Never has there been a time when an understanding of science has been more important to the well-being of individuals and to the nation than the present. While physics can be a fascinating subject, some of the concepts it presents aren’t always the easiest for students to understand or for teachers to convey to their classes. That’s where the web can come to the rescue. Here you’ll find a list of some great videos that both clearly demonstrate the major ideas of physics for beginners, as well as provide insights in more complex topics for those who are more familiar with the subject matter, like students in engineering.

About Astronomy
Astronomy is written in clear non-technical language, with the occasional touch of humor and a wide range of clarifying illustrations. It has many analogies drawn from everyday life to help non-science majors appreciate, on their own terms, what our modern exploration of the universe is revealing. The book can be used for either a one-semester or two-semester introductory course (bear in mind, you can customize your version and include only those chapters or sections you will be teaching.) It is made available free of charge in electronic form (and low cost in printed form) to students around the world. If you have ever thrown up your hands in despair over the spiraling cost of astronomy textbooks, you owe your students a good look at this one.

Coverage and scope
Astronomy was written, updated, and reviewed by a broad range of astronomers and astronomy educators in a strong community effort. It is designed to meet scope and sequence requirements of introductory astronomy courses nationwide.

Flexibility
Because there are many different ways to teach introductory astronomy, we have made the text as flexible as we could. Math examples are shown in separate sections throughout, so that you can leave out the math or require it as you deem best. Each section of a chapter treats a different aspect of the topic being covered; a number of sections could be omitted in shorter overview courses and can be included where you need more depth. And, as we have already discussed, you can customize the book in a variety of ways that have never been possible in traditional textbooks.

Student-centered focus
This book is written to help students understand the big picture rather than get lost in random factoids to memorize. The language is accessible and inviting. Helpful diagrams and summary tables review and encapsulate the ideas being covered. Each chapter contains interactive group activities you can assign to help students work in teams and pool their knowledge.

Interactive online resources
Interesting “Links to Learning” are scattered throughout the chapters, which direct students to online animations, short videos, or enrichment readings to enhance their learning. Also, the resources listed at the end of each chapter include links to websites and other useful educational videos.

Feature boxes that help students think outside the box
A variety of feature boxes within the chapters connect astronomy to the students’ other subjects and humanize the face of astronomy by highlighting the lives of the men and women who have been key to its progress. Besides the math examples that we’ve already mentioned, the boxes include:

Making Connections. This feature connects the chapter topic to students’ experiences with other fields, from poetry to engineering, popular culture, and natural disasters.
Voyagers in Astronomy. This feature presents brief and engaging biographies of the people behind historically significant discoveries, as well as emerging research.
Astronomy Basics. This feature explains basic science concepts that we often (incorrectly) assume students know from earlier classes.

We all belong to many groups; you’re a member of your sociology class, and you’re a member of your family; you may belong to a political party, sports team, or the crowd watching a sporting event; you’re a citizen of your country, and you’re a part of a generation. You may have a somewhat different role in each group and feel differently in each.

Groups vary in their sizes and formalities, as well as in the levels of attachment between group members, among other things. Within a large group, smaller groups may exist, and each group may behave differently.

At a rock concert, for example, some may enjoy singing along, others prefer to sit and observe, while still others may join in a mosh pit or try crowd surfing. Why do we feel and act differently in different types of social situations? Why might people of a single group exhibit different behaviors in the same situation? Why might people acting similarly not feel connected to others exhibiting the same behavior? These are some of the many questions sociologists ask as they study people and societies.

According to the study conducted by leadership consulting firm Bain & Company, companies like Apple, Google, and Netflix are 40 percent more productive than the average company. Some may think that this is a product of the hiring pool; big companies generally attract a more talented group of recruits. With unique benefits and prowess in the industry, this must be the case. Wrong. Google and Apple have found a way to answer the most fundamental question in management: How do you balance productivity while maintaining employee satisfaction and commitment?

Companies such as Google have approximately the same percentage of “star players” as other companies, but instead of spreading out the talent, they group them dynamically to achieve more throughout the day. This grouping focuses on grouping key players in the most business-critical roles, and is the key to success for the overall company. You’ve heard the saying “You’re only as strong as your weakest link,” and in the case of Apple, there were no weak links, making their productivity extremely high overall. To make matters more complicated, the fast-paced workplace and technology changes, including the diversity of employees and the global marketplace, takes a considerable toll on employee expectations, as do the overall stresses of the business performance. Apple is just one example of a company that figured out one of the pieces to this puzzle, but it is illustrative of what is happening in the workplace all around the globe.

Contemporary managers are witnessing changes in technologies, markets, competition, workforce demographics, employee expectations, and ethical standards. At the heart of these changes is the issue of how to manage people effectively. To attain corporate objectives, each manager must discover how to develop and maintain a workforce that can meet today’s needs while getting ready for tomorrow’s challenges.
Questions such as these point to the issue of effective management. That is, what can managers do to improve both organizational and employee performance? Effective management requires an in-depth knowledge of financial management, marketing research and consumer behavior, accounting and control practices, manufacturing and production techniques, and quantitative methods. In addition, however, effective management requires “people skills.” That is, a good manager must be able to motivate his employees, to lead skillfully, to make appropriate and timely decisions, to communicate effectively, to organize work, to deal with organizational politics, and to work to develop both employees and the organization as a whole. These issues constitute the subject of this course. We shall examine principles of the behavioral sciences that can help managers improve both their own skills and abilities and those of their subordinates in order to enhance organizational performance and effectiveness.
