When science meets art: The birth of a new mindset

by Merlijn Twaalfhoven

Composer Merlijn Twaalfhoven co-created the IIASA session: Courage – A dance science performance debate about sustainable futures by Gloria Benedikt who leads the Art and Science Project at IIASA, at the EuroScience Open Forum in Toulouse. He tells us more about how this merging of worlds can create new bridges between art, science, and societal issues.

An urgent need for better questions

There I was, an artist invited to the largest conference on science and innovation in Europe – the EuroScience Open Forum, commonly referred to as ESOF. Amidst showcases and lectures about robotics, space exploration, and gene technology, I could share my ideas about the connection between art and science.

This topic can easily become filled with abstractions or generalities. It is true that science and art are both about creativity and research, but is there a concrete way for them to find each other? Is there urgency to bridge these two worlds? The answer to both these questions is a resounding yes.

Different eyes

Art and science are like children that always loved to play together. The worlds of both are filled with curiosity, take steps into the unknown, and embrace uncertainty and adventure. Both are not satisfied with the answers that are provided, and keep asking questions – obsessed with what is below the surface, beyond the horizon, and beneath the solid ground of our convictions.

These two children have much in common, yet they have different eyes, they see things differently. While observing the same world, they pose different questions.

One would ask, ‘What is this?’, ‘How did it become this way?’ and ‘Why is this the way it is?’ While the other asks, ‘What might this also be?’, ‘How can we see this differently?’ and ‘What will this be if…?’

Art and science have always learned and grown together, but over the last few centuries, they have started to grow more and more apart. We might say they have grown up. They each developed their curiosity and creativity into diligent practices and professional attitudes, and started to work within strict disciplinary boundaries. The playfulness and free experimenting sadly transformed into competition and a fixation on what they call “excellence”.

Who is asking the questions?

Today, while global warming, inequality, digitalization, and migration bring instability and change to our societies and global mindsets, there is an urgent need for answers, reliability, and guidance.

Leaders of all kinds, including artists that might influence the way we feel and scientists that might direct the way we reason, are pressed to give such answers. We all add our answers to platforms and channels of news, opinion, soundbites, and statements. It is a cacophony. A flood without structure.

Nevertheless, do we actually know who is asking the questions? Is it the entertainers, talk show hosts, and commercial news media? Will we let the most dominant voices define the big questions of our time? Or can we bring better questions built on the observations, insights, and intuition of artists and scientists to the surface?

Show, don’t talk

We know what the big challenges in society are, and the urgent steps needed to prevent catastrophic global warming, societal polarization, and mass migration are well defined. But how do we, as curious, experienced, and highly trained artists, scientists, researchers, and explorers join forces to make the urgent and engaging questions become not just loud and clear, but part of everybody’s daily reality? Can we not just write or talk about warnings and concerns, but rather create and build questions that ask for a vision that is attractive and beautiful – a way forward that we can experience directly and that makes all of us want to make the world great again?

Beauty

A first step is to find beauty in the world around us. Instead of asking, ‘Why are these people poor?’ we can ask, ‘What makes you proud?’ Instead of asking, ‘How do we stop people from buying cars?’ we can ask, ‘How can I relieve you from the burden of owning (cleaning, insuring, repairing) a car?’ Instead of asking, ‘Why are people unhealthy?’ we can ask, ‘When do you feel free of stress?’

Imagination

A second step is to design ways to express this beauty and to imagine new possibilities. How can we show others the pride you feel? What is the value you get when you do not own a car? What does a stress-free moment sound like?

Play

A third step is to connect people to a changing and evolving reality in playful and challenging ways. What makes your pride contagious to others? How do we practice freedom from possessions? How do we build moments of stress-free time into a rhythm?

These are only a few examples of how art can expose beauty in urgent research topics, create forms of expression to give new ideas presence, and build living and changing structures where a new scientific/artistic mindset may flourish.

What will be the laboratories in which we develop and explore new questions? When will these grownups – art and science – decide to approach each other again, remember their playful childhood, and fall in love all over again? It might be a fruitful affair and give birth to a new mindset that can help us face today’s challenges.

How to achieve scientific excellence

W. Brian Arthur from the Santa Fe Institute (SFI), and a former IIASA researcher, talks about increasing returns and the magic formula to get really great science.

Recently, Brian stopped in at the Complexity Science Hub Vienna, of which IIASA is a member institution, and spoke to Verena Ahne about his work.

Brian, now 71, is one of the most influential early thinkers of the SFI, a place that without exaggeration could be called the cradle of complexity science.

Brian became famous with his theory of increasing returns. An idea that has been developed in Vienna, by the way, where Brian was part of a theoretical group at the IIASA in the early days of his career: from 1978 to 1982.

“I was very lucky,” he recalls. “I was allowed to work on what I wanted, so I worked on increasing returns.”

The paper he wrote at that time introduced the concept of positive feedbacks into economy.

The concept of “increasing returns”

Increasing returns are the tendency for that which is ahead to get further ahead, for that which loses advantage to lose further advantage. They are mechanisms of positive feedback that operate—within markets, businesses, and industries—to reinforce that which gains success or aggravate that which suffers loss. Increasing returns generate not equilibrium but instability: If a product or a company or a technology—one of many competing in a market—gets ahead by chance or clever strategy, increasing returns can magnify this advantage, and the product or company or technology can go on to lock in the market.”

(W Brian Arthur, Harvard Business Review 1996)

This was a slap in the face of orthodox theories which saw–and some still see–economy in a state of equilibrium. “Kind of like a spiders web,” Brian explains me in our short conversation last Friday, “each part of the economy holding the others in an equalization of forces.”

The answer to heresy in science is that it does not get published. Brian’s article was turned down for six years. Today it counts more than 10.000 citations.

At the latest it was the development and triumphant advance of Silicon Valley’s tech firms that proved the concept true. “In fact, that’s now the way how Silicon Valley runs,” Brian says.

The youngest man on a Stanford chair

William Brian Arthur is Irish. He was born and raised in Belfast and first studied in England. But soon he moved to the US. After the PhD and his five years in Vienna he returned to California where he became the youngest chair holder in Stanford with 37 years.

Five years later he changed again – to Santa Fe, to an institute that had been set up around 1983 but had been quite quiet so far.

Q: From one of the most prestigious universities in the world to an unknown little place in the desert. Why did you do that? 

A: In 1987 Kenneth Arrow, an economics Nobel Prize winner and mentor of mine, said to me at Stanford: We’re holding a small conference in September in a place in the Rockies, in Santa Fe, would you go?

When a Nobel Prize winner asks you such a question, you say yes of course. So I went to Santa Fe.

We were about ten scientists and ten economists at that conference, all chosen by Nobel Prize winners. We talked about the economy as an evolving complex system.

Veni, vidi, vici

Brian came – and stayed: The unorthodox ideas discussed at the meeting and the “wild” and free atmosphere of thinking at “the Institute”, as he calls the Santa Fe Institute (SFI), thrilled him right away.

In 1988 Brian dared to leave Stanford and started to set up the first research program at Santa Fe. Subject was the economy treated as a complex system.

Q: What was so special about SF?

A: The idea of complexity was quite new at that time. But people began to see certain patterns in all sorts of fields, whether it was chemistry or the economy or parts of physics, that interacting elements would together create these patterns…To investigate this in universities with their particular disciplines, with their fixed theories, fixed orthodoxies–where it is all fixed how to do things–turned out to be difficult.

Take the economy for example. Until then people thought it was in an equilibrium. And there we came and proved, no, economics is no equilibrium! The Stanford department would immediately say: You can’t do that! Don’t do that! Or they would consider you to be very eccentric…

So a bunch of senior fellows at Los Alamos in the 1980s thought it would be a good idea if there was an independent institute to research these common questions that came to be called complexity.

At Santa Fe you could talk about any science and any basic assumptions you wanted without anybody saying you couldn’t or shouldn’t do that.

Our group as the first there set a lot of this wild style of research. There were lots of discussions, lots of open questions, without particular disciplines… In the beginning there were no students, there was no teaching. It was all very free.

This wild style became more or less the pattern that has been followed ever since. I think the Hub is following this model too.

The magic formula for excellence

Q: Was this just a lucky concurrence: the right people and atmosphere at the right time? Or is there a pattern behind it that possibly could be repeated?

A: I am sure: If you want to do interdisciplinary science – which complexity is: It is a different way of looking at things! – you need an atmosphere where people aren’t reinforced into all the assumptions of the different disciplines.

This freedom is crucial to excellent science altogether. It worked out not only for Santa Fe. Take the Rand Corporation for instance, that invented a lot of things including the architecture of the internet, or the Bell Labs in the Fifties that invented the transistor. The Cavendish Lab in Cambridge is another one, with the DNA or nuclear astronomy…

The magic formula seems to be this:

  • First get some first rate people. It must be absolutely top-notch people, maybe ten or twenty of them.
  • Make sure they interact a lot.
  • Allow them to do what they want – be confident that they will do something important.
  • And then when you protect them and see that they are well funded, you are off and running.

Probably in seven cases out of ten that will not produce much. But quite a few times you will get something spectacular – game changing things like quantum theory or the internet.

Don’t choose programs, choose people

Q: This does not seem to be the way officials are funding science…

A: Yes, in many places you have officials telling people what they need to research. Or where people insist on performance and indices… especially in Europe, I have the impression, you have a tradition of funding science by insisting on all these things like indices and performance and publications or citation numbers. But that’s not a very good formula.

Excellence is not measurable by performance indicators. In fact that’s the opposite of doing science.

I notice at places where everybody emphasize all this they are not on the forefront. Maybe it works for standard science; and to get out the really bad science. But it doesn’t work if you want to push boundaries.

Many officials don’t understand that.

In Singapore the authorities once asked me: How did you decide on the research projects in Santa Fe? I said, I didn’t decide on the research projects. They repeated their question. I said again, I did not decide on the research projects. I only decided on people. I got absolutely first rate people, we discussed vaguely the direction we wanted things to be in, and they decided on their research projects.

That answer did not compute with them. They are the civil service, they are extraordinarily bright, they’ve got a lot of money. So they think they should decide what needs to be researched.

I should have told them – I regret I didn’t: This is fine if you want to find solutions for certain things, like getting the traffic running or fixing the health care system. Surely with taxpayer’s money you have to figure such things out. But you will never get great science with that. All you get is mediocrity.

Of course now they asked, how do we decide which people should be funded? And I said: “You don’t! Just allow top people to bring in top people. Give them funding and the task of being daring.”

Any other way of managing top science doesn’t seem to work.

I think the Hub could be such a place – all the ingredients are here. Just make sure to attract some more absolutely first rate people. If they are well funded the Hub will put itself on the map very quickly.

Parched: The war for water in Mexico City

By Parul Tewari, IIASA Science Communication Fellow 2017

Mexico City has been experiencing a major water crisis in the last few decades and it is only getting worse. To keep the water flowing, the city imports large amounts of water from as far as 150 kilometers.

Not only is this energy-intensive and expensive, it creates conflict with the indigenous communities in the donor basins. Over the last decade, a growing number of these communities have been protesting to reclaim their rights to water resources.

As part of the 2017 Young Scientists Summer Program at IIASA, Francine van den Brandeler studied the struggle that Mexico City is facing as it tries to provide water to its growing population and expanding economy. Local aquifers have been over-exploited, so water needs to be imported from distant sources, with high economic, social, and environmental impacts. Van den Brandeler’s study assesses the effectiveness of water use rights in promoting sustainable water use and reducing groundwater exploitation in the city.

“A few centuries back, Tenochtitlan, the place where Mexico City stands today, was known as the lake city,” says Van den Brandeler. The Aztecs had developed a sophisticated system of dikes and canals to manage water and mitigate floods. However, that changed quickly with the arrival of the Spaniards, who transformed the natural hydrology of the valley. As the population continued to grow over the next centuries, providing drinking water became an increasing challenge, along with controlling floods. As the lake dried up, people pumped water from the ground and built increasingly large infrastructure to bring water from other areas.

Communities from lower-income groups, living in informal settlements on the outskirts of the metropolitan region are more vulnerable to this scarcity. Many live on just few liters of water every day, and do not have access to the main water supply network, instead relying on water trucks which charge several times the price of water from the public utility.

“In wealthier areas people consume much more than the average European does every day. It is a question of power and politics,” says van den Brandeler. “The voices of marginalized communities go unheard.”

The more one learns about the situation, the more complicated it becomes. The import of water started in the 1940’s. But with a massive increase in population in the last couple of decades, the deficits have become much worse.

The government’s approach has been to find more water rather than rehabilitating or reusing local surface and groundwater sources, or increasing water use efficiency, says van den Brandeler. Therefore wells are being drilled deeper and deeper—as much as 2000 meters into the ground—as the water runs out.

Some people have started initiatives to harvest rainwater, but it is not considered a viable solution by those in charge. “A lot of it has to do with their worldview and general paradigm. The people working at the National Water Commission and the Water Utility of Mexico City have been trained as engineers to make large dams and put pipes in the ground. They don’t believe in small-scale solutions. In their opinion when millions of people are concerned, such solutions cannot work,” says van den Brandeler.
Although the city gets plenty of rain during the rainy season, it goes directly into the drainage system which is linked to the sewage system. This contaminates the water, making it unusable. At the same time, almost 40% of the water in Mexico City’s piped networks is lost due to leakages.

Policy procedures and institutional functioning also remain top-down and opaque, van den Brandeler has found. One of the policy tools for curbing excess water use are water permits for bulk use, for agriculture, industry, or public utilities supplying water. Introduced in the 1940s, lack of proper enforcement has created misuse and conflicts.
For example, while farmers also require a permit that specifies the volume of water they may use each year, they do not pay for their water usage. However, it is difficult to monitor if farmers are extracting water according to the conditions in the permit. Since they do not pay a usage fee, there is also less incentive for the National Water Commission to monitor them. As a result, a huge black market has cropped up in the city where property owners and commercial developers pay exorbitant prices to buy water permits from those who have a license. Since the government allows the exchange of permits between two willing parties, they make it appear above-board. However, it has contributed to the inequalities in water distribution in the city.

With the water crisis worsening every year, Mexico City needs to find a solution before it runs out of water completely. Van den Brandeler is hopeful for a better future as she studies the contributing factors to the problem. She hopes that the water use permits are better enforced and users are given stronger incentives to respect their allocated water quotas. Further, if greater efforts are made within the metropolis to repair decaying infrastructure and scale up alternatives such as rainwater harvesting and wastewater reuse, the city won’t have to look at expensive solutions if adopted in a decentralized manner.

About the Researcher

Francine van den Brandeler is a third year PhD student at the University of Amsterdam in Netherlands. Her research is on the spatial mismatches between integrated river basin management and metropolitan water governance – the incompatibility of institutions and biophysical systems-, which can lead to fragmented water policy outcomes. Fragmented decision-making cannot adequately address the issues of sustainability and social inclusion faced by megacities in the Global South. She aims to assess the effectiveness of policy instruments to overcome this mismatch and suggest recommendations for policy (re)design. At IIASA she was part of the Water Program and worked under the supervision of Sylvia Tramberend and Water Program Director Simon Langan.

Myths are not true… or are they?

By Gerid Hager, IIASA Ecosystems Services and Management Program

©Gerid Hager | IIASA

In July, Miranda Lakerveld, a music drama artist and founder of the World Opera Lab, visited IIASA to run two storytelling workshops with young actors in civil society and youth policy, as well as with YSSP students and IIASA staff. Miranda first came to IIASA in September 2016 as part of the Citizen Artist Incubator.

After the workshops in July, Miranda and I sat down for a chat.

Gerid: Miranda, in the workshop you shared how you approach storytelling in your artistic practice. You said: “I’m looking for moments that feel true, I pick them up and weave them together into new stories.” Then, a participant exclaimed: “Stories are not true!” It seems a contradiction, but possibly this is the very nature of stories. They might not be true, giving accurate accounts of past events, but they carry truths in them, which we so often can’t capture otherwise. You’ve been working with myths for a long time: What value do you see in them today, as we’re trying to navigate between “alternative facts” and often incomprehensible scientific writing?

Miranda: Yes, this was a short reflection on the methodology I have developed and applied in many different contexts over the last eight years. It uses comparative mythology as a starting point. The aim of the method is to create a meaningful creative exchange that can involve people from all walks of life. Myths are examined from the perspectives of different cultures, and through this intercultural lens, we find symbols and archetypes that resonate as ‘true across cultures.

The ‘post-truth’ era made us extra aware of the divides between communities and I believe such an embodied practice of mythology can be an inspiring place for people to meet. I think the renunciation of facts and scientific insight is a symptom of people feeling left out and angry. Using myths and stories can be one way to bring people together and find common truths.

This workshop was part of the Systems Thinking for Transformation project and we wanted to search for “systems stories” in ancient narratives. We arrived at a very personal story of endurance and adaptation, pondered the power of great nature and cyclical behavior on a very large scale, and discussed economic justice and its relation to sustainable development. How does one story from Greek mythology – the Hymn to Demeter – lead to such diverse considerations?

The development of myths and folk stories has very specific characteristics, which I like to compare to ecosystems. Symbols and characters create organisms in constant interaction with their environments. Through time, myths change, in fertile circumstances the stories flourish, and layers of meaning are added.

Participants relate the Greek myth to myths from their own cultural backgrounds, and then to their personal histories. Interestingly, in the encounter between the myth and a group, some deeply felt preoccupations spring up from under the surface. I am still not sure how this happens. It probably has to do with a combination of embodiment of the characters, the richness of the archetypes, and the mise en scène, which represents the people inside the larger system.

One integral part of systems thinking is to be able to consider and explore multiple perspectives on a problem or situation. How does the embodiment exercise come in to this?

Slipping into different characters from the story is an essential part of the process. It unlocks the creative imagination and is related to action in society. The Greek root-word for drama is “dran”, which means “to act”. Through embodiment we can take the position of another character or force in the system. The performing arts make this possible: we can take on different roles, understand new parts, and at the same time experience the whole system from a new perspective.

There are other examples of how art and science meet through storytelling. A researcher at Berkeley University teamed up with story artists from PIXAR to help researchers create better stories about their research. What interests you in working with scientists and what is the role of storytelling?

I think the collaboration between art and science could go far beyond creating stories about research. We see very different approaches of creating and transmitting knowledge. So we have to deal with this tension but an inclusive society also means we should value these differences. The academic world has created an intricate system of validating knowledge leading to very specialized fields of research. Artists work on larger ideas, but the output cannot necessarily be validated. We are trying to grasp truths about the same river, but we work from opposite river banks. I think we can build bridges and increase our ability for insight and action by telling stories together.

Bringing satellite data down to Earth

By Linda See, IIASA Ecosystems Services and Management Program

Satellites have changed the way that we see the world. For more than 40 years, we have had regular images of the Earth’s surface, which have allowed us to monitor deforestation, visualize dramatic changes in urbanization, and comprehensively map the Earth’s surface. Without satellites, our understanding of the impacts that humans are having on the terrestrial ecosystem would be much diminished.

Over the past decade, many more satellites have been launched, with improvements in how much detail we can see and the frequency at which locations are revisited. This means that we can monitor changes in the landscape more effectively, particularly in areas where optical imagery is used and cloud cover is frequent. Yet perhaps even more important than these technological innovations, one of the most pivotal changes in satellite remote sensing was when NASA opened up free access to Landsat imagery in 2008. As a result, there has been a rapid uptake in the use of the data, and researchers and organizations have produced many new global products based on these data, such as Matt Hansen’s forest cover maps, JRC’s water and global human settlement layers, and global land cover maps (FROM-GLC and GlobeLand30) produced by different groups in China.

Complementing Landsat, the European Space Agency’s (ESA) Sentinel-2 satellites provide even higher spatial and temporal resolution, and once fully operational, coverage of the Earth will be provided every five days. Like NASA, ESA has also made the data freely available. However, the volume of data is much higher, on the order of 1.6 terabytes per day. These data volumes, as well as the need to pre-process the imagery, can pose real problems to new users. Pre-processing can also lead to incredible duplication of effort if done independently by many different organizations around the world. For example, I attended a recent World Cover conference hosted by ESA, and there were many impressive presentations of new applications and products that use these openly available data streams. But most had one thing in common: they all downloaded and processed the imagery before it was used. For large map producers, control over the pre-processing of the imagery might be desirable, but this is a daunting task for novice users wanting to really exploit the data.

This slideshow requires JavaScript.

In order to remove these barriers, we need new ways of providing access to the data that don’t involve downloading and pre-processing every new data point. In some respects this could be similar to the way in which Google and Bing provide access to very high-resolution satellite imagery in a seamless way. But it’s not just about visualization, or Google and Bing would be sufficient for most user needs. Instead it’s about being able to use the underlying spectral information to create derived products on the fly. The Google Earth Engine might provide some of these capabilities, but the learning curve is pretty steep and some programming knowledge is required.

Instead, what we need is an even simpler system like that produced by Sinergise in Slovenia. In collaboration with Amazon Web Services, the Sentinel Hub provides access to all Sentinel-2 data in one place, with many different ways to view the imagery, including derived products such as vegetation status or on-the-fly creation of user-defined indices. Such a system opens up new possibilities for environmental monitoring without the need to have either remote sensing expertise, programming ability, or in-house processing power. An exemplary web application using Sentinel Hub services, the Sentinel Playground, allows users to browse the full global multi-spectral Sentinel-2 archive in matter of seconds.

This is why we have chosen Sentinel Hub to provide data for our LandSense Citizen Observatory, an initiative to harness remote sensing data for land cover monitoring by citizens. We will access a range of services from vegetation monitoring through to land cover change detection and place the power of remote sensing within the grasp of the crowd.

Without these types of innovations, exploitation of the huge volumes of satellite data from Sentinel-2, and other newly emerging sources of satellite data, will remain within the domain of a small group of experts, creating a barrier that restricts many potential applications of the data. Instead we must encourage developments like Sentinel Hub to ensure that satellite remote sensing becomes truly usable by the masses in ways that benefits everyone.
