Medicine

Medicine is the science and art dealing with the maintenance of health, and the prevention or cure of disease. Contemporary medicine applies biomedical research and technology to diagnose and treat injury and disease, through medication, surgery, or some other form of therapy. Although many of their theories were discredited through the centuries, the founder of medicine were the Greek philosophers and physicians Hippocrates, Galen and Avicenna.

Medicine took advantage of the development of other sciences such as physics whose scientists invented optical instruments such as the microscope, and later the x-ray machine. The modern era began with the vaccines discovered by Edward Jenner and Louis Pasteur against smallpox and hydrophobia respectively. Later in 1880, Robert Koch discovered the infectious diseases were transmitted by bacteria.
