Wonderful and extraordinary creations by physicist/artist Theo Jansen.
Kay Ryan: Repulsive Theory
Little has been made
of the soft, skirting action
of magnets reversed,
while much has been
made of attraction.
But is it not this pillowy
principle of repulsion
that produces the
doily edges of oceans
or the arabesques of thought?
And do these cutout coasts
and incurved rhetorical beaches
not baffle the onslaught
of the sea or objectionable people
and give private life
what small protection it's got?
Praise then the oiled motions
of avoidance, the pearly
convolutions of all that
slides off or takes a
wide berth; praise every
eddying vacancy of Earth,
all the dimpled depths
of pooling space, the whole
swirl set up by fending-off—
extending far beyond the personal,
I'm convinced—
immense and good
in a cosmological sense:
unpressing us against
each other, lending
the necessary never
to never-ending.
Markus Kayser - Solar Sinter
When we were discussing plans for a new project last week, Physicist John Tisch introduced me to the very nice work of Markus Kayser.....
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."
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
-------
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.
