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 ...

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 ...

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 ...

Kathryn Jones, teacher at Carl H. Kumpf Middle School and Arthur L. Johnson High School in Clark, provided an opportunity for her students to calculate the density of water. The students used their ...

A planetary scientist has used careful mathematical calculations to determine the density of Mercury's crust, which is thinner than anyone thought. Mercury is small, fast and close to the sun, making ...

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.
