Discuss: Your Science Questions
« on: 14/06/2009 17:31:50 »
On this Naked Scientists Question and Answer show, we discover how storms create slow earthquakes and how a local star, Betelgeuse, could explode very soon.  We also hear of an accurate way to date pottery and explore the physics of helicopter seeds.  Plus, why hurricanes rotate in opposite directions either side of the equator, the ultimate fate of stars and how to boil your fishtank without harming the fish.  All this and in Kitchen Science we snap some spaghetti to seek the physics of pasta!

Hi guys, love the show.

When I play poker with my friends and I get a good hand, I find it hard to control my feelings. My heartbeat goes up and a vein in my neck starts to pulsate.

My friends find this easy to pick up on. Can you tell me whats happening and why? And how can I stop it?

Would safe, effective contraception count for the Science Museum's inventions that changed the future? Definitely a life transforming and life-saving invention!

Pottery can be dated with Thermoluminescence

Julie Rees-Jones asked the Naked Scientists:
Your latest podcast contained an item on using clay hydrolysis to date pottery and stated that there was no existing method for dating pottery.  

Thermoluminescence has been used for many years to date fired ceramics.  In addition hydrolysis is a chemical reaction and will therefore be affected by temperature.  To get an accurate date it needs to be known at what average temperature the pottery has been kept at.  Not always a easy thing to work out.
