How do we compare the performance of different tests for a disease? It all depends on the values of the 'sensitivity' and 'specificity' and a comparison between the two via a ROC curve. Check out the latest article by TRM intern Amie Campbell to learn whether you should take the red or blue test - read at tomrocksmaths.com (link on profile) #tomrocksmaths #diseasetest #covidtest

With this weather in the UK at the moment, I'm sure like me you could all do with a bit of sun. So, inspired by their excellent performance on Friday night @ssearena here's a cracker from @offspring - 'Staring at the Sun’. Accompanying photo of me being suitably cold following a session of swimming in the Atlantic Ocean… Listen on the ‘Music’ page at tomrocksmaths.com (link on profile) #tomrocksmaths #offspring #seaswimming

When in Rome… but did you know the colosseum isn’t in fact a circle? Historians believe the elliptical shape was chosen as it allows for a larger perimeter for the same area, which means more seats for spectators. For example, doubling the area of an ellipse gives a much larger perimeter than building a circle of the same area. Do the calculations for yourself and see if you can work out why! #tomrocksmaths #colosseum #rome
