Ravenparadox/Poundstone: "This herring is red" supports both contra positions: a) "All non-black things are non-ravens" and "all non-white things are non-ravens" (contra position of "All ravens are white") - it follows:. black is white - that is the paradox.

Knowledge paradox/prisoners paradox/Poundstone: (unexpected execution) only works if the other thinks about the situation and draws wrong conclusions.

Knowledge paradox/prisoners paradox/Quine/Poundstone: (unexpected execution) the "knowledge" here is an illusion. - The first conclusion, after which the prisoners cannot be executed on the last day is not valid.
The illogical is better off: he can suspect the right. - The assumption of a specific day causes that the execution can take place on any day.
Poundstone: error: the assumption when the impossible is excluded, there should remain something possible. - If the prisoner assumes the impossibility, he can be executed on any day.

Thomson's lamp/Poundstone: the light turns on for 1/2 minutes, then off for 1/4 minutes, then on for 1/8 ... Total: 1.
Question: is it on or off after 1 min? (Sum of infinite elements).
This is the wrong question. Analog: if the greatest number is odd/even.

Zenon/Achilles/Poundstone: Solution: overtaking after 111,111 ... cm - the "infinity" lies in Zenon's analysis, not in physics.
Arrow paradox: even in the relativity theory the moment remains blurry. - Also here we believe in cause and effect: the present determines the future.

How does the arrow know, where it must go? - This is no physical problem, the row term is no solution.

Olbers Paradox: four times the area balances four times weaker radiation - it would heat up on earth to the average temperature of stars - solution: redshift.

Tristram Shandy paradox/Russell/Poundstone: if he lived infinitly long, there would remain no day undescribed because there could be no day mentioned, for which it would be impossible. - A one-to-one allocation is possible but never completed.
But not at reversal infinite past: you cannot make an unambiguous assignment of certain days to certain years. - In the last year he cannot have written about one day of this year, - There will be an infinitly long incomplete manuscript.

Paradox/antinomy/Poundstone: general form: the illusion that all truth is also recognizable.
Unexpected execution: the victim is wrong because he thinks he can achieve something through logical reasoning, which is impossible to achieve in that way.
