An analysis of the current developments and scenarios for the transition to a fossil-free energy society this century

This century, greenhouse gas emissions such as carbon dioxide, methane, and nitrogen oxides must be significantly reduced. Greenhouse gases absorb and emit infrared radiation that contributes to global warming, which can lead to irreversible negative consequences for humans and the environment. Greenhouse gases are caused by the burning of fossil fuels such as crude oil, coal, and natural gas, but livestock farming and agriculture are also to blame. In addition, deforestation contributes to more greenhouse gases. Of the natural greenhouse gases, water vapor is the main cause of the greenhouse effect, accounting for 90%. The remaining 10% is caused from high to low by carbon dioxide, methane, nitrogen oxides, chlorofluorocarbons, and ozone. In addition, there are industrial greenhouse gases such as fluorinated hydrocarbons, sulphur hexafluoride, and nitrogen trifluoride that contribute to the greenhouse effect too. Greenhouse gases are a major cause of climate change, with far-reaching consequences for the welfare of humans and animals. In some regions, extreme weather events like rainfall are more common, while others are associated with more extreme heat waves and droughts. Sea level rise caused by melting ice and an increase in forest fires are undesirable effects of climate change. Countries in low-lying areas fear that sea level rise will force their populations to move to the higher-lying areas. Climate change is affecting the entire world. An estimated 30-40% o f the carbon dioxide released by the combustion of fossil fuels dissolves into the surface water, resulting in an increased concentration of hydrogen ions. This causes the seawater to become more acidic, resulting in a decreasing of carbonate ions. Carbonate ions are an important building block for forming and maintaining calcium carbonate structures of organisms such as oysters, mussels, sea urchins, shallow water corals, deep sea corals, and calcareous plankton.

Amateur Craft as Method-in-the-Making:

This research output documents a pandemic-era experiment in which academic researchers used knitting to record and reflect on their digital screen time, exploring craft as a critical research method and a tool for data sensitisation, feminist activism, and embodied knowledge making. Project Overview: A group of academics and amateur knitters from Maastricht University and partner institutions met online during 2020–2021, using knitting to document their own screen time over a week of lockdown. Their creative outputs—a collection of individually knitted rectangles—were later assembled as a tactile "knitted book" to display in arts and crafts contexts, as well as academic contexts. The project linked technofeminist thinking, craftivism, and artistic research practices, aiming to make visible both quantitative and qualitative aspects of technology use during social isolation. Main Topics and Learning Objectives: • Explore how amateur craftwork (knitting) can act as a research method to sensitise and interpret personal data. • Engage with concepts from technofeminism and critical craft studies to understand the role of tactile, embodied methodologies. • Foster social connection, experimentation, and reflection on digital dependency during the COVID-19 lockdown. • Develop awareness of how materials, technique, and individual interpretation shape both method and outcome in collaborative research. Audience: This work suits students, educators, and researchers interested in qualitative and artistic research methods, feminist theory, science and technology studies (STS), and creative digital-literacy pedagogies. It models interdisciplinary practice and encourages engagement with data, methodology, and making as interconnected experiential processes. Authors and Licensing: Authors: Denise Petzold (first and corresponding author), Laura Barendregt, Ruth Benschop, Anna Harris, Laudy van den Heuvel, Bernike Pasveer, Veerle Spronck, Sally Wyatt, affiliated with Maastricht University, TU Delft, Zuyd University of Applied Sciences, and HKU University of Arts Utrecht. The text is suitable for publication in open educational repositories and supports open, collaborative engagement with academic craftwork. The pictures of the digitised version of the book were taken by Eric Bleize.

Structured Electronics Design: A Conceptual Approach to Amplifier Design, 3rd ed.

Many people consider analog electronic circuit design complex. This is because designers can achieve the desired performance of a circuit in many ways. Together, theoretical concepts, circuit topologies, electronic devices, their operating conditions, and the system's physical construction constitute an enormous design space in which it is easy to get lost. For this reason, analog electronics often is regarded as an art rather than a solid discipline. Structured Electronics Design: Defines a step-by-step hierarchically organized design process. Is based on solid principles from systems engineering, physics, signal processing, control theory, and network theory. Provides a solid foundation for circuit design education and automation. Has been developed at the TU Delft since the 1980s.

Maker Lab Assignment: Semi-structured_Experiments

Before the Maker Lab students begin the open inquiry phases, they first learn and practice some important skills, supported by small assignments. This assignment is a "structured", or "guided" inquiry, where students know ahead of time the result they should find, but have agency in their experimental design, within some prescribed limits. By assigning all teams different methods for addressing a single research question (currently: estimating the acceleration due to gravity), they are encouraged to reflect upon how experimental design and equipment limits the certainty of empirical findings. This assignment requires teams of four students (organized into two pairs, each performing the experiment separately, but analyzing data and reporting on conclusions together). In two weeks (wherein students' course workload is 10 hours per week), the teams must set up experiments, controlling sensors with self-programmed Arduinos, collect and analyze experimental data, and create a pre-recorded video presentation to be viewed in class and aimed at their peers, followed by a Q&A. Note: If you do not (yet) have Jupyter Notebook, you cannot fully utilize the .ipynb file. But the attached PDF will give an idea of its content and functionality. Note also: In order to interact with and fully utilize the Jupyter Notebook documents (including their hyperlinks and pointers to data and image files), it is helpful to save the entire collection locally in a way that preserves the original directory structure. This is easiest to accomplish by downloading all files at once via the JupyterPython-materials zip file and unpacking it (extracting the files) to your preferred local directory. This zip file of all Jupyter Notebook materials is located here: https://search.edusources.nl/materialen/d144774e-9705-489a-b3cd-28e3618f7324 Contents: partial experimental instructions (for students) in Jupyter Notebook: Semi-structured_Experiments.ipynb (and .pdf ) grading form for pre-recorded video presentation (both .docx and .pdf )

Maker Lab Lecture Slides and Lecture Announcements

This collection of the Maker Lab's Lecture Slides and Lecture Announcements (alongside the Lecture Notes and several Assignments files) detail the learning material and activities that prepare students for the open inquiry phases. Specifically, students learn about experimental design and uncertainty analysis, and learn and practice some important programming skills for controlling sensors and processing and analyzing data. For context of how these lectures fit into the course activities, please see the example course schedule (published as a sub-page of the main "Maker Lab: full course materials" page). The Lecture Slides are .PDF files of the Powerpoint slides, while the .TXT documents are pre- or post-lecture announcements posted to the course's digital learning environment. The course runs over 15 teaching weeks, with two 90 minute class sessions per week ("a" and "b"), which explains the naming system of these files, with names that begin with the week number and session letter. Note that many class sessions (especially after the open inquiry phases begin in session 5b) have no lectures or other materials because they are devoted to students' team presentations or individual meetings between teams and instructor. Additionally, lectures 1b and 2a include exercises and discussions using Arduino code files, with the file extensions .INO, which are also included here. NOTE: These uploads are not yet working. Please reach out if you're interested in the files. NOTE: Instructors interested in having the original powerpoint files of the Lecture Slides are encouraged to reach out to me via forrestbradbury ("AT") gmail.com .
