Happy to announce our work on Coordinate Independent Convolutional Networks. It develops a theory of CNNs on Riemannian manifolds and clarifies the interplay of the kernels' local gauge equivariance and the networks' global isometry equivariance. arxiv.org/abs/2106.06020 [1/N]

Is de mysterieuze donkere materie in het heelal nu écht, of zien we de gevolgen van subtiele afwijkingen van de zwaartekrachtswetten? Nieuw onderzoek legt verschillende donkerematerie-modellen en alternatieve zwaartekrachttheorieën langs de meetlat. quantumuniverse.nl/donkere-materi…

By comparing the sizes of black holes before and after a merger, researchers have tested Hawking’s theorem on black hole areas. Physics - Black Hole Area Law Tested physics.aps.org/articles/v14/s…

Steven Weinberg, a titan of theoretical physics, has died at 88. In this 2015 interview, he discussed the nature of progress in science, problems with the multiverse, and his ongoing research. quantamagazine.org/steven-weinber…

I am happy to see Joanne Cohn gets credit for her key role in creating the (precursor to the) arXiv. She was doing this more than 30 yrs ago in her office across the hall from me at the Institute for Advanced Study (IAS). I was one of the 1st subscribers and contributors to her mailing list.

Uitstekend draadje van Hans Clevers, toonaangevend wetenschapper en oud-president van de KNAW - over zijn grote zorgen over de armoedige financiering van wetenschap in NL, maar ook over hoe ‘erkennen en waarderen’ goedbedoeld helaas juist een verkeerde impuls geeft. Lezen!

Maurice Weiler wrote an incredible bible on equivariance. You will not find a more thorough and richly illustrated introduction to the subject. It was a beautiful journey relating to concept in maths w/ Patrick Forré and to physics w/ Erik Verlinde. Grateful to be part of this.

Look what arrived! Maurice Weiler’s thesis (I’m on his thesis committee). Also basis of book with Patrick Forré, Erik Verlinde and Max Welling. maurice-weiler.gitlab.io/#cnn_book

Physics is mathematical not because we know so much about the physical world, but because we know so little: it is only its mathematical properties that we can discover. - Bertrand Russell

We have to remember that what we observe is not nature herself, but nature exposed to our method of questioning. - Werner Heisenberg

Why physicists now question the fate of the Universe The Universe's fate is known, so long as dark energy is truly a cosmological constant. With the Hubble tension and new DESI data combined, perhaps we need to rethink dark energy. bigthink.com/starts-with-a-…
