Compound Interest is a site that aims to take a closer look at the chemical compounds we come across on a day-to-day basis, explaining them with easy-to-understand graphics. The site won the Association of British Science Writers’ Dr Katharine Giles Science blog award in 2018. The site is run single-handedly by me, Andy Brunning. I’m a chemistry educator based in Cambridge, UK, and create the graphics for the site in my spare time.
