Historical names for January include its original Roman designation, Ianuarius, the Saxon term Wulf-monath (meaning wolf month) and Charlemagne's designation Wintarmanoth (winter / cold month). In Slovene, it is traditionally called januÃ¡r.
Chemical engineers use math frequently in the laboratory. They use advanced computer software to aid in their research and production processes to model theoretical synthesis techniques and properties of chemical compounds.
Electrical engineering is the most math heavy of the engineering disciplines. You rely heavily on differential equations when dealing with advanced circuit analysis and electromagnetism is basically a physics and math course. In a close second is mechanical engineering, which uses dynamics a lot. Chemical engineering is in last probably. Differential equations are used a lot, but that is true of all the engineering disciplines. Industrial engineering often has a lot of economics built in, which of course uses mathematics. This is all very subjective though, but I think it is a good characterization.
