Page 13 - But such a personification of "force" is a remnant of barbaric thought, in no wise sanctioned by physical science. When astronomy speaks of two planets as attracting each other with a " force " which varies directly as their masses and inversely as the squares of their distances...
Page 19 - ... European astronomers, was first seen ? Was it not by an American telescope that the companion of Sirius, the brightest star in the heavens, was revealed, and the mathematical prediction of the cause of his perturbations verified ? Was it not by a Yale College professor that the showers of shootingstars were first scientifically discussed, on the occasion of the grand American display of that meteoric phenomenon in 1833 ? Did we not join in the investigations respecting terrestrial magnetism instituted...
Page 17 - In many of the addresses that have been made during the past summer, on the Centennial occasion, the shortcomings of the United States in extending the boundaries of scientific knowledge, especially in the physical and chemical departments, have been set forth. " We must acknowledge with shame our inferiority to other people," says one. " We have done nothing," says another. Well, if all this be true, we ought, perhaps, to look to the condition of our colleges for an explanation. But we must not...
Page 5 - God-like. Mr. Baines, writing in 1833, states that the length of yarn spun in one year was nearly five thousand millions of miles, sufficient to pass round the earth's circumference more than two hundred thousand times — sufficient to reach fifty-one times from the earth to the sun.
Page 20 - Can an impartial person read without pain the characters which we so often attribute to our most illustrious citizens in political, and what is worse, in social life ? Can we complain if strangers accept us at our own depreciation, whether of men or things ? We need not go far to detect the origin of all this — it is in our political condition. Here wealth, power, preferment — preferment even to the highest position in the...
Page 18 - Was there any selfishness in that mission which a citizen of New York sent to equatorial Africa for the finding and relief of Livingstone, any in the astronomical expedition to South America, any in that to the valley of the Amazon? Was there any in the sending out of parties for the observation of the total eclipses of the sun? It was by American astronomers that the true character of his corona was first determined. Was there any in the seven expeditions that were dispatched for observing the transit...
Page 18 - Biela's comet was first detected, here that the eighth satellite of Saturn was discovered, here that the dusky ring of that planet, which had escaped the penetrating eye of Herschel and all the great European astronomers, was first seen? Was it not by an American telescope that the companion of Sirius, the brightest star in the heavens, was revealed, and the mathematical prediction of the cause of his perturbations verified ? Was it not by a Yale College professor that...
Page 17 - We must acknowledge with shame our inferiority to other people," says one. " We have done nothing," says another. Well, if all this be true, we ought perhaps to look to the condition of our colleges for an explanation. But we must not forget that many of these humiliating accusations are made by persons who are not of authority in the matter ; who, because they are ignorant of what has been done, think that nothing has been done. They mistake what is merely a blank in their own information for a...
Page 19 - Of chemistry, it may truly be affirmed that nowhere are its most advanced ideas, its new conceptions, better understood or more eagerly received. But how useless would it be for me to attempt a description in these few moments of what Prof. Silliman, in the work to which I have already referred, found that he could not include on more than...
Page 5 - ... from the earth to the sun. It would encircle the earth's orbit eight and a half times. The wrought fabrics of cotton exported in one year w^ould form a girdle for the globe, passing eleven times round the equator, and more than sufficient to form a continuous sheet from the earth to the moon." And let us not forget that to give commercial value to this vast result the capital chemical discovery of bleaching by chlorine was essential. Such was the condition of things in England just previously...
