Math geek sighting

Today at North Station I spotted a guy wearing a shirt that said:

I {r = 1-sin θ} Math


r = 1-sin θ is an equation for a heart-shaped curve. Sincere math geeks recognize it on sight, and realize that the shirt is saying, "I [Heart] Math".

Well, I thought it was funny. :-)

(Edit: changed "th" to "θ", now that I know it's working--see thread below if you care.)

Argh. It showed properly on my screen. That dash is a spade as in suit-of-cards.

It showed properly here.

Though the t-shirt in the post itself threw me...maybe I would have gotten it if it'd been 1-θ rather than th....

John reported that he had the same problem -- that the theta he put in didn't 'come through' so he changed it.

We both pulled the symbols from OpenOffice and pasted them in. Odd that they show variably.

It may have to do with unicode support. Using ♠ and θ might work better: ♠ θ

Hmm. No spade showed up, just a dash. The theta showed up, though.

I'll have John think on it.

In fact, I did use θ, but it didn't show up for me--and still doesn't. Since the spade does show up, I think I know what's going on: there's some font I have installed that has something other than theta in the theta slot. (Since you can't expect the user's chosen font--or, perhaps, any font--to have all Unicode chars, Mozilla combines fonts to make a virtual font with as many Unicode chars as it can. When fonts lie about what characters their glyphs represent, Mozilla has to believe them.)

Re: Unicode
screw up

Hunh. θ really *ought* Just Work(tm). Ah, well.

It might also be your browser's choice of text encodings that are messing things up...

Re: Unicode

<dig, dig>...no, I was right: there were some Syriac fonts that had usurped the Greek codepoints. I removed them from my system, and now things look right.

Arrgh--that was me. I still can't figure out why LJ keeps logging me out at home. It doesn't do that at work.
