How does light bend at the interface between two media, and what determines the angle?
With Bending Light, students can explore light between two media of different indices of refraction and play with different prisms(shapes and materials) https://phet.colorado.edu/en/simulations/bending-light/ #Optics #Prisms #physics

What’s the point of exploring the Universe?
#AskEthan
With so much going on in the world and so many problems to solve, why should we be investing in exploring the Universe?
We must always remember.

“500,000-km Solar Prominence Eruption”
It’s difficult at times to fathom the scale and power of fluid dynamics beyond our day-to-day lives. Here, twists of the Sun‘s magnetic field propel a jet of plasma more than 500,000 kilometers out from its surface in an enormous solar prominence eruption. To give you a sense of scale for this random solar burp, that’s bigger than ten times the distance to satellites in geostationary orbit. (Image credit: P. Chou; via Colossal)

(27 Nov) Did a NASA telescope really ’see’ dark matter? Strange gamma-rays spark bold claims, but scientists urge caution
A new study says observations from the NASA Fermi space telescope suggest a halo of dark matter around the center of our galaxy, but more information is needed to confirm the result.

🧑🎓 PhD positions in “Gravity at the Extreme: from Theory to Observation” at the @mpi_grav in Potsdam 🇩🇪
ℹ️ https://www.aei.mpg.de/1334890/phd-positions-imprs-2026
📅 deadline for full consideration: 19 Dec 2025
We announce opening of several PhD positions at the International Max Planck Research School (IMPRS) “Gravity at the Extreme: from Theory to Observation”.
We are particularly interested in hiring creative, proactive and motivated candidates who flourish at working in a vibrant, interdisciplinary and synergistic group.
Successful candidates will join one of the scientific departments, either the “Astrophysical and Cosmological Relativity” or the “Computational Relativistic Astrophysics” department.

WOW. This was an outstanding episode of Veritasium on the Power Law probability distributions (i.e. probability distributions described by an *exponential* relationship between the variables). I never realized these types of probability distributions are so common, and that they behave in such similar ways to each other.
Even more bizarrely to me, there appear to be many systems in nature that *spontaneously* organize themselves in a way to exhibit Power Law probability distributions. In fact, I suspect that “black swan” events are possibly a symptom of mistakenly perceiving a Power Law distribution phenomenon as one exhibiting a Normal or even Log-Normal distribution.
