Newer technologies like remote cameras and drones allow for聽minimally invasive data collection techniques in modern polar research. For example, scientists studying whales often rely on photographic identification of tail flukes, which function like unique fingerprints, allowing individuals to be tracked over time without physical capture.

Similar low-impact approaches are used in ice flow and climate research, including remote sensing, photography, and observational fieldwork of ice flows and glacier dynamics.

Physics & Astro Tea: The stability of the solar system over time /u/news/2026/03/06/physics-astro-tea-the-stability-of-the-solar-system-over-time/ Fri, 06 Mar 2026 14:04:39 +0000 /u/news/?p=1040952 Is the solar system stable?聽The planets follow generally predictable orbits around the sun, but small gravitational effects from other planets, moons and objects in the solar system subtly affect their motion. Alejandro C谩rdenas-Avenda帽o, assistant professor of physics at Wake Forest University, studies these affects to determine whether the solar system will remain stable over long periods of time.

In a recent talk at the Physics and Astro Tea,聽C谩rdenas-Avenda帽o shared the historical development of this problem, starting with Isaac Newton’s deterministic laws of motion and moving through the n-body problem, a generalized question about the long-term motions of gravitationally attracted objects. This problem famously has no analytical solution and must be done computationally.

So is the solar system stable? Will any planets suddenly be ejected? The best current answer is聽maybe, but not during our lifetime.

Physics & Astro Tea: AI inside tech companies /u/news/2026/02/25/physics-astro-tea-ai-inside-tech-companies/ Wed, 25 Feb 2026 18:51:26 +0000 /u/news/?p=1040204 In the past few decades, there has been a significant number of students across the country who major in physics, learn computer coding along the way and find themselves picking up programming and data analytics jobs after graduation. Megan Squire, former 黑料不打烊 Professor of Computer Science, was invited to the Physics & Astro Tea series to share her experiences as a computer scientist and researcher working in industry.

Squire is currently a threat intelligence researcher for F-Secure, a Finnish company specializing in cyber security and privacy. Under the theme of “everything is always changing all the time”, Squire said that in her workplace, AI tools are not optional; they are a “power up” that can increase individual productivity several times over.

However, those “AI tools are kinda problematic and also kinda good”, and there is a lot of gray area of what is ethical or even authentic. Squire encouraged students to find ways to protect themselves, their identities, and their value as they graduate and enter the job market.

Physics & Astro Tea: The sounds of sand /u/news/2026/02/17/physics-astro-tea-the-sounds-of-sand/ Tue, 17 Feb 2026 20:03:54 +0000 /u/news/?p=1039067 Beaches are known for the sound of the water, but sand can make some interesting sounds as well. Sometimes.

Associate Professor of Physics Martin Kamela spoke to a Physics & Astro Tea audience about the singing, whistling, squeaking and barking sounds that some sands can make. Researchers have found that, in order to make these sounds, sand granules need to be nearly spherical, small, and nearly uniform in size. These sounds seem to come from the friction between granules arranged in slip planes and are unrelated to other surface effects.

But sound is not the only trip up sand’s sleeve. Like some other granular materials, the empty volume between granules of sand will expand under shear deformation, explaining why sand seems to dry out when it is stepped on.

Open to all students, faculty and staff, this gathering is the perfect opportunity to connect with fellow physics aficionados in a relaxed and informal setting. Meetings take place in the third-floor lounge of Innovation Hall at 3:20 p.m. on Wednesdays.

Basu Zych became interested in astronomy at a young age at went to the University of California at Berkeley, but found herself burned out by the time she graduated. She spent time working at a telecommunications company before finding a job as a docent at a science museum. While at the museum, she was motivated to study for the physics subject GRE and apply to graduate school at Columbia University, where she graduated in 2009.

Basu-Zych left graduate school for a three-year post-doctoral position at NASA and another four-year stint on soft money, a type of external-grant funded position. Basu-Zych currently has a joint appointment with NASA-Goddard and the University of Maryland-Baltimore County, primarily working on聽multi-wavelength studies of starburst galaxies over the history of the universe. She collaborates with Associate Professor of Physics Chris Richardson and was able to spend several days at 黑料不打烊 in late October meeting with classes and research students.

Physics & Astro Tea: The magic numbers of germanium /u/news/2025/10/23/physics-astro-tea-the-magic-numbers-of-germanium/ Thu, 23 Oct 2025 13:12:41 +0000 /u/news/?p=1031378 Every element on the period table is defined by the number of protons in its nucleus, but the number of neutrons can vary widely. Elements with the same number of protons but different numbers of neutrons are called isotopes; some isotopes are more stable than others. Tyler Kowaleski (University of North Carolina – Chapel Hill) visited the Department of Physics and Astronomy to share the work he and his collaborators have been doing to figure out why this is.

Kowaleski is part of the Triangle Universities Nuclear Laboratory (TUNL), a partnership between UNC-Chapel Hill, Duke University, and North Carolina State University. Kowaleski and his colleagues use a particle accelerator to create gamma rays aimed at a variety of germanium isotopes. When hit with the gamma rays, germanium nuclei become excited and decay in a one-step “elastic” or two-step “inelastic” process. Emissions from the decay provide evidence about the structure of the nucleus and its stability.

Physics & Astro Tea: Diffusion in strained media /u/news/2025/10/08/physics-astro-tea-diffusion-in-strained-media/ Wed, 08 Oct 2025 12:59:47 +0000 /u/news/?p=1029835 “When cells are stretched or compressed, the movement of molecules inside them changes.” This is the impetus for the research Alexander Marshall has been doing at the University of North Carolina – Chapel Hill, where he is currently a graduate student. Marshall presented his work during the Physics & Astro Tea weekly event.

To study this movement, Marshall and his research group use a fast single particle tracking optical system to observe molecules in poroelastic gels, which are easily controllable analogs to cartilage.

In media where molecules are free to travel, they move randomly in all directions. In poroelastic gels, where molecules are contained in small volumes, molecules predictably move much less. However, Marshall and his group found that when the gel is deformed, molecular movement increases a small amount.
