"He did this by setting up a series of paradoxes that showed, among other things, that half a given span of time is equal to twice that given span of time, that time and space are neither continuous nor discrete, and that nothing ever moves. Ever."

None of those things are true. One minute isn't equal to four minutes, Zeno didn't prove anything about time and space being neither continuous nor discrete, and things clearly do move.

The only correction I'd make to their sentence is change "showed" to "appeared to show". And his paradoxes did appear to show all those things. Of course empirically you (and the ancient Greeks) could see that they must be wrong - the challenge was to find the logical flaw in his arguments. Finding that took a very long time.

Perhaps I'm being overly pedantic, but in my mind "showed" and "appeared to show" mean very different things.
