scintillations

He rarely worked this hard, and the scintillations he had seen around the metal slug had to be the retinal flares of oxygen hunger.

The sands for yards around swam with photonics, scintillations, reflection and refraction.

They articulate the evolution of English music from simple canonic rounds to the gorgeous chromaticism of Herbert Howells and scintillations of Benjamin Britten and Michael Tippett.

As they argued, there was a considerable difference between the results obtained by Karlik's and their experiments concerning the question of how the amount of light, entering the eye from an individual scintillation, affects the number of total scintillations observed.

It had a numerical aperture of 0.70 and the field of view was decreased from 12.5 mm2 to 8 mm2. 54 "It may be added," Dagmar argued, "that the use of a greatly improved microscope made it relatively easy to distinguish between scintillations from H and from alpha particles, so that they could be counted separately."

That gave her the opportunity to observe the slow, weak scintillations from H-particles.

Additionally, weak scintillations were not always observable.

For instance, in her later experiments, Kara-Michailova had employed two groups of observers who simultaneously recorded the scintillations produced by alpha and H-particles. 171 In all cases, these observers were characterized as "highly specialized."

As her diary indicates, she was involved in designing apparatus for the groups experiments and her own, counting scintillations, extracting polonium from residues from Joachimsthal radium ores, and critiquing Hans's manuscript.

Thus it may be that what is to be counted is the total number of scintillations made on the screen in two minutes and at the end of it he will write down the number told him by the observer.
