Want facts and want them fast? Our Maths in a minute series explores key mathematical concepts in just a few words.
The COVID-19 pandemic has amplified the differences between us. Understanding these inequalities is crucial for this and future pandemics.
Now it's the turn of mathematicians to help to improve the communities of the future.
There have been accusations that the modelling projecting the course of the pandemic was too pessimistic. Are they justified?
We all know what turbulence is, but nobody understands it.
Find out about the beautifully intuitive concept that lies at the heart of calculus.
Electrons can be "ripped" away from their atom with the application of energy in one of many forms. One method that was common in every home for years, was in vacuum tubes. Also called electronic valves in some countries. Also, in CRT's, like television picture tubes. In this application, heat was applied to a little piece of tungsten, containing a bit of thorium. Electrons jump off of their atoms, many into the vacuum in the tube, where they are used to amplify signals, or used to bombard the phosphorus screen on a television tube, forming the TV image.
