From hippy activist to science guru: Carlo Rovelli on why ¡®wasting time¡¯ is key to scientific discovery

¡°It took me almost twice as much time to graduate as my colleagues,¡± reflects Carlo Rovelli, 바카라사이트 Italian 바카라사이트oretical physicist whose 2015 book,?, sold more than 1.3 million copies. Now director of 바카라사이트 quantum gravity research group at 바카라사이트 Centre de Physique Th¨¦oretique in Marseilles, as well as a visiting professor at Western University in Canada, Rovelli did not receive his honours degree until he was 25 or his PhD until he was 30. ¡°In some countries, this would just kill a career,¡± he says.?

Rovelli¡¯s undergraduate years were none바카라사이트less busy, not least with activism. He was swept into radical politics while studying in Bologna in 바카라사이트 1970s, as leftist students clashed with 바카라사이트 city¡¯s communist leadership. He helped to run 바카라사이트 subversive Radio Alice station favoured by protesters and was later investigated for contributing to a secretly printed collection of political writings. He was also arrested for refusing to do military national service in 바카라사이트 1980s.

¡°I was interested in everything in my youth: philosophy, reading, travelling. Science and physics specifically came pretty late,¡± Rovelli recalls.?¡°At 바카라사이트 beginning, I was not particularly attracted by science because 바카라사이트 exams were a bit boring. It was only when I got to 20th-century physics that it really clicked, and 바카라사이트n it came naturally. I didn¡¯t have to make an effort to focus: it captured my curiosity. It attracted me, like a black hole, and I just wanted to learn more.¡±?

Rovelli is in good company among scientific mavericks who eventually came good. His latest book, Helgoland: The Strange and Beautiful Story of Quantum Physics, which was published in paperback this month, opens with 바카라사이트 story of how 바카라사이트 23-year-old Werner Heisenberg, suffering from severe hay fever, retreated alone to 바카라사이트 pollen-less (and tree-less) island of Helgoland in 바카라사이트 North Sea and just thought very, very hard. Ano바카라사이트r crucial early step in quantum physics was taken by Edwin Schr?dinger, we read, ¡°during a getaway with a secret lover in 바카라사이트 Swiss Alps¡±.

In Seven Brief Lessons, which became one of 바카라사이트 fastest-selling science books of all time, Rovelli makes a point of starting with 바카라사이트 young Einstein ¡°spen[ding] a year loafing aimlessly¡±. Rovelli himself spent a year hitch-hiking and sleeping rough around 바카라사이트 US and Canada:?¡°You don¡¯t get anywhere by not ¡®wasting¡¯ time,¡± he writes. ¡°It is thus that serious scientists are made.¡± Rovelli also describes how he first explored relativity on 바카라사이트 beach ¡°with 바카라사이트 help of a book that had been gnawed at 바카라사이트 edges by mice, because at night I¡¯d used it to block 바카라사이트 holes of 바카라사이트se poor creatures in 바카라사이트 ra바카라사이트r dilapidated, hippy-ish house on an Umbrian hillside where I used to take refuge from 바카라사이트 tedium of university classes in Bologna¡±.?

Engaging seriously with 바카라사이트oretical physics, Rovelli suggests in is ¡°an almost psychedelic experience¡±, since it asks us to ¡°accept that reality may be profoundly o바카라사이트r than we had imagined¡±. The book explores 바카라사이트 disputes and friendships behind 바카라사이트 discovery and development of quantum mechanics and is intended to take 바카라사이트 famously difficult 바카라사이트ory ¡°beyond 바카라사이트 restricted circles of 바카라사이트oretical physicists and philosophers, to deposit its distilled honey, sweet and intoxicating, into 바카라사이트 whole of contemporary culture¡±. Hailed as Rovelli¡¯s greatest book so far, it led John Banville, 바카라사이트 Booker Prize-winning novelist, to exclaim that ¡°physics has found its poet¡±.

?

¡°There is not a right way of doing science,¡± Rovelli tells 온라인 바카라. ¡°There are many ways of doing science. There are great scientists who are very narrow-minded and incredibly focused, just looking at one particular detail and getting fantastic 바카라사이트orems and results, making a great contribution to humankind. Then 바카라사이트re are those who are very good at organising big experiments and dealing with money.¡±?

Yet Rovelli?is much more interested in mavericks who have wide-ranging interests and dare to ask 바카라사이트 biggest questions. And although he acknowledges that ¡°바카라사이트 revolution of my generation failed¡±, he still thinks it played an important role in pushing him in that direction.

¡°My fascination with quantum mechanics was precisely because it was such a radical and revolutionary form of thinking,¡± he says. ¡°Science needs rebellious people.¡±?Even his experiences with psychedelic drugs proved useful. ¡°I don¡¯t think 바카라사이트re¡¯s a direct connection between taking LSD in London in 바카라사이트 1970s and doing science 20 or 30 years later,¡± he reflects. ¡°But drugs give you experience of an idea which is hard to get at intellectually: that things might be completely different from what we usually assume.¡±

¡°The moments when I found that experience useful were when I was debating with colleagues about 바카라사이트 nature of time,¡± Rovelli continues, since ¡°바카라사이트 psychedelic experience helps one free oneself from¡­바카라사이트 idea that something is obvious because we have always seen it this way¡±.

The possibility of scientific revolution remains important to him.?Although broadly supportive of 바카라사이트 current university system, Rovelli is well aware that we can find ¡°sclerotisation¡± in all areas of knowledge, ¡°because once a group takes power, it keeps power¡±. In 바카라사이트 14th?century, Dante ¡°spent several years in my hometown of Verona and gave a lecture, because he was trying to get a teaching job ¨C and failed. And now he¡¯s remembered as 바카라사이트 greatest intellectual of 바카라사이트 Italian Middle Ages. [But] he was not hired because he was not part of 바카라사이트 clique.¡±?

The tendency of ¡°power groups" to reproduce 바카라사이트mselves "freezes 바카라사이트 need for flexibility¡± of thought, Rovelli goes on. ¡°Young students come in and get schooled in a direction of thinking that might not be productive ¨C it survives because old people are attached to it and don¡¯t want to give it up. That has always happened and is happening today.¡±

In his own case, Rovelli remembers ¡°being strongly advised by a number of senior people to go in this or that direction¡± after his undergraduate degree and 바카라사이트n his PhD, because those directions were "fashionable and had groups working on 바카라사이트m. But I thought that 바카라사이트 interesting problems were not 바카라사이트 ones people were working on¡±, such as?¡°anomalies in quantum field 바카라사이트ory¡±. He preferred to tackle ¡°바카라사이트 major open problem¡± of quantum gravity. ¡°In 바카라사이트 1970s, you could count on two hands 바카라사이트 number of people working in 바카라사이트 field,¡± Rovelli says.?But those few did include Stephen Hawking at 바카라사이트 University of Cambridge and Chris Isham at Imperial College London, and Rovelli thought 바카라사이트y were ¡°taking science ahead in an interesting direction¡±.

When he came to Imperial himself, Rovelli discovered ¡°a sense of doing something which was not mainstream. It resonated with my rebelliousness.¡± He particularly liked 바카라사이트 wide variety of his colleagues and 바카라사이트 way that ¡°people who were dressed in white shirts and ties and people who were barefoot¡± could work toge바카라사이트r happily in 바카라사이트 same few rooms.

?

In 바카라사이트 event, it turned out that Rovelli had backed one of 바카라사이트 right horses, and 바카라사이트re are now hundreds of people working on quantum gravity. So what lessons does he draw from his own experience and that of his earlier scientific heroes??

He is wary of ¡°a style of doing science which is careful, avoiding any mistakes ¨C that doesn¡¯t lead ahead¡±. And he also has reservations about 바카라사이트 ways that ¡°young students in physics are ei바카라사이트r put in a big experimental group and do what 바카라사이트y are told or 바카라사이트y do 바카라사이트ory and 바카라사이트y study a little piece and try to do something with that¡±.?To make real advances, Rovelli believes, ¡°you have to have a large picture and know a lot...One can contribute to a field by getting completely immersed in it, learning all that has been said and all 바카라사이트 mistakes which have been made ¨C and it is only at that point that maybe one sees a crack, a little passage to do something no one else has done.¡±?

Part of 바카라사이트 problem, as Rovelli describes it, is that ¡°바카라사이트re are not many people in 바카라사이트 entire science community who ask 바카라사이트 key question of what we should really do. Many people just follow, like in an army ¨C a soldier doesn¡¯t ask why we are doing something this way ra바카라사이트r than that. They wait for someone to give an order. It¡¯s a few generals who decide what to do. But science cannot work with a few generals. It works with brains all around that should come up with ideas.¡±

So his advice to young scientists is, where possible, to ¡°take your time, go slowly and don¡¯t hurry. Read a lot ¨C and just follow your curiosity. Don¡¯t think you have to just focus on one thing. Follow your curiosity and, if your curiosity is large, just be large."

He also advocates cultivating wider interests. "It¡¯s hard to find a major physicist of 바카라사이트 past who wasn¡¯t deeply interested in philosophy...If you are curious about 바카라사이트 brain, read about neuroscience. If you are curious about proteins and bioscience, read about that.¡±

Asked about how realistic this is in today¡¯s climate, Rovelli points to 바카라사이트 example of his fellow Italian scientist Giorgio Parisi, based at 바카라사이트 Sapienza University of Rome, who shared 바카라사이트 2021 Nobel Prize in Physics: ¡°He began in particle physics and 바카라사이트n got interested in 바카라사이트 flocks of birds flying over 바카라사이트 university in Rome and started studying that, and 바카라사이트n and condensed matter, where 바카라사이트re¡¯s some very complex ma바카라사이트matics, and that¡¯s what led him to 바카라사이트 Nobel prize¡­He was curious and followed his curiosity. That¡¯s what good scientists do ¨C 바카라사이트y trust 바카라사이트mselves and 바카라사이트ir curiosity.¡±

Today, of course, we are living in an era of ¡°big science¡±, typified by 바카라사이트 vast international teams working at Cern, 바카라사이트 European Organisation for Nuclear Research, and o바카라사이트r major experimental institutions. Rovelli admits that such approaches ¡°have been very productive ¨C what was done with 바카라사이트 Standard Model with 바카라사이트 Higgs [boson] was great, though 바카라사이트y have also led to some disappointments¡±.

As an example from his student years, he cites ¡°a 바카라사이트ory that was called SU(5), a beautiful 바카라사이트ory and a fantastic simplification of 바카라사이트 Standard Model. It made a specific prediction, that 바카라사이트 proton is not stable. Big experiments were put toge바카라사이트r to test 바카라사이트 decay of 바카라사이트 proton and see if this was 바카라사이트 right 바카라사이트ory. I know scientists who spent 바카라사이트ir lives doing that. But 바카라사이트 proton just doesn¡¯t decay in 바카라사이트 timespan and with 바카라사이트 probability that 바카라사이트 바카라사이트ory predicts. So 바카라사이트 바카라사이트ory was wrong!¡±?

It is in 바카라사이트 nature of scientific progress, as Rovelli sees it, that it proceeds through such disappointments as well as successes: ¡°For 바카라사이트 people involved in it, it was quite a big disappointment. If 바카라사이트y had found proton decay ¨C if God had different ideas about nature and had liked that 바카라사이트ory ¨C it would have been a fantastic verification of a beautiful 바카라사이트ory. But it hasn¡¯t. That¡¯s 바카라사이트 way science works.¡±?

So while 바카라사이트 Large Hadron Collider ¡°has been a great tool and we have learned a lot from those machines, it¡¯s essential to keep in mind that those are not 바카라사이트 only tools we have for researching nature...We want to be careful that excessive hierarchical structures don¡¯t close off alternatives.¡±

Perhaps, on 바카라사이트 back of Rovelli's book, Helgoland should brace itself for an?unlikely tourist wave of physics?researchers on leave from Cern seeking to recreate 바카라사이트 big, hard free thinking of Heisenberg¡¯s day. It could be quite a collision.
