RARE FIRST EDITION of Malus' prize-winning work on double refraction. Malus took part in the Egyptian expedition as an engineering officer. Director of Studies at the Ecole Polytechnique in 1811, he died the following year at the age of thirty-seven. Malus took up the work of Huygens, Newton and Wollaston. He deduced Huygens's law by means of the principle of the least action. Also of great importance is his law for the relative intensities of the ordinary and extraordinary rays. After a century of discussion, his research led to the law on the intensity of polarized light that bears his name. He studied the polarization of light by reflection and showed that his theory of double refraction was compatible with the principle of least action and the corpuscular hypothesis.
