Russel, makes reference to wittgensteins constructs vaguely. I recommend checking out logicus tracatus philosophicus as it is an interesting contribution to the formation of logic as a teue discipline of mathematics and when the world finally had a cohesives train of thought that cemented mathematics as another ideology created by humans. Not this mystical construct with non-contradictory extensions of original axioms of ideology.

Bought this book after seeing it referenced in Jackson's "Classical Electrodynamics" and so far it is wonderful. I have only grazed the surface, but just from the concise and explicit definitions given it seems wondeful. However, there is only slight intersections with Electrodynamics since the topic covers optics rather than the general topic of electromagnetic phenomena.

The book is called "Principles of Optics" by Born and Wolf.

Im not going to do them cause I've already done them. But here ya go! Taken from "Introduction to Real Analysis," by William Trench

I enjoyed them. The first book is good on its own, supplemental resources arent really needed and the main citations are from direct translations. The second book is really big and long amd goes in depth on newton's "principia naturalis..." Researching the cited sources in conjuction to the text is actually extremely useful. Especially, for those not acquainted with the old school of thought in mathematics and the pedagogical rigor that it contains.

I like this guys channel. He does nice softcore examples of proofing techniqies generally required and even does and a set theory basis for the natural numbers rather than the usual peano's axioms.

I just found out recently that converting between number systems (i.e. decimal to binary) uses successive multiplications or divisions depending on the digit placement. Then it dawned upon me, so is this why logarithms and modulizing number systems are interesting in Number theory. I always wondered why they make computer engineers study number theory.

Its a pretty interesting topic to dive into.

I dont have any links really have links on this one. Mayber check out the history of logarithms and see the correlation.

I would look at the translated version of "Mirifici Logarithmorum Canonis Descriptio," and look at what mods do.

For instance, using the integer number system and modulizing it by 2, I build the set of number which could be represented as binary numbers.
