Protest

Any study about “change” will tell you that it’s not easy. Take a few of the big social transformations that have occurred over the last six decades. I can’t point to one that just happened without a campaign or fight. Social and political change comes when momentum has built-up. Pressure is needed. Often that pressure comes in the form of protest and extensive campaigning in public.

As ever faster digital connections are becoming universal, it’s still possible to buy physical digital media. Charity shops have piles and piles of CDs and DVDs as people off-load the stuff that clutters their shelves. It’s remarkable that yesterday’s whizzy new thing has become a historic artefact so quickly[1]. In 40-years, the optical digital disk has risen and then faded into the background.

I picked up a little bit of social history in a Red Cross charity shop. It’s a series of 3 DVDs that captures a slice of the career of the well-known journalist and broadcaster Alan Whicker. Stretching over six decades of travelling around the globe it’s a great watch. The series is called “Journey of a Lifetime” and was published in 2009[2]. Although, there’s plenty that dates Whicker’s documentary style there’s no doubt that his ability to quickly summing up big changes is a masterclass.

That straightforward diction and incongruous club jacket became a trademark. It gave him a neutral camouflage so he could talk eye-to-eye with hippies, dictators, evangelists, social campaigners, film stars and dubious gurus. That’s what created so many revealing conversations that are now time stamped as emblematic of an era. I recommend viewing the Whicker’s reflections on six decades of social history. It’s a great reminder of where we have been and how learning the lessons of the past is so difficult.

Back to my initial subject – change. It’s easy to say that it’s inevitable and unrelenting but its nature is less easy to discern. Change undulates. We go forwards then we go backwards in differing amounts.

I have a theory that our social progression can be plotted like an inclined wood saw. Yes, I know. It’s the engineer in me. Look at the shape of the saw’s teeth. They go forwards, and then quickly go backwards but they always go backwards less than they go forwards. That’s how a saw’s teath cut.

This is one of my abstrat reasons why the UK Government’s most recent laws to supress public protest are as stupid as political debate can get. Resisting change is nothing new. After all, the word “conservative” has a simple commonplace meaning. When all else fails, the basic political instinct to push out laws that comfort supporters is built in. As a direction for a whole country to take, this way of working is foolish and naive.

Locking up climate change protestors is not going to fix climate change. Locking up protestors against sewage on beaches and in rivers not going to fix greedy water companies. Locking up republican protestors is not going to fix the decline in public support for the monarchy.

Using the pretext that – this is what the public want – as a cover for these policies is to show the vacuum that conservative political thinking is thrashing around in. Sadly, as I’ve said, reflection on the last six decades of conservative thinking shows regressive tendencies in abundance.

Going backwards

I find it difficult to believe anyone who gets into their sixties and says that they have never had an accident. My latest isn’t original or without minor consequence. Yesterday morning a kind nurse gave me a bandage to hold two fingers straight.

At the start of the month my gardening efforts amounted to emptying pots, replanting pots, and moving pots. I’ve got far too many pots. Plants that had not survived the winter freeze were unceremoniously sent to the compost heap. Plants that looked like the spring was bringing them back to life were given a bit of pampering.

Sitting in the shade, one large square container held a small fir tree. The tree wasn’t in the best of health but remained well worth saving. What I was unhappy about was its position on the patio out the back of the house. So, it occurred to me that it was logical to move the container to a spot where the tree might flourish in future. The large square container was made of fiberglass but had the appearance of grey slate. It had been standing unhindered in one place for well over a year.

Now, you would think an engineer, like me, would know something about friction. Or in this case stiction, that is the friction that tends to stop stationary surfaces from easily moving. There are more than two ways I could have attempted to move this heavy garden container. One was to push and the other was to pull. I opted to pull and that was my big mistake.

I crouched down and with both hands pulled hard. The container was stubborn. Again, I pulled hard. Then without warning the side of the container gave way, and I went flying. Afterwards, I wish I had paid attention to what was behind me. I hit the ground awkwardly.

When adverse events like this happen, it’s as if time momentarily slows down. Naturally, it doesn’t but it feels like an out of body experience when there’s nothing you can do to stop the inevitable happening. That split second ended with me lying on my right side with my hand extended two steps down on the patio steps. My fall was broken by my backside and my right-hand middle finger.

Oh dear, this is going to hurt – that was my first thought as I lay on the hard ground looking back at the roots of the tree I was trying to save. Second thought was – why did I do that?

Knowledge with hindsight can be a universal blight. Sure, I wouldn’t have done what I did if I’d taken the time to think more deeply about all the possible consequences linked to moving heavy objects. In this case there was only me siting on the ground painfully recounting what happened. No one to say – are you crazy? You shouldn’t have pulled that part of that container.

Accidents are a part of life. Better they be minor. Better we learn from them every time.

Working hard for the money

What goes wrong with research spending? It’s a good question to ask. In some ways research spending is like advertising spending. “Half the money I spend on advertising is wasted; the trouble is I don’t know which half.[1]” Globally billions are spent on advertising so you might say – it must be working. In fact, far more is spent on advertising than is ever available for research in the aviation and aerospace world.

Research spending is a precious asset because of its bounds. Even so, a great deal of research spending is lost on activities that deliver no or little benefit. It’s true Governments, institutions and industry don’t often put-up funds for vague and imprecise aspirations or outlandish predictions but nevertheless money goes down a sink hole on far too many occasions.

A reluctance to take tough decisions or at the other extreme of the spectrum a relish in disruption plagues research funding decision making. Bad projects can live long lives and good projects get shut down before their time. My observations are that these are some of the cases that crop-up all too often across the world.

Continuing to service infrastructure that cost a great deal to set-up. It’s the classic problem of having spent large sums of money on something and thereby the desperation to see a benefit encourages more spending. Nobody likes to admit defeat or that their original predictions were way off the mark.

Circles of virtue are difficult to address. For example, everyone wants to see a more efficient and sustainable use of valuable airspace therefore critics of spending towards that objective are not heard. That is even if substantial spending is misdirected or hopelessly optimistic.

Glamourous and sexy subjects, often in the public limelight, get a leg-up when it come to the evaluation of potential research projects. Politicians love press photographs that associate them with something that looks like a solution in the public mind. Academics are no different in that respect.

Behold unto the gurus! There’s conferences and symposiums where ideas are hammered home by persuasive speakers and charismatic thinkers. Amongst these forums there are innovative ideas but also those that get more consideration than they warrant.

Narrow focused recommendations can distort funding decision making. With the best of intent an investigation or study group might highlight a deficiency that needs work, but it sits in a distinct niche of interest. It can be a push in direction the opposite of a Pareto analysis[2].

Highlighting these points is easier than fixing the underlying problems. It’s a good start to be aware of them before pen and ink meets, and a contract is signed.

Lost nature

Looking at lines and lines of felled trees is not a pleasing sight. The world outside the car window is a sight of devastation. I understand what’s going on and we have been forewarned of it for a long time. Whatever, the junction of the A3 and M25 motorway[1] looks a dreadful mess. The scheme to turn the junction into a mini spaghetti junction is underway.

This comes on top of two news stories that display an attitude to our green spaces that is disheartening and sad. One in Sheffield[2] where the local council was criticised for deceiving the public. The other story, an overnight savaging of city trees in Plymouth[3].

I’m going to be unkind to highway engineers. The impression given is that their attitude to trees, in general, is one that sees them only as an impediment to progress. A blight that stops their beautiful drawing board schemes from rising from the dirt. The obstacles in the way of more tarmac.

Now, the M25 junction 10/A3 Wisley interchange is as ugly as hell. Even when it’s finished it’s going to be one of those places in the world where a sane person would not want to spend a minute more than necessary. Watching the seasons change from a motorway jam is a poor way to live.

The largescale initiatives there are to plant more trees are great. Unfortunately, all to often the stock of mature native trees and ancient woodlands has fallen markedly in my lifetime.

Natural events play their part too. I remember massive Elm trees that disappeared as Dutch Elm disease struck. These majestic trees can reach over 40 metres in height. A row of these huge Elms dominated the skyline of my childhood. A green wall that seemed everlasting. Sadly, millions of Elm trees have been killed in the UK over the last 40 years.

A tree produces oxygen and can absorb carbon dioxide. What could be more useful that that? We must reverse the loss of nature in the UK[4], if we are to stand any chance of addressing climate change. So, plant a tree for 2023.

Every little helps

When drawing comparisons with parts of the UK, it’s responsible to say that the town I live in, Reigate[1] in Surrey is relatively affluent. However, much debt people may be carrying, the amount purchasers are prepared to pay for houses in this town is way above the national average.

Past associations between affluence and the habit of voting Conservative in local and national elections is well established. That said, for a good half of the population in Reigate there’s no love of what the Conservatives have done over the last 12 years. In fact, I would wager that a good number of former Conservative supporters are well and truly fed-up with the never-ending deception and incompetence of that political party.

Yesterday morning, just for a short while, in the chilly air a few local people gathered on a street corner to protest. Their concerns included polluted rivers, climate crisis, cost of living crisis, real incomes falling, idiotic Government rhetoric, corrupt politics, a damaging Brexit, and the suppression of the right to protest. The public response was overwhelmingly positive. Drivers tooted their horns in support, people waved and stopped to chat.

As is perfectly reasonable, there were a small number of passers-by who disagreed with the group’s banners and posters. Most often this was a shaking of the head or a traditional English gesticulation, but in addition one or two words were voiced. That’s the heart of the matter. It mystifies me how some people can be happy with the current predicament in Britain.

The most distressing words uttered were: “What’s the choice?”

There are several ways to interpret this negative shout-out. One: it could be a cry of genuine desperation.  Two: it could be a deep reticence accepting a bad situation and a loss of hope. Three: it could be a stubborn Conservative who’d be happy regardless of the situation.

This is what those who want to see change happen have got to get to grips with this year. To bring real change about there needs to be a big collection of people who openly welcome change. That does mean embracing those who are still sitting on the fence.

It means seriously building confidence that today’s troubles can be beaten. As can be seen from this small group’s posters the list of troubles is long, so this is no simple task. Hope for the future means overturning incompetent incumbents and giving a chance to competent fresh faces. It means having honest and practical solutions ready to go. It means having a vision. 

Rebuilding Britain’s liberal democracy is the vital and urgent mission.

Turnip

Root crops come in different shapes and forms. In Britain, most of our sugar comes from sugar beets[1]. It’s weaned the country off colonial sourced sugar cane of decades ago[2]. It’s a large home-grown industry that goes on under the radar. Given recent utterances, Government Ministers may not know that it exists.

There are deep cultural themes that are associated with root crops in Britan. Some of this imagery comes from a long history of growing root crops. Some of this comes from the British war time experience of ploughing up every available space for food production. In a time of food rationing the humble turnip played a key role. The turnip, Brassica rapa L., is one of the world’s oldest cultivated vegetables. Afterall they don’t require a lot of attention and can endure hostile weather quite well.

It’s a common myth that we (the British) all eat seasonally. It was mostly the poorer people in a community who had little choice.

My own recollection is of my father unsuccessfully growing a small field of turnips. They will grow in heavy Somerset clay soil but the mess of cultivating them on land that floods is beyond a joke. Machinery gets bogged down and the harvest is more dirt than turnips. I remember that the crop made good animal feed and little else. The field was quickly retuned to a new lay of grass.

This week, Conservative Secretary of State for the Environment, Food and Rural Affairs Therese Coffey told the UK Parliament: “lot of people would be eating turnips[3]…”. This was a government statement addressing empty British supermarket shelves.

Now, I’m not about to have a downer on the poor turnip. They are a bit of an acquire taste but have meritorious qualities and are inexpensive. It’s more the silliness of the Minister’s utterance in the House of Commons that is surprising. It’s a naive exposition that casts the vital subject of food security as a comic game. The Minister doesn’t seem to have a command of her brief.

We all know that crop production can be sensitive to weather conditions throughout the growing season and at harvest. Farmers know that and live that fact. Supermarkets know that and live that fact. Both food production and distribution adapt, accordingly.

The British problem is that the cost of production has rocketed. Brexit and high energy costs have hammered farmers. Former specialisms in agriculture, like tomato production under glass, are not sufficiently supported to remain viable in current condition. In fact, tomato production is not alone in this respect.

What’s clear is that the UK’s Minister needs to get a grip. She needs to understand the nature of British agriculture and stop making foolish excuses.

High ALT

Normal commercial air traffic control doesn’t go beyond 60,000 ft in altitude. That makes sense since civil flying activities have been limited to lower altitudes. In fact, modern commercial airliners are not designed to fly above about 45,000 feet. This is a compromise based on what works commercially as much as what’s works best. Aircraft instruments are calibrated making standard assumption about the atmosphere.

For some of its flight, Concorde cruised at a height of 60,000 feet. More like a military jet, with its speed it had the capability to make use of higher altitudes.

It’s even possible to fly above 50,000 feet without an engine. The world record glider flight by AIRBUS shows it’s possible.

The Earth’s atmosphere is not uniform. It changes its characteristics with altitude. The atmosphere can be divided into five layers, as the temperature and density change. They are named: Troposphere, Stratosphere Mesosphere, Ionosphere and Exosphere. 

The Troposphere is a layer that goes from 8 kms (26,247 ft) on the poles to about 18 kms (59,055 ft) on the equator. This is the layer where weather is experienced.

On average, the Stratosphere goes up to about 40 kms (131,234 ft). The winds blows fast but they tend to be more consistent as they wrap around the globe. The lower portion of the Stratosphere is virtually isothermal (layer of constant temperature). 

A medieval English philosopher and Franciscan friar, Roger Bacon[1] figured out that the air might support a ship in the same way that water supports ships. In the 13th Century that was a nice academic conclusion but little more.

With all the current controversy surrounding high altitude balloons, that the road to flight started with balloons, could be said to be a bit ironic. It’s long been known about that balloons fly well at high altitudes but it’s a new frontier as far as commercial activity is concerned. For science, weather balloons may go up to 40 km to measure the high level winds.

Some experimental work has been done on trying to commercially use the airspace above normally civil flying. The Google Loon trials[2] are an example of an attempt to float a telecommunications platform high in the sky. These balloon trials were abandoned as difficulties proved greater than anticipated.

It’s not so easy to keep a high altitue balloon on-station.

Now, considering the news in North America, maybe high-altitude operations ought to be a matter of regulatory concern. This is not a subject that any one country can address alone.

There is some legal, regulatory and technical work[3] underway in Europe[4] but it needs to make progress. This is a subject for international collaboration.

Over the Horizon

How often does the obvious comment need to be made? It’s Sunday 11th February and the new UK Secretary of State for Science, Innovation and Technology has only been in the job for a few days.

UK Ministers Michelle Donelan latest utterance is straight out of the failed Brexit playbook. The UK is “ready to go it alone”, she says[1]. Let’s puff up our chests, money is no object, the UK doesn’t need to be part of the €95.5 billion Horizon Europe[2] programme of the EU. Or at least that’s what she and her colleagues seem to be saying.

The rather silly argument is made that the UK will work with the US, Switzerland, and Japan instead. Now, hang about, call me a bit crazy but couldn’t the UK do both?

There’s no way the UK can become a global science powerhouse without working with both the EU and the rest of the world. Well, with a few possible exceptions. Afterall, it would not be wise to be forging research links with Russia at the moment.

Partnerships and collaborations matter so much because so many great ideas are based on the work done by others.

Already the UK is seeing a decline in research students coming from Europe and China. The Home Secretary’s struggles to control migration with all the subtlety of a sledgehammer doesn’t help.

Yes, the UK has a history as an inventor and can be capable in science even if we pull up all the drawbridges but that’s incredibly limiting, commercially crazy and like throwing a damp blanket over future pioneers. Remember young talent is mobile.

I do remember the exit of UK talent that occurred in my student days (1979-82). I’d meet some of them later in my career working in aerospace companies all over the world.

Putting aside all the above, big money matters, but what matters more is opportunity.  That is fertile ground for innovation.

Contrary to UK Government Minister’s thinking this has nothing to do with de-regulation either.

Across the Atlantic we have a highly regulated country that still seems to be able to produce innovators that go on to change the world. There are more lawyers per square mile in the US than just about anywhere on Earth but that doesn’t stop that country being an incubator for ground-breaking innovation. [Says me, on my Windows PC with my iPhone charging next to my iPad.]

Today, the US Inflation Reduction Act (IRA) is going to make funding available on a gigantic scale. The UK’s cash-strapped Government can’t match this US effort even if it wanted to do so.

Europe needs to work together. The UK needs to be one of the associated countries[3] to participate in Horizon Europe. The alternative is grim.

Apprenticeships

What do you think are the reasons behind the overall decline in engineering apprenticeship starts in recent years? We are particularly interested in understanding more about supply and demand.

Image. It persists even now. In fact, the paper[1] that asks these questions has images of spanner turning. It’s so easy to pick royalty free pictures that pop-up from search engines searches. These images show mechanics in blue overalls. Don’t get me wrong, this is not the least bit disrespectful of spanner turning.

A deep cultural memory persists. It has multiple elements. You could say, in part, industrialisation, still conjures up images of dark satanic mills contrasted with grand country homes of a class of business owners. Basically, dirty, and clean as two key words.

The Victorians did a great deal to both elevate engineering personalities, like Brunel[2], but to hold them as different or apart from the upper middle-class society that the fortunate aspired to join. Those who forged the prosperity of the age had to work hard to be accepted in “society”.

Today, it makes no difference that’s it’s American, popular comedies like “The Big Bang Theory[3]” entertain us immensely but pocket the “nerd” as eccentric, peculiar and unfathomable. I admit this is attractive to a proportion of young people but maybe such shows create exclusivity rather than opening people’s eyes to possibilities.

Having Government Ministers standing=up can calling for Britan to become a version of Silicon Valley doesn’t help. Immediately, that signal is heard from those in authority, young people switch “off”. To boot, the image conquered up is a whole generation out of date. We have the Windows 95 generation telling the iPhone generation what’s the best direction to get to the 2030s.

Here’s a proposition – you must see yourself as an “engineer” to become an engineer. That can be said of a whole myriad of different professions. Each with a common stereotype. Look at it the other way. If you cant’t see yourself as a person who can shape the future, it isn’t likely you will choose engineering.

My observation is that we need to get away from too many images of activities. In other words, this is an engineer at work. This is what they do. This is what they look like. What we need to address is the touchy-feely stuff. Let’s consider how young people feel about the world they have inherited from my generation.

A high level of motivation comes from the wish to make changes and the feeling that it’s possible to make changes. That the skills picked-up as an apprentice will help you shape the future. Engineering is part of making a better world.

[My history is that of an Engineering Industry Training Board (EITB) apprentice who started work in 1976.]

Pulp

Eyes wide open in astonishment. I saw a supermarket newsstand. That’s not new. From time to time, I find it better to scan the daily headlines rather than buying a newspaper. Frankly, in the world of social media and search engines the sane and sober daily national newspapers are too expensive. They only make sense on a Sunday when there’s time to take in what they have to say.

It’s a moribund marketplace. British daily newspapers are in slow decline. Nevertheless, each title has a readership that remains loyal even if it’s declining in numbers. Before the mobile phone took so much of our attention time it was important to consider who reads the papers. As a sketch from the BBC comedy “Yes, Prime Minister” nicely put it[1].

I have an admiration for those who can transform difficult technical material into everyday language. That kind of communication skill is much needed and often undervalued. Taking simple words and sentences and telling a story that makes knowledge accessible, well that’s rare.

The newspaper headline that caught my eye was “It’s a space burp, Jim, but not as we know it.” Topped by “Earth facing solar blast as powerful as a billion nukes”.

This is wonderful example of how to turn real science into pulp and mush. I might be the only one who picked up the Daily Star, some irony there I think, and thought this thought. What a way to highlight a story about the sun. No, not The Sun but the sun that’s 93 million miles away.

There are some great people in the National Oceanic and Atmospheric Administration in the US who run a space weather prediction centre[2]. Their website is a place to go if you want to know where to see the northern lights at a particular time and place. On Monday 9 January, there was a solar flare that may have affected radio transmissions in South America. That’s useful to know if you are on a ship using High Frequency (HF) radio communications in that part of the world.

“Earth could soon be in the firing line of a massive solar storm with the power of billion hydrogen bombs” is certainly an interesting and rather scary way of putting it. What the readership of The Star should do about this suggested calamity is not explained.

The Sun is restless, powerful, and essential to life on Earth. It’s prudent to keep a watchful eye on what it does. There’s no doubt that it can cause havoc on extremely rare occasions. We are now more vulnerable than past generations given our dependence on extensive electronic communications.

The Sun runs on an 11-year cycle. I don’t think anyone knows why that happens, but it does. We are coming out of the quiet part of the cycle so there’s likely to be more reports on this subject. Solar flares, like massive earthquakes and volcanic eruptions are difficult to predict. Our ability to warn of a once in a 5000-year event is fragile.

Perhaps this story is a hopeful wish of a newspaper editor. We will put down our broken mobile phones and pick-up newsprint once again. I wonder?
