Hardback. Condition: New. Special edition. South of a forbidding range of mountain peaks lies a land of boundless resources and untold opportunity. The Mwangi Expanse has been home to an untold diversity of cultures and peoples since time immemorial, hosting powerful, isolated city states that have often paid little attention to… their neighbors. Yet the turning tides of fortune have begun to usher in changes that are rippling across the world. As a band of scholars from an ancient university venture north to aid a disaster-torn Avistan. A revolution-forged nation seeks powerful allies against foreign aggression. An undead god, once a symbol of hope to his declining nation, now grows jealous enough to turn on his self-proclaimed kin. Whether you are a diplomat seeking leverage from the most difficult of positions, a spy seeking the subtlest hint of danger from your surroundings, a guardian hoping to protect your home and people, or a warrior striking back at tyrants both native and foreign, this guide to the Mwangi Expanse offers you the ultimate resource to explore a realm of magic, monsters, and intrigue!

Taschenbuch. Condition: Neu. Neuware - 'The Physical Review Supplement' serves as a pivotal compendium of scientific discourse during one of the most transformative eras in modern physics. Curated by distinguished figures such as A.H. Compton, E.C. Kemble, and K.T. Compton, this volume captures the rigorous intellectual environm…ent of the late 1920s, providing a platform for groundbreaking research and theoretical advancements. As a precursor to specialized scientific reviews, this supplement offers deep insights into the evolving understanding of atomic structures, radiation, and quantum mechanics.The work reflects the rapid acceleration of scientific discovery, documenting the transition from classical physics to the quantum revolution. Readers will find sophisticated analyses and experimental reports that laid the groundwork for contemporary physical sciences. Its historical significance is underscored by the involvement of Arthur H. Compton, whose pioneering work redefined the field. 'The Physical Review Supplement' remains an essential resource for historians of science, physicists, and scholars interested in the academic foundations of modern studies regarding energy and matter. This collection is a testament to the collaborative spirit and intellectual rigor that defined early 20th-century American scientific inquiry.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it. This work was reproduced from the original artifact, and remains as true to the original work as possible.

Contact seller4-star seller46 signed letters [34 TLS, 12 ALS] comprising decades of correspondence between Frederick Gardner Cottrell and various notable figures of his day in U.S. politics, the international science community, and academia. All letters are housed in new archival mylar sleeves. Cottrell was a notable chemist, inventor, and philanthropist,… best known today for his invention of the electrostatic precipitator - one of the first inventions to combat air pollution - and his founding of the Research Corporation for Science Advancement, which used the revenue from the electrostatic precipitator to fund further scientific research, and continues to do so today. While best remembered for these feats, Cottrell had a long and influential career both in the U.S. Federal Government and as a science consultant. He was well known nationally and internationally - in industry, in government, and in academia - for his support of and contributions to new ideas and new talent within the scientific community. The letters, which span from 1901-1941, track Cottrell over the course of 40 years, and evidence the many relationships he had over that period with some of the most influential people of the time. These include a letter of introduction from Alexander Graham Bell, a discussion of chemistry with Thomas Edison, replies from two Nobel Prize winning scientists - the discoverer of the noble gasses, William Ramsay, and discoverer of the electron, J. J. Thomson - to Cottrell's request to study in their labs, and exchanges with two presidents, Herbert Hoover and Woodrow Wilson. Other letters show his personal interactions with leading scientists of his day (Robert J. Van de Graaff, Georges Claude, George E. Hale) and heads of industry (Henry L. Doherty, Ivy Lee), and track the path of his career through his time as the director of the Bureau of Mines; to chairman of the Division of Chemistry and Chemical Technology on the National Research Council; to head of the U.S. Department of Agriculture's Fixed Nitrogen Research Lab, and beyond. These letters, the vast majority of which were sent by these notable figures to Cottrell, evidence his expertise, the depth and breadth of his professional interests, and his eagerness to collaborate and share research and ideas, coming together to trace the life of a man whose work was and continues to be consequential to the advancement of science as a whole. Shelved case 1. CONTENTS: 1-Page TLS from inventor of the telephone Alexander Graham Bell to a Mr. Fish, dated December 20, 1911, introducing Cottrell to him. In Very Good condition. In this letter, Bell is writing in his capacity as Regent of the Smithsonian Institution. On 1331 Connecticut Avenue letterhead. Faintly creased, with mild wrinkling along the edges. Signed in black ink by Bell: "Alexander Graham Bell". 1-page TLS from inventor of the light bulb Thomas Edison to Cottrell dated January 13, 1925, discussing the unexpected results of a past chemistry experiment of his in relation to the generation of ammonia. In Very Good condition. TLS is on Edison's personal letterhead ("From the Laboratory of Thomas A. Edison"). Lightly age toned, with some wrinkling and small closed tears along the top edge. Faintly creased from past folding. Signed by Edison in black ink: "Thos. A. Edison". Includes a lightly soiled 1-page facsimile of Cottrell's reply. 2-page ALS from Nobel Prize winning physicist Joseph John Thomson to an unnamed recipient, likely Cottrell, dated July 6, 1901, discussing the possibility of Cottrell coming to study at Thomson's lab. In Very Good condition. In 1901, Cottrell would have been studying in Europe at the University of Berlin, seeking to study in the laboratory of an accomplished scientist. Thomson was already a figure of some renown for his 1897 discovery of the electron, which represented the first identification of a subatomic particle, and would be awarded the 1906 Nobel Prize in Physics in recognition of his work. ALS is on Cavendish Laborat. Signed.
