Hear With Your Eyes: Affordable Audio Visualization Under $200

An affordable DIY project uses modified Schlieren imaging to visualize sound waves as visible light and shadow patterns for under $200, making the physics of sound accessible. The system overcomes the high-speed capture challenge by using a synchronized strobe light triggered by the audio signal,...

NASA's Test Flight Paves Way for Supersonic Travel's Return

NASA's X-59 Quesst jet completed its first flight, aiming to reduce sonic boom noise and potentially enable future supersonic travel over populated areas. The aircraft's innovative design, including a long nose and top-mounted engine, minimizes shockwaves to produce a quieter "sonic thump" instea...

NASA's Silent Supersonic Jet Makes Historic First Flight

NASA's X-59 aircraft completed its first flight, advancing efforts to enable commercial supersonic travel over land by reducing disruptive sonic booms. The X-59 is designed to transform shockwaves into a soft thump instead of a loud boom, aiming to influence regulatory changes that currently ban ...
