Country cousins: Climate connections and land urbanization dynamics
(Phys.org) -- What’s in a name? Quite a bit in climate science, where the term teleconnection refers not to digital communications, but rather to a recurring and persistent large-scale pattern of pre ...
Is a classical electrodynamics law incompatible with special relativity?
(Phys.org) -- The laws of classical electromagnetism that were developed in the 19th century are the same laws that scientists use today. They include Maxwell’s four equations along with the Lorentz la ...
Good vibes: Coupling electron spin states and carbon nanotube vibrations
(Phys.org) -- An electron’s spin is separate from its motion, and is suitable for use in both highly-precise magnetic sensing as well as a qubit in quantum computing. Recently, scientists at the University ...
