# TGA reaches new milestone

I don’t know why, but our species loves whole numbers. Especially big ones. With this strange human appreciation for whole numbers I happily report TGA has officially cracked **2000 posts**!

On a side note, did you know there are more irrational numbers than rational ones, even though there are an infinite amount of both? This little known fact has sent multiple mathematicians to the insane asylum. Seems as though the Universe is prone to irrationality, mathematically speaking of course. I wonder if that’s also true for human nature…

Huzzah for TGA!

Speaking of numbers, I have a great book called ‘As Easy as Pi’ by Jamie Buchan that’s just filled with stuff about numbers, though nothing to do with maths.

## Andy Scott

Bah, meant to say ‘not just to do with maths’.

2000 posts, cool. I’ve been listening since Episode 7, and i check out the site very occassionally (like once or twice a year), but i plan on becoming a it more active.

Great time for a milestone. Here’s another one for you. Mubarak stepped down! Hit up http://www.youtube.com/user/AlJazeeraEnglish to watch it live. Great fucking news for democracy.

“On a side note, did you know there are more irrational numbers than there are rational ones, even though there are an infinite amount of both?”

Makes sense. Hear me out.

There’s (-inf…inf) real numbers, in the form of (a), while there’s (-inf…inf)*(-inf…inf) irrational numbers, in the form of (a+bi).

“There’s (-inf…inf) real numbers, in the form of (a), while there’s (-inf…inf)*(-inf…inf) irrational numbers, in the form of (a+bi).”

First of all, what you are describing are complex numbers. Secondly, the cardinality of the set of complex numbers is the same as that of the real numbers. That is, there are just as many real numbers as complex numbers.

Rational numbers are all of the real numbers that can be written as fractions (i.e. one integer divided by another). Irrational numbers are all of the real numbers that cannot be written as such a fraction (such as pi, or square root of 2)
