List of serial killers by number of victims A serial killer is a person who murders two or more people, in two or more separate events over a period of time, for primarily psychological reasons. There are gaps of time between the killings, which may range from a few hours to many years. This list shows serial killers from the 20th century to present day by number of victims (list of serial killers before 1900). In many cases, the exact number of victims assigned to a serial killer is not known, and even if that person is convicted of a few, there can be the possibility that he/she killed many more.

Psychopathy (/saɪˈkɒpəθi/) (or sociopathy /ˈsoʊsiəˌpæθi/) is traditionally defined as a personality disorder characterized by enduring antisocial behavior, diminished empathy and remorse, and disinhibited or bold behavior. It may also be defined as a continuous aspect of personality, representing scores on different personality dimensions found throughout the population in varying combinations. The definition of psychopathy has varied significantly throughout the history of the concept; different definitions continue to be used that are only partly overlapping and sometimes appear contradictory. American psychiatrist Hervey M. Cleckley's work on psychopathy probably influenced the initial diagnostic criteria for antisocial personality reaction/disturbance in the Diagnostic and Statistical Manual of Mental Disorders (DSM), as did American psychologist George E. Partridge's work on sociopathy. Psychopathy
Hare Psychopathy Checklist The Hare Psychopathy Checklist-Revised (PCL-R) is the psychological assessment most commonly used to rate psychopathy. It is a 20-item inventory of perceived personality traits and recorded behaviors, intended to be completed on the basis of a semi-structured interview along with a review of 'collateral information' such as official records. The PCL was originally developed in the 1970s by Canadian psychologist Robert D. Hare for use in psychology experiments, based partly on Hare's work with male offenders and forensic inmates in Vancouver, and partly on an influential clinical profile by American psychiatrist Hervey M. Cleckley first published in 1941. A revised version, renamed the Hare PCL, was drafted in 1985 and released in 1991 as the PCL-R, with an updated second edition in 2003. It comprises a manual, a rating booklet, scoring forms and interview guides.
Antisocial (or dissocial) personality disorder is characterized by a pervasive pattern of disregard for, or violation of, the rights of others. There may be an impoverished moral sense or conscience and a history of crime, legal problems, impulsive and aggressive behavior. Antisocial personality disorder (ASPD) is the name of the disorder as defined in the Diagnostic and Statistical Manual (DSM). Dissocial personality disorder is the name of a similar or equivalent concept defined in the International Statistical Classification of Diseases and Related Health Problems (ICD), where it states that the diagnosis includes antisocial personality disorder. Both manuals have similar but not identical criteria. Both have also stated that their diagnoses have been referred to, or include what is referred to, as psychopathy or sociopathy, though distinctions are sometimes made. Diagnosis Antisocial personality disorder
Coordinates: Location of Salar de Uyuni Salar de Uyuni viewed from space, with Salar de Coipasa in the top left corner The Salar was formed as a result of transformations between several prehistoric lakes. It is covered by a few meters of salt crust, which has an extraordinary flatness with the average altitude variations within one meter over the entire area of the Salar. The crust serves as a source of salt and covers a pool of brine, which is exceptionally rich in lithium. Salar de Uyuni
There is often an implicit assumption that daughter communities innovate and the mother community keeps the original speech. But in the 400 years since London and New York began to diverge in accent, both have undergone 400 years of evolution. A mother community (such as the homeland, England) being large and its colonies being small (at first), you might expect different rates of propagation of change. The origins of the American accent (idea)

Encephalitis lethargica Encephalitis lethargica or von Economo disease is an atypical form of encephalitis. Also known as "sleepy sickness" (though different from the sleeping sickness transmitted by the tsetse fly), it was first described by the neurologist Constantin von Economo in 1917. The disease attacks the brain, leaving some victims in a statue-like condition, speechless and motionless. Between 1915 and 1926, an epidemic of encephalitis lethargica spread around the world; no recurrence of the epidemic has since been reported, though isolated cases continue to occur. Symptoms Encephalitis lethargica is characterized by high fever, sore throat, headache, lethargy, double vision, delayed physical and mental response, sleep inversion and catatonia. In severe cases, patients may enter a coma-like state (akinetic mutism).
A meme (/ˈmiːm/ meem) is "an idea, behavior, or style that spreads from person to person within a culture." A meme acts as a unit for carrying cultural ideas, symbols, or practices that can be transmitted from one mind to another through writing, speech, gestures, rituals, or other imitable phenomena with a mimicked theme. Supporters of the concept regard memes as cultural analogues to genes in that they self-replicate, mutate, and respond to selective pressures. The word meme is a shortening (modeled on gene) of mimeme (from Ancient Greek μίμημα Greek pronunciation: [míːmɛːma] mīmēma, "imitated thing", from μιμεῖσθαι mimeisthai, "to imitate", from μῖμος mimos "mime") and it was coined by the British evolutionary biologist Richard Dawkins in The Selfish Gene (1976) as a concept for discussion of evolutionary principles in explaining the spread of ideas and cultural phenomena.

The experimenter (E) orders the teacher (T), the subject of the experiment, to give what the latter believes are painful electric shocks to a learner (L), who is actually an actor and confederate. The subject believes that for each wrong answer, the learner was receiving actual electric shocks, though in reality there were no such punishments. Being separated from the subject, the confederate set up a tape recorder integrated with the electro-shock generator, which played pre-recorded sounds for each shock level. The experiments began in July 1961, three months after the start of the trial of German Nazi war criminal Adolf Eichmann in Jerusalem. Milgram devised his psychological study to answer the popular question at that particular time: "Could it be that Eichmann and his million accomplices in the Holocaust were just following orders? Milgram experiment
The papacy has been surrounded by numerous legends. Among the most famous are the claims that the Papal Tiara bears the number of the beast inscriptions, that a woman was once elected pope, or that the current pope will be the last Pope. The two former claims have been independently determined to be false. Legends surrounding the papacy
