| Infinity, infinite, philosophy: the result of a procedure that never ends, e.g. counting or dividing, or e.g. the continued description of a circular motion. In lifeworld contexts, infinitely continued processes such as infinite repetition or never-ending waiting are at least not logically contradictory. A formation rule does not have to exist for an infinite continuation to occur, as is the case, for example, with the development of the decimal places of real numbers. See also limits, infinity axiom, repetition, finitism, numbers, complex/complexity._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

W. Poundstone on Infinity - Dictionary of Arguments
I 221 Thomson's lamp/Poundstone: light turns on for 1/2 minutes, then off for 1/4 minutes, then 1/8 on ... Total: 1. Question: is it on or off after 1 min? (Sum of infinite elements). TZhis is the wrong question. Analog: the question if the greatest number is odd/even. I 228 ultimately physical limits: frequency, energy, switches. Cf. >Zeno, >About Zeno. I 224 Zenon/Achilles/Poundstone: Solution: overtaking after 111,111 ... cm - the "infinity" lies in Zeno's analysis, not in physics. Arrow paradox: even in the relativity theory the moment remains vague. - Here we also believe in cause and effect: the present determines the future. >Cause, >Effect, >Causation, >Causality, cf. >Determinism. How does the arrow know, where it must go? This is no physical problem, row term no solution. I 235 Infinity/border/Lukrez: wanted to prove infinity of the space: if someone hurls an arrow towards the border, it will either fly over the border, or something stops it. - So there is no border. PoundstoneVsLukrez: error, to accept a "something". I 236 Olbers Paradox: four times the area balances like four times weaker radiation - it would heat up on earth to the average temperature of stars. Solution: shift of red. >Olbers Paradox. I 237 Multiplicity/ZenonVs: even the shortest line contains an infinite number of points, then the whole universe in a nutshell. - In a hierarchy of even smaller particles containing mostly nothing, so there was nothing in 99.99% ... Solution/Poundstone: Blur effect by electrons. - We needed X-ray vision, which would be switched on only when straightforward connection. - Then myriads of electrons and quarks. - Because you cannot see an infinitly small point, everything would be invisible._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
