With clocks, we measure the numerical order of a material change, i.e., motion running in space. There is no experimental evidence that clocks measure time. It is convenient to replace the concept of ...

Numerical integration has been used to investigate the adequacy of the lunar theory for high precision applications and to examine the problem of modelling the apparent departures of the lunar motion ...

With board exams approaching, many students find numerical problems in Physics and Chemistry difficult and time-consuming. These questions test more than memory. They check whether a student ...
