Welcome to the Advanced Scientific Mathematics section of stemNRICH . This contains a set of activities designed to develop the advanced applied mathematical skills needed to make the most of the study of the physical sciences or engineering at university. These problems naturally follow on from the more elementary core scientific mathematics section of stemNRICH and are primarily intended for those who intend to study physics, engineering or applied mathematics at university.
