How does a transistor work? Our lives depend on this device. When I mentioned to people that I was doing a video on transistors, they would say "as in a transistor radio?" Yes! That's exactly what I mean, but it goes so much deeper than that. After the transistor was invented in 1947 one of the first available consumer technologies it was applied to was radios, so they could be made portable and higher quality. Hence the line in 'Brown-eyed Girl' - "going down to the old mine with a transistor radio."
But more important to our lives today, the transistor made possible the microcomputer revolution, and hence the Internet, and also TVs, mobile phones, fancy washing machines, dishwashers, calculators, satellites, projectors etc. etc. A transistor is based on semiconductor material, usually silicon, which is 'doped' with impurities to carefully change its electrical properties. These n and p-type semiconductors are then put together in different configurations to achieve a desired electrical result. And in the case of the transistor, this is to make a tiny electrical switch. These switches are then connected together to perform computations, store information, and basically make everything electrical work intelligently.

A quantum computer works in a totally different way from a classical computer. Quantum bits or 'qubits' can exist in a superposition state of both zero and one simultaneously. This means that a set of two qubits can be in a superposition of four states, which therefore require four numbers to uniquely identify the state. So the amount of information stored in N qubits is two to the power of N classical bits.

So what motivates these two scientists to get out of bed and pursue this research? How much of a difference can they make, if the rice makes it to the paddock? What other issues need to be considered.

Soon these nanoscale security devices could replace holograms. They are many times more reflective than holograms, and although the structures are smaller scale, they are lower aspect ratio and therefore easy to manufacture in bulk.

Two plant scientists take you into their world as we explore the genetics controlling the cell wall's production of Beta Glucan and its role as a soluble fibre in human health. Their aim is to increase the levels of Beta Glucan in wheat and rice to improve human gut health, and it ain't easy and it might end up using controversial transgenic technologies, should other breeding options fail and they decide to take that path.
It's the biggest technology challenge since the information superhighway and it is revolutionising science. So, what IS Nanotechnology?
This video offers an introductory overview of Nanotechnology - exploring the science and processes behind it, its applications in the material world, and its potential to solve global environmental, health, and medical problems. It also reviews consumer concerns and regulatory challenges.
The video aims to increase awareness and understanding of these still emerging technologies and the issues they raise.
