AIR - Am I Ready?

Before diving into a paper, a tool, or a concept, AIR helps you map where you are. Tick the concepts you know, flag the gaps, and get pointed to what you need. It's an honour system - the engine works better when you're honest with it.

Molecular Biology

GeneGuessr

by BrineDew

Identify proteins from structural and functional clues. Brutally hard.

Catalase provides: 17 supporting documents - fold terminology, crystallography milestones, Richardson's visual language, oligomer logic, and more. Plus AIR readiness check.

Iron Metabolism

by Catalase

From Lewis acids to ferroptosis. How iron moves through the body, and what goes wrong.

With 3D model

Oxygen Transport

by Catalase

Cooperativity, Bohr effect, fetal hemoglobin, diving mammals. The full picture.

With 3D model

Machine Learning

24 papers

Journal Club

arXiv papers

24 papers from foundational to recent, ranging from Show Your Working to DeepSeek v2 .

Catalase provides: curated selection, "why this matters" context for each paper, and AIR prerequisite mapping - some need only curiosity, others need transformers and statistics.

Computing

Building - Summer 2026

Iconic Algorithms

by Catalase

These are the algorithms that changed what's readily computable - beautiful ideas that make calculations efficient.

Catalase provides: AIR prerequisite mapping. Animated interactive walkthroughs.

CORDIC

How calculators compute trig functions with only shifts and adds. Interactive using CodingQuests. Big rotations close the gap - small rotations hit the exact value.

FFT

The algorithm behind everything from MP3s to polynomial multiplication. Watch it split, recurse and combine.

Smith-Waterman

Dynamic programming for sequence alignment. Watch the matrix fill, then trace back the answer.

Quantum Computing

Quantum Country

by Andy Matuschak & Michael Nielsen

A spaced-repetition introduction to quantum computing.

Catalase provides: AIR prerequisite check for complex numbers and linear algebra - points you to 3Blue1Brown if you're not ready.

Small Online Tools

by Catalase

Small Tools

Polynomials, vectors, complex numbers, charting, tree structure. Understand what the tools are for, what quantities they work with, before you use them.

Synthesis

Anomalous Ideas
