Galileo instructed his students on how to make horoscopes
It's strange to think of the founder of modern science dabbling in astrology. But two things should be kept in mind: First, historians warn us that judging historical events by today's standards is tricky. We all know that astrology is nonsense, yet astrology was only just beginning to separate from astronomy at the time of Galileo. Besides, Galileo was not wealthy: A professor who can teach astrological methods will be more in demand than one who cannot.
