When oil and water mix

Hydraulic fracturing of organic-rich shales has become a major industry. The commonly used term for this extraction of hydrocarbons—fracking—is especially intriguing. Not only does it convey the process of breaking apart rocks, but the dividing of public opinion. Fracking is simultaneously hyped as a boon to the economy and a disaster to the environment.

The Erdos conjecture for primitive sets

A subset of the integers larger than 1 is $primitive$ if no member divides another.

In 1988 he asked if this universal bound is attained for the set of prime numbers. In this paper we make some progress on several fronts, and show a connection to certain prim
