Medicine (British English; American English) is the science and practice of the diagnosis, treatment, and prevention of disease.

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.

The ampere (SI unit symbol: A, dimension symbol: I), often shortened to "amp", is a unit of electric current.

In the International System of Units (SI) the ampere is one of the seven SI base units.

It is named after André-Marie Ampère (1775–1836), French mathematician and physicist, considered the father of electrodynamics.

Communication (from Latin commūnicāre, meaning "to share") is the act of conveying intended meanings from one entity or group to another through the use of mutually understood signs and semiotic rules.

A patient is any recipient of health care services.

The patient is most often ill or injured and in need of treatment by a advanced practice registered nurse, physiotherapist, physician, physician assistant, psychologist, podiatrist, veterinarian, or other health care provider.

Education is the process of facilitating learning, or the acquisition of knowledge, skills, values, beliefs, and habits.

Educational methods include storytelling, discussion, teaching, training, and directed research.

Education frequently takes place under the guidance of educators, but learners may also educate themselves.

Education can take place in formal or informal settings and any experience that has a formative effect on the way one thinks, feels, or acts may be considered educational.

The methodology of teaching is called pedagogy.
