soft sciences are less precise than physics because they are hard as they are still theories to which people are researching so as to find a conclusion leaving a room for discussion
Main division would be between the "hard" sciences such as physics or biology and the "softer" sciences, sometimes called the social sciences such as economics or psychology.
Hard work
Science is often thought to have two major divisions, which would be the hard sciences, such as physics, chemistry, astronomy, etc., and the soft sciences such as psychology, sociology, anthropology, etc. The terms hard and soft, in this case, do not refer to the relative degree of difficulty of understanding or advancing those sciences, but they refer rather to the mathematical precision and certainty of the resulting data and conclusions. Physics tends to be much more definite and precise than psychology is.
No
There are many branches of science, which include but are not limited too, the following. These are typically referred to as the "hard sciences"- Astronomy Physics Biology Mathematics Botany Zoology Engineering Chemistry Anatomy The "softer sciences" include your social and behavioral sciences, such as- Psychology Sociology Anthropology Economics Archeology Then there are even more sub-categories.
Economics has a hard time to justify being called a science. A science should have well understood laws, and be capable of explaining phenomena and of predicting outcomes. The latter two have a hard time in economics.
Generally speaking, in US colleges and universities, courses in physics or some other science is not required for a bachelor of arts degree in the social sciences such as history or even in majors such as English or philosophy. A bachelor's degree in science, meaning a bachelor's degree is Physics, a B.S. must require many credits in various hard sciences and in mathematics. With some majors, however, such as economics, then mathematics and statistics courses will normally be required to pass and receive a degree. The aforementioned courses are considered to be sciences.
Social sciences are studies of how people interact. Chemistry- like physics and biology- is part of the "hard" sciences.
Scholar is a better word than scientist for a sociologist, because the term scientist implies a certain freedom from political correctness. The second meaning of the suffix -logy is "the science or study of something," but the "soft sciences" such as sociology and economics are more like a jumbled heap of beliefs and statistics when compared to "hard sciences" like physics or chemistry.
The study of the natural world falls under the broad category 'natural sciences'--these include biology, physics, geology, astronomy, earth sciences, among others. It can also include non-hard sciences, such as history.
pro con list: Hard sciences such as math are easier than soft sciences such as sociology.
I'm going to answer your question with another question. Where did this idea of only TWO branches of science come from? Type in 'science' at www.wikipedia.org and you will see there are many branches of science. However, if you wanted to break into two categories there are the 'hard' sciences (biology, chemistry, physics) and the 'soft' sciences (sociology, economics, psychology). You can another category sometimes referred to as 'formal' science which consists of math, statistics, and logic.
