Forensic science (often shortened to forensics) is the application of a broad spectrum of sciences to answer questions of interest to a legal system. This may be in relation to a crime or a civil action. Besides its relevance to a legal system, more generally forensics encompasses the accepted scholarly or scientific methodology and norms under which the facts regarding an event, or an artifact, or some other physical item (such as a corpse) are ascertained as being the case. In that regard the concept is related to the notion of authentication, where by an interest outside of a legal form exists in determining whether an object is what it purports to be, or is alleged as being.
The word forensic comes from the Latin adjective forensis, meaning "of or before the forum". In Roman times, a criminal charge meant presenting the case before a group of public individuals in the forum. Both the person accused of the crime and the accuser would give speeches based on their side of the story. The individual with the best argument and delivery would determine the outcome of the case. This origin is the source of the two modern usages of the word forensic – as a form of legal evidence and as a category of public presentation.
In modern use, the term "forensics" in place of "forensic science" can be considered incorrect as the term "forensic" is effectively a synonym for "legal" or "related to courts". However, the term is now so closely associated with the scientific field that many dictionaries include the meaning that equates the word "forensics" with "forensic science".

The ancient world lacked standardized forensic practices, which aided criminals in escaping punishment. Criminal investigations and trials relied on forced confessions and witness testimony. However, ancient sources contain several accounts of techniques that foreshadow the concepts of forensic science developed centuries later, such as the "Eureka" legend told of Archimedes (287–212 BC).[1]
The first written account of using medicine and entomology to solve (separate) criminal cases is attributed to the book of Hsi Duan Yu(translated as "[Washing Away of Wrongs]"[2][3]), written in Song Dynasty China by Song Ci (宋慈, 1186–1249) in 1248. In one of the accounts, the case of a person murdered with a sickle was solved by a death investigator who instructed everyone to bring his sickle to one location. (He realized it was a sickle by testing various blades on an animal carcass and comparing the wound) Flies, attracted by the smell of blood, eventually gathered on a single sickle. In light of this, the murderer confessed. The book also offered advice on how to distinguish between a drowning (water in the lungs) and strangulation (broken neck cartilage), along with other evidence from examining corpses on determining if a death was caused by murder, suicide, or an accident.[4]
In sixteenth century Europe, medical practitioners in army and university settings began to gather information on cause and manner of death. Ambroise Paré, a French army surgeon, systematically studied the effects of violent death on internal organs. Two Italian surgeons, Fortunato Fidelis and Paolo Zacchia, laid the foundation of modern pathology by studying changes which occurred in the structure of the body as the result of disease. In the late 1700s, writings on these topics began to appear. These included: A Treatise on Forensic Medicine and Public Health by the French physician Fodéré, and The Complete System of Police Medicine by the German medical expert Johann Peter Franck.
In 1776, Swedish chemist Carl Wilhelm Scheele devised a way of detecting arsenous oxide, simple arsenic, in corpses, although only in large quantities. This investigation was expanded, in 1806, by German chemist Valentin Ross, who learned to detect the poison in the walls of a victim's stomach, and by English chemist James Marsh, who used chemical processes to confirm arsenic as the cause of death in an 1836 murder trial.
Two early examples of English forensic science in individual legal proceedings demonstrate the increasing use of logic and procedure in criminal investigations. In 1784, in Lancaster, England, John Toms was tried and convicted for murdering Edward Culshaw with a pistol. When the dead body of Culshaw was examined, a pistol wad (crushed paper used to secure powder and balls in the muzzle) found in his head wound matched perfectly with a torn newspaper found in Toms' pocket. In Warwick, England, in 1816, a farm labourer was tried and convicted of the murder of a young maidservant. She had been drowned in a shallow pool and bore the marks of violent assault. The police found footprints and an impression from corduroy cloth with a sewn patch in the damp earth near the pool. There were also scattered grains of wheat and chaff. The breeches of a farm labourer who had been threshing wheat nearby were examined and corresponded exactly to the impression in the earth near the pool.[5] Later in the 20th century, several British pathologists, Bernard Spilsbury, Francis Camps, Sydney Smith and Keith Simpson would pioneer new forensic science methods in Britain. In 1909 Rodolphe Archibald Reiss founded the first school of forensic science in the world: the "Institut de police scientifique" in the University of Lausanne (UNIL).
Some forensic techniques, believed to be scientifically sound at the time they were used, have turned out later to have much less scientific merit, or none.[6] Some such techniques include:
Litigation science describes analysis or data developed or produced expressly for use in a trial, versus those produced in the course of independent research. This distinction was made by the U.S. 9th Circuit Court of Appeals when evaluating the admissibility of experts.[11]
This uses demonstrative evidence, which is evidence created in preparation of trial by attorneys or paralegals.
Sherlock Holmes, the fictional character created by Sir Arthur Conan Doyle in works produced from 1887 to 1915, used forensic science as one of his investigating methods. Conan Doyle credited the inspiration for Holmes on his teacher at the medical school of the University of Edinburgh, the gifted surgeon and forensic detective Joseph Bell.
Decades later, the comic strip Dick Tracy also featured a detective using a considerable number of forensic methods, although sometimes the methods were more fanciful than actually possible.
Defense attorney Perry Mason occasionally used forensic techniques, both in the novels and television series.
Popular television series focusing on crime detection, including The Mentalist, CSI, Cold Case, Bones, Law & Order, NCIS, Criminal Minds, Silent Witness, Dexter, and Waking the Dead, depict glamorized versions of the activities of 21st century forensic scientists. Some claim these TV shows have changed individuals' expectations of forensic science, an influence termed the "CSI effect".[citation needed]
Non-fiction TV shows such as Forensic Files, The New Detectives, American Justice, and Dayle Hinman's Body of Evidence have also popularized the area of forensic science.
Questions about forensic science, fingerprint evidence and the assumption behind these disciplines have been brought to light in some publications,[12] [13] [14] the latest being an article in the New York Post.[15] The article stated that "No one has proved even the basic assumption: That everyone's fingerprint is unique."[15] The article also stated that "Now such assumptions are being questioned -- and with it may come a radical change in how forensic science is used by police departments and prosecutors."[15]
On June 25, 2009 the Supreme Court issued a 5-to-4 decision in Melendez-Diaz v. Massachusetts stating that crime laboratory reports may not be used against criminal defendants at trial unless the analysts responsible for creating them give testimony and subject themselves to cross-examination. The Supreme Court cited the National Academies report Strengthening Forensic Science in the United States [16] in their decision. Writing for the majority, Justice Antonin Scalia referenced the National Research Council report in his assertion that “Forensic evidence is not uniquely immune from the risk of manipulation.”

“Forensic” comes from the Latin word “forensis” meaning forum. During the time of the Romans, a criminal charge meant presenting the case before a group of public individuals. Both the person accused of the crime and the accuser would give speeches based on their side of the story. The individual with the best argumentation and delivery would determine the outcome of the case. In other words, the person with the best forensic skills would win.

The "Eureka" legend of Archimedes (287-212 BC) can be considered an early account of the use of forensic science. In this case, he determined that a crown was not completely made of gold (as it was fraudulently claimed) by testing its density and buoyancy, as he was not allowed to damage the crown.
The earliest account of fingerprint use to establish identity was during the 7th century. According to Soleiman, an Arabic merchant, a debtor's fingerprints were affixed to a bill, which would then be given to the lender. This bill was legally recognized as proof of the validity of the debt.
The first written account of using medicine and entomology to solve (separate) criminal cases is attributed to the book Xi Yuan Ji Lu (洗冤集錄, translated as "Collected Cases of Injustice Rectified"), written in Song Dynasty China by Song Ci (宋慈, 1186-1249) in 1247.
