Mineral Resource of the Month: Diamond

Diamond is an extremely stable form of carbon: It is a material with superior physical properties due to the very strong covalent bonding between the carbon atoms. Diamond has the highest hardness and thermal conductivity of any known natural or synthesized material. In diamond, the carbon atoms are arranged in a rigid cubic crystal structure called a diamond lattice — it is this lattice that blocks impurities, thus giving diamond its colorless appearance.

Down to Earth With: Buzz Aldrin

On July 20, 1969, Apollo 11 astronauts Buzz Aldrin and Neil Armstrong made history when they landed and walked on the moon. The voyage left a lasting impression on Aldrin, who, at the age of 79, is one of the most vocal supporters of human space exploration.

Benchmarks: November 22, 1859: "On the Origin of Species" published

By David B. Williams

About a decade ago, I was fortunate enough to hold in my hands a first edition of Charles Darwin’s “On the Origin of Species.” The green cover was cracked and frayed. The cardboard backing protruded through the torn corners. I put the book down and stared at it in awe. The owner of this book was Asa Gray, one of America’s greatest botanists, an important early American supporter of natural selection, and a friend of Darwin’s.

Down to Earth With: Lucy McFadden

Not many people can say they have an asteroid named after them. But Lucy McFadden, a self-described small planetary objects junkie, can. For nearly 40 years, McFadden has woven her two loves — astronomy and geology — into a career in planetary geology. She has mapped craters on Mercury, participated on NASA missions to comets, and collected meteorites in Antarctica, all in the interest of discovering more about the formation of our solar system.

Mineral Resource of the Month: Zinc

Zinc is the fourth most-widely consumed metal, following iron, aluminum and copper. The Romans were the first to use zinc. To produce brass, they smelted copper with calamine (a zinc ore) to make an alloy more golden in color than bronze (a copper-tin alloy), which they called calamine brass. They were unaware zinc was involved.

Down to Earth With: Jessica Whiteside

From Morocco to Connecticut, Jessica Whiteside has explored almost every Mesozoic rock outcrop there is. And she’s only three years out of graduate school. With a bachelor’s degree from Mount Holyoke College in South Hadley, Mass., and two master’s degrees and a doctorate from Columbia University in New York, N.Y., under her belt, Whitehouse is now in Providence, R.I., working as an assistant professor of geological sciences at Brown University.
