You're right, I did not know that. Thanks!

Isn't // integer division?
Watch everyone forget that correlation doesn't equal causation when it confirms their biases.
Correction: You'd need to travel with a speed higher than the vacuum speed of light.
Has to be Debussy and Chopin for me.
Or Kenya, I guess.
But it's like triple the price of ramen or Yoshinoya - and that's the cheap sushi. Real sushi isn't a leftover recipe, it's an art by real chefs.
In Japan, sushi is definitely one of the more expensive foods. You can't really use yesterday's fish as authentic sushi uses fresh fish which you can't eat the next day for obvious reasons.
It does: Light does not follow the path of minimal distance between two points, but the path of minimal time. This is called Fermat's principle.
Because water has a higher refraction index than air, light is slower in it and therefore takes a longer time to travel through it. Thus, it takes less time to take a longer path that spends more time in the air.
Fun fact: The underlying law of this principle is the principle of least action. This is the most basic law of nature we know of and can be used to derive all of physics.
Currently, there is basically only one real world application we really know: Factoring numbers into prime factors. And we can't know for sure whether there will be more even.
