Charles Darwin once said “False facts are highly injurious to the progress of science, for they often endure long; but false views, if supported by some evidence, do little harm, for everyone takes a salutary pleasure in proving their falseness” (Brainy Quote, 2013). Trace evidence is included as one of many studies that helps prove a suspect’s wrongness. Trace evidence is the study that identifies and compares specific types of trace materials that could be transferred during the commission of
There are six general areas in forensic. Theres a medical examiner, crime laboratory analyst,crime scene examiner and a forensic engineer. determining which one you want can be hard, but its easier to talk to someone who does that job. They can tell you different things about the job. Medical Examiner: is the highest pay but you got to be able to cut open bodies.You also have to take 7+ years of college.They also have uncertain work hours. Never going to know when they work and to get called in whenever
vehicle by fitting the chips to the missing section of paint like puzzle pieces. Paint smears from burglary tools can be used to determine which tools were used in the crime (Saferstein, 2009). Combined with other evidence, such as tool marks, forensic scientists can identify specific tools used in a burglary. Collection and Preservation The evidence collector must be very cautious when collecting paint chips. Paint chips are fragile and break easily. Various collection methods exist for different
Forensic scientists work in labs where they examine, identify, and interpret evidence collected in crime scenes. Crime scene investigators collect evidence and pass it to a forensic scientist who uses the items in numerous ways to help catch criminals. Forensic scientists must also record the evidence and any tests ran on it in detail to prove the truth in court. A forensic scientist also has to be able to present his or her physical evidence verbally in court, so a strong communication background

The development of semiconductor materials brought humanity into the Digital Age. Nowadays, people put materials, information, and energy as the three pillars of modern civilization. People pay more attentions on the study of material science and engineering because it can affect humans’ daily lives a lot. This major study in the discovery of new materials, the use of materials, the failure analysis, and the new materials technology have become high-tech technology that has significantly improved and
that contributes to society. The education requirement to become a chemist is a college degree such as B.S in chemistry or a B.A degree in chemistry, you can major in chemistry or a related discipline, such as physical science, life science or engineering. Required courses
chemistry that people pursue to learn more about the composition of the universe, but for now, let us examine the logistics of three of these careers. These three careers involving chemistry are geochemistry, environmental chemistry, and chemical engineering. Firstly, geochemists, according to Prospects, study the amount and distribution of chemical elements in rocks and minerals. Geochemists also study the movement of those elements into soil and water systems. The main purpose of geochemistry is to
1.1.5 Applications of 3D printing Rapid prototyping Rapid improved technologies; diversity materials vary from polymers to living tissue; advocate laws; government subsides; undeveloped market are the primary reasons for the growing of the 3D printing. The constant development of technology has push 3D printing into the mainstream of manufacturing industry. Originally, there was a limit on the traditional models due to prototyping purpose but recently 3D printing has made a fundamental shift towards
