Throughout his life the German writer and statesman Johann Wolfgang von Goethe had a deep fascination for the physical and metaphorical effects of light on humans. From sunsets to rainbows, from the blues of the sky and the ocean, to the remarkable range of colours of plants and animals, our first experiences of light and colour are through what we see in the natural world.
However, the importance of light reaches far beyond life on Earth. Through major scientific discoveries and technological advancements, light has helped us to see and better understand the universe. 2015 marks an important milestone in the history of physics: one hundred years ago, in November 1915, Albert Einstein wrote down the famous field equations of General Relativity, which showed through a series of experiments centred on the concept of light, how light was at the centre of the very structure of space and time.
All over the globe, people are using light to discover solutions for society’s most pressing problems. From 3-D printing to bringing energy solutions to developing regions, light is key in driving economies and encouraging development in the 21st Century. It has revolutionized medicine, opened up international communication via the Internet, and continues to be central to linking cultural, economic and political aspects of the global society.
For these reasons and more, the Science Film Festival invites audiences in 2015 to discover the different roles light and its applications play in our everyday lives and what it reveals about the nature of the universe.
