For the last several months, I’ve been working on a website called Mathematics Monster. I hope that one day it will be the go-to website for people wanting to find out about any mathematical subject.
Today, I have been writing about Pythagoras’ theorem:
In a right angled triangle:
the square of the hypotenuse is equal to
the sum of the squares of the other two sides
More visually, if you have a right angled triangle (where one angle is 90°), and draw squares onto each of the sides…
…then the area of the red square is equal to the area of the blue square added to the area of the yellow square.
This is useful for those wanting to pass Maths exams*, but a little dry.
So I added a little bit of movie trivia…
In The Wizard Of Oz**, Scarecrow joins Dorothy and the gang’s quest to find the Wizard, hoping to get a brain:
I hope it’s no great spoiler to tell you that Dorothy & Co. finally reach the Wizard, and after melting the Wicked Witch of West are duly rewarded with a ride back to Kansas, a brain, a heart, and ‘the noive’***. But, once Scarecrow is given a brain and handed a Diploma, the straw-headed nincompoop only goes and commits one of the most egregious mathematical howlers ever committed to celluloid.
..which is neither Pythogoras’ theorem nor correct.
That Wizard of Oz, eh?! You’d think he’s some charlatan hiding behind a curtain, pulling on levers…
* Possibly the greatest comedic answer to a Maths question involves Pythagoras’ theorem:
*** ‘the nerve’, or courage, in a broad Brooklyn accent.
