these ancient ‘scientists’ had good reason to be wowed by their
achievements. Its amazing power was being made manifest in
the construction of the Parthenon – a technological wonder
that has inspired awe for 2500 years.
One should not underestimate the remarkably prescient
nature of their discoveries too. Parmenides realised that the
moon refl ects the light of the sun. Democritus postulated the
basic units of nature as atoms existing in a void. Pythagoras,
who may not have originated his celebrated theorem, may have
