Page 59 - All these things being considered, it seems probable to me that God in the beginning formed matter in solid, massy, hard, impenetrable, movable particles, of such sizes and figures, and with such other properties and in such proportion to space as most conduced to the end for which he formed them...
Page 108 - For to say nothing of half the birds, and some quadrupeds which are almost entirely supported by them, worms seem to be the great promoters of vegetation, which would proceed but lamely without them, by boring, perforating, and loosening the soil, and rendering it pervious to rains and the fibres of plants, by drawing straws and stalks of leaves and twigs into it ; and, most of all, by throwing up such infinite numbers of lumps of earth called worm-casts, which, being their excrement, is a fine manure...
Page 589 - I often say that when you can measure what you are speaking about and express it in numbers you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind: it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of science, whatever the matter may be.
Page 169 - From calibration of a neutron probe we know that when a soil's volumetric wetness is 1 5% we get a reading of 24,000 cpm (counts per minute), and at a wetness of 40% we get 44,000 cpm. Find the equation of the straight line defining the calibration curve (in the form of Y = mX + b, where Y is counts per minute, X is volumetric wetness, m is the slope of the line, and b is the intercept on the Y axis).
Page 309 - I will never again strike down every living thing as I have done. 22 As long as the earth endures, seedtime and harvest, cold and heat, summer and winter, and day and night will not cease.
Page 277 - ... the thoughts of all men in all ages and lands, they are not original with me, If they are not yours as much as mine they are nothing, or next to nothing, If they are not the riddle and the untying of the riddle they are nothing, If they are not just as close as they are distant they are nothing. This is the grass that grows wherever the land is and the water is, This is the common air that bathes the globe.
Page 243 - Doth a fountain send forth at the same place sweet water and bitter? Can the fig tree, my brethren, bear olive berries ? either a vine, figs ? so can no fountain both yield salt water and fresh.
