Lee Smolin's "Einstein's Unfinished Revolution" examines the problem of quantum physics and reality: NPR

Does reality need realism? If that seems like a strange question to you, keep in mind the fact that this is extremely pressing for physicists and their most successful theory about the physical world. This theory is called quantum mechanics – and every digital electronic device you've ever used owes its existence to the understanding of physics at the atomic …

Thermodynamic magic enables cooling without energy consumption

Theoretically, this experimental device could be boiling water to ice without using any energy. Credit: Andreas Schilling, UZH              Physicists at the University of Zurich have developed an amazingly simple device that allows heat to flow from a cold to a hot surface without to external power supply. Intriguingly, the process initially appears to contradict the fundamental laws of physics. …

California earthquake: TWO MILLION quakes rock South California – One every 3 MINUTES | Science | News

The California earthquakes silently rocked the US state between 2008 and 2017. Geologists at the California Institute of Technology (CALTECH) trawled through 10 years worth of seismic data to pinpoint the new tremors. The incredible earthquake discovery has expanded South California's catalog of known quakes from 180,000 to an astounding 1.8 million. Caltech's geologists published their findings on April 18 …

Tiny mercury can have a solid metallic core that competes with the earth

A solid metallic nucleus nearly as big as Earth could lurk deep in the smallest planet of the Solar System. This emerges from new research based on data collected by NASA's NASA (Mercury Surface, Space Environment, Geochemistry and Ranging) ( MESSENGER ) mission. This spaceship orbited the tiny planet for four years before deliberately crashing on the surface of Mercury. …

Chemists take a closer look at the point where water meets air

Schematic representation of the water surface, where the spectral signature of an isotopically labeled water molecule is isolated with two infrared lasers. Picture credits: Nan Yang Despite its central place in so many processes vital to life on Earth, water remains a chemical puzzle in many ways. One of these mysteries is the nature of the water at the point …
