- Macroscopic indeterminism(as the consequence that Batterman says is not justified)
- The idea that large, everyday objects (the kind we can see) behave in ways that are fundamentally unpredictable and not determined by prior causes.
- Physically unwarranted(describing whether the inference from quantum to everyday unpredictability is valid)
- Not supported by actual scientific evidence or physical reality; something that seems logical but doesn't actually hold up when you test it in nature.
- Quantum mechanics(the scientific framework being discussed)
- The science of how the tiniest things in the universe (atoms, electrons, photons) behave—which turns out to work very differently than everyday objects.
- Quantum uncertainty(as what some people assume causes unpredictability in everyday life)
- The fundamental fact that at the quantum level, you cannot know both a particle's exact position and exact speed at the same time—there's always some unavoidable fuzziness.
- Robert Batterman(as the main figure arguing the point in this statement)
- A contemporary philosopher of physics who studies how different scientific theories relate to each other, particularly how the laws of everyday objects emerge from quantum mechanics.
- classical limit(De Broglie–Bohm theory; discussed as a puzzle by Holland (1996))
- The regime in which quantum mechanical descriptions reduce to or reproduce classical Newtonian behavior.
- ℏ (h-bar)(as the symbol representing Planck's constant)
- A fundamental constant in quantum mechanics (a fixed number used in equations) that represents how 'quantum' something is; smaller values mean less quantum weirdness.
- ℏ→0(describing the traditional method to connect quantum and classical physics)
- Mathematical shorthand meaning 'letting the quantum constant get smaller and smaller, approaching zero'; a standard way physicists try to recover everyday physics from quantum equations.
