Jean de Rignies, a French civil engineer, has left us a very special legacy. It consists of a notebook filled with handwritten notes dictated to him by an extraterrestrial UFO commander named Lilor. What makes these notes from Jean de Rignies particularly remarkable is that they largely contain mathematical and physical formulas and explanations that go far beyond our current knowledge. These texts have now been fully analyzed for the first time by mathematician and electrical engineer Klaus Piontzik, who presents the results of his work in this book. He discovered that these notes are strikingly related to the 'Letters from the Planet UMMO.' He managed to organize the material in such a way that a clear thread emerges, revealing the structure of the extraterrestrial worldview in a comprehensible manner. Two major themes have crystallized: one encompasses the physical, technological, and cosmological worldview of the aliens, while the other addresses their spiritual and cosmological perspective. The material can also be seen as a key to understanding the aliens' worldview. Thanks to the insights gained from Jean de Rignies' notes and the UMMO letters, new perspectives will open up for humanity. It is now essential to apply the knowledge gained from the Ummites' foresight regarding current and future issues for the benefit of mankind.
