Differential equations are fundamental tools in physics: they are used to describe phenomena ranging from fluid dynamics to general relativity. But when these equations become stiff (i.e. they involve ...

In this video, we provide essential "math help" by explaining how to simplify complex fractions, which often involves careful "algebra" and understanding "rational functions". This "math tutorial" ...

If you know the atoms that compose a particular molecule or solid material, the interactions between those atoms can be determined computationally, by solving quantum mechanical equations—at least, if ...

(Nanowerk Spotlight) As our digital devices handle increasingly complex computations, scientists have looked to physics for inspiration on new computing paradigms. Rather than shuttling electrical ...

Learn how to simplify a complex fraction by multiplying by the LCD. In addition to simplifying the complex fraction we will identify the excluded values. The values that make it zero. I make short, to ...
