A problem family — different problems, same issues

30 problems across 15 fields

These 30 problems come from quantum computing, particle physics, cultivated meat, gene therapy, and advanced materials. In each, what works at lab scale can't be manufactured. Biological products make up a growing share: cultivated meat, precision fermentation, gene therapy vectors, and bioprinted organs all involve living systems that change when scaled. A graduate student's hands can be more precise than any machine. Engineered organisms evolve away from the traits they were built for. Iron reduced with hydrogen forms unexpected carbide phases at furnace scale.

It works at lab scale. At factory scale living systems adapt, materials behave differently, and precision achieved by hand can't be mechanized.

Ways this family shows up

Conventional scale-up. Yield loss, unstable processes, and capital needs at industrial scale
Precision by hand. Reaching in a factory the precision that lab methods achieve by hand
Living systems. Organisms respond to changed conditions in ways that are hard to predict
Process chemistry. Reactions behave differently at production scale: unexpected phases, corrosion, heat to manage
Proving it qualifies. The process works but can't demonstrate that it meets certification requirements
