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 ...

Short-term memory is finite and fills up quickly. Here are 7 ways we can free up space for clearer-headed mathematical thinking.

If the mention of algebra conjures bad memories of math classes, a Python library called SymPy could change your mind about ...

A team of international physicists has brought Bayes’ centuries-old probability rule into the quantum world. By applying the “principle of minimum change” — updating beliefs as little as possible ...
