Quantum Mechanics and the End of Chemistry

One of the great triumphs of 20th century science was the reduction of chemistry to physics via quantum mechanics. By 1927, Wolfgang Pauli was able to explain the structure of the periodic table of elements by means of his Pauli Exclusion Principle, which is a consequence of quantum theory. Now all of chemistry can in principle be reduced to physics.

Forensic Science Careers

There are various specializations one can look forward to as a Forensic Scientist. Some of them are mentioned in the lines to come. Medical examiner is one such field. He requires a medical degree therefore; a residency should be selected that provides a forensic emphasis. A chemistry or biology degree at the undergraduate level is a good majoring option. If at FSU, one takes the crime detection and investigation course as undergraduate electives, one would not have an opportunity for this course at medical school. The forensic odontologist has similar educational requirements as the medical examiner except in dentistry wherein, they generally are dentists who practice as consultants rather than as full-time forensic scientists.

Forensic Science Technicians

Forensic science technicians investigate crimes by collecting and then analyzing physical evidence found at the crime scene. They often specialize in areas such as DNA analysis or firearm examination, performing tests on weapons or on substances such as fiber, glass, hair, tissue, and body fluids to determine their significance to the investigation. Proper collection and storage methods of evidence are important to protect their validity. They also prepare reports to document their findings and the laboratory techniques used, and also provide valuable information and expert opinions to investigators.
