UCD: Physics 9D - Modern Physics
Tom Weideman · University of California, Davis
Physics 9D introduces the 20th-century topics of special relativity and quantum theory to science and engineering majors.

Radically Modern Introductory Physics Text I
David J. Raymond · New Mexico Tech
The idea for a “radically modern” introductory physics course arose out of frustration with the standard two-semester treatment of the subject. It is basically impossible to incorporate a significant amount of “modern physics” (meaning post-19th century!) in that format. The authors feel that an introductory physics course for non-majors should make an attempt to cover the great accomplishments of physics in the 20th century, since they form such an important part of our scientific culture.

Radically Modern Introductory Physics Text II
David J. Raymond · New Mexico Tech
The idea for a “radically modern” introductory physics course arose out of frustration with the standard two-semester treatment of the subject. Given this structure, a knowledgeable instructor able to offer one-on-one time with students (as in our recitation sections) is essential for student success. The text is most likely to be useful in a sophomore-level course introducing physics majors to the broad world of physics viewed from a modern perspective.

Electromagnetics and Applications
David H. Staelin · Massachusetts Institute of Technology
This text explores electromagnetic phenomena in modern applications, including wireless and optical communications, circuits, computer interconnects and peripherals, microwave communications and radar, antennas, sensors, micro-electromechanical systems, and power generation and transmission. Fundamentals include quasistatic and dynamic solutions to Maxwell's equations; waves, radiation, and diffraction; coupling to media and structures; guided waves; resonance; and acoustic analogs.

Physics 156 - A Cosmology Workbook
Lloyd Knox · University of California, Davis
By reading and also working through the exercises the student in their third or fourth year of a physics major will learn of the broad outlines of our modern conception of the cosmos. Subjects covered include space curvature, space expansion, redshifts, cosmological distance measures, Newtonian gravitational dynamics in an expanding universe, the contents of the cosmos including dark matter and dark energy, and observable relics of the hot and dense universe of 14 billion years ago.

Introduction to the Physics of Atoms, Molecules and Photons (Benedict)
Mihály Benedict · University of Szeged
These lecture notes have been prepared to give an introduction into the foundations of atomic and molecular physics with an emphasis on the interaction of these atomic systems with light, and in more general, with electromagnetic fields. Modern technology is based more and more on the laws and properties of micro-world, so it seems necessary to understand the most important rules and methods of this field of a physics student.

Spacetime Physics
Edwin F. Taylor & John Archibald Wheeler · Massachusetts Institute of Technology
Spacetime Physics embodies what the authors had learned during an additional quarter century of teaching and research. They updated the text to reflect the immense strides in physics during the same period and modernized and increased the number of exercises, for which the First Edition was famous. Enrichment boxes provide expanded coverage of intriguing topics. Sample problems encourage students to exercise their newfound power.
