In calculus class, you might feel tremendous shivering when you graph the function
with your hand by differentiating. It is obvious that people can graph a function
by graphing calculator. However, you can draw the function by your hand. Graphing it
by hand gives you much pleasure because you did not "high-tech measurement machinery the 21st century." Like that, about 120 years ago, Canada in oceanographer estimated "the total volume of the Earth's sea water". By his estimation the total volume was "1,349 biilion cubic kilometres." It was so close to measuring by Scientist who used the "latest satellite technology, sophiscated computer modelling tolls and global bathymetric" The only difference between estimation and measuring was "only about five times the volume of the Gulf Of Mexico" Seems like Murray, who "left Canada at 17 to study' made a huge footprint in the world of ocean science. He estimated the depth of ocean by only using "records of travellers,
of deep-sea expeditions, and the hydrographic surveys of various nations" By his estimation ocean scientist could measure "more accurate modelling of climate change,ocean circulation and salinity." Put all his achievement beyond, he died in 1914 because of "first car accidents in the British Isles." His life reminds me a famous proverb; " Tigers leave only their skins when they die, but through his achievements a man´s name lives on."
