" His true position is in the diagonal of the parallelogram, whose sides are in the ratio of the velocity of light to the velocity of the earth in its orbit, which is as 190000 to 19. "

John Bigelow - 1996 - 72 pages
...is intuitionally the speed of light or tempic field intensity. C>C. is the fine structure constant; the ratio of the velocity of light to the velocity of the electron in the first orbit of the Bohr hydrogen atom. Circular to linear ratio implies orthogonality....

...meeting the circle in P. Thus OP is the distance that light travels in a second. The ratio of OP to OM is the ratio of the velocity of light to the velocity of the body. The ratio of OP to MP is the ratio in which apparent lengths are altered by the motion. That...

...very small one) of the velocity of light. This effect, now known as the 'aberration of light', allowed the ratio of the velocity of light to the velocity of the earth in its orbit to be determined and, knowing the size of the earth's orbit around the sun, it enabled the velocity...

...as would be expected from parallax. He deduced that the movement (aberration) he saw was related to the ratio of the velocity of light to the velocity of the Earth about the Sun. This discovery allowed him to estimate the speed of light to be 3,08,300 km/sec. (Compared...

Sir William Cecil Dampier Dampier - 1924 - 302 pages
...that the star appears to move periodically in space as the year revolves. From this apparent movement, the ratio of the velocity of light to the velocity of the earth in its orbit may obviously be calculated. The first determination of the velocity of light over short distances...
