Bubbles!

This time last year, I was a lil bit stressed. The Royal Society Summer Science Exhibition was just a few days away, and we were about to pack the van….. This year, I’ve had a much easier time 🙂

NPL will be represented AGAIN this year, but this time, I’m not involved 🙂 But the stand is called

POP! The Sound of Bubbles

…. and, as you might have guessed, its all to do with bubble research.

To learn more about this bubbly topic, I interviewed my colleague Gianluca Memoli, a “bubble scientist” from NPL. We talked about bubbles, the science behind them and their amazing and wide-ranging applications. I also managed to get a sneaky preview of the POP! exhibit…… If you have a spare 20mins, you can have a listen to our piece here: http://lauriewinkless.wordpress.com/2012/06/28/bubbles/bubblesatnpl/

 

Here is some of the “blurb” from the official site:

Bubbles are everywhere – think of champagne, boiling water, inkjet printers, cleaning fluids and volcanoes. Interestingly, there is a special connection between gas bubbles and sound waves. Sound can be used to create bubbles, as happens in treatment for kidney stones, and bubbles can also alter sounds, as happens when waves crash onto the beach.

When bubbles are probed by sound, they ‘ring’ differently according to their properties and surroundings. As a result, they can be used as cost-effective medical sensors, for example for detecting cancer in the human body.

Acoustic bubble research could lead to less intrusive, cheaper, more accurate medical diagnosis and treatment. It could also lead to food which tastes better and new ways to characterise industrial processes.
