This IOT season starts with bang. In the first 3 minutes of Imaginary Numbers our guest professor runs through thousands of years of the develop of number, from positive integer to zero (ok, I think he skipped zero) to fraction to irrational to negative to imaginary to infinity.
As he spoke I realized IOT has done a programme on all of these save fractions. Taken together, it is a wonderful introduction to mathematics and some of the better sides of human history.
Nice way to start the year.
