- But the Cartesian theory, like the later speculations of Kant and
**Laplace**, proposes to give a hypothetical explanation of the circumstances and motions which in the normal course of things led to the state of things required by the law of attraction. - In preparation for these he spent the winter of 1877-1878 in reading up original treatises like those of
**Laplace**and Lagrange on mathematics and mechanics, and in attending courses on practical physics under P. G. - The application of this to telegraphic purposes was suggested by
**Laplace**and taken up by Ampere, and afterwards by Triboaillet and by Schilling, whose work forms the foundation of much of modern telegraphy. - In his Naturgeschichte des Himmels, in which he anticipated the nebular theory afterwards more fully developed by
**Laplace**, Kant sought to explain the genesis of the cosmos as a product of physical forces and laws. **Laplace**supposed the existence of a primeval nebula which extended so far out as to fill all the space at present occupied by the planets.
