## 1. The Popeye Myth

July 9, 2013

The Popeye Myth is that spinach contains lots of iron.

According to Brainpickings website

Back in 1870, Erich Von Wolf , a German chemist, examined the amount of iron within spinach, among many other green vegetables. In recording his findings, he accidentally misplaced a decimal point when transcribing data from his notebook, changing the iron content in spinach from 3.5 milligrams of iron in a 100-gram serving of spinach, to 35 milligrams.  It was corrected in 1937, but too late the myth was well established.

This study inspired the Popeye Cartoon character who gets  colossal strength eating cans of spinach.

Unfortunately, it was just a maths blooper. The good news is that:

# Popeye Myth Busted.

Spinach does not have that much more iron than other vegetables.

In 18 months Somebody that I used ot know has scored 375 million hits. How many hits per minute?

(Ans: Assuming 30 days per month the no of hits per minute is 482)

## Fun with Geometry Exercise:

Here’s Somebody that I used to know. Put on the music and do geometry especially triangles.

It’ll either help students do their exercises or work like Clockwork Orange and have them running screaming out of the room when they hear the first few notes.
