2023 was a light reading year for me, 21 books. Though part of this is that I got distracted learning algebraic geometry, and I never feel like I should count a math or physics textbook as read unless I’ve done a lot of the exercises and can say I’ve digested the content. Book of the year for me was “The Weil Conjectures: On Math and the Pursuit of the Unknown” by Karen Olsson. A non fiction muse on abstract math and brother (math) and sister (philosophy) André and Simone Weil.

@mcnees Another contribution is that Bohm, together with Pines, developed to the random phase approximation as it is used in condensed matter https://en.m.wikipedia.org/wiki/Random_phase_approximation

1. Random phase approximation
  
  The random phase approximation (RPA) is an approximation method in condensed matter physics and in nuclear physics. It was first introduced by David Bohm and David Pines as an important result in a series of seminal papers of 1952 and 1953. For decades physicists had been trying to incorporate the effect of microscopic quantum mechanical interactions between electrons in the theory of matter. Bohm and Pines' RPA accounts for the weak screened Coulomb interaction and is commonly used for describing the dynamic linear electronic response of electron systems. It was further developed to the relativistic form (RRPA) by solving the Dirac equation.In the RPA, electrons are assumed to respond only to the total electric potential V(r) which is the sum of the external perturbing potential Vext(r) and a screening potential Vsc(r). The external perturbing potential is assumed to oscillate at a single frequency ω, so that the model yields via a self-consistent field (SCF) method a dynamic dielectric function denoted by εRPA(k, ω). The contribution to the dielectric function...

In quantum computing when the probabilities don’t add up to 1 you think “oh no I forgot to normalize” In finance you think “money!”

You get a fist authorship, and you get a first authorship https://arxiv.org/abs/2304.01393

1. Every Author as First Author
  
  We propose a new standard for writing author names on papers and in bibliographies, which places every author as a first author -- superimposed. This approach enables authors to write papers as true equals, without any advantage given to whoever's name happens to come first alphabetically (for example). We develop the technology for implementing this standard in LaTeX, BibTeX, and HTML; show several examples; and discuss further advantages.
