Albert Einstein submitted "The Field Equations of Gravitation" to the Prussian Academy #OTD in 1915.
After years of work culminating in a frenzied month-long race against David Hilbert, Einstein had finally obtained the correct form of the field equations for general relativity. 🧪 🔭 ⚛️

With many physicists arriving daily at Bluesky I’ve created a comprehensive list -which I update daily- with Cosmologists, Astrophysicists, Gravitational Wave Astronomers, Particle Physicists… Please SHARE so it reaches more people! 🤩 Warning: it may contain Mathematicians

I am delighted that we our hosting the joint GR & Amaldi meetings in Glasgow in July 2025
Abstract registration is now open iop.eventsair.com/gr24-amaldi1...
The conference will cover gravitation, gravitational-wave and multimessenger astronomy, cosmology and relativistic astrophysics, and more!

Recently moved institutions to FZU - Institute of Physics of the Czech Academy in Prague.
This is a picture of the entrance to the new Solid State building (the main building where I work is in the back).
