MS meaning in Jobs ?

Mad scientist (also mad doctor or mad professor) is a stock character of a scientist who is described as "mad" or "insane" owing to a combination of unusual or unsettling personality traits and the unabashedly ambitious, taboo or hubristic nature of their experiments. As a motif in fiction, the mad scientist may be villainous (evil genius) or antagonistic, benign or neutral; may be insane, eccentric, or clumsy; and often works with fictional technology or fails to recognise or value common human objections to attempting to play God. Some may have benevolent intentions, even if their actions are dangerous or questionable, which can make them accidental antagonists.
