Physics and Astronomy Professor Ken Wharton and his recently graduated bachelor's degree student Raylor Liu here at SJSU have a new paper out, published in Foundations of Physics, which challenges the necessity of Einstein's famously coined requirement of "spooky action at a distance" in quantum mechanics.
In their paper, entitled "Entanglement and the Path Integral" [see Found. Phys. 53, 23 (2023)], Wharton and Liu have shown how to analyze complicated quantum entanglement scenarios with a simple "sum over histories" method, similar to one pioneered by Dr. Richard Feynman. Liu devised a way to extend Feynman's methods to scenarios where two particles are jointly measured, and then showed that a very different calculation still leads to the conventional results. This paper shows that there are alternate ways to make sense of quantum entanglement, and that some of the strange non-local aspects of the conventional approach are not strictly required to match experiments.
Physics and Astronomy Professor Thomas Madura is among the co-authors of a manuscript published in the journal Nature Astronomy that reveals a spectacular set of nested dust shells surrounding the carbon-rich Wolf–Rayet binary star system WR 140. The results were were acquired using the mid-infrared measuring capabilities of the recently commissioned James Webb Space Telescope, and they indicate that dust-forming binary systems of this sort can enrich the interstellar medium with organic compounds and carbonaceous dust.
Additional information on the discovery, including a popular summary of the result and a public outreach video, is available directly from NASA here.
Physics and Astronomy Professor Alejandro Garcia's new book Essentials of Modern Thermodynamics is newly published and available for purchase on Amazon.
According to Garcia, this book "puts the dynamics back into thermodynamics." While classical thermodynamics focuses on systems at equilibrium, modern thermodynamics emphasizes irreversible processes in systems out of equilibrium. The book is not designed as a course textbook but it should help you understand thermodynamics, in or out of school.
Essentials of Modern Thermodynamics is the latest in Garcia's long list of acclaimed contributions to the physics community. Garcia has published over 70 journal articles in the field of microscopic fluid mechanics, has organized numerous international workshops in this field, and in addition this newest publication he is the author of the popular textbook, Numerical Methods for Physics.
On July 12, NASA’s James Webb Space Telescope (JWST) released its first full-color scientific images and spectroscopic data, marking what NASA describes as “the dawn of a new era of astronomy.” According to NASA, “the Webb is the world’s premier space science observatory,” geared at solving the “mysteries in our solar system,” and is an international program conducted in partnership between NASA, the European Space Agency (ESA) and the Canadian Space Agency (CSA).
In connection with the release, Prof. Thomas Madura shared his thoughts on the photo release with the SJSU NewsCenter, as a leading astrophysicist in SJSU's Department of Physics and Astronomy, and as a member of member of NASA’s Early Release Science (ERS) program assigned to observing JWST images to investigate space dust.

In a study published this month in Physical Review Physics Education Research, SJSU Prof. Cassandra Paul and her co-author David Webb from UC Davis report on hidden inequities in one of the most commonly used grade scales in higher education – the percent scale (in which a score of 90%-100% is an "A", 80%-90% is a "B", and so on and so forth until the lowest grade of an "F" is assigned with a score of 0-60%).
Paul and Webb conducted a quantitative analysis of 95 introductory physics classes including more than 16,000 students, and then compared courses where students are graded using the percent grading scale to those courses where students are graded using the 4.0 grading scale (where an “A” is 4 points, a “B” is 3 points, a “C” is 2 points, a “D” is 1 point, and an “F” is zero points). While all students graded using the percent scale on average suffer a penalty due to the harsh impact of zeros and low partial credit, students belonging to demographic groups defined as those underrepresented in physics suffer an additional penalty that is not explained by their understanding of physics.
Paul and Webb hypothesize based on prior work that one reason behind this inequity is that the test-taking approaches used by students differ by demographic group. They emphasize that a solution to this inequity is not to teach appropriate test taking strategies, but rather to implement alternative grading methods to better measure the understanding of their students.
The California State University’s Office of the Chancellor has awarded a $222,000 CSU CREATE Award (Creating Responsive, Equitable, Active Teaching and Engagement Award) to four members of San José State University’s faculty, including Profs. Cassandra Paul and Gina Quan in the Department of Physics and Astronomy. SJSU’s award is the largest bestowed by the CSU of the five winning proposals, which ranged from $48,000 to $222,000. The other two members of the winning proposal team are Resa Kelly, professor of chemistry and science education; and Jennifer Avena, assistant professor of biological sciences. The team's principle investigator is Prof. Paul.
The inaugural CSU CREATE Award program is designed to accelerate momentum toward Graduation Initiative 2025 goals by creating opportunities for faculty to lead innovative projects. The SJSU faculty, along with Kim Coble, physics and astronomy professor at San Francisco State University; and Laura Rios, assistant professor of physics at California Polytechnic State University, San Luis Obispo; received the award for their proposal “Agents of Change: Faculty-Learning Assistant Partnerships Supporting Active, Engaging, Equitable Learning Environments.”

The Department is proud to announce the student winners of the 2022 academic awards competition. Winners of the awards are (from left) Sidney Johnson and Tommy Wen Chin, who have been awarded the Undergraduate Award for Academic Excellence; Shivam Kamboj, who has been awarded the Outstanding Teaching Assistant Award; Autumn Galinski, who has been awarded the Richard & Angela Craig Scholarship; and Kai Sian Hu (not pictured), who has won the Graduate Award for Academic Excellence.
The Undergraduate Award for Academic Excellence has been jointly awarded to Sidney Johnson and Tommy Wen Chin. Sidney has an excellent academic record, served the Department as Physics Club President, and has just submitted a first-author publication (to The Physics Teacher) summarizing student and faculty reflections on the Physics & Astronoy Student Reading Society (PhASRS), an online journal club that Sidney was heavily involved with in the summer of 2020. She has continually improved her academic performance over the course of her undergraduate career and has shown immense growth during her time as part of the Department. She is outspoken in class, and is committed to the betterment of the Department and building a strong community through (for example) her involvement in the LA program and in the Physics Club. Sidney is bound for the University of Oklahoma's PhD program in physics in the Fall of 2023. Tommy Wen Chin pulled off nearly straight A's here at SJSU, participated in almost every academic endeavor possible related to physics and beyond, is Treasurer of the Physics Club, is a tutor with CoSAC, is an unofficial tutor to his peers in basically every class that he takes, has been a significant contributor to the content of the Physics 52 manual, and is on-track to submit a first-author paper in the near future to Physical Review B about silicon-vacancy centers in diamond. Tommy has also participated in multiple summer research experiences and contributed posters and presentations at several meetings, mostly notably, a contributed in-person talk on silicon-vacancy centers at the 2022 APS March Meeting. Tommy is bound for Penn State's PhD program in physics in the Fall.
The Outstanding Teaching Assistant Award has been given to Shivam Kamboj. Shivam has a clear passion for teaching. Since joining the Department as a TA in Fall 2020, he has shown remarkable growth as a physics teaching assistant. During his time at SJSU Shivam has taught the Physics 2A lab multiple times, including teaching three sections in Spring 2022. Nearly 100 undergraduate students have interacted with him over the course of his teaching career at SJSU. Shivam exemplifies excellent teaching by providing students with empathy and encouragement, and is flexible in working with students to meet their goals in the course. Shivam received endorsements of his teaching excellence from the other members of the Physics 2A teaching team. Shivam will begin a PhD program in Physics at UC Merced in the Fall, where he expects to continue his teaching journey.
The Richard & Angela Craig Scholarship has been awarded to Autumn Galinski. Autumn will be a senior at SJSU in the fall of 2022, and has already left her mark in several areas. Her instructors have described her as an extraordinary student who is prepared for class and active during lessons. Her research efforts in Dr. Aaron Romanosky’s lab has resulted in a poster presentation, a successful student grant, and entrance to an REU at the University of Rochester this summer where she is working on a cosmology project. She has also worked on campus as a peer educator providing both supplementary instruction to students and serving as their peer mentor. She plans to apply for astrophysics and astroparticle physics PhD programs this upcoming fall. We are excited to see what she does next!
