Geologic Column: What geoscientists can learn from TED Talks

TED talks have become an international — and Internet — phenomenon. The presentations are pithy, conversational, focused and entertaining; they are often inspirational and sometimes very personal. Geoscientists — whether presenting conference papers, classroom lectures or presentations for general audiences — can learn a lot from TED talks, especially from the structure and guidance applied to preparing the talks.

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: 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: 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.

Geologic Column: Sometimes, the sky really is falling

Airplane pilots have a long history of using euphemisms to minimize the sense of risk in their work. Pilot-speak for crashing an airplane, for example, is “ruining your entire day.” In the same parlance, encountering an asteroid could cause all of us to have a very, very bad day. But maybe our close calls — such as the fireball that flew over Russia in February — can serve as reminders to renew our focus on searching for and understanding objects that could, literally, impact our planet.

Geologic Column: You gotta have a plan

Early in the 1990 film “Tremors,” the character Earl criticizes his colleague, played by Kevin Bacon, for not having a plan. “Valentine, you never plan ahead. You never take the long view. I mean, here it is Monday, and I’m already thinking of Wednesday,” Earl says. “It is Monday, right?”
 
Of course, “Tremors” has a lot going for it: funny dialog, great scenery, monster subterranean worms, a female seismologist, and, of course, Kevin Bacon. But the messages about planning ahead whenever possible and improvising when necessary are ones that every earth scientist will appreciate.

Geologic Column: Lessons from the final frontier

Somewhere, out there, beyond the stars Arcturus and Pollux, the TV signals from the final season of the original “Star Trek” are radiating outward. The series has been a teaching tool for a generation, and the programs offer multiple lessons for earth scientists.

Geologic Column: The double-edged sword of commercialization

Everyone has a mental image of a “commercialized” geologic site — Niagara Falls, anyone? My vision includes crowds, noise, clutter, distracting visual stimuli, neon signs, traffic, and a price on everything from scenic views to water. Souvenirs, including T-shirts, snow globes, shot glasses and fudge, are usually for sale.
