New Perspectives – Is the Leaning Tower of Pisa always inclined?

Posted on by

Recently I posted about an area of research I am interested in and mentioned that we were going to Pisa to present the results at the European Health Psychology Society Annual Conference.

I jokingly asked if Psychology could help the leaning tower and we concluded that the research I was offering up for scrutiny probably wouldn’t.

However the “Inclined Tower“, as a Swiss friend calls it, offers up an obvious, and visual, comparison with some of the benefits from attending conferences.

Its actually quite unusual to learn astounding new facts at academic conferences. Most of the formats involved are just too short and the programme too crowded to allow for a long and detailed examination of new research (that’s what Journal papers are really for). In Pisa there were nearly 1,300 separate pieces of research being presented, either in 15 min oral presentations, posters, symposia, or round table discussions. And all this over 4 days [programme in pdf format].

While you may not spend a lot of of time learning new material, you are forced to look at things from new angles and applying your thoughts and feelings in new ways.  In other words from a ‘New Perspective’!

You’re exposed to the work of people with very different, though equally valid, research philosophies.You can see how they tackled similar questions but from different perspectives (sometimes wildly different).

Studies in psychology provide and require multiple perspectives to be applied in order to understanding people as individuals and as individuals in a community. Research findings and implications about the mind and mental processes as well as studies of the development and behaviour, maintenance and change of socially significant behaviour are all of importance in understand and explaining (at least in part) the world we live in and how we situate ourselves within it.

p.s. John here, I sat in on some of the presentations and there were a couple of very interesting points. Traditionally the shift change in hospitals has been seen as a vulnerability and has resulted in a culture of long shifts. Some research indicated that safety might actually be improved with more shift changes, since they were more often catching problems than causing them. It was the act of explaining what was going on to someone new, a fresh pair of eyes, that caught these oversights. Equally, they sometimes gave people the impetus to make a decision. For a start up company that’s charging along eyes on the prize, taking time out occasionally to explain that bigger picture to an impartial observer, is a huge benefit.

It was also notable the lack of technology awareness in health care messages and communications. Not just the use of social media but viral gaming, mobile data capture & evaluation, and general webbiness. As I tweeted from the conference (I was in the minority having a mobile data device with me), online avatars working from fixed scripts do not make for very convincing ‘companions’. There is a lot this community could learn from places like the Pervasive Media Studio here in Bristol and the ecosystem around them.

Supersonic cafe

Posted on by

[Disclosure: I was attending last night's Science Cafe in my role as Manager of Science City Bristol.]

At last night’s Science Cafe, a broad group of Bristolians heard about CFD, Pitch drips, carbon footprint of cows, and road spray from lorries; all from a talk about a 1,000mph rocket car!

Pitch drop experiment on Wikipedia

Pitch drop experiment on Wikipedia

Computational Fluid Dynamics is the particular research discipline of Dr Clare Wood and Dr Ben Evans from Cardiff University. Clare began with a basic introduction to CFD, some of the history of the Navier-Stokes equations and the other uses they get put to. This was where the Pitch Drop came in; an experiment started in 1930 to measure the viscosity of pitch (which looks like a solid), there have been 8 drips of pitch since then as it very slowly flows into the catching beaker. Unfortunately, no one has ever witnessed a pitch-drip, there was a technical hiccup with the video feed [requires Windows Media Player] on the last drop (28 November, 2000). Clare also talked about ‘proper’ science and using CFD to model blood flow in hearts and the bio-medical applications.

Ben then picked up the topic and began talking about the pressure waves that develop as you move from sub-sonic through to super-sonic. A major challenge is the incredible pressure that will occur around the rear wheels as the third shock wave develops. This is potentially so strong it could physically lift the back-end of the car into the air, obviously a bad thing at 1,000mph!

There’s a limit to what can be done with the mini-winglets that are being used to trim the car aerodynamically, so Ben and the CFD team are leading the engineering design changes to the rear suspension & underside to try and reduce these pressure waves to make the car safe to drive. There was some more about the research development of new CFD algorithms and the promo-video (embedded at the end of this post).

After a short break, the Q&A began. The first question was about the environmental impact of a 1,000mph rocket car with follow up comments about the 19th Century’ness of a fast car. Although this wasn’t Ben’s area of specific expertise its obviously something that comes up fairly regularly. An environmental economist (or something like that) has looked at the car, the project and worked out their carbon footprint for the whole 4 year project. Apparently it comes to around 4 cows farting for a year; now I’d never entered the term “cow fart” into Google before this morning (who would) but it seems quite a research topic, even the Telegraph are reporting it!

As to the choice of a rocket car (rather than a green car); this had been intended from the outset to be an engineering adventure. The car & the 1,000mpt target are almost incidental, the primary aim is to get children (and the young at heart) excited about science & engineering and thinking about careers in the sciences. Rockets are still exciting to young kids!

The topics moved around and one that came up was the legacy of the project, what will we have after the final run (other than a very expensive museum exhibit)? Ben explained that much of the research involved in the CFD modelling is directly transferable. The example he used was how spray is formed at the back of lorries in the rain. One of the challenges of Bloodhound is the generation of a dust spray from the wheels and shock wave, and modelling how this mix of air & particles grows and affects the car. The same physics are (they think) involved in road spray from lorries, but no one has developed a good model of how spray forms and moves around the lorry. When you drive into this spray, in overtaking for example, it can be a real safety hazard, by modelling this and proposing different designs for the lorries, they might be able to reduce this spray and improve road safety.

There were tons of other questions (about an hour’s worth), it was a really great evening. Thanks to John and At-Bristol for hosting and to Bob Foster for his Science Cafe website where I found out about the event from Bob’s Calendar.

Free Bristol

Andrew McConnochie, 30 March 2008

To a packed (and hot) Rosalind Franklin room in At-Bristol, Chris Anderson (Editor of Wire, Author of Long Tail & now Free) gave a really good overview of the premise of the “Free” economy, Fremium, marginal costs and the impact of Moore’s Law on abundance & scarcity.  That was for around 25mins, he then did a Q&A session for 30 min before retiring to sign copies of his (not free) book.

I was lucky enough to ask a question which went loosely around, in this new economy of free, what is the value of geography (Hollywood, Silicon Valley, Beijing, Bristol)? Chris answered partly by describing two companies he’s just launched. For one the Chief Technology Officer (CTO) came from MIT, for the other the CTO was online and after 6 months Chris discovered that he was a High School drop out with a self-taught knowledge of Arduino in Tijuana. Chris also talked a bit about choosing to live in a place and then finding the best talent for solving a problem, which probably isn’t in your company, City or probably even country.

On stage and in the couple minutes he spent outlining his answer, this made a degree of sense but something wasn’t quite right, and it was only on the walk home that I worked through some thoughts; hence this post (it goes on a bit, sorry).

Whilst the human brain is an undoubted marvel of flexibility and adaptability, in evolutionary terms its design is around 5,800 years old. The last major version change was about 1.5 million years ago when it tripled in size, and the last genetic upgrades were around 37,000 years ago and 5,800 years ago. However, given that the internet isn’t 50 years old yet (and probably under 30), it’s a wonder that our heads don’t just explode trying to cope.

As an aside, I’ve worked for the last few years with a company in Toronto and for a while helping them build a partnership with an organisation in Vancouver; headshifting across 8 time zones is disproportionately harder than just working a 20-hour day. Even funnier is what happens when you try to physically do what the internet allows virtually and travel around the world in 23 hours, as Jeremy Clarkson found out (with a slight cheat on the international dateline – YouTube from 8:05 onwards in particular).

The point is that we’ve evolved to be local, social creatures (see the Dunbar number) and it’s only by a design fluke that we can even begin to cope with the internet. Which brings me back to geography by way of Seth Godin, we like to be in a tribe of similar people. Of course tribes can be online but fundamentally we like to meet people in real life. Its no coincidence that most digital start-ups are around the Silicon Valley area; that’s where all the other digital start-ups are. If you want to be in movies you go to Hollywood; if you want to be in finance you go to London, etc. Of course there are thriving start-up, film and finance industries outside those locations <plug>not least Bristol which has been recognised as one of the most innovative cities globally by McKinsey & the World Economic Forum, over a quarter of the global wildlife film making originate out of Bristol and the finance sector is the largest in the UK outside London</plug>.

And perhaps that’s the value of local. You can build trusted relationships with all the key partners to build a successful business and still compete globally on the ideas & products that are generated.

In my new part-time role as Manager of Science City Bristol, I was talking this morning with Martin Coulthard about the developments of the Bristol Enterprise Network over the next few months. He was making the valid point that Science City Bristol doesn’t have a ‘neat’ strapline or twitter pitch. But I’m not sure it needs one. To get back to Chris again, in the world of free and virtually frictionless transactions, we need to find the added value of being in the Bristol / Bath city region and being into science. That might be (probably is) different for each of the many tribes in and around the area.

For a bit of fun I tried “what is a science city” as a search term; WolframAlpha was completely stumped, Google found most of the UK Science Cities but didn’t really provide an answer, and Bing didn’t really do much better. I can’t promise to develop a complete answer myself, but I do think there is some great added value to be delivered.

Thanks to Andrew Kelly for running this as part of the ongoing Festival of Ideas.

[Clarification: I booked and paid for this Festival of Ideas's talk as Managing Partner of jbsh LLP, before discussions about being the Manager of Science City Bristol; I just happened to ask a question about geography in the new economy. These are my thoughts on Chris' response.]

Uncovering Strengths and Building Resilience

Posted on by

I recently attended a Mental Health Update workshop entitled: Uncovering Strengths and Building Resilience with CBT: A four Step Model. I wasn’t sure what to expect as Cognitive Behavioural Therapy is not an area I have worked in. I think the workshop description outlines it better than I could:

Strenght and ResilienceResilient people face and manage positive and negative life events. They persist in the face of obstacles and when necessary, accept circumstances that cannot be changed. Resilience provides a buffer to protect us from psychological and physical health consequences during difficult times. Clearly, resilience is a desirable quality and yet all of us experience fluctuations in resiliency throughout our lifetime. Some people never develop resilience. Others are quite resilience but don’t recognise it; they may avoid challenges they could easily surmount. Sometimes resilience is worn down by multiple stressors and challenges.

As with a lot of psychology it seems very obvious when people say it, but it is not until it is clearly thought through and stylishly presented that it really does seem like something anyone could have said.  That is exactly what happened during this workshop. The approach covered integrated knowledge from resilience research and traditional CBT approaches.  If this is an area you practice in I would recommend Christine Padesky book (and if it’s run again the workshop), as it was clearly delivered, making it appear simple to apply the developed models. I will definitely be feeding and sharing the references and resources with my clinical psychology colleagues.  This may not be an approach we use, but as with all good ideas their are elements that I am sure I can and will use, especially in designing future research projects.

Design, faster than a bullet

Posted on by

[This is a re-post from the Bristol Design Festival blog where I'm guest blogging the festival. And updated with better graphics thanks to Mike.]

Just back from a cracking talk by Mike Turner, Senior Designer on the Bloodhound SSC project. [Full disclosure, I'm a member of the Bloodhound SSC 1K Club; everything I say is highly biased, I think this is a fantastic project to be based in Bristol. :) ]

The talk was introduced by Bob Mytton, Chair of the West of England Design Forum.

Mike began with a bit of background on his career so far, from trains to cars to JCB diggers. This last culminated with JCB’s DieselMax project, to design a diesel that would go over 350mph. Speed was definitely in Mike’s future!

Although Bloodhound is an “Engineering Adventure”, their tagline, it’s ambition is to:
1. To create a national surge in the popularity of Science Technology, Engineering and Mathematics (STEM) subjects
2. To create an iconic project requiring extreme research and technology whilst simultaneously providing the means to enable the student population to join in the adventure
3. To achieve the first 1000 mph record on land

Mike quickly moved on to his core specialty of designing the outer surface, the bit that interacts with the air flow. Beginning with the outline design concept, Mike developed a refined shape for the car. This went to the team at Swansea University that were handling the CFD work. The results from the CFD, together with the engineering structural & package development (steering, suspension, controls, Andy Green, etc) were then fed into the next design cycle with Mike.

In the Q&A afterwards Mike was quizzed on the time the CFD added to the design cycle time. When they first started each CFD run was taking a couple of weeks (to run the numbers, check them and be confident of the answers). After going public with the project they were picking up additional computing support, each run was around a day.

The main challenges are to make the whole car as strong as possible (without increasing the weight too much); as slippery as possible for a Eurofighter jet engine with a solid fuel rocket strapped to it; as stable as possible in a straight line (without being so stable that Andy can’t direct it at all); and keep it on the ground (without turning into a 1,000mph plough).

So no conflicting pressures for Andy to juggle in his design decisions!

For all the CFD modeling, I was particularly struck by the comment that Mike put up from Ron Ayers, Chief Aerodynamicist on appreciating the designer’s eye for form & proportion “if it looks right, it probably is right”.

As an aside, it was Ron’s earlier work developing the Bristol Bloodhound Surface to Air Missile that gave rise to the project code name.

The Q&A was lively with Mike fielding questions for at least half an hour and staying around for another half hour as people continued to discuss the car, the design activity, and a bunch of technical questions that demonstrated real interest and enthusiasm.

A fantastic evening, thanks to the Bristol Design Festival and West of England Design Forum for organising.
