ALT Two people sitting and talking together, while one has their laptop open on their lap.

ALT Two people are placing pins on a large, colorful map of the world. One person is focusing on a specific area of the map. They are both wearing coats and holding what appear to be travel documents or guides. The setting looks like a public event or a museum.

ALT A group of individuals stand in front of a large map backdrop with the APS logo. The map highlights a welcoming global community of APS members, with the text "Where is your home?" People are engaged in conversation and examining the map, some carrying backpacks.

ALT A series of three side-by-side photos capture Kelvin wave turbulence along an air-water vortex filament. A 40-centimeter-long vortex set against a black backdrop is bounded on the bottom by a red tube and on the top by an immersed gray annulus, where the vortex is forced by gentle random horizontal oscillations — generating interacting Kelvin waves that transport energy along the filament.

ALT A teacher works with four children gathered around a model in a classroom.

ALT Diagram showing a spinning black hole (labeled with spin a* and mass MBH) surrounded by a superradiant "SR cloud," emitting concentric wave-like ripples outward in all directions. The black hole sits at position r₀BH from the Galactic Center (marked "GC" with a red X), with its orbital velocity vφBH shown as a blue arrow. A red arrow points from the black hole toward a sun-and-Earth icon labeled with angular velocity ωφ₀. A second blue arrow near the icon shows its velocity relative to the black hole (v₀BH = −vBH₀), illustrating the relative motion used to model the emitted signal.

ALT A government webpage about student visas pulled up on a phone or tablet. The device is sitting on a keyboard that can be seen in the background.

ALT Mass-mass diagram showing constraints on the masses of two neutron stars in a binary system. Three colored regions derived from different relativistic measurements overlap in a small area, indicating that the measurements are consistent with general relativity. A gray region shows masses excluded by the system's mass function.

ALT A tweet from the American Physical Society (@APSphysics) that asks, "Physicists: What's something you’re surprisingly bad at?"

ALT Network diagram showing a chess position as a web of interactions. Black and white pieces are labeled with chess notation and connected by numerous colored lines representing attacks and defenses. The pieces are densely interconnected, with several major pieces and pawns clustered near the center and edges.

ALT A line of ants travels along a narrow branch with green grass in the background.

ALT Three students sitting on a cement bench in the city. They are discussing work with papers and textbooks on their laps.

ALT Solar panels installed among a lush green forest, illustrating the concept of renewable and sustainable energy generation.

ALT Plot showing the conditions under which dark matter halos in the early universe can form black hole seeds via direct collapse, plotted as initial density perturbation versus wavenumber. A pale diagonal band, labeled 'NQPBHs,' marks the parameter space between primordial black holes (top) and standard direct-collapse black holes (bottom), bounded by contours for virial temperature and collapse redshift.

ALT Teachers gather at a table and try out experiments from the PhysicsQuest kit.

ALT Three teachers sit at a desk; one teacher uses a device to measure the temperature of his palm while two other teachers look on.

ALT Microscopy video of starfish embryos moving in coordinated, swirling patterns, with red and blue arrows overlaid to show the direction of movement.

ALT Diagram illustrating bosonic and fermionic emission. Part (a) shows bosonic emission with multiple red arrows depicting photons emitted. Part (b) shows fermionic emission with some emissions crossed out, highlighting restrictions. Each part has energy levels labeled |e⟩ and |g⟩.
