- Where do numbers come from?
- Have people always used the same sorts of numbers?
- How can numbers be represented?
- What kinds of numbers are there?
- Why do we need root 2, pi and i?
- What’s the difference between XIV and 14?
- What’s the difference between and 421, 4120 or 4021?
In this conference, we will look at the history of numbers and how they are represented. We will find out why we need the types of numbers we have, and whether there are other kinds of numbers that we might need. We will see why we have zero and infinity, and find out about irrational and imaginary numbers. Finally we will ask ourselves if this is the end of our number system or if there will be further evolution in our number system.
