@divbyzero @sk8asd123 I like the section on vortex theories in Helge Kragh's "Higher Speculations: Grand Theories and Failed Revolutions in Physics and Cosmology". https://t.co/Kh9VQD7ikD

@machina_animus The Wikipedia articles I linked to make a good start. Also try Cover and Thomas' "Elements of Information Theory", Li and Vitanyi's "An Introduction to Kolmogorov Complexity and Its Applications" and this paper: https://t.co/HVNZqGbahk

@JasonHise64 @BartoszMilewski @StartsWithABang Besides the open-access link I just gave, the best place to read about this - certainly more entertaining! - is Abraham Pais' biography of Einstein called "Subtle is the Lord". It goes through all his attempts at unified field theories. (2/2) https://t.co/RHcX4sKfbb

@GerardWesty31 @sfera314 Yes, but I'm more interested in how the "swerve" foreshadowed spontaneous symmetry breaking due to quantum mechanics. Most of this we get through Lucretius' poem "De Rerum Natura": https://t.co/e90M0gd9am https://t.co/ZuXf4LlDmO

@JadeMasterMath To the extent logic is about Boolean algebras, co-logic is about Stone spaces, since the category of Stone spaces is the opposite of the category of Boolean algebras. Check out Peter Johnstone's book "Stone spaces", or this: https://t.co/fMk4nXylQ7

@DiffGeometer1 @TheBlueWizard9 Here's my short introduction to spinors which explains the difference between Dirac spinors, Weyl spinors, Majorana spinors and Majorana-Weyl spinors: https://t.co/DYv1LBNsTq Trautman's book The Spinorial Chessboard is dense but packed with good info: https://t.co/mTlDR0MXTi
