The movement of the emitters of the spectral lines may be deduced on the basis of the Doppler principle.

Although Einstein enjoyed almost universal acclaim in his day, history has exalted his genius still further by forgetting those few detractors who did exist. . . . Herbert Ives, a physicist for Bell Laboratories, remained unshakeably opposed to relativity, though the Ives-Stillwell experiment which bears his name is generally interpreted as a direct corroboration of Einstein's theory 'His Ives' work on the so-called tranverse Doppler effect, performed with Stillwell in the period 1938-41, is one of three crucial optical experiments which, taken together, lead inductively to the Lorentz transformations as used in the special theory of relativity in a sense it, more than either of the two, may be considered as the cornerstone of the special principle of relativity, as formulated years before by Einstein. . . .' (Howard P. Robertson, professor of physics at the California Institute of Technology, 1956) 'The 'principle' of the constancy of the velocity of light is not merely 'ununderstandable', it is not supported by 'objective matters of fact' it is untenable, and, as we shall see, unnecessary. . . . Also of philosophical import is that with the abandonment of the 'principle' of the constancy of the velocity of light, the geometries which have been based on it, with their fusion of space and time, must be denied their claim to be a true description of the physical world.'
Sometimes a storm on Doppler radar will be so obvious that it's severe that you pull the trigger on it and issue a severe weather or tornado warning. But there will be some days where you look at a storm and it's kind of ambiguous. It may be severe, or it may not.
We'll be looking at what weather information they had been given and then very carefully at the Doppler radar tapes and things of that nature from the area. We'll be looking at what the weather actually was and what the crew thought it was.
I never like calling a game before the scheduled game time, but this was about as heavy a rain as I've seen here. We checked with the weatherman and Doppler radar and we would have needed 3 or 4 hours of sunlight for the field to be ready.
It was created as a way for the average citizen to report what they saw in their neck of the woods during a potentially severe weather situation. Because, despite the fact that we have this million dollar Doppler radar and all this technology at our fingertips, it still comes down to basically eyes on the sky.
We're going to look at how was the data transferred. How did it originally get into system in English units How was it transferred When we were doing navigation and Doppler (distance and speed) checks, how come we didn't find it
However, cases came to light later in which canal rays containing only positive ions showed a Doppler effect in the spectral lines emitted by them.
