Fine-structure constant

Fine Structure Constant Explained in 60 Seconds (Part 1) #shorts by Parth G

#shorts - the Fine Structure Constant (alpha) is a fundamental constant of nature. It is often known as the coupling constant of the electromagnetic force, and is dimensionless, with a value of approximately 1/137. It shows up a lot in the mathematics behind physics, but there's a reason

Visualizing the Fine Structure Constant (Part 2) #shorts by Parth G

#shorts - here's a really fun way to visualize the Fine Structure Constant, often given the label "alpha". It happens to be equal to a ratio of two very particular energies, which in this video we've called E1 and E2. E1 is the energy required to bring together a pair of electrons (initi

We now discuss how, given a structure and a basis, we can predict the spacing, position and magnitude of the intensity. We find that, in practice, we have no idea where atoms sit in a lattice. So we take a guess, use the structure factor to calculate the intensity and compare that to exper
