This fully working Python project demonstrates a method of creating a gradient fill, to add depth to flat looking rectangles. It also shows how to use transparency effects to change the shape of gradient filled surfaces, how to plot points of a circle, and some examples of why you would want to do so. The activity...

This Catalyst article explores gravitational waves which have been observed for the first time, a century after they were first predicted by Albert Einstein.

A Catalyst article about green chemistry. Many reactions take place in solution. Water is a familiar solvent but there are many others, including a rather surprising one, carbon dioxide, which is a non-polluting ‘green’ solvent. The chemical industry relies on solvents to produce many everyday products, such as:...
