He possibly met Christiaan Huygens during this time (and/or on several other occasions) and may have learned about the magic lantern from him. Correspondence between them is known from 1667. At least from 1664 until 1670, Walgensten demonstrated the magic lantern in Paris (1664), Lyon (1665), Rome (1665–1666), and Copenhagen (1670). [15]

Christiaan Huygens was the first person to describe Saturn's rings as a disk surrounding Saturn. In 1655, Huygens became the first person to suggest that Saturn was surrounded by a ring, after Galileo's much less advanced telescope had failed to show rings. Galileo had reported the anomaly as possibly 3 planets instead of one.

For Huygens and Newton centrifugal force was the result of a curvilinear motion of a body; hence it was located in nature, in the object of investigation. According to a more recent formulation of classical mechanics, centrifugal force depends on the choice of how phenomena can be conveniently represented.
