1. What is the Newton’s Law of Cooling?
It is a method used to calculate the time of death of a person, according to the dropping of the body temperature.
2. What variables in your problem correspond with the variables in the Newton’s Law of Cooling?
The environment, if the body had a disease and the temperature.
3. According to this Law, at what time approximately did the death of the person happened?
7:26 pm.
4. How does the room temperature affect the time of death?
Depending on the original temperature, does the change of temperature happen.
5. How does an illness (e.g. fever) affect the time of death?
Because it means that the person didn’t have the average body temperature, so they have no reference and it will not be exact.
6. How exact is the approximation of the Newton’s Law of Cooling for predicting the time of death?
Not very exact, but it is the closest to the truth.

Murder We Wrote!
What methods are comonly used to find the time of death?
1. The rate method. Measuring the change produced by a process which takes place at a known rate which was either initiated or stopped by the event under investigation, i.e. death. Examples include the amount and distribution of rigor mortis, the change in body temperature, and the degree of putrefaction of the body.2. The concurrence method. Comparing the occurrence of events which took place at known times with the time of occurrence of the event under investigation, i.e. death. For example, a wrist watch stopped by a blow during an assault, the extent of digestion of the last known meal.
What factors are considered in Algor Mortis?
Environment and Temperature of the body.
How does the environment affect the time of death?
Temperature of the environment affects the rate at which the body will decay, so it makes the results vary. 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. This needs to be considered because only like this will you approach the exact time of death.
What can you tell about the different methods of temperature reading of the body? Do they make a difference in the results?
Finding the exact time of death of a body is a very hard thing to do. Although there are different methods for doing this, I believe the more exact one is Algor Mortis, because it considers the temperature of the environment which affects the results you get. If you don't consider this, you are doing it according to an ideal temperature, which in reality will never be the same! :P

Recordemos a Winni!
Ella es Winni! que bonita vd?!
Actualmente, ella vive en un
lugar mejor! pero siempre la 
recordaremos aunque no este
presente! jajajajaja
Ah! y ella me trajò suerte en
el quiz de calculo, vd Linda?!
jajajaaja
FINAL PROJECT!! ;)
Team`s Name: The Pascalitos
Team Members & Roles:
Math expert: Jessica Weihs
Forensic Scientist: Ana Paula Ramos
Media expert: Juan Jose Pacheco
Journalist: Carlos Lopez
Forensic Science: Science applied to the law. It is used to solve murder cases, to find causes of accidents, such as fires, and other legal matters.
Types of Evidence: Biological, samples, impressions, the environment, substances, dental, anthropology, and so on.
Cause and time of death... why is it important to know these? -->
It is important to know these because by knowing these you may find suspects, such as a serial killer, or by the time the victim was murdered. Or maybe the dead person was not murdered, so these will clear your doubts! When, how.. These are the basic things you need to know to solve the whole mystery!
Objective of the Final Project:
The objective of the project is to learn how calculus is applied in real life, which is different to how we`ve been using it in class; and also, it is about what we`ve been seeing in our Man and Science course, so it is an application of the new knowledge acquired! =)

REFLEXION!! =)
"Hacer muchas preguntas puede parecer de imbéciles, pero el que no hace ninguna lo sera toda la vida".
Asì es que ya saben.. ¡hagan muchas preguntas! que si no, seran imbeciles el resto de sus vidas. jajajaja ntc! Pero aclaren sus dudas, ya que, aunque nunca lo van a saber todo, mìnimo se pueden alejar màs de la ignorancia.. (o acercar màs a la sabidurìa) ¡que filosòfica no! jajajaja
