Dream together

„Dream together“ is the title of the exhibition of Yoko Ono at the „Neue Nationalgalerie“ in Berlin 2025. The title is an invitation or even an incitement to dream jointly with others. We need to dream of peace on all sides or parties in a war. Start with the dream and then move on to working together on it. The participatory art projects of Yoko Ono are a recurring event in Berlin and at the Neue Nationalgalerie (Cut piece). The installation „Wish Tree for Berlin“ in front of the gallery is popular with visitors who leave hundreds of written wishes to the windy spring days. Origami folding, stone assembling or a simultaneous chessboard playing with all white pieces and fields encourage to imagine a world differently, beyond the treaded belligerent paths. For more inspiration and imagination just continue to the Martin Gropiusbau for more artworks from Ono or just watch the clouds pass by changing the lighting of the olive tree carrying lots of wishes.

Permanently anxious

„There’s a set of forces that want us to be permanently anxious“, is the phrase chosen by Tony Cokes in the exhibit just outside the „Palais Populaire“ in Berlin in 2025-5. International politics and the economic upheaval caused by Trump’s tariffs contribute to the already existing other sources of anxiety like nuclear energy and warfare. Global warming causing more extreme weather events add more man-made reasons for anxiety. The next generations will have to foot the bills we have left to them unpaid. Our current shortsightedness increases anxieties which previous generations have not known of a similar kind or in that combination. 

Community building and solidarity are ways to overcome such overwhelming anxieties. Supranational organizations like the European Union have an even stronger role to play to reassure its people with credible signs of solidarity. We are not alone in the struggle to overcome the anxiety that is creeping up around us. We are certainly stronger together than individually dealing with unspecified fears. „We shall overcome …“

Margot Friedländer memorial

Berlin has been honored by the return of Margot Friedländer who had survived the Shoa in 2010 at the age of 88. Her whole family was murdered in concentration camps by the Nazis. Ever since her return and especially after her biography had been published she was a restless ambassador in the fight against hate, exclusion and the neo-fascist movements. She has been engaged in interreligious dialogue and even through the ceremony after her death, she tried to bring together different Jewish communities in Berlin.
Irrespective of a person’s background she met everybody on an equal level.
A great example to thousands of people, she managed to meet in her life. Each time she met with pupils or students to speak about her horrific experiences she lived through the same traumatic experiences again and again, but turning this into the strength to “vaccinate” people against the deadly virus of fascism.
The day after she had been buried in her family’s grave in Berlin Weißensee people still had to queue to sign the book in her memory in the Berlin town hall. She will be remembered and missed for her unrivalled humanity and generosity. She became engaged to fight for humanity and remained an activist until her very last day at 103 years of age.

Non-autonomous driving

The more engineers will invest in developing autonomous driving vehicles, the more the value of the few completely non-autonomous cars will rise. A 60 years old car with manual gear changing on the steering wheel like the Peugeot 404 from 1965 (image below) demands a strong effort to steer the car around a city. Apparently, some car producers reintroduce buttons to press or switch on devices since customers seem to prefer some manual activity in addition to the touchscreen technology. Voice guidance and gestures can be helpful for some, but there are also the advantages of manual activities that keep you awake and maybe with better focus. Choice is key to suit diverse user and customer preferences.

Leber JA

In Berlin Schoeneberg there is a memorial in preparation for the courageous couple of Julius and Annedore Leber. Julius Leber has been incarcerated several times by the Nazi officials, tortured and finally executed in Berlin. A link to the group of people trying to overthrow the NS regime (1944-7-20) caused his arrest and execution in January 1945. His wife Annedore published several accounts of the resistance movements, which existed during the NS regime. These people were aware of the fact that they were risking their life with such activities, but persisted nevertheless. We owe Julius and Annedore Leber a decent commemoration as we need to remember that such courageous examples existed even until the last few months of the NS dictatorship. The site allows for a building and learning center which could serve as an archive and encouragement to fight for democracy. It is less obvious than we thought it would be.

Constitutional Responsibility

The memory of horrors caused by Nazi-led Germany before and during the 2nd World War is our constitutional obligation in the Federal Republic of Germany since its beginnings in 1948. 80 years after the unconditional surrender this has become a state responsibility. Since the shift of tone introduced by Richard von Weizäcker on 8th of May 1985 framing the end of the 2nd WW as liberation day in Europe and Germany. On the same day, 40 years later, the top 5 political instances of democracy in Germany, president, chancellor, presidents of the parliament (1st chanber), the council of the regions (2nd chamber) as well as the constitutional court. The constitutional and moral responsibility of the crimes is not reserved to a presidential address, but all pilars of democracy in Germany committed to the narrative of a liberation of Germans and Europeans at the end of the 2WW. It is a truly European topic to celebrate the end of war jointly in all countries. This is even more the case as the memories of the last survivors of the Shoa in Europe is less transmitted by the rare survivors until today due to very old age. The impressive unity of the top constitutional powers sets a the path for a far reaching renewal of the acknowledgement of a specific constitutional responsibility to counter extremist tendencies. The speeches by Frank-Walter Steinmeier and Julia Klöckner in the Bundestag (Link in German) were remarkable in explaining in plain language, why we are happy about this liberation also in Germany. The emphasis of the end of pervasive and endless oppression and suffering caused by the Nazi-regime are an essential part of this feeling of liberation. With this commemoration Germany today has become even more a European nation which takes its historical responsibility seriously.

Gedächtniskirche Berlin

The church of commemoration „Gedächtniskirche“ in German has been chosen as the central place of commemoration on Liberation Day in Germany for the ceremony of all religions. All institutions of democracy were represented in addition to the president of the FRG. The church was destroyed, but not completely and the decision to keep the remainders as a permanent warning is visited by thousands of people each year. The public television broadcasts live from the ceremony and some regions of Germany have chosen Liberation Day as a bank holiday following many other European countries. The official end of fighting of the 2nd World War 80 years ago has spurred many events. The need to understand how this could happen and how to guard against extremism to take hold of a country and start a war have preoccupied following generations. The task is not accomplished yet as many people still deny the facts or try to rewrite historical facts with misleading interpretations. The commemoration is well worth a pause to reflect, for example, what were my grandparents doing during these years. Beyond the speeches on this day there are many ways to get involved in carrying the memories to the ones born later.

Ugly duckling revival

Ever since Hans Christian Andersen created the fairy tale of the “ugly duckling” (1843) the story has been adapted to all forms of theatre. The adaptation of the fairy tale to the stage in 2019 and the revival in 2023 at the “Deutsches Theater” in Berlin keeps inspiring people to surpass their restrictions or inhibitions, whatever they may be. This early 19th century fairy tale is a fine piece of the search of identity of a person. As it deals with the difficulty of individuals to find their own identity, the fairy tale deals already with the fitting of an individual into society. Society exercises pressure on individuals to conform to written and unwritten rules, which tend to hold up rules like “one size fits all”. Differentiation and allowing individuals to be different from an established norm becomes a central theme of modernity and even more so in the post-modern world. It is the essence of democratic societies to practice a tolerance of persons being or just wanting to be different. The performance at the “Deutsches Theater” might be a test of your level of tolerance or acceptance of diversity for some, but at the time of rising intolerance in and beyond the U.S. under Trump, such performances are dearly needed to celebrate the rich cultural heritage and achievements of far reaching tolerance. It becomes more evident what we are about to loose (again), if such performances would no longer be possible in a controlled or financially overly restricted world of theatre.

War of drones

The use of drones in warfare is not new in 2025. However, the news reported in the WSJ 2025-05-05 that sea drones from Ukraine with U.S. adapted missiles downed 2 Russian jet fighters made headlines. Compared to jet fighters such drones carrying missiles are a rather cost-effective alternative in warfare. The speed of jets compared to drones made such successful attempts rather unlikely. The information that infrared technology can achieve such identification of targets and guiding missiles is another innovation of the Ukrainian military technology.
Technology is well known to be a game changer in warfare for centuries or across the whole military history. Adaptations of defense strategies will allow Ukraine to hold against the Russian aggression albeit limited financial resources. The defense of air space is one of the crucial elements for Ukraine to deter Russia from moving further ahead through the continuation to increase the costs of war to Russia.
Following a fast moving object and transforming it into a target is an astonishing accomplishment.

More sensors

The technical games that have largely replaced the traditional electrical train and cars of the boomers and older generations shift towards robotics. This has the touch of more future orientation and fun for the young used to gadgets, automation and the beginnings of AI. Therefore, the robots of our children and the ones they assemble in technical games include more sensors. Infrared emission and reception have been present already for some years, but the capture, use and application of sound in children’s games is a bit more recent. In order to assess and understand the far reaching potential of these additional sensors in our homes and environments it is essential to raise awareness through technical games and own experiences or experiments. Educational games are a useful addition to the repertoire of learning for younger generations. Accompanied learning is more likely to keep young people interested in technology and raise awareness for the potential of intrusion into privacy of technology as well. The robots will be more and more part of our daily lives. A better understanding of limitations and potentials will be necessary for all citizens in the 21st century.
