11 Jan 1672: The Royal Society #London elects Isaac Newton a fellow #otd - mainly for his building of the reflection telescope (BM)

On January 2, 1729, German astronomer Johann Daniel Titius was born. He is best known for formulating the Titius–Bode law, a hypothesis that the bodies in some orbital systems, including the Sun’s, orbit at semi-major axes in a function of planetary sequence. The formula suggests that, extending outward, each planet would be approximately twice as far from the Sun as the one before.

In general Isaac Newton is presented as an asocial, grumpy old man, who loved nobody & was loved by nobody. However, in realty, Isaac had acquaintances with whom he was on good terms, genuine friends & also that he was a kind & loving family man.
