Physical Science in Criminology


Physical science is a term used to refer to aspects of natural science. It examines non- living systems. It is directly opposite to life sciences. Physical science foundations lie upon key perceptions and theories, each of which gives explanations on certain aspects of natural behaviors. It is merely the study of the natural world that surrounds us (Shipman, Todd & Wilson, 2007).

Criminal justice refers to interdisciplinary physical science that entails the study of crime and the reactions of the society to crime. It is the study of delinquency and of rules set aside by institutions to enhance fairness and social order. Criminal justice involves the careful investigation of criminology.

Forensic science refers to the use of physical science techniques to solve legal issues. In forensic science, one makes use of physical science to help work out crimes and serve justice. Practitioners thus have a chance to use their knowledge to provide justice.

This paper will discuss the topic of forensic science, as an area of physical science. Its purpose is to show how forensic science can be applied in the field of criminal justice. The relevant background of this report is attributed to the fact that for criminal justice to be honestly served, the crime scene examiner should be neutral.


Criminal justice and forensic science are diverse though often harmonizing disciplines within the field of law enforcement. Criminal justice is a societal field. Its practitioners generate and uphold criminal rules and public procedures. Through physical science, forensic scientists are able to determine evidences associated with DNA, fingerprints and other evidences at crime sites. It is, therefore, clear that though these two are quite diverse, each needs the other. Physical science practitioners operating in the criminal justice system need the systematic competence of the forensic scientist to take criminals into custody.

Physical science is extremely beneficial in criminal justice. It helps in evaluating the physical proofs for relating persons to crime. Through physical science, forensic practitioners analyze the motives which drive individuals to committing a crime. These practitioners are provided with information about the constituents of the criminal justice procedure and steps involved in the criminal justice process. Criminal justice uses physical science to determine all the physical verifications found at the scene where the crime occurs. Forensic scientists are responsible for the systematic processes that supply criminal investigators with proofs for arresting or condemning lawbreakers. They work as analysts in crime laboratories, investigators of crime scenes and forensic engineers (Chappell & Riedel, 2006).

Physical science helps practitioners of criminal justice to understand the concept of criminals, crime development trends and public policy relating to criminal justice. In criminal justice, physical science is applied to the law. Physical scientists look at the proofs and present the outcomes in court. The psychology of the crime is studied. This involves interviewing criminals found guilty so as to establish the driving forces for the committed crimes. Physical science, therefore, encompasses both forensic science and criminology in dealing with issues of criminal justice. Forensic science deals with providing solutions to crimes while criminology deals with the social and mental factors leading to crimes.

The occupation of criminal justice is a captivating field of work. Through physical science, one can learn the ways of becoming a researcher in a crime scene. This is based on the forensic psychology and criminology principles. Practitioners involved in criminal justice apply information gained through physical science to get clues in recognizing the types of crimes done. This information is also applied in the identification of the crime perpetrators and their intentions.

Forensic science puts together information of the physical and ordinary sciences with criminal justice and officially authorized systems. It is a highly rewarding occupation for people thriving on finding solutions to problems, gathering and analyzing data and ensuring public safety. Forensic scientists through physical science are highly learned, well-informed professionals. They help the researchers in a crime scene by gathering evidence through cinematography, sketches and taking real samples that are directly associated with the crime. These can vary from clothing items to hairpieces, body fluids and actual marks found on the body of the victim (Houck, 2008).

Forensic psychology puts into consideration the hidden inspirations that can lead a person to break the law. In this case, physical science helps criminal justice specialists to understand the different kinds of crimes. This helps curb problems related to situations where human emotions claim superiority since this leads to over ruling of common sense.

Physical science has helped professionals in criminal justice to solve crimes appropriately. The level to which each piece of information is collected and evaluated depends on forensic science tactics. Management of criminal justice is known through physical science. The criminal justice personnel must identify and arrest the suspect. For instance, in the criminal justice structure of the United States, an individual is presumed innocent until confirmed guilty by his peers (Fischer & Nickell, 1999).

Forensic evidence gathered through investigation of the crime, and the use of criminology theories helps in criminal justice and suspect interrogation. These are all utilized while building a lawsuit for the judgement. This verifies whether or not the individual blamed for the crime committed the crime. Physical science in this case helps in determining what punishment is just. For instance in criminal justice, a crime committed for a long time may not be treated the same as an impulsive one. Degrees in criminology and forensic science provide criminal justice specialists with knowledge. This assists them to interpret the mental clues of the individual who committed the offense. Through physical science, investigators in crime scene understand that there is some logic at work in the criminals’ mind which is totally different from the rationale of the act.

After the processing of forensic evidence, the person found guilty is taken to the court to undergo trials and may at times face incarceration. Forensic science as a branch of physical science ensures that criminals do not escape punishments. The presence of a fair criminal justice system encourages individuals to overcome temptations of engaging in criminal deals.


Physical science is extremely significant in criminal justice. This is because it enables criminal justice specialists to use their knowledge in science in a manner that allows them to evaluate crime scenes. It also enables them to comprehend how common materials are associated with crime. However, the field is experiencing difficulties due to lack of appropriate information gathering techniques and storage methods. Further research should thus be done to invent new methods for data collection and storage. Physical science has a great significance in people’s everyday life. It is the foundation of the universe. It enlightens people on different measures of physical quantities that are critically important in their lives. This includes volume, mass, momentum and distance. Through these standard measurements, human beings can put their daily activities in order. This has brought human activities together in the world.

We also appreciate physical science through its capability to solve many predicaments facing the world. This entails global warming, decreases in energy, overpopulation and natural calamities. Physical science also assists in crime investigations as demonstrated in this paper. Human beings, therefore, live in a world accustomed by physical science. Deeper appreciation of the societal outcome of physical science is, however, required in scientist education. The significance of physical science in criminal justice and other aspects of daily living can thus not be understated.

The topic of criminal justice needs some improvements to help curb the problems of corruption. Given that criminal justice practitioners are human and vulnerable to the same kinds of passions as the other human beings, there are increased incidences of corruption within this system. This needs to be solved.
