Courses
Every course here covers the same ground as its university equivalent, broken into numbered micro-videos — most of them twenty seconds long. Every video is one idea. Every idea has a number, and every number knows what comes before it, so you can start anywhere and always find your way back to solid ground.
Why it’s built this way
Six years in the classroom taught me one thing above everything else: students fall behind one missed prerequisite at a time, until nothing downstream makes sense and there’s no visible way back. A lecture course can’t fix that, because the dependencies are invisible. These courses are built so they can’t be — every idea is one numbered video, and every number knows exactly which numbers come before it.
These aren’t highlight reels. Each course is the whole map: every claim checked against scholarly references and standard texts, with the full source list published for anyone to inspect. The courses are free and stay free.
Now teaching
The entire introductory logic canon. Twenty seconds at a time. The full two-semester introductory canon — arguments and validity, categorical and propositional logic, natural deduction, predicate logic, induction and probability, and fallacies — one numbered idea at a time.
Enter the course 691 lessons · 653 atoms · 16 procedures · 22 capstones · 691 of 691 liveThe entire introductory psychology canon. Twenty seconds at a time. The full introductory canon — research methods, biopsychology, sensation and perception, learning, memory, cognition, lifespan development, personality, social psychology, and the disorders and their treatment — one numbered idea at a time.
Enter the course 598 lessons · 547 atoms · 27 procedures · 24 capstones · 589 of 598 liveThe entire language of medicine. Twenty seconds at a time. Not a vocabulary list to memorize but a system to decode — word parts and the rules that combine them, then one body system at a time, so a term you have never seen becomes readable on sight.
Enter the course 210 lessons · 189 atoms · 9 procedures · 12 capstones · 0 of 210 liveThe entire introductory philosophy canon. Twenty seconds at a time. The full introductory canon — how arguments work, epistemology, philosophy of religion, free will, personal identity, philosophy of mind, ethics, and political philosophy — one numbered idea at a time.
Enter the course 210 lessons · 186 atoms · 11 procedures · 13 capstones · 0 of 210 liveThe entire introductory ethics canon, first video to last. The full introductory canon — moral reasoning, relativism and subjectivism, egoism and the social contract, utilitarianism, Kant, virtue ethics and the ethics of care, value theory, and the applied questions — one numbered idea at a time.
Enter the course 292 lessons · 249 atoms · 33 procedures · 10 capstones · 57 of 292 liveArtificial intelligence from zero. Twenty seconds at a time. Built in dependency order rather than headline order — agents and search, games, constraints, logic and notation, probability and belief, decisions, machine learning, language and vision, and the limits the field is still arguing about — one numbered idea at a time.
Enter the course 326 lessons · 298 atoms · 11 procedures · 17 capstones · 0 of 326 liveThe whole introductory computer science canon. Twenty seconds at a time. Built in dependency order rather than language-first — computational thinking, algorithms and data structures, machines and low-level programs, systems and operating systems, languages, data management, software engineering, the web and cloud, and security — one numbered idea at a time.
Enter the course 295 lessons across eleven units · 0 of 295 liveHow American government actually works. Twenty seconds at a time. Built in dependency order rather than headline order — the founding documents, federalism, civil liberties and civil rights, public opinion, elections, the three branches, the bureaucracy, and policy — one numbered idea at a time.
Enter the course 537 lessons across eleven units · 0 of 537 liveThe whole introductory sociology canon. Twenty seconds at a time. Built in dependency order rather than topic order — the theoretical perspectives, research methods, culture and socialization, groups and deviance, stratification and global inequality, race, gender and aging, the major institutions, and social change — one numbered idea at a time.
Enter the course 263 lessons across nine units · 0 of 263 liveThe whole college algebra canon. Twenty seconds at a time. Built so each rule follows from the one before it — real numbers and exponents, polynomials and factoring, equations and inequalities, functions and their graphs, exponentials and logarithms, and systems — one numbered idea at a time.
Enter the course 1,133 lessons across fourteen units · 0 of 1133 liveThe whole introductory biology canon. Twenty seconds at a time. The largest course here, built in dependency order — the chemistry of life, cells and membranes, metabolism, genetics and gene expression, evolution, microbial and plant and animal diversity, human physiology, and ecology — one numbered idea at a time.

Who makes this
I’m Justin Ryan Carver. I spent six years as an adjunct professor of philosophy at a community college, teaching Introduction to Logic, Introduction to Philosophy, and Introduction to Ethics and Values. I also hold an Education Specialist degree in Educational Leadership, a Master of Arts in Liberal Studies, and Project Management Professional certification.
The résumé isn’t the point, though — every claim in every course is mapped to published sources you can check yourself. Trust the receipts as much as the teacher.
