# Reintroducing Maths For Normal People

Back in spring I started a series on interesting mathematical topics for the layman. Now I’m back with some fresh stuff. I’m still aiming to explain thrilling areas of pure mathematics to a non-mathematical audience.

My first huge topic is infinity. In spring, you may have read these articles:

- My Cardinal Is Bigger Than Yours, on how
*not*to count with your fingers. - Of Macbeth And 100,000 Monkeys, on probability versus monkeys with typewriters.
- Infinity Plus Three, on how much infinite the infinity is.

And we continue with…

- Aleph-Null Bottles Of Beer On The Wall, a quick summary of our weird results.
- All The Numbers In The World, on the infinities of
*un*natural numbers. - The Bigger Infinity, on the frightfully vast infinity of real numbers.
- The Set of Subsets of a Set, on puting sets inside sets and setting subsets of a set to form new sets. Also, monkeys.
- Infinity of Infinities, on where is the end of infinities.
