I learned about three inventions and one inventor. The inventions are the flying shuttle, the marine chronometer, and the leyden jar. The inventor’s name is Anders Celsuis. First, I learned about the flying shuttle. The flying shuttle unleashed fabric production capability and sped up fabric production. John Kay invented the flying shuttle. He went into the textile business for himself. Second, I learned about the marine chronometer. The marine chronometer is immune to temperature pressure. John Arnold built the flying shuttle. Without the chronometer there would be no British empire. Third, I learned about Anders Celsuis. He was born in 1701. He participated in the expeditions to determine the Earth’s shape. His temperature scale became the world’s standard in the 1950s. Last, I learned about the leyden jar. The leyden jar is a battery that stores charge. The leyden jar was the main source of electricity before generators.
