Gravity Winners
May 29, 2020
The winners of the Gravity Research Foundation essay contest have been announced. Congrats to our members who have won prizes: Eduardo Guendelman (for "Lorentzian Quintessential Inflation" with David Benisty), Craig Hogan (for "Cosmological Constant in Coherent Quantum Gravity"), Thanu Padmanabhan (for "Principle of Equivalence at Planck Scales and the Zero-Point-Length of Spacetime"), and Maulik Parikh & Frank Wilczek (first prize for "The Noise of Gravitons" with George Zhariade).
INSPYRE!
Mar 23, 2020
FQXi is proud to support INSPYRE 2020, “The Hitchhiker’s Guide to the…Universe’”, which is dedicated to the hottest topics from particle physics to cosmology. This year lectures (in English) are online from 30th March to 3rd April. Open to all, especially students & teachers! The course is organised by FQXi's Catalina Oana Curceanu, senior researcher at the National Laboratory of Frascati (LNF), and you can read more here.
