 + Abstract
 + In his 1685 paper “Observationes cyclometricae” published in Acta Eruditorum, Adam
 + Adamandy Kochanski presented an approximate ruler-and-compass construction for rectifi- ´
 + cation of the circle. It is not generally known that the first part of this paper included an
 + interesting sequence of rational approximations of π. Kochanski gave only a partial explana- ´
 + tion of the algorithm used to produce these approximations, while promising to publish details
 + at a later time, which has never happened. We reconstruct the complete algorithm and discuss
 + some of its properties. We also argue that Kochanski was very close to discovery of continued ´
 + fractions and convergents of π.

 + Quantum Fields: The Real Building Blocks of the Universe - with David Tong  6,065,075 views  Feb 15, 2017
 + According to our best theories of physics, the fundamental building blocks of matter are not particles, but continuous fluid-like substances known as 'quantum fields'. David Tong explains what we know about these fields, and how they fit into our understanding of the Universe.

 + David Tong is a professor of theoretical physics at Cambridge University, specialising in quantum field theory.https://youtu.be/zNVQfWC_evg?si=N0-udysPRZ4ZS4jT
