Useful Information - A Compedium of Facts & Figures!
Welcome to the usefulinformation.eu website, which has now had a long-overdue redesign! We have rebuilt the site from the ground up, using a "Mobile first" approach to ensure that all our content is easily available to users of mobile devices (The Periodic Table page will still benefit from being viewed in "Landscape" view on smaller devices). We shall soon be adding further content, so please bookmark the site!
