Time simultaneously

The simultaneous experience of time forms part of the basic understanding of what society is about. However, the participants of a simultaneous game of chess might arrive at a different perspective on time. At the same time when time advances for say 20 chess players, the one person facing the 20 players is advancing on 20 processes simultaneously, but also on a single time measure shared by all. The different processes, or chess clocks, all run in the same timeframe. The experiences of time will be rather different as the simultaneous games usually stop at very different times. Each player has to live up to her own competence, only the one simultaneous player lives in multiple games or time simultaneously. The experience, even on a much smaller scale to handle just 3 parallel processes is a challenge for us. The fascination of juggling might convey a similar experience just on a more physical level.

Time in Chess

The more you advance in playing chess, the more time and timing becomes an issue. Sooner or later you will want to have your very own chess clock to be in control of time when playing chess. It will be difficult to keep your mind hooked on the chessboard rather than the clock as each move is linked to a point in time as well as a duration.
It was common practice for advanced players to note, not only the moves they played, but also the time they needed to play the next move. This helped to analyse the quality of your game. In specific openings of a game of chess you even keep track of “time advantages” in bringing more of your pieces into powerful positions or a “developed” position on the chessboard.
You may choose to play a “Blitz” game, which allows only 5 minutes per player to think about the next move overall, which may turn into a fast hitting battle in an protracted endgame for each side. In anticipation of this you way your time very carefully right from the beginning of the game. In short, you will never consider time as a mere second by second running of time as time has a different weight depending of the progress of the game.
Come on, it is just a game of chess, isn’t it?

Timely timeless

It is very timely to discuss timelessness. Some inventions or artwork appear to have a timeless value. The creation of books has this feature as we have known also a lot about the conservation and restoration of books across centuries. Timelessness is about an open-ended vision of time. In mathematics it is a usual part of the differential equations‘ calculus to handle infinity as an operationalisation or a form of a projection of time into timelessness. Humans have made considerable efforts to create material and, most of all, immaterial goods which try to exist independently from time. Geek or Roman philosophy are with us for more than 2000 years and we still benefit from returning to this original concepts. Egyptian culture and the wall paintings in caves still speak to us, thousands of years afterwards. Each clock suggests that time is advancing, but some treasures achieve the level of a timeless beauty, art or conceptual masterpiece. The more we talk about time, the more we shall cherish timelessness. (Image: Neue Nationalgalerie, Berlin 2026-1, The clock screening)

Time and music

The trick about music is the sheer unlimited variety it allows to experience time. We all think primarily of rhythm as the direct link between time and music. Then there are the additional annotations of composers on their scores like “lento” or “presto”. In addition each note has a frequency as swinging per second, which serves as the basis for synchronization of an orchestra. The length of each note or a each phrase of music evokes specific emotions in listeners. Human embryos even register music as the frequencies and duration travel across boundaries. The relationship of time and music is such a vast subject matter that the scope of this deserves to be studied across centuries, music periods as well as across cultures. Certainly, we find a few books on the subject beyond the simple physics of waves lengths and frequencies.

Time reference

Times serves as a point of reference. We often refer to precise points in time, like dates 1st of May Labour Day, or a specific hour as a reference point. If we talk about 5 minutes before 12 o’clock, we convey a kind of urgency – before it is, presumably – too late. In the arts, particularly poetry, prose or drama, and even beyond the romantic period, the reference to seasons as “emotionally loaded” terms is widely used. Subsequently, there are many compositions in music, which make use of such references as programmatic titles. Through the reference to a specific duration, the scene appears to be set and the reader or listener prepared for a less surprising experience. You might even go full circle like in Vivaldi’s composition of “The 4 seasons”.
The writer, poet and Shakespeare translator Thomas Brasch (Link to publications) has written the poem “Der schöne 27. September” (1980) with an exact reference to a point in time, but reporting in 10 lines, what he didn’t do on that date (own translation).
“I didn’t read a newspaper.
…
I didn’t write a single line of text.
I didn’t set something in motion.”
(Extract from Thomas Brasch poem see above;

Multiple clocks

There is nothing more confusing that multiple clocks that are ticking away without being synchronized, which means, they ought to show the same time. A medical and social science perspective on multiple clocks, however, builds on the fact the different social processes run with different speed, i.e. multiple clocks are ticking in parallel but one may be more advanced than the other. The study of longevity has recently acknowledged that each human organ is aging at its own speed and if the time to failure is close for the liver, the time until problems of your heart might still be far off. Overall longevity is determined by the time to failure of a major organ, despite the fact that multiple clocks of organs are running in parallel.
The can be observed for social processes where, for example, the timing of unemployment or retirement might be dependent on a parallel process of a household dissolution causing a peak in stress. Overall life satisfaction, therefore, depends largely on multiple clocks that might be running in a synchronized or not-synchronized manner. Hence, we all live with multiple clocks ticking inside us and around us. The illusion is, to believe that time is just a single, unique measure.

Time as surprise

Sometimes, time comes as surprise. Time seems to run faster as we perceive it, or time might pass more slowly in actual terms than we perceive or think it does. What makes the difference? There is the objective measure of time with various types of clocks and watches versus the subjective or perceived lapse of time. The discrepancy between the two constitutes an interesting case for further study. Marketing strategies will try to make us believe that a specific kind of product will shorten or lengthen the difference between objective and subjective time. The entertainment industry works very hard on our perception of time relative to one or the other form of entertainment. The best result seems to be that objective time has been much longer than perceived time so that we “lost” our reference to time while being entertained. The so-called social media interaction is rather successful in this form of entertainment, infotainment or edutainment. The moments in life when time comes as a surprise might be great ones in our lives. Particular deviations between objective and subjective time make strong impressions on our memories, too.

Time and Emotions

In psychology, time and emotions are a matter of milli- or even nanoseconds. Showing emotions, intrinsic ones or controlled ones is passing rapidly through our brain and, for example, facial muscles. Hence, time plays a role in how we react emotionally to an image or any event. The author Rüdiger Safranski starts his history of the concept of time with the emotional experience that time appears lengthy or tedious. In his view the emotional understanding of the concept of time is key to a better grasp of the philosophical roots of the concept of time. Starting with Greek philosophers, the Stoic tradition, Augustinus, the history of ideas is full of reflections on time, what it does to us, and how we best deal with the effects time has on us. In famous literature from Marcel Proust or Samuel Becket, we were reminded of the creative power of lengthy periods of time and the importance or futility to ask fundamental questions about time and our destiny. Beyond the rational thinking about time, the emotional experience of time makes up much of the spice of life.

Time and money

In the English-speaking world, most people will be familiar with the expression “time is money”. In times of working for money as pay, rather than growing your own crops, we calculate hourly, monthly or yearly salaries. Time is a habitual point of reference in production systems and calculations of economic growth. Inflation and depreciation speak to value over time, just as investment and returns accrue over time. For comparisons of different investments the chosen horizon becomes a decisive factor. Of course, in the long run we are all dead, but in the meantime time matters a lot, doesn’t it? Take out a loan and you realize how much time will matter, suddenly. Now, let’s turn around the causality, Money is time or can be buy time with money? For many processes this seems to be the case. With money you can buy time off working, or pay somebody to do work instead of doing the work yourself. You can “win time” or gain more free time this way. However, towards the end of your life, money might no longer suffice to buy you time before death even with lots of disposable income or cash. From a philosophy of science perspective, we might even question the concept of time-linked causality altogether. The relationship between time and money gets even more interesting if. we take intergenerational considerations into account like inheritance and environmental heritage. … and “the times are a changing”.

Social time

What does the „social“ have to do with time. Well, time is a perfect case of a social construction or a fundamentally social construct. The definition of time as „Greenwich mean time“ is nothing but a useful socio-political statement to synchronize time across the world, or previously an imperium. Points in time, as shown on a clock(s), can be helpful to synchronize human behavior. We might want to show up on the same point in time to start or end work. Of course there are thousands of ways in which such synchronization might go awfully wrong. This makes for splendid drama and movies have a long history to capture our attention on this matter. Social expectations, a social, psychological, and even a biological concept in extreme cases (Pavlov effect) make many of us to get a bit itchy, if time is getting short to meet other persons or an expected event is going to happen. A lot of social pressure is transmitted through the ticking away of time. The mechanism to internalize social patterns (for example prayer), via time and the clock, is quite powerful and has been used in movies throughout the history of the cinema. Even the individual endpoint in time is in almost all cases a shared social experience and turns into a kind of socially relevant time. (Take your time to watch The Clock by Christian Marclay).

Time – The Clock

Time keeps puzzling us. The 24 hours of concatenated clips from well-known cinema films are a bit overwhelming or even lengthy. However, this spurs lots of time to reflect on time, on a kind of meta level. We see the clock or clocks ticking in all sorts of situations and environments. Nearly all emotional states can be interpreted relative to a time stamp provided by a clock. Christian Marclay’s oeuvre is screened at the Neue Nationalgalerie in Berlin at a time when we feel multiple clocks ticking at the same time. For the sociologist, there is time on the macro-societal level, like overall socioeconomic development, but also individual time. A single person or a single moment in time may have very different macro-social implications. The possibility to live through the cineastic interpretations of ten to, as opposed to, ten past the hour, are interpreted by us with very different meanings. In a longer or historical sense, the timing of time does not matter that much. Point in time or time as duration, that is the question. Art in cinema can play with this like rock around The Clock. Don’t ask me how much time I spent watching, thinking and feeling through time in this movie exhibition, Should we always measure time with a clock.  Want it or not, we measured by our smartphones all the time and on multiple timelines.

Telework Challenge

There is a seminal trend that many employees prefer to have a choice to work on the premises of the employer or remote from home. This flexibility has become a major element of collective bargaining on work and time in larger companies in order to clarify rights and obligations.
In France it is about 1 in 5 of employees who do telework one day per month (1 in 6 in Nouvelle Aquitaine). The higher up in the hierarchy a person is, the more likely s/he is to do telework. Higher levels of educational attainment and seniority in a company also improve the access to and use of telework. There are still many employees who would like to do telework in their jobs, which technically could be done remotely, but who cannot do it (1 in 3). Most of those are denied the possibility by their employers.
Data from a survey in Germany from 2014 showed that before Covid-19 men were worked more often remotely than did women (Lott & Abendroth, 2019). The latest figures from France 2024 show that women have overtaken men as remote workers (Askenazy et al. 2025). As working from home has become more a part of the “standard employment relationship” today, the fears of loosing out on career opportunities due working from home seems to play less of a role nowadays, probably for both gender. Compared to 2014 the costs of equipment and availability and ease of installation of fast internet have become more affordable and might push the spread of telework even further.
The data from France show a strong positive correlation of remote work and commuting distance to work. Hence, long commuting distances “drive” more people into telework, which makes a lot of ecological sense, too.

Marc Aurel Book 8-9

In book 7 paragraph 38 the stoic wisdom is exemplified in the the the short phrase „If you have sharp sight, use it: but, as the poet says, add wise judgment“. Being sharp in your reasoning or data collection is only part of the human endeavor. A wise judgement is, however, an ambitious aim as judgments have different short term and long term consequences. Intergenerational considerations as for climate change ask for respect of other species, biodiversity and to take into account very long time horizons.  The quote from book 8 paragraph 5 appears very modern or post-modern in this context. „There can often be wrongs of omission as well as commission.“ (both citations from Penguin Classics edition) Not acting on behalf of future generations and disappearing species is the most crying omission of our time.

Vacation or Workation

Vacation or Workation, that is the question. Remote work and outsourcing of work have  created the opportunity for more people to work from distant places. Logging into the firm’s or the administration’s secured intranet enabled to work from where you prefer to work rather than on the premises of the firm. After the technological shift to enable secure remote work, the acceptability of remote work is a societal issue. Whereas bosses worked or had to work while on travel for many decades, the same has become feasible due to reduced costs for many other employees as well. The Covid-19 pandemic has forced another shift in the need to accept and advance remote work as well. Taken together the option of a “workation” instead of a vacation became equally more feasible. The borderline between remote work, “workation” and vacation has become more and more blurred. It remains to be seen, whether these options enhance an outsourcing trend by firms or whether  more “back-sourcing” or “in-sourcing” will be the consequence.
Employers with their associations and employees with their trade union representatives have a need to include such topics in their bargaining agenda in addition to pay, health and safety, as well as working time adaptations.

Vacation time

According to statistics from INSEE about 20% of the French population reported in 2024 that they could not not go on vacation due to financial reasons. Another additional 20% did not go on vacation for other reasons based on another survey mentioning other reasons, like psychological or logistical issues as being of overriding importance.
Openness to new experiences is a well researched concept of psychology and vacations can be a challenging time for established convictions. Meeting people from other cultures particularly allows to reflect on one’s own values and behavior. Some people may just want to avoid being challenged or even potentially destabilized. Destination time and place involve choices and decision making often within families or with friends.
The topic of vacation is much like an evolutionary process. Towards the end or some time after the vacation time, there is” evaluation time” and the preparation of the next experience.

Fontainebleau time

In the Chateau Fontainebleau time seems to pass with a different speed compared to the busy times in Paris. Taking a stroll at the park, boating or horseback riding along the endless paths contributes to the perception of wide, open space and a different space-time experience. The measurement of time shown on a fine craftsmanship of a clock in the castle highlights the fact that there is more to time than just seconds and minutes. The hunch of the time that there is maybe a cosmic time beyond our calendar is a precursor of later scientific discoveries. Time in the early 19th century of Napoleon’s reign had just been restored from calendar of the French revolution. Whether time is counted as 2×12 hours or in 24 hours was also a matter of politics rather than rational decision making. The impressive clock in the Chateau Fontainebleau shows ambitious as much as awareness of defining and counting time, just like an absolute ruler might conceive it.

Work time reduction

One of the major elements of social progress in the 20th century consisted in the reduction of work time. Reductions from 48 hours per week in the first half of the century were largely reduced to 40 hours per week or less in some industries with strong trade union representation. State regulations also pushed in this direction with positive implications for physical and mental health as well as wellbeing. Advances in longevity of employees may be attributable to this social progress agenda of the 20th century. In the 21st century we witness a new thrust of enterprises and employees striving to implement a 4 day work schedule by at the same time organizing a further reduction of work hours. The scientific evidence which is based on pre- and post trial assessments of workers satisfaction shows rather positive results (Fan, Schor, Kelly, Gu 2025). More studies are due to accompany this potential of further health and wellbeing effects of reduced work time and the reorganization of work time in enterprises.

Work and Time

The link between work and time has been evolving as a major element of social progress over centuries. In what younger generations seem to take for granted, <40 hours week, paid time off-work. 4-5 days per week to name only the major ones, has been the result of huge struggles and hustles driven by employees and their trade unions to achieve such milestones. The current debate to get employees back into offices and/or to work longer hours again, is also in the end a debate about work and time. The advantage of working from home consists among other factors in saving a lot of valuable time and stress from commute to work. This unaccounted time to go to work has become a major health hazard even in an apparently comfortable company subsidized car or any other means of transportation. The traffic jams of so-called rush hours, when in fact everybody is slowed down, are a serious health hazard usually ignored by employers. However, these hours are a major part of the work-life-time balance of employees. In many negotiations and collective bargaining about working time this is the big elephant in the room rarely addressed.

AI Workday

Our workdays have seen considerable changes throughout the last few days. The home office boom has allowed employees to work for extended hours from home. The there is an abundant literature on the effects of home office work on well-being or the work-life balance. Productivity gains could be reaped by employers and a better work-life balance was a lasting advantage for employees.
The increased use of AI specific to some occupations has introduced a new form of added  productivity for some occupations or professions, AI as complementarity, whereas other occupations suffered a higher risk of being substituted by AI applications.
Based on time diary data, the study by Wei Jiang et al. (2025) reports that users of AI have longer work time and reduced leisure time. Competitive labor markets increase the pressure to put in even higher hours of work. Nerds, just like workaholics, are likely to be drawn into excessive hours of work with increased health risks. Enterprises and consumers appear to be gaining more than the employees, who are at a higher risk of loosing out on their work-life balance over time.

Wave and Particle

The history of ideas in physics has been evolving or revolving a lot around the wave-particle-duality. Even if the basic debate by now is about a century old, we still need to come to grips with this challenging notion that light is not just a beam and nice colors through a prism yielding a spectrum of frequencies, but it can emit material matter called photons that have a non-zero value(s) of energy.
Max Planck came up with the formula E = h × f, where h is the Planck constant, E the energy and f the frequency of the photon. The synthesis of Einstein’s light quanta and De Broglie’s matter waves became the foundation of quantum mechanics.
The exciting evolution of physical ideas results in the state of the “art” view that, for example, light can take both forms, wave and particle, at the same time. Quantum mechanics has become a thriving field in physics and is currently transforming the world of computing in the 21st century. The amounts of funds invested in the race of applications of quantum computing across the globe are “astronomic” and have become part of dual-use spending of research funding. Encryption of information or access codes are of growing importance for civil (banking, mobility, health info) or military purposes. The speed of quantum processors will allow cracking of codes much faster and therefore new dangers are looming in many fields. It is a rather competitive field, which has evolved a lot from the original wave and/or particle vision of the world (of physics).
For social scientists there are several examples of applications of the concepts of quantum mechanics to social and behavioral sciences (Link 1, Link 2). Hard to predict, whether the wave and/or particle view will dominate the social applications of elements of the history of ideas in physics. New concepts in science challenge our traditional science-based thinking about time, space and space-time with implications even for our understanding of causality and covariance.

Negative time

In 2025 an experimental setting has come up with a demonstration of negative time. This is a mind-blowing mental exercise to imagine the science fiction like framework to allow time to be negative as well.
This invites several epistemological questions as well. Can we imagine or live with a reversible concept of time? Maybe music has given us clues. In composition of music, we can easily play the notes of a basic theme just in reverse or mirrored order. Modern rhythms like in beat music as accompaniment by a drum use for example a rhythm like (use your hands or drum sticks!)
“left left right left /
right right left right”, (redo faster if you internalized the rhythm).
A reversal of the beat (its inversion) like replays of rhythms in reverse order seem to return the energy. This beat pattern is perceived as forward moving and is advancing in chronological time. It has fascinated a whole generation and spurred crazy movements to accompany the rhythm.
A simple tune might be played in reverse order as well. Just take a piano scale and play 1 2 3 1 fingers, and then 1 3 2 1 in a mirrored fashion (1231 1321). Even 1 2 3 1 as 3 2 1 3 gives an impression of inversion.  Through this composition technique you get a bit of a feeling for the potential of a reversal of time or what negative time might feel like.
The innovation through quantification challenges our concepts of time more and more. The direction of time is subject of a fundamental revision. Theoretical concepts have predicted this for a long time.

Quantification

The most obvious association with quantification is the attempt to quantify in the sense of measurement of situations, locations or social phenomena. This has taken considerable steps with the availability of smartphones that measure and thereby quantify all sorts of wanted and unwanted information about us. The distances walked are among the easiest to quantify. There have been many accounts and discussions about this kind of quantification. The results have been a further push towards self-optimization assisted by a quantification of almost all aspects of life. That is daily business of social sciences.
Quantification has another well-defined meaning to it, which is in physics. The revolution of the early 20th century has been to deviate from classical physics which assumed continuous processes in time and continuous measurements to the new world of quantum physics, another kind of quantification. This allusion is due to the Alain Aspect’s inspiring book “Si Einstein avait su” (2025) and his efforts to make quantum physics understood to a broader public. For me one of the merits of the book is the reminder that experimental physics can contribute and resolve many epistemological questions.

Time Concepts

Tell me about your concept of time. How do you define time? Answers to this question are likely to depend on your upbringing, affinity to a specific scientific discipline or epistemological belief(s). Aristotle defines time to be subordinate to the more basic principle of change. To understand change we need the concept of time. Two points in time define time, intermediate points are possible, which might be interpreted as a precursor of infinitesimally short spells of time. To explain change, Aristotle refers to his concept of time. Other concepts of time build on the notion of succession of events or sequences of events.
Clocks going round in circles have been used to show the progression of time independent of events. Beams of atoms later allowed for more precision of time keeping. The prevalent concept of time still is dominated by the idea of time as an arrow, usually depicted in some diagram resemblance based on the Cartesian coordinate system, but usually starting at 0 or a particular point in time as diagrams in economics.
Following on from the old concept of change and time, we still claim for causality in most day-to-day experiences or for social processes the link to a chronological progression of time. In statistical analyses building on time-stamped occurrences we may use event history analyses or stochastic differential equations to analyze (social) change depending on one or several (earlier) factors. Even the theory of deterministic chaos, which is applied in weather forecasts for example, arises from the sequence of point of measurements.
Mainly since Isaac Newton we cherish the notion of a universal time, which helps us to coordinate different locations on our planet with reference to the Greenwich mean time. Other concepts of time make use of infinity of time and how to deal with this. Life before, or life after death, are human constructs trying to make time understandable or at least manageable for us beyond our own living time. Depictions of time in the arts, paintings or music opens up yet another vast space of thinking about, as well as, experiencing time. We did have and still do have a great time thinking about time.

January Spring

The early signs of spring in Europe usually show up in March. The monthly data from the Copernicus Climate Change Service (C3S) show that „average temperature over European land for January 2025 was 1.80°C, 2.51°C above the 1991-2020 average for January,“ (Link). The warming throughout January has several consequences. Vegetation starts into spring earlier. This means that people with allergies of early flowering suffer earlier during a year. Winter rest in animal lives will be shorter. The risks of droughts in some regions combined with floods in other regions is increased as well. Rockslides in the Alps and flooding in Italy and the Baltic states add to the costs of climate change. 

Western Europe, witnessed a relatively „dry January“, even for those who kept drinking alcohol throughout the month. Heating and heating costs came down a bit and friends of gardening were surprised by some early showings of flowers of spring even in Paris neighborhoods (image below) as early as the first few days in February 2025! Strange new world. It all seems to happen a bit faster than most scientists expected. Time for adaptive behavior is shortened as well.

Review Year

It is a nice common practice to wish „A happy New Year“ to people at the beginning of another calendar year. It is also a good practice to review the last twelve months yourself or with friends. We spend,however, much less time to listen to friendly or enemy fire as a kind of evaluation of what were the successes and failures of last year. In monarchies in the middle ages a clown or a fool was allowed to present criticisms with funny packaging. Nowadays, comedians have taken over this important role to review experiences and policies that worked or went awfully wrong. All media join in in this tradition and summarize what happened before the next busy months take over. Yes, it is important to devote time to this procedure. There is a risk that it becomes „the same procedure as every year“, but it is never to late to learn from failures or simple mistakes. Failed last year, fail better next year.

Question Tomorrow

« Tomorrow is the question ». This is the imprint on the 8 table tennis tables in the Martin Gropius Bau 2024. As part of the Contemporary art exhibition by the artist Rirkrit Tiravanija, the tables are very busy throughout the day and invite people to meet, play and greet. If tomorrow is the question, today is the answer. Is it?  Maybe the answer is the day after tomorrow? Time appears to be the answer and the question. Such questions touch on basic philosophical questions about our relationship to and concept of time. Future orientation or even the belief in life after death touch upon basic religious beliefs. Intergenerational transmission is useless if there is no tomorrow or concept of tomorrow. Sustainability is most relevant if we are convinced there will be a tomorrow. Fatalists or warmongers rate today so much more than tomorrow that everything is subordinated to the urgency of now. Not easy to strike the right balance between „for now“ and „for tomorrow“. Simple financial discounting of benefits which accrue only tomorrow do not solve the urgency issue of behavioral concerns. My personal discounted value of ice cream tomorrow might be superior to ice cream now, but it is based on the tacit assumption that the shop still exists tomorrow or any other time in the future. The exhibition invites people not only to play table tennis but also to discuss the question of tomorrow across language barriers and across tables and cultures.

On Temporality

Time is passing, or is it? We tend to confound time, with passing of time or an occurrence at a specific point in time. Time has a static use, which refers to a date of birth or date of death. Time refers to durations like the lifetime or time in office of a person or a political leader. In most such cases time is considered as a continuous and linear process. The concept of temporality questions these common perspectives on time to allow additional time perspectives in the description and understanding of time.
Temporality is linked to a more flexible view on the periodization of history. The time before and after the 12 years of Nazi-terror will then be part of the extended periodization of the Nazi-Regime in Germany and Europe. Similarly, temporality widens the perspective on social phenomena by linking historical events to the time before and maybe even to what follows, seen as a consequence of the temporal and spacial co-evolution.
A deviation from the static view of time and a rigid periodization of fascism allows to study the Russian male dominated political authoritarianism as a new wave of fascism in Europe, which negates the right of existence of the state of Ukraine in its neighborhood.
Temporality expresses the need to go beyond a simplel periodization to include a spacial dimension  in the defintion of time, much like modern physics does in relativity theory. Temporality, therefore, opens up a “thought space” beyond just the timing of events, which may challenge many of our day-to-day experiences. Cultures with a different understanding of time or the pace of time become a “sound board” for our way of considering and being captured in a time space. Probably many artists are forerunners in playing with time and the way time is “treating” them. Most of them face(d) hardship during their lifetime, but have an extended “after life” in terms of reputation. Some contribute to the perodization in the arts and of their time. They all shape(d) temporality.

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.

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).

Commemoration Paris

The cemetery “Père Lachaise” is a spacious area of commemoration in the 20th arrondissement in Paris. Many famous people have been buried there or moved to this cemetery eventually. Edith Piaf, Gustave Caillebotte or Frédéric Chopin are known across borders. You find also a small monument for the controversial founder of homeopathy 200 years ago “Hahnemann” there. He spent his last 8 years in Paris before he died at the age of 88 in 1843. From a social science perspective it is interesting to note that commemoration is much more decided by the descendants like in the case of Hahnemann or the popularity of the person, like for Piaf, than the person her/himself. The tradition of joint graves for families holds for the Paris born painter and collector Gustave Caillebotte despite his movements to other places. The freshly cut flowers on the grave of Piaf show that the performances of the artist have made deep and lasting impressions.
