OK. Every now and then I hear of some old Greek fragment that was "ahead of its time", and it's gotten to be a hobby to collect them.

I think it's actually interesting to figure out what things the Greeks hadn't figured out in their time -- possibly a much smaller set. They didn't have algebra (e.g., the quadratic formula eluded them), and something must have happened after their time, to bring us modern empirical science.

Still it remains impressive to me what they were able to accomplish without modern tools.
