Jan Cornets De Groot
Jan Cornets De Groot or Johan Hugo De Groot Latinized as Janus Grotius (8 March 1554 – 3 May 1640) was a Dutch nobleman and scholar who conducted experiments in physics and explored natural philosophy. Along with Simon Stevin he experimented on the time taken for lead of different weights to fall to the ground to prove Aristotle wrong in the famous Delft tower experiment. De Groot was born at Kraayenburg near Delft, son of Hugo Cornelisz and of Elselinge Van Heemskerck, and was possibly educated in the newly created University of Leiden. He also went to the University of Douai and studied arts and philosophy and following the high positions held by the Cornets de Groot family of Rotterdam who were a part of the Delft ruling class, he became alderman in 1589, a councillor and served as a mayor from 1591 to 1595. He became curator of the Leiden University where he also received a degree in law in 1596, and after 1617 became an advisor to the Count of Hohenlohe. He was involved in th ...

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit (measurement), unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest Positive number, positive integer. It is also sometimes considered the first of the sequence (mathematics), infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally ac ...

Simon Stevin
Simon Stevin (; 1548–1620), sometimes called Stevinus, was a Flemish mathematician, scientist and music theorist. He made various contributions in many areas of science and engineering, both theoretical and practical. He also translated various mathematical terms into Dutch, making it one of the few European languages in which the word for mathematics, '' wiskunde'' ('' wis'' and '' kunde'', i.e., "the knowledge of what is certain"), was not a loanword from Greek but a calque via Latin. He also replaced the word '' chemie'', the Dutch for chemistry, by '' scheikunde'' ("the art of separating"), made in analogy with ''wikt:en:wiskunde#Dutch, wiskunde''. Biography Very little is known with certainty about Simon Stevin's life, and what we know is mostly inferred from other recorded facts.E. J. Dijksterhuis (1970) ''Simon Stevin: Science in the Netherlands around 1600'', The Hague: Martinus Nijhoff Publishers, Dutch original 1943, 's-Gravenhage The exact birth date and the date ...

Delft Tower Experiment
In 1586, scientists Simon Stevin and Jan Cornets de Groot conducted an early scientific experiment on the effects of gravity. The experiment, which established that objects of identical size and different mass fall at the same speed, was conducted by dropping lead balls from the Nieuwe Kerk in the Dutch city of Delft. The experiment is considered a foundational moment in the history of statics, which Stevin's work helped to codify. History In the late 16th century, increasing interest in physics resulted in a number of European scientists conducting experiments into the intricacies of the scientific field. Many of these experiments were—directly or indirectly—presenting a challenge to the laws of physics formulated by Aristotle, whose theory was then the dominant school of thought in Europe. While most contemporaneous scientific experimentation was undertaken by Italian scholars, by the 1580s new ideas on physics had proliferated to the rest of Europe.Asimov, Isaac (1964). ...

Leiden University
Leiden University (abbreviated as ''LEI''; nl, Universiteit Leiden) is a Public university, public research university in Leiden, Netherlands. The university was founded as a Protestant university in 1575 by William the Silent, William, Prince of Orange, as a reward to the city of Leiden for its Siege of Leiden, defence against Spanish attacks during the Eighty Years' War. As the oldest institution of higher education in the Netherlands, it enjoys a reputation across Europe and the world. Known for its historic foundations and emphasis on the social sciences, the university came into particular prominence during the Dutch Golden Age, when scholars from around Europe were attracted to the Dutch Republic due to its climate of intellectual tolerance and Leiden's international reputation. During this time, Leiden became the home to individuals such as René Descartes, Rembrandt, Christiaan Huygens, Hugo Grotius, Baruch Spinoza and Baron d'Holbach. The university has seven academic f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Douai
The University of Douai (french: Université de Douai) ( nl, Universiteit van Dowaai) is a former university in Douai, France. With a medieval heritage of scholarly activities in Douai, the university was established in 1559 and lectures started in 1562. It closed from 1795 to 1808. In 1887, it was transferred as University of Lille 27 km away from Douai.

It played a role in religious doctrines and political controversies in Europe; its s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hohenlohe
The House of Hohenlohe () is a German princely dynasty. It ruled an immediate territory within the Holy Roman Empire which was divided between several branches. The Hohenlohes became imperial counts in 1450. The county was divided numerous times and split into several principalities in the 18th century. In 1806 the Princes of Hohenlohe lost their independence through mediatisation initialized by Napoleon, and their lands became parts of the kingdoms of Bavaria and of Württemberg by the Act of the Confederation of the Rhine (12 July 1806), a confederation of client states of the First French Empire. In 1806 the area of Hohenlohe was 1,760 km² and its estimated population was 108,000. Having lost their Imperial immediacy, the Princes of Hohenlohe still kept their private possessions. Until the German Revolution of 1918–19, just as other mediatized families, they also retained important political privileges. They were considered equal by birth (''Ebenbürtigkeit'') to t ...

Euclid
Euclid (; grc-gre, Wikt:Εὐκλείδης, Εὐκλείδης; BC) was an ancient Greek mathematician active as a geometer and logician. Considered the "father of geometry", he is chiefly known for the ''Euclid's Elements, Elements'' treatise, which established the foundations of geometry that largely dominated the field until the early 19th century. His system, now referred to as Euclidean geometry, involved new innovations in combination with a synthesis of theories from earlier Greek mathematicians, including Eudoxus of Cnidus, Hippocrates of Chios, Thales and Theaetetus (mathematician), Theaetetus. With Archimedes and Apollonius of Perga, Euclid is generally considered among the greatest mathematicians of antiquity, and one of the most influential in the history of mathematics. Very little is known of Euclid's life, and most information comes from the philosophers Proclus and Pappus of Alexandria many centuries later. Until the early Renaissance he was often mistaken f ...

Archimedes
Archimedes of Syracuse (;; ) was a Greek mathematician, physicist, engineer, astronomer, and inventor from the ancient city of Syracuse in Sicily. Although few details of his life are known, he is regarded as one of the leading scientists in classical antiquity. Considered the greatest mathematician of ancient history, and one of the greatest of all time,* * * * * * * * * * Archimedes anticipated modern calculus and analysis by applying the concept of the infinitely small and the method of exhaustion to derive and rigorously prove a range of geometrical theorems. These include the area of a circle, the surface area and volume of a sphere, the area of an ellipse, the area under a parabola, the volume of a segment of a paraboloid of revolution, the volume of a segment of a hyperboloid of revolution, and the area of a spiral.
