me and @klara_hutkova yesterday

Yeah you have New Year’s resolutions but do you have

If you touch two CLEAN blocks of the same metal together in space, they weld! Atoms in solid metals move a bit. Touch two clean surfaces together, and the atoms can't tell they're in different blocks so they become one group of atoms, ie ONE SOLID. (Gif: homemadetools.net/forum/cold-wel…)

@PhysInHistory A funny quote from the man who established the widely popular Christmas lectures where he educated the masses about the modern science of his time 🤔

"Lectures which really teach will never be popular; lectures which are popular will never really teach." - Michael Faraday

@cplberry Remember that Middle Earth was written by a man from the British Isles. So he may have also called these the Gravy Rings of Power 🍩

The existence of lembas implies that baking is amongst the arts mastered by Elves. Hence, we may infer there exist cakes, and possibly pastries, beyond the ken of mortal men. My pitch is for the story of an Elf running a patisserie in Middle Earth: The Ring Doughnuts of Power

On February 9, 1990, Carl Sagan gave this speech before the 5th Emerging Issues Forum at NCSU, expounding on climate observations and energy strategies for a sustainable future, emphasizing solar [full speech: buff.ly/3RZhLOY]

Age when achieving tenure 1953 vs. 2022

@FinitePhysicist There is no aspect of the Newtonian limit of GR that relates to spatial curvature, it's all about time. Geodesics in GR are *longest*, proper-*time* curves (not *shortest*, *spatial* curves). In other words: everybody is lying with curved sheets explaining solar-system gravity✨

teach me your favorite physics fact :)

@FinitePhysicist I know this is a joke, but it is actually also a pretty valid jab at the foundations of QFT

I barely know how to normalize wavefunctions and now you want me to *re*normalize it???

🌃Still time to register for tonights' talk about gravitational waves at UCD!

Continuing with some of the talks at the #eetm2022, Matteo Breschi is telling us about the analysis of neutron star binary mergers💫💥 Big plans for the next-gen gravitational-wave detectors!

🪐The remnant of a binary neutron star compared with the scale of the Earth. Impressive! (A video Wolfgang Kastaun just showed us at the #eetm2022) youtube.com/watch?v=xIthgc…

Lovely choice of illustration picture for collaborative challenges when developing the Einstein Toolkit by Roland Haas 🦍🦍#eetm2022

🛝The talk was very clear and you can find the slides here (may or may not contain fastfood, depending on reading): ianhawke.github.io/slides/et-2022/

@IanHawke now gave a succint summary of the actual numerical methods used in numerical relativity. The units of the axis on the top right aren't burgers 🍔, it refers to the Burgers' equation 😁 #eetm2022

This is what I love about numerical simulations as compared to analytical work. It is just so much more visually engaging ✨(From the talk about GRMHD by @BrunoGiacomazzo at the #eetm2022)

Miguel Zilhão gaves a great summary of numerical relativity at the European Einstein Toolkit Meeting. Plus. Bouncy stuff 🫧 (video of head-on collision of boson stars) #eetm2022

Enjoyed the first talk at the 2022 European Einstein Toolkit Meeting by @scriwalker ! Takeaways: - Waveform detections work like Shazam 〰️ - EOB is pepsi, Phenom is Coke 🔵🔴 - Sheldon Cooper thinks numerical relativity is just typing up things, Sascha disagrees 🧮 #eetm2022

I had read the Sandman comics two times. And I only got the Cereal convention pun today when watching the netflix show🤦‍♂️ #sandman
