1. What is the Newton’s Law of Cooling?

It is a "satisfactory" approximation to the surface temperature of an object changes at a rate proportional to its relative temperature. That is, the difference between its temperature and the temperature of the surrounding enviroment.

2. What variables in your problem correspond with the variables in the Newton’s Law of Cooling?

The variables of time, and temperature of the body and the surrounding.

3. According to this Law, at what time approximately the death happened?

-With a room temperature at 70°F

1) Healthy/98.7°F - Time Of Death: 8:54:4 P.M.

2) Regular/99.5°F - Time Of Death: 8:50:4 P.M.

3)Sick/101°F - Time Of Death: 8:43:4 P.M.

-With a room temperature at75°F,

1) Healthy/98.7°F - Time of Death: 8:55:7 P.M.

2) Regular/99.5°F - Time of Death: 8:51:2 P.M.

3) Sick/101°F - Time of Death: 8:42:4 P.M.

4. How does the room temperature affect the time of death?

Acording to the law of cooling, the room temperature affects the body because ther is a difference between the temperatures of the body and the room and this makes that the both temperatures make an equilibrium by staying in touch one with another.

5. How does an illness (e.g. fever) affect the time of death?

An illness shall change the temperature of the body because all the reactions that the illnes produces.

6. How exact is the approximation of the Newton’s Law of Cooling for predicting the time of death?

It is satisfactory approximate

Murder We Wrote...

4. What methods are commonly used to find the time of death?
Rule of Thumb, Rate Method and Concurrence Method, Algor Mortis, Henssge Method, Rigor Mortis

5. What factors are considered in Algor Mortis?
The temperate of climate since in tropical regions there may be a minimal fall in body temperature post mortem and in some extreme climates, the body temperature may even rise after death.

6. How does the environment affect the time of death?
The temperature affects directly the corpse. Newton's law of cooling states that the rate of cooling of a body is determined by the difference between the temperature of the body and that of its environment.

7. What can you tell about the different methods of temperature reading of the body? Do they make a difference in the results?
They are all different, because all of them are focused in specific parts, and consider other things.

Questions:

1. What is forensic science?
Is a science that applies other sciences to get answers of interest to the legal system.

2. What kind of evidence can be collected in a murder case?
Biological evidence, trace evidence, impression evidence (such as fingerprints, footwear impressions, and tire tracks), controlled substances, firearms, and other evidence in criminal investigations.

3. Why is important to determine the time of death?
Because with all the evidence, the only that is needed to prove is at what hour did the murder happened. Place the guilty in the crime scene at the right time.

4. Goal:
We think that the main objective of this project, is to use our creativity and knowledge to understand the applied mathematics in a very effective use, the "forensic science". That way, we need to work like a team, and with different roles, also we're going to show our cinematographic skills and editing skills too. We are excited waiting for start filming ;)! We think its going to be a very funny project and we already have many good ideas.
