Well, the real fun is deciphering a lower case xi - ξ - when written on the blackboard (or whiteboard), specially compared to a lower case zeta - ζ (fortunately way less commonly used).
As all the others already told you. you don't learn by reading alone.

- contravariant 5y agoAh, yes. I remember the time when I saw someone write something vaguely like the following [0,ξ[={x|0<=x<ξ} Which was fun trying to figure out when written in handwriting where ξ,{,} all look the same. If you can't figure out what it's supposed to be, this equation starts with a half-open interval denoted: [ξ,0[. This notation has some advantages but can be make things hard to read.
