In addition to the annually proclaimed “We shall never forget the concentration camps and the murder of 6.000.000 Jews”, we should add: “We shall not be silent”. Silence about a crime can be interpreted as the “latent” continuation of hatred. Silence might just be a pretended ignorance of the genocide and the holocaust. We have to keep very alert amidst the spreading falsification and numerous falsification attempts of historical facts surrounding the ideation about the Nazi-time and Nazi-terror from the 1930s onwards culminating in the Shoa and systematic mass killings of civilians and any actual and deemed opposition.
Particularly in Germany there is a renewed need to go beyond the “Stolperstein-Initiative” and continue also sometimes own personal research of family histories in order to understand the logic and power of perpetrators. Some spectacular legal cases like “Klaus Barbie” or “Rudolf Eichmann” or the Nuremberg trials became historic events, but the crimes of many Nazis during these times remained below the radar of wider public attention.
In view of many disrespectful utterances of some politicians and even some business men the old and new perpetrators of antisemitic propaganda and acts should have to face more fierce opposition. This needs the commitment of the silent and sometimes shamefully indifferent people across the world. (Image: list of concentration camps, sign in Berlin Schöneberg, Richard von Weizäcker Platz).
Ukraine Chanson
The Russian war in Ukraine is not limited to the military killings. From the earliest period in 2014 already Russia initiated a war on Ukraine culture and Ukrainian cultural heritage. Therefore, it is great to witness the efforts by Ukrainian musicians not only to retrieve their rich heritage for example in the field of chansons, but to develop traditional songs with new formats. Jazzy versions of children’s songs have been sung with an admirable soft voice by singer and composer Viktoria Leléka and her band.
Most people might think of children’s songs as an insignificant niche of music. The importance of singing songs for children and babies is a scientifically well documented finding. Early bonds are created and a sense of belonging and comfort, particularly during difficult times of life. Comforting music is also an intergenerational issue. Transmission of emotions and values across generations is the very fabric of societies. The recent album “Kolysanky” and the song “Ne Zhal” is a great reminder that it is the children that count not the, maybe, broken cradle.
During the war time with many absent fathers, chansons can bridge the emotional hardships. The movie “The Chorist” had demonstrated the power of children songs for children, their parents and all generations involved. Chansons have a much longer “half-time of life” than war.
From an unknown French composer the cradle song “Fais dodo Colin …” and Brahm’s Wiegenlied are classics many people in Europe will remember from their childhood and still transmit them today. Great news that Ukraine continues this tradition with new, innovative adaptations of their own lively cultural heritage.

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. 
Cheatflation
There are many ways to study inflation. You may start by looking through your collection of bills. Economists like to swear by the consumer price index or indices, if you are even more into inflation. In textbooks like “economics for dummies” we learn about rational behavior and price adjustment mechanisms through the “invisible hand” to find some sort of equilibrium.
Advanced economics courses will teach you about strategic behavior inspired by game theory and the effectiveness/ineffectiveness of cheating. For advanced economists it is, therefore, inevitable that “cheatflation” should be part of the economists’ vocabulary. Of course, a profit maximizing entrepreneur is likely to way the risk of being found out contributing to cheatflation against the potential gains.
How to cheatflate? Too easy. Any producer of a product can cheat by using, for example, other ingredients than those printed on the product label, usually cheaper ones. Instead of fruit juice (wine) you may just sell colored water with lots of sugar (ethanol) in it, but still label it fruit juice (wine) and get away with this, until a consumer protection group makes a fuzz about it. A more sophisticated way is to sell investments in ESG-rated funds, but then include dirty stocks without proper notification in the fund, which probably increases profits based on wrong labels.
There is a specific quality to cheatflation, which makes it different from shrinkflation or enshittification. The drive to “obtain unfair advantages” through cheating across a whole country or region makes cheatflation an economy-wide process and subverts general fairness rules as well as trust in a society.

Obesity Revised
The scientific paper on a revised definition of obesity was produced by the special Commission on Obesity. It appeared in The Lancet Diabetes & Endocrinology in 2025-1. The previously common practice by medical doctors was to classify person in the obesity category based mainly on the simple calculation of the body mass index (BMI = weight/height²). A BMI > 30 put persons into the obese category and stigma.
Since the Covid-19 society-wide testing experience, we are all familiar what it means if you get misclassified and have to live with the consequences (exclusion from work or events etc.). The simplifying and summarizing BMI calculation and classification has also produced many wrong classifications. For example, persons with a lot of muscles (just watch this at any fitness studio) will have a high weight relative to their body height², but they are likely to be more healthy than many other light weight, but seriously stressed persons.
In empirical test theory such cases are the so-called false positive cases, i.e. classified as obese, but not a medical problem at all. Medical doctors and health insurances should not finance special treatments for these persons, which foregoes treatment of other more needy persons.
With new expensive drugs on the market to treat obesity it is even more important to test with more precision the normal, pre-clinical and clinical status of obesity. Fatty tissue or muscles, that is the relevant question. Fatty tissue in muscles is the next level testing issue. 
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. 
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.

Science and Fiction
We associate with science and fiction the extrapolation of scientific trends into some futuristic settings. The most striking examples of science fiction in novels or video use some scientific findings (dinosaurs, genetic engineering) and project this knowledge into another fictional setting. The usual personal relationships follow rather predictable plots of romance, deception, violence or war.
The novel “Wellness” (Hill 2024) is also a kind of science fiction as it is based on social science evidence and builds its fictional plot firmly embedded into the social and psychological research. The attachment of references (and defending the print of those in translation) underlines the commitment to write a new type of “social science fiction”.
In this innovative style the scientific basis of psychology and sociology is then extrapolated into a fictional arrangement. Research on subjective well-being with the U-shaped form over the life course and the extrapolation of the placebo effect, which is instrumentalized for a business, derive from key topics in the social sciences. In fact, the novel and the background scientific literature in the bibliography could well figure in a social science course at university entry level. These readings constitute a 360-degree-view on personal development and social structures. Of course, social sciences move on and add new evidence on an almost daily basis, but the selection and arrangement of the characters create an innovative social science fiction, without some unrealistic technological extrapolation.
It strangely feels like we are already part of this social science fiction (compare “Klara and the sun” by Ishiguro) as politicians advocate and campaign with placebo topics in elections and project us into some more happy past or future.
The social science fiction of Nathan Hill resembles for me the great utopian novel by George Orwell “1984” published in 1948. A title “2032” instead of “Wellness” could have worked quite well, as the first edition of Nathan Hill’s social science fiction was published already in 2023.

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.
