Thomas has received a shiny new Travelling Microscope with a 0.01 mm precision vernier scale. There is only one thing he wants to talk about.

First Thomas talks briefly avbout his 205 mile (329km) ride for Education Support (the only UK charity dedicated to the mental health and wellbeing of education staff in schools, colleges and universities). He’s raised over £1,300 so far, and the donation page is still open.

We then thank Tim Browett for getting in touch. Tim is going to be our guest for Ways to teach… Space, so if you have any ideas please share them with us in the usual ways (@physicstp on twitter and a contact form on the web site).

Then on to the vernier scale, which was invented in 1631 by Pierre Vernier and is a simple way of taking high precision measurements. Thomas describes how he introduces it in class by making a large 1 cm scale vernier that can measure mm. This was the way Thomas taught himself to use it when he was doing A-Level and he thinks nothing beats the experience of working it out with a large scale where you can see things happening in front of you.
