When I prepared them, I had an inkling that these would be my last lectures at SMU; indeed, when my spouse accepted the position of Executive Director of SNOLAB in Canada, it was definitive: these had been the last lectures I would ever present to SMU underrgads. I hope you enjoy them. For the closing two days of PHYS 1303 in Spring 2022, students in the class suggested topics for a pair of special lectures. There were about 23 topics suggested. A Instant Runoff Voting procedure was then used so that the class could rank-vote the 23 proposed ideas, and the top idea was selected: Alien Life and the Probability of Life. Part 1 explores life as we (think) we know it and the possibility of finding similar conditions elsewhere in the galaxy that could have fostered a similar kind of biochemical life. This topics cuts across big bang nucleosynthesis, stellar nucleosynthesis, star and solar system formation, and the presence of rocky worlds in "habitable zones" around those stars.https://media.cooleysekula.net/static/streaming-playlists/hls/c535b649-aa1a-4f69-a10c-6ce6ac351803/fc1c246a-a528-4433-9032-2273d1ee032d-master.m3u8https://media.cooleysekula.net/videos/embed/qmraAUYjEsxMD7mUEEeeBr31280102023-10-21T22:00:59.166ZphysicslecturelifeYESLearning Physics (Hosted by Prof. Stephen Sekula)NOhttps://media.cooleysekula.net/w/tukYZUsNz2TG91zeMCVRyZhttps://media.cooleysekula.net/lazy-static/thumbnails/daa51b94-1ef3-48c6-8176-527fe1e21785.jpgSpecial Topics - Alien Life and the Probability of Life Part 2： Life as We Don’t Know ItPHYS 1303 Spring 2022 - Special Topics ASIDE: Parts 1 and 2 of this lecture constitute the last lectures I ever gave, during a regular term, to undergraduates at SMU.

Gravity, nuclear forces, fusion, and radiation. The balancing act of stars.The main sequence. How stars end: a star like the Sun, and stars heavier than the Sun. Neutron stars and black holes. The size of the Universe. Measuring cosmic distances (one lesson). The expansion history of the universe. A possible fate for the cosmos. The Higgs field, energy in "empty" space, and our incomplete knowledge of the universe. ERRATA: 1. Would a blast wave of neutrinos really convert the protons in your body to neutrons? Well, if they were anti-matter neutrinos, yes. But, I had this backward. In this case, the supernova makes a blast wave of neutrinos, which would convert neutrons to protons - even worse than the other way around, since this would severely destabilize the nuclei of atoms. But, would this happen to all protons in your body? No. This statement of mine was based on a conversation at lunch with some senior physicists when I was in college. Since then, better calculations have been done, and certainly at the location of Jupiter the neutrino blast wave would be LETHAL (in the sense of killing you with radiation damage), but not as extreme as I remembered.

Recap (Homage to Agents of Shield)This was a response to the famous incident in my introductory physics course where a learning assistant actually broke the handle of the sledgehammer we use during the "bed of nails/cinderblock" demonstration. We'd practiced it, but during class his swing went slightly amiss and this cracked the handle of the sledgehammer with no damage to the brick. We rescheduled the demo for next class. The semester theme was the Marvel Cinematic Universe, and all learning assistants chose superhero nicknames. Andrew's was "Thor" ... and we thought this was deeply ironic given that in Thor 3, Thor's hammer Mjolnier get's broken. I had to run out to Lowe's to get new hammers, which afterward we nicknamed "Stormbreaker" (Thor's second hammer in the MCU). So I made this little "recap" video, in the style of Agents of Shield, to start the next class.https://media.cooleysekula.net/static/streaming-playlists/hls/327b40ca-01c6-459c-8c5c-fcb558c59312/ededdce1-3fa9-4919-aba8-8a6573a997e5-master.m3u8https://media.cooleysekula.net/videos/embed/7ey3XsYMmdSfETSVwnK8By440132024-01-20T16:22:30.031ZteachingphysicsYESstephensekulaNOhttps://media.cooleysekula.net/w/1Yk8eMr3b9G3LSsiDHcDpphttps://media.cooleysekula.net/lazy-static/thumbnails/57e4d196-bb5d-402d-a467-265f1b8b93aa.jpgA Marvel-Style Pre-Title Roll for SMU PhysicsThis Marvel-style pre-title roll was something I made for fun as an opening to my MCU-themed semester of introductory physics.

Posted on August 13, 2013 “Going Up Alleys” Podcast Episode 4 – High-Performance Computing (Part 1) [A Metapodcast] On this episode of “Going Up Alleys,” Professor Thom Dunning speaks about the frontier of high-performance computing. This begins a multi-part series on interdisciplinary research – solving difficult problems by bringing together traditionally compartmentalized institutions, such as computing and humanities. This is also a meta-podcast! To make it, I dusted off some audio I once recorded for the “Mustang Physics Podcast,” but which never saw the light of day. Then I wrapped it up in slightly-less-dusty audio I once recorded to introduce it (which also never saw the light of day). Then I introduce the introduction. Very meta. Professor Thom Dunning is the Distinguished Chair for Research Excellence in Chemistry and a professor in the Department of Chemistry at the University of Illinois at Urbana-Champagne. Most importantly, he is the director of the Institute for Advanced Computing Applications and Technologies (IACAT) and the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign. The SMU Chemistry Department hosted Prof. Dunning for a seminar on October 19, 2011. They graciously invited students, researchers, and faculty from all science departments at SMU to participate in the seminar. Prof. Dunning spoke about many topics, including the state of high-performance computing (HPC), the technology behind recent advances and that needed for future advances, and the diverse scientific topics that demand more and more from HPC. This podcast begins a series on interdisciplinary themes.

Dirac, or just Paul Dirac, is one of the most brilliant physicists who has ever lived. He is also one of the most curious human beings ever to be a physicist, and that’s saying a lot in a field where curious personalities litter history.  This week, we take a look at two perspectives on Dirac: one from the introduction to the biography, “The Strangest Man,” and the other by a sports columnist who wrote about Dirac in the 1920s. NOTE: the biography makes clear that there is no strong evidence of the sports columnist actually writing the piece read in this podcast. More likely, it was a joke played by friends and colleagues of Dirac's for a party or a meeting, intended to remark with humour and respect on his aloof personality.

Beauty – or “symmetry” – is taken as a sign of success and simplicity in a mathematical model or physical theory. But what if that beauty was a threat to a complete understanding of nature? In this, the first part of a two-part series on symmetry and physical theory, we look at quantum field theory and symmetry. Show Notes • “Reality in the Shadows (or) What the Heck’s the Higgs?“. S.

A lot has happened since that episode. Here, in the conclusion of this two-part series on symmetry, I reflect on the realities we face in going back to school, in-person, in the middle of an exploding pandemic. I look at what happens when inadequate medical support meets human mortality, and the loss of genius that happens in the resulting mess.

The “Going Up Alleys” podcast is an ongoing conversation about curious avenues of investigation. The world is a strange and complicated place. In this irregular podcast, we’ll see how different people strive to make sense of it through creative and critical thinking. Except in this one, because I talk a lot. On July 4, 2012, the ATLAS and CMS Experiments announced the discovery of a new subatomic particle consistent with the long-predicted Higgs particle. I was able to be present in the CERN main amphitheater for the seminars, and in this episode I convey the story leading up to the announcement (and the announcement itself) using an audio diary. Please enjoy some of the sounds of the hours before the announcement, and of the announcement itself. There are no words to describe what it was like to not only know many of the people involved in this discovery, but to be present in the room when it happened. I would like to especially thank Aidan Randle-Conde and his mother, Carla Staton, for organizing the late night trip into CERN to secure a place in line . . . and for generally being awesome (and certainly excellent company during the long wait to get into the auditorium).

(Fall 2021)After a year of online learning during the worst phase of the SAR-CoV-2 COVID-19 pandemic, students and faculty came back together in the classroom for active learning. My Honors Physics section always spends its second period in a competition between the newly formed teams. The teams compete in a "Jeopardy!"-style quiz game with categories related to physics and to their theme for the semester. The semester's theme was "The Physics of Cartoons". The energy in my classes this semester was incredible as people were thrilled to be back in-person and engaged socially and intellectually once more. This game night was a joy and I am excited to share an example of this here. This class was so large, I had to run the competition in two rounds in order to keep the number of competing teams to 3-4 per round. So half the teams compete in the first 20 minutes (or so) and the second half in the remaining time. If anyone wants the code for this game, it's written entirely in Javascript, CSS, and HTML5. I'd be happy to share.

I visited SURF during the week of March 10th, 2025, to give a public lecture. The trip marked the end of the underground laboratory tour. You will see people loaded on the cage and the beginning of the ascent. The trip takes about 10 minutes. You can see the wood frame of the Yates mineshaft. The wood is kept intentionally wet, which is why it appears to be raining around the cage, to prevent dry rot.https://media.cooleysekula.net/static/streaming-playlists/hls/eec278b8-1ac9-4260-be91-9d75b7d04f13/845d76d4-c31f-4b00-a17e-e76c342d5aa2-master.m3u8https://media.cooleysekula.net/videos/embed/vu21NSRhqU23QcsPjG6rb428532025-03-30T15:07:07.176ZminesurfscienceindustryYESstephensekulaNOhttps://media.cooleysekula.net/w/rENYCoCVMqDkzRqfFS4WRzhttps://media.cooleysekula.net/lazy-static/thumbnails/b896809b-30fb-4992-b538-3052f67c1d3b.jpgSanford Underground Research Facility: Electric Tram Ride from the Yates to the Ross ShaftA five minute journey by electric tram from the Yates shaft region of the underground laboratory (the "Davis Campus") to the Ross shaft region of the lab (the "Ross Campus"). https://media.cooleysekula.net/static/streaming-playlists/hls/cfdfae11-8252-4331-8bbc-880235592a4b/791b6bc3-7896-4b18-bbdf-299629589e5c-master.m3u8https://media.cooleysekula.net/videos/embed/rENYCoCVMqDkzRqfFS4WRz3290132025-03-30T15:33:46.987Zsurftrainunderground sciencescienceYESstephensekulaNOhttps://media.cooleysekula.net/w/pkrhnpvN9mh28Vbfc3f7VBhttps://media.cooleysekula.net/lazy-static/thumbnails/875521dd-34b2-477c-8ff1-065dab88eecb.jpgSanford Underground Research Facilty: looking into the DUNE CavernDUNE, the Deep Underground Neutrino Experiment, will eventually be sited in this (and another twin) large cavern. These caverns form the Long Baseline Neutrino Facility (LBNF). DUNE is a massive project led by the Fermi National Accelerator Laboratory to construct the world's largest particle detector. Once complete, it will observe neutrinos produced in an intense subatomic particle beam sourced at Fermilab, shot through the crust of the Earth, and then emerging into these caverns. Only neutrinos survive the journey. These detectors will probe the fundamental structure of neutrinos and provide additional capabilities, such as cosmic neutrino detection. Each cavern is 1.5 American Football fields in length (about 130m) and 800,000 tons of rock was removed to make these caverns. That rock was moved to another site at the laboratory to ensure that it remains part of the land from which it was removed.https://media.cooleysekula.net/static/streaming-playlists/hls/bcf8e6ca-f892-4307-be86-437c8b4b80ad/42f1cd7d-454b-47e0-9b38-1e0231181cbd-master.m3u8https://media.cooleysekula.net/videos/embed/pkrhnpvN9mh28Vbfc3f7VB14092025-03-30T15:16:12.112ZdunelbnffermilabsciencesurfYESstephensekulaNOhttps://media.cooleysekula.net/w/gty4jmBuw6NY2B4VYomfvBhttps://media.cooleysekula.net/lazy-static/thumbnails/61743010-de56-4e75-966f-07e7ef68fb13.jpgOur Lopsided Universe: The Matter with Antimatter (SLAC Summer Lecture Series, 2004)My first public lecture ever, delivered in the Panofsky Auditorium of the Stanford Linear Accelerator Center (renamed the SLAC National Accelerator Laboratory in 2008). I was a young postdoctoral researcher at the time and was tasked with delivering a lecture on the "matter/antimatter problem" ... the fact that the universe is matter-dominated, despite all evidence suggesting equal parts matter and anti-matter were present after the beginning of time. I framed this problem in the context of work ongoing at the BaBar and Belle Experiments to map the amount of favouritism for matter over antimatter in quark-based systems. This lecture was given on June 29, 2004.

In my introductory physics courses, students were often offered the chance to suggest topics not covered in the course but that can be explored through introductory physics. In this term, my pre-health students selected two topics: the physics of the movie "Interstellar" and the physics of time. These went very nicely together, so I made a single special topics lecture on both. Any footage from the film used in this was purely for the purpose of making an educational point, and the lecture doesn't make sense without those scenes, stills, and clips.https://media.cooleysekula.net/static/streaming-playlists/hls/a2c241b2-a6a5-44bc-9b28-4afce66e99a2/a542f0a7-c467-4be9-8d99-a5ee5775f807-master.m3u8https://media.cooleysekula.net/videos/embed/m6GbGFyZm96bqQWzkVeHuf49885122025-08-30T16:19:10.572Zinterstellar movietimespecial topicphysicsYESLearning Physics (Hosted by Prof. Stephen Sekula)NOhttps://media.cooleysekula.net/w/jdCi5z9SSBMM6s9nYnA5tShttps://media.cooleysekula.net/lazy-static/thumbnails/d41e1d28-aee3-4f5c-9391-87fbd1439de1.jpgTopics in Quantum Spin - Lecture 2: Orbital Angular MomentumExpectation value and Variance; the non-relativistic Schroedinger Wave equation; orbital angular momentum. https://media.cooleysekula.net/static/streaming-playlists/hls/9387c9d3-132e-45e8-bcbc-e830a49060c0/e02d59cd-446e-4016-ad48-cddfe9026cbc-master.m3u8https://media.cooleysekula.net/videos/embed/jdCi5z9SSBMM6s9nYnA5tS6322012025-08-30T19:52:42.572Zlinear algebraquantum mechanicsquantum spinangular momentumschroedinger wave equationYESLearning Physics (Hosted by Prof. Stephen Sekula)NOhttps://media.cooleysekula.net/w/tWMuQ5orXqZf3BF9agDey2https://media.cooleysekula.net/lazy-static/thumbnails/17b1c60c-fa2d-4f8b-9f48-33ac099be7cd.jpgSnowball, when he was a kittenThis is our now eldest cat, Snowball, shortly after we rescued him from a shelter in Allen, TX, USA.

Jodi Cooley, wields the hammer in this fantastic "bed of nails" demonstration. She was really going for blood when she swung the hammer, demonstrating to everyone how serious she was about smashing through the cinder block ... and at the same time, demonstrating the relative safety of this example. A person lies down on a 3000-nail "bed of nails". The force per nail is well below the breaking point of skin or clothing for a ~95kg male. A second, smaller bed of nails is placed on the chest. This supports an upright cinder block. A sledge hammer is then swung at the cinder block. Normally, we recommend the hammer wielder let gravity do the work after raising the hammer to the top of the swing. Jodi went for broke, and helped gravity. It was magnificent. The student's reaction is priceless. The person on the bed of nails should wear leather gloves (prevents splinters when handling the beds) and a face shield (protects from flying bits of cinder block, which is actually the most dangerous part of the demo). The force of the swing is absorbed in breaking the chemical bonds of the cinder block material, absorbing most of the force. The person in the bed of nails feel a slight pressure, but other than that it is safe.https://media.cooleysekula.net/static/streaming-playlists/hls/4fd74492-d957-4f0f-a045-7cd72367513a/c8f3d243-d527-4237-93c5-e0d48fffc39c-master.m3u8https://media.cooleysekula.net/videos/embed/aRPZs3f8MsbzhHYhqL2qFu100142025-12-24T12:29:06.379Zphysicshammercinder blockbed of nailsdemonstrationYESstephensekulaNOhttps://media.cooleysekula.net/w/e1r8VJc95rQnpRyGfHdTaghttps://media.cooleysekula.net/lazy-static/thumbnails/ce892088-9015-48e0-a930-5ad53a65b831.jpgDemonstrating Problem Solving: Damped and Driven OscillationsLearning to setup and solve a problem involving a loss of energy from a system capable of simple harmonic oscillation.https://media.cooleysekula.net/static/streaming-playlists/hls/69564b29-35ff-44bf-acb0-280fbe2e9575/52b0a490-3a1f-4c51-9079-02a357a455b4-master.m3u8https://media.cooleysekula.net/videos/embed/e1r8VJc95rQnpRyGfHdTag2051012025-12-24T13:32:07.801Zphysicsoscillatory motiondamped oscillationsenergyproblem solvingYESLearning Physics (Hosted by Prof. Stephen Sekula)NOhttps://media.cooleysekula.net/w/6R3jzgzmZUB8w7cNVzaZ2chttps://media.cooleysekula.net/lazy-static/thumbnails/1ccc06e0-3495-46ae-b50a-b12a3cef911d.jpgDemonstrating Problem Solving: Simple Harmonic OscillationExamining the mathematical description of simple harmonic oscillatory motion.
