Physical is not the only criterion of truth: there are also psychic truths which can neither be explained nor proved nor contested in any physical way.
“物質”不是唯一的事實標準：還存在心理事實，而且無法以任何的物質方式來解釋、證明、或辯駁它。
Fame is not the goal. The goal is the art.
If you are ever in trouble, don’t try to be brave, just run away.
科學是照亮我們前進道路的火炬。
