  1. Robert Hooke, (born July 18 [July 28, New Style], 1635, Freshwater, Isle of Wight, England—died March 3, 1703, London), English physicist who discovered the law of elasticity, known as Hooke’s law, and who did research in a remarkable variety of fields. In 1655 Hooke was employed by Robert Boyle to construct the Boylean air pump. Five years later, Hooke discovered his law of elasticity ...

  2. Robert Boyle (Waterford, 25 de enero de 1627-Londres, 31 de diciembre de 1691) [1] fue un filósofo natural, químico, físico e inventor anglo-irlandés. También fue un prominente teólogo cristiano .

  3. Fue formulada en 1660 por el científico británico Robert Hooke, contemporáneo del célebre Isaac Newton. El precepto teórico de esta ley es que el desplazamiento o la deformación sufrida por un objeto sometido a una fuerza , será directamente proporcional a la fuerza deformante o a la carga.

    Robert Hooke's microscope was a recreation of Anton van Leeuwenhoek's microscope in the 17th century, except his was 300x magnification. The discovery of the cell was made possible through the invention of the microscope. In the first century BC, Romans were able to make glass. They discovered that objects appeared to be larger under the glass.

  5. En physique, la loi de Hooke modélise le comportement des solides élastiques soumis à des contraintes. Elle stipule que la déformation élastique est une fonction linéaire des contraintes. Sous sa forme la plus simple, elle relie l'allongement (d'un ressort , par exemple) à la force appliquée.

  6. 05/11/2007 · 1655 – Hooke described ‘cells’ in cork. 1674 – Leeuwenhoek discovered protozoa. He saw bacteria some 9 years later. 1833 – Brown descibed the cell nucleus in cells of the orchid. 1838 – Schleiden and Schwann proposed cell theory. 1840 – Albrecht von Roelliker realized that sperm cells and egg cells are also cells.

  7. Hooke’s law, law of elasticity discovered by the English scientist Robert Hooke in 1660, which states that, for relatively small deformations of an object, the displacement or size of the deformation is directly proportional to the deforming force or load. Under these conditions the object returns to its original shape and size upon removal of the load. Elastic behaviour of solids according ...
