It has to be my electron microscopes – I heard of them as a child and saw them on TV science shows but I never dreamt I’d every get my grubby little finger on a million quid, two tonne shed sized microscope myself – and now I have two 🙂 I even get to teach people how to use them, some of my former students are now competitors and that’s fantastic as I know I’ve helped them find a career.
