Notes on Conversation of Linus Pauling with Albert Einstein on 16 November 1954 (scarc.library.oregonstate.edu) On 16 November 1954 I talked with Albert Einstein at his home in Princeton, for a couple of hours, about various matters, scientific in part, but especially about the world as a whole.

Eta Aquilae (Wikipedia) Eta Aquilae (η Aql, η Aquilae) is a multiple star in the equatorial constellation of Aquila, the eagle. It was once part of the former constellation Antinous. Its apparent visual magnitude varies between 3.49 and 4.3, making it one of the brighter members of Aquila. Based upon parallax measurements made by the Gaia spacecraft on its third data release (DR3), this star is located at a distance of roughly 272 parsecs (890 light-years). The primary component is a Classical Cepheid variable.
