The article "Issue 32(1)" in the Communications of the German Mathematical Society (DMV) covers various topics such as the DMV Student Conference 2024 in Ilmenau, the significance of mathematics in museums, job opportunities for mathematics graduates, and the name of the DMV. The president of the DMV emphasizes the need to attract more and younger members and to make greater efforts towards women and diversity. It also reports on the discussion about renaming the DMV, for which suggestions from members are being collected. The 2023 PISA study shows that the average mathematical and reading competencies of adolescents in many OECD countries have declined compared to the previous study in 2018. Scientific competence has also decreased. In Germany, the performance losses in all three areas are above average. The reasons for the deterioration are mainly attributed to the effects of the COVID-19 pandemic, as well as language difficulties, interest, and motivation. The exhibition "From Newton to Einstein - a journey through space and time" was developed at the Max Planck Institute for Gravitational Physics in Potsdam and is now on display in Tübingen. The award winner Carla Cederbaum has also developed other projects, such as a book on mathematical magic tricks and the publication series "Oberwolfach-Snapshots of Modern Mathematics". Mathematicians Carolin Mehlmann and Thomas Richter from the University of Magdeburg participated in an expedition of the Polarstern to the Arctic Ocean to calibrate a new hybrid sea ice model. The hybrid sea ice model combines particle and continuum methods to better resolve the different sea ice regimes on different local scales. The text deals with the deformation theorem in differential geometry. It is shown that a manifold with boundary possesses a metric with certain properties if the double of the manifold carries such a metric. The question of whether the converse of this statement holds is also raised. The text deals with hypothesis testing and the problem of multiple error probability. Various methods for solving this problem are presented, including the Bonferroni correction and the development of better methods taking into account the dependency structure of the tests. It also addresses pseudoline arrangements, which have connections to combinatorics, geometry, and computer science. The text deals with various mathematical topics, including sorting networks, pseudoline arrangements, Rubik's cube, the PISA study, calculating machines, student studies, Felix Klein, and international cooperation in mathematics. Various concepts and applications are explained, such as the creation of sorting networks from pseudoline arrangements, the use of Markov chains to generate random pseudoline arrangements, and the development of calculation aids and calculating machines. The importance of student studies and international cooperation in mathematics is also emphasized. The text provides an insight into various mathematical topics and their applications.

The Ellsberg Paradox, discovered by Daniel Ellsberg, is an important paradox in economic theory that raises the question of how people estimate probabilities. It refers to the decision between red and black balls in an urn and shows that people who answer "red" to the first question and "black or yellow" to the second question contradict themselves. Daniel Ellsberg became known for the publication of the Pentagon Papers and was charged with espionage and treason, but the trial was declared flawed due to misconduct by the prosecution and the government. Ellsberg also showed that people violate the axiom of independence of irrelevant alternatives and that subjective probabilities cannot be added. The author of the article, George Szpiro, is a Swiss-Israeli journalist and author. [Extracted from the article]

In addition, the winners of the Breakthrough Prize and the New Horizons Prize, as well as the awarding of the Hector Science Prize and funding by the European Research Council, are mentioned. Valentin Blomer receives an ERC Advanced Grant of two million euros for his research on number-theoretical objects and automorphic forms. The project aims to achieve progress and solutions for three unsolved mathematical conjectures. Georg Oberdieck examines in his project "Correspondences in enumerative geometry: Hilbert schemes, K3 surfaces and modular forms" the enumerative geometry of algebraic surfaces, especially K3 surfaces. The project is supported by an ERC Starting Grant of 1.5 million euros. The Heidelberg Laureate Forum Foundation celebrates its 10th anniversary with various events, including the 10th Heidelberg Laureate Forum in September. A group of mathematicians of Ukrainian origin is founding the International Center for Mathematics in Ukraine to promote top-level mathematics in the country. The competition "Jugend forscht" has begun, in which young researchers present their projects. A team of young researchers has developed a new warning device for lathes that indicates when a workpiece has been clamped incorrectly. This is one of many examples of the diversity of research projects in "Jugend forscht" and "Schüler experimentieren". The winners of the regional competitions qualify for the state competitions, which begin in March 2023. The national final of Jugend forscht will take place in Bremen in May 2023. The Mathematical Research Institute Oberwolfach invites doctoral students and postdocs to apply for seminars in 2023. These seminars are organized by leading experts in the respective field and are aimed at promising young scientists from all over the world. Lena Lattwein, a talented football player, also has exceptional mathematical abilities. She has completed her bachelor's degree in mathematical economics and is now focusing on her career as a professional football player. The entry in the Tilings Encyclopedia deals with the kite and dart Penrose tiling. These tilings are non-periodic but exhibit a high degree of global order. By suitable markings, the stones can generate exclusively non-periodic tilings. The tiling can be generated by projecting points of the five-dimensional lattice Z5 onto the plane. The Penrose tilings are connected to the discovery of quasicrystals and have led to a wave of research in the field. [Extracted from the article]

The article "Logbook Mathematics" deals with mathematical jokes and April Fools' jokes. It is mentioned that Martin Gardner made some April Fools' jokes in April 1975, such as the claim that the theory of relativity had been disproven. The number eπ√163 is now referred to as the Ramanujan constant. Robert J. Scherrer discusses in a paper the possibility that the values of π, e, γ, φ, and whole numbers could change over time. Other mathematical April Fools' jokes are also mentioned, such as a decomposition of the sphere into hexagons. There is a reference to an April Fools' joke about Fermat's conjecture, in which a well-known mathematician announced a counterproof. Another mathematician spread an April Fools' joke about the Riemann hypothesis through a mailing list. There is also a report about a fake article from Der Postillon, which claimed that German elementary school students do not master infinitesimal calculus. The Titanic and the NachDenkSeiten also published satirical articles about mathematical concepts and the Ukraine crisis. [Extracted from the article]

The article "President's Greeting" reports on the position paper on equal opportunities and diversity of the German Mathematical Society (DMV). The DMV presidency emphasizes the importance of a diverse, respectful, and inclusive community. It is mentioned that the discussion about a possible renaming of the DMV has resurfaced, but no name change has taken place so far. The presidency has established a specialist group for gender, diversity, and sustainability in mathematics and proposes a participatory process to shape the discussion about the name of the DMV. Furthermore, reference is made to a paper adopted by various mathematical and scientific societies, condemning antidemocratic and nationalist approaches in Germany. It is emphasized that science requires openness, international cooperation, democracy, and the rule of law. [Extracted from the article]
