An unexpected duet of heavyweights!
Last year, CMS announced the observation of a top quark antiquark bound state, which could be toponium – this has now been confirmed by the @atlasexperiment.bsky.social! Roberto Salerno, a physics coordinator of CMS, explains. Read more: home.cern/news/press-r...

The Democrats on the House Science Committee have set up a website to collect stories from fired federal employees, anonymously if desired. Please amplify. (This helps the lawyers establish standing for bringing legal cases against the administration!)

i don’t think we realize just how MASSIVE things in space are

does anyone else think that it’s crazy that we live in an era where we can watch a sunset on ANOTHER planet?

Let’s play around with cosmic distances shall we? Because I don’t think the human brain can actually understand it. But I’m gonna use rice, and say 1 grain = 10,000 miles (~16,000 km).

That means the circumference of Earth is just under two and a half grains. These contain all our lives 🧪🔭 (1/n)

Physicist Polykarp Kusch was born #OTD in 1911. His measurements of the magnetic moment of the electron revealed that its value disagrees with naive predictions by a tiny amount — about 0.1%.

Quantum Electrodynamics offers a marvelous explanation of this minuscule discrepancy. 🧪 ⚛️

This is one of my most favourite photos of Saturn.

Diversity, equity, and inclusion are all good things. They don’t happen automatically, we have to actively work to bring them about. Shout it from the rooftops.

2025 is the International Year of Quantum Science and Technology #IYQ25. To celebrate, @physicsmagazine.bsky.social is republishing archival stories on the history of quantum physics. The 1st recounts Robert Millikan’s measurement of Planck’s constant. ⚛️ 🧪

Quantum Milestones, 1916: Millikan’s Measurement of Planck’s Constant
The experiment provided further proof of the reality of photons, yet Millikan didn’t accept their existence until later in his career.

Yes, I've run into this. These folks start with the conclusion - "only 2 sexes" - and work backwards to find biological justification. It's hard! They end up with gamete size. But that is so far removed from relevant human-scale aspects of gender so as to be irrelevant, which they then ignore.
carlbergstrom.com Carl T. Bergstrom @carlbergstrom.com · Jan 21
I think what’s going on here that these people are trying to find some true binary relating to biological sex. Genital morphology won’t do it. Sex chromosomes don’t do it. So they’ve retreated to gamete size. I think the use of large and small cell is also a hedge in this direction, not prudishness.
Excerpt from Trump executive order: (d) "Female" means a person belonging, at conception, to the sex that produces the large reproductive cell. (e) "Male" means a person belonging, at conception, to the sex that produces the small reproductive cell.

The Tarantula Nebula, also known as NGC 2070, is a star-forming region located in the Large Magellanic Cloud. This image, captured by the James Webb Space Telescope's Near-Infrared Camera (NIRCam), showcases the nebula's intricate structure and vibrant colors. Red hues indicate the presence of hot, ionized hydrogen gas, while blue areas reveal cooler dust and gas.

The value of g, the acceleration of an object under gravity at the Earth’s surface (9.81 m/s^2) is very close to pi^2 = 9.87. It’s a better approximation than g = 10 m/s^2, and this is no accident…

Another brilliant and important woman in physics who is not as well known as she deserves to be.

Mathematical physicist Cécile DeWitt-Morette was born #OTD in 1922. She made foundational contributions to Feynman functional integrals, organized the first American conference on general relativity (important for gravitational waves), and started the Les Houches Summer School. 🧪 ⚛️ 👩‍🔬 (1/n)

It's #TransgenderAwarenessWeek and I want to re-up this really wonderful and moving essay by SciCommer Kade Huckstep.

We posted some quotes from the essay as tiles below, but def. take some time to read this piece.

Kade Huckstep wrote an essay for #TDoV that is well worth the read.

Because supporting and elevating trans & gender-diverse voices goes well beyond a single day.

Celebrating Trans People by bringing Visibility to their Resilience By Kade Huckstep (they/he). Neuroscience PhD Candidate. Science Communicator To be trans is not to have been born in the “wrong body”. To be trans is to know there are infinite ways to exist in a body, and its infinite capacity to evolve. - Kade Huckstep (they/he). Neuroscientist I trust trans people to believe me when I say: transitioning has been the hardest thing I’ve ever done in my life, but also the best. This TDOV, here is what I want from the cis folk in my life: Hold space for our grief. And take the time to really see us. See us for more than just our transness. See us for the full, messy, complex, imperfect, multidimensional, and ever-evolving beings we are. Help us feel visible.

Quantum field theories (QFTs) are the most successful theories in the history of physics.

Unfortunately the success and implications of QFTs are less known outside of physics (compared to e.g. string theory or general relativity).

star clusters are so beautiful ✨
Bright blue stars are in a cluster at the center of the image. They are surrounded by a shell of brownish and burnt orange dust and gas. The shell has ridges that reach towards the stars like teeth. A number of more distant galaxies also appear in the background. A grouping of large, glowing, and purplish stars dominate the image’s center. Dark ridges of gas and dust are visible around them, with more background stars crowding the view. Several bright-white, bluish, and orange stars shine with diffraction spikes, interspersed throughout dark dust. Particularly dark regions of gas and dust are seen near the lower left. A dense cluster of bright stars. The core of the cluster is to the left and has a distinct group of blue stars. Surrounding the core are a multitude of stars in warmer colors. These stars are very numerous near the core and become more sparse, as well as more small and distant, out to the sides of the image. A few larger stars also stand in the foreground near the edges of the image.

Every spec of light here is a distant galaxy, containing billions, if not trillions, of stars.
There are over 45,000 galaxies here.
🔭 🧪
This infrared image shows a portion of an area of the sky known as GOODS-South, which has been well studied by the NASA/ESA Hubble Space Telescope and other observatories. More than 45,000 galaxies are visible here. Using these and other data, the JADES team has discovered hundreds of galaxies that existed when the Universe was less than 600 million years old. The sheer number of these galaxies was far beyond predictions from observations made before Webb’s launch. The team also has identified galaxies that existed during a time known as the Epoch of Reionization, when the Universe underwent a transformation from opaque to transparent. Many of these galaxies shown unusually strong emission line signatures due to the creation of multitudes of hot, massive stars.
