Environmental issues are interdisciplinary in character and raise a variety of legal, social, economic, and ethical questions. Science has an important role in enacting, implementing, and enforcing environmental law. However, those conflicting questions are not easy to be resolved only by science. In the 1960s, Rachel Carson had questioned the government's manipulation of science to support the toxicological safety of pesticides, which therefore launched the beginning of the environmental movement in U.S. Even today, the continuing debate on regulatory reform has not yet reached consensus on...

This thesis contains three breakthrough results in condensed matter physics. Firstly, broken reflection symmetry in the hidden-order phase of the heavy-fermion material URu2Si2 is observed for the first time. This represents a significant advance in the understanding of this enigmatic material which has long intrigued the condensed matter community due to its emergent long range order exhibited at low temperatures (the so-called “hidden order”). Secondly and thirdly, a novel collective mode (the chiral spin wave) and a novel composite particle (the chiral exciton) are discovered in the...
