Although nonstandard analysis was developed in 1966 by Abraham Robinson, it is based off of Gottfried Wilhelm Leibniz’s construction of the calculus, created some 300 years earlier.

No matter how quickly a transition occurs, its inner workings can affect the dynamics of the system significantly. Here we discuss the way transitions can be reduced to discontinuities without trivializing them, by preserving so-called hi...
