Plastic fantastic: electronics for the 21st century
Plastics - or, more correctly, polymers have traditionally been used by the electronics industry as passive materials. Now however, new types of polymers have been discovered which behave as semiconductors. For example, they can emit light when subje....

Structures looking broadly the same in the optical microscope are found in starch granules within plants, in polythene bags and in sections of diseased brain tissue. Athene Donald explores structural similarities between different assemblies of polym....

99.9% of the visible material in the universe is made of quarks and yet we know surprisingly little about them. Professor Davies describes how the properties of the quark are now being revealed, and the implications that this will have for our unders....

In his talk Sandu will explain this quantum non-locality and present some of the uses of non-locality for quantum information and communication - strange effects such as teleportation - and will discuss the implications of non-locality for understand....
More details | Watch nowEvery picture tells a story
We will look at the role of pictures and images in the development of science. From the first graphs and illustrated books to Molscript, the influence of the first pictures of spiral galaxies on Van Gogh's 'Starry Night', to the artistic resonances o....

Devices are now reaching the realm where individual structures are made up of only a few atoms so that quantum mechanics, the theory of the very small, is playing a crucial role. The inevitable quantum fluctuations produce noise which was initially e....
More details | Watch nowThe uses of infinity: a philosopher looks at emergent phenomena in physics
Emergence, and its contrary, reduction, are buzz-words in both physics and philosophy. Both physicists and philosophers disagree about the extent to which we can understand large-scale or complex phenomena in terms of their microscopic parts.
