The
book of John Mastin works very thoroughly and takes up all the information
related to precious stones, be it for the practitioner or the enthusiast. This
manuscript works out the origin of gems in detail and lists their physical
properties-crystalline structure, color, hardness, and specific gravity. An
interesting add-on included in the book is the influence that magnetic and
electric fields will have on gemstones, explaining to the reader the particular
characteristic qualities of each gemstone. From this perspective, the cutting of
stones, imitations, and testing methods are analyzed. Whether for teaching
purposes or simple curiosity, this book is an informative guide for any
interested person in the allure of precious stones, as relevant for the general
public as it is in the jewelry world.
Lecture notes prepared
by Mr. M Praveen for the lectures meant to give engineering students based in
different fields of engineering foundational principles of chemistry. The key
topics that are covered in this course include electrochemistry, batteries,
corrosion control, and water technology, which cover the basic chemical aspects
of all these. This material deals with the chemistry of materials, fuels, and
combustion, giving the student background knowledge to apply chemical concepts
effectively. These notes will make studying easier for students, and with clear
explanations as well as practical applications, the feeling about how chemistry
plays into everyday engineering practices and innovations will grow even
bigger.
