Have you ever placed a thermometer under your tongue and wondered how that tiny device knows if you have a fever? Or checked the weather and thought about how scientists measure temperature so ...

The measurement of temperature in high-temperature environments remains a central challenge across many scientific and industrial domains, from aerospace engine monitoring to materials processing.

Each body with a temperature higher than absolute zero (–273.15 °C = 0 Kelvin) releases electromagnetic radiation from the surface. This radiation is proportional to its intrinsic temperature. One ...
