You know, it's a silo, people in silos. They didn't know that the same thing was happening. So one of them thought about it and said, OK, well, if this is just crystallization that happens automatically out of seawater -- self-assembly -- then why aren't shells infinite in size? What stops the scaling?
是隔行如隔山，彼此缺乏交流。 他们不知道同样的事情也在其他领域发生。 他们当中有个人想了想说，好， 如果这只是结晶现象在海水中自然产生，自我组装， 为什么贝壳不会长到无限大？是什么停止了沉积过程？
