Separate settled science from reality

first_imgI read with interest and not a little bit of dismay Mr. John Gaetani’s Oct. 15 letter stating that a flat earth was “settled science” in 1492. In fact, a scholar named Eratosthenes of Cyrene (present day Libya), born 276 BC died 194 BC, knew that the Earth was a sphere and was able to calculate the circumference of the planet to a remarkably accurate degree.Columbus had studied this, but had chosen to believe that the circumference was smaller than calculated and, therefore, didn’t realize that he hadn’t made landfall in Asia. Mr. Gaetani has also confused “settled science” with religious dogma when making the argument that Galileo had “upended the scientific establishment” by proffering a new view of the solar system.In fact, Copernicus, who died in 1543 (Galileo was born in 1564), had already established the hypothesis that the sun was the center of the solar system. Mr. Gaetani’s argument that global climate change isn’t real because he doesn’t agree with the idea is not “settled science.”Debra KenfieldSchenectadyMore from The Daily Gazette:Schenectady, Saratoga casinos say reopening has gone well; revenue down 30%Motorcyclist injured in Thursday afternoon Schenectady crashEDITORIAL: Find a way to get family members into nursing homesEDITORIAL: Thruway tax unfair to working motoristsSchenectady department heads: Budget cutbacks would further stress already-stretched departments Categories: Letters to the Editor, Opinionlast_img
