Aerospace is the human effort in science, engineering and business to fly in the atmosphere of Earth (aeronautics) and surrounding space (astronautics). Aerospace organizations research, design, manufacture, operate, or maintain aircraft or spacecraft. Aerospace activity is very diverse, with a multitude of commercial, industrial and military applications.
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: Aeronautical engineering and Astronautical Engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering.
Business is the activity of making one's living or making money by producing or buying and selling goods or services. Simply put, it is "any activity or enterprise entered into for profit. It does not mean it is a company, a corporation, partnership, or have any such formal organization, but it can range from a street peddler to General Motors." The term is also often used colloquially (but not by lawyers or public officials) to refer to a company, but this article will not deal with that sense of the word.
Engineering is the creative application of science, mathematical methods, and empirical evidence to the innovation, design, construction, operation and maintenance of structures, machines, materials, devices, systems, processes, and organizations. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering.
Entrepreneurship is the process of designing, launching and running a new business, which is often initially a small business. The people who create these businesses are called entrepreneurs
Management (or managing) is the administration of an organization, whether it is a business, a not-for-profit organization, or government body. Management includes the activities of setting the strategy of an organization and coordinating the efforts of its employees (or of volunteers) to accomplish its objectives through the application of available resources, such as financial, natural, technological, and human resources. The term "management" may also refer to those people who manage an organization.
In business affairs, it is the manner in which even small matters are transacted that often decides man for or against you.

Despatch is the soul of business.
Philip Dormer Stanhope, 4th Earl of Chesterfield (1694-1773). Letter, 5 February 1750.
O brave youth, how good for thee it were couldst thou be made to understand how infinitely precious are thy school years—years when thou hast leisure to grow, when new worlds break in upon thee, and thou fashionest thy being in the light of the ideals of truth and goodness and beauty! If now thou dost not fit thyself to become free and whole, thou shalt, when the doors of this fair mother-house of the mind, close behind thee, be driven into ways that lead to bondage, be compelled to do that which cripples and dwarfs; for the work whereby men gain a livelihood involves mental and moral mutilation, unless it be done in the spirit of religion and culture. Ah! well for thee, canst thou learn while yet there is time that it will profit thee nothing to become the possessor of millions, if the price thou payest is thy manhood.
John Lancaster Spalding, Aphorisms and Reflections (1901), pp. 58-59.
