The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold together the cores of our atoms. But they can’t say what gravity particles, if any, delight us as babies by enabling our spoons to plummet… Continue reading Old ‘Ghost’ Theory of Quantum Gravity Makes a Comeback

Mixing Is the Heartbeat of Deep Lakes. At Crater Lake, It’s Slowing Down.
In the past, when summer nights grew cold, the lake released the day’s accumulated heat, causing surface water to become denser and sink. This phenomenon drives the shallow mixing that occurs in summer. As nights have warmed, however, this process has weakened, and mixing has slowed. Counterintuitively, as the layer of surface water has become… Continue reading Mixing Is the Heartbeat of Deep Lakes. At Crater Lake, It’s Slowing Down.

First, they assumed the opposite of what they wanted to show: that when you slightly perturb the wire frame that defines your surface, a singularity (a single point) always persists. Each time… Continue reading New Proofs Probe Soap-Film Singularities
