John Carlin Reviews
I graduated in the U.S. Merchant Marine Academy, also have an MBA from the University of Minnesota. I Reside in Apple Valley Minnesota. As a Merchant Mariner I traveled all over the world and loved the experience of seeing new places.
I am a big "gadgets man" and constantly need to play with some other new gadget, concept, or idea, that comes along. Mental math is a bit of a nerd/wonky thing but it's so many practical applications. My real interest is at the thoughts behind the math, not the mechanical procedure for doing exactly what a calculator could do.
