Students will be able to explain that the density of a substance has to do with how heavy it is compared to the size of the object. Students will also be able to explain that density is a ...

MIT researchers found a way to measure cell density quickly and accurately -- measuring up to 30,000 cells in a single hour. They also showed density changes could be used to make useful predictions, ...

For a given set M of positive integers, a well-known problem of Motzkin asked to determine the maximal asymptotic density of M-sets, denoted by μ(M), where an M-set is a set of non-negative integers ...

The most frequently quoted hydrogen content quantity, in terms of storage applications, is wt.%: the weight percent capacity or the gravimetric storage density of a material. The calculation or ...
