Bruno Giménez Umbert

Happy Birthday! 🙂

You could also work with Debbie Leung, Richard Cleve, David Gosset, Luke Schaefer, Ashwin Nayak, Norbert Lutkenhaus, Mike Mosca, Christine Muschik or some combination of us if you do theory.

The hierarchy problem (finetuning) of the Standard Model of particle physics is often presented as the question 'why the weak scale is so much smaller than the Planck scale'

But there is also a geometric interpretation that can be understood with little maths (but a lot of physics)

This is the 800th LHCb paper. 🎉

I wish you the best in your job search!

Time is running out to apply for our workshop:

"50 years of the black hole information paradox: November 3 -7 , 2025"

at Simons Center for Geometry and Physics

Congratulations to Luis Lehner on being named to the Simons Collaboration on Black Holes and Strong Gravity.

Lehner is one of 12 researchers working to build a theoretical framework for unlocking the secrets of gravitational wave data.

Complexity Postdoctoral Fellowships at the Santa Fe Institute @sfiscience.bsky.social are now open for applications!

(I should also announce a postdoc opening with me at Johns Hopkins pretty soon.)

Unless deported upon arrival, I will be in Boston from June 1 to June 7. If anyone around the area wants to hang out, feel free to DM me!

PSA: when a collaboration whose name starts with DE says they have found evidence for non-standard dark energy, the community should take that interpretation with more skepticism.

DESI does not show that w0wa explains there data. Eg neutrino mass remains negative even with w0wa

I totally relate to that

Zelensky is a hero by any sensible measure. A leader inspiring his nation in the midst of an invasion by a powerful, repressive dictatorship. The fact that any American can think of him as the bad guy just demonstrates the triumph of tribalism over principle.

Good stuff happening in a wonderful place in July
