In a bookstore which sells books in English or American language we find lots of biographies or autobiographies of politicians. As a politician you don’t even have to be out of politics when your biographical account or your own view is published, let alone be written. Publishers seem to hunt politicians who made headlines, no matter good or bad. Outside the EU you can always sell biographies at half price, if the volumes sit for too long on the precious shelves of bookstores. Most of the biographies are found in the history section of shops or libraries, however some show off in sections like politics (if not dead for too long) or in the business and management sections. Leadership is a big issue in the latter disciplines, but the psychological or sociological literature starts to meddle with the received wisdom of how single person leadership is in fact facilitated with the many great people around the sometimes outstanding single person. Maybe the focus on a single person is an easily understood and simplifying concept of leadership. In the case of Obama (2x) two single historical accounts complement the one person focus. In 2025 Michelle Obama skipped the funeral of Jimmy Carter where she would have had to sit next to Donald Trump (according to the Daily Telegraph and probably endure small talk). Politics appears to move in circles and politicians might find themselves encircled. 
Space Missions
As we realize that critical infrastructure on earth is not safe in times of military conflict, space missions have become an additional form of competition between countries, continents and alliances. India has accomplished in January 2025 the coupling of 2 space satellites. The level of technological knowledge to achieve the coupling and decoupling of satellites included among other competences the mastering of algorithms that control sensors and propulsion. Beyond the communication cables on earth, satellites can assure telecommunication services, if other networks are interrupted.
The Indian Space Research Organisation (ISPO) has announced the successful “space docking experiment” (SpaDeX) and joins the other 3 countries US., Russia and China as the 4th country to achieve this. The race in space and to space beyond earthly competition shifts attention also to the additional category of a race to technological innovation and applications of those. Since the war of Russia in Ukraine we know about the “dual use” factor (civil and military) of satellite technology. Satellite images of your own country are helpful in many respects ranging from weather forecasts, rain, draughts and habitat changes or population movements. Early warnings of flooding are surely important civil applications. Movements of military equipment by potential enemies are much needed early information, which increases warning time spans. With more satellites in space the good as well as the dangerous potential is expanding. Sovereignty in the 21st century certainly has a technological dimension. Therefore, the demonstration of satellite coupling in space accomplishes not only a dual use achievement, but also fulfils a triple use or ambition. The 3rd one is political. Hey, look we are also watching you, or might do so.

Drawing Drafts
The exhibition “Drafts – From Rubens to Khnopff” at the MRBAB offers an art historian’s view on the role of drafts in the creation of art across centuries. You will not be surprised to discover that drafts played and play a crucial role in creative works. With a restriction to drawings, paintings and sculptures, the exhibition highlights the “creative gesture” originating in a sketch of a detail of a body, a face, the body, compositions of forms or perspectives on space. In some instances, infrared reflectographic camera technology or similar techniques were used to reveal the so-called underdrawing of a painting to allow the comparison of a draft with the “finished” or “published” version as an oil painting. The time span across centuries allows to stress the importance of drafts and drawing rather than the spontaneous creation of a unique piece of art. The 20th and 21st century saw this process of creation challenges by several artists and performative versions of art. The basic creative process, however, remains an important pedagogical access to better understand art and its creation.
The curators of the exhibition Bücken and Maréchal (MRBAB) encourage visitors to use pencils and paper to try out the technique of pencilling or just to try to a sketch of something of interest. This certainly contributes to let the message and encouragement to create yourself sink in to the memories of visitors. All in all a very modern view on old and not so old masters.

Modular books
Online publishing offers much more flexible forms of publishing. Even traditional book formats can be organized in new ways. Instead of a fixed sequence of chapters, paragraphs or blog entries, the sequence becomes a matter of choice. Either in the author’s hand or in the hands of readers, the cruising through content allows very individual experiences of what still is the same content. Just as learning, which is ultimately an individualized process, the reading or scrolling through content creates singular experiences with the content. Several choices of more in depth reading should keep the reader interesting to dig further along the personal knowledge trajectory according to own prior interests.
The motivation of a person to read depends on the reader’s own interests and current situation or context. The “state of mind” constitutes the willingness to stop at certain pages or entries. The search function, keywords or tags allow to deviate from an author’s intended sequence of chapters. An online textbook has easy entry and exit points. They are not predetermined. The risk, however, is that the reader stops at a point without loose ends, somehow in expectation of a conclusion of a succinct summary. That’s probably the easiest job for any AI system, based on a series of entries.
However, the joy of the journey through knowledge gets lost through the use of AI as a short cut. Just like physical exercise rewards you with additional strength, mental exercise keeps us healthy.
Traditional predefined sequences – like books, e-books or flip-books are also available on this webpage either through the post archive or the continuously growing books, e-books or flip-books page. 
Enshittification
Don’t laugh. This is a very serious scientific term to describe the way social media function in the 21st century. The scientific reference goes back to 2025 and article in “Science” by Kai Kupferschmidt. Twitter, now eXit, like most other social media platforms uses algorithms that select posts for you from the millions of posts that are likely to induce a reaction from you, which prolongs your time on the platform. Additionally, eXit Twitter applies an algorithm that prioritizes accounts with already a huge followership, which makes these accounts even bigger. The result is an increasing inequality in attention to info, facts, fake news, but also revenue for the platform owners through more advertisements. As hate speech and fake news are commonly perceived as shit, many social media are happy to spread more shitty things on their platforms as this generates more money for the platform as well. In short, enshittification happens sooner or later to most platforms and we all suffer from this. As user of these platforms, it is hard to escape from this process, as most platforms tend to “convert” to enshittification at some later point in their life cycle, unlike babies who manage to quit this phase after a few months. A move to Bluesky might be indicated, but there is no guarantee that the same process will just happen again. Mastodon is another small twitter-like platform that like Bluesky offers a more open approach to its governing algorithms and a more controlled access in the registration process.
To avoid enshittification, we have to be ready to move away from one platform to another one, just like changing bank accounts or club memberships. Make sure to take most of your friends with you and there are already tools for this online as well. Enjoy the safe online life again on another platform or consume more of the traditional media like newspapers, radio or tv with proven quality.

Investment Disinvestment
Asume we live in a world of fixed amounts of investments. The option to invest in a new project or product will automatically reduce the amount of investment in another product. The investment decision, therefore, is subject to opportunity costs. A recent study by Naci et al. (2025) applies this rationale to the investment in new drugs compared to financing other traditional treatments. The results for the U.K between 2000 and 2020 revealed that the „quality-adjusted life-years (QALYs)“ is not in favor of the investment in new drugs. The relatively small numbers of beneficiaries of the new drugs is compared to the many other persons who could have benefited from the less costly previous treatment. Investment in one new drug causes disinvestment in other ones. The overall balance for the UK turned out to be negative. Particularly the disinvestment in prevention of diseases appears to have very detrimental effects in view of the results based on this study. Preventative measures are relatively cheap compared to the estimated 20.000 pounds for one additional quality adjusted year of life for a new drug. The message is: choose your health investments wisely to avoid ever rising health costs and health insurance. (Image: rest room Belgium) 
EU Georgia
It is a moving image to see a hundred demonstrators at „Unter den Linden“ in Berlin just next to the Russian Embassy. The Georgian flag and Georgian people actively seek the association with the European Union and the values it stands for. Irrespective of a large majority of the people of Georgia‘s wish to become part of the EU they have to fight hard to be heard. Next to the Ukranian protests in Berlin it becomes very evident that these two nations fight for living standards and values which are so „self-evident“ for us European citizens that it is all to easy to forget about our neighbors who have to endure hardships with uncertain outcomes. The experience of having lived together under one roof with people from other countries allows to realize that we have so much more in common than what separates us. Our house and home of the EU has much to offer, more than we tend to believe in our daily routine. 
Career Criminals
From a life course perspective it is not easy to define a colloquial term like career criminal. A person who has been convicted for a single crime and has served his/her sentence should be allowed full integration into society. Even a repeated offender should not be stigmatized or labeled as career criminal. However, this is exactly what the NS-state did (traveling exhibition across Germany and Austria: „Die Verleugneten“). These persons were subject to targeted charges for criminal offenses they „might“ commit eventually. The term „community alien“ or „asocial“ were also used to refer to persons that did not fit into the dominant Nazi doctrine of „Volk“. It took 75 years until these persons could receive a recognition and a recompense for their unfounded discrimination and incarceration. In concentration camps the so-called asocial or career criminals were at the highest risk of further prosecution and death. Great that the stumbling Stones include these victims as well, as a way to remember these crimes against humanity. Beware of definitions of social groups which are based on totalitarian ideologies. 
Art Physics
Art is a matter of perspectives. In physics the change of perspectives and even theories about perspectives using optical instruments or illusions enlightens our understanding of the universe. 2D or 3D perspectives by V. Vasarely add yet another dimension through the oppositional hanging facing the Hollow Mirror Objects (convex and concave) by A. Luther (see images below). The curators succeeded in putting both art works with their incorporation of physical principles in an enriching dialogue. Art speaks to us in many languages. In more general terms, there is an underexploited aspect of exposing art. Rather than focusing on a single artist or school of artists in particular, exhibitions may focus on the interrelationships and new ways of combining or communicating images. This is human intelligence. Artificial intelligence will do this without prejudice and my own private collection of images of art works as a similar fountain of innovation as well.

Cumulative Mandates
Since 2010 and with 18 volumes the documentation of perpetrators assistants free riders during the Nazi rule in Germany has been valuable and reliable source of information (Kugelberg Verlag). The book series defines the perpetrators as the persons excuting crimes themselves or were in command of those who committed the crimes or gave orders to do so. It is not surprising to find evidence of many crimes, but rather that it took such a long time until the documents were published and the descendants were confronted with the facts and the difficult heritage. There are still many who undertake all efforts to deny the facts or try to minimize the guilt of perpetrators. With the real dangers of new right-wing extremism on the rise across Europe and even beyond, it becomes more important to uncover the strategies and biographies of the perpetrators. Certainly the members of the SS were executives and in command of atrocities, so-called NSDAP party officials were also mostly convinced followers of Nazi doctrines and instrumental in the implementation of crimes. Additionally, several professions (line soldiers or medical doctors) were key in the process to ensure the power of the totalitarian regime until the final days. Some persons were cumulating roles and became thereby inescapable spiders in a web of control and crimes. The lessons for today consist in hindering excessive cumulation of mandates, political, professional, military and in other work or civil society related functions. Distribution of power is one form to safeguard the survival of democratic structures.
