Magnetischer Verein and its journal were conceived, and the atlas of geomagnetism was published.
From 1850 onwards Gauss’s work was that of nearly all practical nature. He disputed over a modified Foucalt pendulum in 1854, and was also able to attend the opening of the new railway link between Hanover and Gottingen, but this outing proved to be his last. The health of Carl Gauss deteriorated slowly and he died in his sleep early in the morning of February 23, 1855.
Carl Gauss’s influence in the worlds of science and mathematics has been immeasurable. His abstract findings have changed the way in which we study our world. In Gauss’s lifetime he did work on a number of concepts for which he never published, because he felt them to be incomplete. Every one of these ideas (including complex variable, non-Euclidean geometry, and the mathematical foundations of physics) was later discovered by other mathematicians. Although he was not awarded the credit for these particular discoveries, he found his reward with the pursuit of such research, and finding the truth for its own sake. He is a great man and his achievements will not be forgotten.
