Technology (Greek technologia (τεχνολογία) < techne (τέχνη) "craft" + -ologia (-ολογία) "science or discipline") is the application of developments in science and engineering to benefit humanity. It may be defined as: "Solutions for real human problems by the development and application of tools, machines, materials, goods, or information in the form of skills, knowledge, processes, blueprints, plans, diagrams, models, formulae, tables, engineering designs, specifications, manuals, or instructions."

Gregor Mendel
Gregor Johann Mendel (July 20, 1822 – January 6, 1884) was an Augustinian priest and scientist, and is often called the father of genetics for his study of the inheritance of certain traits in pea plants. Mendel showed that the inheritance of these traits follows particular laws, which were later named after him. The significance of Mendel's work was not recognized until the turn of the 20th century. Its rediscovery formed the foundation of the modern science of genetics.

Mendel was born into an ethnic German family in Heinzendorf bei Odrau, Austrian Silesia, Austrian Empire (now Hynčice, Czech Republic), and was baptized two days later. He was the son of Anton and Rosine Mendel, and had one older sister and one younger. They lived and worked on a farm which had been owned by the Mendel family for at least 130 years. During his childhood, Mendel worked as a gardener, studied beekeeping, and as a young man attended the Philosophical Institute in Olomouc in 1840–1843. Upon recommendation of his physics teacher Friedrich Franz, he entered the Augustinian Abbey of St Thomas in Brno in 1843. Born Johann Mendel, he took the name Gregor upon entering monastic life. In 1851 he was sent to the University of Vienna to study, returning to his abbey in 1853 as a teacher, principally of physics.

The year was 1851 when Gregor Mendel, a young priest from a monastery in Central Europe, entered the University of Vienna to study the mathemetics and science. Mendel cared for the monastery's garden, where he grew hundreds of pea plants. He became curious as of why some of the plants had different physical characteristics ( traits ) Some grew small, others grew tall. Some plants produced green seeds, while some produced yellow seeds. Sometimes, however, the pea plants had different traits than their parents. For more than 10 years Mendel experimented with thousands of pea plants to understand the process of heredity.
