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 ...

Temperature is one of the most frequently measured parameters, and with good reason. Temperature serves as an important indicator of the condition of an object in machinery, medical diagnostics, ...

Scientists at the National Institute of Standards and Technology (NIST) have created a new thermometer using atoms boosted to such high energy levels that they are a thousand times larger than normal.

Infrared (IR) thermometers allow noncontact measurement of surface temperatures by analyzing the invisible, infrared spectrum emitted from an object. IR devices, such as the Fluke 61 and 65 IR ...

In everyday life, measuring temperature is pretty straightforward. But in the quantum world, which deals with the super small and the ultra-cold, determining how hot or cold something is starts to get ...

I tested six popular thermometers and compared their ease of use, reading speed and design, and found two models I’d recommend to anyone for at-home use.
