A common question arises: can density be determined using the free space measured on a gas adsorption analyzer, rather than a device specifically designed for density measurement? This article ...

Measuring density is crucial in manufacturing many of today’s products. Being able to characterize the structure and quality of solid materials quickly and efficiently can not only help guide ...

I HAVE just seen in the report of the proceedings of the Physical Society (NATURE, January 15, p. 260) the account of the ingenious and very important experiments proposed by Drs. König and Richarz to ...

Researchers are developing a new technique to help visualize the complex internal layering and anomalous structures inside planetary bodies, including the Moon. Credit: NGC 54/Wikimedia, CC BY-SA 4.0 ...

Scroll down for a quick way to measure snow density using a measuring cup, then get out there and start scooping! Density is a measure of the mass per unit volume of a substance. Think of it as the ...

IN NATURE for March 5 (p. 408) Prof. Mayer suggests an improvement in our method of determining the mean density of the earth, from which it appears that our plan has not been properly understood.
