Mercedes invented a joystick-controlled car. In 1966, Mercedes released the Mercedes F200. One of its most defining features is its joystick controller that replaces the steering wheel and pedals. The car could sense which side the driver was sitting on, so someone could control it from the passenger seat.
100 Mind-Blowing Defining Facts
Science has several different ways of defining time. To cover just a couple: There’s astronomical time, which is measured by how long it takes Earth to rotate on its axis. In astronomical time, a second is 1/60th of a minute. And then there’s atomic time, which dictates the numbers that you’ll see on a clock. According to atomic time, one second equals 9,192,631,770 oscillations of a cesium-133 atom. Measuring the vibration of an atom—which, in simple terms, is the gist of what oscillation is—is the most accurate way to track time.
