  • Almost since their inception, the natural sciences, those fields that use the scientific method to study nature, have been divided into two branches: the biological sciences and the physical sciences. In part, this division can be viewed as a convenient social contrivance. However, over time it has also served more functional purposes. Physical scientists, when seeking the fundamental laws, have found it necessary to focus on the simplest of systems—elementary particles, atoms, and molecules—items clearly not alive.

  • Essential oil of Cinnamomum longepetiolatum Costerm. apud Phamh. Obtained by hydro distillation. The essential oil yield was 0.91% in fresh leaves. The chemical composition of this oil was study by GC and GC/MS. Twelve compounds were identified representing 98.8% of this oil with camphor as major constituent (87.5%). Eleven other compounds were found with lower content. The results of this study shows that Cinnamomum longepetiolatum Costerm. apud Phamh. was a new natural source of camphor in Vietnam. ...

  • 21 Unit Two PHYSICS Physics is the major science dealing with the fundamental constituents of the universe, the forces they exert on one another, and the results produced by these forces. Sometimes in modern physics a more sophisticated approach is taken that incorporates elements of the three areas listed above; it relates to the laws of symmetry and conservation, such as those pertaining to energy, momentum, charge, and parity. Physics is closely related to the other natural sciences and, in a sense, encompasses them. ...

  • This proposition is more complicated. The symbol 8 is read “for all”, and the symbol N stands for the set of natural numbers, {0, 1, 2, 3, . . .}. (There is some disagreement about whether 0 is a natural number; in this course, it is.) So this proposition asserts that the final phrase is true for all natural numbers n. That phrase is actually a proposition in its own right:

  • What is Economics? Economics is not a natural science, i.e. it is not concerned with studying the physical world like chemistry, biology. Social sciences are connected with the study of people in society. It is not possible to conduct laboratory experiments, nor is it possible to fully unravel the process of human decisionmaking. “Economics is the study of how we the people engage ourselves in production, distribution and consumption of goods and services in a society.” Normative economics and Positive Economics: Normative economics refers to value judgments, e.g.
