Fingerprints are a reliable means of personal identification. This is the essential explanation for the fact that fingerprints have replaced other methods of identifying people who are reluctant to admit previous arrests. The science of fingerprint identification 5 stands out among all other forensic sciences for many reasons, including the following:. Has served governments worldwide for over a century by providing accurate identification of persons. No two fingerprints have ever been found alike in many billions of human and automated computer comparisons. Fingerprints are the foundation for criminal history confirmation at police agencies worldwide.

Rare Twin Murder Case Echoes Bizarre Fingerprint Origins
A fingerprint is an impression left by the friction ridges of a human finger. The recovery of partial fingerprints from a crime scene is an important method of forensic science. Moisture and grease on a finger result in fingerprints on surfaces such as glass or metal. Deliberate impressions of entire fingerprints can be obtained by ink or other substances transferred from the peaks of friction ridges on the skin to a smooth surface such as paper. Fingerprint records normally contain impressions from the pad on the last joint of fingers and thumbs, though fingerprint cards also typically record portions of lower joint areas of the fingers.
Spectroscopy is the study of the interaction between matter and electromagnetic radiation as a function of the wavelength or frequency of the radiation. Matter waves and acoustic waves can also be considered forms of radiative energy, and recently gravitational waves have been associated with a spectral signature in the context of the Laser Interferometer Gravitational-Wave Observatory LIGO. Spectroscopy, primarily in the electromagnetic spectrum, is a fundamental exploratory tool in the fields of physics , chemistry , and astronomy , allowing the composition, physical structure and electronic structure of matter to be investigated at the atomic, molecular and macro scale, and over astronomical distances.
