This is a calculus-based physics textbook meant for the type of freshman survey course taken by engineering and physical science majors, or for AP Physics C. It uses a nontraditional order of topics, with energy coming before force. For instructors who prefer the traditional sequence, there is a drop-in replacement for ch. 0-4, Mechanics, that covers force before energy. My text for the type of course usually taken by biology majors is Light and Matter.

We touch things every day: a coffee cup, a car door, a computer keyboard. Each time we do, it is likely that we leave behind our unique signature- in our fingerprints.

No two people have exactly the same fingerprints. Even identical twins, with identical DNA, have different fingerprints. This uniqueness allows fingerprints to be used in all sorts of ways, including for background checks, biometric security, mass disaster identification, and of course, in criminal situations.

Fingerprint analysis has been used to identify suspects and solve crimes for more than 100 years, and it remains an extremely valuable took for law enforcement. Once of the more important uses for fingerprints is to help investigators link one crime scene to another involving the same person. Fingerprint identification also helps investigators to track a criminal's record, their previous arrests and convictions, to aid in sentencing, probation, parole and pardoning decisions.

This a textbook on special relativity, aimed at undergraduates who have already completed a freshman survey course. The treatment of electromagnetism assumes previous exposure to Maxwell's equations in integral form, but no knowledge of vector calculus.

Strategies for Academic Success accompanies the online first-year University of Saskatchewan Arts and Science course by the same name. The textbook has a reader-friendly format arranged to help you develop the essential skills and provide the information you need to succeed in university.

In this strategy guide, you will learn how to organize students and texts to allow for learning that meets the diverse needs of students but keeps student groups flexible.

The research that originally gave credibility to the jigsaw approach—creating heterogeneous groups of students, diving them into new groups to become expert on a topic, and then returning them to their home groups—touted its value as a means of creating positive interdependence in the classroom and improving students’ attitudes toward school and each other.

With "Sustainability: A Comprehensive Foundation", first and second-year college students are introduced to this expanding new field, comprehensively exploring the essential concepts from every branch of knowldege Đ including engineering and the applied arts, natural and social sciences, and the humanities. As sustainability is a multi-disciplinary area of study, the text is the product of multiple authors drawn from the diverse faculty of the University of Illinois: each chapter is written by a recognized expert in the field. This text is designed to introduce the reader to the essential concepts of sustainability. This subject is of vital importance seeking as it does to uncover the principles of the long-term welfare of all the peoples of the planet but is only peripherally served by existing college textbooks.

Taking the Mystery Out of Illinois School Finance was written by Thomas A. Kersten, professor of Educational Leadership at Roosevelt University in Chicago, Illinois. This textbook was developed over several years and is designed to explain the key principles of Illinois school finance in a way that graduate students in educational administration programs, teachers, school board members, parents, building-level school administrators, and other interested citizens can grasp the essential content without getting bogged down in excessive financial detail. Only by understanding the basics of Illinois school finance, can school administrators, board members, and other constituents make informed decisions.

This book is about complexity science, data structures and algorithms, intermediate programming in Python, and the philosophy of science. This book focuses on discrete models, which include graphs, cellular automata, and agent-based models. They are often characterized by structure, rules and transitions rather than by equations. They tend to be more abstract than continuous models; in some cases there is no direct correspondence between the model and a physical system.

The examples and supporting code for this book are in Python. You should know core Python and you should be familiar with object-oriented features, at least using objects if not defining your own. If you are not already familiar with Python, you might want to start with my other book, Think Python, which is an introduction to Python for people who have never programmed, or Mark Lutz’s Learning Python, which might be better for people with programming experience.

Think Java is an introduction to Java programming for beginners. It is tailored for students preparing for the Computer Science Advanced Placement (AP) Exam, but it is for anyone who wants to learn Java.

Think OS is an introduction to Operating Systems for programmers. In many computer science programs, Operating Systems is an advanced topic. By the time students take it, they usually know how to program in C, and they have probably taken a class in Computer Architecture. Usually the goal of the class is to expose students to the design and implementation of operating systems, with the implied assumption that some of them will do research in this area, or write part of an OS.

The goal of this book is to teach you to think like a computer scientist. This way of thinking combines some of the best features of mathematics, engineering, and natural science. Like mathematicians, computer scientists use formal languages to denote ideas (specifically computations). Like engineers, they design things, assembling components into systems and evaluating tradeoffs among alternatives. Like scientists, they observe the behavior of complex systems, form hypotheses, and test predictions.

Think Python is an introduction to Python programming for beginners. It starts with basic concepts of programming, and is carefully designed to define all terms when they are first used and to develop each new concept in a logical progression. Larger pieces, like recursion and object-oriented programming are divided into a sequence of smaller steps and introduced over the course of several chapters.

This book is a practical guide to adapting or creating open textbooks using the PressBooks platform. It is continually evolving as new information, practices and processes are developed. The primary audience for this book are faculty and post-secondary instructors in Saskatchewan, Canada who are developing, adapting or adopting open textbooks at the University of Saskatchewan. However, there may be content within this book that is useful to others working on similar Open Educational Resource initiatives.

Diagnostic Imaging principles and concepts are augmented by the presentation of imaging for common clinical conditions. Guiding principles related to minimizing radiation exposure and requesting the most appropriate imaging examination is addressed. Static images are enhanced by the ability to access images stored and displayed on an Html-5 compatible, Dicom image viewer that simulates a simple Picture Archive and Communication system (PACS). Users can also access other imaging from the Dicom viewer (ODIN), beyond the basic curriculum provided, to further advance their experience with viewing diagnostic imaging pathologies.This book is also available in three other digital formats: ePUB (for Nook, iBooks, Kobo etc.), PDF (regular print), PDF (large print).

Most of us will have heard the term Ballistics at some time or other - more often than not when we have been watching fictionalised accounts of police work on television or in the cinema.

What is Ballistics?
Ballistics is the area of Forensic Science that deals with firearms; how they are used, why they are used and why they are used frequently in the practice of murder.

What many people do not realise is that when a person is shot the wound and the condition of the victim can tell a lot about the nature of the weapon that has been used. Indeed if the weapon has been left at the scene of the crime - which sometimes happens when the perpetrator panics - the weapon itself can go a long way to providing valuable information as to the kind of person who has committed the offence.

Identifying a Weapon
Most guns have their own unique identifying features and even if the gun has not been left at the crime scene many degrees of information can be determined from the bullet, the nature of the wound and any residue that is left around it.

Bullets contain a mixture of gunpowder and cordite and these leave burn marks on the skin of the individual either wounded or killed, they also leave a fine residue on the fingers and hands of the individual firing the gun. These burn marks can signify closeness of the victim to the perpetrator, kind of weapon and also if the weapon has had any modifications made to it. Some weapons have been disarmed by having the firing pins and mechanisms removed but there are individuals who can 'reactivate' these weapons for use again.
Also, each weapon's barrel contains small ligatures and grooves, which, when a bullet is fired from them, make marks on the shell casing, which can be used as a means of identifying the make and model of gun if these shell casings are found at the scene.
It is also worth noting that an automatic - or semi automatic weapon - will expel shell casings as the weapon fires a round whereas a revolver will fire the round but retain the shell casing within the barrel.

Investigating
The field of ballistics is able to identify rifling patterns, marks made by using suppressors (silencers), shell casings, powder burn and many other different areas relating to the use of firearms and the evidence they leave behind.

Indeed most ballistics experts will be able to tell you the particular weapon simply by the sound of it being fired. They will also be able to carry out distance and depth tests which include firing rounds of ammunition into water, sand and other substances to determine how close a person would have to be to receive a life threatening wound from a gun.
Ballistics is a very important part of the world of Forensic Science and much of its evidence is used in criminal proceedings. In some cases the use of ballistics research can prove a link between many different crimes carried out over a lengthy period of time. This is also an important function of the ballistics team as many weapons are passed and sold on between criminals during their life cycle.
