Geologic Column: Get busy living!

Whether imprisioned literally or figuratively, one has a choice: Get busy living or get busy dying. A recent stint with temporary invalidity got the author thinking about how he has rekindled the creative fires and enthusiasm at various times throughout his life and career, and his keys to getting busy living again.

Geologic Column: Geography as destiny: How glaciation led to the Civil War

It intrigues me how geography — a product of dynamic processes shaping Earth’s surface — influences our lives, culture and even plays a hand in the affairs of nations. Take, for example, the last glacial maximum, which shaped parts of North America roughly 20,000 years ago, and in doing so contributed to factors that eventually led to the American Civil War.

Geologic Column: Combining art and geology in the sand

Once upon a time, sand sculptures made of sand were mostly castles, built by children and families on a summer vacation to the beach. Today, sand sculpting is also a serious business. But it all starts with the sand — which starts with geology.

Geologic Column: How T. rex got its street cred back

Apparently, T. rex was in danger of losing its street cred as the scariest meat-eating hunter of all time. Until a recent discovery, the lumbering giant was being dissed as a sneaky scavenger. Forensic paleontologists to the rescue!

Geologic Column: By train or pipeline: That is the question

Transporting hazardous materials like oil on North America’s aging rail networks is risky. But pipelines are also risky. So what’s the best option, given that we must choose one?

Geologic Column: Beyond geology, field camps teach teamwork and inspire leadership

For undergraduate geology students, field camp is a rite of passage. And the importance of the experience, in terms of properly training and preparing geoscience students to become geoscience professionals, should not be underestimated.

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.

Geologic Column: Data security: freezers, floppies and flash drives

In the olden days, many of us protected our field notes, lab records and draft manuscripts by making multiple photocopies, storing them in different places, and perhaps keeping one in the freezer in case of fire. Today, much of our data is collected and stored electronically. What strategies do we use now to protect against catastropic loss?

Geologic Column: Beer's secret ingredient: geology

Geologists have a long history with beer. Earlier this year, I decided to raise my own beer appreciation to the next level and take a class on the subject. I attended the beer school at the Anheuser-Busch Brewery in St. Louis. A few minutes into the class, our instructor noted that the beer-brewing process uses clean water, which, he said, is basically the same no matter where you are. Unfortunately, that got us off on the wrong foot.

Geologic Column: Assessing energy and mining workforce needs

In his 1971 book, “Encounters with the Archdruid,” John McPhee quoted Charles Park, an economic geologist who worked at the U.S. Geological Survey and then Stanford University, who said, “People seldom stop to think that all these things — planes in the air, cars on the road, Sierra Club cups — once, somewhere, were rock. Our whole economy — our way of doing things, most of what we have, even our culture — rests on these things.” Although McPhee’s emphasis was on the balance between environmental protection and our societal need for raw materials, the book highlighted the fundamental importance of energy exploration and mining, an idea that implies still another significant message: Our society needs scientists, engineers and skilled laborers who can locate and extract raw materials and energy sources from the rocks beneath our feet in order to power our economy and our way of life.
