Johannes Gessner
Johannes Gessner (18 March 1709 – 6 May 1790) was a Swiss mathematician, physicist, botanist, mineralogist and physician. He is seen as the founder of the "Naturforschende Gesellschaft in Zürich". Gessner was born and died in Zürich, where he trained under the physician Johannes von Muralt. He moved to Basel to study medicine, continuing his studies in 1726 and 1727 at the University of Leiden. There he became friendly with Albrecht von Haller, with whom he made a grand tour to Paris to finish their medical studies. There he wrote his diary, later published as ''Pariser Tagebuch''. The two friends in 1728 studied mathematics under Johann Bernoulli and travelled through Switzerland. Gessner became a doctor in Basel in 1730, but soon changed to a scientific career. In 1733 he became a mathematics professor and in 1738 began to teach physics in Zürich. Gessner influenced many Swiss students, such as Johann Heinrich Rahn and Johann Georg Sulzer. Gessner produced publicati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Georg Sulzer
Johann Georg Sulzer (; 16 October 1720 in Winterthur – 27 February 1779 in Berlin) was a Swiss professor of Mathematics, who later on moved on to the field of electricity. He was a Wolffian philosopher and director of the philosophical section of the Berlin Academy of Sciences, and translator of David Hume's '' An Enquiry Concerning the Principles of Morals'' into German in 1755. Sulzer is best known as the subject of an anecdote in the history of the development of the battery Battery most often refers to: * Electric battery, a device that provides electrical power * Battery (crime), a crime involving unlawful physical contact Battery may also refer to: Energy source *Automotive battery, a device to provide power t .... In 1752, Sulzer happened to put the tip of his tongue between pieces of two different metals whose edges were in contact. He exclaimed, "a pungent sensation, reminds me of the taste of green vitriol when I placed my tongue between these metals." He thoug ...

18th-century Swiss Physicists
The 18th century lasted from January 1, 1701 ( MDCCI) to December 31, 1800 ( MDCCC). During the 18th century, elements of Enlightenment thinking culminated in the American, French, and Haitian Revolutions. During the century, slave trading and human trafficking expanded across the shores of the Atlantic, while declining in Russia, China, and Korea. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures, including the structures and beliefs that supported slavery. The Industrial Revolution began during mid-century, leading to radical changes in human society and the environment. Western historians have occasionally defined the 18th century otherwise for the purposes of their work. For example, the "short" 18th century may be defined as 1715–1789, denoting the period of time between the death of Louis XIV of France and the start of the French Revolution, with an emphasis on directly interconnected events.

Johann Heinrich Rahn
Johann Rahn (Latinised form Rhonius) (10 March 1622 – 25 May 1676) was a Swiss mathematician who is credited with the first use of the division sign, ÷ (a repurposed obelus variant) and the therefore sign, ∴. The symbols were used in ''Teutsche Algebra'', published in 1659. John Pell collaborated with Rahn in this book, which contains an example of the Pell equation. It is uncertain whether Rahn or Pell was responsible for introducing the symbols. Books Teutsche Algebra- Johann H. Rahn Literature *R.

Johann Bernoulli
Johann Bernoulli (also known as Jean or John; – 1 January 1748) was a Swiss mathematician and was one of the many prominent mathematicians in the Bernoulli family. He is known for his contributions to infinitesimal calculus and educating Leonhard Euler in the pupil's youth. Biography Early life Johann was born in Basel, the son of Nicolaus Bernoulli, an apothecary, and his wife, Margarethe Schongauer, and began studying medicine at University of Basel. His father desired that he study business so that he might take over the family spice trade, but Johann Bernoulli did not like business and convinced his father to allow him to study medicine instead. Johann Bernoulli began studying mathematics on the side with his older brother Jacob Bernoulli. Throughout Johann Bernoulli's education at Basel University the Bernoulli brothers worked together spending much of their time studying the newly discovered infinitesimal calculus. They were among the first mathematicians to not only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
