Einstein on Einstein Hanoch Gutfreund & Jürgen Renn Princeton Univ. Press (2020) Albert Einstein admitted in his final essay, ‘Autobiographical sketch’, that fellow physicists opposed his quest to unify the general theory of relativity with quantum mechanics. But he took comfort from philosopher Gotthold Lessing’s dictum: “The search for truth is more precious than its
Tiphaine Kouadou is a PhD student who is supposed to finish her dissertation this year and Mattia Walschaers is a CNRS research scientist. Both work in the multimode quantum optics group at the Laboratoire Kastler Brossel (LKB) in Paris, France, which is affiliated with Sorbonne Université, CNRS, ENS Université PSL, and Collège de France.

In New York, the epicenter of the COVID-19 outbreak in the U.S., the city’s health department put out a set of guidelines entitled, “Sex and coronavirus disease.” One piece of official advice: “You are your safest sex partner.” Dating is hard enough in the best of times. Throw in government directives like this, plus nationwide
Raytheon and a Northrop Grumman/Ball Aerospace team designed competing sensor payloads for the Next-Gen OPIR geosynchronous satellites. WASHINGTON — Two sensor payloads for the U.S. Space Force’s new missile warning satellites have passed a key design review. One of them will be selected for the first Next-Generation Overhead Infrared satellite scheduled to launch in 2025.
In the last two months, oil has hit two very different first-of-its kind milestones. In April West Texas Intermediate, the U.S. oil benchmark, plunged below zero and into negative territory for the first time on record. Meanwhile May is shaping up to be WTI’s best month ever, going back to the contract’s inception in 1983—an
Riana Pfefferkorn Contributor The debate over encryption continues to drag on without end. In recent months, the discourse has largely swung away from encrypted smartphones to focus instead on end-to-end encrypted messaging. But a recent press conference by the heads of the Department of Justice (DOJ) and the Federal Bureau of Investigation (FBI) showed that

WASHINGTON — To get a new, state-of-the-art crewed spacecraft ready to carry astronauts, SpaceX and NASA had to overcome problems with a technology long thought to be understood. One of the last tests that SpaceX had to complete for the Crew Dragon was for its Mark 3 parachute system. The company announced May 1 that
On the move: time sequence of the electron distribution of the molecule 1,3-cyclohexadiene after it is excited by a light pulse. (Courtesy: SLAC) Scientists in the US and UK are the first to observe electrons rearrange their positions in molecules during the early stages of a light-driven chemical reaction. They did so by firing ultrashort
One of the biggest technology takeaways of the last couple of months has been that organizations need confident, wide-ranging digital strategies to stay afloat, and Facebook — in its wider bid to build products to serve businesses — is taking note.
