A German chapbook published around is the oldest known extant publication about the folk hero a first edition of c. The character may have been based on a historical person. He plays practical jokes on his contemporaries, at every turn exposing vices. His life is set in the first half of the 14th century, and the final chapters of the chapbook describe his death from the plague of It has been suggested that the name is in fact a pun on a Low German phrase that translates as "wipe-arse". Modern retellings of the Eulenspiegel story have been published since the latter 19th century.

He introduced much of modern mathematical terminology and notation , including the notion of a mathematical function. Euler is held to be one of the greatest mathematicians in history and the greatest of the 18th century. Several great mathematicians who produced their work after Euler's death have recognised his importance in the field as shown by quotes attributed to many of them: Pierre-Simon Laplace expressed Euler's influence on mathematics by stating, "Read Euler, read Euler, he is the master of us all. He also became famous for, among many other accomplishments, providing a solution to several unsolved problems in number theory and analysis, including the Basel problem , which had remained unsolved for years. The Basel problem consists of finding the sum of the reciprocals of the squares of the natural numbers. Euler has also been credited for discovering that the sum of the numbers of vertices and faces minus the number of edges of a polyhedron equals 2, a number now commonly known as the Euler characteristic. In the field of physics, Euler reformulated Newton 's laws of physics into new laws in his two-volume work Mechanica to better explain the motion of rigid bodies. He also made substantial contributions to the study of elastic deformations of solid objects. From a young age, Euler received schooling in mathematics from his father, who had taken courses from Jacob Bernoulli some years earlier at the University of Basel. Around the age of eight, Euler was sent to live at his maternal grandmother's house and enrolled in the Latin school in Basel. In addition, he received private tutoring from Johannes Burckhardt, a young theologian with a keen interest in mathematics. In , at thirteen years of age, Euler enrolled at the University of Basel. Johann Bernoulli and Euler soon got to know each other better. Euler described Bernoulli in his autobiography: [18]. It was during this time that Euler, backed by Bernoulli, obtained his father's consent to become a mathematician instead of a pastor.

Hreblay : Noctuidae Europaeae, Volume 4. In the Americas, rather, an expansion of immigrant lineages of ancestral typical owls occurred.

Die beiden deutschen Begriffe haben sich lautmalerisch aus den Rufen der Eulen entwickelt. Eulen besitzen eine sehr typische Gestalt. Bei der Schleiereule z. Die Ausnahme davon stellen die Fischeulen und Fischuhus dar, die sich auf Fische als Nahrungstiere spezialisiert haben. Die Normalstellung ausgewachsener Eulen ist dabei zygodactyl , also mit zwei nach vorn und zwei nach hinten weisenden Zehen. Eulenarten sind weltweit mit Ausnahme der Antarktis sowie einzelner Inseln verbreitet. Die meisten Eulen sind nachtaktiv. Sie jagen in der Nacht und schlafen am Tag. Ausnahmen sind beispielsweise die tagaktive Schnee-Eule , die Sperbereule , die Sumpfohreule oder der oft auch am Tag aktive Sperlingskauz. Eulen sind vor allem auf nachtaktive Beutetiere spezialisiert.

Euglena is a genus of single cell flagellate eukaryotes. It is the best known and most widely studied member of the class Euglenoidea , a diverse group containing some 54 genera and at least species. They are often abundant in quiet inland waters where they may bloom in numbers sufficient to color the surface of ponds and ditches green E. The species Euglena gracilis has been used extensively in the laboratory as a model organism.

Hadeninae II. Archived from the original on 13 August Euler introduced and popularized several notational conventions through his numerous and widely circulated textbooks. The facial disk also acts to direct sound into the ears, and a downward-facing, sharply triangular beak minimizes sound reflection away from the face. JSTOR I wanted to have a water jet in my garden: Euler calculated the force of the wheels necessary to raise the water to a reservoir, from where it should fall back through channels, finally spurting out in Sanssouci. Each Euler curve divides the plane into two regions or "zones": the interior, which symbolically represents the elements of the set, and the exterior, which represents all elements that are not members of the set. Mathematics in Berlin. Asymmetrical ear placement on the skull allows the owl to pinpoint the location of its prey. Meleagridinae turkeys Perdicinae Phasianinae pheasants and relatives Tetraoninae. In the town of Damme, Belgium, there is also a museum honoring him, and there is a fountain and statue featuring Till Eulenspiegel in the Marktplatz of Magdeburg, capital city of Sachsen-Anhalt.

Analysis by its history 1st ed. An owl's sharp beak and powerful talons allow it to kill its prey before swallowing it whole if it is not too big. My mill was carried out geometrically and could not raise a mouthful of water closer than fifty paces to the reservoir. Mitteilungen der Deutschen Mathematiker-Vereinigung.

Gaviiformes loons or divers Sphenisciformes penguins Procellariiformes albatrosses and petrels Ciconiiformes storks Suliformes cormorants and relatives Pelecaniformes pelicans and relatives. According to the Apache and Seminole tribes, hearing owls hooting is considered the subject of numerous " bogeyman " stories told to warn children to remain indoors at night or not to cry too much, otherwise the owl may carry them away. OCLC Wikimedia Commons Wikiquote Wikisource. The stone is inscribed in Low German, as follows:. He gives the year as the date when he originally began to collect the tales, stressing the difficulty of the project and how he wanted to abandon it several times, saying that he is now publishing it after all to "lighten the mood in hard times". There are several suggestions as to the author of the chapbook, none of which has gained mainstream acceptance. In the same year, the OWG published the results of detailed investigations conducted from to into the habitat requirements of the little owl in Germany.
