The ladder paradox (or barn-pole paradox) is a thought experiment in special relativity. It involves a ladder, parallel to the ground, travelling horizontally at relativistic speed (near the speed of light) and therefore undergoing a Lorentz length contraction .
Ladder paradox: Introductory relativity problem about a ladder, a barn, and simultaneity. Mocanu's velocity composition paradox: Which formula should be used to ...
In philosophy, Wittgenstein's ladder is a metaphor set out by Ludwig Wittgenstein about learning. In what may be a deliberate reference to Søren Kierkegaard 's Concluding Unscientific Postscript to Philosophical Fragments , [ 1 ] [ 2 ] the penultimate proposition of the Tractatus Logico-Philosophicus (translated from the original German) reads:
In 1961 Rindler used the Fitzgerald contraction as the premise of his article "Length contraction paradox". [3] The thought experiment is now called the ladder paradox . In September 1963 he took up a position at the newly founded Southwest Center for Advanced Studies , the private research organization that in 1969 became the University of ...

In physics, precisely in the study of the theory of general relativity and many alternatives to it, the post-Newtonian formalism is a calculational tool that expresses Einstein's (nonlinear) equations of gravity in terms of the lowest-order deviations from Newton's law of universal gravitation.
The data reveals an interesting paradox about the state of leadership today: While disruptions have increased, so has confidence in leadership’s ability to weather the storm.
The Alcubierre metric defines the warp-drive spacetime.It is a Lorentzian manifold that, if interpreted in the context of general relativity, allows a warp bubble to appear in previously flat spacetime and move away at effectively faster-than-light speed.
