Could really smart people be wrong?
Galileo Galilei has been called the "father of observational astronomy", the "father of modern physics", the "father of the scientific method" and the "father of modern science".
With so many titles you would think that he could never be wrong, right?
Galileo didn't believe that the moon was responsible for tides. He thought it had to do with the daily rotation of the Earth around one axis and the yearly circuit around the sun. It took another 100 years to prove him wrong when another MegaGeex, Issac Newton, discovered the law of universal gravitation to explain how the moon's gravitation affects the tides.
Oh, but we're pretty sure he knew the multiplication of 10 and so should you 😉
Practice the multiplication of 10 with our Galileo Galilei, a favorite member of the MegaGeex.
