Chemistry and biochemistry are similarly solid -- there are some things we don’t understand about the body, but it is believed that the basic machinery of how cells and molecules interact is known. Slightly apart from these are the new social sciences, which deal with humans and societies.
我们对单一学科都有了非常深入的了解。比如物理，至少是我们普通人能够用到的物理，已经建起了完整的构架。化学和生物化学同样拥有坚实的基础¾虽然人体内还有我们未知的领域，但普遍的看法是我们已经掌握了细胞和分子反应的基本方法。稍微远一点的还有新的社会科学，人和社会是这门学科的研究领域。
