### How to enter the "big epsilon" in LaTeX

There are two kinds of epsilons in LaTeX, $$\epsilon$$ and $$\varepsilon$$, which can be entered as "\epsilon" and "\varepsilon" respectively. So how about the "big epsilon" $$\mathcal{E}$$ which occurs often as the symbol for "energy functional"? It turns out, it's not an epsilon, but a curved letter "E". To enter it in LaTeX, simply do "\mathcal{E}".

That's a Roman E in script, not a 'big epsilon'. A capital epsilon is indistinguishable from an E, and presumably you'd want it to appear in the same font family as your other Greek letters.

Thank you so much! I don't care where it comes from, I'm no linguist! That's the character I need.

Many thanks for this. Irrespective of what it is typographically it is a better version of the symbol for electric field.
