset to achieve this. From what I've read, large models will often memorize their training data, and it seems like even with smaller models it should be possible to tell

Not quite. The formula you gave is the more general one, the previous one assumes that all microstates are equally likely. Given that assumption they are equivalent though.

Here's another thing: I remember learning that all the nice usable energy we get from the sun is due to the fact that the big bang produced lots of hydrogen, but fusing four hydrogens into a helium yields a bunch of energy. (And you ca

According to Baez, all the matter fields and radiation fields were in equilibrium at the big bang, so by elimination the answer has to have something to do with gravity (which is, after all, the force driving the formation of the gas clouds

Interestingly, there actually is such a concept as negative temperature. It applies to systems that have a maximum allowable energy as well as a minimum one. Such systems must be isolated from the outside world, and set up carefully, but it

This is not the full explanation, as can be checked with a simple experiment. Dip a piece of cloth in a glass of water and hold it there submerged beneath the surface. The submerged part will still look darker than the dry part, despite the

Fusing 4 protons into helium definitely happens in the sun, where protons are the most common hydrogen isotope. Most fusion on Earth is done using the deuterium-tritium reaction, which produces helium and a neutron. The reason is that it&#x

On the contrary, I would say that it makes a large difference whether someone interrupts me because they have understood the idea I was trying to communicate, or because they never cared about that idea in the first place.

I tried it out. As other commenters have pointed out, it doesn't produce much of a coherent story, but it does have its amusing moments. For example: THE DOOR NOW HAS THE LETTERS "ME" WRITTEN ON IT go through door I

Just for the record here: I think it's a good thing when people are willing to admit they're ignorant about certain things. It shows that they are willing to learn and change their minds based on new information.

Speak for yourself. I personally prefer to evaluate the statements of scientists on a claim by claim basis.
