Primes

Prime symbols are quote-like symbols that can be used for different purposes in different fields of study: from indicating mathematical units, to musical notation, to specific ways of pronouncing letters.

There are many prime symbols:

• Single ′

• Double prime ″

• Triple prime ‴

• Quadruple prime ⁗

• Their reverse equivalents (‵, ‶, ‷)...

And HTML has ways of representing them as single characters:

• Prime: ′ or ′

• Double prime: ″ (notice the capital P) or ″

• Triple prime: ‴ or ‴

• Quadruple prime: ⁗ or ⁗

This cartoon shows how to write some prime symbols and finally introduces a "new" one: &oprime; that generates the silhouette of Optimus Prime from Transformers.

I was thinking about posting this cartoon next Tuesday and make it coincide with April's Fools. That way make the "double joke" of the cartoon plus insinuating the the W3C announced a new HTML symbol... and you wouldn't believe what it is!
