An Engineer and a soar point with Pterosaurs

Colin Palmer, an engineer engaged in research on the aerodynamics of pterosaurs at the University of Bristol, has shown that the creatures were predominantly adapted to slow speed flight; too slow and flexible to use, or survive in, the stormy winds of some oceans, such as the albatross does in the southern oceans

Pterosaur wings had variable geometry and that, combined with their slow flight enabled them to land very gently, reducing the chance of damage to their thin bones. This goes a long way to explaining how pterosaurs became the largest flying creatures ever known, with a wingspan up to 10m across.

Colin Palmer said: “Pterosaur wings were adapted to a low-speed flight regime that minimizes sink rate. This regime is unsuited to marine style dynamic soaring adopted by many seabirds which requires high flight speed coupled with high aerodynamic efficiency, but is well suited to thermal/slope soaring. The low sink rate would have allowed pterosaurs to use the relatively weak thermal lift found over the sea.


“Since the bones of pterosaurs were thin-walled and thus highly susceptible to impact damage, the low-speed landing capability would have made an important contribution to avoiding injury and so helped to enable pterosaurs to attain much larger sizes than extant birds. The trade-off would have been an extreme vulnerability to strong winds and turbulence, both in flight and on the ground, like that experienced by modern-day paragliders.”

Palmer constructed models of pterosaur wing sections from thin curved sheets of epoxy resin/ carbon fibre composite, those sections then being tested in a wind tunnel. From those test the two dimensional characteristics of pterosaur wings were characterised fort he first time. This showed that the creatures were considerably less aerodynamically efficient and were capable of flying at lower speeds than previously thought.

Colin Palmer, trained as an engineer, originally in ship science and has over forty years of industrial experience. His interest in the propulsion of sailing vessels led to a study of the performance of thin aerofoil’s and low speed aerodynamics. He is now applying that knowledge and experience to the analysis of vertebrate flight, focusing on large pterosaurs for his PhD. His approach uses a combination of wind tunnel and vortex-lattice theoretical modeling to understand how pterosaur wings performed. More sophisticated aerodynamic analysis, using computational fluid dynamics, is to follow with the intention of providing enough information to create a free-flying model of a pterosaur.

The story reminds me of that of a particular type of dinosaur that was thought to live in marshes so that its body partially floated, due to its body structure, particularly its legs, being unable to bear its full weight. Sometime in the 1960s, or 1970s, an engineer carried out structural calculations to show that the creature’s skeletal structure was indeed capable of bearing its weight. Oddly, as I recall, the person concerned was an electrical engineer at the University of Reading. In a sense, not so odd as engineers have a good understanding of each other’s disciplines; my first year at Brunel University was a common one for all engineers; mechanical, electrical and production engineering. Either way both stories are a good example of why such matters should be investigated by other than just scientists.

Colin Palmer’s paper “Flight in slow motion: aerodynamics of the pterosaur wing” is in the Proceedings of the Royal Society B at rspb.royalsocietypublishing.org/content/early/2009/12/01/rspb.2009.1899.abstract.

Stephen Hawking says universe not created by God

Stephen Hawking has, apparently, come to the conclusion that the universe had no creator, though that notion, is, of course, based on physics; “Stephen Hawking says universe not created by God”, The Guardian, 2nd September 2010 (http://www.guardian.co.uk/science/2010/sep/02/stephen-hawking-big-bang-creator)

In his 1988 book “A Brief history of Time”, there was at least an indication that Hawking’s understanding might not be limited to just the physical, particularly when he wrote, “If we discover a complete theory, it would be the ultimate triumph of human reason - for then we should know the mind of God”

That Hawking’s understanding does not go beyond the physical is apparent from the article, as well as elsewhere. The Guardian article quotes Hawking as saying, "The fact that we human beings – who are ourselves mere collections of fundamental particles of nature – have been able to come this close to an understanding of the laws governing us and our universe is a great triumph."

Many of us are well aware that we are far more than “mere collections of fundamental particles of nature”, as is the rest of the physical universe for that matter; we are not limited to just our physical senses, which gives us a distinct advantage over almost all mainstream scientists, including Stephen Hawking.

As Hawking’s knowledge and understanding is limited to the physical, so must be his conclusions. Eminent though his work is, it is based on partial knowledge.

However, even with physical world limitations in understanding, there is still the matter of logic in that the so-called “laws” of physics are based on physical observation and have no particular bearing on what there was before the physical, putting aside the slight matter of time being as illusory as the physical world itself. Although the idea that the “Origin” of everything we know is all there is, time dose not exist and physical reality is complete illusion is difficult to grasp, it seems less so than the notion that the whole of the “real” physical universe suddenly appeared, totally spontaneously out of absolutely nothing. Once the knowledge and some experience of the vastness of creation, of which only the physical is a very small part, such understandings become easier to accept.

The other aspect is the matter of design. The title of Stephen Hawking's new book, co-written with Caltech Physicist Leonard Mlodinow, is “The Grand Design”.

Design is part of engineering, as is science, when the engineer deems science to be useful. Design is not science and is not a rational subject, it is art and irrational. Scientists may endeavour to investigate design, with their limited tools and limited understanding; they may have their own opinions on it. However, they do not, in general, have either the expertise, or qualifications, to pass any meaningful comment on design, other than from the very limited scientific perspective. Therefore, from the design point of view, the opinions of Stephen Hawking and his co-author are irrelevant, at a minimum mostly so.

These days it is not easy to find somewhere away from the light pollution of towns and cities to see a clear night sky. I remember a night, back in the 1960s, at a firework party on the beach at Holland-on-sea in Essex, adjacent to Clacton-on Sea where we lived. At one stage during the evening, I lay on the beach, below the cliff, looking out to sea, up at a clear, cloudless sky. Even what could be seen with just the naked eye more or less, screamed “Design?” In latter years I learned far more about design and began to see far more than the physical. Scientists in general, let alone physicists, often have no idea just how little they know, or, pursuing their current paths, will ever know.

Of web sites, computer gremlins and a dud Acer laptop

Towards the end of a couple of weeks in which I finally obtained a refund on the failed Acer computer bought from “At your Fingertips in Leigh Park, I had problems connecting to my web sites to update them after something of a lull in activity.

Obtaining the refund was a relief, though had taken several weeks, several E-mails and a letter, a few consultations with trading Standards, plus Jo having her say, in no uncertain terms, while we were in the shop. Oddly, not much more than a minute after we got there, Cecilia Harding took a ‘phone call that turned out to be, apparently, from Anthony, her supplier, it being, for some reason, crucial that he agreed to supply a replacement computer to sell, as new, so that she would not lose out financially, not up to her to settle with me, a customer, and take it up with her supplier afterwards; completely at odds with Trading Standards interpretation of the Law in which they specialise; odd. Even odder was Anthony phoning a minute or two after Jo and I arrived, unannounced at het shop. My comment at the time was
“Your computer supplier must be more psychic than I am!”

After a further exchange of E-mails I was able to recover my £485 a few days later, on the following Wednesday, travelling over there with Fedor, to return the loan computer, which I had long before stopped using for fear that would give out as well.

The Hewlett Packard laptop I had already purchased from Currys, in Havant, was, at £400, cheaper, of a higher specification than the Acer computer, plus being a new one, compared suspicions on the vintage of the Acer computer after we looked it up online.

Over the weekend and early this week I went back to updating my web sites then came across a linking problem, again. The home version of the FTP programme I had used for many months refused to set up and link, as did my backup one, initially. Finally I managed to update several diary pages as well as the ones on the Second Hayling Island Bridge following an article a couple of weeks ago by Elise Brewerton in “The News” (Portsmouth), “Campaigners are hoping to get funding for a second Hayling bridge to make it safer for cyclists and pedestrians to cross to the island”.

On top of that I had “borrowed” a photo of the Aberfeldy bridge, with an acknowledgement of the source, which the Haying Island one would have followed on from if Havant Borough Council had been co-operative, only to realise that it would not appear on the Hayling Island Second Bridge page of my RLK Associates web site because it was a GIF image rather than JPEG image. That is something I have to sort out quickly in order to have it ready before sending a large circulation E-mail about the bridge that could have been had Havant Borough Council not ignored, obstructed.

The Sushi, the Stew and the Failed Computer

Last Sunday, Mother’s Day, we went to our daughter’s house in Chichester, as we had the previous Sunday, the weekend when they moved into the house. On both occasions we had a very pleasant day. I had been over on the first Saturday, when they moved in; Fedor had come with me to the “At You Fingertips” shop in the Greywell Centre, Leigh Park, to try to help me retrieve my money for the failed Acer Extensa laptop computer.

On the first of those two Sundays, while Emma and I went to fetch bed from a friend’s house, Fedor had put together a meal of sushi, his favourite and well deserved after all his efforts during the house moving. Unfortunately, somehow, it was knocked off of the table, the plate breaking on the stone floor and the sushi ruined by shards of crockery.

The following day I had returned home, after visiting clients, to find Jo ad made one of her very good stews. With my plate of stew on the worktop in the kitchen, I open a cupboard to get a wineglass, there being some wine left over from the weekend. Somehow, I contrived to knock the glass against the cupboard, or somehow otherwise drop it, for the glass to bounce on the worktop and break on the floor. Clearing up quickly and pouring wine into another glass, I took the meal into another room and sat down to eat. I had only taken one mouthful when I saw two pieces of glass ion the edge of the pallet. Obviously, the glass had started to break when it hit the worktop, before landing on the floor. So, my meal was ruined by shards of glass in it, at least potentially and not worth the risk, though Jo had made plenty, enough for two days, so all was not lost.

It was peculiar to have two such similar incidents twenty-four hours apart, the only connection being that Fedor, being a computer consultant, had offered to come with me to a shop where I had bought a laptop computer, sometime previously, the computer had failed, so had the first repair, and I was having problems getting my money back.

The computer was purchased from At Your Fingertips, in Greywell Precinct, Leigh Park at the end of September 2009. It began to show signs of instability during November and failed completely by the end of the month; it kept going blue screen, “crash dump to disc”.

I agreed to the computer being repaired, though there was additional delay due to the shop owner, Cecilia Harding, being away due to illness. The computer came back from Acer, with, apparently, a new motherboard and a clean bill of health, though, when I started it, in the shop, it went blue screen, “crash dump to disc”. Cecilia Harding suggested I take it home for Christmas and try it, see if it settled down, otherwise bring it back afterwards.

The computer was no better after Christmas, Fedor said from what I told him about it, that it was a memory problem, and wondered whether the computer was an up to date model. After Christmas I accept the offer of a loan computer while we waited for a response from Acer about the supposed repair, matters being delayed due to Acers laggardly, to put it mildly, response and Cecelia Harding going on holiday.

There turned out to be additional complications and Emma suggested the obvious, ask for my money back, which was not refused but starting to get somewhat involved. I came across a Hampshire County Council trading Standards Officer at a Havant Borough 50+ Forum Coffee morning, when I called in at the Beacon Centre, in the Meridian Centre, Havant, early in February. She confirmed that Trading Standards Law was that, if a product failed in the first six months, it was deemed to be a failure at time of manufacture and a refund was due. When I, later, ‘phoned the number she advised me to contact, Consumer Direct on 08454 040506, the adviser who answered the call was of precisely the same view.

I had already begun to wonder about the stability and reliability of the loan computer, particularly being the same make and model, so I bought a Hewlett Packard laptop computer, from Currys in Havant. I had been to a PC World Store in Sussex immediately beforehand but, whichever PC World I went to Currys was closer and owned by the same holding company. Ironically, we had problems with Curry’s relating to both a fridge and a freezer during the previous several weeks but it was always down to their delivery people, those in the shop being very helpful; as was the case with Rick when I went in for the computer. The choice of the Hewlett Packard was decided by the specification and the offer price.

The loan computer was stripped of my files and software, though most of my files were on an external hard disc anyway, and returned to its box to await resolution of the situation with “At Your Fingertips”.

When he next visited us, Fedor pronounced the Hewlett Packard computer to be a good purchase, an up to date model with a good specification. He carried out an online search for the Extensa model of computer with which I had problems but could find out little about it in regard to the U.K. though did so on Eastern European websites, apparently known for memory problems, which fitted with his original diagnosis of the problem with the one I had purchased.

A couple of weeks ago I read an article in the Daily mail, about a couple who had purchased a laptop computer from a Comet Store, only to have it fail and Comet to decline a refund, at least until they essentially “camped” outside the store with a placard. In a way I can understand such reluctance but it is not good business, certainly in the long run.

When we went to “At Your Fingertips” in Leigh Park last Saturday, the shop was closed, though I was certain it did open on Saturdays; presumably that is a new development. The next time I go there the number of visits will definitely enter double figures, all in regard to one computer.

The Great Big Business Debate, The Rose Bowl, Eastleigh, Hampshire

While talking to the people on the Business Link Hampshire stand at the Chamber of Commerce meeting at the end of January, I saw some leaflets for free seminars at the Rose Bowl, Hampshire County Cricket Ground, on 3rd and 4th March. I went to those events, which were free, expecting it to consist of seminars with a few exhibitors present; it turned out to be somewhat the reverse, mainly exhibitors with the seminars tucked away in rooms under the main stand.

I did not go to all of the seminars, just a couple over the two days, though found some of the exhibitors useful.

What also transpired was that Business Link Hampshire is being taking over by SERCO, or, at least, that is the company that has been awarded the new contract, there begin dissatisfaction with the performance of Business Link Hampshire in recent years.

When I went to ask someone on the Business Link Hampshire Stand about the potential new circumstances under SERCO the person I approached turned out, from his name badge, to be Chas Morrison. I had heard of him many years before, when David Bartlett had encouraged me back to Hampshire from Business Link Sussex in 2004. I had heard Chas Morrison might be helpful from my point of view though was never allowed to meet him or anyone else.

Although I mentioned that recommendation to Chas, he did not seem to think he could have helped, then added that I should have received a letter from Business Link Hampshire about my circumstances with them, probably from Jonathan Morris, the Director. I said I had never received a letter and that it may well have gone the same way as the E-mail I was supposed to have received from Sarah Anderson that I had never been able to find on my Email program, no matter what I searched under. Chas asked for my address in case it had been sent to the wrong one and made a note. The conversation went not much further than that.

No letter ever came, though I did not expect it to; the whole of Business Link Wessex is being taken over in April and, presumably, revamped; it certainly needs to be.

In contrast I had some potentially useful conversations with other people and have heard from a few of them since.

Business in Havant, in Hampshire, and David Willetts’ book “The Pinch”

On the Monday afternoon, I spent a while at the Havant Borough 50+ Forum at Havant Civic Offices. Among the subjects that came up, one involved problems with obtaining replies to letters written to Havant Borough Councillors and Hampshire County Councillors, as well as to Council Officers. None of that was any great surprise; I was well used to problems of that type, particularly with Havant Borough Council, to the extent that I routinely published all correspondence with Havant Borough Council, whether by letter of E-mail, on the Internet. I mentioned some of my problems with Business Link Hampshire, saying that I had found public funded bodies in general, including the Councils, well out of reach as far as obtaining any redress are concerned. We pay those who use public funds but most seem beyond any control other than that they choose to exercise themselves.

While in Havant, on the Tuesday, I tried to find Julie Gallagher, of Hampshire Trading Standards, with whom I had a conversation at the Havant Borough 50+ Forum coffee morning in February, principally about the faulty computer I had bought at a small shop in Havant. It was at the same meeting that I had appraised County Councillor Ann Buckley, of the Liberal Democrats, about my problems with Business Link Hampshire discriminating against me, the County Councillor being somewhat taken aback by that, let alone my views on the atrocious level of business support in Hampshire; effectively, if anyone decides to come to Hampshire with their business, or develop one in the County, they should ensure that they keep all of their out of Hampshire, lines of communication, advice, finance and publicity open, join the Chambers of Commerce and smaller organisation such as Southern entrepreneurs but assume that all other organisations are useless, or hostile.

Julie Gallagher was not there but I had a very useful conversation with other representatives of Hampshire County Council, including, Trading Standards, who had some tables set up in the Meridian Centre. Mostly, the conversations I had were about the problems I was having with the shop where I had bought the faulty computer. However, I took the opportunity to confirm what I suspected, that organisation like Business Link Hampshire were outside the jurisdiction of trading Standards and similar, as problems with them were a business and civil matter rather than a criminal matter. On the other hand, I did find out something about the Havant Borough Council employee who had claimed to be a Member of the Institution of Electrical Engineers, as it was then, by including MIEE on his business card, though that membership, it transpired had lapsed some twenty years earlier; nowadays that is definitely a criminal offence and likely was then, though will need some double checking. However, none of the several people I informed about that deception knew that, apparently, including Councillors, Council Officers, or members of the supervising Board of the Borough Partnership, such as a College Principal and the Business Link representative.

It was suggested that I speak to people in the Economic Development Office of Hampshire County Council, particularly about the situation with Business Link Hampshire. It was more likely that I would need to find alternative avenues to business development.

What was particularly amusing, at least in the black humour sense, so do, if you are a budding entrepreneur coming to Hampshire, do remember to bring that brand of humour with you, was that David Willetts, Member of parliament for Havant, had just brought out a book, entitled “The Pinch”, Atlantic Books; it is about the “baby-boomer” generation, of which I am one, making money out of the younger generations but not doing much to give, put, any back. The irony is that, since the 1990s, I have been trying to do just that but Havant Borough Council wrecked my project and five years work, David Willetts, who had never helped anyway, said that it was a dispute between Havant Borough Council and myself, and that he could, therefore, not intervene; I still have the letter. So Havant Council prevented me contributing to local business, putting anything back from my generation and David Willetts could do nothing about it, yet David Willetts’ book criticises my generation for not contributing.

There was irony on Tuesday in the form of Mac’s Cartoon in the Daily Mail. The cartoon involved two men, hanging by chains, being whipped by a mostly naked woman in boots. Above and on the door was “Madam Whiplash (Sado-Masochist) Specialist in Prolonged Torture. Impaled on a bed of nails was a newspaper with the headline, “Opinion Poll Shock”, a reference to news stories about the apparent collapse in support for the Conservative Party as we approach a General Election. Well, if Mac regards life under the current labour Government as torture, with which I do not necessarily violently disagree, he should try life in Hampshire in general and Havant in particular, especially business life.

Business Link Hampshire – Beyond Prediction Confirmed – The Call That Never Came

Business Link Hampshire – Beyond Prediction Confirmed – The Call That Never Came

In preparation for the expected ‘phone call, from Nick Keogh, at 10.30 a.m., I collected together the material I had researched on the Internet the previous evening, computer diary notes I had printed off, an A4 pad and my telephone notebook. The A4 sheets were put in a ring binder and all were taken upstairs to my large desk with the old computer and telephone.

One of the documents that I downloaded and printed off was a Candidate Brief for applicants for the post of Managing Director of WSX Enterprise. It was of interest because it laid out the business Link Philosophy, which just happened to be the way it had been conveyed to me by others, was as I understood it but was not as practiced by Business Link Hampshire, at least not as far as I was concerned, or some other people I have met over the years, though those were before Jonathan Morris’ tenure as Managing Director of Business Link Hampshire.

For example, the note contained the following:

“Today’s business Link service is provided through three key elements:

I – Information
D – Diagnosis
B – Brokerage

Information is available primarily through telephone and web based support together with events. Diagnosis may be undertaken through those same points of contact but often requires a face to face intervention from a Business Link Adviser at a clinic or at the business premises.”

It was relevant to my forthcoming telephone conversation as telephone support was not particularly appropriate; there was relevant material I actually needed to show Nick Keogh, or whoever else I spoke to. The situation was also a far cry from the supposed up to four face to face, one to one, meetings a year to which I was supposed to be entitled, along with other Business Link customers, of course.

By 10.35 p.m. I was ready and busied myself on the computer, which is the one I use for E-mails at present, while I waited. Time passed and nothing happened, no ‘phone call, not by 11 o’clock, or anytime afterwards. Jo returned from her hair appointment just before 11.30 a.m. and I had still not received the promised ‘phone call.

Jo has a Membership Card for Havant Garden Centre, Wyvale in Bartons Road, Havant, and had received a two for one meal offer in the Garden Centre Restaurant. As out granddaughter was coming the following day and I was otherwise occupied in the later part of the week, today was our last day to use it, so we decided to do just that.

I ‘phoned business Link Hampshire, at 11.40 a.m., intending to ask for Sarah Anderson and query the missed telephone call from Nick Keogh. All I got was an answering service with the usual “You call is very important to us”; you need a wry, to black, sense of humour if you ever bring your business to Hampshire, though that is not just down to the local Business Link but most of the publicly funded business support in Hampshire as a whole. The glaring exceptions who are friendly and helpful are the Chambers of Commerce and Southern Entrepreneurs, plus their friends, of course.

I left a message to say that I had not received a call from nick Keogh, as promised, plus, of course, my phone number.

Jo and I went to Wyvale Garden Centre and had a pleasant enough lunch, though, unfortunately, they were not really geared up for the number of people who responded their meal offer, so, it was quite a long wait. Of the meals on offer, I opted for fish and chips, with mushy peas, though I prefer garden peas. At least it was better than I have had at Fuller’s pubs where the portion mushy peas is smaller than the dollop of tartar sauce and the chips are of the chunky variety. Wyvale would have been preferable to Fuller’s at the normal price; at the offer price they easily beat Fuller’s.

One of the other diners thought the Garden centre was not as good as it was, though job and I were of a different opinion. The restaurant is not quite as good as it used to be, the relatively high prices not helping, at least for several items; £3-50 to £4-00 for a slice of cake is a bit much to say the least. However, the surroundings are pleasant and the revamp, restocking of the Garden Centre has gone well.

On returning home I, immediately, checked the answering machine. There was nothing from Business Link, nor for the rest of the day.

During the afternoon, while job was out at afternoon tea with her friends, I got on with some research and writing. During that time I checked the statistics on my BlogSpot Blog. I was fascinated to notice a surge of visitors from Fareham, where Business Link Hampshire has its main Office; no coincidence, there had been visits from Business Link Hampshire. Those statistics were for the were only for yesterday and the Blog Post I put up last Sunday, 21st February, unless they caught my Monday evening Post early this morning.

I presumed that had something to do with me not receiving the promised ‘phone call from Nick Keogh, though they might have had the courtesy to ‘phone me and tell me it was off, postponed, or whatever, and given some sort of reason.

In the mid to late 1990s, before I was “blanked” by Business Link Hampshire, I had an advisor come to my house. He was on time to the minute. He took a pride in being on time and told me he had arrived ten minutes earlier and been waiting in his car over the road until the appointed time. How things change. If Business Link Hampshire was as in those days, as I found Business Link Sussex was and with whom I should have stayed, I would have brought a considerable amount of engineering business to the area, let alone the tourism side that my advisers are sure is worth so much, as were Business Link Sussex.

On the basis of the figures we have worked on, Hampshire and part of Sussex has lost £800m to £1bn pounds worth of business, over the last decade, compared with what would have been; it could be a little les, it could be a great deal more but should never have been lost at all.

The logic of the above is that, as long as I am blocked, Hampshire loses of the order of £100m per year in tourism income.

Why do public funded organisations, decline, year after year, to assist in bringing that level of business to their own region?

Do you really want to bring your business to Hampshire?!

Apart from other matters, on which I am working, I really will have to finalise the last fraction of a percent of the manuscript of “Remembering Lorelei” and let it go. I have been apprehensive about riding two publicity eruptions at once, one from the contest of the book, the other due to other matter, the Hampshire Business Link matter only being on the periphery of that. I am getting over the apprehension to the extent that I am increasing my presence on the Internet.

That is something else to bear in mind about Hampshire, you will need to use the Internet, or have connections outside the County if you wish to make sure that your voice is heard; the usual channels are poor to blocked, or, at lest, severely compromised.

My Web Sites are abroad anyway, or were last time I checked (a very appropriate current under the circumstances), though having a very good computer consultant as a son-in-law, who happens to be Russian, with family in the Baltic States and Russia, means that I could have them moved further afield if absolutely necessary; courage in the upper echelons of Hampshire is not very great as it is, let alone, perhaps, needing to contemplate falling foul of Russian Oligarchs, along with the possibility of polonium in their cups of tea.
