Sida 181 - God called up from dreams a man into the vestibule of heaven, saying, ' Come thou hither, and see the glory of my house.' And to the servants that stood around his throne he said, 'Take him, and undress him from his robes of flesh : cleanse his vision, and put a new breath into his nostrils : arm him with sail-broad wings for flight. Only touch not with any change his human heart — the heart that weeps and trembles.
Sida 80 - GRAVITATION.* — Every particle of matter in the universe attracts every other particle of matter with a force directly proportional to its mass, and decreasing as the square of the distance Fig.
Sida 60 - If you forgive me, I rejoice; if you are angry I can bear it. The die is cast. The book is written, to be read either now, or by posterity, I care not which. It may well wait a century for a reader, since God has waited six thousand years for an observer!
Sida 143 - ... we calculated from morning till night, sometimes even at meals ; the consequence of which was, that I contracted an illness which changed my constitution for the remainder of my life. The assistance rendered by Madame Lepaute was such, that without her we never...
Sida 248 - The proposition that the sun is in the centre of the world and immovable from its place is absurd, philosophically false, and formally heretical ; because it is expressly contrary to the Holy Scriptures.
Sida 242 - how I wish that we could have one hearty laugh together. Here, at Padua, is the principal professor of philosophy, whom I have repeatedly and urgently requested to look at the moon and planets through my glass, which he pertinaciously refuses to do. Why are you not here ? what shouts of laughter we should have at this glorious folly ! and to hear the professor of philosophy at Pisa labouring before the grand duke with logical arguments, as if with magical incantations, to charm the new planets out...
Sida 209 - What is man, that thou art mindful of him? and the son of man, that thou visitest him? For thou hast made him a little lower than the angels, and hast crowned him with glory and honour. Thou madest him to have dominion over the works of thy hands ; thou hast put all things under his feet...
Sida 181 - ... by spans — that seemed ghostly from infinitude. Without measure were the architraves, past number were the archways, beyond memory the gates. Within were stairs that...
Sida 280 - ... it is easy to see that, in the one case, our year would change its character, producing a far greater irregularity in the distribution of the solar heat ; in the other, our satellite must fall to the earth, occasioning a dreadful catastrophe. If the positions of the planetary orbits, with respect to that of the earth, were to change much, the planets might sometimes come very near us, and thus increase the effect of their attraction beyond calculable limits. Under such circumstances, ' we might...
Sida 243 - That the meteors of November 13 consisted of portions of the extreme parts of a nebulous body which revolves around the sun in an orbit interior to that of the earth, but little inclined to the plane of the ecliptic, having its aphelion near to the earth's path, and having a periodic term of 182 days nearly.
