Σελίδα 338 - ... one case we are enlightened as to a host of others. The oscillating body may be an ironclad, or it may be an atom of hydrogen, the disturbing periodic force may be the waves of the Atlantic, or it may be the waves in the ether occurring five hundred millions of millions of times in a second; it is all one to the mathematician, the treatment is substantially the same. The question of the speed of ships and the power to propel them is probably more effectually treated by experiment on models, as...
Σελίδα 109 - ... proved to be erroneous by Mr. JB Eads, the projector of these works. The discussion in the controversial literature of that time was summarized in the " History of the Mississippi Jetties " (pp. 24-49). It was there shown that very little material was rolled along the bed of the Mississippi Eiver, in its lower reaches at least, and that the bar was formed almost entirely from the deposit of sediment held in suspension during the progress of the river towards the sea, which was dropped on account...
Σελίδα 347 - Admission to its sanctuary, and to the privileges and feelings of a votary, is only to be gained by one means, — sound and sufficient knowledge of mathematics, the great instrument of all exact inquiry, without which no man can ever make such advances in this or any other of the higher departments of science as can entitle him to form an independent opinion on any subject of discussion within their range.
Σελίδα 331 - A society for the general advancement of Mechanical Science, and more particularly for promoting the acquisition of that species of knowledge which constitutes the profession of a Civil Engineer...
Σελίδα 331 - June 19, 1905. acquisition of that species of knowledge which constitutes the profession of a civil engineer, being the art of directing the great sources of power in nature for the use and convenience of man, as the means of production and of traffic in states both for external and internal trade, as applied in the construction of roads, bridges, aqueducts, canals, river navigation, and docks, for internal intercourse and exchange, and in the construction of ports...
Σελίδα 312 - Institution shall be considered the property thereof, unless there shall have been some previous arrangement to the contrary, and the Council may publish the same, in any way and at any time they may think proper. But should the Council refuse, or delay the publication of such Paper, beyond a reasonable time, the Author thereof shall have a right to copy the same, and to publish it as he may think fit, having previously given notice, in writing, to the Secretary of his intention. No person shall...
Σελίδα 333 - ... will not tend to be in any way affected by the centrifugal force, but suppose the shaft becomes slightly bent, it is obvious to anyone that if the speed be enormously high this bending will increase, and go on increasing until the shaft breaks. In this case also we may use mathematical treatment ; we find that the condition of the shaft is expressed by a differential equation of the fourth order, and from consideration of the solution of this equation we can say that if the speed of any particular...
Σελίδα 347 - After all, in any department of applied or pure science the highest satisfaction comes from accomplishing that which no one has done before, from disclosing what no one hitherto has known. If a department of the Arts or Sciences ceases to advance and becomes simply the application in known ways of known principles to obtain known ends, that department has lost its charm till the time comes for a fresh advent of change and development. To effect such advances it is easy to show that mathematics is...
Σελίδα 33 - ... should vary in proportion to the rise of tide, and the distance to which the tide is propagated up the river ; but probably in most cases the suitable rate of enlargement seawards would be found to lie, on the average, between 1 in 80 and 1 in 40, with a more rapid widening near the outlet.
Σελίδα 344 - ... its neatest expression is by means of partial differential coefficients. The two most notable names in connection with the development of the second law of thermodynamics in harmony with the first are those of Kelvin and Clausius ; both dealt with the subject in a mathematical form not comprehensible to those who have not had substantial mathematical training. Illustrations such as these might be multiplied almost indefinitely. They show that the advancement of the Science of Engineering has...
