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.
May 1st
More people take to the streets on the 1st of May in Germany. The costs-of-living crisis with high inflation has increased the claims for pay rises for workers and adjusted wages for employees. We all have observed “greedflation”, i.e. excessive company profits in several sectors. Additionally, “shrinkflation” has affected consumers in their daily shopping experience. Political efforts to curb inflation have taken a long time to come about and most initiatives have ended already (Energy sector). This spurred a new drive for trade unions to come out in huge numbers to protest and claim adequate wage increases to cover the increased costs of living. In Germany the DGB informed on the annual 1st of May demonstrations across the country about a strong new entry movement of members of 400.000 persons. It is higher than the loss of members of the large baby boomer cohorts who retire.
Through a broad and engaged membership the pressure on higher wage settlements will persist. Companies have used the crises to generate extra profits. It is only fair that those employees who largely contribute to the success of a company will claim their share as well.
For society as a whole it is important to consider that the discrepancy between managerial pay and shop floor wages do not increase further. The social fabric of societies is in danger if perceived injustices grow. More radical forces can all to easily exploit this causing a severe danger for democracies. Meeting people on the 1st of May and joining forces across sectors and trades ensures that a society continues to build and rely on solidarity. High inflation times are a great reminder of the economic basics of societies in history as well as today. 
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.
Comparative Advantage
In economics all students go through the calculus of comparative advantage. People, regions or whole countries tend to apply comparative advantage to their production systems and ensuing internal or external trade. The basic rationale developed by David Ricardo has not changed that much over 200 years. The fields of application, however, are continuously expanded. Lindsay and Gartzke (2020) have applied the comparative advantage rationale to military strategy. The paper quotes 26 times Clausewitz and demonstrates the links of strategy to the basic economic and social rationale of comparative advantage. It is the politics of production that even the presence of trade may override the rationale of comparative advantage to favour local production of “operational domains” or military equipment.
In Russia’s aggression and war against Ukraine own production and trading of weapons has returned to the forefront of the concerns. In addition to the production of ammunition, the provision of drones has dominated the international arms trade related to the Russian aggression. Resources and time for production are additional factors that have an impact on availability of weapons at the right time at the right place and with the sufficiently trained persons to operate them.
The strategies that cross domains or combine domains seem the most promising. The careful analysis of your own comparative advantages or disadvantages needs to be the basis of any strategic decisions. This has been known for 2 centuries at least and is still valid in many fields of application. Additional considerations for “home production” might add to the complexity of the issue. Sustainability has also found its way into the field of comparative advantage at last. This may alter the analysis of comparative advantage of operational domains as well. Lots of unresolved puzzles still around. It will need years to sort this out despite the urgency of the Russian aggression on Ukraine.(Image: AI Copilot.2024-4-30 2 political leaders deal weapons.

AI Disruption
Many scientists started to question the disruptive potential of AI in, for example, the military’s domain. The Journal of Strategic Studies featured 3 papers on AI and autonomous systems more generally. The major argument by Anthony King is the reliance of autonomous systems on other systems mainly human operators even in the background to get these systems off the ground and maybe back again. Not only logistic support but also satellite communication is needed to guide and protect the operations. In quoting Clausewitz, Anthony King stated that war is a “collision of two living forces”. Strategy and counter-strategy will co-evolve as will attack and defence.
Jackie G. Schneider and Julia Macdonald (2024) advocate the use of autonomous and unmanned systems for their cost effectiveness. Economic costs as well as political costs are lower for these new strategic weapons. Mass fire power from swarms of drones is much cheaper than nuclear warheads and the home electorate is assumed to be more willing to accept and support limited and more precisely targeted unmanned missions. The disruption potential of AI is huge but it is most likely an addition to the arsenals than replacing them.

Time Perception
There are many different angles from which to look at time. Of course, we all do it several times a day or during boring meetings. The study by Ma, Cameron and Wiener (2024) highlights the bi-directional link of perceived time and memorability. Visual stimuli alter our perception of time. Watching a video we all make the experience that the perceived length of the time spent watching varies according to content and maybe only the cutting technique applied to shorten the perceived length. Similarly it has been demonstrated that looking for longer at an image and grasp the meaning or implicit story we tend to remember the image for longer. In courts it is a usual procedure to question the memory capacity of persons and the sources of bias. The study by Ma et al. demonstrates the impact of the size of the scene, how cluttered it is and aspects of memorability in visual perception. Our memories are co-determined by these factors. The other direction of causality i.e. that memorability determines the time perception seems equally at work. This apparent undetermined element, so far, calls for additional care when analyzing recall from memory. Memory is not only selective in terms of content, it also is subject to the impact of all sorts of visual stimuli.
Time can be many things. For humans it is everything but exact. In science we measure time with ever more exactitude and try to standardize time on the moon now. In addition to exact time, humans have perceived time and subjective versions and even concepts of time. About time to take time more seriously. 
Hospital Bias
Asking people about differences between private and public hospitals, you are most likely getting answers that the private hospitals deliver superior patient outcomes. Whereas private hospitals seem to have a positive stigma attached to them, public hospitals commonly have a negative stigma. Scientific evaluations are helpful to set the record straight again. The study published in “The Lancet Regional Health” in 2024 shows that in the simple descriptive statistics on several patient outcome indicators, this is what the data showed between 2026 and 2019. However, a more precise statistical analysis reveals that there is also a selective admission to the private and public hospitals in England. Using so-called instrumental variables approaches that account for the selection process between admission to the 2 types of hospitals (private versus public) most of the differences between the hospital types disappear. The underlying mechanism is a sorting of different patients into the private or public hospitals. Put in easy words, for a routine intervention people tend to chose the private hospital, but the more rare and difficult operations were more likely admitted to public hospitals. The number of co-morbidities (heart disease) is also of importance as they might negatively affect patient outcomes. Jumping to conclusions and reinforcing stigma about public or private provision of services hinders progress and an equitable provision of services.
The analysis of a potential selection bias can reveal the “creaming” effect of private provision of (health) services. Just caring for the “easy” or routine cases and avoiding the more difficult and costly cases has economic advantages, but for society as a whole the costs overall remain the same. A good public service in health is a definite asset.

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.
