The “Law of Truly Large Numbers” is summarized nicely in the following limerick.  I am not sure whether Eddington or Pound should receive credit.

 

There once was a breathy baboon

Who always breathed down a bassoon,

For he said, "It appears

That in billions of years

I shall certainly hit on a tune."

       Sir Arthur Eddington (1882 –1944)

 

There once was a brainy baboon

Who always breathed down a bassoon

For he said, "It appears

That in billions of years

I shall certainly hit on a tune."

       Ezra Pound (1885 –1972)

 

 


That  2À0 = À1   is the continuum hypothesis, where À0 is aleph null and À1 is aleph one.

Kurt Gödel proved that assuming the continuum hypothesis true does not contradict Zermelo-Fraenkel set theory.  Paul Cohen proved that assuming the continuum hypothesis false does not contradict Zermelo-Fraenkel set theory.  Therefore, the validity of the continuum hypothesis is undecidable within Zermelo-Fraenkel set theory.

 

The online essay “You Can’t Get There From Here” on infinity at Platonic Realms (another site I highly recommend) is nicely done and definitely worth a look!
