Plasma TVs get a bit dimmer and redder as they age, but they still maintain excellent picture quality during the first year. None of these findings spoils my positive impression of high-end Samsung and Panasonic plasmas. I haven't tested any LED/LCDs long-term, so I can't say one way or another how they age.
Definition of an argument [edit]. An argument (in the context of logic) is defined as a set of premises and a conclusion where the conclusion and premises are separated by some trigger word, phrase or mark known as a turnstile. For example: 1 I think; therefore I am. There is only one premise in this argument, I think.
Deductive and Inductive Arguments. A deductive argument is an argument that is intended by the arguer to be (deductively) valid, that is, to provide a guarantee of the truth of the conclusion provided that the argument's premises (assumptions) are true. deductive argument is valid or else invalid. The difference between the two kinds of arguments does not lie solely in the words used; it comes from the relationship the author or expositor of the argument takes there to be between the premises and the conclusion.
