1632 book by Galileo Galilei
heat capacity ratio
thermodynamic ratio of isobaric to isochoric specific heat capacities
temporal paradox
theoretical paradox resulting from time travel
Alice and Bob
characters used in cryptography and science literature
philosophy of space and time
branch of philosophy relating to spatiality and temporality
Mach's principle
principle that inertia is determined by the large-scale distribution of matter
relativity of simultaneity
concept that distant simultaneity is not absolute, but depends on the observer's reference frame
Carnot's theorem
in thermodynamics, the principle that any heat engine operating between the same two thermal reservoirs cannot have an efficiency greater than a reversible heat engine operating between the same reservoirs
ladder paradox
thought experiment in special relativity

theory stating that external physical reality is a mathematical structure
Brownian ratchet
thought experiment and instance of a perpetual motion machine of the second kind

thought experiment
Bell's spaceship paradox
thought experiment in special relativity: “a string hangs between two spaceships that start accelerating simultaneously equally in an inertial frame; will the string break?”

thought experiment in physics
van Stockum dust
exact solution of the Einstein field equation with dust rotating about an axis of cylindrical symmetry
reverse sprinkler
physics thought experiment popularized by Richard Feynman, consisting of a sprinkler-like device which is submerged in a tank and made to suck in the surrounding fluid
bucket argument
argument demonstrating that rotational motion cannot be defined as the relative rotation of the body with respect to the immediately surrounding bodies
Popper's experiment
experiment proposed by Karl Popper to put to the test different interpretations of quantum mechanics
flux linkage
interaction of a multi-turn inductor with the magnetic flux
