Like what? The Greeks advanced science and mathematics. The Romans sacked Greece and pillaged their artifacts. They didn't advance science or mathematics at all. Rome was a 1,000 year dark age.
Yours seems to be one of those opinions that can be summed up as "lol Greeks good Romans steal" when there is no shortage of technology and civil law improvements the Romans brought to light. To mention a few: a senate, aqueducts, urban planning, sanitation, civil engineering much better than that of the Greeks (see domes and arches), many ideals that are still present in today's governments, farms of quasi-industrial level production, and so forth.
That the Greeks made more developments in Maths is true - it was more of a cultural thing anyway. Your post also completely ignores the fact that Greece flourished under Roman rule and managed to keep many of its freedoms, with the protection of a giant empire. Romans also distributed Greek texts to all corners of the known world, wherein learned people could be found.
Your comment seriously sounds like that of a child, not at all something of the level of HN.
Rome existed for more than a thousand years, and for five hundred of those years there was only an emperor (who didn't refer to himself as a king). I will give you that Rome was good at building but that doesn't stop it from being a dark age. And while Greece was mostly left alone they did not "flourish" and their output significantly decreased. The Romans were anti intellectual and cared more about their traditions than understanding the world. That's why the Romans used Greek statue building techniques to make status of themselves and of the Emperor instead of the gods like Greece did. To Romans they were their own gods. They didn't care about the natural world or about philosophy. They actually became better at statue building than the Greeks (after hundreds of years) which would probably be listed by you as a "Great Roman Achievement" but it's just the result of Aping Greek culture. The Romans themselves were in a sense aware of this; they would use Greek in official documents and would at times dress up in Greek Togas/Chitons. Caesar's Et tu, Brute? was actually spoken in Greek.
