Page 33 - It was not until about the middle of the nineteenth century that the study of Euclid became common in the secondary schools of England.
Page 160 - The phenomena in these exhausted tubes reveal to physical science a new world — a world where matter may exist in a fourth state...
Page 23 - Chance has thrown in my way another Principle, more universal and remarkable than the preceding one, and which casts a new Light on the Subject of Electricity. This Principle is, that there are two distinct Electricities, very different from one another; one of which I call vitreous Electricity, and the other resinous Electricity. The first is that of Glass, Rock-Crystal, Precious...
Page 8 - Gilbert, physician to both Elizabeth I and James I of England. Gilbert spent 17 years experimenting with magnetism and, to a lesser extent, electricity. He assembled the results of his experiments and all of the available knowledge on magnetism in the treatise De Magnete. Magneticisque Corporibus, et de Magno Magnete Tellure ("On the Magnet and Magnetic Bodies, and on That Great Magnet the Earth"). As suggested by the title, Gilbert described the Earth as a huge magnet. He introduced the term electric...
Page 51 - The {Treat tendency of the attraction of the different chemical agents by the positive and negative surfaces in the Voltaic apparatus seems to be to restore the electrical equilibrium.
Page 58 - Let us now once, as the battery is in activity, try to place the wire parallel with the needle;' as this was made, he was quite struck with perplexity by seeing the needle making a great oscillation (almost at right angles with the magnetic meridian). Then he said, 'Let...
Page 87 - Sir Humphry Davy gave me the analysis to make as a first attempt in chemistry, at a time when my fear was greater than my confidence, and both far greater than my knowledge ; at a time, also, when I had no thought of ever writing an original paper on science.
Page 51 - ... cease. But solution of muriate of soda being composed of two series of elements possessing opposite electrical energies, the oxygen and the acid are attracted by the zinc, and the hydrogen and the alkali by the copper. The balance of power is momentary only; for solution of zinc is formed, and the hydrogen disengaged. The negative energy of the copper and the positive energy of the zinc are consequently again exerted, enfeebled only by the opposing energy of the soda in contact with the copper,...
Page xv - Without them there can be no effectual working. In Science, more perhaps than in any other study, the dead and the living are one. ' We, being many, are one body, and every one members one of another.
Page 174 - the atom as containing a large number of smaller bodies," which he calls "corpuscles," and these are equal to one another. "In the normal atom this assemblage of corpuscles forms a system which is electrically neutral.
