The moon accompanied the earth long before the emergence of life on earth. For a long time it was the only source of light at night and has always inspired the imagination of mankind with its changing appearance. The long common history of the moon and the earth is discussed, its structure and its influence on the earth and living beings. Results of the numerous lunar expeditions are presented as well as currently planned lunar missions. Some of the most prominent structures of the moon can be seen and there are tips on how to observe the lunar surface with simple tools.

Dr. Mario Harz, Philosopher

Besides the negation of chords we also have a variant of the conjunction of chords. With the help of the basic notions of negation and conjunction we can define all other logical functors like implication, alternative of classical propositional logic etc. and we can relate these functors to chords. This gives us the creative possibility to interpret propositional logic systems (axiom systems) musically and make them sound. In 2012, the first axiom system for propositional logic, presented by Gottlob Frege in 1879 with his Begriffsschrift, was set to music. The lecture introduces the methodology of the logical composition technique and concludes by presenting the work as a musical treat for the audience.

Dr. Jana Kirschner, Chair Therapy Sciences I

Currently, approximately 300,000 prosthetic fittings are performed in the lower extremity in Germany. In this lecture, indications and contraindications of a prosthetic treatment of a hip arthrosis patient will be pointed out. Currently, this surgical treatment option is considered the gold standard for reducing pain and improving joint mobility. Surgical treatment options and their post-treatment guidelines will be presented, as well as the presentation of results based on assessments.

Online Ring Lecture l 4 - 6 p.m.

Prof. Dr. Hans Friesen, Former field of study Philosophy of Culture

In 1996, the US-American political scientist Samuel Huntington surprised us in his book Clash of Civilizations with a very catchy but nevertheless grossly simplifying world formula. This formula states that after the end of the Cold War it would no longer be "political ideologies" but "cultures" that would determine the order of the world. Although this thesis was massively criticized by scholars at an early stage, it has nevertheless become an integral part of public discussion worldwide. But the more conscientious interpretation of history showed that although the world since World War II with its bipolar structure has changed from the 1980s to one with a multipolar or multicultural structure, this structure is in motion and continues to change. It points to 'cultural patterns' associated with our different views of humanity, each pointing to unresolved justice problems in international relations. In this perspective, nations remain major players in world affairs, albeit weakened by economic and technological globalization, and will act in various coalitions, both economic and military, to maintain or increase power and influence. Now, one cannot conclude from this view only unilaterally that the conflicts threatening in the future will occur above all at the numerous "front lines" or "fault lines" of the cultural groups, as Huntington meant, because some critics assume at the same time that this can be countered if the West tries to prevent this dangerous struggle at an early stage with a targeted or clever "dialogue of cultures". However, this cannot succeed if one imagines this dialogue, as some political hardliners understand it today, as strategic negotiations to achieve good relations with, for example, Korea, Japan and Australia, which is claimed in order to specifically assert the "interests of the West" both in the Near and Middle East and above all vis-à-vis that economically and militarily rapidly rising Confucian-Communist "Middle Kingdom" in the Far East.

Prof. Dr. Julia von Maltzahn, Chair of Stem Cell Biology of Aging.

Skeletal muscle is one of the tissues with the highest capacity for regeneration. This is needed, for example, after an injury. Regeneration of skeletal muscle is driven by muscle stem cells. However, as we age, the ability of skeletal muscle to regenerate decreases. In this lecture, we will look at the causes of poorer skeletal muscle regeneration and what intervention options are available in this regard based on current research examples.

Stefan Palm, East German Rose Garden Forst

Climate change" is on everyone's lips and is also occupying the "green"
sector: gardeners, those responsible for green spaces and parks, landscape architects, to name but a few: What effects are already "everyday life" and how do we deal with it - the East German Rose Garden has been involved for many years in the "General German Rose Novelty Testing" and thus in the sighting of new rose varieties. What contribution do plant sightings make in variety development for the gardens of the future?

Dr. Manuel Peters, Chair of Interculturalism

In this contribution, racism is presented as a comprehensive social phenomenon, as a power-knowledge-complex that has inscribed itself in a sustainable way into the various socio-economic configurations of modernity and serves(s) the legitimation of exploitation. Selected examples from research will be used to illustrate and discuss the significance of the critique of racism for research and the analysis of current (global) social processes.

Toni Schneidereit, Chair of Applied Mathematics

What do youth language and object recognition have in common? At first glance, not much, except the term "yolo". In this talk, find out why yolo (in AI-based object recognition) is "just cool", what's behind it, and where the strengths/weaknesses lie.

Prof. Dr. Kay Hempel, ABWL, in particular Financial Economics and Financial Services

In the Federal Republic of Germany, the number of commercial banks has been continuously decreasing for decades due to mergers. At the same time, the "3-pillar principle" consisting of private credit institutions, the public banking sector and the cooperative sector is still characteristic of the German banking system. The mortgage banks and the Landesbanken have undergone some remarkable changes in the last decade. Moreover, some changes in the ownership structure of private credit institutions have received little public attention. The current high inflation rate in the euro zone has led to a change in the ECB's monetary policy, after interest rates had always been on a downward trend for a decade. The "return of the interest rate" is associated with effects on bond prices and thus also has effects on funded pensions.

Dr. Steffen Braune, Chair Molecular Cell Biology

Arthrospira platensis (Spirulina) is a blue-green alga and has a high content of nutritious ingredients such as proteins, vitamins and minerals. It has health-promoting properties - helping to lower blood pressure and blood sugar, for example - making it superior overall to many everyday human foods. We show how spirulina can contribute to a healthy diet while helping to reduce_CO2 from the atmosphere.

Public lecture series l 4 - 6 p.m.

Prof.in Dr.in Heike Radvan, Chair Methods and Theories of Social Work with a focus on Community Work and Prevention of Right-Wing Extremism

Language changes. From a historical perspective, this is not a new phenomenon. Current approaches, such as a gender-reflective and discrimination-critical use of language, aim to reflect on our speech in terms of what effect it has: Who is being addressed? Who is meant? How is it possible to speak in a respectful way that excludes experiences of discrimination and possible violations? Which approaches open up common learning processes and paths towards a most inclusive, solidary and dialogue-oriented coexistence? In the lecture, background knowledge on the relevant topics will be conveyed as well as thinking in the direction of practice.

Prof. Dr. Christian Abendroth, Chair of Circular Economy

That elements in science are not always easy to grasp or sometimes assume mixed states, we know since Werner Heisenberg and Schrödinger's cat. In the circular economy, too, we work with the problem that things are not always so clear and sometimes difficult to grasp. This starts with the term "circular economy" and continues into many products with the following question: Is the product really sustainable? In the 90-minute presentation, the vagueness of the circular economy is addressed at the beginning. In the further course, current research topics of the chair Circular Economy are briefly presented. This mainly concerns biological methods of waste treatment.

Bartosz Lysakowski, Tierpark Cottbus

Wild animals know no borders, laws and cultural differences do. A short story why Little Red Riding Hood lies and Poland as a country is only half as wild as people in Germany like to believe. A journey through fake news thickets with guard dogs, city ecos and technical literature.

Dr. Florian Kohn, Federal Office for Radiation Protection (BfS)

The expansion and reconstruction of existing power grids is very present in the media due to the planned energy turnaround. The Federal Office for Radiation Protection (BfS) is researching and evaluating whether the low-frequency electric and magnetic fields of power lines pose risks to humans and the environment. The lecture will deal with the physical basics and biological effects of these low-frequency fields. Subsequently, further topics such as limit values, risk, and risk assessment will be discussed. Questions such as "How to define risk" or "How do underground cables and overhead lines differ" will be discussed.
