The period of the enlightenment is a historically defined time period of the late 17th and the whole 18th century. Although often associated only with Europe as its origin, the American contributions and influences have been far-reaching as well, just thinking of the “Declaration of Independence“. This historical period is, however, most interesting through the unrivalled contribution and pivotal point to the history of ideas. The exhibition and catalogue on the “Aufklärung – Enlightenment” by the German Historical Museum in Berlin exposes many of the historical editions of books that “made the enlightenment”. Philosophical writings and readings (Immanuel Kant: Kritik der …) of the period (especially in German) are tough even for native speakers of German, unlike reading of French (e.g. Jean-Jacques Rousseau) or English (e.g. John Locke) contributions to the enlightenment. Maybe this is already one of the reasons why in France the revolutionary ideas were put into practice through population-wide political movements.
The historical period of the enlightenment came to a close in the early 19th century (1806 another pivotal year). The English or French terms of enlightenment or lumière maybe be interpreted in a way that other historical periods like the medieval ages were periods of darkness, even later periods again did not live up to the idealist prerogatives of the evolution of humanity. The German term “Aufkärung” has its etymological roots more in the action associated with “to enlighten”. This hints at the continuing process of the ideas of the enlightenment in modern terms the process of individualisation, tolerance and autonomy.
There many valuable short interviews shown in the exhibition and Jürgen Habermas contributed a short closing statement to the catalogue of the exhibition on the unfinished project of the “Aufklärung” inviting us to continue also with the “Kritik der Aufklärung”. After all the enlightenment did not save us from repeated events like “Apokalyses“.

Apocalypse Depicted
At the beginning of the 21st century we have a renewed interest in depictions of the Apocalypse. “L’Apocalisse di Giovanni” has been illustrated in various Christian monasteries and some traveled quite a bit. The version of the Apocalypse (Link) which was attributed to Cambrai is a copy of the older original version found in the City library of Trèves, which dates back to the year of about 825. A flemish version of the 16th century is to be found at the BNF in Paris. Throughout the centuries the “Apocalypsis”has been reworked. The version of Trèves has the “carolingish” depiction characteristized by a presentation of image on one page and text on another page. Nowadays we are used to futuristic images and have known even worse experiences of apocalyptic events (Nazi terror). Earth quakes or man-made climate change with heating of the planet, storms, draughts and floods testify for the renewed interest in the Apocalypse. Other man-made technological innovations like rockets. atomic bombs, chemical and biological weapons overshadow even the “natural” ones. The potential of AI to cause destruction is not fully assessed until today. Swarms of drones guided by AI might reach apocalyptic levels as well. We just remind ourselves of the bombing of walls of a water reservoir by Russia in Ukraine. The Apocalypse will remain the original example of a horror story and our strange fascination for such texts, images or movies is likely to stay.

Wall Membrane
Walls are meant to separate persons. In certain circumstances, however, they work more like a membrane, which allows for example sound to pass walls. We are sometimes surprised to find out that we might hear almost every word that is spoken in a neighboring apartment or home. Listening without seeing is in fact a perfect set up for a comedy to evolve around this theme. Unintentional listening might turn into noisy listening and 2 lives start to intermingle. This is predestined for a comedy to evolve as does the theatre play by Lilou Fogli “mur mure”. The turning tripartite scenario by Jérémie Lippmann makes the 2 rooms arrangement visible where listening and seeing both separated actors a delightful experience. Understanding without seeing is better than seeing without understanding. Misunderstandings are frequent with the focus on appearances of persons. It is somehow the opposite of what our social media platforms suggest with their focus on stylized images and AI-enhanced photo editing. Hearing maybe the better seeing. In that sense the theatre play is in the emancipating tradition of authors like Ibsen or Chekhov, emancipating us from the dominant and overwhelming presence of selfies and self promotion. 
Law and Legality
Some persons consider themselves to stand above the law or push all interpretations of regulations beyond usual understanding of it. Even after a person has been dealing with pharmaceuticals or drugs used also for doping purposes, the conviction of such a person may take several years if not decades. In France, Mr Bernard Sainz seems to be a good example of such a relentless case of practicing para-medical consultations to assist mainly cyclists in endeavors to win championships or professional status. Le Monde and Cash investigation have raised awareness of the public for such dubious practices. The “French Federation du cyclisme” and medical doctors association fight a continued legal battle against this persons exercising illegally such doping assistance.
With apparently 56 legal procedures in connection with this person, the legal system has to bear the majority of costs of such illegal practices. 
The reach of such dubious practices might be extended if the systems beyond doping, but for assisted euthanasia cannot be controlled effectively. Hence, the precursor cases of positive stimuli like doping pose similar challenges to the legal system as “negative stimuli” weakening persons as assistance to die. The end of a life course is not only a medical issue. Society-wide debates need to take place in order to organize a large consensus on the implications more liberal practices shall entail.

La défense Végétale
Greening a metal and concrete block and buildings is a big challenge. The logic of unrealistic growth and big business has left liabilities for future generations. More vegetation in inner cities is part of our responsibility towards future generations. Therefore, urban planning has started in Paris to get rid of concrete walls and floors. 
Eventually the district might have a more human touch which attracts citizens and new businesses and services. The adaptation of the infrastructure to facilitate mobility with bicycles and secured pedestrian paths has started but will take a lot of time before people adopt again these more healthy modes of transport. The big boulevards reserved for polluting transport is no longer adequate in combination with residential living spaces. 
It will take a change of a whole generation to accomplish such a fundamental change. The reduced demand for office space due to more employees choosing to work from home contributes to such a change as well. Many other cities go ahead with similar changes (Copenhagen, Berlin). In combination with the „All electric society“ there are fundamental changes at work which will make inner cities more attractive again. Ease of clean transportation and other infrastructure for urban lifestyles ensures that cities remain strong points of attraction. They keep pulling people from nearby and far away towards them, if we like it or not. 
La Défense reframed
- The whole new business area „La Défense“ was a huge investment project with international speculators highly motivated to reap the benefits of a business location just next to Paris, which at best would even feel a little bit like being „intra muros“. However, being at La Défense you see „L’Arc de triomphe“ only quite far away and you don’t really get the impression that you are in Paris. The high rising buildings around there originally gave god reasons for expensive office space. Few residents spaces made the area uncomfortable in the evenings after office hours. After 2025 most office spaces no longer are attractive for businesses and lack behind environmental standards of the 2020s. Many projects attempt to renovate the former office space into residential buildings with a considerable loss in the value of previous office space. For people working in the multiple shopping centers there this might be a feasible option if the rent is not excessively high. Students in transit through Paris might find this attractive as well. Families, however lack an adequate infrastructure as this area was built for an outdated business center and business model where families were believed to obstruct business efficiency. As the project developers have written off their investments over 25 years society can clean up the remaining space and repair. It will be another medium term project to re-create a convivial environment and community there as before the overriding device was make money there and run to a more human and diverse space.
Hands-on AI
The use of AI in translation and to streamline texts and preparation of communication has become a common experience. The applications in medical fields are less well known. Scans and checking of skin cancer could be a game changer for many who live far away from the next medical doctor. AI assisted brain surgery is another issue, but a very specialized application. The interface of AI and robotics might be another game changer as such applications where you train the robot with for example weight lifting and transportation charges can contribute to alleviate human skeletons. Handheld devices can guide the robot and data from sensors will complement the learning of the tasks through assistance from AI. Applications are manifold and we have not even seen the most promising ones. The application potential in warfare are particularly troublesome as humans do not necessarily enter into the concern of AI-assisted weaponry. In the social sphere trust is a crucial behavioral and ethical concern. These issues AI can only learn from us. Any attempts to do without human input and control is doomed to fail. We are not indispensable yet, we are simply turning more and more into responsible, supervisory roles.

More eCooking
Cooking powered by electricity rather than fossil fuels like gas is an efficient and smart solution. Through the daily cooking activities over the course of a year the savings due to eCooking add up quite a bit. Even compared to an ordinary electric stove the eCooking by induction technology saves almost an additional 10+ percentage of energy as you heat the pot or pan directly rather than an in-between metallic element, which stores heat even after you have switched it off already for a while. In private kitchens the induction option is straightforward. In professional settings the change to induction eCooking needs careful planning. The health aspect of no burnt gas emissions in the kitchen is, however, a strong argument in favor of eCooking as well.
If we apply this logic to low-income countries and cooking in schools or other institutions as well as companies, the environmental and economic benefits add up quickly. In rural areas where no electricity grid is available or stable enough, the decentralized provision of electricity through for example solar energy creates a cost-effective alternative. In urban areas with high levels of various kinds of pollution the “clean” alternative could make a considerable difference as well.
The eCooking evidence is another pillar of the “all electric society” of the 21st century.

Beyond ART
Is there anything beyond art? Well, maybe there is. ART in German language is an abbreviation of “Allgemeine RelativitätsTheorie”. In other words the General theory of relativity developed by Albert Einstein is in its shortest form a one line mathematical expression, but with lots of equations included in the general statement, which grew out of his much earlier special theory of relativity. The textbook by Michael Ruhrländer provides a step by step approach to get to grips with the mathematics involved to reach a better understanding of what “ART” is about. Take your time to digest it and brush up a lot of maths beyond your A-level maths.
The abbreviation ART suggests a lint to art in popular understanding. Indeed, it needs able artists to show insights of ART to more people than the restricted scientific circles. An understanding of a 4-dimensional system of time-space has some more accessible features than waves of gravitation and the many puzzles that can be solved through ART.
Decades later quantification has build upon ART and takes us further into fabulous world of mathematical and physical imagination as well as real world applications. 
Corruption Caught
In fraud or corruption it is primordial that the probability to be caught is very high to deter potential fraudulent activity. The new Trump administration has enacted as one of the first executive orders that the FCPA stops to take on new cases of suspected corruption as well as reconsider some of the running procedures. In the same vein, the Corporate Transparency Act (CTA) has been silenced so that American companies to not have to disclose ownership information that fall under the CTA until 2025-3-21 until a major reform will be published.
These policy shifts concern more than just US citizens. The competition between countries will be effected because as companies trading with the US which used US bank accounts were also liable under this legislation and subject to prosecution. The FCPA has been an important example for other countries to follow at least within the Member countries of the OECD. The shift in priorities of the Trump administration might open doors again to corruption which we believed were shut with lasting effect.
In conjunction with the rapid increase in military spending when the capacity for the production of military equipment is slow to increase might increase the risks of corruption talking hold again. Market economies build on fair competition, but less prosecution of corruption introduces a bias into negotiations which works against innovation and competitiveness. We have a hard time to understand any kind of logic in such economic and legal strategies.

Digital Visions
Urban planning has been digitalized for a long time. 3D modeling of places and buildings including their interiors are state of the art. As urbanization is also about investment, speculation and anticipation, digital imaging has entered the public spheres in form of cover up of building sites behind fences and in form of large digital prints for information, curiosity and advertising purposes. The inner cities are frequently an avantgarde and microcosm of societal developments. Some dream of full or total flexibility for office spaces (see image below), others experience the inner cities as the spotlight of inequality in society. The best paid executives are catered for by the worst paid delivery personnel. The photographers of the Landesarchiv Berlin, Grönboldt and Wunstorf, brought together a documentary exhibition entitled „Pixel aus Beton“, pixel made of concrete. 
With a bird‘s eye view they reveal past, present and future details of how Berlin is experienced and envisioned by investors, architects and people living through the seemingly endless construction going on in the city. The keywords list as part of the exhibition creates a link to scientific literature and to the TU Center for Metropolitan Studies. Photography and even more so digital photography offers a social science perspective to the digital images exhibited. Cities are data spinning areas and a formidable place for digital visuals and visions. 
Top 5 Things T5T
Dealing with Elon Musk is a must these days (WSJ 2025-2-26 A4).
So it happened that on his way to Mars, Musk met God the almighty on his way back to heaven. Musk asked, whether he could join the ride.
God, not amused, asked Musk about his T5T (top 5 things) he accomplished in his life. Musk questioned God‘s right to ask this question and said he would tell the other T about this. God gave him just another day to come up with a response.
So here we are: the T5T Elon Musk might put forward:
(1) I created a million fancy electric cars.
God: Well, but there were already too many tin boxes on 4 wheels on earth.
(2) I created rockets that propelled billionaires into space and back again.
God: Your carbon footprint has exceeded a million people of the poorest countries on earth.
(3) I created a network of satellites that facilitated communication.
God: Nobody spoke to me yet using it.
(4) I bought Twitter and transformed the platform to spread evangelism of various sorts.
God: This has become a hoax spreading more lies than truth.
(5) I reformed the public sector employees to share my beliefs or leave.
God: This will ruin a lot of services like USAID, which have assisted me for many years in my caring and charitable service.
With all these T5T of yours in mind I am not sure I should let you return to that planet earth. Maybe I‘ll find another assignment for you where you can cause less harm Elon. Maybe, try “Waiting for Godot“.

Wave and Particle
The history of ideas in physics has been evolving or revolving a lot around the wave-particle-duality. Even if the basic debate by now is about a century old, we still need to come to grips with this challenging notion that light is not just a beam and nice colors through a prism yielding a spectrum of frequencies, but it can emit material matter called photons that have a non-zero value(s) of energy.
Max Planck came up with the formula E = h × f, where h is the Planck constant, E the energy and f the frequency of the photon. The synthesis of Einstein’s light quanta and De Broglie’s matter waves became the foundation of quantum mechanics.
The exciting evolution of physical ideas results in the state of the “art” view that, for example, light can take both forms, wave and particle, at the same time. Quantum mechanics has become a thriving field in physics and is currently transforming the world of computing in the 21st century. The amounts of funds invested in the race of applications of quantum computing across the globe are “astronomic” and have become part of dual-use spending of research funding. Encryption of information or access codes are of growing importance for civil (banking, mobility, health info) or military purposes. The speed of quantum processors will allow cracking of codes much faster and therefore new dangers are looming in many fields. It is a rather competitive field, which has evolved a lot from the original wave and/or particle vision of the world (of physics).
For social scientists there are several examples of applications of the concepts of quantum mechanics to social and behavioral sciences (Link 1, Link 2). Hard to predict, whether the wave and/or particle view will dominate the social applications of elements of the history of ideas in physics. New concepts in science challenge our traditional science-based thinking about time, space and space-time with implications even for our understanding of causality and covariance.

Negative time
In 2025 an experimental setting has come up with a demonstration of negative time. This is a mind-blowing mental exercise to imagine the science fiction like framework to allow time to be negative as well.
This invites several epistemological questions as well. Can we imagine or live with a reversible concept of time? Maybe music has given us clues. In composition of music, we can easily play the notes of a basic theme just in reverse or mirrored order. Modern rhythms like in beat music as accompaniment by a drum use for example a rhythm like (use your hands or drum sticks!)
“left left right left /
right right left right”, (redo faster if you internalized the rhythm).
A reversal of the beat (its inversion) like replays of rhythms in reverse order seem to return the energy. This beat pattern is perceived as forward moving and is advancing in chronological time. It has fascinated a whole generation and spurred crazy movements to accompany the rhythm.
A simple tune might be played in reverse order as well. Just take a piano scale and play 1 2 3 1 fingers, and then 1 3 2 1 in a mirrored fashion (1231 1321). Even 1 2 3 1 as 3 2 1 3 gives an impression of inversion. Through this composition technique you get a bit of a feeling for the potential of a reversal of time or what negative time might feel like.
The innovation through quantification challenges our concepts of time more and more. The direction of time is subject of a fundamental revision. Theoretical concepts have predicted this for a long time.

Quantification
The most obvious association with quantification is the attempt to quantify in the sense of measurement of situations, locations or social phenomena. This has taken considerable steps with the availability of smartphones that measure and thereby quantify all sorts of wanted and unwanted information about us. The distances walked are among the easiest to quantify. There have been many accounts and discussions about this kind of quantification. The results have been a further push towards self-optimization assisted by a quantification of almost all aspects of life. That is daily business of social sciences.
Quantification has another well-defined meaning to it, which is in physics. The revolution of the early 20th century has been to deviate from classical physics which assumed continuous processes in time and continuous measurements to the new world of quantum physics, another kind of quantification. This allusion is due to the Alain Aspect’s inspiring book “Si Einstein avait su” (2025) and his efforts to make quantum physics understood to a broader public. For me one of the merits of the book is the reminder that experimental physics can contribute and resolve many epistemological questions.

Time Concepts
Tell me about your concept of time. How do you define time? Answers to this question are likely to depend on your upbringing, affinity to a specific scientific discipline or epistemological belief(s). Aristotle defines time to be subordinate to the more basic principle of change. To understand change we need the concept of time. Two points in time define time, intermediate points are possible, which might be interpreted as a precursor of infinitesimally short spells of time. To explain change, Aristotle refers to his concept of time. Other concepts of time build on the notion of succession of events or sequences of events.
Clocks going round in circles have been used to show the progression of time independent of events. Beams of atoms later allowed for more precision of time keeping. The prevalent concept of time still is dominated by the idea of time as an arrow, usually depicted in some diagram resemblance based on the Cartesian coordinate system, but usually starting at 0 or a particular point in time as diagrams in economics.
Following on from the old concept of change and time, we still claim for causality in most day-to-day experiences or for social processes the link to a chronological progression of time. In statistical analyses building on time-stamped occurrences we may use event history analyses or stochastic differential equations to analyze (social) change depending on one or several (earlier) factors. Even the theory of deterministic chaos, which is applied in weather forecasts for example, arises from the sequence of point of measurements.
Mainly since Isaac Newton we cherish the notion of a universal time, which helps us to coordinate different locations on our planet with reference to the Greenwich mean time. Other concepts of time make use of infinity of time and how to deal with this. Life before, or life after death, are human constructs trying to make time understandable or at least manageable for us beyond our own living time. Depictions of time in the arts, paintings or music opens up yet another vast space of thinking about, as well as, experiencing time. We did have and still do have a great time thinking about time. 
Blue Sky
In the period of romanticism the associations with a blue sky were very different from today. Getting out into the sun was a kind of privilege for the “leisure class”, of people who could afford to enjoy time outside for boating, walking or other pleasures. In our technology-driven 21st century the associations with Blue Sky are more like a technically enhanced view through for example “Windows” at the news and opinion platform or “Bluesky”.
Several scientific websites that report data on blue skies and air quality more generally across the world report indicators like ozone values O3, sun intensity, micro particles 2.5µm and 10µm, Nitrogen Dioxid NO2 to name the mostly quoted indicators. Hence, just enjoying the blue sky outside isn’t the same as it was before. People working outside in the sun or at times of a blue sky but with high air pollution levels are incurring severe medium-term health risks. The Ozon layers at very high altitudes protect our skin and eyes against high UV-radiation, but O3 on the ground is tough for eyes and lungs.
Technology has come with many blessings, but the negative effects on a global scale become also more evident. Getting used to a particular lifestyle, which produces lots of emissions of aggressive fine particles will make it more difficult to just simply enjoy a blue sky.
In consideration of all these background data with regional variations, we surely need an AI-system which we can ask for advice, whether we should go outside and enjoy the blue sky with or without respiratory mask.
Romanticism has led us all the way to Californication and dangerous enshittification of the air that surrounds us. Youth and the next generations will have very different associations with Blue Sky than we have the chance to, at least, have had. 
Greening Interiors
The greening of facades of houses is an old tradition in many western countries. The outside of a home then changes colors with seasons. The home for insects and birds feeding on them makes a small contribution to biodiversity as well. Greening interiors is a more rare instance. Of course flowers and plants can contribute a lot, but there is yet more scope to green entire walls inside your home or office.
Moss has advantages to add humidity to the air. You might like the acoustic effect as well in busy environments. Taking care of moss is not easy. Professional assistance (Link) or renting options might be a good option for office buildings. The wellness enhancing effects are also interesting for some people who susceptible to the calming effects of a more natural environment. It is a matter of care and respect for air quality that is reflected in the design using green interiors.
Circularity is another advantage of the materials. We can so a lot for biodiversity if we really wanted to even in urban spaces. Global warming will force us to think more and more, and sooner than later to make use of such innovative solutions. For the time being they remain a luxury option. For the wealthy, greening interiors is easy, it much less an option for restricted budgets and people who are obliged to focus on short-term survival. However, we have to get started with the greening of our planet again, any way. 
Mindmap Me
Tools like artificial intelligence allow all sorts of transformations and depictions. The photo editing tools are widespread and particularly popular among the young users. My own transformative exercises, latest with www.bairbe.me, have yielded interesting insights, well worth an intergenerational playmate. For the guys there is the www.yobrick.com version for brick gamers. 
The App “Canvas” allowed me to delve deeper into my own mind by giving instructions of how to create an image of the structure of the blog entries on this webpage. Of course, it is not (yet) a real AI-generated content map, but it is only a matter of time until such tools will exist. After all, this would be just an arranged and rearranged list of contents using the hyperlink structure of the texts as well.
For the time being, I derive my own structure of the blog entries by topics, categories and tags including the hyperlinks or internal referrals. Interlinkages are mostly stated explicitly. However, there are many implicit links, which are obvious to some, but not others. AI-systems could use occurrences of words, synonyms and antonyms . Colors in addition to bubble sizes and (in)direct lines may complement such mindmaps. This can help to reveal another, additional layer to connections between categories or tags. The Ai-generated image shown below was created with the APP Canvas as a first approximation and AI-augmented test version in form of abstract images).
Next steps on the way to understand human intelligence and, maybe, augment it with a next generation AI-system would use a colored-3D version of such a mindmap and use the chronological evolution of the blog posts in a kind of evolutionary animation. This should allow us to go beyond the usual psychological classification of fluid and crystallized intelligence. We might come to grips what it means to be “in a Paris state of mind” or when hallucinations become overwhelming.
Apocalyptic Collection
As long as humanity exists we had to deal with the experience of apocalyptic horrors. First, mankind could not make sense of natural disasters. Second, after we understood many of the disastrous events on earth and even most cosmological events, we proceeded to create our own apocalyptic disasters.
One thousand years of unimaginable suffering and destruction are the subject of a unique exhibition at the BNF entitled Apocalypse. The documents start with biblical representations of it and continues throughout the centuries. The artists‘ attempts to depict and characterize the Shoa is part of the exhibition. The atomic bomb is another issue of the 20th century. In the 21st century artists try to move beyond the different forms of the apocalypse. The collection of various kinds of dealing with apocalypses constitutes itself an apocalyptic experience. We still have to go a long way to come close to understanding what drives disasters and what the role of mankind is on this way to seemingly endless destruction. The apocalyptic experiences remind us to keep asking some fundamental questions. (Image: Exhibition Apocalypse at BNF Paris, Center Piece by Otobong Nkanga, Unearthed) 
United by travel
The economic rationale of profit maximization privileges the construction and management of profitable connections. For train transportation this has spurred over decades the construction of new train lines between metropolitan cities or regions. Whereas connections between Paris and Brussels are abundant and expensive from central stations those living somewhere in between the 2 cities, for example in Mons, have had little chance of access to reasonably priced and fast train connections. This neglect of the in between cities is slowly changing. Sufficiently fast and reasonably priced connections allow Europe to grow together also at the margins. Public transport as alternative to car traffic across borders for „in-between cities“ will bridge the gap between the ease of travel between metropolitan an more remote areas. There is economic growth to be reaped as connected infrastructures allow for economic as well as social mobility and joint development. This is the real European challenge ahead of us and not the numerous summits without tangible results for rural and urban populations beyond metropolitan regions. For regions spanning countries, some will be finally reunited by better public transport a kind of ecological unification. 
HTML Mindset
The hypertext markup language (HTML) allows us to navigate on the internet. No matter which Browser you use on your device, it interprets the HTML-text for you in a specific way. This means: HTML defines headings, normal text, placeholders for images, actionable buttons and referrals to more text, images, or videos. A good HTML enabled textbook for pupils, students or any lifelong learner, for example, will embed easily images, sound recordings or video demonstrations in the e-book. This additionally embedded content asks for a different mindset for content creators: the HTML mindset.
Just like in most learning environments, learners proceed with different speed and interests. HTML allows for additional options to dig deeper into a subject, return to a previous stage, lead on from where you left off before, jump to some other content or listen to a translated paragraph.
Due to the bringing together of content from different technical formats, the HTML mindset has an interdisciplinary touch to it. Blending text and image is our usual way to process information at most exhibitions. In Hypertexts we are “walking” along our own chosen track through the knowledge space or content archive. For web creators, therefore, it is common to use so-called “content management systems” to arrange structure and present content.
The learning of HTML is enhanced through many learning tools (w3schools.com). This helps you to get into the HTML mindset of content creation and a better grip on the interlinked world. (Image: extract of HTML code of this blog post on www.schoemann.org).
AI Images
The creation of images using any AI system is fast and easy. Many people have tested the systems and experimented with the more or less explicit prompting needed for LLMs to come up with several suggestions. Through the use of AI in the creation of images you are indirectly become your own curator of these creations as you choose among many suggestions of AI for the same prompt. The next step in the process of these artifacts it to assemble several ones and submit your selection of images to a gallery for an exhibition. If you have a coherent approach or a specifically interesting creative idea you might get selected in a competition to show your AI assisted images in a gallery with a reputation to exhibit photography. The Brussels Photo Festival (2025) presented the submissions to a call for AI images with a broad range of AI assisted imagery. The focus of this project was on „historical events and figures“. In situations where images are absent such a newly created imagery might be helpful in re-creating narratives about undocumented wars or conflicts. Speculative fiction about other historical options or „roads not taken “ have found their way into museums of history even. Decolonizing imagery is an interesting aspect to get a grip on another way to view historical evolutions. Projecting biological growth processes into the future with pervasive bio-engineering allows is to imagine potential future scenarios. As AI in biology, pharmacy and nutrition is only about to rake off, the AI artists play an interesting role of new avantgarde in the 21st century before we shall be submerged by AI images on all social media platforms. (Image taken at Hangar.art 2025) 
Hallucinations
In the 21st century hallucinations have become a daily experience. The origins of the word can be followed back at least to the Latin verb “alucinor”, best translated with “to hallucinate”. As a verb to can conjugate it, meaning that I can do it, you can do it, s/he can do it, and we may do it in groups. Roman emperors did it, American presidents do it and, of course, AI does it. Hence, it is a great subject to study.
In “Nature” 2025 we find ways to limit hallucinations of AI systems. The strategy consists mainly in repeated queries of the same type, but from different angles. It is a bit like cubism applied to informatics. On “github.com” we can follow the rankings of AI-models using LLMs based on the “hallucination-leaderboard” developed by Vectara. On “huggingface.com” you can test the Hughes Hallucination Evaluation Model. For example it is possible to run a test of your own small text documents (just like any blog entry on this webpage) and what the AI systems will do them in an attempt to summarize your ideas. According to the “hallucination-leaderboard” we are confronted with a 1.3%-4% hallucination rate of the top 25 LLMs as AI-systems. In text based systems the quantity of “errors” is a first indicator only. The seriousness of the omission, addition of wrong information or an erroneous judgment will be left to the reader or analyst to uncover.
There is now a lot to do to test various AI-systems on their “trustworthiness” in summarizing my own work. My very own daily hallucinations have become a large data base as a test case for the capacity of LLMs to make sense of them.
Based on the series of passed blog entries I shall test the capacity of AI to predict the n+1 blog entry. It would be great to know today what I am going to write about tomorrow etc. Thanks to AI I shall have (finally) a sort of intellectual life after death (not sure whether I should want this). Enough of hallucinations and on hallucinations for now, back to serious readings or fictionalized science. (Image: extract from Delphine Diallo, Kush, 2024 at Hangar Gallery Brussels). 
Electronics repaired
The all electric society will have a number of consequences. We need to think about durable electronics. Many electronic appliances get broken rather quickly even by normal usage. The task to repair the beloved electronic gadgets of your children or simple electronic household devices reveals the fallacy of the consumerist societies. “Use it and throw it away, if it is not working any more”. This is the standard mantra of our societies. In order to save resources, we have to reuse, repair and re-engineer a lot of electronic devices. So far, the engineering process consisted largely in finding ways to assemble fast and with inputs as cheap as possible. The task of designing products that are repair-friendly, circular and allow to disassemble the product easily is a bit counter-intuitive to the consumerist society. If your juicer lasts for years, you will be unlikely to buy another more fancy one or even a connected one very soon.
Repair-friendly design and assembling will be the next generation products of the all electric society. Plugs, interrupters, relays and electric engines of older devices will be valuable after the original use in a household product, which has seized to function. Many parts can be put to other use. Re-engineering with sustainability in mind has an important function also in the move towards gaining autonomy again. For the repair of electronic devices we shall focus more on fine motor skills of our hands again. The shortages of electronic components to build cars after the Covid-19 crises and the disruption of supply chains for other reasons provide a good lesson to advance faster in the direction of electronics repaired. 
Synthetic opioids
Across the globe there are many tough lessons to be learned about synthetic opioids. These psychoactive substances fall under special legislation and can only be used with medical prescriptions. The strength of these substances is usually compared to heroin and the risk of addiction to these substances is very high.
A recent paper in International Review of the Armed Forces Medical Services (2024) has highlighted also “the abuse of the synthetic opioid U-47700” at times of military conflict. The power of these drugs to suppress the feeling of pain is helpful for medical operations. The abuse, however, may consist in the use of the drug to “keep fighting whilst pain is suppressed”. Such use of synthetic opioids increases the risk for addition and the fatal consequences of overdoses. The reporting of such occurrences in a specialized medical journal is an important warning against the conscious and willingness to abuse the drugs for war purposes.
The finding reminds us of the abuse that was already widely spread during the Nazi led 2nd World War (“Der totale Rausch“). The addictive potential was experiences even after the war time in terms of active combat was over. The costs to society of such abuse as well as use of supply chains of provision of opioids during peace times remain a problem for many years after the war. After a war, the war on drug abuse continues. Fighting addiction is a lengthy and painful process. 
Defence Spending
As in research there are many dual use products, which can be part of defence spending. Robotics in production or rockets to launch satellites for telecommunication are such examples. Much less known to the public is the amount of military spending that goes into medical developments that benefit both the military as well as the civil population. Countries build a whole ecosystem round the provision of medical services for defence purposes , which consists not only of a sufficient number of qualified persons, but also companies that provide specialised products. Most of them have civil applications as well after minor adaptations.
Oxygen provision was a prominent example of a product that has civil and military uses in treatment of respiratory infections or contaminations. A mobile transportable operation table is another element of daily rescue services as well as potential use in situations of conflict, just like anesthesia machines. An increase in spending on such infrastructure and the necessary long-term training of persons operating and maintaining these medical applications take time and considerable financial resources.
The current debate in Europe and NATO neglects the considerable time delays in production and provision of the equipment. Research on “Skill Needs in OECD countries” has shown the substantial delays between sudden skill needs and the time to train high-skilled persons.
The International Review of the Armed forces Medical Services is a journal dedicated to publish up-to-date information on needs of medical products and persons trained to use them in special emergencies. The need to safe lives in extreme and dangerous conditions needs preparation of thousands of specialists. Of course we hope that such an incidence will not happen. The persons and material have an obvious potential to serve the civilian population in more peaceful times as well. The unfortunate “hog cycle” in skill provision is not a problem for dual use products or services.

Corridorisation Connectivity
In some cities, “I love Paris” (Jazz Song), we admire the “breath-taking” large corridors, right in the centre of the city. This has been the outcome of the urban planning in the 18th century. Haussmann designed large parts of Paris with huge corridors despite the medieval narrow streets in some of the arrondisements”. Ease of traffic, fewer riots and representative housing became the new mantra of urban planning and superb boulevards.
In the 21st century it is about time to question the notion and social process of corridorisation. This has been accomplished in a paper by Fatima Tassadq et al. (2025). Modern infrastructure like fibre-optic cables, energy or water networks are easiest to deploy in urban spaces with large corridors than the complex narrow inner cities with supposition of different kinds of network layers. The grand ideas of the 18th century should be questioned from time to time and some districts that have escaped the corridorisation might well have a particular charm about them, maybe just because they seem to escape the rational approach of making and structuring space by means of large corridors. Large corridors separate city districts and they are a major driving force of gentrification.
The rationality of corridors has some roots in maths or physics of complexity. A recent paper by Shanshan Wang et al. (2024) reports the surprising finding that the transport corridors in several cities across the globe allow for a 1.3 times the distance of transport networks compared to the so-called direct linear “bird’s flight line”. Hence, corridorisation is (has been) a rather pervasively applied model of urban planning.
Alternative approaches advocate in favor of the 15-minutes walking distance city. All amenities like shops, schools, maybe work and services should be reachable within a 15 minutes walk. This does include “walking corridors” that facilitate (social) connectivity in inner cities. Cyclists also claim their corridors or fast lanes across cities, which underlines the pertinence to take corridorisation seriously and apply the concept with care.
In any case, social connectivity is key. The big social media platforms operate similar to the traffic infrastructure in the 21st century and provide huge corridors to knowledge and people. We only realize this once a service (for example tiktok) or the internet altogether gets disconnected. We have moved from (social) categorisation to (social) corridorisation as technology and rationalisation have taken the upper hand to structure our (social) lives. 
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.

Indigenisation
In reading up on the « all electric society » it is useful to see what the international market has to offer in innovation of electronics, but also to understand the potential of mass production. In this little research the came across the „Electronics for you magazine“ (LINK) from India is a great source. Trends of miniaturization of electronics and power savings for consumer products as well as some high tech space and wave technologies receive systematic coverage.
The November issue 2024 (p. 63) used the term „ Indigenisation“ to refer to the process of a country’s own technological development to ensure independence from being cut off from advanced technologies. Producing in India for Indian use seems to be an answer to economic and technological risks. India‘s space exploration program builds on own supply for civil and probably military purposes as well. Indigenisation of production, therefore, is an adequate term for own indigenous production of specific advanced components.
Contrary to the trend of globalization, which dominated the 2nd half of the last century, „Indigenisation“ is likely to dominate numerous sectors of the economy in the coming years. Made in India is, of course, a brand. Small countries might find indigenisation more difficult to achieve. It needs to be checked, whether indigenisation or „self-reliance“ (Atmanirhbar Bharat) implies plural societies and identities to the same extent.
