Science Quote by Martin Fleischmann

There is a quiet defensiveness baked into Fleischmann's phrasing: the "problem" is not that Quantum Field Theory (QFT) is wrong, but that the move people keep insisting on - swapping out old quantum mechanics for the more modern, more complete framework - is "very demanding". That adjective does a lot of work. It signals technical difficulty, yes, but also social pressure: an implicit rebuttal to colleagues who treat QFT as the only serious language left in the room.

The line reads like a scientist drawing a boundary around acceptable critique. In late-20th-century physics-adjacent debates, "use QFT" can function less as a methodological suggestion than as a rhetorical gatekeeping tool: if you can't cast your phenomenon in renormalized fields and second quantization, you don't get to play. Fleischmann, best known for the cold fusion controversy, would have been unusually sensitive to that dynamic. When a claim is contested, demands for higher-theory formalism can operate as a demand for institutional legitimacy.

There's also a subtler admission: quantum mechanics remains the workhorse because it is usable. QFT is the prestige upgrade, but it comes with conceptual and mathematical overhead - infinities, regularization schemes, domain limits - that aren't just hard; they are easy to weaponize against messy, borderline phenomena. Fleischmann's intent, then, is not merely pedagogical. It's a plea for epistemic proportionality: match the theoretical machinery to the evidentiary situation, and don't pretend that invoking QFT automatically settles what reality is allowed to do.
