Eat Better Without Dieting

A working mental model of the cosmos — how we actually know what we know (light, telescopes, spectra), what the solar system, stars, and galaxies are, how the universe began, and how the search for other worlds and life is going. The trunk gives you the full map; clusters dive into the naked-eye sky, observatories, the sun, the planets, black holes, cosmology, and alien worlds.

A working understanding of probability and statistics — how to reason under uncertainty, turn data into claims, and recognize when those claims are honest. The trunk gives you the core vocabulary and the inference pipeline; clusters dive into Bayesian reasoning, frequentist theory, regression, stochastic processes, and experimental design.

A working understanding of mathematics — the universal language scientists, engineers, and quants use to describe the world. The trunk gives you the throughline from how mathematicians think to how math models reality; clusters dive into proof, trig, calculus mechanics, advanced linear algebra, number theory and cryptography, probability, stochastic processes, and the foundational limits of math itself.

A career-spanning roadmap from absolute beginner to job-ready mid-level software engineer. The trunk gives you the complete throughline — the concepts, languages, systems, and professional skills every engineer needs — and clusters let you go deep on specific topics (Python, React, Kubernetes, system design, security, career strategy) when they matter.

A working understanding of psychology — what the science actually claims about how minds, brains, and behavior fit together. The trunk gives you the orientation a literate professional needs (how psychology knows what it knows, the brain behind behavior, learning, memory, decision-making, emotion, personality, social influence, development, pathology, and what therapy does); clusters dive into research methods, perception, cognition mechanics, social influence tactics, the field guide of disorders, applied behavioral science, and the psychology of everyday life.

A working understanding of how to start, validate, launch, and scale a real business. The trunk walks the founder arc from mindset and customer discovery through business models, MVPs, positioning, operations, sales, fundraising, and leadership. Clusters dive deep into the tactical playbooks behind each act — interview techniques, MVP fidelity, pricing, channels, term sheets, hiring, unit economics.
