Side 142 - If I have seen farther, it is by standing on the shoulders of giants.
Side 148 - Are not all hypotheses erroneous in which light is supposed to consist in pression or motion propagated through a fluid medium? If it consisted in pression or motion, propagated either in an instant, or in time, it would bend into the shadow.
Side 72 - I am purposing them to be considered of and examined on account of a philosophical discovery, which induced me to the making of the said telescope, and which I doubt not but will prove much more grateful than the communication of that instrument, being, in my judgment, the oddest if not the most considerable detection which hath hitherto been made in the operations of nature.
Side 267 - Harmonics ; what I had promised my friends in the title of this book, which I named before I was sure of my discovery ; what, sixteen years ago, I urged as a thing to be sought ; that for which I joined Tycho Brahe, for which...
Side 201 - Are not the rays of light in passing by the edges and sides of bodies bent several times backWards and forwards with a motion like that of an eel? And do not the three fringes of light above mentioned arise from three such bendings ?" The idea thus indistinctly thrown out in the preceding queries has been ingeniously interpreted by Mr.
Side 75 - Hence, therefore, it comes to pass, that whiteness is the usual colour of light; for light is a confused aggregate of rays indued with all sorts of colours, as they are promiscuously darted from the various parts of luminous bodies.
Side 441 - The third I now design to suppress. Philosophy is such an impertinently litigious lady, that a man had as good be engaged in lawsuits as have to do with her.
Side 238 - ... fancy, which I must confess is too hard a knot for me to untie. To place this effect in a constant motion is hard, because the sun ought then to appear perpetually It seems rather to consist in a disposition of the sensorium to move the imagination strongly, and to be easily moved both by the imagination and by the light as often as bright objects are looked upon.
Side 442 - Now is not this very fine ? Mathematicians, that find out, settle, and do all the business, must content themselves with being nothing but dry calculators and drudges ; and another, that does nothing but pretend and grasp at all things, must carry away all the invention, as well of those that were to follow him, as of those that went before.
Side 96 - I see I have made myself a slave to Philosophy, but if I get free of Mr Linus' business I will resolutely bid adieu to it eternally, except what I do for my private satisfaction or leave to come out after me. For I see a man must either resolve to put out nothing new or to become a slave to defend it...
