Hi, All:(adsbygoogle = window.adsbygoogle || []).push({});

I was thinking of the result that every compact metric space is the continuous image

of the Cantor set/space C. This result is built on some results like the fact that 2nd

countable metric spaces can be embedded in I^n (I is --I am?-- the unit interval),

the fact that there is a continuous map between C and I, and, from what I read

recently , the fact that every closed subset of C is a retract of C.

How do we know that every closed subset of C is a retract of C?
