the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
