I had the pleasure of meeting physicist Cyril Isenberg this week.  He gives an extraordinary range of science talks and demonstrations. 



Isaac Newton's beautiful drawing keeps coming to mind with respect to one of the projects we're working on.


Kepler's discoveries



I recently saw a brilliant and moving exhibition at the Queen's Gallery at Buckingham Palace of the photographs taken by the dedicated photographers of the expeditions of Robert Scott and Ernest Shackleton in the Antarctic nearly 100 years ago.  

I was struck by this image - Shackleton and four others leave the rest of the group (it turned out for several months) to seek help at the whaling station of South Georgia.  This poignant image shows the little reinforced boat departing - with its sides slightly raised and a cover made.  Desperate good wishes and hopes are writ large in the gestures of everyone left behind in the harsh environment of Elephant island.

Abdus Salam

I discovered this image of Abdus Salam recently in a talk by Tom Kibble and am struck by its beauty.  The text on the wall is a 16c Persian prayer - a reminder of the power of miracles provided they are initiated with hard work.

Salam - a devout muslim, saw his religion as an integral part of his work and once said:

"The Holy Quran enjoins us to reflect on the verities of Allah's created laws of nature; however, that our generation has been privileged to glimpse a part of His design is a bounty and a grace for which I render thanks with a humble heart."

In his Nobel Prize acceptance speech in 1979 , he quoted these verses from the Quran:

"Thou seest not, in the creation of the All-merciful any imperfection, return thy gaze, seest thou any fissure. Then return thy gaze, again and again. Thy gaze, comes back to thee dazzled, aweary."

and then said

"This, in effect, is the faith of all physicists; the deeper we seek, the more is our wonder excited, the more is the dazzlement for our gaze."


Joseph Wright of Derby opens in Derby

It was a pleasure to visit the newly reopened show of works in Derby this weekend.  Joseph Wright is probably most well known for his paintings depicting demonstrations of science (see last image of the orrery) during the enlightenment and his use of strong light-dark effects (chiaroscuro).  

This image of a rainbow drew my attention for the strange rendering of the colours which missed the red from the usual rainbow sequence and replaced it with more of a violet outer edge.  It left me wondering if the paint had changed during the last two hundred years or if he'd chosen to weave his own rainbow and pay less attention to nature to possibly make a better picture.  


My restorer, conservationist friend, HGW has a perspective on the missing red of the rainbow....

"Joseph did have problems with his pigments, like many 18thC British artists; and quite a few of his paintings, particularly the darker ones where he mixed bituminous substances and employed drying additives, have resulted in shrinkage of the paint layer. 18th C pigments were not as stable as 19th and later. Reds, for instance, reacted to sunlight and faded. No doubt he added the red over his sky and the fading of the red, coupled with a cooler hue beneath will give a more violet colour.  If, for instance, the blue of the sky contained a degree of 'smalt', a blue glass pigment which reacts with the oil in the medium and fades to grey, this also might give a violet hue.

Just a couple of thoughts; would need to check old Joseph's paint box to be absolutely sure!"


The way light fell.......

Have been thinking about using natural light in a new project and took this image of the wall at home and found these three remarkable images made by camera obscura techniques.  And this famous camera obscura scene from 'A Matter of Life and Death'.


More Larkin on nature

First Sight

Lambs that learn to walk in snow
When their bleating clouds the air
Meet a vast unwelcome, know
Nothing but a sunless glare.
Newly stumbling to and fro
All they find, outside the fold,
Is a wretched width of cold.

As they wait beside the ewe,
Her fleeces wetly caked, there lies
Hidden round them, waiting too,
Earth's immeasurable surprise.
They could not grasp it if they knew,
What so soon will wake and grow
Utterly unlike the snow.



Tops heel and yaw,
Sent newly spinning:
Squirm round the floor
At the beginning,
Then draw up
Like candle flames, till
They are soundless, asleep,
Moving, yet still.
So they run on,
Until, with a falter,
A flicker - soon gone -
Their pace starts to alter:
Heeling again
As if hopelessly tired
They wobble, and then
The poise we admired
Reels, clatters and sprawls,
Pathetically over.
- And what most appals
Is that tiny first shiver,
That stumble, whereby
We know beyond doubt
They have almost run out
And are starting to die.

Molecule Cooling - Optics Table

This beautiful optics table took two years to build.  It exists in the physics department basement.  Quite a few different colours (or energies) of laser light are required to cool a molecule due to the more complex energy level structures (compared with an atom) - resulting in this lovely spectacle.  The molecules are cooled to temperatures colder than outer space of less than a mK by hitting them with carefully tuned photons of light that exactly match the quantum energy levels of the molecule taking into account the doppler effect.


' scope given to the imagination' - Charles Darwin

"In calling up images of the past, I find that the plains 

of Patagonia frequently cross before my eyes; yet these

plains are pronounced by all wretched and useless. They can be

described only by negative characters; without habitations,

without water, without trees, without mountains, they support

merely a few dwarf plants. Why then, and the case is not peculiar

to myself, have those arid wastes taken so firm a hold on my

memory? Why have not the still more level, the greener and more fertile

Pampas, which are serviceable to mankind, produced an equal

impression? I can scarcely analyze these feelings; but it must

be partly owing to the free scope given to the imagination.

The plains of Patagonia are boundless, for they are scarcely

passable, and hence unknown; they bear the stamp of having lasted,

as they are now, for ages, and there appears to be no limit to

their duration during future time. If, as the ancients supposed,

the flat earth was surrounded by an impassable breadth of water,

or by deserts heated to an intolerable excess, who would not look

at these last boundaries to man's knowledge with deep but

ill-defined feelings?"

Charles Darwin.


"Science is fiction" - Jean PainlevĂ©

I have just become an admirer of the short films of Jean Painleve (1902 - 1989).  He affirmed "the superiority of reality", the "extraordinary inventiveness of Nature", over "the artifice" of traditional cinematographical scenes. He is pictured with his homemade waterproof housing for underwater photography.  Below is his short film, 'Le Vampire' where the real becomes surreal.


'This is The First Thing', Larkin and 'The Sigh', Hardy

Two poems about the passage of time and things that cannot be recaptured.  They were bought together in an email conversation. 

This is the first thing
I have understood:
Time is the echo of an axe
Within a wood.
 - Philip Larkin from 'The North Ship' collection, 1945
The Sigh
Little head against my shoulder, 
Shy at first, then somewhat bolder,
  And up eyed;
Till she, with a timid quaver,
Yielded to the kiss I gave her;
  But, she sighed.
That there mingled with her feeling
Some sad thought she was concealing
  It implied.
- Not that she had ceased to love me,
None on earth she set above me;
  But she sighed.
She could not disguise a passion,
Dread, or doubt, in weakest fasion
  If she tried:
Nothing seemed to hold us sundered,
Hearts were victors; so I wondered
  Why she sighed.
Afterwards I knew her thoroughly,
And she loved me staunchly, truly,
  Till she died;
But she never made confession
Why, at that first sweet concession,
  She had sighed.
It was in our May, remember;
And though now I near November
  And abide
Till my appointed change, unfretting,
Sometimes I sit half regretting
  That she sighed.
- Thomas Hardy

'In praise of particle physics', The Economist, 17 December 2011

In this week of economic turbulence in Europe and the glimmer of the prospect of discovering the Higgs particle, this quite beautifully written leader article in The Economist voiced my thoughts...
Higgs ahoy!
The elusive boson has probably been found.  That is a triumph for the predictive power of physics.

IN PHYSICS, the trick is often to ask a question so obvious no one else would have thought of posing it. Apples have fallen to the ground since time immemorial. It took the genius of Sir Isaac Newton to ask why. Of course, it helps if you have the mental clout to work out the answer. Fortunately, Newton did.
It was in this spirit, almost 50 years ago, that a few insightful physicists asked themselves where mass comes from. Like the tendency of apples to fall to the ground, the existence of mass is so quotidian that the idea it needs a formal explanation would never occur to most people. But it did occur to Peter Higgs, then a young researcher at Edinburgh University, and to five other scientists whom the quirks of celebrity have not treated so kindly. They, too, had the necessary mental clout. They got out their pencils and papers and scribbled down equations whose upshot was a prediction.
The reason that fundamental particles have mass, the researchers calculated, is their interaction with a previously unknown field that permeates space. This field came to be named (with no disrespect to the losers in the celebrity race) the Higgs field. Technically, it is needed to explain a phenomenon called electroweak symmetry breaking, which divides two of the fundamental forces of nature, electromagnetism and the weak nuclear force. When that division happens, a bit of leftover mathematics manifests itself as a particle. This putative particle has become known as the Higgs boson, whose possible discovery was announced to the world on December 13th (see article).
Physicists demand a level of proof that would in any other human activity (including other scientific ones) be seen as ludicrously high—that a result has only one chance in 3.5m of being wrong. The new results—from experiments done at CERN, the world’s premier particle-physics laboratory, using its multi-billion-dollar Large Hadron Collider, the LHC—do not individually come close to that threshold. What has excited physicists, though, is that they have got essentially identical results from two experiments attached to the LHC, which work in completely different ways. This coincidence makes it much more likely that they have discovered the real deal.
If they have, it would be a wonderful thing, and not just for science. Though nations no longer tremble at the feet of particle physicists—the men, and a few women, who once delivered the destructive power of the atom bomb—physics still has the power to produce awe in another way, by revealing the basic truths that underpin reality.
Model behaviour
Finding the Higgs would mark the closing of one chapter in this story. The elusive boson rounds off what has become known as the Standard Model of physics—an explanation that relies on 17 fundamental particles and three physical forces (though it stubbornly refuses to accommodate a fourth force, gravity, which is separately explained by Albert Einstein’s general theory of relativity). Much more intriguingly, the Higgs also opens another chapter of physics.
The physicists’ plan is to use the Standard Model as the foundation of a larger and more beautiful edifice called Supersymmetry. This predicts a further set of particles, the heavier partners of those already found. How much heavier, though, depends on how heavy the Higgs itself is. The results just announced suggest it is light enough for some of the predicted supersymmetric particles to be made in the LHC too.
That is a great relief to those at CERN. If the Higgs had proved much heavier than this week’s announcement implies they might have found themselves with a lot of redundant kit on their hands. Now they can start looking for the bricks of Supersymmetry, to see if it, too, resembles the physicists’ predictions. In particular, in a crossover between particle physics and cosmology, they will be trying to find out if (as the maths suggest) the lightest of the supersymmetric partner particles are the stuff of the hitherto mysterious “dark matter” whose gravity holds galaxies together.
A critique of pure reason
One of the most extraordinary things about the universe is this predictability—that it is possible to write down equations which describe what is seen, and extrapolate from them to the unseen. Newton was able to go from the behaviour of bodies falling to Earth to the mechanism that holds planets in orbit. James Clerk Maxwell’s equations of electromagnetism, derived in the mid-19th century, predicted the existence of radio waves. The atom bomb began with Einstein’s famous equation, E=mc2, which was a result derived by asking how objects would behave when travelling near the speed of light. The search for antimatter, that staple of science fiction, was the consequence of an equation about electrons which has two sets of solutions, one positive and one negative.
Eugene Wigner, one of the physicists responsible for showing, in the 1920s, the importance of symmetry to the universe (and who was thus a progenitor of Supersymmetry), described this as the “unreasonable effectiveness of mathematics”. Not all such predictions come true, of course. But the predictive power of mathematical physics—as opposed to the after-the-fact explanatory power of maths in other fields—is still extraordinary.
Some might see the hand of God in such predictability. The Higgs boson is, indeed, known to headline writers as the God particle (though the sobriquet was actually first given by a bowdlerising editor, who shortened an author’s reference to “that goddamn particle”). Others will prefer to stand in awe of a universe that they suspect began as a quantum fluctuation in pre-existing nothingness. And yes, there are calculations explaining how that could have happened, too.
Both sides, though, should be in awe not merely of the universe, but also of the men and women who have stripped, and continue to strip, that universe of its mystery—and do so without diminishing the wonder of it all. So, at a time when the future of human affairs seems particularly uncertain, a Christmas toast to the predictability of physics. 

Testing Einstein's Theory of General Relativity

Francis Everitt gave a fascinating talk yesterday at the departmental colloquium about the experimental mission - Gravity Probe B, which completed earlier this year, over forty years after its original conception. The aim of the mission was to verify Einstein's Theory of General Relativity, by investigating two extraordinary phenomena predicted by Einstein: the geodesic effect (warping of spacetime due to the Earth) and the frame dragging effect (the extent to which the earth drags its spacetime round with it). The project is a fantastic story of human vision, tenacity and imagination.

Emmy Noether - Einstein's appreciation

Emmy Noether was a great woman mathematician.  She created one of the most beautiful and profound theories showing how our most fundamental conservation laws of energy, angular momentum, linear momentum and charge can be derived from corresponding symmetries.  Here is Einstein's memorable and thought provoking tribute, published in the New York Times.

Emmy Noether

Professor Einstein Writes in Appreciation of a Fellow-Mathematician.

To the Editor of The New York Times:

The efforts of most human-beings are consumed in the struggle for their daily bread, but most of those who are, either through fortune or some special gift, relieved of this struggle are largely absorbed in further improving their worldly lot. Beneath the effort directed toward the accumulation of worldly goods lies all too frequently the illusion that this is the most substantial and desirable end to be achieved; but there is, fortunately, a minority composed of those who recognize early in their lives that the most beautiful and satisfying experiences open to humankind are not derived from the outside, but are bound up with the development of the individual's own feeling, thinking and acting. The genuine artists, investigators and thinkers have always been persons of this kind. However inconspicuously the life of these individuals runs its course, none the less the fruits of their endeavors are the most valuable contributions which one generation can make to its successors.

Within the past few days a distinguished mathematician, Professor Emmy Noether, formerly connected with the University of Göttingen and for the past two years at Bryn Mawr College, died in her fifty-third year. In the judgment of the most competent living mathematicians, Fräulein Noether was the most significant creative mathematical genius thus far produced since the higher education of women began. In the realm of algebra, in which the most gifted mathematicians have been busy for centuries, she discovered methods which have proved of enormous importance in the development of the present-day younger generation of mathematicians. Pure mathematics is, in its way, the poetry of logical ideas. One seeks the most general ideas of operation which will bring together in simple, logical and unified form the largest possible circle of formal relationships. In this effort toward logical beauty spiritual formulas are discovered necessary for the deeper penetration into the laws of nature.

Born in a Jewish family distinguished for the love of learning, Emmy Noether, who, in spite of the efforts of the great Göttingen mathematician, Hilbert, never reached the academic standing due her in her own country, none the less surrounded herself with a group of students and investigators at Göttingen, who have already become distinguished as teachers and investigators. Her unselfish, significant work over a period of many years was rewarded by the new rulers of Germany with a dismissal, which cost her the means of maintaining her simple life and the opportunity to carry on her mathematical studies. Farsighted friends of science in this country were fortunately able to make such arrangements at Bryn Mawr College and at Princeton that she found in America up to the day of her death not only colleagues who esteemed her friendship but grateful pupils whose enthusiasm made her last years the happiest and perhaps the most fruitful of her entire career.

Princeton University, May 1, 1935.
