2. Let A be an uncountable subset of R.
Prove that there is a subset of distinct elements {a_n : n=1,2,...} of A such that sum of a_n (from n=1 to infinity) diverges.

Topology Questions?

1. (a) show how to write N(natural numbers) as the union of infinitely many infinite pairwise disjoint subsets.
(b) show how to write N(natural numbers) as the union of uncountably many sets with the property that, given any two of them, one is a subset of the other.

2. Let D be a countable set of points in the plane R^2,
Prove there exist sets A and B such that D = A U B,
where the set A has finite intersection with every horizontal line in the plane and B has finite intersection with every vertical line in the plane.

do you believe in this theory?

some scientists think left handed people were actually suppose to be born with a mirror twin. mirror twins are twins that are opposites from each other, one is born left handed and one is born right handed.scientests believe that left handed people were created because their right handed mirror twin caused them to be left handed. unfortunately, the right handed mirror twin died in the womb of the mother at an early stage of developement and dissolved in the fluid in the womb. what was left was the left handed mirror twin. this would explain why only 9% of people on earth are left handed. what are you guys' thoughts on this theory?
