...real estate. An 18-hole standard course takes 125-175 acres, but 18-hole par-three takes only 40 because of its smaller tees and greens and shortened fairways. This also enables compact courses to be built much closer to cities; some 200 of them are equipped with mercury-vapor lamps and are thronged far into the night...
...response to tiny fluctuations in temperature. Special filters allow only a very narrow band of the infrared, between eight and 14 microns, to fall on the thermistor. The filter rejects the shorter infrared waves omitted by the sun and reflected by the moon. The earth's atmosphere, where water vapor, ozone and carbon dioxide absorb other portions of the infrared, also acts as a sort of filter. However, one can easily derive the temperature of the moon from the intensity of infrared radiation in the band transmitted between eight and 14 microns...
...planet. Mars has no light of its own. The light that it sends to the earth is sunlight that passes down through the thin Martian atmosphere and is reflected out again. Loss of certain infra-red wave lengths during these two passages will prove the presence of water vapor, carbon dioxide and other interesting, life-supporting constituents...
First quick studies of Stratoscope's data showed that water vapor and CO2 are indeed present, but scarce. Now the data have gone to the University of California for closer analysis, as scientists continue their search for any evidence of the possibility of Martian life...
...fine dust, kicked up from the surface by tremendous winds in the dense atmosphere, but Professor Kaplan has a more picturesque theory. He thinks they are hydrocarbon droplets similar to the water droplets in earthly clouds. The droplets condense in the cool top of the atmosphere, but stay in vapor form in the lower parts, where the temperature rises above 200° F. So the dark Venusian surface has clear, compressed, oily air. Infra-red rays from the sun penetrate both clouds and atmosphere, but are hindered by the CO2 when they try to escape. This trapped energy keeps...
