Natural vs Legal Rights
Politics
One tradition holds that some rights exist before government and limit what law may do; another holds rights are whatever the law grants.
Source: A distinction from rights theory
Decides whether a right survives a law that revokes it, or whether law simply defines what counts as a right.
Kolmogorov's Axioms
Mathematics
Probability is defined as a measure: nonnegative, additive over disjoint events, totaling one over all outcomes; randomness itself is never defined.
Source: After Andrey Kolmogorov
This turned probability into ordinary measure theory, sidestepping what randomness is while still computing with it correctly.
Block Universe
Physics
In relativity, past, present, and future are equally real parts of one four-dimensional spacetime; there is no universal 'now'.
Source: After the block-universe view of Minkowski spacetime
Observers in relative motion can disagree on which distant events are simultaneous, with no single observer privileged.
Split-Brain Interpreter
Psychology
After the corpus callosum is cut, the left hemisphere invents a plausible reason for an action the right hemisphere actually caused.
Source: After Michael Gazzaniga
Gazzaniga called this the interpreter; it suggests the brain narrates a coherent self even when it does not know its own reasons.
The Teleporter Problem
Philosophy
A machine destroys your body, then builds an exact copy elsewhere with all your memories. Did you survive, or did you just die?
Source: After Parfit, Reasons and Persons
Parfit used cases like this to argue that personal identity matters less than we assume it does.
Homeostatic Feedback
Biology
Many physiological systems hold an internal variable steady against outside change using feedback loops, not by keeping conditions fixed outright.
Source: After Claude Bernard and Walter Cannon
Blood sugar, body temperature, and pH all work this way: sensed, compared to a target, corrected, over and over.
