Listen I know we need a lot of variables in math. A single alphabet won’t due. So capital and lower case letters can be different variables. I can even roll with the idea that letters of the same case in different *typefaces* can be distinct— but, I still find the abusive use of C in Hoggs Mathematical Statistics a little extreme… we couldn’t get more distinct typefaces? How many students have cried because you did this, Hogg? (i otherwise love this textbook it’s so much fun) /math rant

@futurebird yeah if you really need to use the same letter just use another alphabet, Greek, Russian…

@galoisghost @futurebird This reminds me of the professor at university who used Hebrew letters when he ran out of latin ones. The pattern detection part of my brain had multiple breakdowns because of that guy. ;)

@zappes @galoisghost I love it when some alphabet other than Greek gets a chance to shine in math.

@mina @futurebird @zappes @galoisghost This math will only lead to more math. But that's all good math right?I love your list.

@futurebird do they charge mathematicians by the letter, I always wondered.

@adriano It’s kind helpful they are all c since they go together… but we could use a less plain script font— except the common script font is already used for the set of complex numbers in the book so… IDK. I guess dude was like better break ‘em on the first page with a blizzard of Cs — it’s a wonder students take us seriously after that.

@futurebird @adriano when I tutored college students, most of them had a hard time learning to view different typefaces as important in mathematical and physics texts. And in those days when hand-written notes were the norm, consistently reflecting typeface differences in handwritten notes was a real struggle for many.

@llewelly @futurebird @adriano even when you're taking notes on a laptop how on earth do you quickly type both those upper-case variants and keep them distinct from plain old C?

@DrHyde @futurebird @adriano honestly I have no idea, but maybe that's because I learned to use computers before support of multiple fonts became normal.

@llewelly @futurebird @adriano I've set up my keyboard to include all the mathemagical symbols I commonly use as well as funky alphabets, so I can type rRρΡℝ, but if a new symbol comes up in a lecture it won't be configured yet. Argh! And even after I have added it, it's still going to be slow to type (Ρ is seven keystrokes - § shift g r r h o), and I have to remember that the new character is called §Citalic or §Cscript, and spot the subtle difference on the whiteboard correctly every time.

@DrHyde @mina @llewelly @adriano I spend some time programming my keyboard, though I wish I had legends with all the layers. Here are my last two set-ups. Currently on the blue one. Love how easy it is to reach everything. I made the orthro from a pcb... though never quite got it doing everything I wanted correctly. Maybe I'll try again some day.

@futurebird @DrHyde @mina @llewelly @adriano Oh my goodness. I was beginning to think I was the only one using an ortholinear design. I used to have quite a lot of hand pains from doing so much typing all the time and was convinced to switch to Dvorak and try the TypeMatrix in part because of its hardware Dvorak switch (as a gamer, software-controlled layouts are a problem) then when that eventually died I built a keyboard on a generic Idobo 75 clone. Haven't ever looked back.

@futurebird I've seen much worse than this in computer science texts. Instead of different fonts or cases, I've seen a single formula with 3 different occurrences of italic lowercase "t" with 3 different meanings. You're supposed to be able to tell which is which.

@futurebird but how else would you express the relatedness of those different types of C (the similarity of the fonts of those two capital Cs is not on though!)

@futurebird @projectgus I once attended a workshop by M K McKusick one of the key architects of BSD Unix. He told a story about people pestering him to increase the limit on filename length. His reply was “once you have put 1024 characters into the filename, consider maybe putting some data in the FILE!”.Once you have used every letter in six alphabets, consider maybe TWO LETTER VARIABLES!

@futurebird Try to distinguish in handwriting between X, a separable Hilbert space over the field 𝕩, whilst 𝓧 is a collection of such spaces, x an element and 𝛘 a linear functional on X.Slightly besides your point, but I love this Greek letters chart by xkcd:

@futurebird In this case, I think that Donald Knuth is the guilty party, because he had chosen a script alphabet for TeX that insufficiently differs from the standard alphabet.Pro-tip: Have \usepackage{eucal} or even\usepackage{mathrsfs} in your LaTeX preamble for squirlier script letters.
