Otto von Guericke

Otto von Guericke was a German scientist and politician. His major scientific achievements were the establishment of the physics of vacuums, the discovery of an experimental method for demonstrating electrostatic repulsion, his advocacy for the reality of "action at a distance" and of "absolute space", he was a spiritual man in the Dionysiac tradition, as were many scientists of the Enlightenment, connected the vacuum of space to an infinite divinity. Von Guericke described this duality "as something that ‘contains all things’ and is ‘more precious than gold...more joyous that the perception of bountiful light’ and ‘comparable to the heavens’." Otto von Guericke was born to a patrician family of Magdeburg. He was tutored until the age of fifteen. In 1617 he began studying philosophy at the Leipzig University. However, in 1620 his studies at Leipzig were disrupted by his father's death, he returned home before continuing his studies at the Academia Julia in Helmstedt and the universities of Jena and Leiden.

It was at Leyden that he first began attending courses on mathematics and fortification engineering. His education was completed by a nine-month Grand Tour to England. On his return to Magdeburg in 1626 he married Margarethe Alemann. Before Margarethe's death in 1645, they had three children together: Anna Catherine, Hans Otto, Jacob Christopher. Anna Catherine and Jacob Christopher both died in infancy. Von Guericke remarried to Dorotha Lentke in 1652. Von Guericke's political career began upon his return to Magdeburg in 1626, he and his family were well-known. He was forced to flee Magdeburg during the Holy Roman Empire's brutal sack of the city during the Thirty Years' War, in which four fifths of the city's population perished; this attack destroyed most of the city as well as von Guericke's personal wealth. Von Guericke returned to Magdeburg in 1631 and, because of his engineering background, led the rebuilding process of the town. After this rebuilding, he became a master brewer to rebuild the town's wealth.

In 1646, he was elected as Magdeburg's Burgomeister, similar to mayor. He remained in this position for more than thirty years until his retirement from office in 1678, after much pressure from younger politicians. During his time in office he met with many kings and emperors. In 1666 Otto von Guericke was given aristocratic status by Emperor Leopold I, giving the "von" title to his name and changing the spelling of his last name from "Gericke" to "Guericke". Otto von Guericke used both his political status and scientific knowledge in tandem to make political gains for his town, his demonstrations of his inventions, such as the air pump and electrostatic generator, were used to impress his audiences and allow for political communications to unfold. He would not explain scientifically how his shows worked leading people to believe in his wizardry, promoting his status as a great leader, his first diplomatic mission on behalf of the city, in September 1642, was to the court of the Elector of Saxony at Dresden to seek some mitigation of the harshness with which the Saxon military commander treated Magdeburg.

In 1648 he represented the city at the treaty delegations following the end of the Thirty Year's War. During another diplomatic mission to Ratisbon in 1654, Guericke used his invention of the air pump to impress those he was meeting and help sway the meeting in his favor, as well as promote his own scientific advancements. Diplomatic missions dangerous as well as tedious, occupied much of his time for the next twenty years. A private scientific life, of which much remains unclear, was developing in parallel. Inspired by Copernican cosmology and the idea of vast, empty space where light could propagate, bodies could move about unhindered, sound cannot be detected, von Guericke set about replicating this phenomena on Earth. Von Guericke first started investigating the concept of a vacuum through the use of fire pumps by pumping water out of wooden barrels. However, he soon figured out that the porosity of wood was allowing unwanted water, filled with dissolved air, to enter; the pressure fluctuations experienced inside the barrel were allowing this encapsulated air to escape: spoiling the vacuum inside.

In 1647 he turned his focus to pumping out enclosed air instead of water to solve this problem. His scientific and diplomatic pursuits intersected when, at the Reichstag in Ratisbon in 1654, he was invited to demonstrate his experiments on the vacuum before the highest dignitaries of the Holy Roman Empire. One of them, the Archbishop Elector Johann Philip von Schonborn, bought von Guericke's apparatus from him and had it sent to his Jesuit College at Wurzburg. One of the professors at the College, Fr. Gaspar Schott, entered into friendly correspondence with von Guericke and thus it was that, at the age of 55, von Guericke's work was first published as an Appendix to a book by Fr. Schott - Mechanica Hydraulico-pneumatica - published in 1657; this book came to the attention of Robert Boyle who, stimulated by it, embarked on his own experiments on air pressure and the vacuum, in 1660 published New Experiments Physico-Mechanical touching the Spring of Air and its Effects. The following year this was translated into Latin and, made aware of it in correspondence with Fr.

Schott, von Guericke acquired a copy. In the decade following the first publication of his own work von

Lake Worth Monster

In Texan folklore, the Lake Worth Monster is a scaly, "part-man, part-goat" creature said to have been seen in Lake Worth, old Alton’s bridge just outside Fort Worth. Reports of sightings by local citizens of "a half-man, half-goat, with fur and scales" in July 1969 led to the belief that a mysterious creature lived in Lake Worth. Newspapers reported the alleged sightings, including one in which the monster landed on a man's car after jumping out of a tree, another in which it threw an automobile tire at a group of people. Newspapers published a photograph purportedly of the creature and locals began driving out to the lake at night to get a look at it. Local police investigated the claims, but found no evidence of the monster in the Lake Worth and Greer Island area. Four decades many, including Allen Plaster, who took the supposed photograph of the creature, suspected that it was a hoax. Reports of the monster ceased when school resumed, which suggests that the incidents were pranks carried out by high school students.

In 2005, a reporter at the Fort Worth Star-Telegram received an anonymous letter from someone claiming to be one of three high school classmates who, in the summer of 1969, "decided to go out to Lake Worth and scare people" using a tinfoil mask. In 2009, Fort Worth, Texas magazine published a report about an unidentified man who said that he had been a perpetrator of the tire-throwing incident. Since 2009, the Fort Worth Nature Center and Refuge has held a Lake Worth Monster Bash each October. Maryland Goatman List of cryptids Pope Lick Monster
