Day 1 -False knowledge

Rene Descartes a famous philosopher and mathematician once said that to find an absolute truth all the previous knowledges must be placed in doubt so ... I felt kind of weird once I found out that one of the main believes we are taught at school was false and it is as follows:  

Sir Isaac Newton did not discover the theory of gravity after an apple fell in his head. Don't get all alarmed thinking that I'm contradicting history. It's just like that game "broken phone" the story has been taught so many times that it could've got a little twisted. But it is true that Sir Isaac Newton discovered the theory of gravity. What is false is how he discovered it. 

That apple did not fell on his head, Newton just wondered about the behavior of the apple and so he asked himself "Why should that apple always descend perpendicularly to the ground, thought he to himself; occasion'd by the fall of an apple, as he sat in contemplative mood. Why sh[oul]d it not go sideways, or upwards? But constantly to the Earth's centre? Assuredly the reason is, that the Earth draws it. There must be a drawing power in matter" So there you have it. 
Physics teachers, please next time you tell the story, don't tell it as a Disney Fairy tale, thanks. 

Thats it. 

Love, Chips.
