Science Awakening II: The Birth of Astronomy

Whoever desires to comprehend the genesis of recent technological know-how has to persist with 3 traces of improvement, all beginning in antiquity, that have been introduced jointly within the paintings of ISAAC NEWTON, particularly 1. old arithmetic => DESCARTES 2. historic Astronomy => COPERNICUS: I=> NEWTON three. historical Mechanics => GALILEO => HUYGENS In technology Awakening I (Dutch version 1950, first Eng1ish version 1954, moment 1961, first German version 1956, moment 1965) i've got the 1st 1ine, giving an overview of the improvement of arithmetic in Egypt, Babylonia, and Greece.

304 em. Thus, there is very little difference in the total amounts of ozone for these cases and case I, despite the large differences in temperature above 30 km. 5 km and above, the effect of temperature is obvious, the most ozone being formed for case VIII (winter), the least for case VII (summer). 5 km is too small a percentage of the total amount for this to affect the total amount very much. Below 30 km, the measured temperatures at 45°N in summer and winter are quite similar to each other and to the standard distribution.

Thus the rate of change of 113 is relatively larger the farther 11 3 is from equilibrium. 8). Table 4 gives the time Llt for these changes at levels below 40 km for cases I, II, and V. The results in table 4 show that above the level of maximum ozone at 30 km, the amount of ozone is usually apt to be near equilibrium. At, and especially below the level of maximum ozone, however, the VoL. 2 computed times are so large as to indicate that the ozone is practically never in equilibrium with the sun.

Air moves northward more or less parallel to the tropopause, diverging vertically as the tropopause drops and converging horizontally as the meridians converge. At high latitudes, as the tropopause levels off, the air must penetrate the troposphere or rise and return at high levels (perhaps 30-50 km) to equatorial regions. The ozone leaving equatorial regions is continually replenished by photochemical processes and is fed into lower levels at middle latitudes where it is protected from photochemical destruction.
