yay, new notation. I was as equally excited by the d'Alembertian, square as it is.It can be represented by either [itex]\nabla^2[/itex] or [itex]\Delta[/itex] and technically it should be [itex]\Delta f[/itex] but I left it out because I am in fact quite mad/evil.

my simpleton contribution to this thread:

I was very excited when (during the course of my education)

[tex]F = ma[/tex]

evolved into

[tex]F = m \frac{d^2x}{dt^2}[/tex]

and further to

[tex]F = \frac{dp}{dt}[/tex]

I really like the continuity equation too:
