Edme Mariotte, a Roman Catholic priest and a founding member of l'Académie des sciences de Paris in 1666, is mainly remembered as the first scientist to discover the blind spot, known as Mariotte's Spot, in visual fields. His extensive work on optics and color perception is less well remembered. In addition, he made other important discoveries in different areas of science such as physics, mechanics, hydraulics, optics, plant physiology, meteorology, surveying, and research methodology. Mariotte was an active experimenter whose experimental principles separated science from metaphysics. His work was known to many of his fellow great scientists of his day, including Newton and Descartes, and his lengthy correspondence was a pioneering form of scientific international cooperation. Mariotte's observations, experiments, and demonstration of the blind spot led to a lively debate in the scientific community as to its explanation. Although he falsely assumed that it was the choroid, not the retina, that was the site of perception in the eye, he may be considered as a forerunner of neuro-ophthalmology due to his experiments and interest in the fundus.

Between the 1670s and 1680s, the French King Louis XIV's evolving vision for the fountains of the Versailles gardens challenged the knowledge and abilities of his hydraulic engineers. The supplying of water to Versailles and achieving the desired effects with water jets posed major problems. Since solving them required an understanding of hydrostatics and the principles of natural motion, the work was well-suited to the expert members of the Académie des Sciences.

John Theophilus Desaguliers (1683-1744) was a French-born English Huguenot who made his name as a public lecturer in London and a demonstrator at the Royal Society, writing a very popular introduction to Isaac Newton's natural philosophy, the two-volume (1734-1744). This paper looks at the influence of three French natural philosophers, Edme Mariotte (1620-1684), Antoine Parent (1666-1716) and Bernard Forest de Bélidor (1698-1761), on the account of waterwheel functioning in the second volume of that work. The aim of the paper is to show that, although Desaguliers demonstrated a commitment to Newton's work, his own natural philosophical objectives also led him to borrow ideas from natural philosophers outside Newton's direct sphere of influence.

The larger structures are, the lower their mechanical strength. Already discussed by Leonardo da Vinci and Edmé Mariotte several centuries ago, size effects on strength remain of crucial importance in modern engineering for the elaboration of safety regulations in structural design or the extrapolation of laboratory results to geophysical field scales. Under tensile loading, statistical size effects are traditionally modeled with a weakest-link approach.

Edme Mariotte in the seventeenth century attributed halos to tiny ice prisms in the atmosphere. Christiaan Huygens attributed them to tiny spheres or cylinders. The two seemingly incompatible theories largely agree in their predictions for the common halos.
