nexus of money on Instagram: "Most phone cameras just capture the moment. This one fights physics to make it perfect. 📱🤯 You are watching a masterclass in electromechanical engineering. The Samsung Galaxy S23 Ultra's camera doesn't just have optical image stabilization (OIS); it has a "sensor-shift" system where the entire camera sensor physically moves on a microscopic gimbal. This allows the phone to counteract the user's movements in real-time. Onboard gyroscopes and accelerometers measure

Knowledge Nexus on Instagram: "While most Japanese trains run on tracks, the phrase likely refers to Japan’s futuristic Maglev trains, like the Chuo Shinkansen, which use magnetic levitation to float above conventional tracks, eliminating friction for extreme speeds, or possibly unique cases like local trains using Shinkansen infrastructure or even decommissioned lines becoming walking paths. The core idea is advanced rail tech where trains “don’t run on” tracks but use magnets to glide over the
