I do not collect data of detailed webpage analytics. Therefore, I thought I do not know anything and do not want to know anything about webpage visits of this webpage. However, the most basic information of how many times the webpage is visited per months is given by the hosting service of the webpage. The previous jump beyond 20.000 visits/month had the implication to move the security level of the webpage for me and all visitors to a higher level. Additional information of how many seconds an “internaut” is staying on the webpage tells, maybe a little bit about the interest in the content or image of a specific entry. Reaching 84.000 visitors/month was a surprise that asks for an explanation. Apparently, the most visited page is the blog entry on “geo-politics”. The longest time people stayed on a page or blog entry is a recent entry on “nutrition policy”.
Other statistics show that people who visited an entry on “find trust”, trusted in the webpage to click on many other entries or pages on “www.schoemann.org”.
I do not collect data or statistics on where visitors go after a visit. The hosting service, however, measures the so-called “jump-off” rate. This indicates the importance of the webpage as spring board to jump to other pages on the internet. It is usually = 1, just showing that you left somewhere. For some pages this reaches higher levels according to the number of links you offer on a blog entry, for example. It gives an indication whether you manage to lead on readers to explore the topic further. This is a usual evaluation question of lectures and seminars given at universities.
Last but not least, even without collecting any “real data” about visitors, it is part of the minimum information your browser transmits is the “operating system” used for access. Your smartphone provides the information on IOS, Android, Linux, or Windows versions used. These technical purposes remind me that there are still vast amounts of users of what we believe are outdated operating systems. Windows 7 and Windows 10 are still heavily in use across the globe. The hype around the latest operating system and smartphone is most likely only a phenomenon of the rich and wealthy in the rich parts of the western world. This reminds me to include images, which are small in data size to allow fast downloads in all parts of the world. We should embrace this as an important topic of geo-political relevance. 
Nutrition Competence
Nutrition is a good example of how a long lasting disregard in education and learning systems has led to huge medical costs for individuals and societies nowadays. The obesity pandemic calls for urgent action and policy changes in the field of nutrition policies and learning goals for children and adults. Medical doctors have mostly discarded that it is also their responsibility to provide medical guidance on nutrition, as this is highly controversial at times and asks for behavioural changes of the patient. School teachers see little scope to act on the issue due to increasing demands in fields of literacy, numeracy, problem-solving, digital and communication skills. Hence, the hope is to fill the instruction and learning gaps with a hybrid approach of nurses taking on both roles and communicate with children as well as adults alike. This is a tough challenge for these persons, but hopes a high that they can make a significant improvement to the nutrition competences of individuals, pupils, their parents and specific target groups.
The starting point is to recognize that there is an issue with nutrition. The next to establish the best evidence and based on this to develop a curriculum for the nurses to be well-prepared for the challenge in the field. Even with the differentiation of different levels of competences, the learning has to be rather encompassing several related fields as well. Individual, behavioural as well as society-level factors like biology, technology, religious beliefs, economic and social factors determine nutritional choices and consumption. Just because there are so many factors to consider does not justify to keep nutrition out of school curricula for example. Nutrition is a fine example of a topic which links disciplines across a broad range. It is a tasty, at times spicy mixture of issues to learn and apply. The former is the beginning, the latter the real challenge which needs ample and repeated guidance or coaching.

Nutrition Policy
The evidence on nutrition policies has accumulated a series of policy recommendations based on the best available evidence. The German Institute of Human Nutrition has presented these results repeatedly not only to the scientific community, but also to the interested public at the Science Week or the Long Night of Science. Their leaflet on the tools to improve our human nutrition in market economies highlights “nutrition competence” as a key component of a broad strategy to improve our food and subsequently health. Nutrition goes beyond the biological ingredients of food to include basic understandings of human metabolism including the times and timing of meals. This competence has to be transmitted to preschoolers, pupils as well as adults to stem the waves of obesity (ARTE Docu). Learning how to manage your own nutrition is a crucial competence to strive and survive. In schools it can have substantial impacts on performance and inequality of opportunities as well.
The science-based policy recommendations propose to alter the structure of costs, for example via tax reductions, in favor of healthy food. Plain water should be substantially cheaper than sweet beverages or alcoholic drinks. Nuts and proteins from vegetables fall in the same category as plain water. It is in the longer term interest of all of us that schools, canteens at work places or homes for the elderly offer also healthy nutrition at least as a daily option. More sustainability in food production is last, but not least part of nutrition policies. A lot to chew on to improve nutrition.
Science Transparent
Every year there is only one special big event (Lange Nacht der Wissenschaften) to make science more transparent to the population at large. Mostly hidden behind impressive walls and buildings guarded by porters,
science is not as transparent for the large public as it would like to be. In general people are rather intimidated or feel quickly out of place if scientist start to “explain” in lengthy formats their topics, ideas, questions and intermediate solutions. Even if the distributed open science fair is running only from 5 p.m to midnight, there are lots of things to learn and look into.
The website lists 1500+ sessions, 230 are in English language. You have to be selective or spread your interest over several years. I chose to start with, maybe, the toughest choice the Weierstrass-Institute near the Naturkundemuseum. Several projects of applied mathematics and stochastic processes were exposed and explained in more or less transparent and/or understandable form to the audiences. The talk by Julian Kern “Why chance doesn’t happen by chance” had a nice interactive format with “Kahoot-quizzes” and gave a good introduction, why it is useful to understand, statistics and stochastic processes in fields from biology, physics to social phenomena. The White board replaced already the black board and chalk.
The open doors policy, at least one day per year, raises interests and awareness for topics few people would only think that they existed already. The volume “Mathematics and Society” (Wolfgang König ed. 2016) is something I shall follow up on eventually. There are lots of applications of mathematics to social phenomena (time seen from the perspective of generations for example, image below from talk), which we have a hard time to come to grips with without the aid of mathematicians. 
Violence Potential
The book (editor Sabrow 2023) and the exhibition “Gewalt gegen Weimar. Zerreißproben der frühen Republik 1918-1923” need a broad European audience. The violence, which in the medium term destroyed the newly founded democracy of the Weimar Republic in Germany, is linked to the immediate aftermath of the 1st world war. The relatively calm abolition of monarchy in Germany did in no way prevent the eruption of violence within the new democracy. Extreme forces prepared in organized ways (Organisation Consul) and some in open public discourses the potential for the use of violence. Armaments left over from war equipped the Freikorps Movements and the potential to use the weapons was present at all times in the aftermath of WW1 in Germany. The contributions to the volume provide a detailed account of these 5 crucial years when democracy was able to defend itself against all odds. The strategies to take control of the country were built on a violent rhetoric which prepared the ground to put violent talk into action later on. This spiral of violence is hard to de-escalate once started. However, democracies have to foster ways to calm the spirits in periods of high potential violence. Elections as well as the campaigns before are the arms of democratic change. They should be used as such to pave the way to compromise.
Composing Assisted
Before the existence of digital composition tools composers were assisted by “Kopisten”. These persons rewrote the original draft of a composition into a “proper” version of the original document. Musicology has a tough time to deal with deviations from the original. It needs to be clarified which is the final and authorized version. In some instances this is far from evident. Just as an example Robert Schumann made ample use of the assistance of Kopist Otto Hermann Klausnitz (cf Nr 6), sometimes for the preparation of the composition, the finalized versions or the explicit drafting of different voices. Klausnitz himself was a flautist in Leipzig (Gewandhausorchester) and a conductor in Duesseldorf. Overall the debate is still going on, whether the composer’s draft or in many instances the Kopist’s version of the composition (authorized or not) prevails. In the age of AI, which is highly influential in modern music, such questions will most likely be intrinsic to the process of composition as well. AI is influential in evening out rough edges. Anette Mueller (2010) has done a great job to make this work of “Kopisten” much more transparent and her concluding chapter is programmatically entitled “Komponist und Kopist- Aspekte einer produktiven Kooperation”. (Image Mueller, A 2010 p. 340).
Cannabis Alcohol
The use of cannabis and/or alcohol is yet another question where we are used to ask questions in the form of: either the or the other? Over generations we have gotten used to no longer ask for each do you or don’t you. With the controlled liberalization or legalization of cannabis in some Western European states the framing of the question is more like you do the one or the other, particularly for many younger persons.
Decriminalization of both drugs in small quantities is apparently reducing crimes link to drug use and drug dealing. On the other hand, the thresholds for doing drugs are lower than they used to be. In inner cities it is therefore no longer a surprise to find both kinds of drugs with addictive potential next to each other (see image below). We know that it is a slippery road from regular drug use to uncontrolled dependency and personal disaster. For cannabis a study published in the Lancet (Petrilli et al. 2022) added the importance of the potency of tetrahydrocannabinol to the estimate of risks. This is similar to the studies that differentiate the level of alcohol in drinks consumed. The higher the concentration, the higher the risks. A simple proportional relationship prevails in both drugs. The cumulative effects of consuming both together might have quite surprising non-linear effects.
The big issue is the risks of mental health related to these drugs. However, the causal direction is not easy to detect. Drugs induce mental health problems, but also mental health issues lead to drug abuse. This remains quite a puzzle for scientists to disentangle.
Additionally, the link to smoking and addiction to nicotine is a frequently observed corollary. Studying just one single source of health problems and addiction might be too restrictive to learn about the whole set of causal effects and casualties. For the time being we seem to jump from one field of attention to the next one ignoring the multiple interrelated factors at hand. 
Democracy Enemies
Discussions in the social sciences about the fate of democracy have a long tradition. With the results of participation rates in elections for the European Parliament in 2024 weeks need to take up the challenge again. The book by Bryn Rosenfeld “The Autocratic Middle Class …” stated already in 2020 that autocratic regimes tend tp buy off democratic intentions through providing lots of jobs in the public sector which promise stable living standards and pensions to regime conformity. If the public sector crowds out private sector jobs this creates a tendency to lock in the current political system of autocracy. The analysis, however, lacks the explanation of the micro level sociological mechanism that made the “color revolutions” plausible in many parts of the world. Even the recent success of a government change in Poland in favor of pro European Donald Tusk would have been impossible if the buying of the middle class through public sector jobs is the overriding mechanism to avoid democracy to win the upper hand. Withholding funds to make public sector expansion more difficult or risky in for the longer term stability of an autocratic regime might do the trick. Autocrats have many enemies not only externally. The enemies from inside the society have multiple options for opposition as well. The other perspective that there are many enemies of democracy to be found within the public sector is another known challenge to democracy. Low turnout in Elections is a warning signal that we have to take very seriously and continue to act upon. (Image: Neue Nationalgalerie Berlin 2024 Extreme tension, explation on Ewa Partum)
Broken Promises
In a library catalogue, the entry of « broken promises « returns more than 3000 times that the title has been used. « Promises kept » is almost as popular. A rapid inspection of titles reveals that the former titles suggest more factual analyses, whereas the latter is frequently used in the form of an imperative in combination with “should be kept”. The book by Fritz Bartel “The Triumph of Boken Promises …” (2022) demonstrates the importance of the concept of broken promises in the social sciences. The rivalry between socialism, capitalism and the rise of neoliberalism is strongly influenced by the way they handle the breaking of promises made to their respective societies. The promises of increasing wealth and wellbeing have been part of all political regimes. To keep these promises is a completely different story. Especially since the first and second oil crises and many other kinds of crises, it has become much harder to keep these promises. Working hours, retirement ages or minimum wages are all at risk to no longer live up to the promises made in earlier periods. This has put welfare states under pressure that millions of voters perceive politics as a “game” of broken promises. Socialist political regimes like Russia are ready to use physical violence to shut up people that remind leaders of these broken promises. In democracies the ballot box is often used to sanction governments that do not live up to expectations of previous promises. A lot is about public infrastructure which is failing people. Migration, education, social and labor reforms are on top of the political agenda if it comes down to broken promises. The elections of the European Parliament gave many a chance to express their discontent about various broken promises. Maybe democracy is better in providing forms of letting off steam early and protracted protests rather than the Russian way to suppress any critical analysis, let alone opposition movements. Just like the move from industrial production to services as production models, with AI we are likely to see similar problems and probably also broken promises. The challenge is huge and promises should be made with an eye of what promises could be kept.
EURO 2024
Before the EURO 2024, (European soccer championship) has even started, the host country Germany and the DFB- foundation for culture joined forces for a remarkable exhibition. In the “National Gallery of Contemporary Art” and next to the Berlin Hauptbahnhof a provocative video installation is mounted that uses the imagery of soccer (football) to portray the life and atmosphere associated with soccer. Injuries on the playing field, but even more so injuries caused by violent groups among the spectators create an emotionally charged representation before, during and after the match. The role of the umpire is central in the match and in the cultural project. Shattered dreams are part of the game for players as well as spectators. Visual impressions have contributed enormously to spectacular success of football on television. The masses of viewers has created a big business of television rights and merchandising products as well. The DFB Kulturstiftung undertakes great efforts to open up the discussion about soccer in a critical way through art projects. The entry into the installation resembles the entry of players through a tunnel into the huge stadium. The world of soccer has multiple links to physical and psychic violence. The installation “Winner” signed by Marianna Simnett challenges the media’s largely beautiful videos about the world of football. In the ocean of enthusiasm this exhibition is just a tiny grain of salt, adding spice to life.
AI Ghost Writer
Yes, with AI we have entered a new phase of the impact of IT. Beyond the general applications like ChatGPT there is a rapidly expanding market of AI applications with more specialized functions or capabilities. In the realm of scientific writing AI-Writer is an interesting example of the AI assisted production of scientific tests. After the specification of the topic you will receive several options to specify the content of the short paper you want to produce with AI-Writer. You may choose the headline, keywords, subtopics and the logical order of these subtopics depending on your audience. Alternatively, you leave all those decisions to the application and restrain yourself to fix the amount of words you would like the paper to have.
AI-Writer is a powerful ghost writer for much work even of advanced scientists. The quality of the paper needs to be checked by yourself, but the explicit list of references, from which AI-Writer derives its restatements of the content, is just next to it. Your ghost writer AI is likely to replace a number of persons that were previously involved to just produce literature reviews or large parts of textbooks sold to millions of students.
A much lesser known feature of such tools is the way it makes plagiarism much more transparent for the scientific communities and the public at large. These programs demonstrate the techniques of combining knowledge and the citation imperatives in a transparent, almost pedagogical way. This latter function will speed up scientific work like dissertation drafting, since the reading up and documentation of previous literature in a field is a time consuming early stage of academic degrees.
Email composition, rewording, plot generator or social media posts are additional nice-to-have features of the new AI-assistants. A lot of work that has been outsourced, for example, to lawyers, consultants or other technical professions, might equally be challenged. Ghost writers have been around for centuries. With AI for everybody, they will also be involved everywhere.
(Image screen shot of working with AI-Writer 2024-6) 
AI Citation
In science we love citations. The whole issue about plagiarism is about use and abuse of citations. It is a core competence of scientists to properly cite the work of other persons who dealt with the same or similar topic. There are lots of conventions or ways of how to cite mostly defined by professional academic groups. How do we cite texts that originate from an AI-system? We shall have to establish ways of how to do this properly rather than to ignore the spreading practice of its use.
For the time being, we test AI-systems that provide references in addition to the text and even direct clickable links to the original work they use. The AI-toolbox is called “scite”. Your assistant by scite will draft a short note on a topic (for example: Minkowski space, see trial below) for you and provide the linked citations for follow-up. At the price of about 15 €/months it is affordable for students and young researchers. The texts generated will then, in many instances, acquire “intellectual property and publishing rights” by persons.
The ways to follow back on citations of AI-produced texts seems a trustworthy step ahead. The authors of millions of papers cannot claim more than the original ownership of the text. The academic mantra “publish or perish” has been turned into “publish and perish”. AI-enabled citations might alleviate the pain only a little bit. The profession of even university professors shifts as reviewer of texts from students to texts of machines.
Forecasting floods
As floods as becoming more frequent and more severe forecasting of such events is crucial. The recent example in Bavaria (Germany) of the Danube river (2nd longest in Europe) has demonstrated the role of forecasting to spur adequate behavior of people living in areas at risk of flooding. With the weather forecast announcing lots of rain for a large area the forecasting of floods needs to follow closely these trends. It is not only a question of expectations, but an issue of adaptive expectations for people to adopt appropriate precautions. In retrospect the early forecasts turned out to be fairly accurate in terms of the peak of flooding to be expected in June 2024. The Bavarian “Hochwassernachrichtendienst” (no joke, one word) forecasted on the 2nd of June about 7.50 as the peak to be reached in 2 days in the city of Kelheim. This was beyond the usual 4 warning levels based on an escalation scale. The forecast was beyond the frequent flooding levels established in the last decades. People and emergency services would have to adapt their expectations accordingly. Renewing forecasts is essential to guide people and services in their efforts to deal with emergencies and repair damages as flood levels recede. Management of crises critically depends on forecasting even if they are obviously prone to error margins which should usually be reported as well just like in weather forecasts. Adaptive expectations are key in combination with forecasts to ensure survival.
Adaptive Expectations
In economics it is important to understand the concept of adaptive expectations. We all form expectations about prices and inflation, but there is more than just simple expectations. These expectations guide our behaviors in many domains. If we expect a drastic price change for goods and/or services we shall most likely modify our behavior in response. We might want to advance a purchase to take advantage of currently lower prices in the expectation of higher costs later on. Most people would follow the price changes on a regular basis and adapt their expectations according to the updated information. It is an important process as there are millions of people who do this and this process drives price levels in many countries. In Europe we would like to see not only inflation, but also expectations about inflation to be around the target level of 2% per year. After the high price rises of energy and food (Putin’s war) as well as the disrupted supply chains (Covid-19 crisis) we were unsure, whether we would have to adapt our expectations for the coming years. The credit crunch in the last few years forced people to adapt spending plans and expenditures. We seem to have overcome these major crises due to rapid adaptive expectations. The crucial mechanism to achieve this is a timely and open communication of changes. Media have a role to play to not only spread the information, but to explain underlying reasons. This contributes to a widespread understanding of basic economic principles that helps countries to navigate stormy weather. It is like players of chess who adapt their strategy after the other player has acted or not according to their expectations. It’s simple, isn‘t it?
Co-authorship Kafka
In science Co-authorship is a tricky issue. Therefore, many higher reputation journals list precisely who has contributed what to the paper. In the teaching and supervision of bachelor, master or doctoral dissertations it is imperative to scrutinize the original contributions of authors to the subject. There are huge differences between universities to the amount of innovation or originality that is required to award degrees or the publication of the research and results. Rüdiger Safranski published with Hanser 2024 an essay on Kafka which has 224 pages, but a 16 page long list of the sources of the copy-paste citations used from the orignal Kafka writings. By scientific co-authorship practice Kafka should claim co-authorship of the book and the costs of the „Process“ should be paid by the publishing house. However, I enjoyed the many links between comments and the originals next to each other. It is like a data analysis that sticks plausibly to the original data. AI still has a hard time to rival with these skills, although AI is catching up faster than many of us might believe or want to believe. From a social science perspective we might say the original work of maybe only 180 pages is inflated to make for a longer text of 240 pages. This justifies, probably, the publisher’s price (€26) and the marketing costs. On the other hand it becomes evident that Kafka has an enormous impact on writers and seems to take possession of them in an encompassing fashion. You move with him, but rarely beyond him. Tough lessons indeed from the publishing world.
Portable Grundgesetz
Celebrating democracy in Germany is rare. We take it for granted that democracy persists, as most of us have not experienced it otherwise in Germany. This is grossly mistaken as the opinion polls show repeatedly in recent years. Therefore, it is welcome to find the “Portable Grundgesetz” at the “Demokratiefest” in Berlin and Bonn at the event to celebrate 75 years of democracy in West Germany and 35 years in East Germany.
The century-old tradition to produce miniature books has been revived and the miniature books have been widely distributed at the event. A side effect consists in the eco-friendliness of this version, which saves a lot of paper. It is fun also fun to turn pages rapidly and discover some paragraphs which we would not have read otherwise. “Daumenkino” is the German word for versions that contain many images. Maybe next time, an illustrated and/or animated version of the Grundgesetz could encourage youth to celebrate using the texts, §s and images to discover the fundamentals of our constitution.
325 years ago, Weigel the Elder has illustrated, edited and published such a tiny edition of the Bible. It is currently exposed in the treasure museum at the “Kulturwerk” in the “Stabi Ost” in Berlin. “Back to the Future”, lots of ideas we get by taking archives seriously. By chance inspiration is undervalued. Search algorithms have a hard time to replace this in an effective way so far.
Democracy celebrates
With all the bad experiences of Nazi-Germany and the failure to defend democracy in Germany against its fascist enemies in the 1930s, it was a pleasure to celebrate democracy in Germany together with a huge crowd. 3 days of information and party around the major institutions of democracy Parliament, government, federal governments, constitutional court and all ministries joining in with pavilions in the parks nearby allowed a bottom up feeling of democracy. Visiting the chancellery as well as the parliament in a single day shows the openness of these institutions and the ease of access to our political system. People of all ages and all walks of life strolled around and enjoyed the day. Freedom to voice your opinion was easy and many took their time to do it. Civil society organizations were a natural part of the show. We seem prepared to stand up for our democratic values and principles. This will be tested in all the forthcoming elections.
Image History
The archives of the history of movies and/or television show to us the multiple ways how images capture our attention and memories. Visual narratives are an own category of our personal and collective memory. The wide range of visual experiences are a powerful way to influence. Not only the movies and stories matter, but the whole range of images associated with the cinema world. Poster collections, newspapers and today the so-called social media multiply the original images. The Deutsche Kinemathek allows a special, critical understanding of image history as Germany has been using and abusing images and movies in a very manipulating manner historically. The message is: do not take images for face value. The ways and techniques to manipulate images have been widely used and are all around us today. Whereas the mass media in previous decades have dominated the collective memories we have entered into an era with many more subcultures that evolve within their own bubble of images. An original attempt to cut 65 movies of German film history into less than 4 minutes is presented in the exhibition (Milkowski and Simbeni). It focuses on gestures and “les regards”, “Blicke”, how the actresses and actors seem to look at us. Eyes capture attention, and this as soon as we open our eyes as children. Our brain works as image recorder and our memory algorithms tend to favor image recognition while processing images continuously. We do not know much about our own image sorting algorithm or algorithms yet. Research on aging of the brain gives some hints. With declining short term memory the images stored in long term memory take the upper hand. This makes an understanding of the history of images even more important.
Deutsche Kinemathek
Just in the vicinity of the Potsdamer Platz in Berlin you’ll find the Deutsche Kinemathek, the museum movies, actors, actresses, directors and the history of cinema in Germany. There is a small specialized library in the Kinemathek that allows to dive not only into journals and books, but also video material, scenarios and accessories. Of course, you will find a lot of material on all sorts of movie stars (heroines) over more than a hundred years. The “Divas” of the industry take up a large part of the exhibition. “Marlene Dietrich” much more than “Hildegard Knef“, the former born and the latter lived for a long time in Berlin-Schöneberg (Berlin-Pretty-Hill as some locals call it nowadays). The 2 Divas probably caused the funny translation. Anyway, the hall in the Kinemathek which is exclusively devoted to Marlene Dietrich impresses with a lot of glamour and mirrors around.
For those with not only a biographical, but also life course interest in cinema cherish the public access to the library. The most impressive table there is the desk with access to the Ukrainian movies and about cinema in Ukraine. A list with QR-codes allows you to readily approach the recent developments before and during the Russian aggression on Ukraine (See image below). After all Potsdamer Platz in Berlin was a hot-spot of the cold war period in the divided Berlin. A little bit of a “Metropolis-atmosphere” can still be felt. The Kinemathek explains well what this is all about. 
Camparing Covid-19
In the middle of May 2024 we tend to believe the Covid-19 pandemic is over. However, towards the beginning of the year 2024 in the U.S. we observed at the peak about 2500 deaths per week. 
In Germany deaths/week amounted to 250. Compared to the overall population size killing is more pervasive in the U.S. than in Germany. The map of the specialized agency “Centers for Disease Control and Prevention” (CDC) in the U.S. shows the coastal regions to be more affected than the center. Population density seems to be still a driver of the spread of infections, illness and deaths. The timeline of deaths due to Covid-19 infections for Germany follows a broadly similar pattern, albeit on a lower level even if roughly accounting for population size (RKI-data). As we tend to forget what the pandemic caused as social and economic disaster in societies, we have to stay alert as the major prevention of Covid-19. Learn to live with the virus around us. This means to keep up our preventive levels of hygiene as well as monitoring of trends.
Many thanks to all those who do the sometimes boring number crunching for us. This includes the medical doctors who bother to do the timely reporting of new infectious diseases on a regular basis.
Barbie Chemical
Chemistry is sometimes perceived to be uninteresting, but only until you realize it might be beneficial to know more about some underlying chemical processes. The Royal Society of Chemistry has finally found a topic in chemistry to give chemistry a popular push. The Barbie hype is far from over as we all learned in the recent past. Now conservationists have found a topic with chemical processes involved to demonstrate the usefulness of chemistry knowledge for the conservation of your treasures or collections of plastic dolls or puppets in general. Most plastics PVC was not intended to last, but the deteriorated forms have a long lasting effect in form of PVAS or microplastics. So aging research has reached popular concerns like the aging of Barbie, who is believed to be “forever young”.
Photos Exhibit
Our usual expectation of an exhibition of photography is to look at photos at a wall. Sometimes there is more it. The Exhibition Space at the “Haus am Kleistpark” features Michael Schäfer who attempts to go a bit beyond these traditional forms. In the works of photo cubes on water surfaces “2021_57”, or a dice floating on the waves of oceans, the video representation of his photographs takes the assembled images beyond their flat 2D surface. However, the 2D representation is at the origin, then transformed into a 3D dice, which then is animated as a 4D format. Moving beyond the flat screen image takes photography into the 21st century.
His work “Les acteurs 1-26” from 2007 is shown at the entry hall of the exhibition. It shows pupils of a class at an elite school who deem themselves in leadership roles in the near future. Is it acting? Is it projection into a future role they are likely to take on. They represent stereotypes, of course, but some are pretty convincing in these roles already. Some others still seem to reflect on what they are doing there. Even acting these roles, they are aware of the meaning of social rank and class in society. Without having read the sociologist Bourdieu, all are aware of the fine, little elements of distinction as they have evolved over time. We could teach an interesting sociology class in this exhibition. 
Science Politics
We tend to believe that science is independent of politics. Even if the individual scientist does research and studies free of immediate political influences, there are many ways in which politics has an impact on science. Sociologists refer to Max Weber as a prominent figure in the “Werturteilsstreit” that claimed the need for science to be conducted beyond political interference. Karl Popper is another reference in this respect who proposed the positive science approach which starts from theory, hypotheses and testing in the sense of identifying false statements, hypotheses and underlying theories. Modern science is also linked to publications of results. This has become an industry of its own and it is sometimes quite surprising to see the lengthy delays that scientific results get published. One example, Jackie G. Schneider and Julia Macdonald (2024) had to wait 3 years until their paper finally appeared in print in a scientific journal. This paper was received by the Journal in February 2021 and published only in 2024 in the 2nd issue of the journal but online in January 2023! Reports in Nature on difficulties of Indian, African and Chinese scientists to get their work done and published are alarming as well. Further regionalization and departmentalization work against the fundamental principles of independent science and scientists. It is a big issue of international cooperation as well.
Find Trust
Societies have different levels of trust. Trust in politicians or political institutions has been researched a lot. Another example of trust is related to things lost and found. Losing an item on a train or a mobile phone somewhere are severe tests of the level of trust in a society. How likely is it that the item is going to be found and returned to you. We usually estimate the probability of the return of items as being rather low. The more we are surprised to find out that there are thousands of items found and returned. The Deutsche Bahn has a special service in operation to take care of lost items. Additionally, there are auctions of items found but nobody claimed the ownership of it in the following months. Not giving up on a lost item is the first step to find it again. It would be a nice test whether in high trust societies it is more likely to find something lost. If you have a higher trust that items will be returned you are also more likely to make the effort to claim the item back.
Family Kafka
100 years after Franz Kafka’s death nearly all facets of his life and writings have been analyzed. The archives of the editor Wagenbach and the publishing house have now opened an exhibition at the “Stabi Ost” in Berlin adding a family picture book description of Kafka’s life (Curator Hans-Gerd Koch). This is of interest because Kafka himself had written an extensive letter to his father (Brief an den Vater) in which he tries to understand his intricate relationship with his father and other family members.
Nowadays, some people would try to analyze Kafka’s life through the parapsychological technique of family constellations. The far-reaching and pan-European family networks of the Kafka (father) and Löwy (mother) families were more than just an excellent source of inspiration. 2 younger brothers died in their first year. 3 younger sisters followed more traditional evolutionary patterns within families. The television series on Kafka’s life add to the understanding of his sources of inspiration and “parallel worlds” he created and lived in. The exceptional “fictionalization” of his own life and existence in the spirit of André Breton’s surrealism remains a milestone in the history of literature.
Kafka himself thought he was not really “instagrammable”at the time, but his image has reached and still reaches millions of people (Link to Picture archive). He himself would probably have defended the thesis that the most powerful images are within us. … and they are hard to escape from.

Hannover Fair
The annual science fair at Hannover is a kind of a show of things to touch and of those things that come to the public market in the near future. Most of the annual hype is about potentials of production. Rationalization, using few resources or innovative solutions of digitization are high on the agenda. Create your digital twin, save energy, make production more safe or cyber secured.
Robotics is another reason to visit the fair. Some 7 years ago I had my Sputnik experience there. The robotics company KUKA had demonstrated live the that assembling a car from pre-manufactured components takes just 10 minutes for the robots. Shortly afterwards the whole company was bought by Chinese investors. Roughly 5 years later we are swamped by cars from China. It was not that difficult to predict this at that time. Okay, we need to focus on more value added production and take our workforces (not only) in Europe along on the way. Reclaiming well-paid, unionized jobs in manufacturing, as Joe Biden does, will not be an easy task. Robots and their programming is expensive, but skilled workers, too. Hence, the solution is likely to be robot-assisted manufacturing as a kind of hybrid solution for cost-effective production systems.
Following the proceedings of the 2024 fair we are astonished to realize that visiting the fair is still a rather “physical exercise” walking through the halls. After the Covid-19 shock we expected a lot more “online content”. Instead we keep referring to webpages and newletters rather than virtual visits and tours. The preparation of the visit in advance remains a laborious adventure. However, the in-person networking activities in the industry are largely advanced by ease of exchanging virtual business cards and the “FEMWORX” activities.
This year’s Sputnik moment at Hannover is probably most likely related to the pervasive applications of AI across all areas of the industry and along the whole supply chain. Repairing and recycling have become mainstream activities (www.festo.com). Robotics for learning purposes can also be found to get you started with automating boring household tasks (www.igus.eu).
Visiting Hannover in person still involves lengthy road travel or expensive public transport (DB with ICE). Autonomous driving and ride sharing solutions might be a worthwhile topic for next year’s fair. Last year I thought we would meet in the “metaverse fair” rather than in Hannover 2024. Be prepared for another Sputnik moment next year, maybe.

Transparent Publishing
New technology pushes transparency of publishing, journalism and science to new levels. Through the hyperlink structure of texts it is easy to link back to the sources of a text. What used to be long lists of references at the end of a text or in footnotes has become directly accessible through weblinks. Only paywalls may or may not restrict the fast and easy access to original sources. In writing online, this is a major additional feature of publishing in the last few years. Some online journals allow this for quite some time now, but there are lots of printed versions that stick to the read and be stuck approach of publishing.
In teaching I have been an advocate of “read the original sources” as the basic source of inspiration for authors. The transparency of the thought process and the evidence provided in whatever form should be traceable. In publishing this transparency allows to exclude the copying of thoughts or unreflected referencing.
However, the task to check for the validity of weblinks and the updating is an additional task. 500+ blog entries with an average number of 2 weblinks per blog entry makes this a job of its own. Testing of 1000 weblinks is something you need a software or plugin which alerts you to “broken links”. The maintenance of a webpage, therefore, increases substantially as the content increases. Reorganisations of webpages make the follow-up of links sometimes quite hard. Projects like the general archives of the web and webpages are very important to ensure the transparency of publishing in the short, medium and long run. The archives of today look more like machine rooms than the splendid archives or libraries of the past and present. 
AI Reader
In the middle of the hype around AI it is useful to take stock of the reflection and evolution of AI. In my own analyses and writings on AI it evident that a narrowing of focus has taken place. Whereas before 2022 the writing dealt more with digital technologies in general. The links to the literature on the social construction of technologies was obvious. Algorithms and AI was a part of the broader topic of society and technology.
This has changed. The public debate is focused on “everything AI now”. We look at technological developments largely through the lens of AI now. Hence, my focus of assessments of technology from a societal perspective follows this trend. In a collection of blog entries on AI we try to demonstrate the far reaching changes that have started to have an impact on us. In the last few months the all encompassing concern about AI’s effect on us needs full attention of social scientists, policy makers, companies and the public at large. We can no longer leave this topic to the software engineers alone. By the way, they themselves ask us to get involved and take the latest advances in AI more seriously.
As a “flipbook” the online reading is rather comfortable (Link to flipbook publisher MPL). The pdf or epub files of the blog entries allow to directly follow the links to sources in webpages or other publications (AI and Society 2p 2024-4-18). The cycles of analyses and comments have become faster. Traditional book writing suffers from time lags that risk to make pubications outdated rather quickly. Dynamic ebook writing might bridge the gap between time to reflect and speed to publish or inform the wider public. The first update as .pdf-file is available here: AI and Society(2).
AI Travel
Playing around with AI it is nice to test take fun examples. Image you want to plan a vacation, then the use of AI is ready to suggest to you a couple of things to do. Of course, AI is eager to propose travelling services like transport or accommodation to you where it is likely to earn some commissions. So far, the use of the “Vacation Planer of Microsoft’s BING Copilot” is free of charge. In entering the time period and a region as well as some basic activities you’ll receive suggestions with quotes on the sources (webpages of public services from tourist offices mostly). It seems like trustworthy sources and the suggestions of D-Day activities in Normandy is a positive surprise to me. These are popular activities which attract huge international crowds every year.
Thinking further on the potentials it becomes evident that travel suggestions will be biased to those paying for ranking higher on the algorithms selection criteria, which are not disclosed. Entering into the chat with the AI you and AI can target more precisely locations and also hotels etc. You are disclosing more of your own preferences in the easy-going chat and probably next time you will be surprised to be recommended the same activities at another location again.
So far, I have bought travel guides or literature about locations to prepare vacations. This is likely to change. I complement my traditional search or planning with the “surprises” from AI for travelling. I rediscovered, for example, the public service of tourist offices and their publications ahead of the travel rather than the leaflets at the local tourist office. In order to plan ahead there is value in the augmented search and compilation capacities of AI. Drafting a letter in foreign languages is also no problem for AI. The evaluation of the usefulness of AI, however, can only be answered after the vacation. Outdated info or databases have a huge potential to spoil the fun parts as well. 
Repair Building
All buildings need repairs from time to time. For most of them the basic structure is solid enough so that isolation or maintenance will do. However, 100 years old buildings that have lived through 2 wars might have deep rooted deficiencies that are not visible at first glance. This can be observed in Berlin near the city center in a popular neighborhood with many visitors in „Schöneberg“ sometimes translated as „pretty hill“. The building at the crossroads seems to have been renovated only a few years ago, but the static of the building is so unstable that the city council has decided to block the whole crossing for circulation due to the danger of an imminent collapse of the building. The neighborhood has mixed feelings. It is great that the danger has been identified in time and blocking the road reduces the nuisance of traffic in the surroundings full of restaurants and cafes. The cover up of the repairs and renovation at the building is shocking as there appears to be just paint over basic structural faults. Construction work has failed to detect and prevent the static risks. An inspectorate that acts promptly to avoid bigger disasters is a societal asset.
