PITTSBURGH (KDKA) -- We have done a lot of experiments and covered a lot of topics. This time, we are going to play around with density, and use its ingredients to make some weird science. We have ...

Everyone probably already knows about the density triangle. If not, here is a quick overview. The density of a material is a measure that is independent of the size of that object. You can calculate ...

Recently, the string density problem, considered in the pioneering work of M. G. Kreĭn, has arisen naturally in connection with the Camassa-Holm equation for shallow water waves. In this paper we ...

It is tempting to think that some materials are always heavier than other materials. For example, someone might say that metal is heavier than air. But it depends on how much of each material there is ...
