How does Math relate to Forensic Science?

Answer 1

I'll list a few practical examples of use of math in forensics:

- Blood spatter is a predictable behavior, governed by fluid dynamics. Anything measured is math derived.

- Ballistics; bullets travel, and penetrate objects in very predictable ways, driven by math and physics. An investigator can measure the trajectory, path of travel, etc.

-Statistics come into play in every aspect of crime scene analysis, from DNA to criminal profiling.

Answer 2

Statistics and probability are used extensively in forensic science. It is generally impossible to "prove" that evidence could come only from a specific suspect. It is, however, very possible to use statistics to show the probability it originated from anyone else is so remote that the suspect is the only reasonable person from which it could have come.

One place this is done is in DNA "fingerprinting". It is impractical to type every single gene to create a DNA "match". However, by comparing only a few genes, a sample can be limited to so few possible sources that it almost certainly came from a suspect. That's because each individual gene has a 1/4 probability of matching the gene being compared. However if several genes together are being analyzed, the probability of a match is
(1/4)(1/4)(1/4)(1/4)(1/4) ... or (1/4) to the power of the number of genes being analyzed. A match involving a string of just 10 genes has less than a 1 in a million chance of coming from anyone else, while a match with a string of 15 genes will have less than a 1 in a billion chance of coming from someone else.

Answer 3

Math is used regularly contained in the sphere of forensic technology. Mathematical calculations are used in bloodstain progression perspective determinations, taking pictures reconstructions, scene diagramming, or maybe images. each and every thing from problem-free math to the physics of ballistic arcs are automatically used by crime scene investigators. Your question is a touch obscure. perhaps you'd be extra certain in what you've been searching for.
