Tibetan singing bowls and WAVE PATTERNS

Interesting article in BBC news today: Tibetan singing bowls give up their chaotic secrets

Ceremonial Tibetan “singing bowls” are beginning to give up their secrets.

 

The water-filled bowls, when rubbed with a leather-wrapped mallet, exhibit a lively dance of water droplets as they emit a haunting sound.

 

Now slow-motion video has unveiled just what occurs in the bowls; droplets can actually bounce on the water’s surface.

 

A report in the journal Nonlinearity mathematically analyses the effect and could shed light on other fluid processes, such as fuel injection.

 

At the heart of the phenomenon are what are known as Faraday waves, which arise when a fluid such as water vibrates, constrained by a closed boundary such as the edge of a singing bowl.

 

As the frequency of the rubbing reaches that at which the bowl naturally vibrates, the bowl’s edge begins rhythmically to change shape, from one slightly oval shape into another.

 

The energy of this shape-shifting partly transfers to the water, in which a range of interesting patterns can arise as the intensity of the rubbing increases.

 

But at a certain point the water becomes unstable – and a fizzing display of droplets and chaotic waves results.

 

Ron Eglash on African fractals

Interesting talk on TED on Fractals. In this clip he talks about Fractals in African villages. Just shows how ubiquitous these patterns are in our cultures…..

ARE WE LIVING IN A HOLOGRAM?

Great article covering the holographic principle on http://news.discovery.com

As the Human Body Field is composed of intersecting fields causing interferences patterns – this may also be thought of in terms of a hologram also. Read an abstract here or go to the website for more details and video..

Do you ever get those days when you question reality? One scientist has gone a step further; he is currently building an experiment that will hopefully answer whether or not we all exist as a result of a universal hologram.

‘Fractalist’ Benoît Mandelbrot dies

We are NES are fascinated by the Fractal nature of the Universe. As a tribute to Mandelbrot, who died last week, take a look at this article posted in the NewScientist:

And also the interview on the excellent TED website:

Benoît Mandelbrot, who died a month shy of his 86^th birthday on Thursday, wanted to be remembered as the founding father of fractal geometry – the branch of mathematics that perceives the hidden order in nature.
