Defense strategies

Technological developments of drones, aircrafts, rockets and satellites take a lot of time. In order to produce not only prototypes, but ready-to-use weapons, it needs advanced engineering competencies and capacities as well. The arrival of hypersonic rockets, that fly at the speed of 5 Mach necessitate a rethinking of defense strategies to be able to react in ever shorter time spells to external threats. The European Defence Fund intends to spend almost 3 billion € over 7 years to prepare our defense strategies in the EU for the next generation of lethal weapons.
On 2026-3-4 the Iran-regime made use of such a fast rocket, but it was possible to intercept its flight just in time by NATO-allies. Yes, unfortunately “rocket science” is back on the research agenda. In fact, this research has been ongoing across the world, just a bit more below the public radar.
Missions to the moon or mars have been intensified in recent years. This is not surprising or spectacular fact. For some it is surprising, that the number of countries (for example India) which are active in rocket science is increasing and spreading further across the globe. The multipolarity of the international political arena seems more evident in 2026-3.

Construction Deconstruction

The application of dialectic thinking invites us to explore the idea of construction at the same time as destruction. The sequential form reminds us that on most construction, deconstruction will follow eventually. This is obvious in case of the life cycle of human bodies or the animal world. On a more aggregate level, empires have been constructed and sometimes centuries later, they have been deconstructed again. Deconstruction may also take form transformation. In such cases major features remain the same, but the new entity is sufficiently transformed to give it a new name. Often it might also be a kind of synthesis of previous generations or cycles of construction and deconstruction. We enter potentially into the field of genetic evolution or genetic engineering. In any case, dialectic thinking is present in many fields of studies. Well worth to explore the potentials as well as limitations of the basic scientific concept.

Book as Entry

Libraries are full of books. But there is much more to a library than just books. However, many users of libraries focus on the “classic” origin of libraries as large and more or less exquisite collections of books. Therefore, it is a decent tradition to think of libraries and most of all books as a kind of “memory of the world”. Judith Schalansky writes texts and conceives books. Authors are used to choose typescripts from a huge potential choice. Going through the history of book production, can inform about the diversity of appearances of texts in book form. The panel discussion at the Stabi West in the presence of Schalansky and about Schalansky raised awareness to the point that there can be many more than just one entry into a book. However, we are so used to read front to back, that it is even hard to think about more entries. Images, typescripts and typesetting or the kind of binding, all may serve as facilitators for more ways of handling a book.

Social time

What does the „social“ have to do with time. Well, time is a perfect case of a social construction or a fundamentally social construct. The definition of time as „Greenwich mean time“ is nothing but a useful socio-political statement to synchronize time across the world, or previously an imperium. Points in time, as shown on a clock(s), can be helpful to synchronize human behavior. We might want to show up on the same point in time to start or end work. Of course there are thousands of ways in which such synchronization might go awfully wrong. This makes for splendid drama and movies have a long history to capture our attention on this matter. Social expectations, a social, psychological, and even a biological concept in extreme cases (Pavlov effect) make many of us to get a bit itchy, if time is getting short to meet other persons or an expected event is going to happen. A lot of social pressure is transmitted through the ticking away of time. The mechanism to internalize social patterns (for example prayer), via time and the clock, is quite powerful and has been used in movies throughout the history of the cinema. Even the individual endpoint in time is in almost all cases a shared social experience and turns into a kind of socially relevant time. (Take your time to watch The Clock by Christian Marclay).

Metabolic harm

At the beginning of the 21st century the lack of physical activity for large parts of society has become a major risk of and cause of metabolic harm. We have become used to a sedentary lifestyle and the digital access to distractions and information have encouraged further immobility. Alex Broom et al. (2025) stress the importance to include social and governmental interventions into the many existing medical, pharmacological and technological interventions. The authors advocate a rather holistic approach to really make a difference. The obesity trends cause metabolic harm of an  unprecedented size. We have to rethink mobility patterns and other behavioral changes into our daily routines to bring back more stimulation to our metabolic system.

Good or bad

We have been taught by Shakespeare “to be or not to be, that is the question”. In political science we have pondered the question in a slightly augmented form. “to be good or bad, that is our question”. The basic image of women and men in society has been a subject throughout the history of ideas. For those who believe in the good nature of mankind, they tend to find reasons to believe that eventually mankind will find a way towards a peaceful cohabitation on our planet (there is no planet B yet for humans). On the other hand, each outbreak of violence and war are considered as a confirmation that mankind will always recur to some form of violence, even after extensive periods of peaceful cohabitation. According to the evidence presented by Meller, Michel, van Schaik, referring back to Kant, trade between people and nations is likely to prevent more violent relationships (p. 330). One of the major conclusions over the long term view of mankind is, that the periods of war have been far shorter and more rare than a focus on the last 3000 years seems to suggest. Maybe, “to be good or bad” is just a question of demographics of being too many at the same time in the same place.  Population growth and population density might be a powerful driver of “being good or bad”.  (Image: Delacroix, Last words of Marc Aurel)

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)

Dynamic Equilibrium

The notion of a dynamic equilibrium is applied in several scientific disciplines. The search of the world wide web takes us first to the application in chemistry. The dynamic equilibrium denotes the state when reactants and products are continuously converted. Fascinating as a process, there are videos where you can watch the process evolve. Applications in economic or social theory are also common even if the time scales to observe such processes of dynamic equilibrium usually take longer to evolve than in chemistry of bubbles. In physics we ponder about dynamic equilibria in Newton’s view of gravitational forces between planets and the celestial system. With a more down to earth approach we might just admire the dynamic equilibrium of an artist on a rope, before we dive into the complex challenges of the new balance of power in international politics of the multipolar world.

Deep reading

Rembrandt depicted in the 17th century not only the university professor Sylvius, but the reader and presenter based on his readings as well as professional experience. The combination of studies in medicine and philosophy have confronted the lifelong reader with lots of unresolved issues at that time. Nevertheless, he seems ready to argue with his profession, students public or the public. His hand is shown with an outreaching gesture. The scientist is not depicted in the reading pose next to lots of other books in the background or in a library. The image chosen by Rembrandt stresses the discourse and discussion as part of the scientific or research and teaching process. (Image BNF, 2025 exhibition “L’Europe partagé”).

Social Anthropology

Dina Dreyfus, married several years to Claude Lévi-Strauss, has shared with Claude the long anthropological expedition to Brazil in the 1930s. They jointly studied the social organization of indigenous people across Brazil. Their abundant notes of field studies have now been digitized and the BNF is making this accessible.
Additionally, an exhibition on these field studies reveals the close collaboration of both partners. Returning to France in 1939 meant that soon after the return due to their Jewish decent had to interrupt their academic careers in France and some notebooks were lost during the Nazi occupation of France. After the war both separated and Claude Lévi-Strauss embarked on the drafting of the structuralist theory, Dina became influential in the field of the philosophy of education and teaching philosophy herself.
Besides all these lasting achievements, the exhibition shows the typewriter which had accompanied them for many years. The German language layout is quite remarkable as this asked for an additional mental versatility in putting their thoughts and experiences into the form of a manuscript. According to Claude Lévi-Strauss the use of this technical device allowed him to detach himself emotionally from his analytical work.
