National Academy of Sciences Confidence: 80% Arrow up

The National Academy of Sciences (NAS) is a United States nonprofit, non-governmental organization.

NAS is part of the National Academies of Sciences, Engineering, and Medicine, along with the National Academy of Engineering (NAE) and the National Academy of Medicine (NAM).

It publishes nearly 200 books a year on a wide range of topics in the sciences.

The NAP's stated mission is seemingly self-contradictory: to disseminate as widely as possible the works of the National Academies of Sciences, Engineering, and Medicine, and to be financially self-sustaining through sales.

This mission has led to great experimentation in openness regarding online publishing.

The word "medicine" is derived from Latin medicus, meaning "a physician".

Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness.

Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.

Engineering Confidence: 70% Arrow up

Engineering is the application of mathematics and scientific, economic, social, and practical knowledge in order to invent, innovate, design, build, maintain, research, and improve structures, machines, tools, systems, components, materials, processes, solutions, and organizations.
