Most of theE xercises described mthis book have been used by the writer for a long time as a laboratory accompaniment to a general course of lectures and text -book study extending through one college year. The students formal weekly engagements in this course are two lectures and one two-hour laboratory exercise. A part of the lecture hom is often taken, for a brief oral or written examination of the class on matters treated in the textbook or in the laboratory. These Exercises do not profess to give training in exact measurement. Their primary object is first-hand acquaintance with a wide range of important facts, principleS; and apparatus, or machines. In such exercises the students must often work in groups of considerable size with a single piece or set of apparatus; for example, it is impracticable to supply a steam-engine for every student or every pair of students making up a laboratory section of, let us say, sixteen members. But it should be the constant endeavor of the teacher to provide individual work and to foster individual responsibility, wherever this can be done, by reduplication of the less elaborate and expensive apparatus or by the definite division of labor in complicated operations.

Leopold is delighted to publish this classic book as part of our extensive Classic Library collection. Many of the books in our collection have been out of print for decades, and therefore have not been accessible to the general public. The aim of our publishing program is to facilitate rapid access to this vast reservoir of literature, and our view is that this is a significant literary work, which deserves to be brought back into print after many decades. The contents of the vast majority of titles in the Classic Library have been scanned from the original works. To ensure a high quality product, each title has been meticulously hand curated by our staff. This means that we have checked every single page in every title, making it highly unlikely that any material imperfections – such as poor picture quality, blurred or missing text - remain. When our staff observed such imperfections in the original work, these have either been repaired, or the title has been excluded from the Leopold Classic Library catalogue. As part of our on-going commitment to delivering value to the reader, within the book we have also provided you with a link to a website, where you may download a digital version of this work for free.

(This book was originally published prior to 1923, and rep...)
This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.

physicist university professor
Hall, Edwin Herbert was born on November 7, 1855 in Gorham, Maine, United States. Son of Joshua E. and Lucy Ann (Hilborn) Hall.
He did his graduate schooling and research, and earned his Doctor of Philosophy degree (1880), at the Johns Hopkins University where his seminal experiments were performed.
Hall conducted thermoelectric research at Harvard and also wrote numerous physics textbooks and laboratory manuals. Hall did his undergraduate work at Bowdoin College, Brunswick, Maine, graduating in 1875. He was the principal of Gould Academy in 1875–1876 and the principal of Brunswick High School in 1876–1877.
The Hall effect was discovered by Hall in 1879, while working on his doctoral thesis in Physics.
Hall"s experiments consisted of exposing thin gold leaf (and, later, using various other materials) on a glass plate and tapping off the gold leaf at points down its length. The effect is a potential difference (Hall voltage) on opposite sides of a thin sheet of conducting or semiconducting material (the Hall element) through which an electric current is flowing.
This was created by a magnetic field applied perpendicular to the Hall element. The ratio of the voltage created to the amount of current is known as the Hall resistance, and is a characteristic of the material in the element.
In 1880, Hall"s experimentation was published as a doctoral thesis in the American Journal of Science and in the Philosophical Magazine.
Hall was appointed as Harvard"s professor of physics in 1895. Hall retired in 1921 and died in Cambridge, Massachusetts, United States. in 1938. The Hall effect is used in magnetic field sensors, present in a large number of devices.
In the presence of large magnetic field strength and low temperature, one can observe the quantum Hall effect, which is the quantization of the Hall resistance.
This is now the official standard for electrical resistance. List of eponyms
