O knihe

Excerpt from Colorado, Top of the World

Assistant Professor of Geology and Mineralogy, Colorado State School of Mines.

Radium! N ature's Magician! Energy so concentrated that 35/1000ths of an ounce of radium bromide will raise the temper ature of an ounce of water over 6° F. In an hour, yet its power is only half dissipated in l 760 years! So rare that a pound is worth over yet so widely disseminated that it is prob ably the cause of a considerable proportion of the internal heat of the earth! If present in the sun in the proportion of only parts in it accounts for the hitherto inexplicable maintenance of solar radiation, which is a prerequisite for organic existence! Its use in medicine and surgery has only begun, but marvelous results have already been attained, and still more wonderful cures may confidently be expected. No one dare predict the extent of its use as an illuminant when it shall be more cheaply produced. Its prop erties have confounded the illiterate and scientists alike, and, as a result of the investigation of radioactivity, it is now an admitted fact that some elements can transmute or change into others. No one can prophesy what the future holds in this line.
