Mach-Talk... Your speed relative to the speed of sound in the medium you are traveling is called your Mach Number. Mach-1 is the speed of sound. Mach-2 is 2x the speed of sound, etc. At Mach-1 and higher you create a sonic boom. High Mach numbers cause more energetic booms. — PolitiTweet.org

More Mach-talk… “Mach,” in reference to speeds relative to sound, is named for the nineteenth-century Austrian philosopher-physicist Ernst Mach who, among other subjects, researched shock waves in air, which we more commonly call sonic booms. — PolitiTweet.org
