In recognition of the 2011 'International Year of Chemistry', a public lecture hosted by Charles Sturt University (CSU) and Wagga Wagga City Council will explore how a series of seemingly unrelated chemical discoveries changed the course of history. Professor of Chemistry at Macquarie University in Sydney, Peter Karuso, will trace chemical connections from the humble shipworm to the discovery of antibiotics. "I'm hoping to show people how important chemistry is to their lives by showing how chemical discoveries have changed the course of history over and over again," he said. "Chemistry is so interesting and so powerful that it deserves the best and brightest minds. I hope in some small way to inspire young people and their parents to take an interest in things chemical as I am sure that chemistry will be at the heart of solutions to many of our current and future problems."
