The 2nd partial derrivative of u with respect to t (time?) is equal to 
the square of the wave velocity multiplied by the Laplacian of u.

What the heck is a Laplacian when it's at home?

Oh, wait - it's a second-order differential operator in the N-dimenional 
Euclidian space defined as the divergence of the gradient. Obviously.

._.

Ouch.

Wikipedia - a great reference source, a rubbish way to learn brand new 
concepts. (Indeed, I've seen articles marked for revision *because* 
"Wikipedia is not a how-to". Hmm, what *is* Wikipedia then?)
