Which preposition to use with radiation
The surface was pitted with oval hollows, made by stones and drifted pine-needles that had melted themselves into the mass by the radiation of absorbed sun-heat.
Mr Stone's results for the radiation from Arcturus and alpha Lyrae appear to be incontrovertible, and to give bases for distinct numerical estimation of the radiant heat of these stars.
For the same surface which has had fourteen days of sunshine has also had a preceding fourteen days of darkness, during which the heat which it had accumulated in its surface layers would have been lost by free radiation into stellar space.
I have sent to the Philosophical Magazine a paper in which I think it is shown that when the radiation by the atmosphere is taken into account the results are entirely changed.
This rapid fall while exposed to oblique sunshine is quite in harmony with the rapid loss of heat during the few hours of darkness during an eclipse, both showing the prepotency of radiation over insolation on the moon.
The first floor is laid, but over this there will be a quilting, a felt layer, a second boarding, and finally linoleum; as the plenteous volcanic sand can be piled well up on every side it is impossible to imagine that draughts can penetrate into the hut from beneath, and it is equally impossible to imagine great loss of heat by contact or radiation in that direction.
Heating is accomplished by indirect radiation with the steam supply from the power house, but there are many open fireplaces to add to the complete stack and flue system of ventilation.
Accordingly, an observation of the temperature produced by solar radiation at a zenith distance whose secant is twice that of the secant of 17° 12', viz., 61° 28', determines the minimum atmospheric absorption at New York.
PAGE SUMMARY AND CONCLUSION, The canals the origin of Mr. Lowell's theory Best explained as natural features Evaporation difficulty not met by Mr. Lowell How did Martians live without the canals Radiation due to scanty atmosphere not taken account of Three independent proofs of low temperature and uninhabitability of Mars Conclusion.
Rapid Loss of Heat by Radiation on the Earth.
Using these datawith Stefan's law of decrease of radiation as the 4th power of the temperaturea mathematical friend finds that the temperature of the moon's surface would be reduced during the lunar night to nearly 200° F. absolute (equal to-258° F.).
