 I'm Bob Furbank. I'm the director of the ARC Center of Excellence for Translational Photosynthesis. I've been working on the process of photosynthesis in plants and how to improve it for the last 40 years. It all started, for me, 45 years ago in a physics lesson in year 10 at high school. We had a physics teacher who was pretty odd, really. He used to come into class with an orange paisley tie and a purple jacket, and he liked nothing better than filling up the blackboard with equations by the end of the session. But one day we had a lesson where he really intrigued me, and he hooked me on a topic that stayed with me for the next 45 years. He took out a prism, a glass prism. He put it on the table at the front of the classroom, and he shone a light through it. Across that rainbow of light, he pointed out the fact that plants absorb red light, and blue light, and reflect green light. And that is why plants are green and the pigment responsible for that is chlorophyll. With the red and blue light, plants use that energy to absorb carbon dioxide from the atmosphere and convert it into carbohydrates, which the whole world depends upon for their foodstuffs. So that little bit of inspirational lesson gave me a 40-year research career down the track.
