I can explain everything

Distinguished mathematician Roger Penrose has written a thousand-page
explanation of physics that rivals Newton's Principia in its scope and
ambition

There is a disconcerting moment in Hawking, the BBC2 drama about the
wheelchair-bound Cambridge physicist, when a large, gormless young man
announces to a startled barmaid: 'I think in a number of dimensions. I
can't get back quickly for words or beer.' Later, the same nitwit is
seen spouting scientific cliches at a open-air tutorial and then ends
the programme cavorting round a railway station with Hawking (played
by Benedict Cumberbatch), using umbrellas as props to reveal the
secrets of space and time.
In this way, Sir Roger Penrose, a founder of modern cosmology, one of
the nation's intellectual heavyweights, and a collaborator with
Stephen Hawking on the science of black holes, is presented to the
public - as a pompous blabbermouth who cannot even order a pint.
The reality, it should be noted, is very different and it says a great
deal for the man - impish, intense and utterly lacking in
self-importance - that he refrains from striking me after I raise the
subject of Hawking during our meeting in the Tsar Bar in London's
Langham Hotel, where he also shows himself perfectly capable of
ordering a drink. 'Yes, I am in the programme in the sense that an
actor [Tom Ward] plays someone with my name,' says Penrose, whose
latest book, The Road to Reality (Cape £30, pp1,094), is published
this month. 'The rest makes me cringe. I never said anything like that
in a pub, I never spoke like that at a tutorial and the station scene
with Hawking never happened.'
Thus science is turned to fiction by TV producers who have no faith in
its intrinsic fascination: scenes are manufactured and scientists made
freaks or buffoons. Too bad if these are people who are interesting in
their own right, a point perfectly exemplified by Penrose, whose
mathematics inspired artist MC Escher, who has the distinction of
suing a lavatory-paper maker over the misuse of scientific ideas, who
has aroused the fury of evolutionary biologists for debunking their
ideas about human consciousness, and whose latest book rivals Newton's
Principia for its depth and ambition in its attempt to provide a
complete account of the physical universe and its laws.
It's an impressive list of achievements, a pedigree that is shared by
the rest of the Penrose family. His father was an Oxford professor of
genetics, his elder brother and only sister are academics, while
Jonathan, the youngest Penrose, was British chess champion 10 times. A
cerebral lot, though they are also highly artistic - Penrose's
grandfather was a professional portrait painter and for family fun
used to draw strange optical illusions on paper: winding staircases
that neither ascended or descended, that sort of thing.
After a chance meeting with Escher, the Dutch artist noted for his
disconcerting, illusional artwork, Penrose sent him examples of his
family's art, and these were adopted (and acknowledged) by the painter
in some of his later work. Much of this involved interlocking grids of
repeated figures - ducks and fish, for example - and Penrose later
developed these ideas to create ways of covering surfaces with flat,
geometric shapes that never repeat themselves: Penrose tiling, as it
is now known.
The mathematician would have forgotten his brainchild had his wife,
Vanessa, not noticed the packet of Kleenex Quilted Toilet Tissues she
had just bought in her local supermarket had a pattern that bore more
than a passing resemblance to her husband's tiling. In fact, it had
been appropriated by the company. Lawyers were called in. 'I should
explain the loo-roll business except I cannot as there was an
out-of-court settlement, a condition of which is that I am not allowed
to talk about it,' says Penrose rather unhelpfully, though his smile
suggests there was a happy outcome.
In fact, Penrose made his name as an outstandingly brilliant
mathematician, not from his topological work but from his forays into
the esoteric land of quantum physics, working at Cambridge with
Hawking on black holes, collapsed stars so dense even light cannot
leave their surfaces. His was a reputation of quiet distinction until,
a few years ago, he launched a furious attack on computer experts who
were claiming their machines would become clever enough to develop
minds. 'We will never make computers conscious,' he says, a point
emphasised in his books, The Emperor's New Mind, and Shadows of the
Mind. 'A computational device is incapable of developing a mind. We
got consciousness not just by being clever.'
These ideas went down badly with evolutionary biologists and
philosophers like Daniel Dennett. To such researchers, the notion that
humans are specially elevated because they suddenly came to possess
consciousness stinks of godly intervention. 'Quite fallacious',
'wrong', 'invalid' and 'deeply flawed' ran the reviews. Penrose sighs.
'Yes, I got it in the neck. But these people were not listening to
what I was saying. They were just shooting from the hip.'
His consciousness books have led directly to The Road to Reality.
'Colleagues liked my equations but not the contentious stuff about the
mind and urged me to write a straightforward book on physics. I
thought it would be a simple scissors job but it didn't work out that
way.'
In the end, Penrose, who was 73 last week, produced a great, fat,
black hole of a book that makes Bill Bryson's 600-page A Short History
of Nearly Everything look like a theatre programme. It weighs more
than 3lbs and its 1,094 pages are packed with equations and artwork -
drawn freehand by Penrose - of Riemann surfaces, singularities and
other mathematical oddities. It is a vast, formidable undertaking that
covers the entire gamut of physics, from Greek astronomy to
superstring theory.
As one reviewer remarked: 'The book took Penrose eight years to
complete, and it will take some readers just as long to understand
him.' Certainly, the book has it all: calculus, quantum mechanics,
relativity, the big bang, string theory and just about anything ever
written that has a number in it. If you want to know what makes the
universe tick, you will find it here. Not bad for a gormless
lounge-bar poser.
