It is the smallest of the true planets. It has a mean radius of 2,440 kilometres which is two fifths of the radius of the Earth. The proximity to the sun makes it difficult to observe Mercury using a terrestrial telescope. Science. Systematic enterprise that builds and organizes knowledge The Universe represented as multiple disk-shaped slices across time, which passes from left to right Modern science is typically divided into three major branches that consist of the natural sciences (e.g., biology, chemistry, and physics), which study nature in the broadest sense; the social sciences (e.g., economics, psychology, and sociology), which study individuals and societies; and the formal sciences (e.g., logic, mathematics, and theoretical computer science), which study abstract concepts.
There is disagreement,[19][20][21] however, on whether the formal sciences actually constitute a science as they do not rely on empirical evidence.[22][20] Disciplines that use existing scientific knowledge for practical purposes, such as engineering and medicine, are described as applied sciences.[23][24][25][26] History Early cultures.
