Newton was elected a Fellow of Trinity College, solidifying his position within the academic community.

At the relatively young age of 26, Newton was appointed the Lucasian Professor of Mathematics at Cambridge University, succeeding Isaac Barrow. This prestigious position came with considerable responsibilities, including lecturing and conducting research.

Newton was elected a Fellow of the Royal Society, the leading scientific society in England. This marked his formal entry into the broader scientific community and provided a platform for disseminating his research.

Newton briefly served as a Member of Parliament for Cambridge University. His involvement in politics was limited, and he reportedly spoke only once during his term, asking for a window to be closed.

Newton left Cambridge University to take a position as Warden of the Royal Mint in London. This marked a significant shift in his career, from academia to government service.
