Scientific pioneering work

The Swedish Academy of Sciences in Stockholm reached Giorgio Parisi on the phone on Tuesday during the award ceremony. He said he hadn’t expected the Nobel Prize. But he put the telephone receiver close by because he was aware of the possibility that he could be chosen.

His former sister-in-law, who lives in Berlin, told Tagesspiegel that Parisi is a very sociable person, always trying to explain his complex research field to his fellow men, even if not always with success . She describes him as a very committed person who positioned himself at his Uni La Sapienza in Rome against the lack of research funding and also warned that the natural sciences should play a greater role in Italian schools.

Parisi also saw the Covid pandemic primarily as a social challenge in which science had to create more trust. Right from the start of the pandemic, he devoted himself to explaining the numbers. But he was not satisfied with the communication of science.

Emphasize the role of science

“The vaccination opponents show us that we have not succeeded in explaining to everyone how scientific methods work,” he says somewhat resignedly in an interview with “La repubblica”.

To emphasize the role of science in the next sentence. “There is no researcher in possession of the truth or research that definitively proves anything. There is a consensus that develops gradually, along with new evidence and with a self-regulating mechanism that corrects errors. “This message was not always carried through in the pandemic.

Syukuro Manabe. Giorgio Parisi advocates the popularization of science in Italy a. “Science is no longer seen as a way to improve the future. It is losing value, ”he said in the interview.

People would live close together with extremely highly developed technologies, the scientific principles of which, however, would often not be understood. “It almost seems as if things were made by witchcraft. We should teach the basics from kindergarten. “

The team player loves Greek dances

Of the 73 – year-old physicist, who was president of the Accademia dei Lincei, is a team player, not an out-of-the-way person, according to his Berlin relatives. Even if his work on the theory of disordered materials and random processes, for which he has now been awarded, should only be understood by very few of his fellow human beings, he never isolates himself. And he loves Greek dances.

Parisi is a city dweller, the native Roman lives in the city center of the Italian capital. He returned here again and again despite several stays abroad.

Giorgio Parisi was honored for his theoretical work in connection with climate modeling. Regarding the need for climate protection, he said that the rise in temperature could accelerate further: “This requires that we act immediately for future generations.” The situation is very urgent, strong decisions are now needed.

Part of the Nobel Prize goes to Parisi for discovering how the “interplay of Disorder and fluctuations determine physical systems from the atomic to the planetary level “. The academy spoke of the “revolutionary” findings of the professor at Sapienza University in Rome.

A complex system of crucial importance for mankind is the earth’s climate. “This year’s award winners have all helped us to gain deeper insights into the properties and development of complex physical systems,” said Thors Hans Hansson, chairman of the Nobel Committee for Physics.

A first realistic climate model

A central figure in the history of climate modeling became Also awarded the Nobel Prize on Tuesday: Syukuro Manabe. In the 1958 he brought the first climate models with him – a pioneering achievement.

Of the 90 – year old Manabe was born in Japan, received his doctorate 1958 at the university Tokyo and then went to the USA. Most recently, he did research at the elite Princeton University. Already in the 1958 the climatologist had proven that the rise in temperatures on earth is related to the level of CO2 in the atmosphere.

Syukuro Manabe had with Richard Wetherald in the 60 programmed the first realistic climate model in Princeton. In doing so, he not only took into account the thermal radiation, but was also able to map the convection, the ascending and descending of warm or cold air.

The scientist, who is now also a US citizen, worked in the USA is, first with various weather authorities before moving to Princeton.

Manabe repeatedly advised various research centers in his country of birth. 1997 to 2001 he worked on the Frontier Research System for Global Change in Japan, but then returned to the USA.

Around 250 Manabe has published specialist articles and books – and has received dozens of prestigious awards. There is now even a prize in his name: The “Syukuro Manabe Climate Research Award” presented by the American Meteorological Association honors researchers who make outstanding contributions to the understanding of the earth’s climate system.

Manabe is a member of the United States National Academy of Sciences and a foreign member of the Academia Europaea and the Royal Society of Canada Models have captured these changes, then we can be very sure about the forward-looking projections, “said Manabe in an interview.

“Do everything to minimize climate change”

It is very difficult to say at what temperature the change becomes dangerous . “What we do know is that warming becomes more dangerous once it exceeds two degrees, and that the less the climate changes, the better it is for us. So we have to do everything we can to minimize climate change.”

The Chairman of the Nobel Committee for Physics, Thor Hans Hansson reached out to policymakers around the world to announce this year’s awards. He is not sure whether they will finally understand the warnings about climate change if the Nobel Committee points them out. In any case, it is certain “that the climate models are solidly based on physics theory”.

Manabe shares half of the prize money with Klaus Hasselmann (total 985 000 Euro), the other half goes to Giorgio Parisi.
