Bell Damaged Brain

If I’m not getting serious brain damage I should be — and yes, more than normal, even for me. Not to mention ringing in the ears. I’ve just had my mind completely blown away. I’ve been listening to a CD of handbells; change ringing on handbells. I know not everyone gets change ringing (or even bells) and it is a peculiarly English eccentricity. But if you line bells in general, handbells in particular or change ringing, then hunt out Change Ringing on Handbells issued on CD by Saydisc (CD-SDL310).

I had this on vinyl many years ago and recently discovered that Saydisc had eventually issued it on CD. I’d forgotten how incredible it is. It has seriously done my head in. Although I get the principle I can’t get my (mathematical and logical) brain round change ringing at the best of times but certainly not done on handbells and at the speed with which these guys manage it so faultlessly. Maybe the logic is the problem?

The CD is available from Amazon UK, Amazon.com or direct from Saydisc themselves. It is just incredible!

And there’s an interesting, albeit scientifically slanted, introduction to church bells and bellringing over at Cocktail Party Physics.

This week’s self-portrait: 52 Weeks 31/52 (2008 week 39).

This is the collection of metal I wear permenantly; this scan was the first time they have all been removed in years — even the last couple of times I’ve had operations I’ve kept my wedding ring (middle right) on (but taped over).

LHC Turned On — Earth Survives

So this morning scientists turned on the Large Hadron Collider at CERN. And Earth has survived. Of course it bloody has! The flaming machine hasn’t done anything yet!

As I understand it all the scientists have done so far is to turn on the power and inject the first packet of protons into the collider ring. That was never going to do any damage, even supposing damage is likely.

So what happened to these oh so destructive black holes the naysayers think the LHC will produce? Well before that might happen, the scientists have to get a proton beam circulating in both directions (not just one as they’ve done today); then focus the beams so they collide; and then do it at a high enough energy. That is many weeks, even months, away. This is a gradual process if doing things one step at a time and gradually ramping up the power. To quote CERN’s press release:

Starting up a major new particle accelerator takes much more than flipping a switch. Thousands of individual elements have to work in harmony, timings have to be synchronized to under a billionth of a second, and beams finer than a human hair have to be brought into head-on collision. Today’s success puts a tick next to the first of those steps, and over the next few weeks, as the LHC’s operators gain experience and confidence with the new machine, the machine’s acceleration systems will be brought into play, and the beams will be brought into collision to allow the research programme to begin.

Once colliding beams have been established, there will be a period of measurement and calibration for the LHC’s four major experiments, and new results could start to appear in around a year.

So don’t expect Armageddon for a year or so, and only then if the LHC doesn’t turn out to be a white elephant!

Zen Mischievous Moments #143

Yet another timely contribution from the “Feedback” column in this week’s New Scientist

Saddle saw

MOST surprising paper title of the week has to be “Cutting off the nose to save the penis”. This article, by Steven Schrader, Michael Breitenstein and Brian Lowe appears in the August issue of The Journal of Sexual Medicine. What could it possibly be about? The online journal Physorg.com’s report on the article makes things a little clearer: “No-nose bicycle saddles improve penile sensation and erectile function in bicycling police officers.”

It transpires that the traditional bicycle saddle, with its protruding nose, can cause deleterious health effects such as erectile dysfunction and groin numbness. A study of 90 bicycling police officers before and after using noseless bicycle saddles for six months found “significant improvements in penile tactile sensation” and “significant increases in erectile function”. Irwin Goldstein, editor-in-chief of the journal, found the article so rousing that he wrote an accompanying editorial entitled “The A, B, C’s of The Journal of Sexual Medicine: Awareness, Bicycle Seats, and Choices”.

You wouldn’t believe it if you hadn’t read it here first.

Science Catch-up

I originally started off the previous post intending to write this one. So, having been diverted, here is the post I’d intended to write …

Having been “under the cosh” recently I’ve missed writing about a number of science items which have caught my eye. This is by way of a quick update on some of them.

Food Production & Agriculture
I’ve blogged a number of times about the need for a major restructuring of world-wide agriculture (see here, here and here). New Scientist on 14 June carried an article and an editorial on this subject. Sadly, being part of the “mainstream science establishment” (my term)they don’t get the need for restructuring. They see the solution only in terms of improved varieties, increased production and a decrease in food prices, with all the sterility that implies. They’re unable to see the problem in terms of overproduction of animal protein and a reduction in useful farmland due to poor methods and bio-fuel production. All very sad.

Don’t Blame it all on the Gods
The same issue of New Scientist – it was an especially interesting issue – carried a short article with the above title. I’ll let the introduction speak for itself …

Once phenomena that inspired fear and foreboding, lunar and solar eclipses can now be predicted down to the second, forecast centuries into the future, and “hindcast” centuries into the past. The person who started us down the path from superstition to understanding has been called the “Einstein of the 5th century BC”, and was known to his contemporaries as “The Mind”. He went on trial for his impious notions, was banished from his adopted home, but nevertheless influenced generations of later scholars. He was Anaxagoras, a native of Ionia in what is now Turkey, and the first great philosopher to live in Athens. Now this little-known scholar is being seen by some as the earliest known practitioner of the scientific method.

Worth searching out if you’re interested in the history of science or the Ancient Greeks.

America’s Abortion Scandal
This is the title of the third article I’ve picked from 14 June New Scientist. In the article Pratima Gupta, a (female) practicing obstetrician-gynaecologist, argues against the prevailing belief amongst US medics that abortion is always psychologically damaging for the woman. Gupta sees no evidence for this and rails against “personal moral beliefs trumping scientific evidence [and even] individuals’ personal beliefs”. What’s worse is that there appears to be covert censorship making abortion something which cannot be researched or discussed. All very interesting when put up against the case of Republican Vice-Presidential candidate Sarah Palin whose unmarried 17-year-old daughter is pregnant, being made (as I read it) to have the child and marry the father (see here, for example).

Cut!
Finally, this time from New Scientist of 19 July, which contains an article on male circumcision; again something I’ve blogged about before (see here and here). Quite predictably there is a rumpus brewing about the medical profession’s desire for all males to be circumcised – at least in Africa and by implication world-wide – egged on by the WHO. The studies which showed such huge benefits from circumcision are being criticised for their design, for being stopped early and for their assumptions. Surveys which question people’s experience of circumcision are also highly criticised. And of course being a mainstream science journal, New Scientist totally ignore any question of human rights, abuse and mutilation. It’s about time the medical and scientific professions woke up and smelt the coffee.

And Not a Holiday in Sight

I’ve not been blogging as much as I would have liked over recent weeks. I blame the day job which has been manic especially as I’ve spent a chunk of July and most of August covering for colleagues who are on holiday.

And now summer has gone and, yet again this year, I’ve not had a holiday. Every plan we’ve made to get a break away this year (excepting our 5 days in February) has turned to dust for one reason or another. We had 2 weeks off in early June, but couldn’t get away as we couldn’t get either a cat feeder or get the little buggers into the local cattery. We were planning a trip to Sweden in late-October/early November but our work has scuppered that with important meetings etc. and the friends we were going to see are moving then.

So we’ve had to compromise and are taking a week in mid-September – though having decided where we wanted to go we’ve been unable to book anywhere, so it’s going to be another stay at home break. Still we already have a couple of away-days planned, including a trip to see my favourite aunt who has just come out of hospital after a stroke. The only problem is that if we stay at home we don’t relax properly and you always that never-ending list of jobs round your neck like an albatross.

All of which means we’ve had one 5 day break away in the last two years, mostly because of clashes caused by my work and Noreen’s – at any time one or the other of us has been tied to immovable project dates and schedules. And the medics seriously wonder why I get depressed. It’s enough to drive you mad!

Maybe we can get that Swedish break in next Spring. And plans are already afoot for Autumn 2009. By then I might have won the lottery and be retired. Well at least I can dream!

Odd Facts: Feet

Consider this fact:

Most people have an above average number of feet.

How can this be? People have two feet. Do they? Consider …

The norm for humans is to be born with two feet. So far so good. A vanishingly small number (maybe, say, 1 in a million, probably fewer) are born with 3 or more feet. But for a variety of reasons a significant number will be born with only 1 foot or even no feet. And of course some people unluckily go on to lose a foot or even both feet. I don’t know the real numbers but let’s guess, for the sake of example, that 1 in 100 people have only 1 foot and 1 in 1000 have no feet at all.

So what is the average number of feet on a human? It clearly isn’t two! Using the above figures by way of example the average number of feet is 1.988 per person. Yes that’s less than 2! But for every million people 988,999 have two feet. So it is correct to say that most people, indeed the vast majority of people, have more than the average number of feet.

Amazing what simple statistics reveal and the logic we all pass over every day!

50 Years Ago in Scientific American

Reading the latest issue of Scientific American earlier today I spotted the following two items reprinted from their September 1958 issue.

The first is from the great thinker Jacob Bronowski, who older UK readers may remember for his 1973 TV series The Ascent of Man. As usual Bronowski is right on the money:

THE CREATIVE PROCESS
The most remarkable discovery made by scientists is science itself. The discovery must be compared in importance with the invention of cave-painting and of writing. Like these earlier human creations, science is an attempt to control our surroundings by entering into them and understanding them from inside. And like them, science has surely made a critical step in human development which cannot be reversed. We cannot conceive a future society without science.

The second, equally revealing but in a different way, is from eminent physicist Freeman Dyson. While many discoveries and developments have been made in particle physics and cosmology in the last 50 years, I think this statement is still true today:

INNOVATION IN PHYSICS
My view, the skeptical one, holds that we may be as far away from an understanding of elementary particles as Newton’s successors were from quantum mechanics. Like them, we have two tremendous tasks ahead of us. One is to study and explore the mathematics of the existing theories. The existing quantum field-theories may or may not be correct, but they certainly conceal mathematical depths which will take the genius of an Euler or a Hamilton to plumb. Our second task is to press on with the exploration of the wide range of physical phenomena of which the existing theories take no account. This means pressing on with experiments in the fashionable area of particle physics. Outstanding among the areas of physics which have been left out of recent theories of elementary particles are gravitation and cosmology.
