Painting Energies - Artscience podcast by Aalto University

About Painting Energies - Artscience podcast by Aalto University

Painting Energies is a podcast about light, colour, plants, microbes, and electrical energy. Eleven conversations with invited guests explore their relations, and our relations to them, through a dialogue across science, technology, art and philosophy. The topics of the conversions emerge from a trandiscplinary artscience research process that took place in Aalto University since 2017 and led to creation of a unique solar panel painting. In the artwork, plant-based colorants hand-painted on glass convert light to electricity while interpreting the colours and patterns of an iconic painting by J.M.W. Turner. In the process of making and thinking, we came across many observations and questions that we wish to share with you through moments of focus and joyful reflection. The podcast is hosted by Janne Halme (physicist) and Bartaku (artist researcher). Learn more about the episodes and guests in: https://www.aalto.fi/en/podcasts/painting-energies-podcast

   #9 Planting empathy - with Janet Laurence

   In this episode, we talked to the Australian installation artist Janet Laurence. Janne met her when he was a visiting fellow at the University of New South Wales in Sydney. Janet's practice focuses on creating immersive experiences that bring people into an intimate relationship with nature. She is known for her work with plants, which highlights not only their beauty but also their fragility and the need for care and empathy to protect the environment. Her work is diverse, spanning from large-scale installations in forests and ecosystems, to sculptures, and even video and sound pieces. Entangled Garden for Plant Memory, Yu-Hsiu Museum, Taiwan (2020), After Nature, Museum of Contemporary Art, Sydney, Australia (2019), and Deep Breathing: Resuscitation for the Reef, Musée National d’Histoire Naturelle, Paris, France (2015) are recent examples of her work and exhibitions that relate to our conversation. Janet tells about her way of working with scientists and researchers, and about her art installations consisting of samples from the vast animal and plant collections of natural history museums. We discuss the controversial feelings they evoke at the border between life and death, preserved but lost. Janne wonders if living nature itself is, to sapiens, like a natural history museum: a collection of increasingly rare species preserved at the brink of extinction. Janet and Bart share their views on the role of art: could it be conceived as a powerful tool for behavioural change? This leads us to compare the different approaches by scientists and artists in presenting work and questioning: one obsessed in finding answers and solutions, the other avoiding them at all cost; the art of enquiry. We end the conversation with Janet telling about her upcoming work with researchers of the Antarctic, spells for weather, and the plants in her new garden.

   #8 Cross-disciplinary biotopes - with James Evans

   What are the ingredients for a successful cross-disciplinary collaboration? We think one of them is an evolving biotope where playful experimentations and collisions across research fields are actively encouraged and supported. And you also need persons that act as catalysts and linking agents. Like James Evans, our guest in this episode. James is a microbiologist and lab manager at Aalto University – first at Biofilia, Lab for Biological Arts and now at Biogarage. Before, he worked at Biokeskus, University of Helsinki, and at the VTT Technical Research Centre of Finland. We discuss the role of dynamic cross-disciplinary lab environments in a knowledge institute. How are they combining art, design, science, and engineering in research and education? How is James actively guiding the intertwining of these differing worlds? How do transversal collaborations start and evolve? In the conversation, James outlines the requirements for a creative collaborative (work)flow and environment involving experts and students. Transdisciplinary research is done also elsewhere, but James says that “here in Aalto, the jumps [across the discipline borders] are much longer, and people are much more open to doing this kind of thing here. I think that’s very important for this type of work. I can’t imagine any other circumstance where you can get real artistic production done in a functional academic lab.” Staff members like James are well positioned to connect previously separate practices and disciplines. They receive project and experimentation requests from students from science, art, design, and architecture, separately or in groups, and facilitate workshops or contribute to those hosted by experts. This way, they often have to make a new brew from existing procedures from different disciplines, often with the unorthodox use of tools and materials. Open creative labs and their lab managers are key nodes of evolving creativity. Our conversation goes through roughly four chapters: 0:00- Art-science Biolab at Aalto University 24:10- Example of research: Purifying microbial colour in the context of artistic use of solar energy 33:35- The enigmatic pH: its role in viruses and in the applying of biocolour; Defining life/non-life/synthetic life. 44:35- What are the qualities of a good cross-disciplinary biotope?

   #7 Seeing at the limit of extreme darkness - with Petri Ala-Laurila

   In its first public exhibition, we connected `Blck Vlvt´ with a blue wire to an LED in a dark room. There, it faintly lit up a small part of a canvas print of JMW Turner's `Snow Storm …´– the painting that `Blck Vlvt´ interprets. Viewing it in that dim light, visitors reported visual sensations that interested us in learning more about how human vision works in the dark. This question belongs to the research field of Petri Ala-Laurila, who joined us for a lively conversation about the fascinating topic. Petri is an Associate Professor in Biophysics at the Department of Neuroscience and Biomedical Engineering at Aalto University and the University of Helsinki (Ala-Laurila Lab). In this episode, we seek to understand what happens physiologically in the eye-brain system and cognition-wise in the human mind when that human is experiencing an artwork. How does sapiens' vision work in the limit of extreme darkness – a phenomenon familiar to all by experience but mysterious to science? Is it possible to see a single photon? What is the dimmest shadow we can see? How is the eye doing visual computations, being part of the brain? How do hormones, emotions, and other senses affect what we see? Petri leads us to the path of the neural signals from the retina to the brain and cognition and a riverbank in Lapland where he goes fly-fishing for salmon every year. We hear about his visions for making good and bold science, practicing open scientific collaboration, working across disciplines, and the immersive moments of measuring neural signals of the live retina alone in a dark lab. The first part of the conversation deals with the neurophysiology of vision, and from 54:25 on, we move to the overarching topics and personal reflections.

   #6 Old stubborn tensions: the work(ings) and the about(ings) - with Alexandra Wettlaufer

   In this episode, our guest is Professor of French and Comparative Literature Alexandra K. Wettlaufer (University of Texas and Austin, College of Liberal Arts). She specializes in 19th-century literature, visual arts, culture, and gender studies and has written various books on these topics*. It is in particular her paper `The Sublime Rivalry of Word and Image: Turner and Ruskin Revisited´ that ignited our conversation. Alexandra explains how Turner was trying to reproduce the experience of seeing and feeling, rather than reproducing the topography or an image. He was very much about what was not there. That we have to add to it our own imagination to bring it closer to the way we experience the world. Through his paintings, like Snowstorm…, Turner and many contemporaries wanted to translate a feeling into a certain context. Not to show what was there, but to evoke a feeling in the viewer. A shift away from the Cartesian ideas of knowledge, to Locke and the idea of experience. In the first half of the 20th Century that was an important shift in the aesthetic and scientific language and ethos. So, what the artists wanted to do was to find a way to evoke or invoke in the reader or viewer an experience that is at once individual and universal. Baudelaire said about one of Delacroix‘ paintings that you can stand so far away that you can’t see what the painting is representing. But you still understand it because the colours are giving you the feeling. Alexandra thinks that is exactly what Turner is doing in his paintings that are not highly representative. This tension between the artwork and the use of language in and around it is still very contemporary, an ever-spinning thread in many art_science, art communication, and curatorial practices. Alexandra stresses the importance of how art represents and disrupts hegemonic forces and powers. She likes disrupters like Turner, who wanted to make us see in different ways. As did women artists, as did Baudelaire. It is Innovation, it is the movement against what is expected. It looks like a mess. We learn to see, that is the other thing, seeing is learned, and it is a discipline. Janne adds that it is similar in science: there is accepted science, and then you have those who are crazy enough to think and do entirely differently, against the rules. * References in the conversation Wettlaufer, Alexandra K.

   #5 Electrical cable bacteria - with Robin Bonné

   In this episode, we meet physicist Robin Bonné. In his Ph.D. research, Robin tried to combine the fundamentals of physics with living creatures. They are called micro-organisms, but they don’t look very micro – once Robin saw them with his naked eye. They are filamentous bacteria, with a lot of interdependent cells all in one chain, up to seven centimeters long, growing from the Earth's surface down into the soil where they find their main food, hydrogen sulfide. They are called cable bacteria since they became of interest to scientists in 2012. Since their discovery on the coasts of Denmark, these bacteria are found in many sediments around the world, ranging from seawater biotopes to lakes and maybe even the pond in your local park. The cable bacteria have an ability that is quite unknown in nature: they have cells that do only half of the metabolic processes. Some cells do one half, others the other half and the halves are connected by conduction of electrons. It was presumed that the cable-like bacterium can conduct electrons from one cell to another, from the oxygen-poor bottom part where electrons are taken from the food, up to the top cells where electrons are needed, passed on to oxygen. In 2017, Robin and collaborators found that cable bacteria indeed conduct electricity. This electron transport takes place in the centimeter range, which is three orders of magnitude longer than was known before (in Geobacter nanowires). Robin did research into how this electron transport occurs. The cable bacteria have tiny conductive wires just underneath their surface. What they are made of – proteins perhaps – is unknown, and this question is the holy grail in that research field now. How are cable bacteria like plants, connecting the world above ground to the world below ground and signaling between them? And do they also have a relation to sunlight like plants do? Could they be used as electrical conductors in our painted solar cells? Trying to understand cable bacteria requires many disciplines: physics, chemistry, biology; engineering. Our conversation with Robin embraces these fields and tiptoes also into the philosophy of science and the use of bacteria in wastewater treatment and bioelectronics.

   #4 Between art and science - with Laure-Emmanuelle Perret-Aebi

   In this episode you hear scientist Laure-Emmanuelle Perret-Aebi in conversation with Janne and Bart. Trained as a theoretical chemist she turned to applied science working for EPFL and CSEM (Switzerland) in the field of photovoltaics. As such, she contributed to the Solar Impulse project (Bertrand Picard) and to improving the aesthetics of solar panels for building integration ”so that people would start to love it too”. To further connect with society, she founded Compáz, a collective of scientific and artistic skills, and an incubator of ideas that assist social progress and question big ideas about society. Compáz has made creative PV projects like photo-integrated solar panels, that have been exhibited worldwide. We talk about installing solar energy technology in an urban context vs in a landscape (desert); the difference between industrial and architectural PV where the aesthetics are more important than efficiency, the tensions that this brings about, and the new vocabulary, skills, and education required, to increase the chances on successful dialogue in a multidisciplinary context. Laure shares her views about the role of technology in the context of the big challenges of these times: the problems are quite well defined, but solutions are not. ”Technology is only part of the solution. New models for the economy, the way of living together, … but also art, music, and photography are part of the solution.” - Laure We identify the need to determine problems together with younger generations, and the importance of re-acknowledging that humankind is part of nature – the way how the SARS‑CoV‑2 virus situation is being handled illustrates the issue, separating it from the climate crisis, whereas both are linked. We discuss if and how the underlying worldviews are communicated to the audiences. And the challenges in artscience projects. Laure encourages the listers to find their own way in career path(ing), and for daring (also risking) to venture away from the artificial separations between the common professional disciplines – intricately interwoven in existence/reality as they are in the end. "You don't need to fit into a group. You can be between, that's fine. Just make your own place. "

   #3 Sunlit leaves - with Matthew Robson

   In this episode we spend a sunny afternoon in Viikki Arboretum with Dr. Matthew Robson. Matthew is teaching and studying plant ecophysiology in the Viikki Plant Science Centre. His research group studies how plants respond to changes in the spectral composition of radiation, in particular in the forest understorey. Our wonderful walk through the sunlit, bird-filled forest takes us from one biotope to another, and our conversation from the molecular to the global scale. Matthew tells us about the fascinating ways how plants respond to the constantly varying light conditions under the forest canopy using their molecular “light antennas”. How do plants pick up the illumination signals from the enviroment and use them as cues for physiological responses – do they have a clock and a notebook in their leaves? What other functions do various pigments in the leaves of the plants have? And why the leaves at the top of the canopy are thicker than the ones on the lower parts? Moving to the global scale, we discuss how the cloud formation as part of climate change might impact photosynthesis in the forest canopies. How do plants respond to the fast changes in the environment in the short term and over the generations? Why some plants are chocen by humans to be adjusted to (saved from) climate change? Matthew also tells about possible ways to improve photosynthesis of crop plants as part of carbon capture efforts – and responds to the solar physicist who mistakenly calls leaves inefficient. What solar cells and leaves have in common, and why are they still far from being leaf-like? Is it worth to try to reproduce nature? Adding the human perspective, we discuss among many things how scientists in Matthew's field speak about colours, which turns out to be an ongoing spectral debate. The shadows of the trees growing longer, we end the walk learning how dead leaves are colorfully alive.

   #2 Colour - with Sini Vihma

   In this episode we meet visual artist Sini Vihma. Sini teaches theory and practice in colour and perception in the Department of Art in Aalto University with focus on contemporary art, particularly painting. She is a board member of Finnish Colour Association. Our conversation with Sini meanders through many aspects of human color perception from the technical and scientific to the biological, physiological, and psychological as well as philosophical. What is colour brightness, lightness, contrast, gamut, saturation, and hue? How do the properties of the light, the object and its surroundings, and the viewer affect the colour perception? How does Sini teach these topics? We ponder do humans remember colors well. And how can('t) an artist ensure that her colors look the same in a gallery as they did in her studio. Janne learns about the concept of local color and how people differ in their sensitivity to see it; Sini is amazed about the Blck Vlvt solar cell painting technique. Sini tells how she became a painter and a teacher and how her relationship with colour developed over the years; Bart talks about his present-in-the-moment when painting the cells, and his corresponding approach to artscience practice overall - his intention to create biotopes where beautiful coincides can happen.

   #0 Introducing - with Janne Halme and Bartaku

   In this episode the hosts Janne Halme and Bartaku introduce themselves and the podcast. They tell about the co-creation process that led to the podcast, and exchange thoughts, wishes and expectations about the forthcoming episodes. Bartaku tells how he got the inspiration for working with the plant Aronia melanocarpa, why he calls it Baroa Belaobara and the berryapple, and how its connection to the iconic painting by JMW Turner emerged. We hear about the poetic aspects that pulled Bartaku to work with the plant and how the Aamo artsience group formed. Janne tells how he started working on dye-sensitized solar cells, what motivated him to study them as a physicist, and how he learn the craft of making and measuring the cells. In the conversation, Janne asks Bartaku how he felt about working with the more technological version of the solar cell, and Bartaku asks Janne how his colleagues have perceived his collaboration with an artist. The hosts anticipate some of the topics for the forthcoming episodes, including the notion of `bio´ solar cell, the use of plant-based colorants in the solar cell, and the function of the human visual system and the perception of colours. In a broader perspective, they wish to converse with their guests on the poetic, aesthetic and bioethical aspects of technology, and the institutional and administrative conditions required for successful art-science collaboration. The discussion complements this 15 min video documentary film - the hosts warmly invite you to view it here: https://www.youtube.com/watch?v=r6PZ-1iJpAY You can learn more about the podcast and the hosts here: https://www.aalto.fi/en/podcasts/painting-energies-podcast

    #1 Dye-sensitized solar cells - with Anders Hagfeldt

    In this episode, our guest is Professor Anders Hagfeldt. Anders is considered one of the world’s leading researchers in dye-sensitized solar cells. By developing new synthetic dyes and electrolyte reduction-oxidation pairs and studying their function at the molecular scale, his research teams have significantly improved the efficiency of dye solar cells and the understanding of how they work. He is currently Vice-Chancellor of Uppsala University and Professor of Physical Chemistry. In 2005 Janne worked as a visiting doctoral student in Anders's research group at KTH in Stockholm, where he learned the craft of making and measuring dye solar cells better. In the episode we hear what made Anders interested in photoelectrochemistry and become a PhD student, and how he learned to build dye solar cells at EPFL in Switzerland under Michael Grätzel and Brian O’Regan in 1990 - at the time of their breakthrough discovery of the modern dye-sensitized solar cell. We discuss why synthetic dyes more durable than natural dyes and how the solar cell protects them from degradation by light. We share stories about how inspiring and rewarding it is to make solar cells with your own hands, and discuss how scientific breakthroughs are most often made, what accidental discoveries he and his team has made, and where does the dye-sensitized solar cell technology stand today? Among many other things, we ponder why combining scientific and artistic careers is difficult, how the creativity of young researchers can best be supported, and what research and improvisation music have in common.
