الصفحة 86 - Farewell! a long farewell, to all my greatness! This is the state of man: today he puts forth The tender leaves of hope; tomorrow blossoms, And bears his blushing honours thick upon him; The third day comes a frost, a killing frost, And when he thinks, good easy man, full surely His greatness is a-ripening, nips his root, And then he falls, as I do.
الصفحة 44 - The change of motion is proportional to the motive force impressed ; and is made in the direction of the right line in which that force is impressed.
الصفحة 43 - Every body continues in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed upon it.
الصفحة 149 - Vice, for vice is necessary to be shewn, should always disgust.} nor should the graces of gaiety, or the dignity of courage, be so united with it as to reconcile it to the mind. Wherever it appears, it should raise hatred by the malignity of its practices, and contempt by the meanness of its stratagems ; for while it is supported by either parts or spirit, it will be seldom heartily abhorred.
الصفحة 296 - When any one heareth the word of the kingdom, and understandeth it not, then cometh the wicked one, and catcheth away that which was sown in his heart.
الصفحة 52 - ... an equal reaction; therefore the planet B will, on the other hand, gravitate towards all the parts of the planet A; and its gravity towards any one part will be to the gravity towards the whole as the matter of the part to the matter of the whole. QED Cor.
الصفحة 149 - The purpose of these writings is surely not only to show mankind, but to provide that they may be seen hereafter with less hazard ; to teach the means of avoiding the snares which are laid by TREACHERY for INNOCENCE, without infusing any wish for that superiority...
الصفحة 41 - Absolute, true, and mathematical time, of itself, and from its own nature, flows equably without relation to anything external, and by another name is called duration: relative, apparent, and common time, is some sensible and external (whether accurate or unequable) measure of duration by the means of motion, which is commonly used instead of true time; such as an hour, a day, a month, a year.
الصفحة 42 - The effects which distinguish absolute from relative motion are the forces of receding from the axis of circular motion. For there are no such forces in a circular motion purely relative, but in a true and absolute circular motion they are greater or less, according to the quantity of the motion.
الصفحة 149 - If the world be promiscuously described, I cannot see of what use it can be to read the account; or why it may not be as safe to turn the eye immediately upon mankind, as upon a mirror which shows all that presents itself without discrimination.
