Citizen science: From the cosmos to the classroom

Citizen science projects offer the general public, or segments of that public such as school students, an opportunity to take part in scientific research. The Extreme Energy Events (EEE) Project in Italy is a cooperation ...

New type of entanglement lets scientists 'see' inside nuclei

Nuclear physicists have found a new way to use the Relativistic Heavy Ion Collider (RHIC)—a particle collider at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory—to see the shape and details inside ...

sPHENIX assembly update: Magnet mapped, detectors prepared

Physicists, engineers, and technicians at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory are rounding out the year with key developments to a house-sized particle detector that will begin capturing collision ...

A sensor (also called detector) is a device that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument. For example, a mercury-in-glass thermometer converts the measured temperature into expansion and contraction of a liquid which can be read on a calibrated glass tube. A thermocouple converts temperature to an output voltage which can be read by a voltmeter. For accuracy, most sensors are calibrated against known standards.
