This is not a typical e-book; it is a free, web-based, open-source “textbook” available to anyone interested in using mapping tools to create maps. This e-text focuses primarily on Geographic Information Systems (GIS)—a geospatial technology that enables you to create spatial databases, analyze spatial patterns, and produce maps that communicate more effectively. While this GIS textbook is principally an introduction to GIS, most of the chapter’s concepts are applicable to other geotechnologies including remote sensing, global positioning systems (GPS), Internet mapping, and virtual globes.

Creating good maps and analyzing spatial data is a time consuming and challenging practice, but recently, a new set of powerful mapping tools has enabled almost anyone with a computer to make maps easily and to perform at least some low-level analyses. The results, however, are not encouraging. Most of the new mapmakers do not have adequate training in mapping concepts and spatial analysis principles, and their maps are often improperly designed and do not communicate easily nor effectively. This e-text—GIS Commons—seeks to help you analyze spatial data and communicate more effectively. In short, GIS education is our goal.

This resource was created as part of a project to develop open-access lab notes for the University of Ottawa's "GIS and the Digital Earth" course and its French counterpart "SIG et la Terre numérique". It contains lab notes for five labs with exercises for this introductory course, as well as the data needed for students to work through the labs. All labs are based on ArcGIS Pro, and requires students to have access to this software.

Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, change gravity, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other.

This course focuses on contributions of biochemistry toward an understanding of the structure and functioning of organisms, tissues, and cells. Topics include:

Chemistry and functions of constituents of cells and tissues and the chemical and physical-chemical basis for the structures of nucleic acids, proteins, and carbohydrates.
Basic enzymology and biochemical reaction mechanisms involved in macromolecular synthesis and degradation, signaling, transport, and movement.
General metabolism of carbohydrates, fats, and nitrogen-containing materials such as amino acids, proteins, and related compounds.

NOTE: The first half of this course, taught by Prof. Yaffe, is available on the MITx platform as 7.05x Biochemistry: Biomolecules, Methods, and Mechanisms. This OCW website provides content primarily from the second half with Prof. Vander Heiden, which focuses on metabolism.

This course deals with inorganic and physical chemistry. The study of the structure of atoms, the periodic nature of the elements, and the examination of the relationship of energy and the elements to form compounds and the three physical states of matter will be investigated.

Generate electricity with a bar magnet! Discover the physics behind the phenomena by exploring magnets and how you can use them to make a bulb light.

Essentials of Geographic Information Systems integrates key concepts behind the technology with practical concerns and real-world applications. Recognizing that many potential GIS users are nonspecialists or may only need a few maps, this book is designed to be accessible, pragmatic, and concise. Essentials of Geographic Information Systems also illustrates how GIS is used to ask questions, inform choices, and guide policy. From the melting of the polar ice caps to privacy issues associated with mapping, this book provides a gentle, yet substantive, introduction to the use and application of digital maps, mapping, and GIS.

Die Postergalerie im "Global Change Poster Explorer" entstand im Rahmen des Master Moduls "Schauplätze des Globalen Wandels" der Physischen Geographie im Wintersemester 2019/2020. Von Prof. Dr. Rüdiger Glaser wurden die Poster konzeptionell und inhaltlich betreut, von Michael Kahle wurde die Programmierung und die Veröffentlichung auf FreiDok übernommen. Dieses Format wurde mittlerweile für die Ringvorlesung Globaler Wandel übernommen. An dieser Ringvorlesung sind mehrere Dozierende der Geographie in Freiburg beteiligt. Entsprechend vielfältig sind die Themen, Ansätze und Orte. Die Poster können nach Themen, Orten, Konzepten und verschiedenen Landschaftstypen gefiltert oder auf der Übersichtskarte lokalisiert werden.

The poster gallery "Global Change Poster Explorer" was initiated as part of the Master module "Hot Spots of Global Change" in Physical Geography in the winter term in 2019/2020. Prof. Dr. Rüdiger Glaser developed the concept and supervised the content of the posters, and Michael Kahle was responsible for programming and publication on FreiDok. This format has since been adopted for the Global Change Lecture Series. Several lecturers of geography in Freiburg are involved in this lecture series. The topics, approaches and locations are correspondingly diverse. Posters can be filtered by theme, location, concept, and various landscape types or located on the overview map.

Geography 431 is designed to further understanding of the natural processes of aquatic ecosystems, management of water resources, and threats to sustaining water quantity. Develop awareness and appreciation of the perspectives about water as a precious resource, commodity, and sometimes hazard. Learn how and why water is distributed unevenly around the Earth. Examine how resource management decisions are strongly related to water availability, quantity, and quality. The course examines water resources management; dams and dam removal; provision of safe potable water; threats to water quantity and quality; land use changes; the water economy; water laws and policy; institutions for water management at the global, national, regional, and local scale; and issues of water security and climate change.

Students will look up an address (either of their choosing or instructor-provided) and assess the geologic characteristics and vulnerability of that location. Students will utilize datasets about geologic issues/hazards to learn more about how different geologic processes affect the location.

How does a lens form an image? See how light rays are refracted by a lens. Watch how the image changes when you adjust the focal length of the lens, move the object, move the lens, or move the screen.

Motivated by questions in cosmology, the open-content text Geometry with an Introduction to Cosmic Topology uses Mobius transformations to develop hyperbolic, elliptic, and Euclidean geometry - three possibilities for the global geometry of the universe.

The text, written for students who have taken vector calculus, also explores the interplay between the shape of a space and the type of geometry it admits. Geometry is suitable for a semester course in non-Euclidean geometry or as a guide to independent study, with over 200 exercises and several essays on topics including the history of geometry, parallax and curvature, and research aimed at determining the shape of the universe.

Students are introduced to gear transmissions and gear ratios using LEGO MINDSTORMS(TM) NXT robots, gears and software. They discover how gears work and how they can be used to adjust a vehicle's power. Specifically, they learn how to build the transmission part of a vehicle by designing gear trains with different gear ratios. Students quickly recognize that some tasks require vehicle speed while others are more suited for vehicle power. They are introduced to torque, which is a twisting force, and to speed the two traits of all rotating engines, including mobile robots using gears, bicycles and automobiles. Once students learn the principles behind gear ratios, they are put to the test in two simple design activities that illustrate the mechanical advantages of gear ratios. The "robot race" is better suited for a quicker robot while the "robot push" calls for a more powerful robot. A worksheet and post-activity quiz verify that students understand the concepts, including the tradeoff between torque and speed.

Lesson Overview Each student will write a journal entry about how motivation and perspective influence a dream. In addition, students will focus on how these influences can lead to a flawed dream. Students will read, analyze, and discuss the poem, “Dreams” by Langston Hughes, Martin Luther King’s “I Have a Dream” speech, excerpts from Chasing Lincoln’s Killer—Introduction—From 1861 through 1865 and pages 138-139, and the article, “Booth’s Reason for Assassination” by Christopher Hamner. Students will write an  essay about John Wilkes Booth. In successive days, students will draft, revise, edit, and publish their essays. Image source:  "Dream" by EvelynGiggles on Flickr.com. Licensed with CC-BY-2.0

In this lesson, students will read chapters 9-14 in James L. Swanson’s, Chasing Lincoln's Killer to analyze and discuss how Swanson presents the repercussions of John Wilke’s Booth’s assassination of President Abraham Lincoln.  Students will also compare Swanson’s account to a multimedia version of Booth’s escape after the assassination of Lincoln. Cover image source: "John Wilkes Booth Wanted Poster" edited from the original from the Library of Congress at https://www.loc.gov/item/96521960/
