When New England was hit by Tropical Storm Irene in 2011, there was not a satellite monitoring tropical storms that far north; the Tropical Rainfall Measuring Mission (TRMM) was operating in a band between the 35-degree latitudes. The Global Precipitation Measurement (GPM) mission will change that. GPM will build upon TRMM's capacity by examining a larger swath of Earth with instruments that are more advanced and more sensitive. This video introduces the GPM satellite, its instruments and their capabilities.

Mathematicians often argue that anything which can be represented numerically or algebraically can also be represented geometrically. This is perhaps true even to the extent that simple numeric calculations can be demonstrated geometrically. This example illustrates one such geometric process of addition.
