Can ice sink in water? What is the temperature of outer space? Why do meteors glow? Can a candle flame melt iron? Is absolute zero truly attainable? What would happen if gravity suddenly disappeared? And why is the upper atmosphere colder than the air near the ground? In this second volume of his celebrated physics collection, Yakov Perelman takes readers beyond the familiar world of everyday mechanics into the fascinating realms of heat, electricity, magnetism, astronomy, relativity, and the microscopic universe. Through more than 100 intriguing questions, paradoxes, and thought experiments, Perelman transforms complex scientific concepts into engaging intellectual adventures. Each chapter challenges common assumptions and reveals the elegant principles that govern nature - from the behavior of atoms to the motion of planets. Written with clarity, wit, and an enduring sense of wonder, this timeless classic continues to inspire students, educators, engineers, and curious minds of all ages.
