Within months of the start of the First World War, Germany began to run out of the raw materials it needed to make explosives. As Germany faced imminent defeat, chemists such as Fritz Haber and Carl Bosch came to the rescue with Nobel Prize winning discoveries that overcame the shortages and enabled the country to continue in the war. Similarly, Britain could not have sustained its war effort for four years had it not been for chemists like Chaim Weizmann who was later to become the first president of the State of Israel. Michael Freemantle tells the stories of these and many other chemists and explains how their work underpinned and shaped what became known as The Chemists’ War. He reveals: • how chemistry contributed to the care of the sick and wounded and to the health and safety of troops; • how coal not only powered the war but was also an important source of the chemicals needed for the manufacture of explosives, dyes, medicines and antiseptics;• how Britain’s production of propellants relied on the slaughter of tens of thousands of whales;• how a precious metal played a critical role in the war;• how poisonous chemicals were used as weapons of mass destruction for the first time in the history of warfare and how chemists developed gas masks for protection against these weapons; • how the British naval blockade of Germany imperilled agricultural production in the United States. The book will appeal to the general reader as well as the many scientists and historians interested in the Great War.
The Stem Cell Epistles
Human embryos, it has been said, «have no muscles, nerves, digestive system, feet, hands, face, or brain; they have nothing to distinguish them as a human being, and if one of them died, no one would mourn as they would for one of us.» Consequently, early human embryos are being dismembered in laboratories around the world to produce embryonic stem cells, which, we are told, are the tools that will lead to the next quantum leap in medicine. Should Christians support such small sacrifices for something that might potentially relieve the suffering of millions, or should we vigorously oppose it?
Developmental biologist and professor of biochemistry Michael Buratovich was asked such a question (among others) by his students. This book contains his measured answers and provides support from the scientific literature to substantiate his claims. He shows that embryonic stem cells are unnecessary, since the renaissance in regenerative medicine is occurring largely without them. Furthermore, he sets forth the scientific and historic case that the embryo is the youngest and most vulnerable member of humanity, and that ones such as these are precisely those whom the Christian church worked to protect in the past–and should champion in the present.

Chemistry Lab Basics (Speedy Study Guides)
A study guide is an excellent foundation, especially when you are pursuing knowledge in science. Science is all about facts and provable information. In chemistry, you study a lot of compounds and combinations of information and without the building blocks, you've got nothing to work with. Getting help with those harder concepts and reminding yourself of the easy ones can save your life and make it easier to pass those classes or spark a passion.
Biochemistry Principles (Speedy Study Guides)
A strong understanding of the basic principles of biochemistry is an important resource for any student who aspires to a career in higher science. A well thought out and organized study guide helps students grasp and remember these principles by dividing the information into easily managed pieces and reinforcing basic but important scientific concepts.
Chemistry Basics (Speedy Study Guide)
A study guide of chemistry basics would give students bite sized chunks of information on a complex subject, making the task of learning it easier and more enjoyable. Study guides present detailed information on a topic in a compact and simplistic way, which helps the student grasp more of what they are being taught. Also, the visual aids that usually are found in study guides can be very effective in keeping the attention of the child as well as embedding the material in their memory.
