"For me science isn't a subject, it's a perspective. There are fascinating scientific aspects to everything from ancient history to the latest gadgets, outer space to interior decorating; and each week on The Material World we try to reflect the excitement, ideas, uncertainties, collisions and collaborations as science continues its never-ending voyage into the unknown".

Explore The Material World with the
Insect Perception
By looking at insects and measuring how they react to the world, we can not only get a better understanding of their biology, but can use this understanding to come up with potential solutions to real world problems – like helping cars avoid crashes.
Quentin is joined by Dr Claire Rind, an invertebrate neurobiologist from Newcastle University, and Dr Barbara Webb, a Perceptual Systems specialist from Edinburgh University.Ìý
They will explain what they've learnt about locusts, crickets and stick-insects, and how they're applying this knowledge to build silicon chips and robots.
Leap Seconds
At the end of this year an extra second known as a leap second,will be added to the length of the final day.
This is to correct the imbalance between the irregular rotation of the earth and the time scales we now use.
Dr Mike Hapgood from the Royal Astronomical Society explains why astronomers need timescales coordinated with the movements of the planets and Peter Whibberley from Britain's National Physics Laboratory discusses where our modern time comes from and why its now out of step with the rotation of the earth.
