The overall goal of the authors with General Chemistry: Principles, Patterns, and Applications was to produce a text that introduces the students to the relevance and excitement of chemistry. Although much of first-year chemistry is taught as a service course, Bruce and Patricia feel there is no reason that the intrinsic excitement and potential of chemistry cannot be the focal point of the text and the course. So, they emphasize the positive aspects of chemistry and its relationship to students' lives, which requires bringing in applications early and often. In addition, the authors feel that many first year chemistry students have an enthusiasm for biologically and medically relevant topics, so they use an integrated approach in their text that includes explicit discussions of biological and environmental applications of chemistry. Topics relevant to materials science are also introduced to meet the more specific needs of engineering students. To facilitate integration of such material, simple organic structures, nomenclature, and reactions are introduced very early in the text, and both organic and inorganic examples are used wherever possible. This approach emphasizes the distinctions between ionic and covalent bonding, thus enhancing the students' chance of success in the organic chemistry course that traditionally follows general chemistry. Finally, the authors made a conscious effort to treat material that has traditionally been relegated to boxes, and thus perhaps perceived as peripheral by the students, by incorporating it into the text to serve as a learning tool. To begin the discussion of chemistry rapidly, the traditional first chapter introducing units, significant figures, conversion factors, dimensional analysis, and so on, has been reorganized. The material has been placed in the chapters where the relevant concepts are first introduced, thus providing three advantages: Eliminates the tedium of the traditional approach, which introduces mathematical operations at the outset, and thus avoids the perception that chemistry is a mathematics course; Avoids the early introduction of operations such as logarithms and exponents, which are typically not encountered again for several chapters and may easily be forgotten when they are needed; and Provides a review for those students who have already had relatively sophisticated high school chemistry and math courses, although the sections are designed primarily for students unfamiliar with the topic. Consider this text for your course if you are interested in In summary, a text that represents a step in the evolution of general chemistry texts toward one that reflects the increasing overlap between chemistry and other disciplines. Most importantly, if you want a text that discusses exciting and relevant aspects of biological, environmental, and materials science that are usually relegated to the last few chapters, in a format that allows the you to tailor the emphasis to the needs of the class.

As part of the BBC World Service, BBC Learning English has been teaching English to global audiences since 1943, offering free audio, video and text materials to learners around the world. From our mobile English courses in Bangladesh and Latin America to our online offer for millions of Chinese learners, BBC Learning English provides multimedia English language teaching materials to meet learners' needs. Many of our materials are delivered as full length courses but each component of the course is standalone and can be studied on its own. This means the learner can choose the best way to study for them; by following a full course or by following the individual materials most appropriate to them. You can find out more about our current and future courses here. We also have a range of long-running features such as 6 Minute English, The English We Speak and Lingohack.

It has become almost impossible to imagine what our lives would be like without the many benefits of packaging - just think about the different packaging and single-use items you use on a daily basis. Yet as our global population grows in size and affluence, both our collective demand for packaging materials and the waste we generate as a result will increase dramatically. Currently, large amounts of packaging waste escape formal collection and recycling systems and eventually end up polluting the environment. Moreover, their material value is forever lost to the economy. The Ellen MacArthur Foundation estimates that uncollected plastic packaging waste alone is worth somewhere between 80 to 120 billion dollars a year. So how can we improve packaging systems in order to capture this wasted potential? Clearly, the way we currently design, recover, and reuse packaging urgently needs a rethink! In this course, you will learn about the design of sustainable packaging systems. To do so we will explore the design and business strategies of the circular economy. Contrary to our current industrial model, which extracts, uses and ultimately disposes of resources, a circular economy is regenerative by design. This means that products and services are reimagined from a systems perspective in order to minimize waste, maximize positive economic, environmental and social impacts, and keep resources locked in a cycle of restoration. This course is for you if you are interested in learning about sustainable packaging design. You'll also benefit if you are a professional in the packaging industry and want to learn how to find circular opportunities in your work. Students - particularly in design - will be able to broaden their knowledge of circular design and business strategies.
