What does " nested intervals" mean in this sentence ?
Set theory was born on that day in December 1873 when Georg Cantor
(1845–1918) established that the continuum is not countable—there is no
one-to-one correspondence between the real numbers and the natural numbers 0, 1, 2,.... Given a (countable) sequence of reals, Cantor defined nested
intervals so that any real in their intersection will not be in the sequence

Nested means one inside another, inside another etc. like Russian dolls.
