I've fired one of America's most powerful lasers-here's what a shot day looks like

Charging the capacitor banks initiates a tense moment in the control room, where silence prevails as everyone focuses on the monitors. After confirming the charge, the shot is fired, releasing stored energy into the beam.

NIST's Quantum Breakthrough: Single Photons Produced on a Chip

NIST has developed a chip that reliably emits a single photon on demand. This ability will improve the efficiency of QKD (quantum key distribution) as we prepare for the arrival of quantum computers. Quantum computers will upend current cryptology by using Shor's algorithm to rapidly negate the current public/private key secure encryption methods. This has largely been solved by NIST's post quantum cryptology (PQC) algorithms.

Time is real - if you view it through the lens of heat | Aeon Videos

The way most people think about time is wrong. The notion that we share a 'common time' moving in a single direction is a useful illusion but, as physicists have understood since the discoveries of Albert Einstein, it doesn't comport with our understanding of the Universe. However, as the Italian theoretical physicist and writer Carlo Rovelli argues in this short documentary from Quanta Magazine, this doesn't mean we should abandon the concept of time altogether.

NMSurf on the decision to deploy Taara Lightbridge free-space optics: Interview

NMSurf is one of the largest fixed wireless providers in New Mexico, serving the central and northern area of the state. La Bajada was previously served by a 3-Gig microwave middle-mile connection. But, Catanach said, the bandwidth was becoming insufficient. New microwave licenses are hard to come by in New Mexico, he added, because the state itself claims many licenses for radio communications.

Taara Beam provides 25Gbps connectivity over invisible beams of light

Light-based internet provider Taara, which spun out of Alphabet's "moonshot" incubator last year, just launched Taara Beam to provide 25Gbps connectivity within cities over invisible beams of light - line of sight permitting. Unlike last year's Taara Lightbridge, which connects communities separated by water and mountains at distances up to 20km (over 12 miles), the shoebox-sized Beam can be mounted to street poles and roof tops for city-wide connectivity at distances up to 10km. The 8kg (less than 20 pounds) device typically consumes about 90W.

The science behind why some auroras have such stunning wave patterns

Auroras are nature's most special light show: when charged particles from the sun hit our atmosphere, they can generate bright colors that dance across the night sky near the Earth's poles. Auroras can come in various forms, including bands, rays, patches and more. But why auroras form these patterns is less clear. Now, researchers say they've identified the battery that powers at least one kind of auroraaurora arcs.
