Rare Greek Variables

Back in physics grad school it surprised everyone else that I not only pronounced 'ξ' as "ksi" rather than "cascade" or "squiggle" but, more amazingly, could actually write it like ξ rather than a squiggle... I still don't really get why that's impressive.

The trick to writing ξ is to notice that it is a fast/sloppy cursive way of writing three parallel horizontal bars (Ξ).

Well, Cascade is the name of the particle, not the symbol... (and it would normally be upper-case, no?)

for non-physicists: https://en.wikipedia.org/wiki/Xi_baryon

Also, for this reason, surprised it's one of the more rarely used Greek symbols...
