Page 69 - First, that this intolerable Thing of which the masters of Germany have shown us the ugly face, this menace of combined intrigue and force, which we now see so clearly as the German power, a Thing without conscience or honor or capacity for covenanted peace...
Page 188 - ... or to any body moving with a velocity different from our own, the timedimension also has rotated. What is time to them is partly time and partly imaginary space to us. It is a change in the space-time world of four dimensions just analogous to the change in the space-world between here and Ireland. That is Minkowski's great result ; spacetime is the same universally, but the orientation — the resolution into space and time separately — depends on the motion of the individual experiencing...

In his farewell address to his expeditionary army at Berlin, on the day on which they started for Peking, the Kaiser, as reported in the " Illustrirte Zeitung " of August 2, 1900, said: " You know well you will fight against a treacherous, brave, well-equipped, cruel enemy. When you shall meet him, remember, quarter is not to be given, prisoners must not be made, use your weapons so that for a thousand years to come no Chinaman will dare...
Page 397 - Nebulae; but then they must consist of stars that are compressed and accumulated in the highest degree. If it were not perhaps too hazardous to pursue a former surmise of a renewal in what I figuratively called the laboratories of the universe, the stars forming these extraordinary nebulae, by some decay or waste of nature, being no longer fit for their former purposes, and having their projectile forces if any such they had. retarded in each other's atmosphere, may rush at last together, and either...
Page 444 - But the data being insufficient, we cannot feel sure that the alteration in the dimensions of the orbits of these satellites has not been considerable. It remains, however, nearly certain that they cannot have first originated almost in contact with the present surfaces of the planets, in the same way as, in previous papers, has been shown to be probable with regard to the Moon and the Earth.

Nature states that the council of the South African Association for the Advancement of Science has resolved to institute a Sir David Gill memorial fund, to accumulate for a number of years until an amount has been raised adequate for some purpose to be decided upon.

Page 398 - Anwers has recently found the very considerable eccentric! ty of 0-63 for Sirius. The great relative velocity of the component stars of the Nova, however, seems to point rather to the casual near approach of bodies possessing previously considerable motion ; unless we are willing to concede to them a mass very great as compared with that of the Sun.
Page 187 - ... meaning of science, especially biological science, are feeling after new rules of conduct. The old criteria based on ignorance have little worth. "Rights," whether of persons or of nations, may be abstractions well-founded in law or philosophy, but the modern world sooner or later will annul them. The general ignorance of science has lasted so long that we have virtually two codes of right and duty, that founded on natural truth and that emanating from tradition, which almost alone finds public...
