Sovereign data spaces

Data is the new gold, petrol or diamonds. In order to bring this message home to all people in the EU, the European summit on digital sovereignty had a small exhibition of projects that address these issues. City data spaces is such an initiative which has been running for quite some time now. In fact, from a city planner and data scientist perspective cities collect already huge amounts of data and can offer them to service providers, businesses and each and every one of us to organize our energy consumption, improve mobility patterns or any form of data or video streaming services. The amount of data captured and to be stored is growing rapidly. Just think of the Internet of things (IoT), maybe that’s only your wifi-connected coffee machine, oven or heating. Now add AI to this which allows the system to learn about your daily patterns to start the device in time for you to focus on other tasks. As we would like these data to stay confidential, the need for European digital sovereignty becomes sufficiently clear. It will take a huge effort to provide an adequate digital infrastructure for this “brave new world” and many people to work towards this objective. Train the trainers already, cause otherwise this is going to take ages before we can harvest the benefits in safe and sovereign manner.

Failure time

In mechanical as well as medical components it is interesting to know about the usually hidden failure time of a product. The failure time simply means probability the component will seize to function properly or altogether. Usually, this probability of failure increases with the duration and the intensity of use. We might know this from cars or heating systems, but airplanes and heart valves obey the aame basic statistical models. Programmed failure time is a nuisance, which works against all efforts of sustainability, Over-engineered products would work much longer than the actual use case. Locomotives with steam engines that still function well even today might serve as an example of the latter case. The issue becomes a bit more complex if we consider not only the product but each single component. Maximizing profits often leads to taking risks with failure times or failure rates over a fixed time (a more general term than the guaranteed lifetime of a product). This sounds rather abstract thinking, but in modern military equipment the consideration of failure time, self-destruction or destruction by enemy play an important role again. Failure time of military equipment has moved to the forefront of issues of equipment and is part of strategic planning, like it or not.

Minds alike

Great minds, think alike. In the „propositions on happiness“, the author Alain mentions as inspiration for his thought process: Aristotle (XLVII) via Marc Aurel (LXIII) to George Sand (LXVI). This is an interesting perspective and abbreviation of the history of ideas. The impact of stoicism in his thinking of happiness becomes evident. Although originally he was described by another person as a relentless optimist, he was happy to accept this summarizing label of his personality. In his writings, that also may work as recommendations he stresses the importance to “know yourself”. That’s not an easy to achieve objective, as self-deceit is all to common.
However, in desperate moments or just on a rainy day (both are entries from Alain), you will need to know how to console yourself. Friendships and knowing how to please others become virtues, which contribute to your own happiness.
Perhaps the best summary of the history of ideas with respect to happiness is his last sentence in the paragraph “victories” (LXXXVII): “Le bonheur est une récompense qui vient à ceux qui ne l’ont pas cherchée.” In my own translation: Happiness is a reward for those who did not search for it.

Reverse causality

Reverse causality is a beast, which empirically minded scientist fear almost like death. However, many processes we study are running not only in one direction. In most cases, causality is tested with, or assuming, a unidirectional model of causality in mind. But some processes have not only a set of multiple causes to take into consideration, but some processes might be reversible or run in a rather complex manner, which are difficult to quantify. Mind captioning is a technique in neuroscience, where easy language is used to describe an image perceived in a person’s mind. Such thinking aloud data is based on thousands of brain scans, where people watched videos or images (study link).
In my own journey into the working of my mind I play around with different directions of causality. Sometimes the text is the origin and the image follows in a selection of a telling illustrations, but occasionally the reverse causality is at work. The image is the starting point and gets the mental process going. It is a rather complex process which is not easy to approximate with the help of algorithmic thinking. Reverse causality has many surprises to offer. As scientists we have a hard time to come to grips with it. (Inspiration Link)

Foul-smelling dictatorship

The animal world is full of interesting strategies of how to turn over a foul-smelling ruler or dictatorship. The ant queen of “lasius orientalis” infiltrates a colony of “lavius flavus” to spray the incumbent queen with a foul-smelling substance which turns the worker ants against their own queen and eventually kills the queen. This is a rather intelligent strategy to trick the defense system of rival colonies and prepare a takeover of a whole colony to install your own reign.
This may constitute a stark warning for democracies just as much as a threat to persistent dictatorships. In the age of the not so social media there is a lot of foul-smells produced. Beware of the risks to democracy as open societies are much easier to infiltrate than closed societies or dictatorships. (Link)

EU Digital Sovereignty

If we try to search for digital solutions, we shall encounter a whole lot of American and Chinese products, but very few European companies that are able or willing to compete. Hardware mainly comes from China, software from the US, at least until AI was not working in the background. If we add Russian interference to destabilize our digital infrastructure to the scenario, we are not really fit for the challenges of the 21st century. The very definition of a country or political union is the affirmation and competence to assure its sovereignty, particularly in cases of territorial conflicts with neighboring countries. My health or mobility data are a rather private affair, however, our state governments in EU-Europe have done little to ensure our data integrity. Business is also at a loss, if they do not spend heavily on data security themselves, usually relying on external cooperation. 

The EU digital sovereignty summit took place in Berlin on the EUREF campus in 2025. It can only constitute a beginning for intensified cooperation in  this long overlooked policy area. It will be tough to catch up where production has been abandoned for decades.

Headless Saint Dionysius

Denis of Paris stands for the Saint Dionysius, who is reported to have walked after being decapitated as martyr for his christian beliefs by the Romans in the 3rd century, all the way from Paris to St Denis in the suburb of Paris. We do not only find such a statue at Notre Dame in Paris, but also a medieval version in the Bode museum in Berlin. The cathedral of St Denis in Paris became subsequently the place for the coronation and burial of many French kings. The last king who lost his head through the guillotines was Louis XVI. It took almost another 200 years to abolish capital punishment altogether in France. Robert Badinter devoted his career to fight for this appeacement within the nation.

Freedom of art

Some depictions or statues of the 16th century quite expressive and average expressions of their time. An angel who is playing the lute in a rather extroverted way is amongst the remarkable artifacts we can discover in the Berlin Bode Museum. The Angel playing the lute is an oeuvre by Hans Brüggemann from 1520 in Husum. The angel certainly performed holy music with interesting postures, which resemble more rock stars of the 20th century or youth performing an act of “air guitar”. Artists always tested the limits of the freedom of art and expression. (Image from Brüggemann Angel playing the lute, Bode museum Berlin, 1520)

Surrealism Networks

The research project on the networks of artists in the group of surrealism ranges from the male proponents Breton, Ernst, Magritte, Miró to female painters like Lenora Carrington and Dorothea Tanning. The collection of Ulla und Heiner Pietzsch, donated to the Neue Nationalgalerie in Berlin, excels not only in the depth and breadth of the collection of surrealism, but also in the way it contributes to our understanding of artistic movements and network dynamics. For those familiar with the theoretical and literary underpinnings of surrealism by André Breton, the collection allows to follow the traces of ideas into artworks. Interdependent inspiration in multiple ways becomes visible in this exceptional exhibition. The special concern and concept to honor provenance of the artworks makes the trajectories of each artwork explicit. Thereby, the geographic dimension, importance of collectors, galleries and personal relationships to gallerists become tangible. Additionally, the seizure of the 2WW heightened the need to have contacts to survive Nazi-terror. You find it all condensed into just one room at the Neue Nationalgalerie Berlin thanks also go to the Zentralarchiv to facilitate and participate in the research and documentation. (Image: Miró Collage, Berlin Neue Nationalgalerie 2025)

Memory design

The progress in the field of genetic editing and design is astonishing. The research group of Johannes Graeff tested the “behavioral consequences of epigenetically editing the Arc promoter within engram cells”. Plasticity is a key feature of memory formation and the experimental evidence shows that this plasticity can also be interrupted. Moreover, the scientists were able to demonstrate a reversibility of retention or un unlearning of manifestations in memory of mice. The bidirectional reversibility of memory expression has potentially therapeutic value for traumatized humans eventually. However, if memory becomes part of a design feature of human species, the risks involved are just as important as the potentials. In totalitarian political systems techniques of “memory design” might be able to adapt such influences on memory, which used to be called brainwashing. Ethics commissions could get ready already to define safeguarding of human memory.  (Image: The fountain of Bacchus, Museum of Paris, 18th century wine merchant entry)
