“ Thoughts without content are empty, intuitions without concepts are blind. 没有内容的思想是空洞的,没有概念的直觉是盲目的。 Immanuel Kant 康德
“ The increase of scientific knowledge lies not only in the occasional milestones of science, but in the efforts of the very large body of men who with love and devotion observe and study nature. 科学知识的增长不仅在于科学上偶然出现的里程碑式的事件,而且还在于广大热爱自然、专心致志地观察和研究自然的人们的努力。 Polykarp Kusch 波利卡普·库施
