In a bookstore which sells books in English or American language we find lots of biographies or autobiographies of politicians. As a politician you don’t even have to be out of politics when your biographical account or your own view is published, let alone be written. Publishers seem to hunt politicians who made headlines, no matter good or bad. Outside the EU you can always sell biographies at half price, if the volumes sit for too long on the precious shelves of bookstores. Most of the biographies are found in the history section of shops or libraries, however some show off in sections like politics (if not dead for too long) or in the business and management sections. Leadership is a big issue in the latter disciplines, but the psychological or sociological literature starts to meddle with the received wisdom of how single person leadership is in fact facilitated with the many great people around the sometimes outstanding single person. Maybe the focus on a single person is an easily understood and simplifying concept of leadership. In the case of Obama (2x) two single historical accounts complement the one person focus. In 2025 Michelle Obama skipped the funeral of Jimmy Carter where she would have had to sit next to Donald Trump (according to the Daily Telegraph and probably endure small talk). Politics appears to move in circles and politicians might find themselves encircled. 
Health data
2025 will be a crucial year for health data across the EU. Germany introduced the electronic patient card, which can store basic information to then access data in the health insurance cloud for medical doctors, hospitals and other related health services. Potentially this is a great step ahead as some tests do not have to be repeated if they had been completed recently before already.
In pseudomised form, research may draw samples from such databases to enhance our science based understanding of disease. The evaluation of public health interventions becomes easier and medium and long term efficiency of measures can be assessed in many instances.
The Belgian research using health data has met to discuss the potential and limitations to link health data to other data sources to allow more complete and more complex analyses of health and disease processes. Another extensive data source sits on our smartphone. Collection of steps walked, sleep patterns or heart beats give valuable insights into a person’s own contribution and care about personal health. Although data are frequently incomplete, researchers are used to estimate missing data on the basis of existing or comparable person’s data. The basis for improving health for all are quite promising, data handling and linking them will be a challenge to the competence of all stakeholders and everyone involved in better health. It will be stressful before it becomes a routine. 
Sexual harassment
Under the broader topic of violence against women, we count gender-based harassment at work. The recent report of a survey based on more than 100.000 persons in the European Union in 2021 shows the shocking amount of violence in the last 12 months as well as violence experienced over a lifetime. (Source Eurostat Link to pdf report) These data have to be interpreted with care since it is a well known statistical phenomenon that in some countries such misbehavior is reported and talked about more easily and openly than in other countries. Therefore, the countries with the highest figures, for example in Nordic countries, there it is safe to talk about the issue (Nordic paradox), whereas in other countries violence against women and sexual harassment at work are still much less talked about and addressed in public. Italy even deviated from the joint EU data collection.
It is important to address the topic in the media and lift the cover-up attempts in many societies. This is a process over time, but it is important to continuously raise awareness about the problem. We have made a lot of progress on more equal treatment of women in recent years in most European societies. However, the is need for a “zero tolerance” of violence against women and the sexual harassment at work, which prevents women to take equal shares across all professions. Monitoring the process is an important step, which is necessary to target safety measures in a better way. Further details of the statistics are needed as well to address intersectionality as well. Young women tend to suffer more than older ones. Maybe the latter ones have learned to be more careful to avoid or evade critical situations. It is, however, men who have to reconsider their behaviour towards women at every age, at work as well as at home. 
Bi-directional Sleep
For most of us bi-directional sleep is a question of sleeping on the left or right side, or on our back or front, head left or right. In immunology bi-directionality of sleep has another meaning. The immune system is linked to sleep in a bi-directional manner. Good sleep enhances the immune response of cells (direction 1) and infected blood cells for example send a signal to the brain to extend sleep. The study by Huynh et al. (2024) in Nature has demonstrated this bi-directional mechanism. It allowed mice who slept well after an imposed heart attack to recover in a better way than those whose sleep got interrupted during the experiment. The most natural response to a heart attack or acute coronary syndrome is more sleep. This is induced by an inflammatory reaction in the brain, which « orders » your body to increase deep sleep. 😴 Sleep is more than just rest, it may be part of healing. ❤️🩹 (people looking at Caspar David Friedrich „Infinite Landscapes“, exhibition Alte Nationalgalerie Berlin 2024)
Theatre Artists
Performances in the theatre are called pieces. The artists performing are actors of a play. The « Théâtre de la Madelaine », which celebrates its 100th anniversary in 2024 puts on a new production in celebration of the biography of the famous painter Claude Monet.
«Dans les Yeux de Monet » is the inspirational title of the play written by Cyril Gely and scenario by Tristan Petitgirard. Looking through the eyes of Monet puts you into the sometimes tormented head of the great artist. The challenge Monet faces is his very own perspective on a new vision for painting. In order to capture the impression of the cathedral of Rouen on him, he experiments with colours and lighting to capture just the right moment in time. Interesting to remember, there is not just one single moment he paints, but many versions of it with each realization offering a special insight or impression. Just on the sideline we learn about the importance of plurality rather than the one and only unique moment in time.
His own personal difficulties of sufficient funding for his art work and the depression he struggled with are well represented in the script and by the actors.
Galerists as well as donors (Mäzene) encourage artists, but somehow may also contribute to the pressure on artists to produce more creative work. Precariousness of living and living conditions are often a corollary of creativity or the creative process. This is a usually forgotten part of the biography of many past and present artists. Artists have and still contribute so much to humanity, but in most countries the public or private support for artists is sketchy. This remains a societal challenge particularly during times of employment and skill shortages in OECD countries.
Forced Living Space
The „Topography of Terror“ hosted the book launch of the research project on „Zwangsräume“ (forced living space or forced homes). The cooperation of an impressive network of organizations (Aktives Museum Faschismus und Widerstand in Berlin e.V., Koordinierungsstelle Stolpersteine Berlin, Alfred Landecker Foundation, Metropol Verlag) has achieved to uncover the forced relocations of thousands of German jewish people from rented place to another one, thereby regrouping and cramping Jews into ever smaller living spaces in predetermined houses within Berlin. Through this horrible step by step expropriation and extermination terror was present and visible all over Berlin. The online documentation and data access allowed citizen science projects to accompany the research and actively contribute to enlarge the data investigated, analysis and dissemination of the findings. The continuation and extension of the project is already in preparation and seeks additional funding and volunteers. The traditional book publication helps to provide an insight into the thorough historical research which started with a more adequate definition „Zwangsräume“ than the previously used term of so-called „Judenhäuser“, since the houses had and kept a mixed population sharing the living spaces until deportations of the jewish persons forced into ever smaller living spaces before. The property of the deported persons was recovered by officials from sealed apartments and sold mostly as bargains on auctions or just redistributed among officials in need or with special merit for the Nazi-movement. This adds an intergenerational dimension to the project that is also worth looking into in the next phase of this extremely valuable project based on large online archives from original register information and other documents.

Happy Employee
The research on happiness, subjective well-being or overall satisfaction with your life is also an empirical question. Analyses of being happy donot only focus of overall happiness, but look much more into the details of happiness. Beyond the tricky longitudinal observations of happiness it is common scientific practice to deal with subdomains of happiness like satisfaction of employees with their job, satisfaction with one’s job beyond the honeymoon and hangover effect, best known from family studies.
Each of those subdomains has a significant effect on overall happiness. The novel “Happy Life” by David Foenkinos is an interesting example which focuses mainly on the subdomains of job satisfaction, satisfaction with private and romantic partners as the major domains of a happy life. As developed in the novel, people make job changes to re-orientate professional careers or reset their private life. A low point on the happiness scale in one domain might be compensated by higher levels in another domain. These impact from one domaine to another might have substantial time lags involved as well. More drastic resets (à la Foenkinos) can be avoided through focus on other subdomains of overall happiness as well.
How happy are you with your housing situation, neighborhood, your pet, your physical health? There a multiple +/-spill-over effects to overall happiness. Reading a novel might be one as well, just take time reserved to yourself.(Image BnF expo “women in sport”, 20024)
Happy Maths
The link of maths and happiness is not straightforward. Individual accounts of a happy (euphoric) or unhappy (dismal) life are mostly referred to psychologists for treatment. The biografies (documentaries) or fictional biografies told in novels or cinema allow to trace the changing moods of the personalities over time. This resembles life course research. In happiness research social scientist ask questions like “Overall, how satisfied are you with your life“. Measured over time or coded from biografies this allows to reconstruct happiness trajectories. At this point the maths of happiness enter the stage. Long periods of observations yield interesting patterns of curved lines, rarely simple linear trajectories. Social scientist speak of within person variability in contrast to between persons variability. After all, the (short-term superior) happiness of your neighbor might simply be due to the fact that they are doing drugs.
Whatever, try to remember a bit of your high school maths and the bore to deal with “curve discussions or sketching” beyond the manifold shapes of your classmates. Lots of interesting information derives from growth or decline rates, tangent lines, stationary or inflection points. Different starting points or so-called intercepts vary between individuals as well as he potential to cross the Zero-line on one of the axes. Additionally, in geometry you would compare syncronicity of curved lines as well as forms of symmetry for the curve(s). This will simplify or comlexify your perspective on the happiness trajectories of people or characters in a novel.
We are so used to narratives or videoss with a happy end, yet we appreciate the complex trajectories and (multiple) troughs main characters have to pass. Novels teach us about tricky inflection points and subsequent trajectories as well. The maths of happiness, however, is rather simple in comparison.

Happy Life
There are countries in this world that want to prescribe to their citizens what constitutes a happy life. Religious beliefs are another powerful instigation of what may be called a happy life now or in the future. Most people on earth, however, have their very own idea about happiness and how to get closer to this moment, phases or destiny of their lives.
Happy life is also the title of the novel or „une fable optimiste“ by David Foenkinos with the almost programmatic title „La vie heureuse“. It has been qualified as a bit absurd, but at the time of celebrating 100 years of surrealism, this fits into the surreal world episodes and narratives that surround us. The novel is full of ups and downs for the major characters, which reflects the inevitable links of happy relative to unhappy moments in life. The pseudo experience of death allows to press a kind of reset button in life after which love and life can start afresh. This might not work for all us as Foenkinos seems to tell us with the choice of the dedication and citation of Charlotte Salomon „On devait même, pour aimer plus encore la vie, être mort une fois“. Charlotte Salomon, however, lives on through her formidable artistic work accomplished in her short life.
Stress Ageing
The relationship between stress and aging is a complex one. Stress is known to accelerate aging and aging caused different reactions to stress. In short causality does not run only in one direction. Additionally new research published in Nature Medicine 2024 demonstrates that different genetic preconditions determine different response patterns to stress and subsequent brain aging. From anecdotal experience we are well aware of different persons coping very differently with stressful situations. Mastering of various coping mechanisms may attenuate the stress experience but the impact on preserving our brain remains an open question. Various other forms of lifestyle conditions like drugs and smoking cause specific forms of brain damage as well. 2 separate forms of dementia can be identified from brain MRI-images as well. The brain is no longer the black box of missing information about what is going on in humans. Put to the right purposes this is good news. (Image: break dance shooting Paris St Denis 2024)
Alzheimer Research
Alzheimer disease has reached unprecedented levels in line with population aging. The study by Martino-Adami et al. 2024 has raised the hope that more people can receive an early diagnosis of Alzheimer and potentially start treatments. The study used plasma biomarkers rather than much more expensive and rare MRI scans for diagnosis. The rather exceptional results allow even to test for severity of Alzheimer according to established evaluation measures. Additionally, the probability of an Alzheimer trajectory on a time scale is feasible. The authors suggest that the data and statistical methods applied allow to identify Alzheimer before the outbreak of impairments. The data sample stems from “patients of advanced age visiting primary care”. This remains a limitation for generalizations, but the hope that other studies test the same approach with samples from younger populations will spur additional investments into such research. The list of institutions and foundations that contributed to make this study possible is really long. Thanks go to all involved, researchers, donors as well as the reviewers and editors of the journal. (Image Paris Metro Help Column 2024)
Olympic salary
According to an information in the Wall street journal 2024-8-6, the self-reported annual income of top athletes who participate in the Olympic games Paris 2024 for example has a large distribution from those who go into debt to finance their personal or national dream and those who have already a comfortable income due to their sports commitment. 26% of athletes are reported to live with less than $ 15.000 per year only. However, at the other end of the distribution of income we have 23% of athletes earning more than $ 100.000 per year. A lot depends on the kind of sport you practice and the earnings of sponsors and “maezene” or professional attachments to professions that rely on physical strength as well. The average or median of the distribution is at a decent level albeit far from spectacular for the amount of effort a d time the athletes devote to their activities. Many other professions earn much more accompanying the athletes and those professions are also a likely later steo in a sportsperson’s career. Life course analysis remains an important field of study which informs the chances of winning medals in Olympic competitions.
Olympic Equality
Of course, first of all the Olympic Games are about making a difference with respect to your opponent. However, there has been a thrive to achieve an equality of genders for more than 100 years as well. Women had to battle such a long time to achieve the right to participate in the Games in the same disciplines as men. For the first time in Paris2024 men and women are represented with the same amounts of athletes. Each gender is participating with 5.250 athletes and astonishing progress has been made to ensure that male and female athletes perform in the same or similar disciplines. Even if it took decades for women to run a marathon at the Olympics, the inclusion of a triathlon for women was already much more rapid.
This constitutes a real milestone in the progress towards equality in Olympics. Equal numbers of athletes is a quantitative form of inclusion, the qualitative level of inclusion remains to be accomplished. The qualitative dimension consists in the inclusion of women at equal footing in media reporting and sponsoring. On the organizational level of the IOC the organizing committee is still dominated by men and statistics on the accompanying teams of coaches, therapists and representatives a lot of progress still needs to be accomplished. Paris made already a huge difference and several exhibitions of the “cultural games” around the city during the Olympics 2024 make this point quite forcefully.
The sociology of the Olympic Games has a lot of topics. It is great to see the progress made in Paris on Olympic Equality, after all “égalité” figures prominently in the definition of modern France.

Live longer
It is an old dream of mankind to live longer and longer. The Covid-19 pandemic has taught us many lessons that there are powerfully viruses and their continued mutations which threaten this. Life expectancy declined slightly during the pandemic and we learned that long Covid is yet another threat to our life expectancy. Scientists have found other sources that are crucial for survival. Like sepsis, it is the constant inflammation processes in our bodies. Long working times, stressful commute to work and interrupted or shortened vacations all contribute to keep inflammation at higher levels than is healthy from a longevity perspective. The research note published in Nature on the inflammation enhancing protein IL-11 highlights the chain reaction process of inflammation causing cancer and autoimmune disorders and diseases. Hence, it is essential to watch the biomarkers of inflammation and probably adjust our lifestyles accordingly. The sources of inflammation are manifold, but the potential rewards to address the issue are huge as well. Among the easy to address sources is nutrition, exercise and working life. Changing just a little bit here and there can make already a change. Monitoring how you feel about such changes puts you on a learning curve for your own inflammation levels. Vacation times are also perfect for adaptive behavioral changes. We just need to keep trying.
Dietrich Gabin
In French cinema Jean Gabin is a much adored person. Equally, Marlene Dietrich had, probably an even more far reaching international career. Both were accomplished and successful actors long before the 2nd world war broke out. In the U.S both fell in love and had a long lasting romance together. Their war time activities and “engagement” in fighting Nazi-Germany were extraordinary. It meant that both took active roles to use their charisma to mobilize people and soldiers to fight for freedom.
Shortly after the war then, both made a last attempt to work together in a movie production, but it could not unite the couple again. The “Deutsche Kinemathek” displays currently a page from the Diary of the “Diva” to underscore to what extent “Dietrich” was depressed about the break-up of their longer lasting love affair. Some say Gabin was the only person who quit her, all (most?) other relationships were terminated by the Diva. The junctions of biographies are hard to predict. The circumstances of the 2nd world war and internalized civic obligations to fight for freedom and democracy were wholeheartedly shared by both, but eventually they grew apart nevertheless. Tough experiences even for the much adored persons on the forefront of the stages worldwide. There seem to be many instances of repetition of the same story not only in movies, but also in real life.

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. 
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. 
Heroines
In youth we are open for a wide range of influences. Heroines in children’s literature, picture book or cartoons look back on a long history as successful influencers. Creation, transmission and criticism of stereotypes are all part of the scientific reflection on heroines and heros. Nowadays, influencers have taken over picture books through the use of more compelling videos.
In the 1950s,1960s and 1970s picture books or cartoons dominated the influences before mass media like television became more absorbing, addictive and powerful influencers. Children’s books are passed on from one generation to next generation. The French-speaking world (and beyond BBC reference) has witnessed the success of the illustrated booklets of the young “Caroline” (Hachette) and “Martine” (Casterman) exploring the world. Parents passed on their collection to children and had their own parents read the stories to their grand children.
Well, that’s how intergenerational transmission of cultural heritage has worked for a long time. It describes the basic social mechanism. Nevertheless, new forms of influencing emerged with new technologies. Successful illustrated narratives like “Caroline” and “Martine“ were adapted as television series as well. In France you could chose your side of either explorations with Caroline and her group of animals or the adventures of Martine.
Ideally it would be an occasion for the families and friends to discuss pros and cons of each character and, thereby, become aware of what is a stereotype, at least at a later stage of the life course. Gender stereotypes have evolved and to observe 2 boys colouring Martine images in public (Brussels book fair 2024, image below) was a positive surprise. It almost felt like a real world experience of the AI-enabled Barbie explorations. 
Fertility BPS-SPB
Fertility is another example of the co-determination of the biological, psychological and societal spheres of life. The latest available data for Germany and Sweden in 2023 show a remarkable decline of 10% in the seasonally adjusted Total Fertility Rate (TFR) in both countries (Bujard, Andersson 2024). The TFR was at 1.3 in Germany and 1.5 in Sweden. This means both countries are well below their population replacement rate. In both countries the populations will shrink further. There are no easy answers to the question: why?
The co-determination of the biological, psychological and societal spheres of life seems to be combined driving force. The biological clocks are ticking for women who delayed birth. Maybe pollution of drinking water or PFAS, nanoparticles of plastics disturb fertility. Psychological reasons such as increased anxieties due to the Covid-19 pandemic, lock downs or closed schools have left parents without adequate support for 2 years. Isolation or loneliness could have delayed partnerships and fertility as a consequence. The social environment has also provided additional uncertainty as the cost of living has risen and affordable housing for families is scarce in both countries.
We have probably underestimated the effects of the “Zeitenwende” on people’s mind sets. Sweden has suddenly sought to join NATO to achieve a broader military safety net for its people. In Germany the experience of damages due to war or as a consequence of Russian occupied territory is very present in people’s mind. The war of Russia in Ukraine may have increased uncertainties, anxieties beyond the immediate effects of higher living costs, interest rates or prices for energy. At best fertility might only be delayed for some years, but the consequences of shrinking populations need to be taken seriously. Making societies more welcoming for children and their parents is part of the solution. 
Sleep biology
Biological processes work hard during our sleep. Our immune system in particular benefits a great deal from undisturbed sleep. This is the simplest summary of the study by Kabrita et al. (2024).
We can study the temporal expression pattern of major histocompatibility complex MHC class I for example in mice. 2 groups of sleep-restricted versus normal mice reveal the biological impact of sleep restriction. In comparison to the control group sleep restriction in mice produced a bimodal pattern of Splenocytes with higher protein levels during the resting period. Such an increased protein expression during resting periods indicates a “preparedness for a potential infection”. Sleep recovery, even if short compared to the longer sleep restriction, allows to return to the baseline of protein levels. The good message is that at least mice seem to recover rather quickly from sleep deprivation with their immune response system.
The biology of repeated phases of longer sleep deprivation could inform us on the implications of sleep deprivation on aging processes. The biological responses in single event sleep deprivation seem to show a fast recovery pattern. Probably it is worth studying the same recovery process of groups of young versus aged mice.
Anecdotal evidence from myself indicates that recovery after sleep deprivation in older humans is no longer as fast as at younger ages. Behavioural responses might be less sleep deprivation (less fun) or longer recovery periods (stay in bed longer). The behavioural response of humans appears to be an obvious one. Instead of either or, we tend to go for both at the same time.

Biographies
The biographies of painters, composers or artists in general can be reconstructed by use of their major works. The biography of René Magritte by Eric Rinckhout (2017) has chosen this way of a retrospective in images and explanatory texts. The biography is built around 50 major images starting with the first one by Magritte at the age of 28. “Les réveries du promeneur” (see below) deal with the confrontation of Magritte with death, suicide and the difficulty to find rational answers to all those questions of why this happens and what becomes of people who experience such a tragedy.
His own childhood was affected by such an event concerning his own mother who suffered from depression. Coping with the evolution of psychic illness over years and the absence of a supportive father have posed a steep challenge for the young person. Creation of art became a coping strategy as well as a relief for those who manage to eventually cross the bridge into their own life leaving behind the bad experiences. J.J. Rousseau was an influence on Magritte as well.
Finding your own destiny and your own style is a process. This process evolves over years. The chronological sequence of 50 images allows to follow the path taken. Thereby, it becomes possible to open up the personal learning and working trajectory of the artist. In retrospective perspective it seems often logical that one style or period of painting follows on from another one. However, in the forward living of the creative life many choices are heavily contingent on other circumstances. Influences of friends, exhibitions, reading, cinema, private or financial situations may determine the creative choices simultaneously or one at a time.
The chronological path of images writes a biography of a special kind. It allows to think in sequences just like in a sequence analysis as sociological methodology. Description, reconstruction, analysis, causality remain a challenge in our attempts to learn and understand more about biographies or the construction and reconstruction of life courses. 
Error 444
The error message 444 is a not so rare encounter while surfing on the web. The error code 444 stands for the message that from the side of the server the connection is closed without any additional message. The occurrence leaves you without further indication of what exactly went wrong in building a connection to a web service or website. You just simply get shut out and that’s it. It may be tough on you if concerns your online banking or other access to vital services delivered through the internet.
In organization science and social science there are many new studies dealing with the finding, dealing, coping or handling errors. It has become much more acceptable to deal openly with errors, blunders or failures. From an individual as well as organizational perspective the cultures that deal openly with these events seem to have a certain advantage to overcome the consequences of errors at all or faster than others.
In some biographies failures are part of the lessons learned throughout life. It is deemed important to acknowledge failures or paths not taken for better or worse. Organizations just like individuals seem to learn more intensively from their failures or omissions than from everything seemingly running smoothly. Learning curves are faster also for “machine learning” if you have access to a huge data set which contains ample data on failures rather than encountering failures after release. Hence, the compilation of errors is an important part or early stage of a learning process. Failed today? Fail again tomorrow. You’ll be really strong the days after although it might hurt. 
Force of dependency
Drugs have their particular strength in creating dependency. This is well known for tobacco or alcohol. Helping people to overcome the forces of dependency has its merits. At the same time it is big business. Vaping instead of smoking might be a way out one dependence but into another one. In the end it is an empirical question how many persons can escape the force of dependency of both types. Important to test the probability to get rid of the dependency altogether. With respect to hard, life-threatening drugs like Nitazene the death toll keeps rising in the UK. In the latter case changing the dependency is already a success. The sustainable deflection from drug dependency has to address underlying issues and health hazards. It is a rather individual issue. Society wide evaluation studies need to inform the debate also about placebo effects. The force of dependency might not only be physiological but psychological or linked to the social environment. All these potential effects have to be carefully sorted out before simple pseudo-solutions are implemented. Even the price and availability of drugs is part of the overall equation to solve the force of dependency.
Topography of Terror
The documentation centre “Topography of Terror” in the middle of Berlin is easy to reach. The “Potsdamer Platz” is nearby and so is the “Kulturforum” with its galeries, museums and the “Berliner Philharmonie”. The documentation centre gives easy access to the historical evolution of Nazi-dictatorship from the earl beginnings, the horrific terror spread across Europe and first insights into the prosecution of criminal acts in the immediate post-war period. The Beyond the exhibition with audio-guide there is an easily accessible specialized library for personal or scientific research. The accompanying program of book presentations and discussions (image below) complements the busy show rooms. The external “walk through history” allows to grasp the main proceedings of the terror regime.
For special interest or research questions it is a very useful starting point. Hours in the library have to complement the research. Good to see that so many students walk through the documentation centre not only in groups from the neighbouring schools. The interest to understand when and how the terror started will allow us to better guard against those right-wing extremists who use a lot of techniques of propaganda well known and exposed in this documentation centre of the terror of the Nazi-regime.
