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

[Sophia Gad-Nasr @Astropartigirl]

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.

@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 🤔

[Vojtěch Witzany @w_vojtech]

@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 🍩

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

Pls

[the finite physicist @FinitePhysicist]

instead of listing authors in alphabetical order. or even by amount of contribution. papers should only have the ship name made by combining all author's names.

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✨

[Vojtěch Witzany @w_vojtech]

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

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

[Barry Wardell @barry_wardell]

Looking forward to the public talk "Exploring the Universe with Gravitational Waves" by Prof. Alicia M Sintes this evening at 6pm in the Moore Auditorium at UCD. If you want to come there is still time to register at https://t.co/2sh14bZgz6

[Vojtěch Witzany @w_vojtech]

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!

[Vojtěch Witzany @w_vojtech]

🪐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) https://t.co/WGjezdc2a1

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

[Vojtěch Witzany @w_vojtech]

🛝The talk was very clear and you can find the slides here (may or may not contain fastfood, depending on reading): https://t.co/9L1gEIkQpr

@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

[Vojtěch Witzany @w_vojtech]

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)

[Vojtěch Witzany @w_vojtech]

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

[Vojtěch Witzany @w_vojtech]

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 🧮

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