The first paper: We describe principles of new cybernetics and use theseprinciples for resolution of basic physical paradoxes. It demonstratesuniversality of the principles of new cybernetics.  The second paper: recent letter by Maccone presents a solution based on theexisting laws of quantum mechanics to the arrow-of-time dilemma. He argues thatall phenomena in which the entropy decreases must not leave any information (inthe observer's memory) of their having occurred because the observer is a partof the whole system. Maccone concludes that quantum mechanics is necessary tohis argument, which he believes does not otherwise work in classical mechanics.This Comment consists of four parts. We discuss the basic problems in the firstpart. This Comment and the previously published Comment by Jennings and Rudolphdescribes flaws in Maccone's arguments. However, the main argument (erasure ofthe observer's memory), which was previously formulated in our work and wasrepeated by Maccone, is correct under the conditions described in this Comment.Moreover, this argument can be used to resolve a reduction paradox (theSchrodinger's Cat paradox) in quantum mechanics. This use is demonstrated inthe second part. In the third part, the synchronisation (decoherence) of timearrows is discussed. In the fourth part, the synchronisation (decoherence) oftime arrows in quantum gravity is considered.
