Document Summary
All the rivers run into the sea; yet the sea is not full; unto the place from whence the rivers come, thither they return again. n ecclesiastes 1:7, old testament. Can trace development of ideas from greeks to romans to arab world. Can also find parallel developments in other cultures but the age of reason brought quantitative investigations. Tried to explain grand phenomenon of the equilibrium of the sea. Experiment with evaporation from a pan during summer in. Assumed 12 hours of evaporation and based on area of. Mediterranean sea, each summer day expect 5. 28 x 109 tons of water to evaporate. Estimated inflow from the 9 largest rivers (nile, tiber, po, Danube, etc) by assuming each had flow of 10x that of the. Result was that evaporation was 3x inflow therefore, enough water evaporated to supply all the streams and rivers (saltiness?)
