The Hedgehogs of Königsberg

These spikey animals seem exceedingly cheery,
As they run distances that would make you weary,
But they would think it would be nice,
Not to cross a bridge twice,
But they have not yet studied much graph theory.
~
The Hedgehogs of Königsberg.
The Hedgehogs of Königsberg for fun try to run over each bridge once and once only while they are out jogging.

Mathematical Ignorance

Whilst not wishing to dismiss lower forms of knowledge (only joking) I have decided that along with my main war against elephant leg (doner) kebabs that mathematical ignorance needs to be seen as a dangerous state to be in. Some people seem almost proud that they are making themselves open to be manipulated by charlatans and con-men (or both in the case of politicians)…

Art and literature is trendy and cool,
And its hip to be a mathematical fool,
But if you’re the one,
Fooled by the next con,
You will then feel a bit of a tool.
~

Incidently a lot of mathematically competent people are ignorant about how maths has shaped our culture. This makes maths ignorant people doubly ignorant. To address this I have started posting scenes from mathematical history.
