Jean Bouguer taught his son Pierre both mathematics and hydrography, and Pierre turned out to be an outstanding pupil. A real child prodigy, he had a deep understanding of mathematics and science by the age of fifteen years. Now a remarkable thing happened. Jean Boutroux died when Pierre was fifteen years old and so his professorship of hydrography became vacant. Pierre applied for his father's professorship and he was such a remarkable young man, both brilliant and knowledgeabl, that he was appointed. One might think that such early brilliance and achievement would lead to him leading an unexciting life. However, this is far from the truth for his achievements became still more impressive. In 1727 he won the Grand Prix of the for his submission on masts of ships. Two years later he again won the grand prize, this time with an essay on observing the altitudes of stars at sea then, in 1731, he won his third Grand Prix from the

Pierre Bouguer was a French scientist who was the first to attempt to measure the density of the Earth using the deflection of a plumb line due to the attraction of a mountain. He made measurements in Peru in 1740. A more successful use of this method by the astronomer Maskelyne placed the density between 4.5 and 5.

"Bouguer is regarded as the founder of photometry, the branch of optics concerned with measuring the intensity of light. His two most important contributions to the subject are contained in his Essai, the first part of which states his method of comparing the relative brightness of two lights by using the eye as a null indicator (i.e., to establish the equality of brightness of two adjacent surfaces) and applying the laws of inverse squares. The second part contains the first statement of what is often called Bouguer's law: that in a medium of uniform transparency, the light remaining in a collimated beam is an exponential function of the length of its path in the medium. This law was restated thirty-one years later in Lambert's Photometria and is thus sometimes referred to as Lambert's law. (DSB, Norman, 283).

Pierre Bouguer Born: 16 Feb 1698 in Le Croisic, France Died: 15 Aug 1758 in Paris, France Pierre Bouguer succeeded his father Jean Bouguer at the age of 15 as royal professor of hydrography. He was a scientist who was the first to attempt to measure the density of the Earth using the deflection of a plumb line due to the attraction of a mountain. Bouguer, together with La Condamine , made measurements in Peru in 1740 publishing his results in La Figure de la terre (1749). A more successful use of this method by the astronomer Maskeleyne placed the density between 4.5 and 5. In mathematics Bouguer studied pursuit curves in 1732. He also wrote on naval maneuvers and navigation and, in ship design, derived a formula for calculating the metacentric radius (a measure of ship stability).

38. Bouguer, Traité Du Navire pierre bouguer s work was the first significant treaty on shipbuilding in France for At the age of fifteen pierre bouguer succeeded his father, Jean, http://nautarch.tamu.edu/shiplab/01paul/manuscripts/Bouguer.htm

Monseur Pierre Bouguer Title: "Treaty of the Ship, its Construction, and its Movements By M[monseur]. Bouguer, of the Royal Academy of Sciences (Paris)." Originally published by Jombert, 1746. Paris. Pierre Bouguer's work was the first significant treaty on shipbuilding in France for nearly half a century. In that time the practice of shipbuilding had made significant progress. Bouguer was perhaps the first scientist to make use of mathematics in construction and operations of a vessel. Also, this work was the first that taught calculating of the center of gravity of a hull (metacenter). The use of displacements and centers of gravity allowed shipwrights to create more stable ships. Although, it is unlikely that this work had much influence on the shipwrights of the time, Bouguer lays the foundation that allowed Duhamel du Monceau to later advance this work. The work is divided into three books: • Two- The ship in water, in port, and "out of calm water." Methods to measure the hull, determine the metacentre, the centre of gravity and the effects of rolling.

39. Duhamel Du Monceau, The Elements Of Naval Architecture... M. pierre bouguer - Traité du navire, de sa construction, bouguer, M. pierre.A Treatise on Ships, and their Construction, and their Movements. Paris. http://nautarch.tamu.edu/shiplab/01paul/manuscripts/Duhamel.htm

Henri-Louis Duhamel du Monceau The Elements of Naval Architecture ... (1752 and 1758) Henri Louis Duhamel du Monceau published The Elements of Naval Architecture, a Practical Treatise on the Construction of Ships Paris. C.A. Jombert, 1752. Like his predecessor, Bouguer, Duhamel du Monceau was a member of the Royal Academy of Sciences as well as various other organizations (listed on the cover page seen below). It should not come as a surprise then that both his and Bouguer's works were published by the same publisher and concern the identical topics. The 1754 English treatise by Mungo Murray is a compilation, translation and modification of much Duhamel du Monceau and Bouguer's treatises. Duhamel du Monceau beings the treatise by acknowledging the work of Bouguer and Euler. Directly after he makes note that he wishes his work to be translated into English. Also, Duhamel du Monceau is clear that the purpose of his work is for the instruction of young or new shipwrights. The book continues the trend of shipbuilding on a mathematical basis and is divided into three parts: -Finding or creating the proper external shape of the ship that allows for good service.
