📖Read Time: 3 minutes 📊Readability: Advanced (Technical knowledge needed) 🔖Core Topics: universe, curvature, spatial, finite, flat Standard cosmological models are classified by spatial curvature into three broad types: open, flat, and closed universes. These correspond to negative, zero, and positive …

The biggest open problem in the foundations of physics is that Einstein’s theory of gravity, General Relativity, does not cooperate with quantum mechanics. Physicists have tried to solve this issue by coming up with a theory of quantum gravity, but …

Fabrics flutter in seemingly impossible ways in artist Thomas Jackson‘s images. But despite first appearances, each photograph is true to life; the fabrics are suspended on taut lines. Their dance is driven by wind energy, drag, tension, and flow–not manipulated …

This posting is mainly intended to provide some links to material about AI in math and physics that I’ve found interesting. I confess that to a large degree I’m trying to avoid seriously learning about exactly what is going on, …

As the Archives Fellow, I was most excited to interview women in the physical sciences for the American Institute of Physics (AIP) oral history collection . Oral histories create historical records of subjective experiences—the details not captured by solely looking …

Building on a long-standing MIT–IBM collaboration, the new lab will chart the convergence of AI, algorithms, and quantum computing. The following is a joint announcement by the MIT Schwarzman College of Computing and IBM. IBM and MIT today announced the …

Recently, physicists at CERN announced that they’d re-discovered an anomaly in the way that certain particles (called B mesons) decay. The anomaly has been noted in multiple other analyses over the years, though most recently it had disappeared. It could …
