Take a seat, greek letters have uppercase & lowercase.
Now, take a deep breath.

and can you think of any of them where the difference between them isn't
merely size? Take roman letters like "H" or "h" and the difference is
remarkable. Not such with "lowercase" or "uppercase" greek (at least
the one's I know).
That's why I saw no difference in the pi symbol: I have no size to
relate to to tell if it's big or small.

How about:
Alpha, Gamma, Delta, Zeta, Eta, Mu, Nu, Xi, Pi, Sigma, Upsilon, and Omega?
You also get less drastic changes for: Beta, Epsilon, Iota, Lambda, and
Phi, plus some minor changes even for many of the remaining letters.

Oh, it's better: The entire Greek alphabet has uppercase and lowercase! :-P
(Although I surprising number of Greek letters, especially uppercase
ones, look exactly like Roman ones...)

Lowercase sigma looks like a "6", but the uppercase looks more like...
well, you've seen it, right?
Uppercase mu is an "M", but the lowercase is the "micro" symbol, that
looks more like a "u".
I could go on... GIYF.

Probably ;)
Actually no, because to ask google you need to know what it is.

This always amused me at school.
"I don't know how to spell X."
"Well look it up in the dictionary then!"
"But - and I refer you to point #1 - I DON'T KNOW HOW TO SPELL IT! >_<"
Still, usually when I state here that something cannot be Googled,
usually somebody immediately points out how to Google it...

I find that Google is good for getting the correct spelling.

Maybe people are ignoring you saying that something cannot be googled
and read it as *you* cannot google it. They then show you how to google it.
