reminds me of this meme

Its a reference to a 20 year old meme

If cogwheels are counted then I think there are more wheels

c is the speed of light in a vacuum. It is impossible to send information faster than c. x-rays are also just light so everything I said before also applies to x-rays.

I'm not very familiar with how light interacts with materials since it wasn't covered in the electromagnetism class that I took, so the next part might be wrong. The speed of light is calculated by looking at Maxwell's laws of electromagnetism and recognizing that it is the equation for a wave. The speed is then calculated as c = 1/sqrt(epsilon_0 * mu_0) where epsilon_0 and mu_0 are the vacuum permittivity and the vacuum permeability. Inside a material, I think the permittivity and permeability are different and thus the speed of light as determined by Maxwell's equations would be different. I know its not possible for the speed (group velocity) of light in a material to be faster than the speed of light in a vacuum because otherwise, you could send information faster than c, which is impossible.

If you had a material with no light passing through it, then you shined a light through it, it would only move at the group velocity. The whole "faster than light" thing refers to the phase velocity, but you can't have a phase velocity if the light hasn't gotten there yet.

Saying that gamma rays (or any light in general) moves faster than light is technically true but very misleading and relies heavily on when you define "speed" as.

3Blue1Brown has a good video on why the phase velocity is different from the group velocity if you're interested in why. The faster than light phase velocity happens when the "phase kicks" are so delayed that the phase appears to move forward.

Its because "speed" can refer to two different things in this context. Group velocity is the speed that your light waves can send a message it. This cannot move faster than light. Phase velocity on the other hand is the speed of the peaks of the wave. This can move faster but its not possible to send a signal through this.

its because the meme sneakily saying more holes (volume) = more holes (percentage), then using transitivity of equality. This equality isn't allowed since the units doesn't match.

if you have krunner installed, you can also look for the definition by typing define wordyouwant

Isn't this just like the internet though?

its a vocal minority, don't pay them any attention

types in C are pretty weird

int *a can be read as

1. *a is a int
2. since dereferencing is a operator on pointers, a is a pointer to int

int *a, b is read as

1. *a and b are int
2. so a is a pointer to int and b is a int

bool getofmylawn(Lawn lawn)

1. getoffmylawn(Lawn lawn) is a bool
2. since calling is done on functions, getoffmylawn is a function that takes a Lawn and returns a bool

And then you have function pointers

bool (*foo(int a))(float b)

1. (*foo(int a))(float b) is a bool
2. *foo(int a) is a function from float to bool
3. foo(int a) is a function pointer from float to bool
4. foo is a function that takes a int and returns a function pointer from float to bool

really weird in my opinion.

Am i weird for using Y down right chiral on all my projects?

u-235 has a half life of 704 million years. only half of it would have decayed.

i thought this was a CAPTCHA until i read the title

!?!?

I seriously don't understand why he is doing this. Isn't trump friends with eslong musk? The way i'm seeing this is cutting the budget for nasa would only go against elon. If he wanted to save money, then he should have just cut military spending.

I got locked out of my old discord account because I didn't have a phone at the time

Suggestion the public is being manipulated

to me this sounds like they're trying to cover something they're doing up

I had to use unity game engine for one of my assignments for school, but unity wouldn't generate files needed for the language server unless I set the code editor to vscode. I fixed this by creating a bash script with the path /usr/bin/code that opens neovim in konsole.

#!/usr/bin/env bash
konsole -e "nvim $@"
