McCoy, curator of meteorites at the museum, is analyzing other samples of the asteroid in the museum’s Department of Mineral Sciences to classify and describe the textures of the rocks and the kinds of minerals they contain. The sample that has just arrived at...
Together with petrographic thin section observations Earth scientists classify igneous rocks and draw interpretations about: • The petrogenesis and evolution of igneous rocks. • The thermal and barometric conditions in which a primary magma have formed. • The magmatic processes that might be ...
When scientists arrived on the scene to recover and classify the pieces, they discovered something remarkably rare: The rocks belonged to an extremely uncommon group of meteorites known asaubrites, which remain mysterious to researchers.Just 80of the roughly 70,000 recove...
Researchers from Arizona State University and NASA’s Jet Propulsion Laboratory invited the public to help classify data from a number of orbiting Mars instruments, including the NASA Mars Odyssey orbiter’s THEMIS camera and the Mars Reconnaissance orbiter’s CTX and HiRISE instruments. Through theZ...
in which creationists that refuse to accept the evolutionary descent of humans from earlier primates attempt to mask the clearly quantifiable gradient in characteristics between humans and ancestral primates by choosing to classify a hominid fossil as either human or non-human ape (more on this in ...
Along similar lines, Balasubramania & Stevenson (2001) did some interesting work on model fitting. In this work it was assumed that the shadows from targets such as cones, cylinders and rocks were close to an ellipse. Hence the shadow shapes were modelled as ellipses. To this end the ...
and classify all the features of the world, whether characteristic or not, to get hypotheses with which to explain their presence and their development and to plan means of checking opposing ideas for his or her relative validity. In this way, theforemost plausible, acceptable, and long-lasting...
They identified the different cover types on the bioswale (e.g., bare soil, rocks, trees, and trash) and used different shading to classify each grid on their drawing of the swale. These data were used to determine the percentage of each cover type on the swale. The locations of the ...
