摘要: Although pressure is usually believed to be an always positive quantity, negative states exists since the beginning of Universe and they have been studied Huygens. These are metastable therefore mistakenly thrown out from calculations neglected in experiments as non-existing or unaccessible ones although exist can accessed. Recent theories suggest that normal materials (without any special structure) under auxetic. In this short review paper we would like demonstrate existence discuss limiting for condensed matters (liquids solids).
