DNA is a good source of evidence for forensic experts, for doctors to identify cancer, recently used for SARS detection, to name a few .\n\nThere are techniques which are used to detect the presence of a specific sequence in a given DNA sample. PCR  or Polymerase Chain Reaction is one of them. here we amplyfy a specific sequence of DNA of interest. if the biological sample contains that DNA sequence then its amplified and can be visualized on a electrophoretic gel. DNA being negativey charged runs on an agorose gel under electric current towards the positive electrode and gets separated based on the size...slower the movement the bulkier the fragment. \n\nforensic experts use this to match DNA samples from site of crime to the suspect. this can also be used in case of paternity disputes, to detect the predisposition of a person to cancer etc etc.\n\nthere are many more techniques which you can search

Think of the perfect murder.  How would you pull it off?  Would you try to make it look like an accident, or make it so there is no evidence (even weapons, an obvious cause of death, etc.).  Next create your hero, and give him some trait that shows how only he could solve the case.  Next, find some way to discover how the crime was pulled off, obviously, no crime is perfect.  This is a pretty good formula to work by, and will give some pretty good results if you're patient.

The universe and all it entails is all brought about by mathematical principles. You can integrate math with virtually any subject. Examples? Here are a few.\nHome economics- Doubling fractions in recipes.\nPhysics- Loaded with math. Use mathematics to prove the laws.\nLanguage and/or Reading- To stimulate comprehension, have students figure out how many of a list of required books they enjoyed by percentage, write a paper on books they have read and maybe even figure out the probabability of the next book to be added to the list using laws of probability. You need, of course to have the difficulty in reading and math to match the other and also the age and ability of the students.\nSocial Studies- Have students figure out percentages of cultures using the english language, per capita population statistics, and probability to estimate growth, or how many different types of money is used in the world, etc.\nWriting- Have students write an essay using words instead of numbers to figure out a determinant (presuming they understand the concept, of course) or stating how to determine percentages or to write out certain laws of mathematics in paragraph form. Written proofs can also be used to demonstrate inductive or deductive reasoning.\nHope the examples help.

most statistics follow a pattern, whether it be linear, quadratic, or whatever. Once you have enough data to establish a pattern, you can accurately predict the remainder of the line.\n\nFor instance, you have a line that looks to be half a parabola. Once it starts going back up, you can be pretty certain of where it's going to be.

The patterns vary from state to state, so there's no one answer.   However, I can give you an example, so that you can create a formula for your state.\n\nSay the state uses 3 letters and then 3 digits.\n\nThe 3 letters each can be one of 26 values, and the 3 digits can each be one of 10 values.\n\nSo the formula would be 26x26x26x10x10x10 or 17,576,000.\n\nOf course, the state could choose to throw out obscene combinations of letters.

Forensic science (often shortened to forensics) is the application of a broad spectrum of sciences to answer questions of interest to the legal system. This may be in relation to a crime or to a civil action. The use of the term "forensics" in place of "forensic science" could be considered incorrect; the term "forensic" is effectively a synonym for "legal" or "related to courts" (from Latin, it means "before the forum"). However, it is now so closely associated with the scientific field that many dictionaries include the meaning given here.\nCriminalistics is the application of various sciences to answer questions relating to examination and comparison of biological evidence, trace evidence, impression evidence (such as fingerprints, shoeprints, and tire tracks), controlled substances, firearms, and other evidence in criminal investigations. Some of the forensic science disciplines are:\nForensic odontology is the study of the uniqueness of dentition.\nForensic toxicology is the study of the effect of drugs and poisons on the human body.\nForensic engineering studies the causes of failure of devices and structures.\nForensic accounting is the study and interpretation of accounting evidence.\nForensic psychology and forensic psychiatry deal with the legal aspects of human behavior.\nForensic anthropology is the application of physical anthropology in a legal setting, usually for the recovery and identification of skeletonized human remains.\nForensic entomology deals with the examination of insects in, on, and around human remains to assist in determination of time or location of death.\nForensic evidence deals with scientific evidence from a crime scene to convict a possible criminal.\nQuestioned document examination is the study and interpretation of evidence that takes the form of document.\n\nCriminal justice refers to the system used by government to maintain social control, enforce laws, and administer justice. Police, courts, and corrections are the primary agencies charged with these responsibilities. Criminal justice is distinct from the field of criminology, which involves the study of crime as a social phenomena, causes of crime, criminal behavior, and other aspects of crime.\nThe pursuit of criminal justice is, like all forms of "justice" or "fairness" or "process", essentially the pursuit of an ideal. Thus, this field has many relations to anthropology, criminology, economics, history, law, political science, psychology, sociology, theology, and ethics.

I would think it is "all of the above".  Forensic science uses physical evidence, it is a science and uses the scientific method to investigate and analyze the evidence in labs, and uses wonderful technology to assist in the analysis.

"Forensics" is a very broad term that just means analytical (generally used in reference to crime scene analysis).  Thus, when looking for information on a Forensic Science you shouldn't just type in "Forensics," because you'll get everything from psychology to odontology.  This site is dedicated to Forensic Chemistry, or analytical chemistry, applied to crime scene analysis.  This would generally include bomb fragment analysis and various other types of chemical residue analysis. \n\nForensic Chemistry and Toxicology generally concerns the detection and characterization of poisons or toxins exhibiting adverse physiological effects. Laboratory methods used in chemical toxicological analysis cover a wide range and may be broadly classified as follows: (1) physical tests (2) crystal tests (3) chemical spot tests (4) spectrophotometric tests (5) chromatographic tests.\n\nThis website should be a great resource: http://www.chemistry.org/portal/a/c/s/1/acsdisplay.html?DOC=vc2%5C3wk%5Cwk3_forensics.html

hi pinku. its the science which deals with guns and bullets. when ever a bullet is fired, it gets scratched by the barrel of the gun in a particular way. it is totaly unique. no other gun can creat the same type of scratches on the bullet. its like the finger print of humans. when ever a crime takes place, it can be found out from a group of guns that from which gun was the bullet fired. and from that gun's licence number, person can be identified. thus, forensic experts use this technique to catch the culprit. \nto do this, a bullet is fired from the gun in the laboratory. it is fired at a certain angle in water tank that prevents it from getting scratched from any other outer obstacle. then the bullet is put under microscope and its photograph is taken. same is done with the bullet which is found on the crime scene. then both the photographs are matched.\nalso, it can tell the distance from which the bullet was fired. when ever a bullet is fired, it gets heated up due to gunpowder burning. this results in burning of human skin when it enters it. so, the greater the distance, less is the burn.\nit can also tell that which gun was used.\n\nhope that i was able to answer your question.\nNOTE:- bhai, kisi ko thok mat dena! hahaha......\n\ngood luck!

Math is used in music everywhere. A lot of the theory behind music deals with math. My theory professor in college was big into using math-like equations to solve theory problems. It can be used in the circle of fiths, finding intervals, chord progressions. About anything! A more recent math/music related thing is Schoenberg's 12 tone system. He uses math and notes to come up with all the different ways to arrange the 12 different notes on the keyboard. You can create a whole matrix just using a certain progression of notes. It's really interesting! To find more information try looking in some college music theory books. Or contact a theory professor at a local college! They could give you lots of good examples.

look into majoring in forensic anthropology (dead people) or forensic archeology (crime scene) search for Forensic Science in your favorite search engine.  I think you're interested in what they do on CSI, right?
