Photocopies of Physicist Erwin Schrödinger letters to Wilhelm Wien from originals owned by Dr. Philip H. K. Siebertz of Munich, Germany. These letters were not included in the microfilmed correspondence for the Archive for the History of Quantum Physics (See RLIN entry PAAV86-A21).

This is Cassidy's doctoral dissertation for Purdue University.

This dissertation reveals how Joseph Henry's teaching related to his research, and how it reflected his overall scientific outlook and affected developments in physics.

These 32 research lab notebooks are filled with diverse types of documentation on his x-ray and cosmic ray research.

These excerpts were brought together by Slater from his files, at the request of Dr. Leon Rosenfeld, to document Slater's visit to Copenhagen, and Bohr's Lab. In general, the letters concern quantum physics.

These papers include correspondence, notes, lectures, articles, and clippings pertaining to scientific matters.

This volume was presented to Benjamin Franklin, and contains chapters on electricity, fire, air, water, earth, and earthquakes.

These letters to Hunt concern geology, physics (photography and light), and scientific instruments.

These letters are from Rutherford to Bertram Borden Boltwood, the Yale University chemist who worked with Rutherford on his scientific study of radioactivity and the structure of the atom. There is much information concerning professional activities and colleagues.

In this dissertation Saunders shows that Einstein's "1905 theory" restricts the number of permissible models of an ether.

These are letters and postcards on scientific and personal matters, with a long letter (1958) about Fermi's career from Adolfo Amidei to Emilio Segrè.

This volume, written by an unknown author, describes general principles of physics, with numerous sketches illustrating the text. There are a few notations in Spanish by Juan Bastolleros.

These contain a few notes and memoranda by Van Vleck, but the bulk of the collection is letters to and from him. Correspondents include Raymond T. Birge, Gerhard H. Dieke, Paul A. M. Dirac, Edwin C. Kemble, and Robert S. Mulliken.

This collection contains drafts of letters and copies of enclosures from Richardson and letters and enclosures from approximately 3500 authors. Represented are almost all the Nobel Laureates in physics before 1950.

These letters are to and from Planck. Correspondents include Hans Thacher Clarke, Gerard Peter Kuiper, and Raymond John Seeger.

Val Logsdon Fitch, (1923-2015)was born on March 10, 1923, in Merriman, Nebraska, in the remote Sandhills region in the north of the state. During WWII, he was drafted and sent to Los Alamos, N.M., to work as a technician on the Manhattan Project. While there, he helped design the detonator for the atomic bomb that was tested at Alamogordo and later dropped on Nagasaki, Japan. He shared the 1980 Nobel Prize in Physics with James Cronin for work that revealed a surprising imbalance in the laws of nature and helped explain why the collision of matter and antimatter has not destroyed everything in the universe. Their discovery of CP (charge parity invariance) violation was the result of experiments that included four objectives: to test the anomalous results of Adair, et al, to study the regeneration phenomena under a variety of conditions in different materials, to set new limits on the decay of the long-lived neutral K to two pions, and to check for the presence of neutral currents in strangeness changing decays. The Val Logsdon Fitch Papers include his research of K mesons, the innovation of the velocity-selecting Cherenkov counter that separated K+ from protons and pions in the beam, neutral kaons, CP violation in proton-antiproton interactions, the 'gap' method invented by Fitch to take measurements of KL - KS mass difference, a search for short-distance gravitational forces and finally, strange dibaryons. Dr. Fitch used particle accelerators to perform his experiments including the Bevatron, the Cosmotron, the accelerator at the Fermilab and the superconducting super collider at CERN, Geneva, Switzerland. The collection is divided into XV Series.

This collection includes correspondence, notebooks, and memorandum books, lecture notes, published and miscellaneous papers, and academic and military records.

The first volume contains mathematical problems, which appear to be college exercises (1814); the second volume is an essay on the projection of the sphere and spherical trigonometry, including an appendix on astronomy (1812); and the third volume is a lecture on natural philosophy, apparently prepared for delivery [n.d.].

These classroom notes, taken by an unidentified student, present the state of knowledge in natural philosophy, especially astronomy, during these years. There are mentions of many contemporary scientists, and much on Newton and Newtonian philosophy.
