AI Racing

AI has entered the racing of cars after we have been racing horses, dogs and camels for many decades. The fact behind all these races is the huge market for gambling. Anything you can bet on will do for juicy profits in that industry. The recent “Abu Dhabi Autonomous Racing League” is the latest addition to the racing craze. Moving online with 600000 spectators at its peak on video and gaming platforms the investment seems promising. The only problem, AI is not yet ready to really compete with the world of real drivers. The progress, however, is astonishing. Just one lap of 2 minutes on the circuit yields 15 Terrabyte of data from 50 sensors. These are closed circuits so no person can enter or animal can get in their way. The challenge to integrate more data and faster processing as well as algorithms for fast decision making is steep. Great learning opportunities for advances in robotics. The hype has not been able to live up to the expectations as no real racing took place yet. We have replaced the gladiators of the Roman empire with Formula 1 drivers. It is only fair to retire those drivers soon and let AI race cars against each other. It feels like a computer game on screen and it is as we shall most likely watch these races on a screen as well. Hence, what is the point. Watching youth on TWITCH play racing games will probably not change the viewing behavior of the masses. The programmers have nevertheless great learning opportunities and will find their way rapidly into the job market. The other challenges of ASPIRE seem more important for humanity like human rescue and food for the growing world population. In the meantime let the boys play around with cars and learn about potentials as well as failures of AI-programmers and dealing with both.

Barbie Chemical

Chemistry is sometimes perceived to be uninteresting, but only until you realize it might be beneficial to know more about some underlying chemical processes. The Royal Society of Chemistry has finally found a topic in chemistry to give chemistry a popular push. The Barbie hype is far from over as we all learned in the recent past. Now conservationists have found a topic with chemical processes involved to demonstrate the usefulness of chemistry knowledge for the conservation of your treasures or collections of plastic dolls or puppets in general. Most plastics PVC was not intended to last, but the deteriorated forms have a long lasting effect in form of PVAS or microplastics. So aging research has reached popular concerns like the aging of Barbie, who is believed to be “forever young”.

Science Politics

We tend to believe that science is independent of politics. Even if the individual scientist does research and studies free of immediate political influences, there are many ways in which politics has an impact on science. Sociologists refer to Max Weber as a prominent figure in the “Werturteilsstreit” that claimed the need for science to be conducted beyond political interference. Karl Popper is another reference in this respect who proposed the positive science approach which starts from theory, hypotheses and testing in the sense of identifying false statements, hypotheses and underlying theories. Modern science is also linked to publications of results. This has become an industry of its own and it is sometimes quite surprising to see the lengthy delays that scientific results get published. One example, Jackie G. Schneider and Julia Macdonald (2024) had to wait 3 years until their paper finally appeared in print in a scientific journal. This paper was received by the Journal in February 2021 and published only in 2024 in the 2nd issue of the journal but online in January 2023! Reports in Nature on difficulties of Indian, African and Chinese scientists to get their work done and published are alarming as well. Further regionalization and departmentalization work against the fundamental principles of independent science and scientists. It is a big issue of international cooperation as well.

Time Perception

There are many different angles from which to look at time. Of course, we all do it several times a day or during boring meetings. The study by Ma, Cameron and Wiener (2024) highlights the bi-directional link of perceived time and memorability. Visual stimuli alter our perception of time. Watching a video we all make the experience that the perceived length of the time spent watching varies according to content and maybe only the cutting technique applied to shorten the perceived length. Similarly it has been demonstrated that looking for longer at an image and grasp the meaning or implicit story we tend to remember the image for longer. In courts it is a usual procedure to question the memory capacity of persons and the sources of bias. The study by Ma et al. demonstrates the impact of the size of the scene, how cluttered it is and aspects of memorability in visual perception. Our memories are co-determined by these factors. The other direction of causality i.e. that memorability determines the time perception seems equally at work. This apparent undetermined element, so far, calls for additional care when analyzing recall from memory. Memory is not only selective in terms of content, it also is subject to the impact of all sorts of visual stimuli.
Time can be many things. For humans it is everything but exact. In science we measure time with ever more exactitude and try to standardize time on the moon now. In addition to exact time, humans have perceived time and subjective versions and even concepts of time. About time to take time more seriously.

Hospital Bias

Asking people about differences between private and public hospitals, you are most likely getting answers that the private hospitals deliver superior patient outcomes. Whereas private hospitals seem to have a positive stigma attached to them, public hospitals commonly have a negative stigma. Scientific evaluations are helpful to set the record straight again. The study published in “The Lancet Regional Health” in 2024 shows that in the simple descriptive statistics on several patient outcome indicators, this is what the data showed between 2026 and 2019. However, a more precise statistical analysis reveals that there is also a selective admission to the private and public hospitals in England. Using so-called instrumental variables approaches that account for the selection process between admission to the 2 types of hospitals (private versus public) most of the differences between the hospital types disappear. The underlying mechanism is a sorting of different patients into the private or public hospitals. Put in easy words, for a routine intervention people tend to chose the private hospital, but the more rare and difficult operations were more likely admitted to public hospitals. The number of co-morbidities (heart disease) is also of importance as they might negatively affect patient outcomes. Jumping to conclusions and reinforcing stigma about public or private provision of services hinders progress and an equitable provision of services.
The analysis of a potential selection bias can reveal the “creaming” effect of private provision of (health) services. Just caring for the “easy” or routine cases and avoiding the more difficult and costly cases has economic advantages, but for society as a whole the costs overall remain the same. A good public service in health is a definite asset.

Digital Estonia

The progress of Estonia in going digital is quite advanced. The electronic identity card which allows data to be linked to health data and accounts or banking gives an impression of how far-reaching digitalization may go. Great steps have been taken to guide the population on the way to move towards the digital (only) world. Learning and coaching of a huge amount need to take place so that people do not abandon or get lost on the path towards “everything digital”. For the so-called digital natives, who have grown up with the sound of their smartphone at the bedside all the time, this move feels “natural”. Some experienced or silver workers got on track, if they were accompanied in suitable forms. The 65+ population might find it harder to adapt to the permanent use of digital devices for not only getting around in your city, but also to do your tax declaration, pay your dues and vote in elections.
Digitalization is not a goal in itself. It has advantages to reach communities in remote places or islands, but it might alienate older persons that have no other person around to assist them in the digital only world. An easy way to get some social science data to inform the debate is to refer to Eurostat and the surveys with information about the “overall life satisfaction” of people (EU-SILC). Checking for some major countries of the EU and neighbours of Estonia with less digitalization the differences are rather small. In terms of overall life satisfaction (16+ years old) Estonia has been catching up to the EU-average mainly between 2013 and 2021. Since then, stagnation at the EU-average is what the data tell. A quick testing of the hypothesis that the older persons (65+) might not see the past evolution as rosy is reflected in the EU-data as well. Good pensions seem to drive the “happiness” of older persons in the EU more than good digitalization. Eventually the two features of a society will have to go hand in hand to improve life satisfaction to higher levels.

Electricity

We all use electricity, not only daily but continuously. But do we really know or remember how it works? Surprisingly, we care very little about the energy provision or the physics behind it. Therefore, from time to time it is useful to dive into the details of generating electricity and thereby energy and how it arrives at our doorsteps or desks. In science museums you can literally walk through the history of power generation. A fine example is the Energy Discovery Centre in Tallinn, Estonia. Even for those you did all at school turning the handles of generators is a playful reminder of the basic principles of electric power generation. The efficient use of it, is a topic that needs to be covered as well. Searching the web for demonstration videos is fine as well, but the physical activity of moving induction coils and releasing sparks is difficult to rival. Opening up your mind for the physics of our lives yields a better grip on the challenges of electricity grids and local production of electricity. Are you already a prosumer? Combining electricity production and consumption in one household is surely a forward-looking strategy. Raising awareness for these topics concerns all generations. Take time for a power play, it is truly enlightening. For teaching professionals or want to be there are exciting programs out there, too. Just one suggestion for 2024 in Colorado, US.

Theory Literature

There still is a lively debate at the margins of literature and the commerce around it about theories of literature. Even if the best of years of theories about literature have passed, in 2024 we see several revivals of theoretical perspectives on literature. Travelling in Europe we celebrate, for example, the 100 years of Belgian and international surrealism in Brussels. The French artist and theorist André Breton was preparing in his thoughts the art and literature of surrealist inspiration. Of course, we think of Magritte as one of the eminent figures of the painted surrealism. Franz Kafka, who died relatively young in 1924, was the author in the spirit of the surrealist movement. The powerful impact of literary theory and theory of art to form communities of practice have had lasting effects, which fascinates large audiences in 2024. Exhibitions across Europe reflect the importance of these art movements to understand European culture, inspirations and aspirations.
Not least through this revival of the surrealist artists in the broadest sense we are returning to a more theory-driven view of literature a bit like 100 years ago. I find it remarkable to read in “Le Monde Livre” of 2024-4-12 the article on “Défense de la théorie” by Tiphaine Smoyault (p.8 see quote below) with a comment on the book by Florent Coste on the usefulness of a theory of literature to understand the world around us. Reworking of language is the contemporary concern of literature: pluri-linguistic experiences, re-discovering oral performances, irony in language and digging into archives are the major strands of contemporary literature. Theory of literature reflects on the past and allows to synthesize the present. For some it also enables to project into the near future of what is going to be published. In any case the theory of literature provides orientation in a huge ocean of published oeuvres. Writing or painting with ideas ahead of your time has been a painful experience for most of these artists. Some artists or authors are lucky to become famous during their lifetime, but lots have struggled for years or never learned that their contributions advanced humanity for more than a hundred years.

Causal Benefit Model

In the field of medicine we move more and more towards precision medicine. Previously, the term of personalized medicine was used which suggested to a certain degree that a personalization might be feasible. The budget constraints have forced us to change the term to avoid unrealistic, untenable promises. In the field of cardiology scientific advances advocate to shift from a risk-based model of treatment to a causal benefit model. (Kohli-Lynch et al. 2024 Link). Long-term benefits of a treatment are more promising, if the treatment addresses the causal mechanisms at work. It is wide spread practice to deal with general risk profiles as guidelines as the precision medicine based on a causal benefit model is far more laborious since to search the causal mechanism at work requires additional testing of hypotheses. This becomes immediately clear if genetic causes enter into consideration. Nevertheless, medical research advances more and more in this direction. Genetic testing has been shown to be useful in analyzing and treating issues like sudden cardiac arrest (in survivors). We are somehow aware that genetics may play a role here, but we shall need a lot of additional studies to make the causal benefit model a feasible option for widespread applications. Targeting research in this field will offer new avenues for precision medicine in the 2020s.

Series Evaluation

The monitoring of TV series is a serious science. The evaluation of so-called binch viewing has redrawn attention to the field of media studies again. We observe a bit across Europe, following the US experience, the change of TV productions into series that may run over several years. The successful format of a TV series draws advertising to the relatively constant audience. Most series have a particular age group as their target group. Viewing behavior determines time slots allocated. Each group has its own prime time. The publisher of books had their successes with similar series of for example children’s picture books or cartoons. Asterix, Martine and similar book series have basically applied the same “serial” mechanism before. Popular success creates its own dynamics. Therefore the evaluation of such serial productions should stay on our research agenda of the social sciences as well.

In a radio discussion “France Culture” has juxtaposed the 2 currents of series evaluation in a concise way. One current of assessment holds the view that rather than high versus low culture, the debate should take popular culture seriously. It augments the set of experiences as the characters in a TV series live through a kind of “experimental setting” each time anew. The variety of experiences is catching popular attention as they are beyond the scope of the spectator’s usual life settings and thereby a learning opportunity. This highlights the value of the content in the evaluation. This requires a thorough scrutiny of that content to evaluate an emancipatory value of viewing it (Sandra Lauglier, 2023).

An opposing view is defended by Bertrand Cochard (2024) with reference to the conflict about one’ use of free time available to us and how we spend it. His criticism takes issue with the amount of time “lost” by viewers of series. Time is not spent twice. The loss of time alone or side by side rather than spending it with other persons or physically active constitutes a major risk to the social fabric of society.The jury is still out on the issue. We likely see the start of a series of entries on this topic as well.
