Ignorance and Knowledge

He’s entertaining. My thought is that maybe he’s trying to be contrary for the sake of being contrary. I have some sympathy with that approach. Why should we all agree? Consensus can be a dreadfully boring state of affairs.

Rory Stewart is heralding the advantages of ignorance. Even saying that sounds mildly provocative. It’s like saying; I want to be a sensible commentator but I’m going to throw a seemingly nonsensical proposition at you.

Who is Mr Stewart? He once was an English politician. He might claim to still be one. He certainly has speaking and writing abilities that make him interesting in that role. Brexit and all the shenanigans in the Conservative Party pushed him to the margins. Outside of that narrow band of madness he’s quite mainstream.

The square jawed expression and Trump-like hands of the publicity shot must have been the photographer’s first concept[1]. The title of the radio series is a good one. From one series of long histories, I’m sure he can make many long histories. History can be as long as anyone would like to make it. For most of it, humans have been profoundly ignorant about the world and its ways.

I get the notion that the starting point for discovery of new knowledge is ignorance. It’s going too far to say that ignorance can sometimes be valuable, and knowledge harmful. Call me old-fashioned but one of our greatest human achievements is education. It’s a social call to arms. Let’s raise the life opportunities for most people by passing on knowledge.

Every succeeding generation passes on knowledge. We stand on the shoulders of giants[2]. The process that forms the words on the screen in front of me only exists because of generations of development and learning. Onward we go. Well, there was that period of the so-called “dark ages” when humanity seemed to go backwards. And with modern youth there’s the fear of the coming zombie apocalypse whereby we return to a miserable ignorance.

What this says to me is that we take for granted a daily situation that is terribly fragile. Remove the underpinning of accumulated knowledge and back we go.

I say; there’s more than one kind of ignorance. I can think of 4-types without much stress.

There’s that which we all have by nature of not being able to answer the big questions. Why are we here? What’s it all for? How did everything come into being?

There’s that which is unknowing ignorance. Where we believe we know but subsequently its discovered that what we know was wrong. On going discovery.

There’s that encapsulated in the saying about choosing not to see. It’s deliberate ignorance. When we pretend or cannot face the implications of reality.

There’s that which is part of deception. Again, it’s deliberate ignorance or to encourage ignorance. This time it’s an intentional strategy to mislead, misrepresent or do malice.

I’ll listen and learn.

Ragwort

My country knowledge is a mixed bag. Certain facts have embedded themselves in my brain from the days of my youth. That much I take for granted but there’s a lot of holes in my rural knowledge. Sue, my wife often ribs me for not knowing the name of some common bird or roadside flower. It’s the moment when I grab the phone and search for a quick answer.

I’d not been the least bit concerned about the tall, thick staked bright yellow flowers that spung up around here. Growing in clumps on scruffy ground they are certainly colourful. Small daisy like flowers in their thousands. That’s not an exaggeration as the cover of flowers is like a blanket.

For some obscure reason I didn’t know these invasive plants by name. Once I’d heard the proper name for them some recognition clicked in place. Maybe they were not prolific in the West Country of the 1970s. Strangely my mind drifted to “The Return of the Giant Hogweed[1]”. Probably one of the more ridiculous Genesis musical creations.

A fact that I didn’t know about these tall wildflowers is that they are named in a 1959 Act of Parliament[2]. One reason is that they can do damage to horses and farm animals. So, colourful they maybe, what’s a less attractive feature is they are poisonous under certain conditions.

Common Ragwort is the plant in question. It seems that Ragwort is almost impossible to eradicate. The best that can be done is to control it. Each yellow-flowered plant can produce up to 150,000 seeds. These seeds can stay dormant in the soil for up to 20 years. Ragwort is a biennial, it takes 2 years for the plant to flower. On the up-side they are the home of a wide variety of insects.

Today, the weather predictions are for an almost perfect English summer day. Blue skies and plenty of sun. A day to be making the most of the garden.

Once these plants have flowered it’s time to take drastic action. I may find myself pulling up these monsters by the roots. Fortunately, I only have a few to contend with on the edges of my garden. They are not for my compost bin. For the big green bin, the local council empties on a Monday morning.

Ragwort by Anne Stevenson

They won’t let railways alone, those yellow flowers.
They’re that remorseless joy of dereliction
darkest banks exhale like vivid breath
as bricks divide to let them root between.
How every falling place concocts their smile,
taking what’s left and making a song of it.

Electric Aviation: The Promise of Clean Flight

Electric aviation is not new. Not new at all. The engineers of the past struggled with two factors. Power and weight. A French electrically powered airship was the first aircraft to make a controlled circuit. On 9 August 1884, it flew a circular course of 8 km at a max speed of 14.5 mph. Its electric motor weighed 100 kilograms and its battery weighed 263 kilograms.

It’s not a problem to be able to distribute or use electrical power on-board an aircraft. The problem come in generating enough of it from a reliable source. Today’s “conventional” civil aircraft generate and use large amounts of electrical power. For example, the Boeing 787 has two starter/generators per engine[1]. Electrical power from the generators goes to four alternating current (AC) electrical distribution buses, where it is either sent for use as is (235 V AC) or converted for use by the aircraft systems that need it.

A revolution is taking place in electric aviation. It offers the opportunity to fly cleanly. That said, the traditional technical challenges remain the same. Power and weight. In 140-years battery technology has advanced considerably. But is that enough?

A difficulty that battery powered flying is stuck with is that at the start and at the end of a flight the batteries weigh, more or less, the same as they did from the day of their manufacture. Today’s “conventional” civil aircraft consume fuel. Thus, they are significantly lighter at the end of a flight than they are at the start. Airframes can be designed to take advantage of this fact.

One of the up sides is that a good electric motor can get to an efficiency of 80% whereas a turbo fan engine comes in at around 35%. That sound great until we look at the amount of energy we can store within a given volume. Jet fuel packs a punch. To get the same punch from an electrical battery it would likely be 15 times the size. That’s not good for a practical design. The low battery energy density coupled with the high weight of batteries means that this strategy for large aircraft needs to be put to one side for now.

A modern aircraft engine like the CFM International LEAP, can develop a max take-off thrust of over 30,000 lbf. Two of those engines can safely accelerate a Boeing 737 or Airbus A320 with ease and cruise with good economy. Thus, electrification of the propulsion of this class of aircraft is a long way off. The nearest possible future for propulsion of a B737 and A320 sized aircraft may be hydrogen based.

This explains why the drawing boards are full of small electric aircraft designs where performance demands are more modest. There’s a hope that the continuous development of battery technology will provide year on year gains. Much more than aviation alone demands that battery technology advances.

Developments in hydrogen-electric aviation are catching the headlines. Much of what has been achieved is experimental. I look forward to the day when hydrogen is not used to fill airship gas bags but becomes the life blood of transport aviation. It’s conceivable that will happen in my lifetime.

Navigating the Future

The Future’s So Bright, I Gotta Wear Shades. It’s a 1986 song title but a wonderful catchphrase. Am I going to be optimistic enough to use it on Monday 22nd July? Well, why not? Suddenly, the world looks different.

A dull and sullen presidential race in the US has flipped overnight. We’ve shed the heavy load of incompetence of the last UK government. And even France avoided a catastrophe, in the political sense. Maybe times are getting better. It’s been hard to believe the world of the 21st Century was one that was going to get better and better. With the climate crisis, pandemic, wars and narcissistic political mad people around we can be forgiven for thinking that all is not well.

As a sideline, watching the video of Timbuk 3[1] doing the song and it’s a great reminder of the leaps technology has made in four decades. Cool computer graphics of the 1980s now look ghastly. Lumpy and blocky primary colours bouncing around a cathode ray tube. A 5-year-old with cardboard cutouts could have matched the graphics.

Now, maybe some of the right-wing outliers of the political landscape will turn out to be one-hit wonders. Manufactured to rail with grievances and offering no workable solutions. Dug into a depressing victim culture. If there are cycles in politics, wouldn’t it be fantastic if we were starting an upswing in optimism. Sadly, so far the public attitudes of the first part of the 21st Century have been a chorus of gloom and doom.

The pop song is not simple one. I read it that there’s a healthy degree of irony in its words. A love of nuclear science at a time when the cold war was still raging around us may have been poking fun at optimism as much as optimism itself. Anyway, thank you P. Macdonald, wherever you are.

Square eyes looking through square glasses is an image, perhaps a warning, that one day we’d all be glued to handheld portable rectangular screens that would come to dominate our lives. Now, that prediction would have required a lot of imagination in 1986.

The future is bright. I’ll go with the contention that progressively we are turning a corner. Ok, fine it’s a more dangerous world than it ever has been but, in the spirt of the song, don’t let that get you down. We have it within our capacity to navigate through the dangers that are out there.

It would be dumbest to go with the notion that every problem has a simple fix. That at the wave of a hand wars would end. That they wouldn’t have even started if some demigod was in power. There are no modern day emperors with magical powers and a mountain of cost free answers.

A liberal future is one where positive change is possible, but we are not blind to the difficulties of making it happen. The future is bright, or it can be.

The River’s Arms

It’s now called the River’s Arms Close. A scattering of relatively new houses. That’s all that remains of a rough working public house that I knew well in my youth. Not indoors. In the bars. I never visited more than the paved courtyard outside the pub. Afterall, I am talking about me at the age of 12 or 13ish. Until now, looking it up, I’d remembered the pub as being called The Railway.

This pub was just across the road from the entrance to what was then Sturminster Newton cattle market[1]. A huge agricultural market. It was on Station Road. Even then, the railway station and its steam trains had long gone. They must have gone in 1965/66. Then a political axe fell on rural railway lines. On a Monday, the town was a busy place. That was market day.

Scruffiness was a badge of honour. Galvanised steel sheeted buildings and tatty block-built sheds were the order of the day. The feast for the eye was not the buildings, more the people. The noise was overwhelming. Smells were on the rich side too.

This comes to mind because I moved a large and heavy plastic planter containing a healthy blackcurrant bush. Green leaves and wood. My crop of blackcurrants had been eaten by birds earlier in the year. This week’s plan was to find a suitable spot in the garden to transplant the bush ready for next year.

Here’s the connection. It’s to do with fruits. Local produce. In the 1960s, to earn money of our own, my brothers and I would go blackberry picking. There were times when Somerset hedgerows were teaming with mases of blackberries. They still are in a lot of places. We’d fill to the brim used plastic containers. Recycling ice-cream containers. Trying not to squish the delicate fruit.

On market day the courtyard outside the pub would become an auction ground. People would bring local produce and miscellaneous junk in the hope of getting a fair price. Everything would be spread out over the floor outside. Fruit, veg, eggs and strange ironwork and old tools. Around lunchtime a sale would take place. Informal and unpredictable. A huddle of farmers, townsfolk and on watchers. Nevertheless, all the small items were carefully booked in and booked out. For our containers of blackberries, or later in the year field mushrooms, we’d get just less than a pound, if we were lucky. That was in “new money.”

It’s July, so we are not into that season yet. It’s creeping up on us. Fruit trees are starting to look as if they are going to produce a good crop. Blackberries are slowly forming. A time of fruitfulness is coming. That season of harvest is just over the horizon.

Exposure to markets, and their volatility, is as much a life lesson as the benefits of organic produce. In that small Dorset country town, the ebb and flow of market day were as integral to life as the water that flowed in the river. Today, much of that rhythm is history. A new rhythm is running. We go from coffee shop to posh bakery to the purveyors of expensive imports.

Our dependency on national supermarkets and large-scale logistics is mainstream. The heavy lorries that carry food are not full of local produce going to a local market. They come from remote fulfilment centres on main trunk roads. They dwarf the road traffic of the past.

It’s silly to think that we can step back. Times were rougher and cruder but there’s merit in giving thought to the better bits. Today, there’s little incentive for a boy with a recycled container full of fresh blackberries.

New Day

The UK’s recent elections saw a surge in candidates and new political forces, challenging voters to make informed choices.

We had a surfeit of manifestos that said, this is what we will do if you give us power. Today, we have a stronger commitment, in the form of a speech, saying this is what we will do now you have you given us power. You can’t say you haven’t been warned. Or more positively, at least someone is focusing on the issues that are of concern rather than the nonsense of the preceding administration.

Democracy is about choosing. For the next 5-years a choice has been made. OK, that’s assuming there’s no calamities that bring the new Labour Government to its knees.

At this moment, please give a thought to those who made that national democratic choice possible. I know, I was one of them. 4,515 candidates[1] stood for election to the UK’s Parliament in July 2024. In 2019, there were 3,327 candidates who stood in the General Election. So, this year the crop of candidates was much bigger and thus choice wider. No constituency in the UK had fewer than five candidates standing.

This crop of candidates is to fill 650 seats in the House of Commons (HoCs)[2]. That’s using the word “seat” to mean Parliamentary constituency. Which there are not on the green benches. The HoC chamber cannot accommodate all the Members of Parliament (MPs) that are elected. It’s rather a strange situation in modern times.

More candidates and more volatility. A lot of the strong political ties that people have exhibited in former generations have been broken. In future the UK’s electorate must put more effort into deciding who to vote for on polling day. We see a move in political forces that is new.

I salute you. All 3,865 candidates who have plenty of time to reflect on their experience. Yes, there were a small cohort of eccentrics, but they didn’t get the news coverage that they once did. The Official Monster Raving Loony Party raised twenty-two candidates.

Local identity did play a part. There was a Yorkshire Party, Lincolnshire Independents Lincolnshire First candidate, Portsmouth Independent Party South Devon Alliance, and a sprinkling of similar others.

Since 1985. the deposit in elections to the HoCs has been £500. This is only refunded if the election candidate gets more than 5% of the votes cast. I don’t yet know how many of the 3,865 candidates lost their deposits.

The loss of a deposit by a candidate maybe regarded as an embarrassment. I don’t think it is at all. It takes a certain kind of resolve to put yourself up in front of the electorate. Regardless of the outcome that commitment ought to be applauded. It’s certain; not free of costs in respect of the individual candidate. I’d defend having a deposit as one means of preventing abuse of the electoral system. That said, it should never be higher than it is now and maybe the threshold ought to be halved to 2.5%.

Speaking

Politics without passion is like a food without taste. The ancient Greeks sensed this a long time ago. Aristotle and his followers had a way of describing how a speaker should win over an audience. Let’s face it that’s one big part of a politicians aims.

It’s no good at all standing there and saying: we’ve got some fantastic politics, and our values are your values. If no one is listening, you can be the best thing since sliced bread and nothing much happens. I’ve seen a lot of good people who shout in the dark.

The capability to persuade an audience by whatever legal means puts politician A above politician B. It’s not just innate ability although, for those who have it, that is a great asset.

So, here’s the educational bit. It’s certainly something I keep in mind however bad at it I may be. To appeal to an audience, and thus persuade, three different spots need to be hit: logos, ethos, and pathos[1].

As a professional engineer, I know the first one of these categories well. It’s good solid sound logic. It’s the use of reason to construct an agreement. It’s the favourite of technocrats. It’s the 2 and 2 equals 4. Because of the power of logic, it tends to be elevated to the number one tool in the speaker’s toolbox. PowerPoint slide after PowerPoint slide.

The problem is that this approach doesn’t work when the audience is a general one. Brexit is a perfect example. So many of the arguments against Brexit were framed in terms of economic costs and benefits. Logical, rational, sensible and supported by evidence. As it turned out addressing the head and not the heart was not sufficient.

Next on the list of three, Ethos is all about credibility. It comes from the simple question; why should I listen to this person? Is the speaker truthful? It even comes down to simple appearance – do the look the part? Like it or not, I’m not going to be inclined to listen to a politician on a podium sporting a Micky Mouse tee-shirt, wearing clown shoes and mumbling bad poetry. There’s a normal expectation that a credible individual will be polished and professional.

And so, to the last on the list. Pathos is multifaceted. I may talk of music or poetry. Those who can speak with language that evokes strong feelings. Being able to shift the emotions of an audience by evoking beliefs and values can be extremely powerful.

This one is dangerous too. It can tap into prejudices and stir-up destructive as well as constructive passions. If we have a lesson from this electoral cycle, it’s that the overuse of emotional rhetoric in a civilised society needs to be restrained. It’s for each speaker to carefully consider how the message they are sending will be received.

Politics without empathy and passion is dull and unworkable. But exciting public passion beyond a certain point has a cost. The cry for social justice or the anger at a perceived stupidity must be recognised. Overplaying emotion for political gain. Demonising an opponent with vivid words of hate. This is path to destruction. A path to be avoided. A time to stop.

Solar farms

New Government signs off solar farms. Not everyone happy.

It would be good if we could all agree that the UK needs to recognise the importance of locally produced food and drink. There’re large environmental gains to be made by reducing the distance between production and consumption. Thousands of heavy trucks thunder up and down the inadequate road infrastructure in the UK. Colossal amounts of food waste get thrown away from supermarkets. Questionable preservatives enable supply chains to grow longer and longer. There’s are bad trends.

On a related subject, I do have a problem with proposals for large solar arrays that will take out productive farmland. However, that is by no means an objection to large solar arrays, or onshore wind farms for that matter.

It’s not as if we have always been so precious about what we do with our glorious countryside. One observation I’d make is that there has been a huge increase in the urbanisation of the countryside in my lifetime. Areas that were either wild or exclusively used for agriculture are now pony paddocks, car parks, golf courses, housing estates, out-of-town shopping warehouse, fulfillment centres[1], and bypasses. In 50-years, there’s little that remains untouched.

I’d sing “They paved paradise and put up a parking lot” if I could. We really do need to think carefully about what we industrialise and what we preserve and protect.

For me large solar arrays are in the same category as acres of poly tunnels. Both serve a fundamental purpose, and both are structure that can be relatively easily removed. Keeping the lights on and eating fresh food are both part of society’s basic needs.

So, I’m not going to raise an eyebrow at new Minister Ed Miliband approving 3 large solar arrays[2]:No shock but no blank cheque either. No jumping on a political bandwagon to condemn the immediate decision.  

It’s likely the decision was sitting on the former Conservative Minister’s desk. Is this a case of difficult decisions deliberately delayed because of an election? We may never know. It would be a bit disingenuous for such politicians to complain now. Wouldn’t it?

Let’s get it right. Failure to decarbonise our national energy system is a contribution to global warming we can’t afford to make. Long-term that global warming will impact food production.

In years to come it will be interesting to see what research flags up with respect to solar farms and biodiversity in an area. There’s some chance that the results will not be entirely negative. There’s all that sheltered and undisturbed soil under the array structures. A habitat for wildlife.

Choosing between what might seem as the lesser of two evils is often the situation a politician finds themselves in. Afterall, that’s the role they must play in a democracy. The outcome may not be popular in the short-term, but a balance must be struck.

Maybe we should reverse some of the urbanisation of the countryside. Return some little used roads to nature. Demolish unused industrial units. Put back the hedges that have been lost. Rewild one or two golf courses. It’s something to consider when building new infrastructure.

Rethinking the House of Lords: Toward a Balanced and Democratic Approach

Good to hear that there’s a prospect of House of Lords reform in next week’s Kings speech. Change is on the agenda.

It’s astonishing that “hereditary” is a valid qualification for the job as a legislator. I’ve nothing against the individuals involved. Especially those who try to do the best they can. Put all that to one side, there’s a huge gulf between what’s normal in normal life and what’s normal in the Place of Westminster. It’s time to consider merit as more important than who your parents were.

The removal of hereditary peers should be just a first step. One of the most egregious unfairnesses is that way the HoL gets topped-up with political cronies a regular basis. We’ve institutionalised political tribalism in the second chamber. Ennobling people for dubious reasons has become a habit of Prime Ministers. Making contributions to political Party funds should not be a ticket to the HoLs.

There’s the religious element too. Whereas there’s a lot to be said for a level or moral guidance to be given to Peers there’s little justification for them to have votes in the HoL. I’m not denying the important part region plays in many people’s lives. What I am saying is that the laws that affect every citizen shouldn’t be shaped by a small cohort of clerics. Two countries have religious clerics in places of legislative power, and they are UK and Iran. That doesn’t sit well with me, and no doubt most people.

One change maybe controversial given that it smacks of discrimination and that is the setting of an age threshold. If Peers are given a compulsory retirement at the age of 80, it may meet an objective of getting the overall number of Peers down. What disconcerting is the implication that beyond the age of 80 a Peer’s potential contribution is less valuable.

I don’t agree that the compulsory retirement age for the HoL should be set at the state pension age. For some people age does mark a dimming of their intellect but for others they can be as sharp as a pin. The only easy option is a fixed threshold, but it should be a temporary measure.

Ideally, the size of the HoL should be fixed. Ideally, the size of both chambers should be similar. Not just because that number line-up but because the political weight should be set closer to a balance. I do assume in this formula that every Peer is a working Peer.

It’s been pointed out that in its current state the HoL makes it the second largest political chamber in the world. It’s reached ridiculous proportions for a country of our size.

Modest changes can only be a start. There’s the real need for permanent restructuring. Parliament’s second chamber must be replaced with a democratic upper house. One model would be an elected upper house with two members elected per UK region based on current/proposed metro mayoral regions or former regions used for electing MEPs.

Even the chamber’s name must go. It’s not good that we have legislators lording over us. Those sitting on the red benches are not superior beings. They are privileged. One would hope for them to be humble given that great privilege. Afterall they should be there to serve us. To serve the country.

Uneasy

Commentating is a big industry. Every moment of every day something floats to the top of the News. To make sense of it, or to make no sense at all, talking heads sit on comfy sofas and talk. We soak it up from traditional media but increasingly from social media.

I’ve often wondered how much influence is exerted by those who commentate. They often set the context within which events are interpreted. They often act like a pack, magnifying what’s first said. They are at their best when they make something complex and messy reasonably understandable.

Could it be that Heisenberg’s uncertainty principle applies[1]? It’s impossible to measure anything without affecting it. Transformed those words that might read: It’s impossible to comment on anything without affecting it. I guess that depends on the nature of the commentary. Here, I’m hardly likely to affect anything at all but you never know.

What this all about? Well, last night I was sitting on my comfy sofa watching the BBC’s Newsnight. As it happens, the leader of the free world was being televised making a gaff that led to a sharp intake of breath. It’s human error. Nobody is gaff free. What was shocking is the choreography of the moment.

Standing next to the President of the US was Ukrainian President Volodymyr Zelensky, whose name is not all that easy to pronounce, who everyone had just committed to supporting. It makes me cringe to repeat what happened[2]. I won’t.

The commentators went into overdrive. That’s to be expected. Within minutes the follow-on illustrated the avalanche of social media piggy backing that’s on-going about Joe Biden. Let’s duck the subject of age. Regardless of that factor, errors that reverberate around the media echo chamber generate a political toxicity that sicks. It’s not fair. It’s just reality.

Age may bring wisdom, or I hope it does. What’s different now from the era during which Joe Biden accumulated his experience is the relentlessness, speed and volume of communications. Not only that but messages are distorted and twisted with great ease.

To thrive in top roles, new generation skills are essential. Being savvy to the nature of social media isn’t optional. When serious events are magnified by massive proportions and presented to a global audience there’s nowhere to hide.

With perception being pivotal in politics this is an uneasy new world we are entering. I wouldn’t be foolish enough to predict what might happen next. I’m reminded of that advice offered to tourist seeking directions ‘‘Well, if I were trying to get there, I wouldn’t start from here.’’
