I awoke to the buzzing of my wristwatch. It was 4:30am. The telescope and all its accessories were already in the car. I only needed to get out of bed and dress myself. Jupiter waited. In the night sky above Allen, I was sure it was clear and that Jupiter […]

I am in the middle of spending two weeks at CERN. Week 1 just ended, and Week 2 has just begun. I reflect on ducking away from SMU for two weeks of research at CERN during a crucial time for new members of our SMU ATLAS group. The first week […]
I thought it might be nice to reflect on the physics that I am most interested in understanding during this second run of the Large Hadron Collider (LHC). In this post, I will discuss the Higgs boson, its expected interaction with bottom quarks, and how we have come to understand […]
I just spent two weeks at CERN. Due to limited travel funds this year, I had to keep my summer time here limited to save money for other trips and my research leave in the spring of 2017. Nonetheless, this was an incredibly productive pair of weeks. I’ll reflect a […]
This summer began, for me, with a little bit of travel. The first part was for relaxation; Jodi, her oldest younger sister, and I went to Paris for a week. After that, we headed to the conference “Rencontres de Blois” for which Jodi is an organizer. In these brief “field […]
100 years ago, Albert Einstein published what is considered the foundational work of his theory of “General Relativity,” a scientific theory of space and time. Tomorrow, two large experiments and collaborations – LIGO and VIRGO – will present the status of their searches for one of the last undiscovered predictions […]
The following is the underlying text I wrote as the basis for a talk at the TEDxSMU-sponsored event, “Loyd on the Lawn.” It was held at Loyd Residential Commons at SMU, where I was invited to give a short (~10-minute) talk last Sunday night. Enjoy!

Yesterday, the 2015 Nobel Prize in Physics was awarded jointly to two physicists – Takaaki Kajita and Arthur B. McDonald – who made leading contributions to the discovery that neutrinos, very difficult-to-detect subatomic particles, can actually change from one kind to another kind spontaneously. This is called “neutrino oscillation” or […]
For the second time, I will be attending the Rencontres de Blois, a yearly conference that represents a convergence (perhaps even a conversation) between cosmology, astronomy, astrophysics, and particle physics. Held in the Chateau de Blois, a castle perched above the Loire River in Blois, France, this conference will bring […]
I am Stephen Sekula, an Assistant Professor of Physics at SMU conducting research on the ATLAS Experiment. These comments will be my own, and I will try to take a broad view. Let me begin by thanking the members of the Panel for this opportunity to speak, and let me […]
Editorial Note (9/1/13): The program “Marketplace” recently looked into Mr. Mills’ claim. They found it to be nonsense. See: http://www.marketplace.org/topics/sustainability/no-your-phone-doesnt-use-much-electricity-refrigerator. I like that they put the answer right in their headline: NO. Editorial Note (8/23/13): since originally posting the article, a commenter (“Jay”) pointed out that the number I pulled from […]
