Two-color glowing molecule could make wind tunnel tests more accurate
Most sensors can measure only one thing at a time, like a thermometer for temperature or a pressure gauge for pressure. Measuring two properties accurately from the same surface at the same moment usually means using two separate instruments—adding cost and complexity to the process.
