I study how matter becomes machinery: how a slight asymmetry persists, propagates, and shapes what follows.

The first problem is to decide what the physical object is. The genetic code is not just a table; error costs give it a geometry. A molecular recognizer is not a rigid lock; deformation can make a slight mismatch more specific than perfect fit. A protein is not a moving shape; function is carried by strain through an amorphous structure. And in water, the molecule may not be the whole object: its surface imposes boundary conditions on the surrounding liquid.

The cell makes the difficulty recursive. A DNA sequence becomes operative only through machinery that reads it; that machinery must itself be rebuilt. Reproduction is therefore reconstruction of the interpreter, boundary, and metabolism—not copying alone. This is the physical problem behind What Is Life?

Elsewhere I ask how much quantum structure requires quantum mechanics . Classical hydrodynamic matter can carry quasiparticles, flat bands, and exceptional topology; ordinary rotations lead directly to SO(3) and SU(2).
