The Program That Talks About Itself: From PRA to ZFC to the Incompleteness Theorems
English | October 12, 2026 | ASIN: B0H2BRJ68J | 248 Pages | Epub | 1.02 MB
A quine is a program that prints its own source code. The trick that makes it work is the same one at the heart of Gödel's incompleteness theorems."There are mathematical truths that cannot be proved." "Mathematics cannot prove its own consistency." The incompleteness theorems are usually quoted in forms that drop the conditions that matter. This book skips the slogans and has you build the theorems yourself, with tools programmers use every day.What you will learnThe three layers of logic, theory (axioms), and metatheory, and why ZFC is a theory and not a logicWhy a language with only for loops (the primitive recursive functions), and PRA, the proof system built on it, are weak yet trustworthyHow formulas and proofs become integers (Gödel numbers), and how a proof checker can be written as a program that always haltsWhy Cantor's diagonal, the halting problem, and quines are one and the same techniqueHow the diagonal lemma, which matches a quine part for part, leads to the first and second incompleteness theoremsWhy "ZF cannot prove the axiom of choice" can only be proved with the condition "if ZF is consistent"A consistent theory that claims to be inconsistent, nonstandard natural numbers, and Gentzen's ε₀All the code in the book (Python and jаvascript, plus quines in Go and C in an appendix) has been run and its output checked. When the book states a theorem, it keeps hypotheses such as "if T is consistent."It is written for programmers without a background in mathematical logic who want to understand the incompleteness theorems precisely.

The Prime Ruler: A Creative Journey Through Number Theory, from Gaussian Integers to the p-adic World (The Art Of Creative Math Book 4)
English | September 7, 2026 | ASIN: B0H5CGXJ8Y | 726 pages | Epub | 13.67 MB
A prime is not a test. It is a ruler.Ask whether a prime divides a number and you get a yes or a no. Ask how many times, and then how many times it divides the number's neighbours, and a whole landscape appears that the yes-or-no question could never show.The Prime Ruler follows that single idea through twenty-three chapters, from the clock arithmetic of remainders to the left-infinite numbers of the p-adic world. Along the way, 2 stops being prime in the garden of Gaussian integers, Pascal's triangle turns into a fractal, −1 becomes a sum of powers of 2, the square root of 2 exists as long as the prime is 7, every triangle is isosceles, and a machine of Newton's grows roots one forced digit at a time. Then the geometry pays for itself three times over: in the hidden period of the Fibonacci numbers, in the Bernoulli fractions that judged Fermat's Last Theorem in 1847, and in the zeros of a recurrence, counted by a p-adic power series.Five movements, one ideaThe Clock - remainders, the Chinese Remainder Theorem, Fermat and Euler, primitive roots, and the art of forcing an equation to have integer answersNew Numbers - complex numbers, roots of unity, and the Gaussian integers, where 2 is no longer prime and the two-squares theorem answers itselfThe Ruler - digits and bases, the valuation v_p(n), Legendre's formula, lifting the exponent, polynomials as integers, and linear recurrencesThe p-adic World - Lucas and Kummer, left-infinite numbers, the ultrametric, automorphic numbers, Hensel's lemma, squares in the p-adic numbers, the Fibonacci entry point, Bernoulli numbers and regular primes, integer-valued polynomials, and the Skolem-Mahler-Lech theoremThe Open Frontier - five unsolved problems, each stated in one line, each waiting for a laptop and an ideaHow the book teachesEvery chapter opens with a question to wonder about, follows Curious Carl into the tempting wrong answer and out again, states its central move with a full why, and flags the trapdoor almost everyone falls through. A practice ladder climbs from warm-up to proof, with brief nudges and then every solution told in full, in prose. The p-adic chapters carry code corners: short programs that generated the examples, checked the theorems, and pushed a little past them. Five historical interludes, from Gauss to the Paris Academy of 1847, show where the ideas came from.Who it is forAmbitious high-school students preparing for AMC, AIME and olympiad-level number theory; MATHCOUNTS and olympiad coaches looking for a story rather than a syllabus; undergraduates meeting the p-adic numbers for the first time; and anyone who suspects the integers have more to say. No background beyond algebra is assumed; every advanced term is explained where it first appears.Part of the Creative Math Series from Ascent Math Press.

The Prime Ministers: Canada's Leaders and the Nation They Shaped
English | September 30, 2025 | ISBN: 1998365778 | 300 pages | EPUB (True) | 3.32 MB
After a surprising conversation with young Canadians who didn't recognize the name Lester B. Pearson - Nobel Peace Prize winner and Canada's fourteenth prime minister, author J.D.M. Stewart set out to bring the country's history to a new generation. The result is Canada's Prime Ministers, a lively, accessible chronicle of Canada's leaders, from Sir John A. Macdonald in 1867 to Mark Carney in 2025.With engaging prose and fresh insights, Stewart captures the defining moments of each prime minister's time in office, revealing how they managed relationships with Indigenous peoples, the environment, American presidents, and international powers. He also explores how their reputations have evolved - who has been forgotten, who remains controversial, and who has become a lasting part of Canada's cultural fabric. Canada's Prime Ministers is a necessary and important book, intended both for newcomers to Canadian history and those who have loved it for a long time.
