Belgian chemist, industrialist and philanthropist Ernest Solvay was born #OTD in 1838.
He is best known for his pioneering work in the chemical industry and for the establishment of the Solvay process for the manufacture of soda ash (sodium carbonate). In 1911, he began a series of important conferences in physics, known as the Solvay Conferences, whose participants included Max Planck, Ernest Rutherford, Maria Skłodowska-Curie, Henri Poincaré, and Albert Einstein.

⚛️ The Quest to Map the Inside of the Proton | WIRED
「 Physicists have begun to explore the proton as if it were a subatomic planet. Cutaway maps display newfound details of the particle’s interior. The proton’s core features pressures more intense than in any other known form of matter. Halfway to the surface, clashing vortices of force push against each other. And the “planet” as a whole is smaller than previous experiments had suggested 」
April 14 has been designated World Quantum Day in honour of Planck’s Constant which can be rounded to h~ 4.14×10−15 eV·s (and some folks write April 14 as 4/14*). Planck’s constant comes up a lot in quantum mechanics; for instance a photon’s energy is h times its frequency). So I thought I would share Feynman Bauhaus.

“In an alternate universe, you were never born. Parallel universes don’t care. Everyone talks about how they are different, but there are an infinite number of universes identical to this one. No one has, yet, proven that the number holds any significance.”
When I made the figure below I used LaTeX, powerpoint and then LaTeX again. Having learned some TikZ I now think I could draw it using TikZ, but apparently I'm too lazy...
After watching it, I know why this thumbnail talks to me that much.
She talks about her story in physics research academia, she talked about my future in biology research academia.
Every point she makes in this video, I share them and I’ve been repeating it for years.
I love science, but I can’t do honest science in this system. It’s morally made to make money, and money is the sole reason why people write papers, not truth and discovery.
I really don’t know what I can do in my life with that much passion in a field but no way to practice it.

#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!
Dear Ham friends,
Weather permitting, on April 28. around 10 to 12 UTC, a student of mine will launch a weather balloon carrying a WSPR beacon on 20m in order to analyze the worldwide propagation as a function of altitude, based on WSPR report data.
It will probably broadcast our club call DL0WH or my own.
We'd be delighted if you turn on your receiver and see if you can spot us. Launch QTH will be Weinheim DL0WH.
