Scientific Models : Red Atoms, White Lies and Black Boxes in a Yellow Book
- 2016
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- A zebrafish, the hull of a miniature ship, a mathematical equation and a food chain - what do these things have in common? They are examples of models used by scientists to isolate and study particular aspects of the world around us. This book begins by introducing the concept of a scientific model from an intuitive perspective, drawing parallels to mental models and artistic representations. It then recounts the history of modelling from the 16th century up until the present day. The iterative process of model building is described and discussed in the context of complex models with high predictive accuracy versus simpler models that provide more of a conceptual understanding. To illustrate the diversity of opinions within the scientific community, we also present the results of an interview study, in which ten scientists from different disciplines describe their views on modelling and how models feature in their work. Lastly, it includes a number of worked examples that span different modelling approaches and techniques. It provides a comprehensive introduction to scientific models and shows how models are constructed and used in modern science. It also addresses the approach to, and the culture surrounding modelling in different scientific disciplines. It serves as an inspiration for model building and also facilitates interdisciplinary collaborations by showing how models are used in different scientific fields. The book is aimed primarily at students in the sciences and engineering, as well as students at teacher training colleges but will also appeal to interested readers wanting to get an overview of scientific modelling in general and different modelling approaches in particular.

EP9 Starlight Reserves
- 2023
-
Ingår i: Göteborgs Botaniska Trädgård, GIBCA Extended, 2023-08-19.
-
Konstnärligt arbete (övrigt vetenskapligt/konstnärligt)abstract
- The sculpture EP9 Starlight Reserves was installed in Amerikadammen in Göteborgs Botaniska Trädgård and part of GIBCA Extended 2023. This work is situated in the expanded field of sculpture, where the negotiation with a specific situation plays a central role in material investigations of environmental and sustainability concerns. The shape and title of the sculpture derive from the container of old batteries, "Exposed Pallet 9," which the International Space Station launched into space in 2021 to circulate around the Earth for 2-4 years before entering the Earth's atmosphere and hopefully burn up. [1] Commercial interests, colonization, and tourism led by rich nations and private companies contribute to the increase of space debris. The main inquiry of this research project is how artistic work, through visualization in sculptural form, can draw attention to scientific observations and advocacy in establishing international environmental space law concerning space debris. By using recycled plastic from electronic scrap for the large-scale IRBAM printing of the sculpture, the work highlights the potential for sustainable and ephemeral materials in sculptural production to promote environmental awareness and question the validity of the standard requirement for "permanence" in public sculpture. 3D printing in collaboration with Samuel Johansson and Woodrow Wiest RISE – AM center in Mölndal, Sweden with in-kind funding. Supported by Göteborgs Stad Kultur och Göteborgs Botaniska Trädgård. [1] Mike Wall, “Space station tosses 2.9-ton hunk of space junk overboard.

Tidskriftsartikel (refereegranskat)abstract
- As the IAU heads towards its second century, many changes have simultaneously transformed Astronomy and the human condition world-wide. Amid the amazing recent discoveries of exoplanets, primeval galaxies, and gravitational radiation, the human condition on Earth has become blazingly interconnected, yet beset with ever-increasing problems of over-population, pollution, and never-ending wars. Fossil-fueled global climate change has begun to yield perilous consequences. And the displacement of people from war-torn nations has reached levels not seen since World War II. © International Astronomical Union 2020.

Mars - a target for teachers and science students
- 2020

Ingår i: Contribution to IAU 367S, Education and Heritage in the Era of Big Data in Astronomy, 8-12 December 2020..

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- A case study is here presented of an interdisciplinary course about Mars for teachers and science students. We aim to share the experience of creating an interdisciplinary approach with lecturers spanning physics, geology, radiation physics and philosophy. Issues in ethics, morality, rights and obligations, conflict management and human psychology as well as rocket orbits, fuel economy, radiation hazards and knowledge of the solar system have proven to be a valued and successful initiative for the further training of teachers and science students. The focus of the course is on planning for a journey with humans to the planet Mars. This provides a great opportunity to package complex societal problems in a physics context. The course is offered with a special sustainability content mark. Mankind has always had a strong and dependent relationship with the physical landscape. The land has given us food and shelter but also imposed challenges and disasters. Understanding the physical environment has been crucial for our survival and development. The same will be equally, or more important for Mars where life conditions are much more extreme. We highlight similarities and differences in the geologic processes that have shaped Earth and Mars. What conditions do the future explorers on Mars have to manage? We then enter the modern era and explore the dynamic Martian landscape of today. Also, by learning to read the landscape we may find locations of shelter such as vast systems of lava tubes, or locations of essential resources such as preserved glacial ice etc. A journey to Mars will cause substantially higher personal irradiation than obtained on Earth. The radiation part of the course lectures starts with defining the different radiation types and the biological effects these different types of radiation will cause. Then, the difference between the irradiation on Earth to the elevated irradiation in space and on Mars is described. Thereafter, it is discussed if this elevated radiation burden can cause acute biological effects, e.g. fatigue, vomiting and death, and late biological effects as cancer induction. Last, possible radiation protection strategies are described and discussed. The philosophy of space exploration consists of philosophical approaches to ethics, presently applied to the topic of Mars exploration and colonization, with environmental ethics (anthropocentric vs ecocentric) and value theory at its core. Four main uses of philosophy are distinguished: ethics, aesthetics, cognition and existentialism. Research has shown that visual representation is an important part for students to be able to create a deeper understanding of concepts as well as context about the material that is taught. Interdisciplinary and complex societal problems have also been shown to be important in science teaching. One way for the teacher to develop his/her teaching is to take further education courses in universities whose focus is to seek and discuss the complex societal problems as well as its solutions from a physics and teacher perspective. Future research could be done on the impact of this course on the education in different levels.

[Prussian] BLUESHIFT – Space Debris 2551
- 2022
-
Ingår i: Stora Alvaret, Öland, Sweden, The Swedish Sculptors´ Association, 2022-06-11.
-
Konstnärligt arbete (övrigt vetenskapligt/konstnärligt)abstract
- The sculpture [Prussian] BLUESHIFT - Space Debris 2551 takes its shape from the satellite Cosmos 2551. One of the biggest fragmentation events in space took place in 2009 when the abandoned satellite Cosmos 2251 and Iridium 33 collided, leading to the destruction of both satellites. To this day, over 1000 catalogued space debris objects from the collision circulate around the Earth and one of the orbits passes right over Öland. When an object in space moves towards us, the light from the object is called blueshift, which describes the change in the frequency of a light wave. The color of the sculpture is Prussian blue, which is on the World Health Organisation's list of essential medicines and is used as an antidote to certain heavy metals and radioactivity. The artistic research work questions ownership and responsibility for the pollution caused by colonisation and space tourism. Led by wealthy nations and private companies, this reflects the colonisation of the Earth whose negative impact on the environment and cultures we have yet to come to terms with. The sculpture is mostly created from recycled material from discarded student projects from the HDK-Valand art school and the Gothenburg Opera's metal textiles set design from the climate-smart production of The Ring of the Nibelung.

Integrating and increasing awareness of the impact of artificial satellites and space debris on our night sky in astronomy education and outreach.
- 2023
-
Ingår i: IAUS385 Symposium on Astronomy and Satellite Constellations: Pathways Forward.
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- One purpose of this paper is to share experience from astronomy education and outreach at the University of Gothenburg where concerns about artificial changes to our night sky are addressed today. For the moment the following courses include topics related to an altering appearance of the night sky: •The history of navigation •Ethnoastronomy •Space Exploration •Interstellar Communication •Astronomy and art Another purpose of this paper is to seek information and ask for help. All the courses above could be further developed. In the future, home assignments will be included as a part of the examination. All ideas about relevant questions connected to the protection of the dark and quiet skies are appreciated. Suggestions of tasks for the students to aid in spreading information regarding the state of the night sky to the community are welcome. There is usually a large interest from both students and the media concerning risks of impacts of satellites on the Earth as well as the risk of collisions between artificial objects in space. Included is a discussion of the important factors to raise in outreach or education concerning impacts, as well as questions about ethics, risks, awareness, psychology, and possible connections to the global goals. Most likely, a larger number of strange looking or moving objects in the night sky, will lead to an increase in questions to astronomers about what people have seen. How should we answer, and is this an opportunity to inform?

”Sipping Cosmic Latte in the Milky Way, waiting for The Big Crunch” and ”We are taking great pains to make sure there’s not an orbital debris issue”
- 2022
-
Ingår i: Rovaniemi Finland, Arktikum Science Centre and Museum, 2022-12-02.

Konstnärligt arbete (övrigt vetenskapligt/konstnärligt)abstract
- The two sculptures in the exhibition encompasses, discarded materials from the Arktikum Science Centre, the HDK-Valand Academy of Art and Design workshops and the Gothenburg Opera. The sculpture ”We are taking great pains to make sure there’s not an orbital debris issue” includes images from her collaborations with the artificial intelligence bot Midjourney, based upon the Elon Musk statement which is also the title of the work [1] regarding the SpaceX expansion. In my artistic research practice I explore questions of ownership and responsibility for the (light) pollution caused by colonization, space tourism and commercial space tech companies. Led by wealthy nations and private companies, this reflects the colonization of the Earth whose negative impact on the environment and cultures we have yet to come to terms with. It is estimated that there is already more than 200 000 kg of artificial material on the Moon, and the number of large pieces of debris in space is about 20 000. The starry sky we look upon nowadays is actually scattered with artificial lights which impossible for the bare eye to tell the difference. The sculpture ”Sipping Cosmic Latte in the Milky Way, waiting for The Big Crunch” is a reference to the color of the Universe as defined by scientists Karl Glazebrook and Ivan Baldry, named Cosmic Latte for its creamy yellowish white hue. The Big Crunch is a hypothetical scenario for the ultimate fate of the universe, in which the expansion of the universe eventually reverses and the universe recollapses.
