Am I a dog? Vote Now

April 22, 2014

When I wasn’t trying to solve the fiendishly difficult Easter Clue Hunt my kids set for us, I spent a pleasant hour or two re-discovering the original wiki, started by Ward Cunningham in 1995. It still feels fun and anarchic and useful. Another day I will start a rant on what is and isn’t a wiki .. but meanwhile … one thing that struck me is that the community policy is Real Names Please. This seems to run counter to standard Internet sociology. What many people love about the Internet is that nobody knows you are a dog. On the other hand, maybe hiding behind anonymity is what leads to the nastier sides of the internet, like trolling. I note that I just made a couple of wikipedia links there. Now the folks that edit wikipedia are by and large a sane and well behaved community, but most usernames have almost no information, or little that tells you whether to trust this particular editor. I can see that one wants to avoid things getting personal, but its far too easy to make sock-puppets.

My instinct is that openness and transparency is good. I always sign my referees reports. (So if you just got a mean one that you suspect is me, it isn’t!!) On the other hand, from various experiences of friends and colleagues, I am well aware that sometimes you need privacy. And of course we need the possibility to blow that whistle without the secret police knocking on the door etc. But how common is all that? Enough. Lets do a poll thingy. Which of these is closest to your opinion?

 


The Truth is Out There … isn’t it?

April 17, 2014

Its disconcerting reading/watching the news from Ukraine. Not just because of the fear of decades of war to come, but the temptation to slide into relativism. Statements and stories from various quarters vary from the vaguely inconsistent to the baldly contradictory. Its tempting to think “well, they are all lying”, or “hmm.. it all depends on your point of view”. You slide down that slope and pretty soon there is no truth. We can’t let that happen. The truth is out there somewhere. Its just hard to extract from the filtered messages. As scientists, our philosophical stance is that we must be personally sceptical; you should not trust authority blindly. That’s all very well but I ain’t going to Kharkiv to make my own observations. I have to trust somebody don’t I? But who? In descending order of reliability, I guess its (1) The Guardian and the BBC (2) Our own governments (3) The Ukrainian government (4) The Russian government (5) My mate Kevin who is usually down the Dog and Ferret on a Friday, and (6) The Daily Mail.

Mind you, some days science is just as hard. I mean research, the process of uncovering new truths. The truth is out there, but its hard work to find. There are no tablets of stone. You’ve been working on something for months, but every so often you wake up in a sweat thinking oh crap it could all be wrong. Suppose X is going on instead of Y? (Radio loops versus inflationary polarisation anyone?) The philosophy of science doesn’t help. Most scientists claim to be Popperians. You can never prove, you can only falsify. All models are provisional. But its such a small step from there to “all truth is provisional”. Somehow we have to cling on to the belief that there IS a definite truth; its just that we can never have it.

A further problem is the same one we get in trying to understand Ukraine: the human filter. We can’t make all our own measurements. We have to read other people’s papers, go to conferences, and so forth. But we are all human; chasing our careers; making our pitch; following fashions; squabbling with rivals. This doesn’t mean we are not sceptical and rational; we are. But the messages are filtered through biology.

Our biology filtering a truth that is out there is essentially the message of much of Eastern mysticism and Buddhism. I have long been fascinated by where mysticism chimes with science, and where it jars. Definitely some of each. I am sitting through a MOOC on Buddhism and Modern Psychology which is quite fun. (Partly of course in mentally preparing myself for my upcoming AstroTech MOOC. Scarily soon. Gulp.) Anyway…  Zen holds that at least in principle once the biases and illusions have been stripped, you can actually personally and directly perceive the truth. Satori. Unexcelled Complete Awakening.

Boy. I’d just love a kind of mini-Satori on the structure of quasars.


Concrete Science Epiphanies

April 9, 2014

The title is a kinda cultural reference to Musique Concrete, don’t you know. Maybe should be read in French.  Sea-onss kon-krett. Pretentious, Moi?

Anyhoo. I have always loved that moment when Jane Public looks through a real telescope and sees the rings of Saturn. Suddenly its real. Not on TV. Seen with her own eyes. There is a physical context. She had to walk up some stairs to the roof, queue up, bend at an awkward angle, and squint. Mental processing is good, but physicality is also good. It helps the scientific understanding, and it has a separate cultural impact which has its own importance. Its a kind of epiphany, an awakening.

I encountered two more such epiphanies yesterday. Here in Edinbrr its Science Festival time. (In Edinburgh, if you miss a Festival, don’t worry. There will be another one along in a minute.)  During the day I donned my STFC tee-shirt and helped out at the STFC roadshow, Seeing The Universe In All Its Light. This has all sorts of groovy things, but the bit I loved best is dead simple. We had a bunch of TV remote controls and pointed them at people’s camera phones. You can see the IR beam, which you can’t see with your naked eye. People almost gasp. There are invisible things in the Universe, but they are really there. You don’t need a million pound device. I can see it with with my own phone.

Wind forward to the evening, where I was part of the SCART Connection, a strange event that presented the results of pairing up scientists from the School of Physics and Astronomy with artists from the Edinburgh College of Art to see what they would come up with. This involved microscopic pictures of sludge crystals, sculptures of Ice-2,  Fibonacci spirals, a social soundscape project, and yours truly pontificating about cosmic violence to the accompaniment of electronic music by a local composer.  All very weird and wonderful. One thing that struck me was people’s reactions to a movie of those tiny sludge crystals. You could see them jiggling – Brownian motion in action. When told that this was caused by buffeting by atoms, their eyes bulged. Atoms? I can see them in a movie made by a guy from the Art College? Wooaahh.



Restart Miscellany

March 26, 2014

Some chums complained I have written no blog posts for about eight million years. I blame teaching. Anyway. Lets see. How do you do this thing? Scrapes off rust. Here are a few bits.

(1) At last the STFC Programmatic Review emerges!!! Get it here. I have tried to wade through it, but it looks like all the interesting bits are [redacted]. I encountered one or two cynics who claimed most of it was about the process rather than the results. Unfair. I would say its no more than 40%. About another 40% is generic RCUK Boilerplate.

(2) Research Fish. Don’t even start me.

(3) George Fraser died. This was a real shock and a terrible loss to X-ray astronomy. But he has the most astonishing swan song. Here is his incredibly careful and potentially crucial paper which claims a detection of the signal of solar axions interacting with the Earth’s magnetic field.

(4) The other reason I have been a tad busy is that I have been writing and filming a MOOC with me old mate Catherine H. It’s almost ready for show time : April 28th. You can tell your Auntie to sign up here.

(5) Seeing yourself on film, especially as the free bus pass approaches, is a tad disconcerting. I seem to be perfecting the scrawny old lizard look, whereas I am expecting myself to look vaguely like Charles Manson.  Sorry, off on a 1970s nostalgia kick, as a result of watching this documentary about Mike Oldfield and the making of Tubular Bells. This made it pretty clear (if it wasn’t already) that he was inspired by Terry Riley. Rainbow in Curved Air still amazes me. Here is a yewtoob version with groovy astropix. I think the gaudy artist’s quasar at 5mins in is from an ESO press release I was involved in. Enjoy.


Deadlines. We love ‘em

January 5, 2014

Happy New Year all. Virtual Handshake.

Just discovered a groovy new web comic called Toothpaste for Dinner thanks to Tweeter @Mariancall via @CatherineQ . Well, its new to me anyway. This one is The Creative Process and will cause both giggles and nods from anybody who does anything creative which involves a deadline. This includes writing a paper or submitting a proposal…

We all love deadlines. The usual joke is “I love the whooshing noise as they go past me” which is tres amusant, but the real problem is that we tend to meet them by the skin of our teeth and let them destroy our sanity. As in aforelinked cartoon. (NB WordPress confirms my creativity. In the edit box every neologism is underlined in red. Bizarrely, this is true of “WordPress”. Anyway. Yes. Where was I?)

I have noticed a consistent pattern, especially coming up to observing runs.

  1. Start work nice and early, in a relaxed manner.
  2. Two weeks somehow drifts by.
  3. Make a plan, organise work into sections.
  4. This isn’t really working and time is passing. Getting somewhat nervous. Realise what you need is a priority list of tasks. Start working down from the top in a firm manner.
  5. The first task is half done and there is a few days to go. Getting distinctly twitchy. Miss coffee break and grab sandwich lunch but still hard to concentrate.
  6. Your flight is day after tomorrow. Feeling of desperation building. Suddenly realise got this list thing wrong. Start working up from the bottom crossing off things that aren’t essential.
  7. Flight is tomorrow. Half list crossed off from bottom. Panic starting. Go back to top and fiercely ask of each item – right, will it be a disaster if I don’t do this?
  8. Six pm in your office. Standing in middle of room unable to move because pulled in multiple directions, and muttering “not physically possible … not physically possible..”
  9. Midnight. Suddenly think “screw it, thats good enough”. Immense feeling of relief washes over you and you to go to bed.
  10. Catch flight, have perfectly good observing run etc. Possibly a few things have to be improvised.

Of course, that last minute improvising thing is a bit tricky when making ESO style Observing Blocks. For the benefit of any ESO staff that may be reading this blog I should of course clarify that I always make OBs in a calm, efficient and timely manner, with no errors. Hem.


Book fever

December 13, 2013

I am terribly excited because my book just came out. Three years in gestation, but finally got there. Its called “Astronomical Measurement – a Concise Guide”, its published by Springer, and it even has a Kindle version. I am not expecting you all to rush out and buy it, because like most textbooks it is horribly expensive – 26p a page as Mike Watson pointed out. You will appreciate that the price was not chosen by me…

Career-wise, I think maybe finishing a book ranks third after finishing a thesis (btw, well done Jack!) and seeing my first research paper come out, but pretty groovy nonetheless. I was expecting a warm glow for a day or two. But what took me pleasantly by surprise was the very positive reactions from many friends, colleagues, and distant rellies. I guess I was expecting that most people would just think “err yeah ok, thats what academics do isn’t it, write textbooks? I expect you give some lectures too.” Or perhaps the younger ones would be thinking “oh, a book, how quaint, do people still do those?”.

Through most of my life books were very important to people. Its not just the stories. Its the physical presence. A book-lined room was what we dreamed of. The smell of a new book is wonderful. I love picking up an old book in a dusty second hand bookshop and finding it signed “To Eric, Christmas 1938″. A new friend walks into your room and goes straight to your shelves to see what kind of person you are, and a conversation starts.

Well now of course the future of the physical book is unclear, along with the physical music album and perhaps the physical lecture course. (I am halfway through filming a MOOC …) But its not even clear that eBooks will survive. What I mean is, when all the material you need is dispersed through many web pages, all indexable and searchable, why do you need to package material into 300 page chunks? Shouldn’t content diffuse and spread and mingle? Part of the appeal of a book has always been the heft. Never mind the quality, feel the width. But once that is gone, why do you need so many dumb consecutive words, as opposed to a complex hyperlinked reality?
