The Power of Sound and Music

This week we're exploring the science of sound and music. We sound out the human voice, hear why we all talk differently, and probe the origins of accents and the means by which impersonators mimic their victims.  Also, we discover how a tune can act like cocaine in your brain and why, in some cultures, music can replace a lawyer!  Also, we hear what's going on in the brains of Jazz musicians as they improvise, see how hungry sharks are similar to shoppers and find out why a big brown bat needs magnetic bat-nav.  Plus, in kitchen science we discover the musical secrets of plastic bottles!

  • 41:08 - Could mediatation put you into REM sleep?

    Iím interested in meditation and Iíve noticed that when mediating or journeying with shamanic drumming that my eyes do something a bit like REM movement and Iím wondering if that has something to do with the sound or this particular sound and rhythm?

  • 41:57 - Is there such a think as Brown Noise?

    Is it true that thereís a sound that makes people want to go for a number 2? (sometimes known as the 'Brown Note')

  • 42:40 - Are wrinkles in other animals distinguising like fingerprints?

    I understand that fingerprints are very useful because they provide the ability to grip surfaces better as well as be identified. I was wondering about the wrinkles you see on animals. Do they effectively have a fingerprint pattern in the same way, specifically marine creatures...

  • 44:17 - Speed of Caves

    After spending a few days underground in a cave I became anxious about the following question. As I know soluble rocks like limestone are soluble in liquid containing CO2 which comes from the atmosphere. This takes about 30cm of rock every two millenniums. If we take into account...

I just want to say that this episode was the first one I've actually listened to... and I'm definitely coming back for more. I teach high school physics and plan to use a few clips from this show (not to mention a bunch of the kitchen science experiments) in my class when we study sound. Great show, great site, thanks a lot!

I also want to point out that I successfully identified which of the choirs was boys and which was girls. keydetpiper, Thu, 5th Nov 2009
