Four Venn diagrams for the core logical operations: A ∧ B (AND), A ∨ B (OR), A ⊕ B (XOR) and A → B (IF ... THEN), with the shaded regions that make boolean logic instantly clear. For math and computer science teachers, programmers, electrical engineers, logic students and data analysts. A smart gift for teachers, coders and STEM graduates.
Description: A mind map centered around the word "Maths". Branching out are circles containing icons and text representing different mathematical fields: Trigonometry, Probability, Data, Geometry (two instances), Number Theory (two instances), Logic, Set Theory (two instances), Statistics, and Calculus. Each section has distinct icons and text labels.
Description: "The paradox that shook the foundations of mathematics. A gold set half in and half out of itself, among ordinary sets, captures the moment naive set theory broke and modern logic was born. Russell's paradox (1901): the set R of all sets that do not contain themselves. Does R contain R? Shown as a set straddling its own boundary, with R = {x | x ∉ x} and R ∈ R ⟺ R ∉ R. For mathematicians, set theory and logic students, computer scientists, philosophy teachers and fans of the barber paradox. A brainy gift for anyone who loves foundations of math.
