Abstract
By and large, the status of the sciences of nature or natural sciences such as physics or chemistry goes unquestioned. They conform to the different criteria put forward by epistemologists and qualify as sciences. This does not mean that physicists or chemists never encounter epistemological problems: it just means that such disciplines are as scientific as a discipline can get. The same can be said of mathematics which is not strictly speaking, a "natural science". We analyze the characteristics of the natural science and the various elements that constitute it.
