The light obtained by setting straw men on fire is not what we mean by illumination.
In 1849 Fizeau found the first reasonably accurate value of the velocity of light obtained in a nonastronomical experiment.
Heckscher told The Real Estate Record & Guide that "it will be a boon to New York if owners of high buildings will build in such a manner that each high building shall be wholly self-contained, light obtained from the outside on each facade".
Figure 2 shows microscopic images (under the reflected light) obtained on the blue and green paint layers.
b A schematic diagram shows the formation of closed-loop path of light obtained from recurrent light scattering under different excitation intensity.
The colour-rendering index of the white light obtained from the nanotubes was 87, while the nanorods-based LED emit yellowish colour.
Photographic evidence of the earthquake light obtained during earthquake swarm activities in Matsushiro, Japan, in 1960s, caught the attention of geophysicists (Yasui, 1968, 1971; Derr, 1986).
Experiments of spectral quality were performed in the same light-tight room, under red or blue light obtained through a filter sheet (Plexiglass GS Rot 501 or GS Blau 610, 3 mm thick; Rohm GmbH, http://www.rohm.com).
Figure 4, for instance, shows the spatial variation in the DOP, DOLP, DOCP and anisotropy, r, as was derived from SHG light obtained from starch granules upon illumination with different polarization states.
Fura-2 AM fluorescence was elicited by alternate (every 2 ms) illumination with 340 and 380 nm light obtained using a monochromator (Optoscan Fluorescence System, Cairn Research, Kent, UK) in front of a Xenon excitation lamp.
