## Brexit Day Blues

Posted in Biographical, Politics with tags , , , on January 31, 2020 by telescoper

Well, here we are then. It’s January 31st 2020. This morning, Facebook reminded me that exactly seven years ago today I left Cardiff University to take up a new job at Sussex University. What a strange 7 years followed! I moved to Sussex, then back to Cardiff, and then here to Maynooth in Ireland. It seems impossible, looking back, that all that happened in just seven years.

Today’s date has a much wider significance, of course. After 11pm (Irish Time) today, the United Kingdom will no longer be a member state of the European Union. Some people seem, for some reason, to think this is a good idea. I don’t, but that’s irrelevant now. It’s happening. And I don’t live in the United Kingdom any more anyway.

It has taken three and a half years since the Brexit referendum for the UK to leave. I’ve heard it said that’s been too long, but historically it usually takes a lot longer to get the British to leave. Just ask Ireland or India, for example.

Anyway, yesterday I planned how to mark the event, and came up with the following.

Dinner will comprise Irish, Spanish, Greek, Dutch, Danish and French ingredients, with Italian wine and afterwards a glass of (Portuguese) port. That’s not all the EU countries, of course, but it’s the best I could do with the available shopping time!

Musical accompaniment will be provided by Beethoven (courtesy of the RTÉ National Symphony Orchestra live from the National Concert Hall in Dublin on RTÉ Lyric FM). I was hoping to go to the concert, but I left it too late to buy a ticket and it’s sold out!

And at the appointed hour I’ll raise a glass to the EU, to everyone in the UK who is being dragged out of it against their will, to my colleagues in the UK who hate what’s happening as much as I do but haven’t had the opportunity to escape, and to all the EU citizens in the UK who have been treated so shabbily by the British Government.

Living in a country that has chosen to define itself by its contempt for foreigners is not going to be easy, and is certain to get worse when Brexit fails to deliver the sunlit uplands’ that were promised. There are very good reasons to fear for the future.

I wrote back in 2017, when it seemed that the madness of Brexit might still be halted, but I’d decided to leave Britain anyway:

The damage has already been done. The referendum campaign, followed by the callous and contemptuous attitude of the current UK Government towards EU nationals living in Britain, unleashed a sickening level of xenophobia that has made me feel like a stranger in my own country. Not everyone who voted Leave’ is a bigot, of course, but every bigot voted for Brexit and the bigots are now calling all the shots. There are many on the far right of UK politics who won’t be satisfied until we have ethnic cleansing. Even if Brexit is stopped the genie of intolerance is out of the bottle and I don’t think it well ever be put back. Brexit will also doom the National Health Service and the UK university system, and clear the way for the destruction of workers’ rights and environmental protection. The poor and the sick will suffer, while only the rich swindlers who bought the referendum result will prosper. The country in which I was born, and in which I have lived for the best part of 54 years, is no longer something of which I want to be a part.

The Me of 2020 thinks the Me of 2017 was absolutely right.

I got this today from a friend. Posted on the front door of an EU resident.

## Britain’s Potential Explained

Posted in Politics, The Universe and Stuff with tags , , , on December 14, 2019 by telescoper

As a physicist I was intrigued by the recent use by Tory election campaigners of the slogan “Unleash Britain’s Potential”, so I decided to study the matter in more detail. I am pleased to say I am now ready to report on my conclusions.

First here is a sketch of Britain’s potential, which I denote $V(r)$:

How do we interpret this potential?

Recall that the force $F(r)$ derived from $V(r)$ is given by

$F(r) = - \frac{dV(r)}{dr}$.

The gradient of this potential being negative the force is directed towards increasing values of $r$. By Newton’s Second Law this means accelerated motion to the right (i.e. in the direction of increasing isolation), accompanied by steady and irreversible decline.

Note also that the form of this potential implies that there is something completely repulsive at its origin.

I hope this clarifies the situation.

## Winter Weather Contrasts

The world-famous British weather has been pulling out all the stops over the last few days. During a short break in the proceedings yesterday I did a bit of flat-hunting in Brighton. It was a lovely bright morning, with the winter sun low in the sky making the city look absolutely beautiful. Here’s a pic I took with my Blackberry of the Palace Pier from Marine Parade…

I managed to get away at a reasonable hour after the end of the interviews and made it home to Cardiff before the snow arrived, which it eventually did around one o’clock in the morning. It’s still snowing a bit, actually, but it’s now mixed with drizzle. The slushy streets are unusually quiet. There’s not all that much in Cardiff itself, but the examinations due to start at 9am this morning were delayed until 9.30 to allow students and staff extra time to get to the various venues. The main thing is that it’s very dark, with grey clouds filling the sky. Here’s another Blackberry pic, taken on my walk into work this morning..

The contrast with Brighton yesterday is considerable, except for the temperature. Bright and dry in Brighton, dark and damp in Cardiff and cold in both.

Still, at least the “red snow alert” broadcast by the BBC came to nothing. This lot is definitely white.

## No Cox please, we’re British…

The final episode of the BBC television series Wonders of the Universe was broadcast this weekend. Apparently it’s been incredibly popular, winning huge plaudits for its presenter Brian Cox, and perhaps inspiring the next generation of budding cosmologists the way Carl Sagan did thirty-odd years ago with his series Cosmos.

Grumpy old cosmologists (i.e. people like myself) who have watched it are a bit baffled by the peculiar choices of location – seemingly chosen simply in order to be expensive, without any relevance to the topic being discussed – the intrusive (and rather ghastly) music, and the personality cult generated by the constant focus on the dreamy-eyed presenter. But of course the series wasn’t made for people like us, so we’ve got no right to complain. If he does a great job getting the younger generation interested in science, then that’s enough for me. I can always watch Miss Marple on the other side instead.

But walking into work this morning I suddenly realised the real reason why I don’t really like Wonders of the Universe. It’s got nothing to do with the things I mentioned above. It’s because it’s just not British enough.

I’m not saying that Brian Cox isn’t British. Obviously he is. Although I do quibble with him being labelled as a “northerner”. Actually, he’s from Manchester. The North is in fact that part of England that extends southwards from the Scottish border to the Tyne. The Midlands start with Gateshead and include Yorkshire, Manchester and Liverpool and all those places whose inhabitants wish they were from the North, but aren’t really hard enough.

Anyway, I just put that bit in to inform non-British readers of this blog about the facts of UK geography. It’s not really relevant to the main point of the piece.

The problem with Wonders of the Universe is betrayed by its title. The word “wonders” suggests that the Universe is wonder-ful, or even, in a word which has cropped up in the series a few times, “awesome”. No authentic British person, and certainly not one who’s forty-something, would ever use the word “awesome” without being paid a lot of money to do so. It just doesn’t ring true.

I reckon it doesn’t do to be too impressed by anything on TV these days (especially if its accompanied by awful music), but there is a particularly good reason for not being taken in by all this talk about “Wonders”, and that is that the Universe is basically a load of rubbish.

Take this thing, for example.

It’s a galaxy (the Andromeda Nebula, M31, to be precise). We live in a similar article, in fact. Of course it looks quite pretty on the surface, but when you look at them with a physicist’s eye galaxies are really not all they’re cracked up to be.

We live in a relatively crowded part of our galaxy on a small planet orbiting a fairly insignificant star called the Sun. Now you’ve got me started on the Sun. I know it supplies the Earth with all its energy, but it does so pretty badly, all things considered. The Sun only radiates a fraction of a milliwatt per kilogram. That’s hopeless! Pound for pound, a human being radiates more than a thousand times as much. All in all, stars are drastically overrated: bloated, wasteful, inefficient and  not even slightly awesome. They’re only noticeable because they’re big. And we all know that size shouldn’t really matter.

But even in what purports to be an interesting neighbourhood of our Galaxy, the nearest star is 4.5 light years from the Sun. To get that in perspective, imagine the Sun is the size of a golfball. On the same scale, where is the nearest star?

The answer to that will probably surprise you, as it does my students when I give this example in lectures. The answer is, in fact, on the order of a thousand kilometres away. That’s the distance from Cardiff to, say, Munich. What a dull landscape our Galaxy possesses. In between one little golf ball in Wales and another one in Germany there’s nothing of any interest at all, just a featureless incomprehensible void not worthy of the most perfunctory second thought; it’s usually called France.

So galaxies aren’t dazzlingly beautiful jewels of the heavens. They’re flimsy, insubstantial things more like the cheap tat you can find on QVC. What’s worse is that they’re also full of a grubby mixture of soot and dust. Indeed, some are so filthy that you can hardly see any stars at all. Somebody needs to give the Universe a good clean. I suppose you just can’t get the help these days.

And then there’s the Big Bang. Well, I don’t need to go on about that because I’ve already posted about it. Suffice to say that the Big Bang wasn’t anywhere near as Big as you’ve been led to believe. The volume was between about 115 and 120 decibels. Quite loud, but many rock concerts are louder. Very disappointing. If I’d been in charge I would have put on something much more spectacular.

In any case the Big Bang happened a very long time ago. The Universe is now a cold and desolate place, lit by a few feeble stars and warmed only by the fading glow of the heat given off when it was all so much younger and more exciting. It’s as if we inhabit a shabby downmarket retirement home, warmed only by the feeble radiation given off by a puny electric fire as we occupy ourselves as best we can until Armageddon comes.

No, the Universe isn’t wonderful at all. In fact, it’s basically a bit crummy. It’s only superficially impressive because it’s quite large, and it doesn’t do to be impressed by things just because they are large. That would be vulgar.

Digression: I just remembered a story about a loudmouthed Texan who owned a big ranch and who was visiting the English countryside on holiday. Chatting to locals in the village pub he boasted that it took him several days to drive around his ranch. A farmer replied “Yes. I used to have a car like that.”

We British just don’t like showy things. It’s in our genes. We’re fundamentally a rather drab and dowdy race. We don’t really enjoy being astonished either. We prefer things we can find fault with over things that intimidate us with their splendour. We’re much more likely to tut disapprovingly than stare open-mouthed in amazement at something that seems pointlessly ostentatious. If pushed, we might even write a letter of complaint to the Council.

Ultimately, however, the fact is that whatever we think about it, we’re stuck with it. Just like the trains, the government and the weather. Nothing we can do about it, so we might as well just soldier on. That’s the British way.

So you can rest assured that none of this Wonders of the Universe stuff will distract us for long from getting on with the important things in life, such as watching Coronation Street.
