What's next for particle #physics after the Large Hadron Collider at #CERN? A conference in London earlier this week debated several possibilities for the so-called Future Circular Collider (we're sure they'll come up with a better name eventually).
Sadly @PlotAstro and @PlotPhysics haven't (I hope yet) appeared here on Mastodon. But, as was recently pointed out by a colleague, we all already know the greatest physics plot in a paper of all time. It's Fig. 1 from https://arxiv.org/abs/1909.11090 .
Fig. 1 is an exact 1:1 scale image of a 5 Earth mass black hole.**
Henri Becquerel discovers radioactive decay #OTD in 1896.
Becquerel layered photographic plates with coins or other objects then wrapped this in thick black paper, placed phosphorescent materials on top, placed these in bright sun light for several hours. Despite the bad weather (he left his layered plates in a dark cabinet) he proceeded to develop the plates: the object shadows were just as distinct when left in the dark as when exposed to sunlight.
German physicist Wilhelm Röntgen died #OTD in 1923.
Nobel Prize in Physics won for his discovery of the remarkable rays subsequently named after him. In November 8, 1895, he found that, if the discharge tube is enclosed in a sealed, thick black carton to exclude all light, and if he worked in a dark room, a paper plate covered on one side with barium platinocyanide placed in the path of the rays became fluorescent even when it was as far as two metres from the discharge tube.

A quantum simple pendulum.
The pendulum position is spread out, with opacity here being proportional to the probability that the pendulum is at that position at a given time. The average position of the quantum dynamics is the same as the classical pendulum dynamics (Ehrenfest theorem).
Technicalities: I used the Crank-Nicholson method to evolve the system in time. This is a 1D problem, and the only variable I considered was the angle, with the initial state being a Gaussian.
As a fluid dynamicist, a small mountain brook on a sunny day can be endlessly entertaining.
The shape of the water's surface is determined mostly the fluid's momentum and surface tension. You can see in this 1/2000 secs exposure the whimsical surface's shape, bubbles and capillary waves.
#Introduction
Hi! I've been on mastodon since summer 2023, but this is my brand new account. I'm interested in #FreeOpenSource#privacy respecting software, #OpenAccess science, and overall community driven spaces. I study #physics, I'm a beginner-level programmer, and would like to start contributing to some #foss#floss projects or sharing my own code. I thought I'd join floss.social to be in a community of like-minded people. I also like #flowers. That's all for now. Have a nice day!
This spatial representation of the subject, dating from 1939, defines itself as Being a map of physics, containing a brief historical outline of the subject as will be of interest to physicists, students, laymen at large; Also giving a description of the land of physics as seen by the daring sould who venture there. via @bigthink
I'm your classic cat loving, #Linux using, 20-something-year-old student who grew up with effectively unsupervised internet access. After far too much overthinking and lurking, I've decided to finally make an account and say "hi" (hi :ablobcatattention:).
Not entirely sure what I'll post, but hopefully some before/after posts on basic tasks for my own accountability ( #accountabilibuddies ?). There's also a pretty good chance I'll post some pictures/updates for a #Flatland simulator I'm building with Matter.js. It can import very basic constructions from #Geogebra, displays 1D and 2D perspectives, handles reflection and refraction, has a basic #Lua API, and a very incomplete model of electromagnetism that is constantly challenging me (it's getting there, but right now the #physics of conductors are giving me headaches. My understanding is that the entire surface of an ideal conductor is an equipotential, but I don't understand what the potential value should actually be when there's multiple nearby charges. I get the feeling I'll need to completely change what I'm doing to handle anything with a permittivity other than 1).
Well… That got longer than intended. I'm off to go handle some laundry now.
Congratulations to the entire @VirginAtlantic team consisting of researchers from several universities and private companies for successfully completing the 1st transatlantic flight from London to NY in a commercial Boeing 787 using non fossil fuel made from waste fats.
The researchers will be making their exact process opensource for all.
French mathematician and physicist Henri Poincaré was born #OTD in 1854.
He is considered one of the founders of the field of topology. He was among the first to present the Lorentz transformations, part of the groundwork for Albert Einstein’s theory of special relativity. Poincaré also studied the behavior of planetary orbits and contributed to the three-body problem in celestial mechanics, exploring the stability and motion of celestial bodies.
Using a spectrograph that he developed, he and his student K. S. Krishnan discovered that when light traverses a transparent material, the deflected light changes its wavelength and frequency. This phenomenon, a hitherto unknown type of scattering of light, was subsequently termed the Raman effect or Raman scattering. Raman received the 1930 Nobel Prize in Physics. via @wikipedia
American physicist Robert J. Van de Graaff died #OTD in 1967.
His research interests included electrostatic generators and nuclear research. He invented the Van de Graaff generator, an apparatus designed to supply high voltage to accelerate subatomic particles to very high velocities for the bombardment and study of atomic nuclei.
