|Quantum mechanics is famous for saying that a tree falling in a forest when there's no one there doesn't make a sound. Quantum mechanics also says that if anyone is listening, it interferes with and changes the tree. And so the famous paradox: how can we know reality if we cannot measure it without distorting it? Disclaimer: I can't measure a board the same way twice, in spite of infinite tries, thus this article is of "particular" interest to me (would that our politicians simply stop distorting!).|
