In most applications, level measurements need to be quantified and sent electronically to an automation system, which requires some type of instrument. Sorting through the instrument selection process ...

Scientists have measured the density of liquid iron -- the main component of rocky planet cores -- under conditions similar to Earth's liquid core: 1,000,000 atmospheres and 4,000 degrees Celsius.

Compare the density of water to that of different liquids. Krystal Balmes and Sahil from the Brooklyn Preschool of Science make predictions about the density of water to that of honey, corn syrup, and ...

This release is also available in German. For oceanography – and there in particular for the description of ocean currents – accurate measurements of the density of sea water are of great importance.

Using the large synchrotron radiation facility SPring-8 in Japan, a collaboration of researchers from Kumamoto University, the University of Tokyo, and others from Japan and France have precisely ...
