The Life of Galileo
We step into Galileo's life as his brilliant mind is focused on a trivial and mundane matter - paying the milk bill. Somewhat impecunious, Galileo is forced to take on fee-paying pupils and attempts to squeeze a higher salary from his university employers. But even in the 17th century, it seems university professors were expected to pay for their keep by inventing saleable technology. "Knowledge is a commodity", says the University Chancellor, "do not despise the market".
So Galileo purloins a Dutch invention - the telescope - enhances it, and duly hands it over to the university authorities in return for a higher salary. But the telescopic innovation has an added bonus for Galileo because it enables him to observe the moons of Jupiter and to prove the heliocentric theory of the universe - something which Copernicus had not done. Risking the antagonism of the Church, Galileo is convinced that 'reason' will prevail. Although the Papal Astronomer duly confirms Galileo's observations, he's nonetheless prohibited from publishing his discovery, and it's not until a new Pope - a scientist - is enthroned that Galileo becomes confident enough to recommence his work on planetary movement, but his hopes are dashed when he's subjected to Papal Inquisition and 'shown the instruments'.
