But you may have noticed that experiments like the quantum mechanic’s mainstay, the double slit experiment, can be done in air. But describing a measurement in terms of information leads to another, possibly nightmarish, question: Is it possible to do a “partial measurement”, that gets only a little information? This is a partial measurement, because a full measurement would take the form of 100% probabilities. What’s very exciting is that you can slide cleanly from “no measurement” (50%/50%) to “total measurement” (0%/100%). “Measurement” and “quantum mechanics” may remind you of scientists in labs, but any interaction that conveys information (which in day to day life is basically all of them) is a measurement.
