I came here for the sweet chill bass.

Light moves at a defined speed through a vacuum. However when passing through a material, the photons of light interact with the atoms of the substance and are absorbed and re-emitted. There is a short pause between the absorption and re-emission, so light APPEARS to be going slower, but the photons are actually still going the same speed in between the atoms.

0:13 looks like a dalek

Maybe traveling faster then the speed of light could be called a photonic boom

Could you explain neutrinos in relation to beta-decay?

What exactly do you mean by "left-handed" and "mirror image"? It's kinda confusing if you explain it with an analogy, but don't talk about what's actually going on.

Oh k nice.

Because in traditional vampire stories (e.g. Dracula) vampires don't have a picture in the mirror, unlike a normal human.

Just like neutrinos, they don't have a version rotating in the opposite direction, unlike all the other particles.

im gonna cry... my brain hurts to much .-.

Fuck being a firefighter, I wanna be a physicist mom!

[Paulo Andre Azevedo Quirino]

what do you mean the vampires of physics? Why do they suck? Haha. No, really?

[TheAnonymus2012]

because light was the first thing to be known to move at that speed. the correct term is actually speed of electro-magnetic waves, but that is to long.
