1 The most famous text influenced by Democritus is De rerum natura (On the Nature of Things), the didactic poem in six books by Titus Lucretius Carus (99 BCE–55 BCE), a poet of the late Roman Republic and a follower of the Greek philosopher Epicurus, who had taken up Democritus’s atomic theory.
2 The sprawling tale begins in ancient Greece, with the origin of atomic theory.
3 Before atomic theory—which states that all matter is made up of tiny particles called atoms—people didn’t have a good idea of what matter really was.
4 But Rovelli says that the degree of confirmation of atomic theory shouldn’t even be measured in the same units as that of string theory.
5 String theory is not, say, 10 percent as confirmed as atomic theory; the two have different statuses entirely.
