Mechanistic interpretability reverse-engineers neural networks into features and circuits. What it has found in GPT-2 and Claude, and what it cannot yet do.

Schrödinger's cat was designed in 1935 to mock quantum mechanics, not celebrate it. Here's what Schrödinger actually argued and what modern physics says now.

Quantum mechanics rests on five foundational principles that explain all atomic and subatomic behavior. This primer covers each principle, its experimental basis, and what it means.

Quantum computers use qubits, superposition, and entanglement to solve problems classical machines cannot. Learn how they work, what algorithms run on them, and where the field stands in 2026.
