Ordinals vs Cardinals (and how many algebraic numbers are there?)

If you want to see the transfinite ordinals, then check out the Vsauce video "How To Count Past Infinity".    • How To Count Past Infinity   Here is Simon Pampena's Numberphile video about algebraic and transcendental numbers.    • Transcendental Numbers - Numberphile   My personal favourite way to order and count the rationals.    • Infinite Fractions - Numberphile   Watch James Grime show that the reals are uncountably infinite.    • Infinity is bigger than you think - Number...   Here's what Mathsworld has to say: http://mathworld.wolfram.com/OrdinalN... http://mathworld.wolfram.com/Cardinal... Here is a good English translation of Cantor's 1874 paper "On a Property of the Class of all Real Algebraic Numbers". https://srjcstaff.santarosa.edu/~joma... CORRECTIONS The polynomial which first appears at 3:40 has "n+1" which should be "n-1". Not all complex numbers are algebraic: only some of them are. I phrased this in an ambiguous way.
