Information:  - Chemistry is a branch of physical science that studies the composition, structure, properties and change of matter. Chemistry includes topics such as the properties of individual atoms, how atoms form chemical bonds to create chemical compounds, the interactions of substances through intermolecular forces that give matter its general properties, and the interactions between substances through chemical reactions to form different substances.  - Heinrich Emanuel Merck ( 15 September 1794 -- 14 February 1855 ) was an apothecary whose descendants are the founders of Merck and Company and Merck KGaA .  - Materia medica is a Latin medical term for the body of collected knowledge about the therapeutic properties of any substance used for healing (i.e., medicines). The term derives from the title of a work by the Ancient Greek physician Pedanius Dioscorides in the 1st century AD, "De materia medica", 'On Medical Material' (   in Greek). The term "materia medica" was used from the period of the Roman Empire until the 20th century, but has now been generally replaced in medical education contexts by the term "pharmacology".  - Pharmacists, also known as chemists (Commonwealth English) or druggists (North American and, archaically, Commonwealth English), are healthcare professionals who practice in pharmacy, the field of health sciences focusing on safe and effective medication use. A pharmacist is a member of the health care team directly involved with patient care. Pharmacists undergo university-level education to understand the biochemical mechanisms and actions of drugs, drug uses, therapeutic roles, side effects, potential drug interactions, and monitoring parameters. This is mated to anatomy, physiology, and pathophysiology. Pharmacists interpret and communicate this specialized knowledge to patients, physicians, and other health care providers.  - Apothecary is one term for a medical professional who formulates and dispenses "materia medica" to physicians, surgeons and patients. The modern pharmacist (also colloquially referred to as a chemist in British English) has taken over this role and in some languages and regions the word is still used to refer to a retail pharmacy or a pharmacist who owns one. The apothecaries' investigation of herbal and chemical ingredients was a precursor to the modern sciences of chemistry and pharmacology.  - British English is the English language as spoken and written in the United Kingdom or, more broadly, throughout the British Isles. Slight regional variations exist in formal, written English in the United Kingdom. For example, the adjective "wee" is almost exclusively used in parts of Scotland and Northern Ireland, and occasionally Yorkshire, whereas "little" is predominant elsewhere. Nevertheless, there is a meaningful degree of uniformity in "written" English within the United Kingdom, and this could be described by the term "British English". The forms of "spoken" English, however, vary considerably more than in most other areas of the world where English is spoken, so a uniform concept of British English is more difficult to apply to the spoken language. According to Tom McArthur in the "Oxford Guide to World English", British English shares "all the ambiguities and tensions in the word "British" and as a result can be used and interpreted in two ways, more broadly or more narrowly, within a range of blurring and ambiguity."  - A physician, medical practitioner, medical doctor or simply doctor is a professional who practises medicine, which is concerned with promoting, maintaining, or restoring health through the study, diagnosis, and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients and methods of treatmentknown as specialitiesor they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communitiesknown as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines (such as anatomy and physiology) underlying diseases and their treatmentthe "science" of medicineand also a decent competence in its applied practicethe art or "craft" of medicine.
