Secret of Scientific Creativity revealed by Andre Geim, ‘godfather of graphene’

At a Hay Festival event sponsored by the Royal Society, Director of External Affairs Roger Highfield interviewed Andre Geim, the Nobel prize winner best known for his work on graphene, the subject of an exhibition that will open next year at the Museum of Science & Industry, Manchester. 

He created graphene, the first two dimensional object on the planet. He levitated frogs. And his pet hamster too. He created tape that mimics the adhesive properties of Gecko feet. But what makes the Nobel Prize winner Andre Geim one of the most creative figures in physics?

A revealing glimpse of how his mind makes adventurous leaps in supposedly well-trodden areas of research emerged when I interviewed the Regius Professor and Royal Society Research Professor at Manchester University, who is best known for his research on the wonder material graphene, along with his deadpan wit and candour.

Born in Sochi and raised in Soviet-era Russia, Geim does not pinpoint his success to being inspired by a particular teacher or childhood experience but being gifted in mathematics and physics and stimulated by a peripatetic existence, aided by the end of the Cold War and a basic hunger for new experiences.

He is serious about play, enjoying stressful hikes across Borneo, and an eventful trip to the Grand Canyon, where he endured both pneumonia and a rattlesnake bite. Equally, he is playful about the serious business of work. ‘I measure life not in years but in experiences.’

Our Hay event was entitled ‘Random Walk to Graphene,’ in honour of his Nobel lecture on a ‘random walk to Stockholm’, a nod to the mathematical term used to describe a path that consists of a succession of random steps. Because his career trajectory has been a little random, he feels that he has learned something new at every step.

This is a far cry from the traditional blinkered way of doing science, which he encountered first-hand when he conducted the equivalent of a doctorate at the Institute of Solid State Physics at the Russian Academy of Sciences in Chernogolovka.

A slide from his Nobel lecture shows his 1987 thesis citation was entitled: “Investigation of mechanisms of transport relaxation in metals by a helicon resonance method” (He told the Hay audience: ‘I really have forgotten what is was all about.’)

Geim said that many of the six or seven million people worldwide who do professional research are trapped in a style of science that he likens to ‘a railway from your scientific cradle to scientific coffin’, one which is ‘absolutely straight’ and where diversions are not allowed.

In the eighties, ‘I did two or three papers which were cited once or twice by my supervisor, no one else,’ he said. ‘That was the experience of my PhD.’ Bottom line, never torture students with what he calls ‘zombie projects.’

Wind forward to Radboud University Nijmegen High Field Magnet Laboratory in the Netherlands where he had ended up, attracted by the greater opportunities and freedom in the West: the Royal Society had sponsored a visit to the University of Nottingham during which he achieved more in his first six months than in the previous ‘six years of boredom.’

One Friday in Nijmegen, two decades of curiosity about the phenomenon of diamagnetism got the better of him. He poured a bottle of water into one of the lab’s powerful electromagnets, some 50 times stronger than a fridge magnet. It was in the evening, when the electricity was cheaper. Lo and behold droplets of water started floating in the powerful magnetic field. ‘It is a ridiculous experiment,’ he conceded. ‘But nobody had come with the same stupid idea.’

His colleagues suggested he now try beer. Instead, his wife and fellow physicist Irina Grigorieva, who accompanied him and their daughter to Hay, ’came up with a brilliant idea.’ He should try a frog too, just to underline to scientific sceptics as much as the layperson how everything is diamagnetic.

The Geim family pet hamster Tisha was quickly levitated. Not only did he live to squeak the tale for another three years, he even co-authored a paper with Geim in the journal Physical B to, as Geim puts it, ‘acknowledge his personal contribution.’ Geim wanted to ensure his work had real impact rather than swell the ranks of uncited papers.

The rest is history and he won the ‘Ig Nobel prize’ for innovations that make people ‘laugh, then think.’ But ‘behind every joke there is something very serious.’ He shared the Ig Nobel Prize with Sir Michael Berry of the University of Bristol, who had worked with Geim on the theory of levitation. Even today, scientists come up to Geim at conferences and say. ‘I have no idea about graphene’ and then talk in delight about his levitating frog.

Geim has since enshrined the idea of the Friday Night Experiment in his way of working. His playfulness and commitment to scientific adventure (‘search, not re-search’) was what attracted Kostya Novoselov to Geim’s laboratory in Holland.

And it was what would take them both on a random walk to the Nobel prize, after a wrong first step by Geim’s first PhD student when he moved to the University of Manchester. Da Jiang had arrived from China with poor English and in 2002 Geim gave him a simple project: take a piece of graphite, the stuff of pencils, albeit a chunk worth around £300, and isolate the thinnest sliver he could.

Geim wanted to study a two-dimensional sheet of carbon atoms that had long been posited by theorists, and was predicted to have fascinating electronic properties, but had never been seen. This Friday Night Experiment  was a step in the wrong direction: Da Jiang used a specialised machine to grind the piece of graphene down to a little piece. ‘It was not thin enough’ and Geim asked him to try again. Da Jiang requested another piece of graphite and, given he had reduced the last to dust, ‘You can imagine how excited I was’.

Then Geim’s Ukrainian postdoc Oleg Shklyarevskii took an interest and had an idea: physicists used Scotch tape to clean graphite, which is commonly studied in laboratories. ‘What those guys did not realise,’ explained Geim, ‘was that throwing away the Scotch tape they were throwing away the Nobel Prize as well.’

After rummaging in the bin, pieces of tape emerged coated with ultrathin graphite: not atomic thickness but transparent, which raised the hopes of Geim that graphene could be made. ‘I knew that if it is transparent it must be very, very thin. From the very first moment I knew that we could get with this technique something that has never been studied before.’

Here Novoselov re-enters the story and lo and behold after a year to 18 months, they isolated a hexagonal lattice of carbon atoms. The flat, parallel sheets of carbon atoms in the graphite of pencil lead could indeed be peeled apart to yield a single atomic layer.  (Geim hates calling this the ‘Scotch tape technique,’ which is ‘plebeian.’)

Geim’s random, playful leaps across physics are not as effortless as they sound: it takes careful background research to make sense of what many others have done before, do something different, and to describe a novel leap in familiar terms that peers can understand. This exercise in due diligence is not helped by the vast amounts of chaff in the scientific literature: he points out that of the 100,000 or so research papers each year (excluding those from China), half are never cited.

Their first paper about the isolation of graphene was rejected when it was sent to Nature. Although one referee remarked ‘this paper does not represent a scientific advance,’ Geim is sanguine about the conservatism of science. Eventually it was accepted and published in the journal Science in 2004.

It was astounding that heat energy (‘Brownian motion’) did not shake graphene’s gossamer atomic lattice apart, a hint of its extraordinary properties – miraculous strength, lightness, flexibility – and conductivity too. This material was 100 times stronger than steel and 100 times more conductive than copper, promising a wealth of applications, from supercapacitors and composites to lighting and superfast electronics.

By 2010, the first paper by Novoselov and Geim was cited more than 3,000 times. That same year, they shared the Nobel Prize, though Geim says that, in reality, ‘six or seven people’ were behind the breakthrough.

And how did he feel when the call from the Nobel committee came? ‘People were expecting me to win the prize for two or three years before,’ he said. ‘In a sense I was mentally prepared that there would be a call.’ But he messed up the actual timing and did not realise that it would be that particular Monday when the prize was announced. Still, when a female voice with a Swedish accent materialised on his phone to say she had something very important to tell him,’ he immediately replied: “Are you going to tell me that I won the Nobel prize?”

‘Nothing changed that day. I went to work. I had a few drinks. Otherwise, nothing special. ’There were plenty of calls from journalists but ‘it was not very interesting. Journalism is not my favourite profession. Sorry, Roger…they write quicker than they think.’

Today Geim maintains a small, close-knit team of two postdocs and two or three students. He believes in the power of ‘self-organisation’, quickly losing interest in students who do not pass muster. He wants to do science, not admin: ‘I am in the lab several times a day.’ He has resisted the temptation to build an empire.

Even though his work has spawned a £61 million National Graphene Institute in Manchester, ‘a good facility’ he is ambivalent about the relatively small scale of the effort compared with rival nations, the sluggishness of the UK response to the race to commercialise graphene, and how the money was spent on the building rather than research (architects, along with politicians, journalists and students attract his ire). ‘It is money put into the British building industry rather than science.’

He has met Chancellor George Osborne a couple of times but quickly lost interest. ‘I am not an industrialist or property developer…my strength is probably being a little bit unconventional…I am not interested in political games.’

Graphene is now ‘more or less done’, he said. His latest research is backed mostly by European Union funding, which he says is more focused on blue sky than immediate returns. Geim has now moved on to creating novel designer materials by assembling the emerging family of two dimensional ‘brothers and sisters of graphene’, including hexagonal boron nitride, fluorographene and so on, in a Lego-like fashion. His hope is that these metamaterials will have extraordinary new properties for instance for quantum computers and much more. The world is entering the era of what he calls ‘Graphene 3.0’.

A Nobel Tradition

Content Developer Rupert Cole explores the most famous science prize of all, and some of its remarkable winners. 

Today, science’s most prestigious and famous accolades will be awarded in Stockholm: the Nobel Prize.

Before we raise a toast to this years’ winners in physics, Peter Higgs and Belgian François Englert, let’s take a look back at the man behind the Prize, and some of its winners.

Alfred Nobel

A Swedish explosives pioneer who made his millions from inventing dynamite, Alfred Nobel left in his will a bequest to establish an annual prize for those who have “conferred the greatest benefit to mankind”, across five domains: physics, chemistry, physiology or medicine, literature and peace. To this end, he allocated the majority of his enormous wealth.

When Nobel’s will was read after his death in 1896, the prize caused an international controversy. Unsurprisingly, Nobel’s family were not best pleased, and vigorously opposed its establishment. It took five years before it was finally set up and the first lot awarded – the 1901 physics accolade going to Wilhelm Rontgen for his 1895 discovery of x-rays.

Paul Dirac’s maternal mortification

When the phone rang on 9 November 1933, the exceptionally gifted yet eccentric Paul Dirac was a little taken back to hear a voice from Stockholm tell him he had won the Nobel Prize.

The looming press attention, which had always surrounded the Nobels, made the reclusive Dirac consider rejecting the award, until Ernest Rutherford – JJ Thomson’s former student and successor as Cavendish professor – advised him that a “refusal will get you more publicity”.

Under different circumstances Rutherford had been similarly “startled” when he found out he was to be given a Nobel – a physicist through and through, he was awarded the 1908 Prize in Chemistry, joking his sudden “metamorphosis into a chemist” was very unexpected.

Dirac shared the 1933 physics prize with Erwin Schrödinger – famed for his eponymous equation and dead-and-alive cat – for their contributions to quantum mechanics. Each was allowed one guest at the award ceremony held at the Swedish Royal Academy of Science. Schrödinger brought his wife, Dirac brought his mother.

Florence Dirac did what all good mothers do: embarrass her son in every way imaginable. The first incident came at a station café in Malmo, where in this unlikely setting an impromptu press conference took place.

Dirac, who had been described by the British papers as “shy as a gazelle and modest as a Victorian maid,” was asked “did the Nobel Prize come as a surprise?” Before he could answer, Dirac’s mother butted in: “Oh no, not particularly, I have been waiting for him to receive the prize as hard as he has been working.”

The next embarrassment came when Mrs Dirac failed to wake up when the train reached Stockholm. She was ejected by a guard, who had thrown her garments and belongings out of the carriage window. The Diracs arrived late, and meekly hid from the attention of the welcoming party – who had been wondering where they were.

The third and final maternal faux pas came at Stockholm’s Grand Hotel. The pair had been booked into the finest room – the bridal suite. Mrs Dirac, displeased, demanded a room of her own, which Dirac paid for out of his own pocket. It doesn’t matter if you’ve co-founded quantum mechanics, predicted antimatter and won the Nobel Prize; mothers will be mothers.

Peter’s Pride

Like other humble laureates before him, Peter Higgs wished to duck out of the press furore surrounding the Nobel. At the time of the announcement on the 8th October there was a nail-biting delay. The cause? The Nobel committee could not get hold of Higgs, who had turned his phone off and planned to escape to the Scottish Highlands.

As Peter Higgs revealed to me at the opening of the Collider exhibition at the Science Museum, if it was not for a dodgy Volkswagen beetle or public transport, Peter would have made it to the Highlands on Nobel day. Instead, he just laid low in Edinburgh.

At the Collider launch last month, we celebrated with Higgs in the appropriate way: over a personalised bottle of London Pride ale – the same beverage he chose in favour of champagne on the flight home from CERN’s public announcement of the Higgs boson discovery. So, when Englert and Higgs receive the honour today, let’s all raise two glasses: an English Ale and a Belgian Blonde!

For more on many of the Nobel prize-winning discoveries in physics history, including those of Dirac, Englert and Higgs, visit the Collider exhibition at the Science Museum.

The last particle?

Could the Higgs be the end of particle physics? We’re still a long way from answering one of the biggest questions of all, says Dr Harry Cliff, Head of Content on our Collider exhibition.

The 2013 Nobel Prize in Physics has been awarded to François Englert and Peter Higgs for their work that explains why subatomic particles have mass. They predicted the existence of the Higgs boson, a fundamental particle, which was confirmed last year by experiments conducted at CERN’s Large Hadron Collider.

But today’s celebrations mask a growing anxiety among physicists. The discovery of the Higgs boson is an undoubted triumph, but many note that it hasn’t brought us any closer to answering some of the most troubling problems in fundamental science.

A senior physicist went so far as to tell me that he was “totally unexcited by the discovery of the Higgs boson”. Though not the typical reaction, this discovery threatens to close a chapter of 20th century physics without a hint of how to start writing the next page.

Until July last year, when physicists at the Large Hadron Collider (LHC) announced its discovery, the Higgs boson remained the last missing piece of the Standard Model of particle physics, a theory that describes all the particles that make up the world we live in with stunning accuracy. The Standard Model has passed every experimental test thrown at it with flying colours, and yet has some rather embarrassing holes.

According to astronomical measurements, the matter described by the Standard Model that makes up the stars, planets and ultimately us, only accounts for a tiny fraction of the universe. We appear to be a thin layer of froth, floating on top of an invisible ocean of dark matter and dark energy, about which we know almost nothing.

Worse still, according to the Standard Model, we shouldn’t exist at all. The theory predicts that, after the Big Bang, equal quantities of matter and antimatter should have obliterated each other, leaving an empty universe.

Both of these are good scientific reasons to doubt that the Standard Model is the end of the story when it comes to the laws of physics. But there is another, aesthetic principle that has led many physicists to doubt its completeness – the principle of “naturalness”.

The Standard Model is regarded as a highly “unnatural” theory. Aside from having a large number of different particles and forces, many of which seem surplus to requirement, it is also very precariously balanced. If you change any of the 20+ numbers that have to be put into the theory even a little, you rapidly find yourself living in a universe without atoms. This spooky fine-tuning worries many physicists, leaving the universe looking as though it has been set up in just the right way for life to exist.

The Higgs’s boson provides us with one of the worst cases of unnatural fine-tuning. A surprising discovery of the 20th century was the realisation that empty space is far from empty. The vacuum is, in fact, a broiling soup of invisible “virtual” particles, constantly popping in and out of existence.

The conventional wisdom states that as the Higgs boson passes through the vacuum it interacts with this soup of virtual particles and this interaction drives its mass to an absolutely enormous value – potentially up to a hundred million billion times larger than the one measured at the LHC.

Theorists have attempted to tame the unruly Higgs mass by proposing extensions of the Standard Model. The most popular of which is “supersymmetry”, which introduces a heavier super-particle or “sparticle” for every particle in the Standard Model. These sparticles cancel out the effect of the virtual particles in the vacuum, reducing the Higgs mass to a reasonable value and eliminating the need for any unpleasant fine-tuning.

Supersymmetry has other features that have made it popular with physicists. Perhaps its best selling point is that one of these sparticles provides a neat explanation for the mysterious dark matter that makes up about a quarter of the universe.

Although discovering the Higgs boson may have been put forward as the main reason for building the 27km Large Hadron Collider (LHC), what most physicists have really been waiting for is a sign of something new. As Higgs himself said shortly after the discovery last year, “[The Higgs boson] is not the most interesting thing that the LHC is looking for”.

So far however, the LHC has turned up nothing.

If supersymmetry is really responsible for keeping the Higgs boson’s mass low, then sparticles should show up at energies not much higher than where the LHC found the Higgs. The fact that nothing has been found has already ruled out many popular forms of supersymmetry.

This has led some theorists to abandon naturalness altogether. One relatively new idea known as “split-supersymmetry” accepts fine-tuning in the Higgs mass, but keeps the other nice features of supersymmetry, like a dark matter particle.

This may sound like a technical difference, but the implications for the nature of our universe are profound. The argument is that we live in a fine-tuned universe because it happens to be one among an effectively infinite number of different universes, each with different laws of physics. The constants of nature are what they are because if they were different atoms could not form, and hence we wouldn’t be around to wonder about them.

This anthropic argument is in part motivated by developments in string theory, a potential “theory of everything”, for which there are a vast number (roughly 10500) different possible universes with different laws of physics. (This huge number of universes is often used as a criticism of string theory, sometimes derided as a “theory of everything else” as no one has so far found a solution that corresponds to the universe we live in.) However, if split-supersymmetry is right, the lack of new physics at the LHC could be indirect evidence for the existence of the very multiverse anticipated by string theory.

All of this could be rather bad news for the LHC. If the battle for naturalness is lost, then there is no reason why new particles must appear in the next few years. Some physicists are campaigning for an even larger collider, four times longer and seven times more powerful than the LHC.

This monster collider could be used to settle the question once and for all, but it’s hard to imagine that such a machine will get the go ahead, especially if the LHC fails to find anything beyond the Higgs.

We are at a critical juncture in particle physics. Perhaps after it restarts the LHC in 2015, it will uncover new particles, naturalness will survive and particle physicists will stay in business. There are reasons to be optimistic. After all, we know that there must be something new that explains dark matter, and there remains a good chance that the LHC will find it.

But perhaps, just perhaps, the LHC will find nothing. The Higgs boson could be particle physics’ swansong, the last particle of the accelerator age. Though a worrying possibility for experimentalists, such a result could lead to a profound shift in our understanding of the universe, and our place in it.

Celebrate the Nobel Prize at the Science Museum

Roger Highfield, Director of External Affairs at the Science Museum, celebrates the 2013 Nobel Prize for Physics ahead of the opening of our Collider exhibition next month.      

Congratulations to Briton Peter Higgs and Belgian François Englert, winners of the 2013 Nobel Prize for Physics “for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN’s Large Hadron Collider.”

A few minutes ago, after an unusual delay, the Royal Swedish Academy of Sciences announced the winners of the physics prize in Stockholm, ending this chapter of the quest for new elementary particles, the greatest intellectual adventure to date.

Ian Blatchford, Director of the Science Museum, comments: “That it has taken decades to validate the existence of the Higgs Boson illustrates the remarkable vision of the theoretical work that Higgs, Francois Englert and others did with pen and paper half a century ago, one that launched an effort by  thousands of scientists and inspired a staggering feat of engineering in the guise of the Large Hadron Collider.

What is the Higgs? Here’s all you need to know, in just 90 seconds, from Harry Cliff, a Cambridge University physicist working on the LHCb experiment and the first Science Museum Fellow of Modern Science

Although the identity of the winners has been a closely-guarded secret, many have speculated that those who played a central role in discovery of the long-sought Higgs, notably the emeritus Edinburgh professor himself, were leading contenders for a place in history.

The Science Museum has been so confident that the Large Hadron Collider would change our view of nature that we have invested more than £1 million, and worked closely with the European Organization for Nuclear Research, CERN, to celebrate this epic undertaking with its new exhibition, Collider: step inside the world’s greatest experiment, which opens to the public on 13 November. 

Here Higgs explains how the Large Hadron Collider works during a visit to what is now Cotham School, Bristol, where he was once a pupil.

In July 2012, two separate research teams at CERN’s £5 billion Large Hadron Collider reported evidence of a new particle thought to be the Higgs boson, technically a ripple in an invisible energy field that gives most particles their mass.

This discovery represented the final piece of the Standard Model, a framework of theory developed in the late 20th century that describes the interactions of all known subatomic particles and forces, with the exception of gravity.

Nima Arkani-Hamed, a leading theoretical physicist at the Institute for Advanced Study in Princeton who will attend the launch of Collider, bet a year’s salary the Higgs will be found at the LHC.

Another speaker at the Collider launch, the world’s most famous scientist, Prof Stephen Hawking, lost a $100 bet he made against the discovery (though he is adamant that Higgs deserves the Nobel Prize).

Higgs, who refuses to gamble, told me just before the LHC powered up that he would have been puzzled and surprised if the LHC had failed in its particle quest. “If I’m wrong, I’ll be rather sad. If it is not found, I no longer understand what I think I understand.”

When Higgs was in the CERN auditorium last year to hear scientists tell the world about the discovery, he was caught reaching for a handkerchief and dabbing his eyes.  On the flight home, he celebrated this extraordinary achievement with a can of London Pride beer.

The Science Museum hoped to have the can, now deemed a piece of history Alas, Higgs had dumped it in the rubbish before we could collect it. However, the museum does possess the champagne bottle that Higgs emptied with his friends the night before the big announcement.

The modest 84-year-old  is now synonymous with the quest: the proposed particle was named the Higgs boson in 1972.

But there have been demands that the particle be renamed to acknowledge the work of others. Deciding who should share this Nobel has been further complicated because a maximum of three people only can be honoured (prompting many to question the criteria used by the Nobel committee).

The LHC, the world’s most powerful particle accelerator, is the cumulative endeavour of around ten thousand men and women from across the globe. In recognition of this the Collider exhibition will tell the behind-the-scenes story of the Higgs discovery from the viewpoint of a young PhD student given the awesome task of announcing the discovery to her colleagues (though fictional, the character is based on Mingming Yang of MIT who is attending the launch).

However, although one suggestion is to allow the two research teams who discovered the Higgs boson to share the accolade, the Nobel committee traditionally awards science prizes to individuals and not organizations (unlike the Nobel Peace Prize).

Instead, the Nobel committee honoured the theoreticians who first anticipated the existence of the Higgs.

Six scientists published the relevant papers in 1964 though, as Belgium’s Robert Brout died in 2011, there were five contenders (the Nobel Prize cannot be given posthumously).

In August 1964, François Englert from the Free University of Brussels with Brout, published their theory of particle masses. A month later, while working at Edinburgh University, Higgs published a separate paper on the topic, followed by another in October that was – crucially – the first to explicitly state the Standard Model required the existence of a new particle. In November 1964, American physicists Dick Hagen and Gerry Guralnik and British physicist Tom Kibble added to the discussion by publishing their own research on the topic.

Last week, Prof Brian Cox of Manchester University, who works at CERN, said it would be ‘odd and perverse’ not to give the Nobel to Peter Higgs, and also singled out Lyn ‘the atom’ Evans, the Welshman in charge of building the collider, as a candidate.

And the two likeliest winners were named as Peter Higgs – after whom the particle was named – and François Englert, according to a citation analysis by Thomson Reuters.

Today’s announcement marks the formal recognition of a profound advance in human understanding, the discovery of one of the keystones of what we now understand as the fundamental building blocks of nature.
