Final Project

Hello, everyone! I'm already beginning my final project of Calculus, so I'm posting all the things the teacher asked us for this entry. I hope you like them. I'm getting very excited with the project. I can't wait to do all the calculations that are needed. I leave you here with all the information that my teacher asked me. I know you will find it very interesting. See you!

1. What is forensic science?

Forensic Science is the areas of science and math applications that allow forensic investigators to discover the cause and time of death of a murdered person and who the murderer is. Also, it is the science that is applied in a court of law to find the culprit of a murder.

2. What kind of evidence can be collected in a murder case?

The kinds of evidence that can be collected in a murder case are:

Ø Bloodstains
Ø Some kind of weapon
Ø Trace Evidence
Ø Material Evidence
-Paint
-Glass
-Fibres
-Plant Material
Ø Clues from the Environment
-Collection
-Basic Comparison
-Seeds and Pollen
-Soil and Dust

3. Why is important to determine the time of death?

It is important to determine the time of death because in this way, police officers and forensic scientists can determine who the murderer is since they can compare it with the alibies of the suspects.

4. What methods are commonly used to find the time of death?

The methods that are commonly used to find the time of death are:

Ø Based on the species of bugs that layed their eggs in the body. Example: Blowflies.
Ø Newton’s Law of Cooling
Ø Radioactive Half Life
Ø Blood Alcohol Content (BAC)

5. What factors are considered in Algor Mortis?

The factors that are considered in Algor Mortis are:

Ø Movement and humidity of the air
Ø Clothing and Coverings
Ø The “size” of the body
Ø Immersion in water

6. How does the environment affect the time of death?

The environment affects the time of death by accelerating the descomposition process. By doing this, all the evidence is destroyed, so the forensic scientists have a hard time detecting the time of death due to humidity, wind, water, changes in the weather, heat, among other factors. Also, because of the acceleration of the descomposition process, many insects and animals will detect the body, so they are more likely to eat parts of the body or vital evidence that might help detect the time of death, like an organ. Therefore, the environment affects in a great deal the time of death.


7. What can you tell about the different methods of temperature reading of the body? Do they make a difference in the results?

Not all of the different methods of temperature reading help to determine the temperature of a death body. This is due to the size of the thermometer. For example, if you try to measure the temperature of a death body via oral or axillary, you won’t get a good result since the thermometer is too small not only in size, but in range, too. So, these two methods are useless for this case. However, the other two reading methods are better, which are via an abdominal stab and per rectum. These two last methods are better; since the heat that is produced in the areas the thermometer is introduced in are hotter than the heat produced in the mouth and in the axila.

What is the goal or main objective of the final project?

The goal or main objective of the final project is to let us see the major role math plays not only in daily life, but also in forensic science to know the cause and time of death of a murdered person, which lets me understand that every thing in daily life is influenced by math even nature. Therefore, math can be applied everywhere and this project shows more applications of it.
