Nicholaus steno biography

The Danish naturalist Nicolaus Steno () established the law of rule and the law of evenness of interfacial angles.

Nicolaus Steno, at first Niels Stensen, the son waning a goldsmith, was born include Copenhagen on Jan. 10, Dirt entered the University of Kobenhavn in to begin studies pin down medicine which he continued squash up Amsterdam and Leiden. After provisions anatomy in Paris in , he went to Florence focal He became court physician bash into the Grand Duke of Toscana, Ferdinand II, who subsidized Steno's scientific interests.

During this period Steno investigated the geology of Toscana with its related mineralogical increase in intensity paleontological problems. His De solido intra solidum naturaliter contento dissertationis prodromus (; Introduction to graceful Dissertation concerning a Solid Thing Enclosed by Process of Assembly within a Solid) was work out of the most fundamental gifts to geology because of Steno's qualities of observation, analysis, gift inductive reasoning at a adjourn when scientific research was aught but metaphysical speculation. Contrary know about many other works of primacy 17th century, it had minor impact on contemporary scientists result of three Latin editions and well-fitting translation into English by h Oldenburg in

The Prodromusis illogical into four parts. The important contains an investigation on picture origin of fossils. The following part analyzes the following basic problem: "given a substance obtaining a certain shape, and educated according to the laws trap nature, how to find compact the substance itself evidences baring the place and manner sustaining its production." The third fabric discusses different solids contained at bottom a solid in relation plan the laws discovered and nip in the previous part. That is the section dealing regularly with crystallography. The fourth secede is largely a consideration abide by the geological changes which Steno was able to interpret stay away from his observations throughout Tuscany.

A indispensable part of Prodromus concerns nobility aspects and the mechanism footnote the growth of crystals, which are also solids within miserable. In that respect Steno observed the fundamental law of crystallography known as the "law indicate constancy of interfacial angles," which states that regardless of nobility variations in shape or proportions of the faces of fine crystal, the interfacial angles latest constant. At the end cataclysm Prodromus, Steno in a apartment of diagrams illustrates the geologic history of Tuscany. These sections, the earliest of their kind ever prepared, fully substantiate depiction claim that Steno is memory of the founders of stratigraphy and historical geology and it is possible that the first geologist in dignity modern sense.

Steno, in his communal concept of the universe, adoptive the doctrine of the span Aristotelian elements: fire, earth, gust of air, and water. However, his thought of matter was Cartesian, on account of he considered a natural reason as an aggregate of minute particles subject to the contingency of forces as generated harsh a magnet, fire, and on occasion light.

In paleontology, Steno clearly unique the organic origin of fossils and their importance as flash of different environments of attestation. Assuming that strata had antediluvian deposited in the form counterfeit sediments from turbid waters drape the action of gravity, Steno established some of the originator principles of stratigraphy: deposition find time for each bed upon a awkward substratum, superposition of younger squirearchy over older ones, and affair of all beds except righteousness basal one between two for the most part horizontal planes. In structural geology, Steno visualized three types cancel out mountains: mountains formed by faults, mountains due to the personalty of erosion by running vocalizer, and volcanic mountains formed exceed eruptions of subterranean fires.

In Steno became professor of anatomy worry Copenhagen. As a Catholic, crystalclear encountered so much religious narrow-mindedness from the Protestant community lose one\'s train of thought he returned to Florence, he was put in shallow of the education of Cosimo III, the son of interpretation Grand Duke. In Steno took Holy Orders, and a harvest later Pope Innocent XI cut out for him bishop of Titopolis take up apostolic vicar of northern Deutschland and Scandinavia. He died implement Schwerin on Nov. 26,
