Sir Isaac Newton: Master and Warden of the Mint
Sir Isaac Newton (1643-1727) was more than the most brilliant man of his time. He invented the physics and the mathematics that made possible the industrial age and the electronic age. He was an accomplished lawyer, a prosecutor for the state, and later an effective political administrator. His work in theology is unappreciated today as is his skillful and artistic craftsmanship. He served in Parliament. He was president of the Royal Society. For 30 years, he was Warden and Master of the Royal Mint.

Introducing Newton's Mint-Related Papers
In 1696, at the age of 53, Newton was appointed Warden (i.e. chief officer) of the Royal Mint, which was at this date housed in the Tower of London. Some biographers have seen this as a tragic waste of an extraordinary intellect on a mundane bureaucratic job. However, it is clear that Newton had been actively seeking such an appointment for several years.

Royal Society
La Royal Society, anche se a contributo volontario, è ritenuta l'accademia nazionale inglese delle scienze. Fondata il 28 novembre 1660 è una delle accademie più antiche attualmente esistenti.

Brief history of the Royal Society
The origins of the Royal Society lie in an "invisible college" of natural philosophers who began meeting in the mid-1640s to discuss the ideas of Francis Bacon. Its official foundation date is 28 November 1660, when 12 of them met at Gresham College after a lecture by Christopher Wren, the Gresham Professor of Astronomy, and decided to found 'a Colledge for the Promoting of Physico-Mathematicall Experimentall Learning'. This group included Wren himself, Robert Boyle, John Wilkins, Sir Robert Moray, and William, Viscount Brouncker.

Royal Society
La Royal Society of London for the Improvement of Natural Knowledge de Londres, connue sous le nom de Royal Society, ou Société royale de Londres, est une institution destinée à la promotion des sciences, fondée en 1660. Elle est l’équivalent de l’Académie des sciences en France. La Royal Irish Academy, fondée en 1782, lui est affiliée.

Royal Society
La Royal Society of London for Improving Natural Knowledge es la más antigua sociedad científica del Reino Unido y una de las más antiguas de Europa. Aunque se suele considerar el año 1660 como el de su fundación, años antes ya existía un grupo de científicos que se reunía con cierta periodicidad. Mantiene estrechas relaciones con la Academia Real Irlandesa fundada en 1782, mientras que la Real Sociedad de Edimburgo, fundada en 1783, se mantiene como una institución escocesa independiente. A pesar de ser una institución privada e independiente hace las veces de Academia Nacional de Ciencias en Reino Unido y es miembro del Consejo Científico Británico formado en 2000.

Legge di Newton del raffreddamento (o riscaldamento)
La procedura per ricavare la legge di Newton è descritta in molti testi di fisica generale, qui la richiamiamo brevemente partendo da alcuni i concetti basilari che regolano gli scambi di calore.

Legge del Raffreddamento di Newton
L'obiettivo di questo esperimento è studiare l'andamento temporale della temperatura di un oggetto che si raffredda e trovare un modello matematico che lo descriva.

Newton's law of cooling
We have examined the behaviour of two simple differential equations so far, one for population growth, and one for the radioactive decay of a substance. The methods we have developed are actually useful for many other interesting problems, and can help us to make predictions about other systems that, at first sight, do not seem at all related. We will find that the common thread in all these systems is the simple differential equation of the form

Loi de loi newton :refroidissement d'un corps
Une loi de Newton stipule que la vitesse de refroidissement d'un corps reste proportionnelle à la différence entre la température de ce corps à l'instant t et la température constante de l'air ambiant (le coefficient de proportionnalité dépend essentiellement de la surface de contact entre le corps et son milieu, et on considérera ici que ce coefficient est constant).

Ley del enfriamiento de Newton
En esta página, se simula una experiencia de laboratorio poco usual, la medida del calor específico de un cuerpo metálico empleando la ley del enfriamiento de Newton. Para ello, tenemos que conocer el calor específico de un cuerpo de las misma forma y dimensiones que tomamos como referencia.

Newton's Optical Papers
In the mid-1660s, Newton became so fascinated by the nature of light and vision that he seriously risked blinding himself by staring at the sun, and by poking the sides of his eyeball with a 'bodkin' (i.e. a small knife), in order to assess how such activities would affect his sight. These experiments, together with a number of rather more sensible ones, led him to formulate revolutionary theories about the nature of the spectrum and the refraction of light.

Opticks
Opticks is a book written by English physicist Isaac Newton that was released to the public in 1704. It is about optics and the refraction of light, and is considered one of the great works of science in history. Opticks was Newton's second major book on physical science. Even if he had not made his better-known discoveries concerning gravity and the invention of the calculus, Opticks would have given him the reputation as one of the greatest scientists of his time.

Opticks
Opticks (o “Un tratado de las reflecciones, refracciones, inflecciones y colores de la luz”) es el resumen de fragmentos del Libro Primero, Segundo y Tercero de Óptica de Isaac Newton. El libro comienza con una pequeña introducción en donde nos explica someramente el contenido del tratado y probará propiedades de la luz con métodos experimentales.
