The Probability Density Function: A Known Unknown
I recently listened again to Richard Feynman explaining why the flowing of time is probably an illusion. In modern physics time is just a coordinate, on the same footing as space, and the universe can be described as a four-dimensional object — a spacetime block. In that view, nothing really “flows”. All events>
A planet around the mass of the Earth has been found, orbiting a star in the Alpha Centauri system; the nearest to Earth and also the lightest exoplanet ever discovered around a star like the Sun. >
In 2016, The Frank R. Lautenberg Chemical Safety for the 21st Century Act amended the Toxic Substances Control Act (TSCA) and created a mandatory requirement for EPA to evaluate existing chemicals using transparent methodology and risk-based assessment. Not simplistic epidemiology.This was actually a good thing. We>
A gravity model of the Earth constructed with data from GRACE. Credit: University of Texas Center for Space Research and NASAIt is all about gravity these days. First came GRACE (Gravity Recovery and Climate Experiment) and then we'll have GOCE (Gravity field and steady-state Ocean Circulation Explorer). I'll reveal>
This idea dates back to the Russians in the early 1970s. The surface of Venus is far too hot, and the atmosphere too dense, for Earth life. However, our air is a lifting gas on Venus with about half the lifting power of helium on Earth. A habitat filled with normal air will float high in the dense Venus atmosphere>
Physicists from the ATLAS experiment at CERN have confirmed one of the oldest predictions of quantum electrodynamics (QED), finding the first direct evidence of high energy light-by-light scattering, a very rare process in which two photons – particles of light – interact and change direction.>
