The science behind everyday phenomena, such as what makes methanol more toxic than ethanol, and how we determine the age of dinosaur fossils!

A Brief Introduction to Forensic Science

‘Evidence never lies.’ Criminal Minds, CSI, Law & Order – the popularity of crime television shows might have a bit to do with how the audience gets a little taste of forensic technology. After all, not many people out there would have had the first-hand experience of having their DNA sampled!

Flash Points, Autoignition and Fahrenheit 451

‘That ethanol you spilled has a flash point of 14°C, your clumsiness is going to set the room on fire!’ A highly unlikely scenario actually; we often mistake flash points of substances as the temperature at which they will catch fire. For ethanol this would require its surroundings to be a toasty 365°C, so what’s the big fuss about its flammability? And how does Fahrenheit 451 tie into all this?

Aromatherapy – Probably Useless, Perhaps Even Dangerous

Essential oils for aromatherapy are all the rage nowadays; the ‘essence’ of all that good stuff in plants captured and inhaled to treat diseases.
