First of all, you need to know the job description of scientists in forensic. If you already understand it, you will be able to apply scientific method on how those people do their job by yourselves. Now, answer my question: What is forensics? 🙂

Oh, by the way..talking about forensic, do you know the meaning of this sentence? If I’m not mistaken it says "visum et repertum" and "visum et vivum"..

visum et repertum = investigation in dead body
visum et vivum = investigation in living body

During my "moments"…

@Dr.Stein
ahh…you’re good in those funny language doctor…:lol:

That’s how I learn Biology, never memorizing a term but understanding the meaning of each word from where it belongs 😉

What? Are you sure? 😯 Well, your definition might be correct but do you get the point from it? I don’t 😛

Here an article I found about forensics, I think this will explain you much better so you can understand it and able to apply the scientific method by yourselves 🙂

What is Forensics?

Definition: The study of evidence discovered at a crime scene and used in a court of law.
Context: The author of the Sherlock Holmes stories, Sir Arthur Conan Doyle, was also responsible for furthering the work of forensic science by applying the principles of fingerprinting and firearm identification to criminal investigation work.

Forensic science is any science used for the purposes of the law, and therefore provides impartial scientific evidence for use in the courts of law, and in a criminal investigation and trial. Forensic science is a multidisciplinary subject, drawing principally from chemistry and biology, but also from physics, geology, psychology, social science, etc.

In a typical criminal investigation crime-scene investigators, sometimes known as scene-of-crime officers, will gather material evidence from the crime scene, victim and/or suspect. Forensic scientists will examine these materials to provide scientific evidence to assist in the investigation and court proceedings, and thus work closely with the police. Senior forensic scientists, who usually specialize in one or more of the key forensic disciplines, may be required to attend crime scenes or give evidence in court as impartial expert witnesses.

Examples of forensic science include the use of gas chromatography to identify seized drugs, DNA profiling to help identify a murder suspect from a bloodstain found at the crime scene, and laser Raman spectroscopy to identify microscopic paint fragments.

From examining hair follicles in a lab to scouring a crime scene looking for left behind clues, forensics is a big part of the crime world. It happens every day. It can be a little complicated but great minds have found true suspects. It revolves around evidence. That can include:

Blood samples
Common sense..the blood left behind at a crime scene will reveal a person’s blood type and possibly their identity.

Fingerprints
They are sorted into different categories and therefore reduce the number of suspects.

Footprints/Shoe prints
Strangely enough, footprints and shoe prints in sand and soft ground can tell about a person’s shoe size and what type of shoe they wear. From there, they narrow down the number of people who have bought those type of shoes.

Hair Follicles
A single hair strand left at the scene can show a person’s DNA, which is one of a kind, and could tell you everything about a person.

Vehicles
Sometimes the car at the scene of the crime will try to be hidden, but when found, can be traced by a license number and the make and model to the person who purchased the vehicle.

Dust, dirt, etc
Dirt and dust could provide DNA also.

Semen, body fluids
These important clues, especially in assault cases will determine directly who a criminal is, simply by DNA.

Little things such as cigarette buds, candy wrappers, etc
This is also a good clue to DNA evidence.

DNA: The Basis of Forensics
A revolution has occurred in the last few decades that explains how DNA makes us look like our parents and how a faulty gene can cause disease. This revolution opens the door to curing illness, both hereditary and contracted. The door has also been opened to an ethical debate over the full use of our new knowledge. In the end, curiosity is the reason to learn about DNA. Fittingly, curiosity is the driving force behind science itself.

Gotta love Dr.Stein’s articles

Hehe as I said 😉 🙂

really a good teacher you form Dr Dr…

Bytheway, if you can get it more properly by watching crime investigation programs on discovery channel. These contains some vedeo clipping of scientists doing gas chromatography and DNA fingerprinting. But some scenes of these programs may be psychologically disturbing.

Shrei

Dr.Stein doesn’t like forensics thingy like that…the prove is she said "nah, I’m too lazy…" when I said there’s a CSI movie in the TV programme..
By the way, the CSI in my country had changed into CSI:Miami…I miss the CSI:Las Vegas…

Naah… You might misunderstand me at the time we talked about it 😕 I do like forensics thingy so much, you know I am a big fan of Sherlock Holmes 😉 I am just too lazy to kill the time for watching CSI because it broadcasts after midnight. I hate to wait for hours in the evening from 9-12 pm because I am not a nocturnal. What will I do during that time? I know myself very well, I will asleep during the waiting 🙄 🙁 that’s why I told you that I am lazy for it 😉

you should buy an alarm clock then..make it wake you at 00.00 a.m….:lol:

Alarm clock does not work for me. It fails to wake me up, because when it starts to ring, my hand automatically starts to turn it off 😆 Do miscall to wake me up, phone ringing is better than alarm clock 😉 But I know my hand will make it useless soon 🙄 😆

ck..ck..ck..then you’ve to try Mr.Bean’s way then…
