Obtaining split-second measurements relies on faultlessly rounding a raw time recorded by a stopwatch or electronic timing system to a submitted time. Researchers at the University of Surrey found certain stopwatches commit rounding errors when converting raw times to final submitted times. In American Journal of Physics, they outline a series of computer simulations based on procedures for converting raw race times for display.
For the past eight years, Sandia National Laboratories manager Joel Wirth has been working afterhours in his home garage with his crew chief — his father, Jack Wirth, a retired electrical engineer from Sandia. Together, they’ve built one of the fastest 1927 Model T roadsters in the world.
