Tech solutions on Instagram: "Walter Lewin demonstrates the concept of thermal expansion by clearly showing how materials change their dimensions when temperature varies, turning an abstract idea into a vivid physical reality. Through simple yet powerful experiments, he heats and cools solid objects to reveal how atoms vibrate more vigorously as temperature rises, causing the material to expand, and contract again as it cools. His engaging explanation and hands-on approach make it easy to unders

Sports Tech Era on Instagram: "The phenomenon of thermal inertia in action: silica fibre fabric can survive an astonishing 1000°C flame without burning or degrading. Watch as a blazing torch is applied directly to the material, yet the fabric remains intact, showcasing its incredible heat resistance and protective qualities. This advanced textile technology demonstrates how engineered silica fibres can withstand extreme temperatures, making it ideal for high-performance applications in fire prot
