	Scientific Realism is the philosophical position that the world described by science is real, regardless of whether it can be directly observed. It is the belief that successful scientific theories are "True" (or at least "Approximately True") and that the "Unobservable" things they talk about—like atoms, black holes, and quarks—actually exist. It stands in opposition to '''Anti-Realism''' (or Instrumentalism), which argues that science is just a "Tool" for predicting observations and that we shouldn't care if the underlying "Gears" are real.

Scientific Realism is the philosophical position that the world described by science is real, regardless of whether it can be directly observed. It is the belief that successful scientific theories are "True" (or at least "Approximately True") and that the "Unobservable" things they talk about—like atoms, black holes, and quarks—actually exist. It stands in opposition to **Anti-Realism** (or Instrumentalism), which argues that science is just a "Tool" for predicting observations and that we shouldn't care if the underlying "Gears" are real.

== Remembering ==
* '''Scientific Realism''' — The view that our best scientific theories give us a true description of the world.
* '''Anti-Realism (Instrumentalism)''' — The view that theories are just useful tools for calculation, not true descriptions of reality.
* '''Unobservable''' — Entities that cannot be seen with the naked eye (e.g., electrons, gravitational waves).
* '''Theoretical Entity''' — A "thing" that is part of a theory but hasn't been directly proven to exist (e.g., String Theory strings).
* '''The No-Miracles Argument''' — The idea that it would be a "miracle" for science to work so well if it weren't actually true.
* '''Pessimistic Meta-Induction''' — The historical observation that almost all past scientific theories have been proven wrong, so current ones likely are too.
* '''Approximate Truth''' — The idea that theories get "closer" to the truth over time.
* '''Structural Realism''' — The middle-ground view that the *equations* (the structure) are real, even if the *objects* aren't.
* '''Empirical Adequacy''' — When a theory correctly predicts all the data we can observe.
* '''Success of Science''' — The ability of science to build rockets, cure diseases, and create computers.
* '''Underdetermination''' — The fact that multiple different theories can often explain the same set of data.
* '''Constructive Empiricism''' — Bas van Fraassen's view that science only aims for "empirical adequacy," not "truth."
