Σελίδα 540 - I went into the cube and lived in it, using lighted candles, electrometers, and all other tests of electrical states. I could not find the least influence upon them, or indication of anything particular given by them, though all the time the outside of the cube was powerfully charged, and large sparks and brushes were darting off from every part of its outer surface.
Σελίδα 530 - There is a river in the ocean. In the severest droughts it never fails, and in the mightiest floods it never overflows. Its banks and its bottom are of cold water, while its current is of warm. The Gulf of Mexico is its fountain, and its mouth is in the Arctic Seas. It is the Gulf Stream.
Σελίδα 41 - Every body continues in its state of rest or of uniform motion in a straight line, except in so far as it may be compelled by impressed forces to change that state.
Σελίδα 11 - More generally, the moment of a force about a point is the product of the force by the length of the perpendicular dropped upon, it from the point.
Σελίδα 530 - ... bottom are of cold water, while its current is of warm; the Gulf of Mexico is its fountain, and its mouth is in the Arctic Seas. It is the Gulf Stream. There is in the world no other such majestic flow of waters. Its current is more rapid than the Mississippi or the Amazon, and its volume more than a thousand times greater.
Σελίδα 912 - R' P', SP, will have a constant ratio; or the sines of the angles of incidence and refraction are in a constant ratio.
Σελίδα 176 - The separate pressures can easily be calculated by Boyle's law, when the original pressure and volume of each gas are known. For example, let V and P, V...
