The role of medical doctors during the Nazi domination in Germany has been revisited by the professional organization of statutory medical doctors (Kassenärztliche Bundesvereinigung KBV) in collaboration with the Center for Research on Antisemitism (ZfA TU Berlin). The exhibition entitled „Systemic Disorder“ first shown in the main entrance hall in front of a conference room offers a thorough review of the role of medical doctors throughout the Nazi period. Politically undesirable physicians were rapidly banned from the profession and promotions given to NSDAP party members. The totalitarian approach transformed the whole apparatus of the medical profession into a politically streamlined organization ready to commit crimes like forced euthanasia or selecting „insane“ persons for special medical treatments in other institutions. Selection of forced laborers for firms or declaring them unfit for work, which in many cases sent those persons to concentration camps, was part of the streamlined medical doctors. It took decades after the „Wehrmachtsausstellung“ in Hamburg that another profession has done its homework. Great to know that this important exhibition, documentation and catalog is traveling now across Germany for at least a year. It is another milestone in coming to understand how presumably intelligent people were part of a highly efficient selection and killing machine during the Nazi domination in Germany.

Famous Neighbors
Sometimes people believe they can catch a bit of fame, if they live in a prominent neighborhood. Next to a famous person or the glamor surrounding such a place is inspiring. In Berlin the honor or fame is transmitted for example with the street names of composers. Everybody knows Johann Sebastian Bach and around Christmas time many of his compositions will be performed again. Directly next to Bach street we find Flotow street. It needs a bit of info about music and music history to identify the honor for Flotow to appear next to Bach. Well, Berlin you are „wunderbar“. You have made my day just on one of the first few days of the direct train connection between Paris and Berlin started. We grow together in small steps. 
Reconciliation
European history is a long history of atrocities committed against humanity. The Documentation Centre for Displacement, Expulsion, Reconciliation in Berlin (Image below) captures this history in a comprehensive manner. We are quickly overwhelmed by this weight of history and the implications this has for the understanding of the people on the globe. This relatively new learning centre has, beyond the memorable permanent and temporary exhibitions, a room of silence to recover from the hard work of remembrance, always in view of reconciliation.
The library allows personal search and research of migration documents and biographies. All centuries have their history of displacements, but the Nazi terror surpassed all prior records and forced millions into displacement or death. We are still working on this heritage and the enlightenment of how these atrocities could take place. Full consciousness of the terror and horror of the 30s and 40s is necessary to guard against the many attempts to falsify historical events or discard the sorrow of millions of people and their families.
Reconciliation remains a continuous challenge. A large part of diplomacy has to deal with reconciliation beyond concerns of daily affairs. It is not just a matter for head of states and days-off during a year. Stillness helps to deal with the challenge, especially if it is very difficult to find adequate words. 
Air Concept
Well yes, this is the latest fart in design and architecture. The Berlin International University of Applied Sciences composed an exhibition on “Air Architectures” which takes air seriously. The international group of 7th semester students took Air Architecture seriously and developed their ideas in the context of a curated exhibition. Nice semester project.
Air is a fundamental precondition for humans to (co-)exist. The biology of air (breathing) or the chemistry of air (fine particle matter) have been studied extensively. The physics of air flows in cities receive more attention as well in architecture. Interior design has yet a lot to contribute in the age of heat pumps and air conditioning.
Let’s think architecture from the perspective of air and air flow. Depending on our cultural background we might have very different associations with air. Indian or Chinese practices like yoga or Tai Chi teach us to take air more seriously than Western practices. Most architecture in cold countries of the northern hemisphere aim to keep air to the outside of buildings. Yet, the percentage of humidity of air is a serious concern of architecture as well. Air flow and quality then becomes a key issue of construction and architecture, somehow through the back door.
Maybe in approaching architecture we might think first of what is or has been the architect’s concept of air or aerodynamics. 100 years after the death of Gustave Eiffel and the Olympic Games in Paris, we still gain from thinking about air (not only air pollution) and its dynamics. Looking forward to the next generation of air architects.

Health data
2025 will be a crucial year for health data across the EU. Germany introduced the electronic patient card, which can store basic information to then access data in the health insurance cloud for medical doctors, hospitals and other related health services. Potentially this is a great step ahead as some tests do not have to be repeated if they had been completed recently before already.
In pseudomised form, research may draw samples from such databases to enhance our science based understanding of disease. The evaluation of public health interventions becomes easier and medium and long term efficiency of measures can be assessed in many instances.
The Belgian research using health data has met to discuss the potential and limitations to link health data to other data sources to allow more complete and more complex analyses of health and disease processes. Another extensive data source sits on our smartphone. Collection of steps walked, sleep patterns or heart beats give valuable insights into a person’s own contribution and care about personal health. Although data are frequently incomplete, researchers are used to estimate missing data on the basis of existing or comparable person’s data. The basis for improving health for all are quite promising, data handling and linking them will be a challenge to the competence of all stakeholders and everyone involved in better health. It will be stressful before it becomes a routine. 
String Quartets
There is a plural form of Quartet. Philip Glass has composed a piece for 3 string quartets. Thanks to the Kronos Quartet performing and celebrating in Brussels, modern compositions are continuously added to the repertoire written for and performed by string quartets. Contrary to received wisdom the tradition of string quartets is still alive and kicking. At Bozar (Brussels) the marathon performance of 27 quartets, not all at once, but spread over a day and several locations, afforded a great free-of-charge opportunity to wipe off the dust from the sometimes rather introverted form of string quartets. Despite the high share of young musicians who performed well at the occasion, the afternoon focused more on new compositions. Concerning the audience, however, there is still an older age bias in listeners, more the standard Bozar clientele so far.
The afternoon reminded me on listening CDs entitled: “I don’t like classic music, but this one I do”. Many people came for art exhibitions at Bozar, but then (re-)discovered on the sideline the atmosphere of chamber music at this occasion. Closing the age and social gap in classical music is quite a challenge. It is surely more like a marathon than just a few sprints here and there. The new format at Bozar in cooperation with the Kronos Fifty for the Future Marathon will sooner or later find extended audiences beyond the happy few this time. I would recommend listening to string quartet music more often until the “Transcranial direct current stimulation (tDCS)” will be the new hype. 
Sociolegal Circularity
At times legal systems feel like going round in circles. Legal procedures move from one stage to the next and they may get referred back to the previous instance to resolve a particular issue or restart the procedure. This has good reasons with the aim of “doing justice”. Sociolegal circularity, however, begins before the, right at the beginning and negotiation of legislation on which all legal systems are based in democracies, that is. Hence, the legal definition of waste, recycling as part of the circular economy and society is rather crucial.
Circularity is a complex sociolegal issue as the example of PFAS in plastics demonstrate. In economic theory the existence of externalities invites profit seeking of the kind like: “the sea in large part is owned by us all and there is no price attached to the (ab)use of it. Dumb PFAS into the sea, because the costs of cleaning up will be shared by all of us”. In order to limit the extent of this economic logic, we have to rely on sociolegal processes. The precise definition of property rights and liabilities beyond the PFAS issue have to be well-defined. It is an intergenerational topic as well, not only in view of deferred payments.
Parliaments have to be rather competent to look through all the complex issues of producing and recycling of materials to make sound provisions in law including future generations. Going round in circles in parliament is yet another element of necessary condition of circularity in a rather broad sense.
The air we breathe and the water we drink have become part of this “economic externality”, which is a very internal, inside of our body kind of sociolegal affair. Who is responsible for the bad air we breathe and the contaminated water we drink? Air and water have for a long time become marketable products. The more your local water is polluted, the more we are forced to buy water. The more the air in inner cities is filled with fine dust particles, the more medical doctors, hospitals and rehabilitation facilities we need to construct.
For GDP calculations these are win-win-win situations, although they make us all worse off. Society and politics are in charge to define and redefine (yes, circles again) the legal basis with a lot of precision and scientific detail. Sociolegal circularity is key. You just have to turn it in the right direction.

Socioeconomic Circularity
Some sectors of the economy receive a lot of attention, for example sectors selling fancy cars. Other sectors, like the ones regrouped under the name of circular economy, receive much less attention and show up little in headlines. In fact, the circular economy is a great example of this. There are thousands of waste and rubbish collection, sorting and recycling centers, several hundreds of waste-to-energy plants, composting sites across the European Union. Of course, there is also a European Federation of the sector (FEAD). On the last FEAD conference in Brussels 2024 it became clear that Europe is finally waking up to the challenge of recycling costly raw materials.
The narrative concerning the sector needs to change further: what used to be subsumed as costly nuisance is in fact a potential profit center for companies and society at large. We do no longer want to import lots of raw materials from countries with dubious social and environmental records as part of our supply chains for raw materials. Time to act. This, however, is a rather complex socioeconomic challenge of circularity. The price mechanisms are not fully functional in most Member States, let alone across the EU. Additionally, the social practice to recycle varies greatly between countries. Distributional issues matter as well. It is rather obvious that dumping waste from one region/country in another one has huge implications (nuclear waste), but if one country values waste more than another one, due to innovative recycling techniques, the matter takes a marketable turn. Regulation should carefully distinguish categories of materials as we do for hazardous materials in production, consumption and for health and safety purposes of employees.
Metal, battery, cement, plastic and wood recycling pose challenges, but also opportunities to improve the European material import/export balance sheets. However, first in the circle of circularity is the use of materials. There we are clear that “less is better”. Less input of raw materials, most of which we import in the EU, reduces our dependence on other countries. This is the tricky social question of circularity. Mainstreaming of more conscious use and reuse of resources is a huge social issue, which we tend to relegate to a task for the education system. The awareness that supposed waste is also a valuable resource is spreading and the growth of the sector a business and employment opportunity for many. Circularity is the new sexy sector of the 21st century.
What have you recycled today? and myself? Well, scientific online publications. Now think of ChatGPT and the AI gold mines of 2024. There is lots of value in recycling.

Book Annotation
For most people book annotations are considered a nuisance. However, most pupils or students mark their so-called textbooks, which contain many images nowadays anyway. A good mindmap, summary of text, highlighting or critical comments may be part of their day-to-day working with a book. Some editors facilitate this using broad margins and more space between lines. Working through a text can take multiple forms and books have allowed over centuries different kinds of their usage.
There is yet another underexplored usage of books. On printed volumes annotations of previous readers may serve as a guide to a script of places, thoughts or material of particular importance. I have always found annotated copies of other readers interesting in their own right. Reading an annotated copy felt like reading another person’s mind, thought or learning process.
A modern view of books as a tool of communication might extend this perspective to study annotations of several readers on the same copy. Just like we comment today in word processing on texts from collaborators or students. Books are a means of communicating with other people or machines (AI) usually with the aim of spreading ideas, content, horror or pleasure.
Therefore, I am always happy to find annotated versions of a book, especially of prominent authors. It sometimes feels like reading a “partition”, a transcript of music which contains the comments or fingering of the reader or the performing musician. The BNF has a lot of such special copies in its archives, usually found in the donations of persons or prominent authors and their families to the archives. This can be put together to make an interesting exhibition of the process of thinking and writing and of special treasures – annotated books.

Passing Disasters
We live in rather cynical times. Just like the practice to scroll through hundreds of newspaper pages or social media entries we pass over the reports of of disaster after the other. Whole industries live from the reporting of disasters in a sensational manner. As the speed of reporting via social and online media has increased over the last few years the time to reflect what are the reasons for the multiple disasters has moved backstage. On the forefront are journalists and life bloggers who gain from increased reach and with the duration of their reporting of disasters. These are the first round effects. Second in line are people proposing fast fixes of what seems to be the problem at first sight. A more thorough analytical approach has little chance against the overwhelming effects of disaster imagery. Before the necessary dara and analyses have been carried out by scientists the next disaster already dominates the headlines and images. Flooding and droughts come and go faster due to climate change, but the reactions just del with reporting and capturing of attention rather than analyses. Next follows the blame game. Rather than unity to deal with consequences responsibility gets pushed from one instance to the next. Another cynical twist is the rise in insurance premiums to be paid by all, because the reporting hypes have increased the cost of repairs for insurance companies and after all more people shall seek insurance and have a higher readiness to accept higher rates for disaster insurance. Maybe this is just another more recent chapter of Sloterdijk‘s „Kritik der zynischen Vernunft“, which we witness currently. The effect of passing disasters is often a feeling of helplessness or powerlessness although we need to do just the opposite. Get together and act together after adequate analyses of underlying mechanisms. (Image Aristite Maillol Brussels, MRBAB)
