James Dwight Dana 1813-1895
NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA BIOGRAPHICAL MEMOIRS PART OF VOLUME IX BIOGRAPHICAL MEMOIR OF JAMES DWIGHT DANA 1813-1895 BY LOUIS V. PIRSSON PRESENTED TO THE ACADEMY AT THE ANNUAL MEETING, 1919 CITY OF WASHINGTON PUBLISHED BY THE NATIONAL ACADEMY OF SCIENCES December, 1919 JAMES DWIGHT DANA 1813-1895 BY LOUIS V. PIRSSON INTRODUCTION If it appears strange that over twenty years should have elapsed since the death of the noted geologist, James Dwight Dana, before a biographical memoir of his life and work should be presented to the members of this Academy, this has been due to a variety of circumstances, which need not be dwelt upon here. If we have on the one hand the feeling that this should have been done before, on the other there is the advan- tage that from the time that has passed we are enabled to enlarge our perspective and to see in a clearer light the char- acter of the man and the service which he rendered to Amer- ican science. During this period, also, a life of Dana and vari- ous biographical notices, together with estimates of him as a teacher and as a scientist, have appeared, and this material has been freely used by the writer, upon whom has fallen the privi- lege of presenting a memoir to the Academy of one of its founders and most distinguished members.* * The more important American biographical notices which have come to the attention of the writer are the following: James Dwight Dana, by Edward S.

Wikipedia Reader https://en.wikipedia.org/wiki/Aurora Selected by Julie Madsen - Entry 10 1 Aurora From Wikipedia, the free encyclopedia An aurora, sometimes referred to as a polar lights or north- ern lights, is a natural light display in the sky, predominantly seen in the high latitude (Arctic and Antarctic) regions.[1] Au- roras are produced when the magnetosphere is sufficiently disturbed by the solar wind that the trajectories of charged particles in both solar wind and magnetospheric plasma, mainly in the form of electrons and protons, precipitate them into the upper atmosphere (ther- mosphere/exosphere), where their energy is lost. The resulting ion- ization and excitation of atmospheric constituents emits light of varying color and complexity. The form of the aurora, occur- ring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating parti- cles. Precipitating protons generally produce optical emissions as incident hydrogen atoms after gaining electrons from the atmosphere. Proton Images of auroras from around the world, auroras are usually observed at including those with rarer red and blue lower latitudes.[2] lights Wikipedia Reader 2 May 1 2017 Contents 1 Occurrence of terrestrial auroras 1.1 Images 1.2 Visual forms and colors 1.3 Other auroral radiation 1.4 Aurora noise 2 Causes of auroras 2.1 Auroral particles 2.2 Auroras and the atmosphere 2.3 Auroras and the ionosphere 3 Interaction of the solar wind with Earth 3.1 Magnetosphere 4 Auroral particle acceleration 5 Auroral events of historical significance 6 Historical theories, superstition and mythology 7 Non-terrestrial auroras 8 See also 9 Notes 10 References 11 Further reading 12 External links Occurrence of terrestrial auroras Most auroras occur in a band known as the auroral zone,[3] which is typically 3° to 6° wide in latitude and between 10° and 20° from the geomagnetic poles at all local times (or longitudes), most clearly seen at night against a dark sky. -
Joseph Henry
MEMOIR JOSEPH HENRY. SIMON NEWCOMB. BEAD BEFORE THE NATIONAL ACADEMY OP SCIENCES, APRIL 21, 1880. (1) BIOGRAPHICAL MEMOIR OF JOSEPH HENRY. In presenting to the Academy the following notice of its late lamented President the writer feels that an apology is due for the imperfect manner in which he has been obliged to perform the duty assigned him. The very richness of the material has been a source of embarrassment. Few have any conception of the breadth of the field occupied by Professor Henry's researches, or of the number of scientific enterprises of which he was either the originator or the effective supporter. What, under the cir- cumstances, could be said within a brief space to show what the world owes to him has already been so well said by others that it would be impracticable to make a really new presentation without writing a volume. The Philosophical Society of this city has issued two notices which together cover almost the whole ground that the writer feels competent to occupy. The one is a personal biography—the affectionate and eloquent tribute of an old and attached friend; the other an exhaustive analysis of his scientific labors by an honored member of the society well known for his philosophic acumen.* The Regents of the Smithsonian Institution made known their indebtedness to his administration in the memorial services held in his honor in the Halls of Congress. Under these circumstances the onl}*- practicable course has seemed to be to give a condensed resume of Professor Henry's life and works, by which any small occasional gaps in previous notices might be filled. -

GEOMAGNETISM – A HISTORICAL REVIEW R. Sashikanth Assistant Professor and Head of the Department Department of Physics and Space Sciences Gandhi Institute of Technology and Management, Gangapada, Bhubhaneshwar, Odisha, India. E-mail : [email protected], [email protected] [email protected], [email protected] Abstract : This specific paper addresses the historical events that had led in the current scenario, to the development of one of the most important fundamental research areas – Geomagnetism, which might even date back to probably millions of years embedded in the core scientific aspects of even ancient civilizations. The solar wind and its associated magnetic field have their source in the Sun and their interaction with the geo-magnetic field which extends into outer space has its origin inside the earth’s core. Needless to say, the contributions of many scientific researchers on the dynamics of upper, middle and lower atmospheres of the earth is really outstanding and remarkable, but certain important aspects appear to have been missed. -

REDFIELD Any opinions expressed in this memoir are those of the author(s) and do not necessarily reflect the views of the National Academy of Sciences. Biographical Memoir COPYRIGHT 1976 NATIONAL ACADEMY OF SCIENCES WASHINGTON D.C. HENRY BRYANT BIGELOW October 3,1879-December 11,1967 BY ALFRED C. REDFIELD ENRY BRYANT BIGELOW was an accomplished systematic zool- H ogist, being a recognized authority on both the coelenter- ates and fishes. His 1911 paper on the siphonophores was considered to be the most useful report on this group that had ever been written. In recognition of his later work on the fishes of the western North Atlantic he was awarded the Daniel Giraud Elliot Medal by the National Academy of Sciences in 1948. Of wider impact on the development of marine science was his recognition of the interdependence of the physics, chem- istry, and biology of the sea, as exemplified by his studies of the Gulf of Maine and his part in the creation of the Woods Hole Oceanographic Institution, of which he was the first director. Seventy-five years ago, when Alexander Agassiz visited the Maldive Islands with Henry Bigelow as his assistant, oceanog- raphy in America was an interest promoted from time to time through individual initiative and, when in line with their pri- mary duties, by appropriate governmental agencies. Today it is a fully recognized division of science, complete with standard textbooks and special journals. -

DeFord, 1972, pp. 65-71 in: East-Central New Mexico, Kelley, V. C.; Trauger, F. D.; [eds.], New Mexico Geological Society 23rd Annual Fall Field Conference Guidebook, 236 p. This is one of many related papers that were included in the 1972 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.
