Synopsis
Excerpt from A B C of Hydrodynamics
This little book has no pretensions to being a treatise on hydrodynamics. It is, as its title implies, only intended as an introduction to the study of that subject. There is not very much that is new in it; some of the quotations are so old that they have been forgotten, and so will appear to the reader of the ordinary text-books as if they were new. What is, I fancy, original is the way in which the matter is arranged and the subject presented. Instead of treating of the movement of a "perfect liquid" and then informing the reader that ordinary liquids behave quite differently, I have endeavoured to show that perfect and imperfect (?) liquids follow exactly the same laws, and under similar conditions move in a similar manner.
The difficulties are generally supposed to be very great. Sir John Herschel told us that "if there be one part of dynamic science more abstruse and unapproachable than another, it is the doctrine of propagation of motion in fluids, and especially in elastic fluids like the air, even where the amount and application of the original acting forces are known and calculable." These difficulties are, I think, very largely artificial ones. It is well to remember what Dubuat said more than a hundred years ago: "On risque souvent de se tromper, quand on applique aux fluides les lois du mouvement qui conviennent aux solides." I might even go further and say that, when thinking of liquids, what (to the untrained mind) appears "obvious" or "appeals to common sense" is very frequently wrong - more frequently, perhaps, than not. When the student has trained himself to "think in pressures" many difficulties will disappear.

"Next to being right in this world, the best of all things is to be clearly and definitely wrong, because you will come out somewhere. If you go buzzing about between right and wrong, vibrating and fluctuating, you come out nowhere; but if you are absolutely and thoroughly and persistently wrong, you must, some of these days, have the extreme good fortune of knocking your head against a fact, and that sets you all straight again." —Huxley

A B C of Hydrodynamics (Classic Reprint)
impression à la demandeVendeur : Forgotten Books, London, Royaume-Uni
Évaluation du vendeur 5 sur 5 étoiles
Paperback. Etat : New. Print on Demand. This book delves into the fundamentals of hydrodynamics, exploring the resistance encountered by objects moving through liquids. The author presents a clear and non-mathematical explanation of how resistance is generated, challenging the traditional view that a body moving in a perfect liquid would experience no resistance. Drawing on the works of Newton, Lord Rayleigh, and other notable scientists, the book examines the distinction between perfect and imperfect liquids, emphasizing that both types follow the same laws of motion and exhibit similar resistance patterns under comparable conditions. The author's unique perspective sheds light on the complexities of liquid resistance, providing valuable insights for students, engineers, and anyone interested in understanding the behavior of liquids in motion. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N° de réf. du vendeur 9781332223770_0
