Exactly 400 years ago today, the Italian astronomer and philosopher Galileo Galilei showed Venetian merchants his new creation, a telescope the instrument that was to bring him both scientific immortality and, more immediately, a whole lot of trouble.
It is 400 years since Galileo Galilei demonstrated his telescope, which
would lead him to make new astronomical observations. While many people
have been loudly celebrating this year's double commemoration of 200
years since Charles Darwin's birth and 150 years since the publication
of On the Origin of Species, another scientific anniversary has crept
up relatively quietly, marking an event which arguably changed human
thought and the way we see ourselves even more irrevocably.
