	Ladder paradox - Wikipedia, the free encyclopedia
		The ladder paradox or (barn-pole paradox) is a thought experiment in special relativity.
		The ladder frame is for a person sitting on the front of the ladder, with x′ and t′ being the ladder space and time axes respectively.
		What the ladder experiences is one end decelerating in order to catch up to the garage, then the next point of the ladder decelerating, followed by the next point, and so on until finally the entire ladder decelerates.

	Physical paradox - Wikipedia, the free encyclopedia
		Babinet's paradox is that contrary to naive expectations, the amount of radiation removed from a beam in the diffraction limit is proportional to twice the cross-sectional area.
		This paradox was sometimes used to argue that a homogeneous and isotropic universe as required by the cosmological principle was necessarily finite in extent, but it turns out that there are ways to relax the assumptions in other ways that admit alternative resolutions.
		Supplee's paradox: the buoyancy of a relativistic object (such as a bullet) appears to change when the reference frame is changed from one in which the bullet is at rest to one in which the fluid is at rest.

	The pole and barn paradox (ladder and garage paradox). From Einstein Light: module 4
		The pole and barn paradox (ladder and garage paradox).
		The pole and barn paradox (or the ladder and garage paradox) pose the question: Is the symmetry of length contraction paradoxical?
		This paradox is set up by the incautious use of the word 'when', which is italicised above for that reason.

	The Falling Ladder Paradox (Site not responding. Last check: 2007-10-14)
		An assumption in the familiar related rates problem of the falling ladder is that the top of the ladder stays in contact with the wall the entire time the ladder is falling.
		However, when the base of the ladder is sliding away from the wall at a constant rate, the top of the ladder eventually loses contact with the wall.
		The authors use differential equations to model the situation when the top of the ladder starts out in contact with the wall but eventually loses contact with the wall.

		If the bottom of the ladder is pulled along the level pavement directly away from the wall at 2 feet per second, how fast is the top of the ladder moving down the wall when the foot of the ladder is 4 feet from the wall?
		For the falling ladder problem given above, find the height above the ground at which the top of the ladder is moving at the speed of light (3 x 10

		The Falling Ladder Paradox -- from Mathematica Information Center
		Anyone who has studied calculus has probably solved the classic falling ladder problem of related rates fame....
		The paradox in this solution is that as the ladder nears the ground, [dy/dt] attains astronomical proportions.
