Tyranny of the Majority
Politics
A majority's will can crush a minority as completely as any king's, since counting votes alone sets no limit on what the majority may do.
Source: After Alexis de Tocqueville
Raises whether democracy needs constraints beyond majority rule to protect those who keep losing votes.
Non-Euclidean Geometry
Mathematics
Drop Euclid's parallel postulate and keep the rest; consistent geometries follow where lines through a point never meet, or where all of them do.
Source: After Bolyai and Lobachevsky
Bolyai and Lobachevsky showed the postulate was never forced by the others, reopening what counts as geometric truth.
Noether's Symmetry Link
Physics
Every continuous symmetry of a physical system implies a conserved quantity: time symmetry gives energy, space symmetry gives momentum.
Source: After Emmy Noether, 1918
Conservation laws are not separate rules; they fall out of symmetry once you look at mechanics the right way.
Cognitive Dissonance
Psychology
Holding two conflicting beliefs, or a belief and an action, creates discomfort; people resolve it by changing the belief, not the behavior.
Source: After Leon Festinger, 1957
Explains why people who spend money or effort on something often talk themselves into liking it more, not less.
The Fear of Death
Philosophy
Death is nothing to us. While we exist, death is not here; once death comes, we no longer exist.
Source: After Epicurus, Letter to Menoeceus
Epicurus tried to argue fear of death out of existence with logic alone. Ask whether the argument actually calms anyone.
Endosymbiotic Theory
Biology
Mitochondria and chloroplasts began as free-living bacteria engulfed by an ancestral cell, not structures the host genome built from scratch.
Source: After Lynn Margulis
Explains why these organelles carry their own DNA and divide independently; long resisted before genetic evidence confirmed it.
