A very good summary, easily understood. I would be quite interested in a look at the difference between natural numbers and ordinal numbers at some point in the future as the difference is not obvious.

The ordinal numbers include the natural numbers, but include infinite quantities as well. The first ordinal number that is larger than all natural numbers, that is, the first infinite ordinal, is called ω. Then, you have ω + 1, ω + 2, and so on.

très bonne vidéo ;)

thanks

Might be interesting to do a video on the subsets of the algebraic numbers showing how some of them can’t be written down in closed form. Which of course is related to Galois’ discovery that there are no closed formulas for the general solutions of polynomials of degree 5 or greater.

Good idea, John - I'll add it to list for early 2020.
