History as Science

There are persons entering history and there is the science of history. Whereas the former persons may sometimes enter for very dubious reasons into history, responsible for killing people, the science of history draws on a whole lot of evidence, social, economic or demographic, to evaluate a person’s legacy or the merits of an epochal change. In the development of this scientific approach towards history, rather than a purely chronological, family structure or narrative-oriented approach, Marc Bloch has been a central figure. His research and exemplary own biography as student of history at the ENS in Paris, teacher and later Member of “La Résistance” is honored by an exhibition on his life and time at this formidable French institution of teacher training. In an exhibition in the ENS library you can even inspect a list of the books taken out by Marc Bloch as a student aa well as his experiences as a student in London or Berlin before the 1st World War. A strictly science-based approach to history made him an influential historian and social scientist beyond his lifetime. (Image: Salle Marc Bloch at ENS Library Paris 2026)

Nature as a concept

We all hold implicit or explicit concepts of nature in our minds. There are few countries that have “battled” over the course of history with changing and often politically interested concepts of nature. The exhibition in the DHM “Deutsches Historisches Museum” on “Nature and German History, Faith – Biology – Power” is convincing with this cross-disciplinary approach to the subject. The chronological structure of the exhibition starts with Hildegard von Bingen’s vision of nature embedded into the huge diversity of plants with almost spiritual power. Admiration of plants and the animal world, however, became an economic resource just like gold and slavery during colonization, being followed by industrialization as the epitome of man’s power over nature. Counter movements have been on the rise in the 2nd half of the 20th century. Another power struggle over how and who defines the dominant concept of nature in the 21st century. As nuclear energy, bombs and waste redefined the long-term consequences of “treating” nature, the battles about the prevailing concept of nature intensify. The exhibition in Berlin 2026 is a fine example of a historical perspective on the relationship between society, nature and technology, where the concept of nature becomes a malleable concept between the other two players or systems.

Security and Popularity

With webpages it is a bit like in the world of glamour. The more popular a webpage becomes, the more you have to invest in security features.
In a parallel webpage project, the choice has been to go for a popular name for the webpage and blog activities. After a year of sporadic blogging the site has become a regular target for hacking attempts by means of login attempts. This has led the administrator to previously allow only one single login attempt before banning login attempts from the same IP-address for several days. This does no longer allow a misspelling of the tricky password on your own behalf or the password-manager, if you happen to use one.
Security becomes a “sine qua non” condition for web-users as well as web-developers. We usually take only sufficiently care of this point, when it is “almost” to late. With 16.000+ login attempts over the time of about 1 year and 6 running locked-out IP-addresses, I almost gave up already on another domain with a more popular name. External backups become another necessity to prepare for the eventual failure to access own content and data bases.
Actually, I feel rather safe going out at night as a man in Europe, but the dangers of the global access to a web-page feels much less safe most of the time.

Magnifica humanitas

With the “Encyclical Letter” entitled “Magnifica humanitas”, Pope LeoXIV puts himself expressively into a long historical tradition of the catholic belief to be not only a religious leader, but also an institution that puts humanitarian values on the top of its agenda. As the catholic church is a globally active institution, which covers the whole life-course of individuals based on defined doctrines, the massive changes that are under way in the field of artificial intelligence asked for some guidelines to frame the church’s understanding of this relatively new “Deus ex machina” of the 21^st century. In the Encyclical, there are several mentions with respect to comparable socio-economic developments of the past. In choosing the name of “Leo”, the Pope referred, from the earliest days of his Pontificat, to Leo XIII as a particularly important predecessor for himself. The latter has made his reputation in the Christian Church with the Encyclical “Rerum novarum”, which raised awareness to the risks to humanity with an industrialization and capitalism being pursued at all costs. “Res novae” of our time, which is AI and all its fields of applications have a potential to affect the course of humanity for decades to come. Leo XIV doesn’t condemn it as the devil in machine form, but puts emphasis on the potential of AI to assist us to enhance the “Common good”. This is the task of many, not of only a few, as he refers to in his Encyclical of 2026-5-15.

Gone paddling

Similar to windsurfing, paddling has not only a physiological, but also an ecological impact. Rather than using external power the equipment requires a good sense of balance on the board and propulsion originates in your own muscles. The benefits are great for mind and body and sharing a board is the standard way of getting your regular exercise.
There are more and more stations near the sea or on lakes available in 2026-5, so that it has become a much more accessible form of exercise. Paddling is also an age-inclusive practice, since the “probability to fail“, with the pleasure of spontaneous diving, is spread relatively equal across ages. Learning curves, however, may differ substantially across generations depending on prior balancing experiences. The ecological bottleneck consists in the access to sufficiently clean water resources so that the healthy and fun exercise shall have positive long-term health effects.

Gone reading

From time to time we should reflect on our scope of reading experiences. Over time, a certain bias for probably predominantly Western European or western parts of the world is likely. Therefore, it is an interesting experience to consciously choose authors from a broader geographical background. The reading, which originates or takes its motivation from an exhibition, is a good start to broaden reading, particularly if images enliven the reading experience. The art work by Yinka Shonibare CBE on display in Berlin at the Palais Populaire manages to make this point in a colorful, compelling fashion.
It is difficult to assess what we have missed so far without having embarked on a longer reading journey. (Image: extract from Yinka Shonibare CBE, 2022, “The African Library Collection (Poets)”

Hybrid art

Bringing together 2 kinds of art makes hybrid art. Just as other fields of art have combined for example music with text to create the art form of songs as of the medieval ages, for example, the emancipation of another form of hybrid art is gaining prominence, text incorporated into or in cooperation with painting. The incorporation of text into paintings, sculptures or installations represents a drive to ise multiple channels of communication with an audience. Each might be sensitive to a specific word or sound, which creates an entry to gain attention or enlarge awareness for some cause. The “Palais Populaire” in Berlin displays the combination of the collection of the Deutsche Bank Art collection and the “Written Art Collection” to make this point with some forceful pieces of hybrid art focusing on text in art. (Image: Extract from “Map of utopia” by Qiu Zhijie, shown at “Seeing words, reading imagesSeeing words, reading images” at the Palais Populaire” in Berlin 2026-5).

Latent social structure

In empirical approaches to sociology we occasionally apply “latent variables analyses”. The aim is to uncover links between data that are not obvious in standard analyses of data. We are pretty convinced by evidence that age correlates with the probability of death. However, most tragedies are created around exceptional counter examples to this “rational expectation”. We also somehow have an intuition about the positive effect of social networks or the social fabric in a more general sense on living and survival. In some of those latent variable models we find evidence for an underlying factor without being able to properly name or frame it. Hence, as social scientists we continue to be interested in ways to make latent social structures more visible. With such an approach in mind I visited the exhibition by author and photographer “John Kolya Reichart” in the “Schöneberg Museum” entitled “Die Kette” (The Chain, 2026-5). The start of the chain is a familiar person in your neighborhood who leads you to the next person and so on. It is explicitly a non-random procedure, which complements proceedings of strictly random sample selection of survey methodologies. The sources for bias outcomes are multiple, however, an underlying or latent social fabric of a friendship and support mechanisms can be shown. Besides the b/w portraits and audios, giving a justification for the choice, the documentation of the process of production gives more insights into the risks and potentials of this form of insights into latent social structures.

Nothing changed

It reads like an entry into a personal diary. The poem “Darmstadt, 4. Januar” by Renate Schmidgall (2025, p. 24) reflects on the obsession with change. The sky shows traces of airplanes, which have passed some time ago. Trees age slowly, a pigeon sets off. “Nichts ist anders als gestern,” (Nothing is different from yesterday, then suddenly a poem finds again its space in me, …). Nothing changed, and yet, suddenly, all is different again. Motivation sets in and time appears rather short.
In “Donnerstag” (Thursday) Schmidgall (2026, p.30) notes a daily routine and the planning of today, even the day after tomorrow. Emptying her paper basket, she finds a quotation from Bruno Schulz she noted previously. “An allem schuld ist der schnelle Zerfall der Zeit.” (The fault of everything is the rapid dissolution of time).
Time is portrait in these two poems as both a moment-specific personal experience as well as the short-cut description of a society-wide trend. Just, as if time was the driving force of change on both levels, even if we know it is not time in itself, but other forces are at work. “O tempora, o mores” as Cicero stated, appears to be still valid summary claim. (Image: Neue Nationalgalerie Front – WZB (Stirling architecture) in background, Fog installation in sculpture garden 2026-5).

Time in poetry

Some might argue poetry is all about time. It is a perfect way to “decelerate”. Reading pace, in most instances, slows down considerably. At least the first time reading is frequently a stop and go process. A few examples of poetry may hit personal trigger points. The random collection of poems I consulted in the “Lese lounge” in 2026-5 contained each the topic of time in one or the other form. Renate Schmidgall (2025) carries time indirectly in her title “Kein Verlass auf Uhren und Gestirne” (Don’t depend on clocks and stars, own translation). She creates new metaphors like “Am Kirchturm rostet die Zeit” (p. 12 On the church tower time rusts). This sentence precedes the sentence which became the book title. Time is also envisioned a bit like an onion in another metaphor “die Uhr schält rückwärts die Stunden“ (the clock peels backwards the hours). So much to gain with so little time spent with poetry. (Image: Bronse in Jardin des Plantes, Paris, homage to Saint-John Perse 2026).

Taking a break

The time a researcher spends reading is still above average, I suppose. Even in times of AI doing astonishing summaries of documents and texts in general, we still need to check the output by reading as well. Taking a break from data compilation and writing, it’s time to do other reading. The Staatsbibliothek tries to lure people studying and researching there into their „Reading Lounge“. In 2026-5 the proposed reading is poetry. Based on the recommendations by an expert group 10 titles of German and 10 translations of poetry are available with direct access for onsite reading. The shift from on screen reading to paper based reading gives your eyesight a break. Your mind wonders off to something else. Much better concentration and new synapses afterwards. Why is still so difficult to take a break this way? We are working on it.

Litfaß Advertisement Column

Berlin has renovated some of its early say notice boards and advertising columns. The original „Litfaßsäule“ has already the round column shape where you clued a poster on the sirface so that it was visible to several persons interested to look and read. After more than 150 years after its invention, Berlin has digital advertising columns which resemble the original Litfaß design. Rather than the spectator walking around the column, the column now turns around in a steady manner so that nearby you can see the whole advertising content from all points in the neighborhood. Simple change, but a remarkable improvement in the reach of the advertisement. Retro-lighting increases the duration of the effects as well. Mass communication and commercial innovation can sometimes just improve on an existing marketing channel, and still reach a specifically targeted audience.

Renovated sacred architecture

The 18^th century catholic St-Hedwig Cathedral in Berlin has been renovated in the 2020s. The sacred building benefits from its central location in Berlin near “Unter den Linden”, Staatsoper, Staatsbibliothek and Humboldt University. The remarkable round shape of the church and its dome appear small from the outside between the high buildings in the surroundings. The size becomes more visible from the inside. The renovation made the choice to clearly define the center of activities again with the “altar” in the middle surrounded 360 degrees by the audience. Every visitor will be fascinated by the sound design of this renovated sacred architecture. The organ, orchestras and choirs have to handle this with care. Speech is transmitted with astonishing clarity. The sober interior focuses on essentials and might give the impression to be in a protestant church rather than a catholic one.
Silence or rain on the roof become an experience in itself, believing or not.

Post-sacred architecture

As with our human bodies, and in many instances already, sacred architecture follows a life course pattern. The thriving religious communities build and expand their faith to larger audiences. In these expansionary phases of the faith many monumental buildings, known as sacred architecture, as well as splendid interiors or artefacts enter the “built faith”. After the peak of membership and in periods of contraction, the question of how to scale down the splendors starts to arise.
Eventually, the ceding of the sacred architecture to the non-believing communities comes into consideration. The sacred architecture needs to find its place in the evolution of societies as well as urban and rural local space. Depending on the intentions and resources of communities, post-sacred architecture has to redefine its purpose for its own survival.
An interesting example of post-sacred architecture constitutes the “Friedrichswerdersche Kirche” in Berlin. The use as a historic exhibition space for sculptures of the 19^th century works particularly well in combination with an active program on art, architecture and history. The statue by Ludwig Winckelmann (image below) depicts the reflection on and about a miniature sculpture in space. The post-sacred use of this fine and luminous architecture continues to reach an enlightened audience.

Valuable Donations

The of a donation to a national gallery is often a curse but may reveal only much later as a blessing. More galleries across the world give due credit to their generous donors. The collection of impressionist paintings by Caillebotte figures today very promising in the Musée d’Orsay in Paris. The fine collection by Chistoph Müller endowed to today‘s “Kupferstichkabinett” exposed in the Gemäldegalerie in Berlin has been on display in a small room. The „Kräuterblätter” (herbes on paper) by Kolbe 1815/1824 are fine pieces of etching with a focus on what might get lost in our biodiversity in coming years. Old trees were surely on his list (Oak trees 500+ years old). A collection of depictions of herbs and flowers a part of an ecological treasure which the generations after the painter and eventually the collector Christoph Müller began to value a lot. Some collectors are far ahead of their time by treasuring the past. (Image: Extract of „Kräuterblatt mit Schnitterin“ Kolbe 1815/24 Donation Christoph Müller shown in Gemäldegalerie Berlin 2026-5)

Portrait of or about

In some galleries or for curators of an exhibition, the crucial question is not only the overall message, but the best positioning of artworks in the available space. In many national galleries what hangs next to another piece is rarely seen as an opportunity for exploration and experimentation. A recent visit to the “Gemäldegalerie“ in Berlin allowed to explore the vicinity of 2 paintings, which are very different in appearance. The one (by Pierre Subleyras 1740) is just entitled “Portrait of a woman”, the other one next to it, “Virgin and Child Enthroned, with Angels and Two Saints, Domenico Mondo 1773). The former portrait has almost a modern touch to it as the beauty consists in the simplicity of the person depicted, whereas the latter painting portrays a rather empty message of splendor and power. The conscious confrontation of portraits or paintings with each other is the high art of curatorship. It is even more pointed than a guided tour of a gallery as the simultaneous rather than the sequential confrontation is the issue.

Woman artist scandal

The painter Hermine Schmidt-von Preuschen, little known today, had to face strong forces in the established art community of her time. The skills and audacity she displayed at an early stage of her career as painter is epitomized in her work “Imperator Mors”. This painting dates back to 1887 and was rejected by the art academy in Berlin for their official exhibition. The woman artist was already at that time confident enough that her painting was of sufficient quality to deserve to be not only considered in the exhibition, but also to be seen by larger audiences. Similar to the refused painters of the impressionist movement, she decided to mount her own exhibition. The turnout to this proved to be quite a success according to the press cuttings presented as part of the exhibition in Berlin at the “Alte Nationalgalerie” 2026-5. Maybe it was the intended philosophical topic or message that killed the chances to be part of the art academy exhibition. “Imperator Mors” shows death or a skeleton to be the ultimate ruler of our fate. For all those who believe in some sort of life after death, this can be viewed as a “Scandal” in itself. The scandal created with such a depiction probably overshadowed the fact that the provocation came from a woman artist. Still very avantgarde for the end of the 19th century.

Brancusi polyartist

The joint exhibition by the “Neue Nationalgalerie” Berlin and the “Centre Pompidou” Paris has the simple title “Brancusi”. The name of the artist Brancusi stands for a very singular approach to take sculpture into the 20^th century by way of abstraction. Brancusi used all sorts of materials like lime stone, bronze, wood and marble. Additionally, he was very conscious of the fact that especially for sculptures the “mise en scène” plays a vital role. Brancusi excelled in this in a rather unique way, mostly by confronting different materials with each other. Sculptures, for him, were architecture in miniature. Such a polyartist approach to sculpture pushed him to use photography and video to not only promote his own work, but to exploit these relatively new techniques to enhance the effect of his sculptures.
Maybe it took almost 100 years that by means of the “not-so-social media” not-instant, anytube and tikytok, this “modus operandi” would capture a whole generation of youth to follow in his footsteps without knowing it. The polyartist Brancusi is a unique milestone, not only using lime stone, on the trajectory of sculpture beyond the early 20^th century. The links to other innovative artists chosing abstraction, Picasso or Modigliani, as well as musicians like Eric Satie, reflect the importance of social networks for mutual encouragement when treading new paths in art.

Beeple Deeple People

The “Neue Nationalgalerie” in Berlin hosts in 2026-5 the work by “Beeple” artist Mike Winkelmann together with the “Andy Warhol Robot K-456” by Nam June Paik. The re-interpretations of robots and the imagined effects this new media has or shall have on our lives, this is the subject of a critical projection and the artist’s chosen form for a projection into the future.
In 1994 the “Andy Warhol Robot K-456” prefigures the pervasive decoration of the human body with screens as a futuristic way of communication with others. The communication practices in 2026 have changed with software and applications like DeepL, which allow real time translations of speech to our neighbors or distant cultures.
The installation “Regular Animals” brings to our attention the power of images in our daily communication. Warhol built his art around the topic of pop culture with the visual heroes of, for example, Elvis Presley and Marilyn Monroe as the best known pop images or icons of his time. In Beeple’s work, the dog robots’ conversation is only via instant images. These images are AI-edited and distributed rapidly at random across space, the floor in a well-delimited space. Space does no longer matter as distance as it is passed instantly. Perception and reception are transformed into a power-play via images and distribution channels. We are all transformed into “Beeple Deeple People” without noticing it, aren’t we?. About time that social science or sociology of the visual recons with these not so new facts of communication in the 2020s.

Psych-inflation

The economic narrative and measurement of inflation is incomplete without the proper account of the psychology of the price building process and mechanisms. After the 2 previous oil-crises of 1973 and 1979, the panic about not having enough oil and derivatives within the coming months, has lead to prices increases almost instantly. Despite the fact that there is enough oil floating on ships and in pipelines for 3-6 months, depending on estimates, the psychological effect of being eventually short of oil creates “Psych-inflation”. Oil markets use the “Angst of disruption” to make additional profits on people and enterprises’ hoarding behavior. There are powerful interests to exploit such potential shortages as it is a suitable time to reap some extra profits, particularly for those who knew early about a likely military conflict.

Light Locomotion

There are many politicians who have an innate tendency to move in the direction of any flash light or camera. Tenagers in the age of the “not-so-social media” have a similar reflex. More seriously, Science Advances, has presented a fully autonomous robot with such a behavior. In fact this form of light locomotion is named the “twirlbot”. It has been developed by Chi Chen et al. (2026) as a new kind of robot that can be directed using light impulses, as only energy source for moving towards the light source. The from of locomotion is inspired by nature (bionics) and more precisely the “tumbleweed” way of moving, better rolling forward, driven by wind energy. The tumbleweed-inspired rolling robot, short “twirlbot”, does not need mechanical devices, just energy in a specific frequency range of light, which provides the heat for the photoactive, otherwise passive, bilayer strips. The polyhedral geometry of the twirlbot allows omni-directional locomotion. It really resembles the light active politician or any posing in the spotlight while doing the “loco-motion” (Video Link performance by “Little Eva” in the early 60s or a late 80s version by Kylie Minogue).

Random randomness

In textbooks or courses of statistics, just as ordinary experiences with throwing a dice, we assume the perfect dice. This means the dice is assumed to have equal probabilities to roll on each side. Further, each throw of the dice of a sequence has an independent equal chance for each number to come up. To determine a “fair” dice we would throw the dice a thousand times to check, whether the probability of each side is about equal. However, the world of dices is not perfect and temporary or persistent margins of deviation are part of the real world. The weekly lotteries demonstrate this over and over again. Playing around with different shapes of dices makes the issue of probability tangible. Well worth to explore further empirically as well as a topic for inspiration of new approaches to learning about statistics. (Image: Dices produced by “devinsdice” Berlin 2026-5-5)

Family Archaeology

The archaeology of family bonds is an interesting branch of both archaeology and genealogy. The mixing of hunter-gather populations with settled populations seems a rather ancient fact (study link). Analytical DNA comparisons reveal that nearby groups had indeed contact and even intermarriage occurred more than 5.000 years ago (Mattila et al. 2026). The evidence is based on data from a cemetery where several persons were buried in the same grave.
The study by Blöcher et al. (2026) demonstrates that in the late phases of the Roman empire along the Roman frontier in Germany a mixing of Romans with local populations a similar process took place. Whereas genetic structures persisted until the 6^th century, the Central European genome as we know it today refers back to the 7^th century. The inter-generational transmission seems to be an important driver of diversity. The high infant mortality together with an earlier mortality of women than men at that time show the accomplishments of modern medicine to safe infants and mothers from the hazards surrounding family formation and survival.

Given then Chosen

Family is first given and only later in life family becomes a matter of choice. This is a rather sequential perspective on family matters. A lot of ethnological as well as sociological research shows that the shadow of the given family can reach long into an individual’s later life. It is essential to be or become aware of the mutability of what constitutes a family. The ethnological variability across the globe of the norms and legislation that govern families is amazingly broad. The interference of religious beliefs and practices have always attempted to gain access to the nucleus of family life as an attempt to influence the “given part” of family.
It is a much more complex issue to understand and research the “chosen part” of partnership trajectories in a broader sense and from a life course perspective (Fasang et al. 2024). The social background and upbringing in a broad sense have a lasting impact on most people. However, there are enormous degrees of freedom to later on choose your friends, family or families. Societies across continents have chosen and invented particular rites of transitions between families and how to bridge networks. It is amazing that we tend to devote so little thought to this nucleus of our societies.

Pictures at an exhibition

The playlist on Spotify, which accompanies the exhibition “Unforgettable” in Ghent, is an interesting extension of the unforgettable artists into today and tomorrow. You may be inclined to share your opinion in the way Maria Iskariot does it in “Dat find ik lekker” or more like Sophie Straat in “Dansen met de dood”. Anyway, women artists are coming front stage and this is great news despite all the backlashes we, unfortunately, witness in the 2020s. The curator of the playlist Murielle Scherre has managed to take us, a bit like the exuberant Modest Mussorgsky in his “Pictures at an exhibition”, beyond the marvelous exhibition rooms to a broad exploration of contemporary women artists’ world of imagination in music, visuals and songs. A great intergenerational accomplishment.

Forgotten but Unforgettable

Many women painters and artists who worked during the 17^th and first half of the 18^th century have been forgotten until recently. The galleries of the time and many years later gave little attention to the women artists of that time. Most of them were relegated to be of minor importance in the course of art history. The exhibition of the Museum of the Fine Arts Ghent in Belgium has accomplished to rectify this place of women painters in art history. The fine pieces of art, ranging from painting to sculptures, were frequently signed by men, probably to achieve higher market values and become visible in the public sphere at all at their time.
The exhibition is a kind of a revelation of how difficult it was for women to move from an “object of art” to be the subject painting including painting themselves. This also dealt with the view or regard of others towards women. Additionally, the exhibition features a section on “Social Expectations”, which deals with the expectations of the Flemish and Dutch societies towards women. Family values, marriage, wealth and social status were of utmost importance.
These women painters were forgotten far too long, but have staged their comeback as “Unforgettable” in the 21^st century.

Jobs First

The Berlin demonstration of the 1st of May has chosen to put „Jobs First“. Jobs before profits is a widely accepted claim by trade unions to highlight the importance of work in our societies. Particularly in times of robots and AI taking jobs away, this motto is well chosen as a principal risk in 2026. The current technological innovations seem to aim primarily at the maximization of profits for companies rather than the benefits for society as a whole. The Berlin parade on the 1st of May managed to achieve a great mobilization, which is a great success for the labor movement and a demonstration of power and solidarity when in many countries basic employment rights and even the 1st of May as a social tradition is attacked.
