how did james bradley calculate the speed of light. He is best known for two fundamental discoveries in astronomy the aberration of light 17251728 and the nutation of the Earths axis 17281748. In his case 301000 kilometers per second.

Romers view that the velocity of light was finite was not fully accepted until measurements of stellar aberration were made in 1727 by James Bradley 16931762. The measurements were getting better. When the light would shine it would pass through the gap between two teeth.
If not instantaneous it is extremely rapid.
When the light would shine it would pass through the gap between two teeth. The Dutch scientist Christiaan Huygens who first did the arithmetic found a value for the speed of light equivalent to 131000 miles per second. The mirror would reflect the beam back and would shine through the next gap between the teeth. These discoveries were called the most brilliant and useful of the century by Jean Baptiste Joseph Delambre historian of.
