Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Interferometer Experiments in Acoustics and Gravitation In Chapter V, on the direct interferometry measurements of the compression of a sound-wave, much of my work has been superfluous, as it was anticipated in an admirable paper by Raps, using the Jamin interferometer. I have therefore given only as much as is necessary for the coordination of the other chapters. My method, however, is, I think, superior, owing to its much greater flexibility and the ease with which fringes in any orientation may be produced and shortened to a string of silvery beads. The simple organ-pipe blower or adjustable embouchure much used in the chapter will, I think, be found serviceable for many purposes, both of research and instruction. As the telephone is an indispensable convenience throughout these chapters, it was thought necessary to begin an interferometer investigation on the vibrations of the plate of that remarkable instrument. What comes out definitely in the research, Chapter V, is the readiness of the plate to quiver in overtones. A small mirror at the center is not therefore displaced, as a rule, translationally, but rather rotationally, giving rise to very complicated wave-forms, difficult to analyze. In corroboration of this, it was found (in Chapters IV and V, for instance) that a telephone current may often be commutated. In the endeavor to place the Foucault mirror on the interferometer I have thus far, for incidental reasons, failed of achievement; but as different apparatus useful in experiments of the present kind were tried out in the course of the work, I have given a brief account of it in Chapter VII. In Chapters VIII and IX, in deference to the wishes of Dr. R.S. Woodward, I have begun a search for methods of measuring the acceleration of gravity other than those classically in use. Such an inquiry necessarily consists in referring gravitational forces to forces generated in other mechanisms. An interferometer torsion-balance is first tested, but the results are found to contain relatively large and uncontrollable temperature coefficients, both of rigidity and viscosity, even if the ordinary effects of viscosity can be allowed for. The other (pneumatic) method for g, in which gravitational pull is referred to the pressure of a gas, has at the outset much to recommend it, for it admits of rough handling in spite of the otherwise surprising precision of results. The two errors which offer a serious menace to the accurate hydraulic weighing of the Cartesian diver, viz, the diffusion and solution discrepancies, though at first approach apparently insuperable, may not remain so indefinitely. At least, in experiments on the diffusion and convection of gases in narrow tubes, made in the lapse of years, coefficients of a negligibly small order of value were obtained. Though the work is very laborious, I think it will be worth while to carry it further. The remainder of the volume is largely concerned with work (Chapters XI and Xii) bearing on the constant of gravitation. The object of these experiments was at the outset a mere endeavor to read the deflections of the gravitation needle by displacement interferometry. The plan succeeded at once, almost beyond my expectations; but on computing the Newtonian constant it came out actually several times too large.

Available in PDF, EPUB and Kindle. Book excerpt: From the PREFACE. The experiments of the present volume are either direct applications of displacement interferometry or they embody the correlative work which has grown out of such applications, often at widely different times. In the arrangement of the chapters it has therefore been expedient to depart from chronological order in favor of an arrangement of subjects which belong together. In a former report I had already used a U-tube in connection with the interferometer, but the design of the apparatus was limited in scope. In the present paper (Chapter I) the open mercury manometer is made directly available for pressure measurement, and as the attainable sensitiveness is easily a few hundred thousandths of a centimeter of mercury per fringe displacement, it is well worth while to see what can be gained by using it. The applications to air thermometry on a micrometric scale and an attempt to revive the old absolute electrometer in Chapter II are merely incidental....

This book was released on 2007-10 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: PREFACE. THE Author of this very practical treatise on Scotch Loch - Fishing desires clearly that it may be of use to all who had it. He does not pretend to have written anything new, but to have attempted to put what he has to say in as readable a form as possible. Everything in the way of the history and habits of fish has been studiously avoided, and technicalities have been used as sparingly as possible. The writing of this book has afforded him pleasure in his leisure moments, and that pleasure would be much increased if he knew that the perusal of it would create any bond of sympathy between himself and the angling community in general. This section is interleaved with blank shects for the readers notes. The Author need hardly say that any suggestions addressed to the case of the publishers, will meet with consideration in a future edition. We do not pretend to write or enlarge upon a new subject. Much has been said and written-and well said and written too on the art of fishing but loch-fishing has been rather looked upon as a second-rate performance, and to dispel this idea is one of the objects for which this present treatise has been written. Far be it from us to say anything against fishing, lawfully practised in any form but many pent up in our large towns will bear us out when me say that, on the whole, a days loch-fishing is the most convenient. One great matter is, that the loch-fisher is depend- ent on nothing but enough wind to curl the water, -and on a large loch it is very seldom that a dead calm prevails all day, -and can make his arrangements for a day, weeks beforehand whereas the stream- fisher is dependent for a good take on the state of the water and however pleasant and easy it may be for one living near the banks of a good trout stream or river, it is quite another matter to arrange for a days river-fishing, if one is looking forward to a holiday at a date some weeks ahead. Providence may favour the expectant angler with a good day, and the water in order but experience has taught most of us that the good days are in the minority, and that, as is the case with our rapid running streams, -such as many of our northern streams are, -the water is either too large or too small, unless, as previously remarked, you live near at hand, and can catch it at its best. A common belief in regard to loch-fishing is, that the tyro and the experienced angler have nearly the same chance in fishing, -the one from the stern and the other from the bow of the same boat. Of all the absurd beliefs as to loch-fishing, this is one of the most absurd. Try it. Give the tyro either end of the boat he likes give him a cast of ally flies he may fancy, or even a cast similar to those which a crack may be using and if he catches one for every three the other has, he may consider himself very lucky. Of course there are lochs where the fish are not abundant, and a beginner may come across as many as an older fisher but we speak of lochs where there are fish to be caught, and where each has a fair chance. Again, it is said that the boatman has as much to do with catching trout in a loch as the angler. Well, we dont deny that. In an untried loch it is necessary to have the guidance of a good boatman but the same argument holds good as to stream-fishing...
