Thanks for Explaining! – Twisted Light

The Bunsen Burner has an interesting story about using twisted light to transfer data. For the technically astute, they had the following statement in the story:

Previously it was revealed that beams with different orbital angular momentum (OAM) states — different degrees of spin — could be used to carry more data, and this new milestone builds on that idea, said researchers.

So if you were not familiar with the concept of orbital angular momentum (OAM), now you know what it is. It is just a technical term for different degrees of spin. Whatever that is. I guess that spin is a term people are more comfortable with, since many science-oriented layman will have seen the term, (maybe since it is discussed in A Brief History of Time.) No one knows what it is, but they take it as an explanation for a yet more obscure concept.
