Indeed there is, as Lachlan almost immediately pointed out:

Not much I can add to that.

Actually both are redefined to be media-independent in HTML5.

As was pointed out in the original thread, the name doesn't convey 
semantics, the element and its definition do.

Certainly.

As was later pointed out, <em> is the appropriate element here. Shouting 
is an extreme kind of stress emphasis.

There is one problem, which is that user agents incapable of showing the 
original element's default style (e.g. a text mode browser with no font 
size control, or a speech browser, or a braille browser) has no guidance 
as to what to do with the contents. On the other hand, using a semantic 
element like <em> allows the user agent to intelligently substitute the 
original recommended rendering with an equivalent rendering that it can 
render on its medium.

I disagree; <em> is appropriate here.

<strong> in HTML5 represents importance, so I agree that it is not 
appropriate here.

Mathematics are indeed a thorny problem. It's unclear that <big> would go 
far enough in solving it though.

Indeed.

In HTML5 <em> and <strong> are orthogonal in definition.

Right.

Indeed.

Indeed.

Indeed.

CSS doesn't define meaning, only presentation.

Indeed.
