When you’re in school, you often have to juggle your scientific and historical subjects separately – but today we’re combining the two! Years of research, heartbreak, triumph and rich history went into supplying you with the scientific knowledge that you have at your fingertips every time you open a science book, and it’s time to learn about some of it! What do you know about the history of chemistry? Let’s find out!
