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.
Own Insulin
People who suffer from type 1 diabetes do not produce enough insulin themselves. The World Health organization estimated that „in 2017 there were 9 million people with type 1 diabetes; the majority of them live in high-income countries“ (WHO 2023). The report on successful reprogramming of stem cells of a person to produce insulin again and subsequently transplanting these cells into the same person allowed to produce own insulin again for that same person (Mallapaty, 2024). The hope for millions of people with type 1 diabetes is high that eventually there will be a cure to the disease. Scientists caution that there are no data yet for how long the transplanted own stem cells will produce insulin. Hence, the hope is driving research forward on a promising way forward. The case of type 2 diabetes is very different as additionally the absorption of insulin in the body causes problems. We keep walking and building muscles to facilitate the insulin absorption in the body to guard against the onset of type 2 diabetes. Interaction of diabetes and aging is another topic that needs our attention as rapidly aging societies are at higher risks to face many more people with various forms of diabetes.
Russian Demographics
Dictators prepare their countries long before for upcoming wars. One indicator of such strategies is the pursuit of “natalist” policies. These are demographic policies that aim to increase a country’s population so that the human losses endured during war maybe recovered faster. Russia has had such a policy doctrine in place for quite many years. Only, it didn’t work. Alain Blum and Sergei Zakharov (2023) have shown this in their paper on “L’obsession nataliste de Poutine“. Rather than achieving a growth in the population, at best, the further rather rapid decline of fertility and the population size before the war is reflected in the data (until 2022). The recent objection of youth and women to bear more children is subject of massive opposition of Putin’s forces inside the country. So-called total fertility of 1.5 per woman before the war is as low as or lower than in many other European countries. However, on the other end of aging is mortality or life expectancy. The data show a rather bleak picture of Russia already before the invasion of Ukraine. Based on data published from INED in France Russia has about 1.000.000 more people dying in 2022 than babies born. Bad handling of the Covid-19 pandemic (inefficient vaccines) is also a reason for this dent in population size. Adding outmigration of youth that does not want to stay in a country that goes to war with peaceful neighbors, this bleak population outlook is the disastrous heritage of the Putin years of Russia in the 21st century for generations to come as well. 
Ballistic Missiles
Ballistic missiles have been studied as part of physics for centuries. The basic mechanics in gravitational fields like on earth are well known. Longer reach intercontinental ballistic missiles (ICBM) have been built by several countries for defensive or offensive purposes. China had demonstrated to master the science and technology of rockets since its latest launch of a ICBM in 1980. In 2024-9 China has demonstrated again, it is still capable to launch such missiles with long distance range (Japan Times 2024-9-25). This is both a technological task, but much more a geopolitical issue as a reminder to be taken seriously on the international political arena currently. Technological capabilities and capacities have regained geopolitical strategic importance as attempts to shift the global balance of power, which is undergoing multiple challenges or even changes. Flagging technological options is not only important to demonstrate own military strength, but to present a country as a potential strategic partner of global reach. Window dressing using weapons is much more oriented towards other countries (buyers of weapons mainly) than of relevance for Chinese society. Strategic alliances seek strategic partners. China is likely to receive more attention in the 21st century than before.

Patient Capital
There is something cultural about capital. Different cultures use different narratives when they commonly talk about capital. In Western capitalist societies it is common practice to cite “capital is a fugitive dear”, meaning that people who command sizeable amounts of capital tend to flee places once they become to agitated, especially by politicians. The Eastern narrative surrounding capital is more focused on “patient capital”. The newspaper “China Daily” has more than 6.000 entries referring to this term. On 2024-9-26 (p.9) the Japenese economist Kazuyuki Motohashi praised the Japanese economic system and its specific form of patient capitalism as based on” long-term, stable investment, which enables companies to achieve sustainable growth in the long run”. The Chinese economy suffers as Western capitalism from excessive focus on short-term profit seeking and this causes huge market flucturations shifting quickly from shortages to oversupply and back again. Short-term rent seeking is driving whole industries into fluctuations that are hard to attenuate through other economic (fiscal and monetary) as well as labour market policies (training, re-locations, internal migration).
It is interesting to witness that recently in Germany an example of a bank that had benefited from a patient capital approach of the German government for more than a decade (Commerzbank) is now prone to a bit of a hostile takeover from another bank probably more interested in the short-term rent-seeking. After all, banking and the varieties of capitalism approach highlight that at the very heart of economic rationale there remains a little bit of a cultural twist to understand what is happening in international economics and competition.(Image: Musée Rodin Paris 2024, Le Penseur”)
Fiscal Union
European Integration is slow and hard to come by. For others it is moving too fast (Brexit). Cultural diversity is a real asset of the EU. The economy or the economies are powerful on an international scale. Nevertheless, the diversity concerning the tolerance of fiscal deficits is still widely spread across the Member States of the EU (see image below). Some states seem to play it cool and run relatively high deficits compared to the EU averages. In OECD comparisons most of the above average fiscal deficits are closer to or even below OECD averages over time (link to pdf-file OECD, 2024). Within the EU differences in government expenditure as % of GDP or the indicator of Gross public debt according to the Maastricht Criteria range from 20% to 160% as percentage of GDP. This entails a different level of resilience to future crises. After we managed to leave the previous 3 crises (financial, Covid-19, energy) it is time to prepare for what might come next in terms of challenges. Preparing public deficits to be able to soften economic shocks is essential to be able to sustain yourself and support others. We seem to be a bit off-target to coordinate fiscal deficits across the Union. Eastern and Northern countries have suffienct scope to support expansionist fiscal policies, be it in the realm of a defence union or to address climate change. Southern Europe will find it more difficult to raise additional funds to prepare now for future challenges. Fiscal deficits might even be not only an economic phenomenon, but a cultural one as well. If we compare Japan with a deficit running at 240% with South Korea with 50% Asia is showing even larger diversity in terms of fiscal preparedness.
An economist’s stance on fiscal policy and fiscal union might depend much more on her/his region or country of origin than economists might want to believe.

Traffic Speed
Most people use cars or other automotive vehicles (e-bikes, e-scooter) to get faster from point A to point B. However, speed of traffic causes trouble for other groups of mobile persons. Demands on attention rise, despite the abundant use mobile phones even during driving a car. Mapping systems and services from A to B have become an almost daily exercise. Statistics on road accidents that involved inadequate speed are between 20 and 30 percent of all deadly road accidents, depending on the source of information and country (Example D). Frequently, speed is not the only cause, but other behavioral mistakes occur jointly.
Traffic signs are a basis to make drivers aware of accident prone locations. Too many of them may even lead to the opposite effect of ignoring the signs. Reducing the speed of traffic in inner cities is a steep challenge and many cities invest substantial amounts of money and effort to monitor and try to control better excessive speed. Schools, sports centres and shopping areas are all hot spots of automotive and pedrian encounters. They deserve special attention. Penalizing excessive speed is one way to nudge behavioral change. Although the statistics on the huge amounts of penalties awarded does not seem to alter the behavior of traffic participants in the short run. For some it appears to be a regular part of their budget of mobility with no consequence for behavioral changes.
For years the dangers of inadequate traffic speed in cities made young families and older persons leave more risky inner cities, but adaptations of hot spots and increased control systems seem to work in the long run. The “externality” of inadequate traffic speed is higher costs for the health system and society at large. About time to make a “behavioral turn” in traffic speed. 
freight transport
The transport of goods is an important and crucial economic sector to achieve reductions in CO2 emissions. According to statistics from Eurostat Total Road Freight Transportation increased by an annual 0.6% percent between 2019 and 2023. Considering the slack during the Covid-19 economic restrictions this is a remarkable development. Most people agree that more freight on rail could allow a much better performance concerning CO2 emissions. This needs substantial investments in infrastructure and intelligent solutions for optimised and accessible freight loading points. The logistics of the last mile for delivery has found many innovative solutions with battery-supported e-vehicles. The tough issue seems to be the production of e-lorries at competitive prices to the Diesel-engines. Considering the legal obligations to take breaks to ensure sufficient concentration of lorry drivers, the battery charging infrastructure has to be planned accordingly. Ports and airports a certainly key infrastructure for freight transport as well. Industry has additional key locations with high freight frequencies and tonne-kilometres. Eurostat data show that EU-wide empty running vehicles account for about 22%. Scope for optimization is, therefore, a continuous challenge for the sector.
E-transportation is high on the agenda in the sector and production of e-lorries a big challenge. There a many positive signs that the sector has taken up the challenge as there are an estimated 100.000 € per year cost advantage of battery-driven lorries compared to traditional ones (Le Monde 2024-9-24 p.16). This is simply a long-term survival issue for the sector. Smart transport solutions add to the productivity potential of the sector in combination with electrification. 
Buzzing free
It is always a chance to be in a city that bans cars for some time from streets and bicycles and pedestrians can walk freely in the city. On September 22nd 2024 this is the case in Brussels. In addition, the public transport system allows people to buzz around the city free of charge. Of course this is an invitation to get to know areas of the city where you normally don’t take the time to visit or mix with people. The police used the time to teach children how to cycle in a city in all security and respecting basic rules despite the enthusiasm for speed or going round in circles. Unfortunately, this happens only one Sunday out of 52 in a year. It is just amazing how the feeling of safety on the road changes again. The level of noise and pollution drops to levels of the countryside. Buses and trams pass the city easily and most people get around faster than they do on other days of the year. It is a bit like a coordinated health intervention for the stressed urban survivors. This experience is a modest reminder of how nice it was in Paris during the Olympic Games 2024 when prioritizing mobility beyond cars haa been effectively implemented for several weeks.
Nature Spectrum
When it comes to colors, nature has shown us the way forward for a long time. Before mankind „invented“ bionics, nature had opened up the full spectrum of colors. It took us thousands of years to understand how to recreate the colors of something technically rather simple like the rainbow. The colors continue to impress us independent of our cultural background. More interesting than, maybe the Atomium in Brussels, is the almost daily reproduction of a rainbow in a park in Brussels (park Bois de la Cambre). All it needs is a sunny day, water fountains and the right angle of observation. It is magic, but still simple science. Enjoy.
Sufficient
What do we mean by sufficient? Sufficient of what? French philosophers currently debate the topic under the French notion of sobriété (sobriety). They give as English translation sufficiency, but the notions do not match exactly in the usual understanding of the words. In breaking with the economic rationale of more is always better, the idea of having sufficient food, room to live in or social contacts to not feel lonely, the notion of sufficiency hints towards a rethinking of our customary lifestyles. How many trousers are sufficient? Well, as with shoes there might be gender differences or more generally interpersonal differences or preferences to come to the conclusion of how many is sufficient. If we bring in the notion of sobriety in additional, we allow another social and/or ecological dimension. This may redefine what is sufficient based on judgments how much our planet can handle (emissions) and distributional judgments. The western lifestyle of the last 100 years is no role model for other countries to follow. It is urgent to rethink our growth based economic model to develop new socially viable ways of production and consumption. It seems to be a necessary condition to reconsider the notion of wellbeing and wealth from a sufficiency perspective. It is a sobering thought, isn‘t it?
Wave Length
The links between art and science are manifold and run in both directions. Artists challenge science or the outcomes of science and scientist refer to or maybe inspired by the work of artists. If artists challenge scientists by proposing an alternative theory they become subject to empirical scrunity like the unfortunate fate of the theory of colors of J.W. Goethe. The physics of colors has long been established and the theory of colors and light are best represented in science using wave lengths as the unit of measuring different colors. Hence, in this theory of colors or light the spectrum of colors runs from violet, dark blue, indigo (short wave lengths) passing yellow (medium wave length) to orange and red (longest wave lengths).
The painter Ellsworth Kelly has also challenged the science-based view of colors in “Spectrum IX” from 2014 currently part of the exhibition “Ellsworth Kelly. Formes et couleurs, 1949-2015” at the Fondation Louis Vuitton in Paris (extract of image below). As a provocation to the scientifically trained vision Spectrum IX breaks up the running from short to long wave length to take the scientific linear colors of the spectrum and split the spectrum in the middle (yellow) and join the ends upside down. Alternatively, take the spectrum and glue both ends of the color spectrum together to a circle and cut in the middle of yellow to form again a seemingly linear evolution of colors.
Now, let’s meditate in front of this new spectrum of colors and follow your senses. The challenge of the theory of colors is a provocative statement of all those imaginative potentials we exclude through a solely science-based view of colors. Art opens up virtual space and fills it sometimes with abstract reflections on colors. It is raising the question of beauty versus science, beauty in science or beauty through science. (Image: Ellsworth Kelly. Spectrum IX in exhibition Formes et couleurs, 1949-2015″)
Phase Shifting
The Berlin “Hamburger Bahnhof Nationalgalerie der Gegenwart” recently acquired “Phase Shifting Index” by Jeremy Shaw. As part of an exhibition of new acquisitions, Sam Bardaouil, the director of the museum and curator of this exhibition has installed the large-scale video and sound installation at the end of the long corridor of the “Rieckhallen”. The impressive, even overwhelming art work was created in 2020. It was first shown at the Centre Pompidou in Paris. 
The piece consists of seven large suspended screensand creates a space like in dance club, discotheque or dance studio. The visual and sound experience is allmost psychedelic. The near obsessional dancing shown on the screens represent different periods of dancing with their particular patterns of movements and choreographies. The phase of the electromagnetic waves is shifting from one screen to the other and towards the end of the performances it becomes clear, that they all follow a similar wave or rave pattern. Sublimation or ecstasy are the underlying index-like common traits. Each period or decade 50s, 60s, 70s, 80s, 90s, all had their peculiar dance and movement patterns. The video-installation is like a history of art of expression through body movement, amplified and indexed through rhythm and sound.
Electromagnetic waves can be characterized through wave shifting in various forms. This work gives us a feeling for the fascination of movement and phase shifting emotions. Don’t worry, the immersion ends after 10+ minutes and, if you like, you might read up on the physics of electromagnetic waves and phase shifting to calm you down.

Scorched earth
The Russian military strategy in Ukraine is yet another example of scorched earth. Upon retreat the space is left in a devastated state. Worst of all are the land mines that kill or mutilate even after the immediate danger has passed. The logic in the Russian aggression in Ukraine is particularly strange as the Russians were arguing this is their land and claim the people living there were mostly Russians. The retreat of Russian troops eventually will leave huge territories scorched. The destruction of energy infrastructure is also clearly targeting the population at large to make entire regions difficult to live or survive in during the approaching cold winter months. Decentralized energy provision rather than huge power plants have become a survival strategy for Ukraine and probably its neighboring countries. Sensitivity to the dangers of scorched earth is important to get priorities right for relief.
Artists sometimes show us the way ahead with bright colors, if only we were able to see or understand the signs or signals. (Image extract from Mark Bradford “Scorched Earth”, SMB Berlin, National Gallerie der Gegenwart im Hamburger Bahnhof, 2024-9)
Ukraine Chess
Strategies in Chess, sometimes, inform strategic behavior in wars. In chess there are clear definitions of 2 opponents and their material. Modern warfare has blurred both elements. Opposing parties build alliances and the material allowed or available is hotly debated as well. The war of Russia on Ukraine territory, nevertheless, resembles a variant of a chess game considering the different stages of the game. All starts with Russia choosing its opening attacks. A rather aggressive version of the opening is the King’s Gambit in which a fast attack tries to overwhelm the opponent. Ukraine, because of the surprise and lack of immediate support from neighboring countries, chose a careful defense trying to hold the lines amid a fast forward moving assault. A further restriction for Ukraine was to not use weapons from supporters on Russian territory. In chess this would mean your defense is not allowed to cross the middle line of the chessboard. For example the so-called Sicilian defense does exactly this for many moves of the opening. However, in the middle game this changes and the defense might prepare forceful attacks based on a solid defense. With 2 and 1/2 years into the war the opening has played out and we see middle game strategies take the upper hand. In chess this consist in attempts to gain material advantage, possession of strategically important positions and psychological stamina to mention a few. The middle game can drag out for a long time, especially if a balance of power persists. Even in an unbalanced situation peacemaking takes time as well. In any case, during the opening phase the “Sicilian” defense can handle a defense that is restricted to “own half” of the chessboard, but in the middle phase such a restriction is an even more severe impediment. Relaxing this imposed restriction by supporters opens up additional possibilities for the defense as well as counter strikes. (Image: Shredder Chess App White opens with Kings Gambit and Black answers with Sicilian defense)
Walking Danger
Autumn brings color into nature. This is for some the bright side of life. However, the sun sets much earlier every day and many people begin to walk to school or work and back during the dark time of the day. Unfortunately, this entails an additional danger to those walking the cities as bad light conditions cause many accidents of pedestrians. The statistics provided by Destatis (2024) for Germany show a marked increase of walking accidents from September onwards and lasting throughout winter. Equip yourself with bright colors and reflectors to avoid being a walker in danger or a walking danger. On Sunday it is pretty safe to go for a stroll. City life is less stressful and professionals in a hurry usually take a rest on that day. The conclusion is to choose your track wisely in order to feel safe on weekdays.
Innovation Painting
Innovations have fascinated painters just as much as photographers. The impressionists have painted trains and steel bridges as well as modern city life. Innovations change the atmosphere of a situation and new forms of transportation have been admired for many decades. Artists and painters have dealt with this phenomenon in various ways. Either the innovations have puzzled the normal vision of people or things or the artists hinted at curiosities or incompatibilities. Gustave Courbet has depicted in a unique style (Realism), as early as 1865, a seated woman with a paddle on something similar to a catamaran. It is maybe surprising that the modern form of stand-up paddling looks a little bit like the „podoscaphe“ painted by Courbet. Innovations in sports continue to evolve and become part of Olympic Games as well. Some disciplines make it into the Olympic canon rapidly, others never make it. The exhibition of „Artists and Sport“ gave ample opportunities to reflect on the the relationship of artists and innovations as well. (Image Musée Marmottan Monet, Paris 2024, Extrait de Gustave Courbet, Femme au Podoscaphe. 1865)
Waiting time
A new report by Darzi, a former cancer surgeon and past minister of health in the UK, paints a dismal picture of the British health service (NHS) over the last 15 years under conservative rule. The public service has seen no increase in its budget accounting for population growth and the aging of the population. The service is no longer able “to give patients the timely care they need” (The Guardian 2024-9-12 title page). Increased waiting times lead to an estimated 14.000 premature deaths per year. Darzi presents data that show 300.000 persons had to wait longer than one year for a treatment that should have been performed within 18 weeks.
The staff seems desperate for changes as well as they have to spend more time on management of waiting times, time which is lost for real treatment. The quality of care is another issue which awaits urgent attention. Health cannot wait for most patients, but the neglect of investment in hospitals and people is expensive in the longer run. Even the reform efforts should not wait any longer. Time is a precious good and each life matters. (Image back cover of exhibition catalogue Käthe Kollwitz at MOMA 2024).
International Geometry
Geometric forms sometimes serve to make international affairs more transparent or descriptive. The Weimar triangle is such a formula, which helps to show the links between states. In the journal “Le Monde” of 2024-9-13 an interview with Radoslaw Sikorski reflects the shifting side lengths and military weights within this triangle. The Polish Minister of foreign affairs points at the threats from Russia to violate the air space of Poland and the legitimacy of Poland and the Ukraine, of course, to defend its air space and territorial sovereignty. The guarantee of international law, however, is heavily dependent upon adequate international geometry beyond the Weimar triangle. The meeting with a representative of the Pentagon (US) enlarges the scope of the triangle.
Talking about the reach of missiles in defense is yet another exercise in geometry as this depends on starting and supposed, or reachable, end points. The use of GPS-signals in civilian and military applications is another example of how geometry is ruling our modern lives. Let’s embrace it, rather than shun away from the geometry behind it. (Image Exhibition room at Wiels Art Centre, Brussels 2023).
Health GDP
A report by the WHO and the World Bank (2023) on universal health coverage and financial hardship has emphasized the difficulties to reach the goals defined by the strategic development goals (SDGs) by 2030 in this policy field. Moreover, the paper by Mazzucato and Ghebreyesus (2024) invites us to reconsider the importance of health in the overall assessment of development and progress. The authors ask us to “rethink the narrow focus on growth in gross domestic product (GDP) that typically dominates economic decision making”. There is of course a long debate on the status of health, GDP or wellbeing as major policy issues or even foundations of the a state’s major objective. For economists the question has been answered for decades to favor GDP growth and more or less the other objectives can be achieved with a time delay. Recently social scientists have highlighted the overall importance of wellbeing or happiness rather than GDP as stated in some constitutions. Health as an overall objective is another challenge to the existing economic framing of societies. In a traditional economic perspective the health sector is part of the GDP increasing public and private sector of the economy with insurers, equipment and persons contributing to it. On the other hand, health enters into the distribution or consumption part of the economy. Each country strikes its own balance between production and consumption. Put simply, in form of an equation where production equals consumption, health enters on both sides of the equation in each country. On the global, scale the distribution between costs and benefits of health have not narrowed over the past. The challenge for the world population remains steep. Considering unequal population growth across continents, the situation might get worse before it hopefully gets better. We still have to continue huge efforts to increase overall health on earth for example through large scale vaccination programs. (Image The tombstone of Molière in Paris 2024)
Desertification
Since 2018 we have evidence of the progression of desertification into some Member States of the European Union. The mediterranean countries are concerned as well as regions of Bulgaria and Romania near the Black Sea. There are multiple sources of desertification. The 3 main reasons of desertification are soil erosion, loss of soil fertility and loss of natural and desirable vegetation besides wind or water erosion and salinization. We also know that man-made climate change is at the root of the past and recent problems. The statistical indicators of land degradation are collected by the European Joint Research Centre and these data show a dismal picture of land degradation in general and desertification as part of this process. A study by Ilea et al. published in Nature 2024 projects an intensification of extreme weather in the coming years. Higher temperatures will most likely enhance desertification and more frequent flooding will contribute to more soil erosion as well. It is a rather strange process that we know we are creating severe problems for some regions which endanger the roots of their existence and yet we do not act upon those undeniable facts (United Nations SDGs list). The amount and dynamics of land deterioration put the global South under severe pressure, but also the wealthy parts of the Mediterranean basin will be affected. It about time to acknowledge that we are all part of the global changes and challenges. (Image palm tree in Paris, Jardin du Luxembourg, 2024)
Heat Stress
Heat causes cardiovascular and pulmonary stress. This has been well-known for a long time. A newly published epidemiological study for Germany reiterates this finding and adds more details to the picture of who is affected most by heat stress and heat-related mortality. Old age and being female increase the heat-related deaths in Germany according to the study by Zhang et al. (2024) published in the Lancet Regional Health. Our body’s thermoregular responses to heat stress like vasodilation or hyperventilation cause additional stress to our cardiovascular and pulmonary system. Excessive sweating and dehydration, possibly increased through medication, amplify heat-related risks. The study corrects the estimates by using fine particulate matter (PM2.5), ozone (O3), and nitrogen dioxide (NO2) data on the district level in the analysis. High concentrations of PM2.5 and NO2 increase heat stress and related deaths as well. Inner cities are, therefore, not the best place to be during the hot season. Most southern European inhabitants of big cities are aware of these health hazards and act accordingly. In Germany it is much less a habit to quit inner cities during the hot days in summer, but climate change will make this a major concern. Greening inner cities is an urgent necessity, which is not just nice to have, but saves lives. (Image Berlin Bears, Berlin City Center 2023)
Games over
All nice things eventually come to an end. So do the Paris 2024 Olympics and Paralympics.
The images have been impressive of both events and the millions of spectators give a good testimony in this respect. The cultural by-program of the Games was equally remarkable. The live performances of dancers not only on the opening and closing ceremonies attracted big audiences. Many well-known sites of Paris prepared their own events and inspired as well as entertained the visitors.
On the small stage in front of the “Marie de Paris”, the city hall (Image below), ballet performances (video) were staged to hint at the possibility to see more artistic performances throughout the year in Paris opera houses and other stages.
Showcasing many forms of cultural, inspiring and entertaining events gave a valuable additional flavour to the Paris Olympics. Many good reasons to come back and renew unique moments in Paris beyond 2024. Paris hotels will be more accessible again for moderate budgets and waiting times for entries should come down to normal levels as well. Back to a new normal for Paris. Well, maybe. The millions of spectators who followed the Games on television and social media might eventually decide to rank Paris higher in the “cities you have to go to at least once in your lifetime”.
Painter Sociologist
In going to a gallery and exhibition of paintings from the 17th century (Gemäldegalerie Berlin) you do not really expect to attend a class of sociology. However, this is exactly what the Flemish painter Frans Hals does with his paintings of various genres of society of his time. His sociological categories are for example unmarried young persons, married couples or pensioners living in a shared home. Other social categories of interest to him are a caregiver or, more common for the time, persons from noble or wealthy families. His painting „The Regents of the old men’s Almshouse” (ca 1660), the male pensioners home is one of his last paintings when he himself was already about 80 years old. Similar to a College of students the elderly home was run by a house father and house mother who took care of the daily living. The paintings of Frans Hals covered the entire life course with a cross-section perspective of society at his time. From few of his supporters he painted even several images moving towards a kind of longitudinal perspective on a person’s life course. Certainly, with “Oude-mannenhuis” (image below) he was interested not only in individual life courses, but of the conditions, forms or images of aging at his time. He probably was one of the first to challenge the negative stereotypes of aging.
Theatre Archives
The process of creation in the realm of theatre performances has manifold facets. The French National Library (BNF) in Paris has received the archives of the „Théâtre du Rond-Point” in 2023 and honors the donation with a fascinating exhibition on the immense creativity of the author, scenarist and director Jean-Michel Ribes. (Image below) The professional diaries of Jean-Michel Ribes and the documentation through photographs from the performances and video extracts allow an intimate view into the hard work of producing theatrical performances, popular television shows and comedies. Jean-Michel Ribes took notes of all sorts and kept extensive lists of potential collaborators, actors, daily occurrences and just nice sounding phrases. From just a simple phrase heard on the streets he developed a small piece to be performed in shows. Listening to the people and enriching this with great actors in superb scenery made his popular success. The creativity seems to derive from ample note taking and coming back to them eventually.
Lost Objects
Project yourself into the future more than a hundred years from today, maybe even more than a thousand years from today. Some archaeologists will work on the planet earth to uncover the story behind the disappearance of the once very advanced species of homo erectus. They start drilling near some of the mystical sites of this civilization, the cities where mass celebrations were held called Olympic Games. These archaeologists use huge drilling machines to take samples at previous Olympic sites and uncover the remains of the thought to be modern civilizations on earth. Amongst all these samples they find all sorts of artifacts and layers left over. Plastics and metal structures appear in the samples as well as other forms of „artificializations“, transformations of earth’s principal „natural“ raw materials. The inhabitants of earth apparently lost or destroyed the planet‘s capabilities of CO2 storage and eventually became extinct. After fighting for survival on another planet the archeological expedition on earth saved this block of the remains of a doomed civilization. All this is pure science fiction, yet the specimen sample is exposed on the roof of the futuristic Fondation Louis Vuitton building near the Jardin d‘Acclimatation in Neuilly sur Seine.

Olympic Criticism
The Olympic Games are, like every international organization, subject to criticism. In democracies this is part of the DNA of democracies that you can voice your criticisms openly without being threatened by persecution or arrest. The Olympic Games have since its beginning in ancient or modern times favored sport disciplines that have a link to warfare. The spectrum of disciplines has been extended recently to blur a bit this belligerent image of the Games. However even the break dance is performed in a kind of battle or competition between two adversaries. This is the reason why totalitarian states have (had) a predilection to show off their state sponsored warriors in the Olympic Games. Nazi Germany and the Berlin 1936 Games were the worst example of how the Games can get abused only to demonstrate a country’s force through athletes. Dictatorships of our times are not much different in this regard. Showing how many successful athletes (soldiers) you are able to produce is somehow an indicator of your professional training system of elite performance. Now, add to it the top performance in the Paralympic Games like Paris 2024 and you can even demonstrate how well you are able to care for and train potentially even also for mutilated warriors. Criticism of preparations of warriors and war masked through sport competitions are maybe unfair or utterly displaced here. It is, nevertheless, much better to compete on the sports-field rather than with loaded weapons. Only in retrospect, we often understand, why some nations made such enormous efforts to demonstrate a commitment to win as much as possible. With a growing enthusiasm for the Olympic Games the critical reflections rise as well.
Paralympic Counting
The classification system of the Paralympic disciplines is well worked out. This ensures that competitions are on a more equal footing. The counting of medals, points and penalties is an easy task. It is more difficult to keep track of equipment and infrastructure and the adaptation status of it to Paralympic needs in a country or region. Statistics and monitoring of installations is one important step in preparing for participation and success in Paralympic disciplines. On an European open data platform we find the regional data set of “Parasportive equipment in clubs and committees of the Pays de la Loire”, for example. Transparency of structures is a first step in improving access to it. For Paralympic athletes it is the same process to gain access to sport equipment as for all other athletes. The monitoring of infrastructure and equipment is a laborious task, but the documentation of helps people on their way to obtain access. Paralympic counting, therefore, is much more than counting medals and trophies even if they are really nice looking.
Olympic Medals
The distribution of Olympic medals across continents reveals the persistent inequality of rewards across the globe. The first African country in the overall ranking of countries by Olympic medals is Kenya on 17th place. All 11 medals including 4 gold medals were obtained in athletics and in running disciplines 800m and more. The financial resources needed to practice running as high level sport are probably the lowest one of all disciplines. Ethiopia is another African country with this tradition of high level long distance runners on the African continent. Equipment and coaching in other disciplines than athletics involves more infrastructure and becomes more costly and the possibility to reserve infrastructure for elite athletes of a country is more difficult if the infrastructure for the population at large is rather limited compared to the population size. Therefore, the Olympic tradition has to confront the challenge of unequal access to many disciplines of the Olympic Games also in Paris 2024. Being a very good athlete is just not enough if you lack the coaches, training and facilities to be able to compete with the well-equipped countries. The knowledge about the best details of a specific technique or optimization potentials are part of the Olympic challenges as well. The Americas, Europe and Asia might be confronted with new forms or another criticism of imperialist strategies, this time in the domain of sport. The winner or medalists take all. Country rankings appear a bit like the football device “money buys goals”. (Image, Fondation Louis Vuitton, Paris, Extrait of Omar Victor Diop “Diaspora” 2014-2015).
