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.

Corruption Caught
In fraud or corruption it is primordial that the probability to be caught is very high to deter potential fraudulent activity. The new Trump administration has enacted as one of the first executive orders that the FCPA stops to take on new cases of suspected corruption as well as reconsider some of the running procedures. In the same vein, the Corporate Transparency Act (CTA) has been silenced so that American companies to not have to disclose ownership information that fall under the CTA until 2025-3-21 until a major reform will be published.
These policy shifts concern more than just US citizens. The competition between countries will be effected because as companies trading with the US which used US bank accounts were also liable under this legislation and subject to prosecution. The FCPA has been an important example for other countries to follow at least within the Member countries of the OECD. The shift in priorities of the Trump administration might open doors again to corruption which we believed were shut with lasting effect.
In conjunction with the rapid increase in military spending when the capacity for the production of military equipment is slow to increase might increase the risks of corruption talking hold again. Market economies build on fair competition, but less prosecution of corruption introduces a bias into negotiations which works against innovation and competitiveness. We have a hard time to understand any kind of logic in such economic and legal strategies.

Berlin Mind
For a long time now, I have been asking myself the question: What is like to be in a „Berlin state of mind“. The exhibition of the 2 photographers of the Berlin Landesarchiv as part of the Berlin activities of the EMOP contributed to understanding and more precise description of the „Berlin state of mind“. As we shall celebrate in 2025 the 80th anniversary of the liberation of Europe, Germany and Berlin from Nazi rule and terror, we have seen endless reconstruction and reshaping of the city. The ever growing need for housing and space-grabbing office buildings bring about a permanent feeling of change, of becoming, of under construction. The years of the separated city as well as the building and taking down of the Berlin wall created many new opportunities for developers of the city and its structure of quarters, arrondisements or „Bezirke“ and „Kieze“ within the districts.
Due to the continuous urban renewal also of basic infrastructure Berliners have the impression that there is construction work all around us all the time. With the abundant construction works come the construction fences. They too have changed. Some fences show digital prints of virtual worlds of the Berlin living in some future time. However, the promises often mask the reality that fences will be replaced by concrete walls and inaccessible buildings for most people of the neighborhood as gated business space or city blocks grab the space to form and reform the metropolitan landscape. The construction fences themselves become the contested areas where different strata of society interact or intersect. The „Berlin state of mind“ is one of becoming. Longing to become something else, something aware of the overwhelming historical duties, but still rising from the ashes. The experience to see a wall come down between cold war enemies liberates a belief that we can overcome frontiers. However, this in-between state of mind has brought us multiple fences of all sorts. Construction fences are only the most visible ones that surround the many spaces under construction. In the imagery of Berliners and visitors beyond the wall, fences are continuously on our minds in the „Berlin state of mind“. 
Top 5 Things T5T
Dealing with Elon Musk is a must these days (WSJ 2025-2-26 A4).
So it happened that on his way to Mars, Musk met God the almighty on his way back to heaven. Musk asked, whether he could join the ride.
God, not amused, asked Musk about his T5T (top 5 things) he accomplished in his life. Musk questioned God‘s right to ask this question and said he would tell the other T about this. God gave him just another day to come up with a response.
So here we are: the T5T Elon Musk might put forward:
(1) I created a million fancy electric cars.
God: Well, but there were already too many tin boxes on 4 wheels on earth.
(2) I created rockets that propelled billionaires into space and back again.
God: Your carbon footprint has exceeded a million people of the poorest countries on earth.
(3) I created a network of satellites that facilitated communication.
God: Nobody spoke to me yet using it.
(4) I bought Twitter and transformed the platform to spread evangelism of various sorts.
God: This has become a hoax spreading more lies than truth.
(5) I reformed the public sector employees to share my beliefs or leave.
God: This will ruin a lot of services like USAID, which have assisted me for many years in my caring and charitable service.
With all these T5T of yours in mind I am not sure I should let you return to that planet earth. Maybe I‘ll find another assignment for you where you can cause less harm Elon. Maybe, try “Waiting for Godot“.

More BRICS
The move towards a multipolar world order is in full swing. With the USA retreating from a primordial international role discarding UN institutions and the defense of major elements in the fight for individual freedom, the diplomatic order of the last 80 years has changed. The liberation of the concentration camps in Germany and the 80 years of the end of the 2nd World War on 1945-5-9 had forged an alliance in which the common enemy was defeated and the the next major confrontation in Europe or on the globe had to be warded against.
The evolution of peace in Europe has been marked by the Cold War and a bipolar world order which confronted the USA and Russia at various places. The rollback of Russia has seen its high time with the Northern and Eastern extension of the EU and NATO. This goal of US strategic interests has been largely accomplished.
In the shadow of this bipolar relationship the BRICS have moved towards greater economic power and therefore influence in the international arena. Economic data on the biggest economies in the world over the last years show the rise of the BRICS, bit mainly China and India. Their population sizes create enormous and largely shut off internal markets. All these developments create new challenges to the previously relatively stable world order. Technological advances have been narrowing more rapidly than before since the access to the best available knowledge spreads fast and more equally across the globe through the internet.
The ugly face pf imperialism is returning front stage and attempts to change the previous versions of imperialism into a new hegemonic world oder. Updated views of economic power and influence zones let us look with a rational perspective on the new power play. Due to the containment of Russian influence, the USA has China as the major power to confront, a major shift as of the 2020s. The China-driven Silk road project with strategic landing points across the globe has „trumped“ American efforts to align BRICS to human rights values over the last decades. European diplomacy will have to recognize that we entered another phase of „Realpolitik“ due to major economic shifts over several decades.

Revealing masks
Masks can have multiple functions. During the Covid-19 pandemic from 2020 onwards we developed a hate-love relationship to wearing masks. Carnival traditions give wearing masks yet another touch. The painter James Ensor added other meanings to a mask. They do not disguise the person wearing them, but might make otherwise difficult to see features of a personality more visible. In a donation initiative and auction to raise funds to fight cancer Yves Delplace made the biggest contribution through his donation of the painting „Intrigue année 2024. Le preneur de selfie” of which we represent only a partial extract below. In 2025 this depiction of 3 leaders of big countries has gained unexpected relevance. The US and Russia partying jointly while people still die on the battlefield die to Russia‘s invasion of Ukraine has been turned into a cynic depiction. James Ensor and the surrealists in general would have appreciated this application of their way to deal with or foreshadow coming events. For some people you think it is about time to take off their masks or somebody to take it off. For others like Putin, the friendly looking mask has become apparently a frozen expression despite of the underlying ruthlessness.

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.

Blue Sky
In the period of romanticism the associations with a blue sky were very different from today. Getting out into the sun was a kind of privilege for the “leisure class”, of people who could afford to enjoy time outside for boating, walking or other pleasures. In our technology-driven 21st century the associations with Blue Sky are more like a technically enhanced view through for example “Windows” at the news and opinion platform or “Bluesky”.
Several scientific websites that report data on blue skies and air quality more generally across the world report indicators like ozone values O3, sun intensity, micro particles 2.5µm and 10µm, Nitrogen Dioxid NO2 to name the mostly quoted indicators. Hence, just enjoying the blue sky outside isn’t the same as it was before. People working outside in the sun or at times of a blue sky but with high air pollution levels are incurring severe medium-term health risks. The Ozon layers at very high altitudes protect our skin and eyes against high UV-radiation, but O3 on the ground is tough for eyes and lungs.
Technology has come with many blessings, but the negative effects on a global scale become also more evident. Getting used to a particular lifestyle, which produces lots of emissions of aggressive fine particles will make it more difficult to just simply enjoy a blue sky.
In consideration of all these background data with regional variations, we surely need an AI-system which we can ask for advice, whether we should go outside and enjoy the blue sky with or without respiratory mask.
Romanticism has led us all the way to Californication and dangerous enshittification of the air that surrounds us. Youth and the next generations will have very different associations with Blue Sky than we have the chance to, at least, have had. 
Mindmap Me
Tools like artificial intelligence allow all sorts of transformations and depictions. The photo editing tools are widespread and particularly popular among the young users. My own transformative exercises, latest with www.bairbe.me, have yielded interesting insights, well worth an intergenerational playmate. For the guys there is the www.yobrick.com version for brick gamers. 
The App “Canvas” allowed me to delve deeper into my own mind by giving instructions of how to create an image of the structure of the blog entries on this webpage. Of course, it is not (yet) a real AI-generated content map, but it is only a matter of time until such tools will exist. After all, this would be just an arranged and rearranged list of contents using the hyperlink structure of the texts as well.
For the time being, I derive my own structure of the blog entries by topics, categories and tags including the hyperlinks or internal referrals. Interlinkages are mostly stated explicitly. However, there are many implicit links, which are obvious to some, but not others. AI-systems could use occurrences of words, synonyms and antonyms . Colors in addition to bubble sizes and (in)direct lines may complement such mindmaps. This can help to reveal another, additional layer to connections between categories or tags. The Ai-generated image shown below was created with the APP Canvas as a first approximation and AI-augmented test version in form of abstract images).
Next steps on the way to understand human intelligence and, maybe, augment it with a next generation AI-system would use a colored-3D version of such a mindmap and use the chronological evolution of the blog posts in a kind of evolutionary animation. This should allow us to go beyond the usual psychological classification of fluid and crystallized intelligence. We might come to grips what it means to be “in a Paris state of mind” or when hallucinations become overwhelming.
Endless Questions
The winner of the Niépce prize 2024 has been awarded to Anne-Lise Broyer and features prominently at the BNF in Paris. The exhibition of the professional photographer reflects by way of photographic “still images” on the historic fate of the mediterranean basin. Each and every image has no answers, but keeps posing questions. In the long alley of the BNF in honor of Julien Cain, we walk through history of more than 2 thousand years in photographs up until today and even beyond. Let’s keep asking the most fundamental questions again and again. The exhibition entitled “Est-ce-là que l’on habitait ?” invites us to ask ourselves about the historic origins of so-called Western culture in the mediterranean basin. Ancient philosophy and arts are the foundations even of our current ideas of democracy and freedom.
However, what has become of this in the 21st century? The original statue of freedom has suffered badly. What has become of the freedom of mobility at a time of barbed wire fences rising between countries that influences each other over thousands of years? How about nature? How about religion and freedom of expression? Where is progress? Where is regression?
For centuries we have sought answers in libraries starting from the Library of Alexandria to the treasures of art and knowledge of today across the world. Let’s make more intensive use of these treasures where we shall find answers to most of our questions of the past, to the past and of future interest.
