Page 101 - ... bodies into the space around them. Such radiation may (like ordinary white light, which is radiation from the sun) be analysed into a continuous spectrum of waves, differing in frequency. In general, the absolute amount of energy radiated, and its distribution among the various frequencies, depend not only on the temperature of the hot body but also on its intrinsic physical properties : if, however, the body has the property that it absorbs all the radiation that falls on it, without scattering,...
Page 326 - After explaining Thieme's conception of chip removal, which is a pressure process, he adds, "There comes into question not only the resistance to penetration, but also the resistance to the pressing aside of the chip element," and concludes with, "we arrive thus at the law that machinability depends on both hardness (eg, ball hardness )and workability, the difficulty of machining increasing with an increase in either property.

Page vi - Mineralogie usw. binuberstreckt." (In the 587043 investigations of recent decades, the study of metals and alloys has been lifted out of the realm of pure empiricism, to which it had previously been confined, and developed into a distinct science whose roots extend into many different related sciences — chemistry, physics, mechanics...

Just as spectacles are of no use to the blind, so structural appearance means nothing to those who have failed to secure comprehensive knowledge in the fields of material research and technology...
