Summary
Engineering, as a profession, involves transforming science into technology for the benefit of humanity. Mechanical, electrical, civil, and chemical engineering are the big four engineering disciplines, accounting for over half of the bachelor’s-level engineering degrees granted in the United States. Chemical engineering is the branch of engineering dealing with the transformation of species at the…

Employment of Chemical Engineers
The U.S. Department of Labor maintains an extensive database of labor and economic statistics through its Bureau of Labor Statistics (www.bls.gov). The career information about duties, education, training, pay, and current and future prospects for practically any occupation can be found in the Occupational Outlook Handbook (www.bls.gov/ooh) published by the Bureau. The handbook lists the myriad industries—chemicals,…

Roles and Responsibilities of a Chemical Engineer
A chemical engineer performs a number of different tasks in the chemical industry or an organization engaged in chemical business. The tasks and responsibilities of the chemical engineer that are described in this section are based on the concept of engineering as the transformation process from science to technology. Consider the case of manufacturing a…

Defining Chemical Engineering
As with engineering, a clear and concise definition that captures the essence of chemical engineering is not readily available. The American Institute of Chemical Engineers (AIChE), the professional society of chemical engineers in the United States, defines chemical engineers as follows: Individuals who use science and mathematics, especially chemistry, biochemistry, applied mathematics, and engineering principles,…

Engineering Disciplines
The evolution of engineering is essentially a history of civilization. As early humans transitioned from a nomadic existence into settlements, there arose a need for permanent structures and systems for handling water and wastewater demands. Civil engineering developed in response to these needs, and even today one can marvel at the systems developed by engineers…

Engineering and Engineers
Engineering has been considered as the practical application of science for over two centuries. ABET, Inc., formerly the Accreditation Board of Engineering and Technology (www.abet.org), the organization that evaluates and accredits college and university programs in applied science, computing, engineering, and technology in the United States and many other countries, defines engineering as follows: Engineering…

Journals
Some journals that deal with physical chemistry include Historical journals that covered both chemistry and physics include Annales de chimie et de physique (started in 1789, published under the name given here from 1815 to 1914).

History
The term “physical chemistry” was coined by Mikhail Lomonosov in 1752, when he presented a lecture course entitled “A Course in True Physical Chemistry” (Russian: Курс истинной физической химии) before the students of Petersburg University.[9] In the preamble to these lectures he gives the definition: “Physical chemistry is the science that must explain under provisions of physical experiments the reason…

Disciplines
Quantum chemistry, a subfield of physical chemistry especially concerned with the application of quantum mechanics to chemical problems, provides tools to determine how strong and what shape bonds are,[2] how nuclei move, and how light can be absorbed or emitted by a chemical compound.[3] Spectroscopy is the related sub-discipline of physical chemistry which is specifically concerned with the interaction of electromagnetic…

Key concepts
The key concepts of physical chemistry are the ways in which pure physics is applied to chemical problems. One of the key concepts in classical chemistry is that all chemical compounds can be described as groups of atoms bonded together and chemical reactions can be described as the making and breaking of those bonds. Predicting the properties of chemical compounds from a description of…
