A permanent base on Mars would have a number of advantages beyond being a bonanza for planetary science and geology. If, as some evidence suggests, exotic micro-organisms have arisen independently of terrestrial life, studying them could revolutionise biology, medicine and biotechnology.
While I was at community college, I studied industrial design because I thought maybe I'd be an automotive designer - I grew up in Detroit - and I also studied, geology because I was interested in science, a little bit.
Measuring nuclear yield depends on multiple parameters - the location and number of instruments, the geology of the area, the location of the seismic station in relation to the test site.
You won't see me writing about particle physics, or even planetary geology, or chemistry. I practically failed chemistry, and if I had to write a book in any of those areas, I don't think it would go well.
My only wish would be to have 10 more lives to live on this planet. If that were possible, I'd spend one lifetime each in embryology, genetics, physics, astronomy and geology. The other lifetimes would be as a pianist, backwoodsman, tennis player, or writer for the 'National Geographic.'
Too much detail can bog down any story. Enough with the history of gunpowder, the geology of Hawaii, the processes of whaling, and cactus and tumbleweed.
Caves are whimsical things, and geology on a local scale is random and unpredictable.
One of the most important things about the geology on the moon is your descriptions of what you see, comparing them to things that you've seen on Earth so that the geologists and the scientists on the ground would know what you're talking about; and then take pictures of them.
The Secret Doctrine is the common property of the countless millions of men born under various climates, in times with which History refuses to deal, and to which esoteric teachings assign dates incompatible with the theories of Geology and Anthropology.
I'm fascinated by the narrative of geology, and I'm a veritable pack rat of a collector on the road. I keep a rock hammer in my car.
