关于大自然，我们能说些什么呢？
What can we say about nature?
摘要：
在这篇文章中，我回顾了语言在现实研究中的重要性，遵循伽利略，玻尔和许多其他人的名言警句。对这些方面的强调有助于我们理解，问现实是“数字”还是“模拟”是没有意义的，但我们必须寻找什么是研究现实某些特定方面的最佳语言。这个问题在前沿科学的情况下尤其明显，比如量子引力，在现有的几种理论（语法）面前，目前既没有观察也没有实验导致建立令人信服的语义。你不会在这里找到一个明确的理论食谱。只是一些想法和问题。
英文摘要：
In this essay, I review the importance of languages in the study of reality, following the well-known aphorisms by Galilei, Bohr and many others. The emphasis on these aspects helps us to understand that it is not meaningful to ask if the reality if "digital" or "analog", but we have to search what is the best language to study some specific aspects of the reality. This problem is particularly felt in the case of frontier science, like quantum gravity, where, in front of several theories (syntaxes) available, there are presently neither observations nor experiments leading to the building of a convincing semantics. You will not find here recipes for a definitive theory. Just thoughts and questions.
