WebFeb 24, 2024 · Schrödinger wrote: "in a Geiger counter there is a tiny bit of radioactive substance, so small, that perhaps in the course of the hour one of the atoms decays, but also, with equal probability, perhaps none; if it happens, the counter tube discharges." The Geiger counter patiently watches (observes) the radioactive substance. WebFeb 2, 2016 · Estimating wave height is, at best, an inaccurate science. That’s because while rolling in waves and swells, a boater’s line of sight typically runs at an angle to the wave he is trying to measure, causing his perception to distort.
