## Still Fighting After All These Years

Infinity has always been controversial for mathematicians. Scientific American has a great article on the continuing debate. These questions and dilemmas have a special place in my heart. It was the first part of mathematics I’d seen that was as interesting as philosophy, my first love. It is a good read. I hope you enjoy.

## Show Me the Money?

I caught a great Planet Money podcast about the relative earning potential of different degrees. Engineering and applied math careers are always at the top of the these lists, but thanks to data from the last census, we are able to see just what the difference is. The graph above is a thumbnail sketch. I recommend listening to the podcast. The Planet Money team always does a fantastic job.

## Curious Units

Units have been going through my mind a lot lately. I ran into this on Futility Closet. It made me speculate what a Hendree unit might be? Doesn’t everyone deserve a unit named after them? Any suggestions?
