New analysis rescues quantum wave-particle duality

A basic principle of quantum mechanics has been reaffirmed. Stop the presses. (Or start the tweeting.)In 2012, experimenters in Germany had supposedly shown that you could observe both wave and particle properties of light in one experiment. That result ...

Dark Energy, Faster-Than-Light Travel, and Fine Structure Bombs [Uncertain Principles]

Last week’s talks were using sci-fi space travel as a hook to talk about relativity, and my original idea for the talk was to explain how faster-than-light travel ultimately ends up violating causality. Some observers will see effects happening before ... [Published ScienceBlogs : Combined Feed - May 06 2014]

Quotes

...an important index [of] human civilization – 'global aggregate knowledge of chemical thermodynamics' — has declined 65 percent," Deutch adds. "Given all of Irwin’s contributions, I have thought for some time that his work has not received the recognition it should from the scientific community.”  "
