A sneak preview of some of the work I’ll be presenting on Sunday.

Below is a radio-image taken by ALMA of the “Antennae Galaxies” colliding. We have transformed the image-cube data, in which each pixel represents an electromagnetic radio spectrum, into a sonic spectrum. By clicking the image and moving your cursor around you can “play” a spectrum of the colliding galaxies.

Spend some time moving slowly around the red(redshifted) areas – there is a surprising richness to the harmonics for such a simple sonification.

Note: this loads a 62MB data-cube before displaying (still working on a compressed version) … it could take many minutes to appear if you are on a slow connection – it did take these photons 70 million years to reach us, so please be patient while they go the last few bit-miles!

To get a sense of the picture at optical wavelengths, here’s the HST image [more at National Geographic or WIRED].

As part of my ongoing work on Binary Dust, I am speaking at Heavenly Discourses on Sunday 16th October 16:45 – 18:00. PANEL: Music

I’ll be presenting new work (including sounds and pictures derived from ALMA) that my great collaborators, Andrew Newsam and Julie Freeman, have helped me with (thank you!).

Here’s the abstract of my paper. I am delighted to have been accepted – esp. as I’m one of the few/the only non-institutional presenters at the conference.

The utterance of a cosmological model?

A conjoining of languages, Acoustic Cosmology is an attempt to describe our audible worlds – a 21st century progression of the music of the spheres – a narrative of acoustic sculpture within n-dimensional space. With no intentional stance on sound as a cultural construct or phenomenology, we openly explore links between cosmology and music, using the language of mathematics and sonic art.

Building on the works Trevor Wishart and Jean-Pierre Luminet, and developed by professional astronomers and musicians, we question and connect the fabric of these non-verbal languages.

Using cosmology and sonic art as its basis, this paper will provide a journey of discovery – a basis for discussion in the junction between music and astronomy, opening up new methods of comprehending scale, connection, depth and complexity. Sound examples and visuals will be included in the presentation.

We’re all aware of the emotive language used to polarize the climate change debate.

There are, however, deeper patterns which are repeated across science as it interfaces with politics and media. These patterns have always bothered me, but they’ve never been as “important” as now.

We are entering an new era of seismic change in policy, business, society, technology, finance and our environment, on a scale and speed substantially greater than previous revolutions. The sheer complexity of these interweaving systems is staggering.

Much of this change is being driven by “climate science”, and in the communications maelstrom there is a real risk that we further alienate “science” across the board.

We need more scientists with good media training (and presenting capability) to change the way that all sciences are represented and perceived. We need more journalists with deeper science training – and the time and space to actually communicate across all media. We need to present uncertainty clearly, confidently and in a way that doesn’t impede our decision-making.

On the climate issue, there are some impossible levers to contend with;

  1. Introducing any doubt into the climate debate stops any action that might combat our human impact.
  2. Introducing “certainty” undermines our scientific method and its philosophy.

When represented in political, public and media spaces, these two levers undermine every scientific debate and lead to bad decisions.

Pascal’s Wager is often invoked, and this is entirely reasonable in this case.

It is reasonable because of what’s at stake: the risk of mass extinction events. If there is a probability that anthropogenic climate change will cause the predicted massive interventions in our ecosystem, then we have to act.

The nature of our actions must be commensurate with both the cause and the effect. The causes are many: population, production, consumption – as are the effects: war, poverty, scarcity, etc.

Our interventions will use all our means to address both cause and effect, and those actions will run deep.

Equally, we must allow science to do what it’s designed to do: measure, model, analyse and predict.

From a scientific perspective we must allow more room for theories to evolve, otherwise we’ll only prove what we’re looking for.

However, if we ignore the potential need to act, the consequences are not something anyone will want to see.

It’s not something we can fix later (for me, “geo-engineering” is not a fix, it’s a pre-infected band-aid).

Given the massive complexity of the issues, and that – really – anthropogenic climate change is only one of many “peak consumption” issues that we face, there is no way we can accurately communicate all the arguments that would lead to mass understanding.

However, the complexity issues are no different from those we face in politics. They are not solvable, but they are addressable.

We can communicate the potential outcomes, and the decisions that individuals need to make in order to impact the causes.

Ultimately it’s your personal choice.

My choice is based on my personal exposure to the science, business, data, policy, media, and broader issues around sustainability. That choice is to do my best to catalyse change as fast as I possibly can.

We all need to actively engage in improving communication, so that everyone – potentially everyone on Earth – can make informed choices about the future of the planet we inhabit.

This year is the 50th anniversary of Jodrell Bank.

Today is also a landmark day for Jodrell Bank – the whole science team are moving from on-site, to Manchester University. While this is probably very practical, I can’t help feeling sad that this unique and historic research establishment is dramatically shifting its identity.

I worked at Jodrell from 1994-1995 and thoroughly enjoyed it: 120 scientists in the middle of a field in deepest Cheshire. Remarkably “British” Science – on my first day I was shown around to one of the “workshops” (very slightly more advanced than a garden shed) where someone was building an amplifier for the main dish and cooling it to about 10 degrees Kelvin, making it one of the quietest amplifiers on Earth. In another room, someone was building their own data router, to carry data at 30 Gigabits per second,

since the best commercial ones of the time couldn’t come anywhere close

…today MERLIN‘s seven telescopes ship 30Gbps, each, to a huge computer cluster at the main facility that processes 150-200Gbps of data in real time – making it one of the most powerful computers on Earth.

The history of Jodrell Bank and the Lovell Telescope is vast: it’s first official task was to identify and track Sputnik – it was the only instrument the West had (at the time) that could do so.

Pulsars and Quasars are amongst the discoveries in which Jodrell was the catalyst. The Cosmic Microwave Background, Masers, Gravitational Lenses, and myriad others are part of the rich mixture of Radio Astronomy research.

Jodrell gets very little mention compared to other facilities, unlike its US counterpart the VLA, or the Hubble Space Telescope. The latter is particularly relevant – Jodrell has had equal or better resolution than the HST since before HST launched – and the only reason you don’t know that is because NASA have a $20m “marketing budget” to tell the world. That’s about the same as Jodrell had to upgrade the entire facility.

Jodrell was mentioned a couple of times in The Hitchhiker’s Guide to the Galaxy “… Jodrell Bank looked straight through them [Vogon spacecraft]— which was a pity because it was exactly the sort of thing they’d been looking for all these years … someone decided it was time for a nice relaxing cup of tea” – and happens to be very true: tea at 11am and 3pm was an unmissable part of the day. Everything stopped.

It was at tea that one of the longest serving members of staff was trying to recall how they’d built some of the 6-bit computers I was trying to re-interpret the data from (“now was bit 3 the weather or the telescope ID?”). I should have kept that envelope…

Last year the Lovell Telescope was nominated the UK’s greatest ‘Unsung Landmark’ in a BBC competition. This only scratches the surface. To me, Jodrell Bank is iconic of an entire country of passionate, brilliant scientists, who get little of no recognition for the spectacular work that they do. At various times, Jodrell has had to justify its existence, which is reasonable for any institution to have to do, but I believe that much of its real value is overlooked….

I am delighted that, 13 years after leaving, I will be going back to hear some of my music played at the 50th Anniversary celebrations. Amongst other things they are projecting onto the 76m Lovell dish, which should be quite spectacular – it’s at least twice the size of the largest IMAX screen. (hope the weather’s good!).
