"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".

The science of laughter
Charles Darwin argued that it discharges surplus tension and mental excitation. Freud claimed it helps us deal with lustful thoughts.
But what is the real reason why we laugh?
This week on Material World, Quentin Cooper finds out what happens to our body and mind when we laugh, and why some types of seizure can lead to uncontrolled outbursts.
He talks to physiologist Dr Harry Witchel, from the University of Bristol, and Dr Eduardo Jáuregui, a social psychologist from St Louis University in Madrid.
Measuring Earth from space
New technology is allowing geologists to measure the movement of the Earth's surface down to millimetres
Satellites send a pulse of radar energy from space back to our planet and measure the amount of energy reflected.
There are far reaching applications for recording earthquakes, active faults in the crust, glacial movements, volcanic activity and landslides.
Quentin Cooper talks to seismologist Dr. Chris Browitt from University of Edinburgh and Nigel Press, geologist and satellite technology expert.
The BBC will be awarding a young science broadcaster the chance to spend two weeks working with the team that brings you programmes such as MATERIAL WORLD/ LEADING EDGE.
So if you are under 25 and not working as a professional broadcaster, go to the ABSW website to find out how you can be considered for the BBC Radio Science Unit/ Association of British Science Writers Young Broadcaster of the Year Award.
