who came up with the butterfly effect theory
Butterfly effect The term itself was coined by Edward Lorenz, and is derived from the metaphorical example of the details of a tornado (exact time of formation, exact path taken) being influenced by minor perturbations such as the flapping of the wings of a distant butterfly several weeks earlier. Lorenz discovered the effect when he observed that runs of his weather model with initial condition data that was rounded in a seemingly inconsequential manner would fail to reproduce the results of runs with the unrounded initial condition data. A very small change in initial conditions had created a significantly different outcome. [3]
Criminology Cesare Lombroso (1835-1909), an Italian sociologist working in the late 19th century, is often called "the father of criminology."[4] He was one of the key contributors to biological positivism and founded the Italian school of criminology.[5] Lombroso took a scientific approach, insisting on empirical evidence for studying crime.[6] He suggested physiological traits such as the measurements of cheek bones or hairline, or a cleft palate (the belief was this was a throwbacks to Neanderthals) could indicate "atavistic" criminal tendencies. This approach, whose influence came via the theory of phrenology and by Charles Darwin's theory of evolution, has been superseded. Enrico Ferri, a student of Lombroso, believed social as well as biological factors played a role, and believed criminals should not be held responsible when factors causing their criminality were beyond their control. Criminologists have since rejected Lombroso's biological theories, with control groups not used in his studies.[7][8]
