Do living organisms defy the second law of thermodynamics?
Do living organisms defy the second law of thermodynamics? We can view the entire universe as an isolated system, leading to the conclusion that the entropy of the universe is tending to a maximum. However, all living things maintain a highly ordered, low entropy structure. Which law of thermodynamics states that absolute zero Cannot be […]

Which mineral properties can you identify without special tools?
Which mineral properties can you identify without special tools? In working with hand samples without specialized tools, mineral hardness is specified by the Mohs hardness scale. The Mohs hardness scale is based 10 reference minerals, from talc the softest (Mohs hardness of 1), to diamond the hardest (Mohs hardness of 10). It is a relative, […]
