Document Summary

Willow bark(aspirin) reduces imflamation(reductionism: mutation of dna molecules. Look at all the interacting parts, to understand its complexity, we aren"t advanced enough to understand the earth. To understand everything you need to look bottom up and up bottom to understand the whole thing. The earth has changed: evolve there is a beging and an end and things will change. Ex)positive =volcanism-co2-raise temp-more water vapour in the atmosphere-greater green house effect-increased temp. Negative feedback loop= increased green house effect-higher weathering(rock disintegrates, adds ions to the oceans)-decreases co2 through caco3 ppt-decreased temp- etc. Geologists solve the crimes that the earth commits. Physical laws of nature have not changed (the modern is the key to the ancient: climate change, evolution etc. Ex) carbon ashes =cremation diamonds (essentially this is a controlled experiment because you control the input and the output): where might they come from, bolite impacts, mining, atoms, minerals, microfossils, earth, solar system and beyond.
