The scientific study of forensics dates back to the 19th century, but the use of forensic evidence in criminal cases has a long history. In 450 BCE, the Chinese philosopher Confucius noted that “fingerprints could be used for identification.” In 1248 CE, a Chinese book on medicine described how to determine the cause of death by examining a corpse.
Forensic science truly began to develop as a distinct discipline in the late 1800s. French police officer Alphonse Bertillon pioneered the use of anthropometry, or the measurement of bodily features, for identification purposes. Meanwhile, in England, Dr. Henry Faulds developed methods for analyzing fingerprints.
During the early 20th century, American scientists made important contributions to the field of forensic science. In 1908, Calvin Goddard test fired firearms to compare their striae marks with those found at crime scenes. In 1931, LE Ensminger invented chromatography, a process used to separate and analyze chemicals.
As forensic science has evolved, so too has its role in solving crimes. DNA analysis, for example, was first used in a criminal investigation in 1985 and has since become an invaluable tool for law enforcement.
Forensic science is an ever-changing field that continues to grow and evolve as new technologies are developed. It is an exciting and diverse field that offers something for everyone, from detectives to laboratory technicians.
Why Forensic Science An Introduction To Scientific And Investigative Techniques Is Necessary?
Forensic science is the application of scientific methods and principles to matters of law. It is a vital tool in the investigation and prosecution of crime, as well as in the defense against criminal charges.
The forensic science community has long recognized the need for rigorous scientific training and education in order to properly perform its duties. In recent years, there has been an increasing effort to promote best practices in forensic science and to ensure that all practitioners have access to the latest advances in our knowledge.
The study of forensic science can be divided into two main areas: scientific investigation and legal proceedings. Scientific investigations use many of the same techniques as other areas of science, such as chemistry, biology, physics, and engineering. In addition, specialized methods have been developed specifically for use in criminal investigations. Legal proceedings related to forensic science generally fall into two categories: adjudication (determining guilt or innocence) and regulation (establishing rules for handling evidence).
Forensic scientists may work in a variety of settings, including laboratories operated by government agencies or private companies; police departments; medical examiner offices; or as independent consultants. They may also be employed by insurance companies, attorneys, or private individuals who need their expertise for civil litigation or personal injury cases.

Forensic Science: An Introduction to Scientific and Investigative Techniques, Fourth Edition
Forensic science is the study of physical evidence in order to gain an understanding of what happened during a crime or accident. Forensic scientists use a variety of techniques to examine evidence, including DNA analysis, fingerprinting, and ballistics.
Physical evidence can provide crucial clues in solving a crime. However, it is important to remember that physical evidence must be interpreted correctly in order to be useful. Forensic scientists use their training and experience to interpret the meaning of physical evidence.
DNA analysis is a powerful tool that can be used to identify a suspect in a crime. DNA can be obtained from many different sources, including blood, saliva, skin, and hair. Forensic scientists use a variety of techniques to analyze DNA evidence, including PCR and STR.
Fingerprinting is another tool that can be used to identify a suspect. Fingerprints are left behind whenever someone touches an object. Forensic scientists use a variety of techniques to examine fingerprints, including powder and cyanoacrylate fuming.
Ballistics is the study of firearms and ammunition. Forensic scientists use ballistics to examine bullets and firearms. They can use this information to determine the type of firearm used in a crime, as well as the distance from which the shot was fired.

Benefits of Forensic Science An Introduction To Scientific And Investigative Techniques
We all know that forensics is the application of scientific methods and principles to investigate crimes. But what many people don’t realize is that forensic science encompasses much more than just solving murders. In fact, the majority of forensic science disciplines have nothing to do with crime at all!
The term “forensic” comes from the Latin word “forum,” meaning public. Forensic science is simply the application of any scientific discipline in a legal setting. This can include everything from DNA analysis and ballistics testing to psychology and anthropology.
Forensic scientists use their skills to help solve crimes, but they also play an important role in civil cases such as child custody disputes and employment discrimination lawsuits. They may also be called upon to testify in court as expert witnesses.
No matter what area of forensics you are interested in, there are many benefits to pursuing a career in this field. Here are just a few:
1) Exciting Work – If you want a job where you will never be bored, forensic science is the perfect choice! The work is always changing and there are always new challenges to keep you on your toes. You could find yourself working on anything from cold case murders one dayto environmental crimes the next! And because no two cases are ever alike, every day brings something new.
Buying Guide for Best Forensic Science An Introduction To Scientific And Investigative Techniques
Forensic science is the application of science to criminal and civil laws, mainly—on the criminal side—during criminal investigation, as governed by the legal standards of admissible evidence and crime procedure.
