| 説明 | this isn't really what saliva looks like. I've squeezed it between two glass slides, so its gone into tiny droplets.In vivo it must look different.Often we ask questions of nature. But answering those questions is never straightforward, and it's usually only possible to answer a related question, which we (implicitly, or explictly) assume is roughly equivalent for the task at hand. Looking at things under the microscope isn't the same as seeing them with your own two eyes.That's kind of obvious, and kind of not at all.It's so easy to assume you answered the question you first asked. But of course that's almost never the case. |
