- The whole new business area „La Défense“ was a huge investment project with international speculators highly motivated to reap the benefits of a business location just next to Paris, which at best would even feel a little bit like being „intra muros“. However, being at La Défense you see „L’Arc de triomphe“ only quite far away and you don’t really get the impression that you are in Paris. The high rising buildings around there originally gave god reasons for expensive office space. Few residents spaces made the area uncomfortable in the evenings after office hours. After 2025 most office spaces no longer are attractive for businesses and lack behind environmental standards of the 2020s. Many projects attempt to renovate the former office space into residential buildings with a considerable loss in the value of previous office space. For people working in the multiple shopping centers there this might be a feasible option if the rent is not excessively high. Students in transit through Paris might find this attractive as well. Families, however lack an adequate infrastructure as this area was built for an outdated business center and business model where families were believed to obstruct business efficiency. As the project developers have written off their investments over 25 years society can clean up the remaining space and repair. It will be another medium term project to re-create a convivial environment and community there as before the overriding device was make money there and run to a more human and diverse space.
Expo Disco
The combination of music and dance is a powerful, captivating experience. From folk dance traditions across the globe to ceremonial performances. In the past this combination has often related ro religious practices. Later manifestations include classical ballet, modern dance and disco music and dancing. History is full of examples that have been turned into mass culture.
Rock on festivals and rap in clubs or hip hop outside have complemented this experience over the last few years. Each time the combination made the popular difference. Therefore the Disco exhibition in Paris just next to the Conservatoire de musique et de dance de Paris and in the building of the Paris Philharmonic is an appreciation and respect to the disco culture, popular mostly during the 70s and 80s. From a sociological perspective the throve by minorities for recognition of their cultural practices and diversity has been a driving force. Andrew Diamond has coined the expression of „disco at the intersection of minorities struggles“ (p.70 exhibition catalog). At the origin of the disco movement, there was the aftermath of the 60s power struggles. Black, women, gay and student protests asked for „all power to the people“. Music and dance were forming identities. Posing and showing off became part of disco. People created and lived their own utopia in glamorous lighting.

Präludium Prélude
Learners of how to play the piano are likely to pass the composition of J. S. Bach entitled Präludium in German and Prélude in French. Maybe that influences the approach to the piece of music. The title sounds different in each language. It is interesting to follow the Präludium Prélude throughout the history of composition. The pianist Jan Lisiecki has just recorded and released a disc with Deutsche Grammophon following the historic evolution of this genre. The rather easy-going beginnings by Bach (see below for extract of first motive) have turned out to become rather complex preludes with subsequent composers. We may ask ourselves at this occasion: a prelude to what? Your own associations are welcome. In international politics we can observe strategic movements of countries and their military equipment as a prelude of war, but also of peace. Small aggressions may turn into wars. In philosophy Nietzsche praised the dawn (Morgenröte) and focused a lot on new beginnings. Composers might be the best forecasters of what is to come in the following years. Certainly the preludes have foreshadowed some of their later work. Nowadays, many LLMS in AI build on algorithms that predict what is the next word to write or task to do. Even in composition AI is moving ahead fast. Hence, we e are likely to study preludes much more for several reasons now.

Hands-on AI
The use of AI in translation and to streamline texts and preparation of communication has become a common experience. The applications in medical fields are less well known. Scans and checking of skin cancer could be a game changer for many who live far away from the next medical doctor. AI assisted brain surgery is another issue, but a very specialized application. The interface of AI and robotics might be another game changer as such applications where you train the robot with for example weight lifting and transportation charges can contribute to alleviate human skeletons. Handheld devices can guide the robot and data from sensors will complement the learning of the tasks through assistance from AI. Applications are manifold and we have not even seen the most promising ones. The application potential in warfare are particularly troublesome as humans do not necessarily enter into the concern of AI-assisted weaponry. In the social sphere trust is a crucial behavioral and ethical concern. These issues AI can only learn from us. Any attempts to do without human input and control is doomed to fail. We are not indispensable yet, we are simply turning more and more into responsible, supervisory roles.

ravel up Ravel
To ravel up is a contranym. It can take a specific meaning and the opposite at the same time. Therefore, it is a perfect term to describe the composer, pianist and conductor Maurice Ravel. Born in 1875, he lived through great deceptions as aspiring pianist at the Conservatoire de Paris, but achieved glory through his famous compositions like the “Boléro” created for a ballet performance at the Paris Opera.
Previously, he had written several remarkable piano pieces, which were recently honored by the piano music magazine “Pianostreet”. In an article with links to 5 performances of Ravel’s piano compositions you can ravel up in the emotional world or cosmos of Ravel. You may also unravel his compositional style marked in some of his most famous pieces with the variations of a single theme or motive. The “Sonatine” completed in 1907 might be considered as a precursor of later work (Boléro) as he refined his composition techniques to build, for example, on a single motive and develop a whole piece reworking and with reappearing incidences of the same motive.
Ravel himself appears as contranym, as he combined modern musical influences, like from jazz or innovative structures of musical compositions with the classical forms of composition. Listening to Maurice Ravel allows to better understand the transition from classical music to modern worlds of music. Thanks to “Pianostreet” we can follow these paths. For a biographical account the splendid movie “Boléro” takes you on an unraveling musical journey of Ravel.

More eCooking
Cooking powered by electricity rather than fossil fuels like gas is an efficient and smart solution. Through the daily cooking activities over the course of a year the savings due to eCooking add up quite a bit. Even compared to an ordinary electric stove the eCooking by induction technology saves almost an additional 10+ percentage of energy as you heat the pot or pan directly rather than an in-between metallic element, which stores heat even after you have switched it off already for a while. In private kitchens the induction option is straightforward. In professional settings the change to induction eCooking needs careful planning. The health aspect of no burnt gas emissions in the kitchen is, however, a strong argument in favor of eCooking as well.
If we apply this logic to low-income countries and cooking in schools or other institutions as well as companies, the environmental and economic benefits add up quickly. In rural areas where no electricity grid is available or stable enough, the decentralized provision of electricity through for example solar energy creates a cost-effective alternative. In urban areas with high levels of various kinds of pollution the “clean” alternative could make a considerable difference as well.
The eCooking evidence is another pillar of the “all electric society” of the 21st century.

Known Unknown
Many musicians and poets remain unknown to larger audiences. “A complete unknown“, young singer, musician and songwriter Bob Dylan has reached fame and fortune with his poetry and popular songs that marked a whole generation. He became the best known unknown of country music in the USA who found sympathy for his expression of protest across the world. „How many times must the canonballs fly, before …“. At the time of renewed militarization of the Western states to defend our way of life, the protest song is oriented towards Russia to stop its war in Ukraine.
The poster in Berlin to advertise the biographical movie on a „Litfaßsäule“ (round sign posting column) dating back to the 1920s in Berlin brings us back into the historical state of mind of crucial crossroads in history. Retreat from war, preventing war and aggression remain topics for us today as well. Peace might be the happy time in between wars marking history.
Berlin is a great place to walk through more than a century of war and aftermath. Rebuilding takes decades and is part of the Berlin state of mind. as well as a sign „to overcome“ conflicts.
Democracy ART
The European Parliament co-sponsored a remarkable art exhibition in 2023 entitled „Art in Democracy“ The catalogue of the exhibition offers insights into the many preconditions of art. A democratic environment constitutes a non-negligible precondition for most of the works of art. Artists thrive within democracies. Many artists flee authoritarian regimes as their work environments rely on a real freedom of expression irrespective of the will and belief of ruling politicians.
Artists who do not flee in time for whatever reasons have suffered tremendously under Nazi terror in Germany. Authoritarian leaders don’t respect the various forms of expression by artists. Europe and the European Union provide safe havens for many artists to continue their careers in art. This has become a real value of our way of life. Many countries envy us in this respect. We take this for granted in the EU, but 70% of the world population endures authoritarian control. A reminder of this, from time to time, justifies a lot of expenses to support art and artists even beyond our borders.

Minority Politicians
We have regulations in favor of minorities in many countries. Most people immediately jump to their opinions about specific minorities they most strongly feel about. Favoritism through targeted policies versus discrimination are key issues here. Evaluation of effective policies to support minorities needs solid science before jumping to premature conclusions.
A recent study on the largest minority group of extraordinary people, often denoted as persons with disabilities, has focused on political representation. The results confirmed the hypothesis of an under-represention of the group in parliaments. Reher & Evans (2024) show ample evidence that despite the large and increasing shares of persons with disabilities (about 20-25% across Europe) under-represention is likely to lead to lack of concern of society as whole to topics of relevance to them. By-the-way, most of such policies would equally benefit an aging society and young families for example with regard to mobility. Perhaps another striking example is the tendency of extraordinary persons to not report their kind of disability out of fear of stigmatization and potential discrimination.
Policy makers need to take a long-term perspective to reorient public spending in favor of extraordinary persons. Infrastructure investments are needed here as well. More persons with disabilities across all political parties can bring about such changes. Extraordinary persons deserve equal representation. It is up to us to make it happen.

Bilingual Plus not WEIRD
The scientific literature on bilingual learning and living experience is abundant. Positive cognitive and social inclusion effects dominate the results. The scientific research has moved on to more tricky questions of bilingualism which shifts gear to multilingual learning. Many people and children are bilingual plus additional contacts to another or several other languages. Multilinguism has been of interest for several scientific disciplines. The effects on cognitive development have received a lot of attention. In order to achieve further progress in the study of multilingual development, it is instructive to move beyond bilingualism and the WEIRD particiants in most psychological studies (WEIRD = Western, Educated, Industrialized, Rich and Democratic). The paper by Omane, Benders & Boll-Avetisyan (DOI) takes this as a starting point and investigates the experience of infants with 2-6 languages.
They establish a protocol how to record the surrounding languages in a structured way. A major distinction into direct and indirect exposure to languages is a major finding. The example from Ghana provides a useful basis for other studies of multilingual experiences. A correct recording of different language inputs in time and of the sources is at the basis for later measurements of effects of different kinds of exposure and intensity of exposure.
