Exploring the World of Numbers

The video explores various categories of numbers, starting with whole and rational numbers, and moving through constructable, algebraic, and transcendental numbers. It discusses the concept of computable and uncomputable numbers, highlighting Alan Turing's contributions. The video also covers normal numbers, using Champernowne's constant as an example. It concludes with a promotion of Matt Parker's book, 'Humble Pi'.

• Pie chart

What is the relationship between whole numbers and rational numbers?

• They are completely separate sets.

• They are identical sets.

• Whole numbers are a subset of rational numbers.
