the difference between theory and practice
Practice is the manner in which something is done. It is generally based on facts as well as theories. Many practices have been around for ages and no clear theory is known to be behind them. The term practice is used across the board and is not related to a certain field of work. The practices in all fields of life change from time to time. Image Courtesy: osha.gov.
What is the difference between a physician and a nurse practitioner? The short answer is that doctors study diseases and how to cure them while nurses and nurse practitioners study people and how to heal them. The more detailed answer is that a physician is a person with formal education and training in medicine, i.e. the treatment of diseases using drugs, procedures and/or surgery.
