Down to Earth With: Geologist Robert Brinkmann

As a child, Robert Brinkmann was always curious about rocks. He wondered how they got where they were and why they were different from each other. Brinkmann grew up in the farm country of southeastern Wisconsin, as well as in the woods in the northern part of the state. After one of his first geology classes in college, he went home and finally understood what he was looking at. “It was such an eye-opening experience to be able to read the landscape,” Brinkmann says.

Geologic Column: Riding the rails to Omaha with Rudolf Clausius

It was the German physicist Rudolf Clausius who, in 1850, dressed the Second Law in a tuxedo to show us that the pigpen was infinite. He said, “the entropy of the universe strives to reach a maximum.” That is a beautifully concise vision of our fate with the clear message that in the grand scheme of things, there is no escape. We’re all doomed and can do nothing about it. All order in the universe will degenerate into chaos.

Down to Earth With: Evan Thomas

At age 16, Evan Thomas made a list of 100 life goals — his bucket list. At only 27 years old, he’s done pretty well so far: Graduate college with a degree in aerospace engineering — check. Get a doctorate by age 25 — almost (missed by 11 days). Work for NASA — check. Start a business, help people, travel the world — check, check, check. Get a private pilot license — check. Climb the world’s tallest mountains — in process.
