“The IBM Simon was the first phone with a touchscreen in 1992 — it’s also referred as the first “smartphone,” though the term was not yet coined. A few competitors came out in the early '90s, but most mobile devices with touchscreens were more like PDAs”。
“The first rockets were used as propulsion systems for arrows, and may have appeared as early as the 10th century Song dynasty China. However more solid documentary evidence does not appear until the 13th century. The technology probably spread across Eurasia in the wake of the Mongol invasions of the mid-13th century. Usage of rockets as weapons before modern rocketry is attested in China, Korea, Indian subcontinent, and Europe. One of the first recorded rocket launchers is the "wasp nest" fire arrow launcher produced by the Ming dynasty in 1380. In Europe rockets were also used in the same year at the Battle of Chioggia. The Joseon kingdom of Korea used a type of mobile multiple rocket launcher known as the "Munjong Hwacha" by 1451. Iron-cased rockets, known as Mysorean rockets, were developed in Kingdom of Mysore by the mid 18th century in India, and were later copied by the British. The later models and improvements were known as the Congreve rocket and used in the Napoleonic Wars.
Use of liquid propellants instead of gunpowder greatly improved the effectiveness of rocket artillery in World War I, and opened up the possibility of manned spaceflight after 1918.”
