4. Crystals have usually the form of hexagonal or rhomb-shaped scales, plates or prisms, with r is bounded by the basal pinacoid c (ooi) parallel to which is the perfect cleavage, the clinopinacoid b ((D10) parallel to the For instance, those of a ternary form involve two classes which may be geometrically interpreted as point and line co-ordinates in a Thus what have been called seminvariants are not all of them invariants for the general substitution, but are invariants for the particular substitution xl = X11 + J-s12, X 2 = 112 Again, in Christianity swept the whole discussion on to a higher The combined mass of the earth and moon admits of being determined by its effect in changing the position of the Upon one of these is based the principle of the mariner's compass, which is said to have been known to the Chinese as early as I ioo B.C., though it was not introduced into Europe until more than 2000 years later; a magnet supported so that its axis is free to turn in a horizontal The compass needle is a little steel magnet balanced upon a pivot; one end of the needle, which always bears a distinguishing mark, points approximately, but not in general exactly, to the north,' the vertical ir`"' lines of force," of which the curves formed by the filings afford a rough indication; Faraday's lines are howeve confined to the For the practical observation of this phenomenon it is usual to employ a needle which can turn freely in the The magnetic field due to a long straight wire in which a current of electricity is flowing is at every point at right angles to the The equipotential surfaces are two series of ovoids surrounding the two poles respectively, and separated by a The magnetic needle may be cemented horizontally across the back of a little 8, where AB is the vertical rod and M indicates the position of the magnetometer needle, which is supposed to be perpendicular to the If a coil of insulated wire is suspended so that it is in stable equilibrium when its The intensity of a field may be measured by the rotation of the But the application of a magnetic field at right angles to the It can be shown that if a current i circulates in a small It may be added that he first examined the conditions of stability of the system formed by Saturn's rings, pointed out the necessity for their rotation, and fixed for it a period (Io h 33 m) virtually identical with that established by the observations of Herschel; that he detected the existence in the solar system of an invariable Laplace treated the subject from the point of view of the gradual aggregation and cooling of a mass of matter, and demonstrated that the form which such a mass would ultimately assume must be an ellipsoid of revolution whose equator was determined by the primitive If ABCD is a tetrahedron of reference, any point P in space is determined by an equation of the form (a+13+ - y+5) P = aA+sB +yC +SD: a, a, y, b are, in fact, equivalent to a set of homogeneous coordinates of P. For constructions in a fixed We will now consider in detail the important case in which uniform We imagine a wave-front divided o x Q into elementary rings or zones - often named after Huygens, but better after Fresnelby spheres described round P (the point at which the aggregate effect is to be estimated), the first sphere, touching the An interesting exception to the general rule that full brightness requires the existence of the first zone occurs when the obstacle assumes the form of a small circular disk parallel to the The amplitude of the light at any point in the axis, when What is seen through the eye-piece in any case is the same as would be depicted upon a screen in the focal By the principle of energy the illumination over the entire focal If the aperture be increased, not only is the total brightness over the focal It has already been suggested that the principle of energy requires that the general expression for I 2 in (2) when integrated over the whole of the In these expressions we are to replace p by ks/f, or rather, since the diffraction pattern is symmetrical, by kr/f, where r is the distance of any point in the focal when the wave-surface deviates at each end by a quarter wave-length from the true If the source be a point or a line, and a collimating lens be used, the incident waves may be regarded as It may be worth while to examine further the other variations from correct ruling which correspond to the various terms expressing the deviation of the wave-surface from a perfect If we suppose that everything is symmetrical on the two sides of the primary It may be remarked that these calculations apply to the rays in the primary In Rowland's dividing engine the screws were prepared by a special process devised by him, and the resulting gratings, In theoretical investigations these problems are usually treated as of two dimensions only, everything being referred to the When, in order to apply Huygens's principle, the wave is supposed to be broken up, the phase is the same at every element of the surface of resolution which lies upon a line perpendicular to the These equations simplify very much in their application to " Let E = o,7 7 = o, =f (bt - x) be the displacements corresponding to the incident light; let O l be any point in the Then the displacement at 0 will take place in a direction perpendicular to 0 1 0, and lying in the (5), of polarized light are executed in a direction perpendicular to the Imagine a flexible lamina to be introduced so as to coincide with the The conception of the lamina leads immediately to two schemes, according to which a primary wave may be supposed to be broken up.
