I’ve been reading Bryson’s At Home: A Short History of Private Life, and very entertaining and informative it is too. Strangely, one of the best things about it for me was that he explained, briefly and persuasively, both the rise to global stardom and the fall from global stardom of British agriculture. The rise was a lot to do with the idea of crop rotation. I remember vaguely being told about this in a prep school history class, but although I did remember the phrase “crop rotation”, I didn’t care about it or about what it made possible.
Here is Bryson’s description of this key discovery:
The discovery was merely this: land didn’t have to be rested regularly to retain its fertility. It was not the most scinitillatingof insights, but it changed the world.
Traditionally, most English farmland was divided into long strips called furlongs and each furlong was left fallow for one season in every three - sometimes one season in two - to recover its ability to produce healthy crops. This meant that in any year at least one-third of farmland stood idle. In consequence, there wasn’t sufficient feed to keep large numbers of animals alive through the winter, so landowners had no choice but to slaughter most of their stock each autumn and face a long, lean period till spring.
Then English farmers discovered something that Dutch farmers had known for a long time: if turnips, clover or one or two other suitable crops were sown on the idle fields, they miraculously refreshed the soil and produced a bounty of winter fodder into the bargain. It was the infusion of nitrogen that did it, though no one would understand that for nearly two hundred years. What was understood, and very much appreciated, was that it transformed agricultural fortunes dramatically. Moreover, because more animals lived through the winter, they produced heaps of additional manure, and these glorious, gratis ploppings enriched the soil even further.
It is hard to exaggerate what a miracle all this seemed. Before the eighteenth century, agriculture in Britain lurched from crisis to crisis. An academic named W. G. Hoskins calculated (in 1964) that between 1480 and 1700, one harvest in four was bad, and almost one in five was catastrophically bad. Now, thanks to the simple expedient of crop rotation, agriculture was able to settle into a continuous, more or less reliable prosperity. It was this long golden age that gave so much of the countryside the air of prosperous comeliness it enjoys still today, ...
The fall of British agriculture was all mixed up with refrigeration, which enabled the wide open spaces of the late nineteenth century world to make masses of food and to transport it to hungry urban mouths everywhere before it went bad. Prices fell below what the farmers of Britain (where there were no wide open spaces by global standards) could match.
This afternoon, The Guru is coming by to reconstruct God, so God (the other one) willing, I will be back in serious computing business by this evening.
When I was recently in Brittany, my hosts supplied me with a state-of-the-art laptop and a state-of-the-art internet connection. These last few days, without God (my one) and having to make do with Dawkins (my obsolete and clunky little laptop, the thing I am typing into now), I have felt less connected to the world than I did in Brittany. I am connected, after a fashion. But Dawkins is so slow and clunky that I have been doing only essentials (like finding out about England being hammered in the ODI yesterday), and checking incoming emails, and shoving anything however bad up here once every day. It’s like I’ve regressed to about 2000.
I have managed to put up a few pictures here, in God’s absence. But Dawkins’ screen makes these pictures look terrible. I am looking forward to seeing God’s version of these pictures and hope they will be greatly improved compared to what I am seeing now.
Thank God (the other one) I haven’t been depending on God (my one) for music. As I have surely explained here many times, one big reason I prefer CDs (and separate CD players scattered around my home) to all this twenty first century computerised music on a computer is that if God goes wrong, as he just has, I don’t lose music. I also have music concerts recorded off of the telly, onto DVDs, which I can play on my telly, which is likewise a completely separate set-up to God.
In general, the argument against having everything done by one great big master computer is that when something goes wrong with that master computer, everything else in your life also goes wrong, just when you may need those things not to. One of the things that willgo wrong, rather regularly, with your all-in-one master computer is when this or that particular one of its excessively numerous functions becomes seriously out of date. I mean, if it has a vacuum cleaner included, what happens if vacuum cleaners suddenly get hugely better? In Brian world, all I have to do is get another new and improved vacuum cleaner, and chuck out the old one. In all-in-one master computer world, you are stuck with your obsolete vacuum cleaner. Or, if you can, you have to break open your all-in-one master computer and fit a new vacuum cleaner, and probably also lots of other new stuff to make sure the new vacuum cleaner works, which buggers up a couple of your other functions that used to work fine but which no longer work fine. Or at all. I prefer to keep things simple, and separate.
Something rather similar applies with how to handle (the other) God. That is another arrangement you don’t want to have running the whole of your life for you either. It’s okay if you do God for some of the time and keep Him in his place, but you want scientists telling you about science, doctors about medicine, and your work colleagues about your work, and so on. If, on the other hand, absolutely everything in your life, and worse, everything in the entire world you live in, is controlled by ((your version of) the other) God, everything is very liable to go to Hell. (Aka: Separation of Church and State. Aks: don’t be a religious nutter.)
I have my own particular take on (the other) God, which is that He is made-up nonsense. But just as wise believers in (the other) God don’t let that dominate their thinking on non-God things, nor do I think that my opinions about (the other) God can explain everything else as well. These opinions merely explain the particular matter of (the other) God being made-up nonsense.
Do not, as they say, put all your eggs in one basket.
Overheard in a TV advert for sweeties:
You can’t trust atoms. They make up everything.
Talking of which, I am now reading Lee Smolin’s book about String Theory. Basic message: It’s a cult. I haven’t yet read him using that actual word, but that’s what he is saying.
I am, of course, not qualified to judge if Smolin is right, but you don’t have to be qualified to express a judgement, and I judge that Smolin is right. And the way I like to learn about new stuff is by reading arguments about it, starting with the argument that says I am right about it. Smolin is basically telling me that my ignorant prejudice that String Theory is one of the current world’s epicentres of the Higher Bollocks is right, although he is careful not to express himself as crudely as I just did, for fear of upsetting his physicist friends, and because, unlike me, he sees some merit in String Theory.
I have known that String Theory was in trouble for some time, because Big Bang Theory’s resident String Theorist, Dr Sheldon Cooper, has been having doubts about it. He wanted to switch to something else, but they said: We hired you as a String Theorist and a String Theorist you will remain.
The above link is to a blog I had not heard of before, entitled Not Even Wrong. Not Even Wrong is the title of another book I have recently obtained with has a go at String Theory. I have not yet started reading this.
It’s true. You can’t trust atoms. And grabbing both ends of one and stretching it out into a string doesn’t change that. It makes it worse.
From Stuff Matters by Mark Miodownik (pp. 80-81):
Given that literally half of the world’s structures are made from concrete, the upkeep of concrete structures represents a huge and growing effort. To make matters more difficult, many of these structures are in environments that we don’t want to have to revisit on a regular basis, such as the Oresund bridge connecting Sweden and Denmark, or the inner core of a nuclear power station. In these situations it would be ideal to find a way to allow concrete to look after itself, to engineer concrete to be self-healing. Such a concrete does now exist, and although it is in its infancy it has already been shown to work.
The story of these self-healing concretes started when scientists began to investigate the types of life forms that can survive extreme conditions. They found a type of bacterium that lives in the bottom of highly alkaline lakes formed by volcanic activity. These lakes have pH values of 9-11, which will cause burns to human skin. Previously it had been thought, not unreasonably, that no life could exist in these sulphurous ponds. But careful study revealed life to be much more tenacious than we thought. Alkaliphilic bacteria were found to be able to survive in these conditions. And it was discovered that one particular type called B. Pasteurii could excrete the mineral calcite, a constituent of concrete. These bacteria were also found to be extremely tough and able to survive dormant, encased in rock, for decades.
Self-healing concrete has these bacteria embedded inside it along with a form of starch, which acts as food for the bacteria. Under normal circumstances these bacteria remain dormant, encased by the calcium silicate hydrate fibrils. But if a crack forms, the bacteria are released from their bonds, and in the presence of water they wake up and start to look around for food. They find the starch that has been added to the concrete, and this allows them to grow and replicate. In the process they excrete the mineral calcite, a form of calcium carbonate. This calcite bonds to the concrete and starts to build up a mineral structure that spans the crack, stopping further growth of the crack and sealing it up.
It’s the sort of idea that might sound good in theory but never work in practice. But it does work. Research now shows that cracked concrete that has been prepared in this way can recover 90 per cent of its strength thanks to these bacteria. This self-healing concrete is now being developed for use in real engineering structures.
Maybe Miodownik is very good at explaining things, or maybe I am just ready to be learning this stuff. Probably both. I chose that excerpt because my average reader may not know about such things as bacteria which automatically repair concrete. But the truth is that I am almost embarrassed by how much I am reading that is new to me, or only vaguely known, as a sort of historical rumour.
I had no idea, to take just one example, who invented/discovered stainless steel, or where, or how. Now, I have a much better idea. The story is told on page 29 of this book, which I heartily recommend to all technological illiterates who would like not to be technological illiterates.
Every once in a while I hear or read about someone who sees sound, as colour, different sorts of sounds as different colours. (As you can tell from the links at the bottom of this, I just did this again, on purpose.) What the hell are these people talking about? You don’t see sound, you hear it.
But, I have learned enough of the contrasting natures and nervous systems of different people to know that claims of this sort are probably true, in the sense that this is indeed what it feels like to those making such claims, even if the claims made no sense whatever to me. (Here is another piece by me, about how different people differ, this time with respect to the notion that you (i.e. they) can decide what you (they) believe. To me, what you believe is what you actually do believe, and you can no more change it with a mere decision than you can decide to grow another foot. But other people clearly can change what they believe, in just this cavalier fashion. What they actually, deep down, think is true doesn’t seem to matter to them. To me: bewildering and bizarre. To them: obvious and commonplace.)
So anyway, back to those bizarre and bewildering people who see sounds, different sounds as different colours.
I now understand these people much better.
Because, yesterday morning, for a fleeting instant, it happened to me.
Immediately after it happened, I hastily bashed some notes into a computer file describing what I had just experienced, and that is the file that I am now typing further and more considered thoughts into now.
What happened was that I awoke, to the sound of my alarm clock. This alarm clock makes a high pitched beeping noise: beep, pause, beep, pause, beep, pause ...
And, I experienced this sound as ... white.
That is correct. I saw the sound. And the sound was just as white as the background colour of the file into which I am now typing, or the background colour of this blog posting as you are now looking at it.
I never experience sounds a colours when fully conscious. But it makes perfect sense to me that experiences I may only have during the weird moment when I am neither entirely awake nor entirely asleep, but am moving from the latter state to the former state, might be experiences that others may have much more frequently, even when fully awake. Or, fully awake by their standards.
Yesterday morning, for that fleeting, bleeping instant, some sort of weird connection was being made between my ears and the bit of brain where colours get processed and reflected upon, a place where all incoming messages are interpreted as colours no matter what they were originally, a connection that doesn’t normally occur, or perhaps which continues to occur when I am fully awake, but so weakly compared to the connections made between my ears and and the sound processing part of my brain as to be undetectable.
All I have to believe, about those strange people who see sounds as colours all the time, is that they experience what I very briefly experienced yesterday morning, but much more strongly than I did and do. This is not now hard for me to imagine, not hard at all.
A very quick skim-read of this wikipedia article about chromesthesia (which is the particular sort of synesthesia that turns sound into colour, as opposed to just something into something else) did to tell me that chromosthesia can happen particularly when you are waking up, but that could be wrong.
However, I did spot (at the other end of the chromesthesia link above) this:
However, all studies to date have reported that synesthetes and non-synesthetes alike match high pitched sounds to lighter or brighter colors and low pitched sounds to darker tones, indicating that there may be some common mechanism that underlies the associations present in normal adult brains.
So, I am not alone in associating a high pitched bleep with a very light colour, in my case the lightest colour of the lot.
A commenter on one of the climate skeptic blogs, I think at Bishop Hill, provided a link to this fascinating posting, at Coyote Blog.
The Coyote man combines three tendencies that he sees in global temperatures. First, there is a warming process that has been going on since the Little Ice Age. Second, there is a slight kink upwards in this graph, very slight, associated with recent CO2 increase. Third, there is an oscillating wave, for some reason involving a couple of acronyms. And the result is a graph that seems to fit the recent facts better than any other graph I’ve seen. Certainly better than that idiot hockey stick.
If Coyote is right about all this, and he is in fact only semi-serious about it, then the global temperature will soon be seen to be inching downwards, until about 2030, at which point it will then turn back towards relatively rapid heating, again, along the lines of what happened from circa 1970 to circa 2000. So, a few We Will Freeze years, followed by some more We Will Fry decades.
However, we’re talking tiny numbers here. None of this is remotely describable as a catastrophe, even in the long run.
Coyote says he developed this stuff six years ago. But I could find no link back to him actually saying this six years ago. Pity.
Not for the first time, I find myself wishing that I could live another two hundred years rather than for about another twenty or probably less. What will happen to global temperatures for the next century or so? How will the politics of it all play out? I’d love to live long enough to find out. But, I won’t.
This started out as a jokey posting about climate science. It ended up as yet another rumination on the process of getting old. When you are young you are going to live indefinitely. You will die, eventually. But too long into the future for this event to be distinguishable for practical purposes from never. Then, rather suddenly, that all changes.
I recently did another climate science posting at Samizdata.
I still can’t get used to the internet. I never really will. You can find all kinds of stuff out in a few seconds. You know that, and so do I know it. But, unlike (probably) you, I will never get truly used to this.
Last night, for instance, there was a TV show on about Fossils, fronted by this old Fossil Professor, and mention was made of – and a little sliver of film was shown of – a building (with lots of fossils in it) called the Royal Ontario Museum. I said, that looks like that Daniel Libeskind museum in Berlin, in the saw cuts in big blocks style. So let’s see about that Royal Ontario Museum shall we? Sure enough, that is Libeskind also.
I had imagined that the saw cut style was specifically used only for that Berlin museum, to make you wince when you look at the building, same as you do when you find out the grizzly details of what happened to all those Berlin Jews.
However, it now seems (to me) that Libeskind just likes doing saw cuts. Am I getting this wrong?
Maybe I could google that question also, and find out if anyone else agrees with the above. But that’s enough answers for one posting.
… in among all the stuff that does not.
Foster’s flaccid Gherkin used to advertise erectile dysfunction treatment. Personally, I don’t think the Gherkin looks like a penis, more like a vibrator. Certainly not a gherkin.
