Mathematical is useful for modern life. There is:

• Game theory – for dating
• Obstruction theory – for when you ask government for something
• Braid theory – for doing your daughter’s hair
• Distribution theory – for trying to manage a budget
• Invariant theory – for dealing with death
• Chaos theory – for raising a family

But don’t despair you Arithmophobes

No knowledge of any of these subjects has actually helped anyone deal with the practical problems of life

Except managing a budget

Which is stubbornly a mathematical thing

In the end
