Chemist
A chemist (from Greek ''chēm(ía)'' alchemy; replacing ''chymist'' from Medieval Latin ''alchemist'') is a scientist trained in the study of chemistry. Chemists study the composition of matter and its properties. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, chemical reaction rates, and other chemical properties. In Commonwealth English, pharmacists are often called chemists. Chemists use their knowledge to learn the composition and properties of unfamiliar substances, as well as to reproduce and synthesize large quantities of useful naturally occurring substances and create new artificial substances and useful processes. Chemists may specialize in any number of subdisciplines of chemistry. Materials scientists and metallurgists share much of the same education and skills with chemists. The work of chemists is often related to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Society Of Chemistry
The Royal Society of Chemistry (RSC) is a learned society (professional association) in the United Kingdom with the goal of "advancing the chemistry, chemical sciences". It was formed in 1980 from the amalgamation of the Chemical Society, the Royal Institute of Chemistry, the Faraday Society, and the Society for Analytical Chemistry with a new Royal Charter and the dual role of learned society and professional body. At its inception, the Society had a combined membership of 34,000 in the UK and a further 8,000 abroad. The headquarters of the Society are at Burlington House, Piccadilly, London. It also has offices in Thomas Graham House in Cambridge (named after Thomas Graham (chemist), Thomas Graham, the first president of the Chemical Society) where ''RSC Publishing'' is based. The Society has offices in the United States, on the campuses of The University of Pennsylvania and Drexel University, at the University City Science Center in Philadelphia, Pennsylvania, in both Beijing a ...

2003 Deaths
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

Macular Society
The Macular Society is a UK charity that offers support to anyone affected by central vision loss. Many of the charity's members have age-related macular degeneration (AMD), but its services are open to people with various retinal conditions, including myopic macular degeneration, diabetic retinopathy, and inherited retinal dystrophies like Stargardt disease, Best disease, and Sorsby fundus dystrophy. The society coordinates activities across the UK from its headquarters in Andover, Hampshire. Its primary goal is to combat macular disease by funding research, providing a range of support services, and raising awareness of eye health. Services To combat isolation, loneliness and mental ill-health among people with sight loss, the society provides several free services. These include: * More than 400 local support groups * Advice and Information Service * Telephone counselling * Skills training to help people remain independent * Patient information in large-print, audio ...

British Stammering Association
The British Stammering Association (BSA), trading as STAMMA since 2019, is a national membership organisation in the United Kingdom for adults and children who stammer, their friends and families, speech and language therapists and other professionals. It became a charity in 1978 and is based in London. The mission of the charity is to support anyone who stammers in the UK and tackle the stigma, ignorance and discrimination that people who stammer face so that they can live their lives in full and with dignity. It describes stammering as a neurological condition and estimates that up to 3% of adults in the UK have a stammer. Organisation The association's chief executive, since June 2018, is Jane Powell. The chair, since 2021, is Joanna Gaukroger. President and patrons The organisation's president was Brian Dodsworth, who died in 2021.

Stammering
Stuttering, also known as stammering, is a speech disorder in which the flow of speech is disrupted by involuntary repetitions and prolongations of sounds, syllables, words, or phrases as well as involuntary silent pauses or blocks in which the person who stutters is unable to produce sounds. The term ''stuttering'' is most commonly associated with involuntary sound repetition, but it also encompasses the abnormal hesitation or pausing before speech, referred to by people who stutter as ''blocks'', and the prolongation of certain sounds, usually vowels or semivowels. According to Watkins et al., stuttering is a disorder of "selection, initiation, and execution of motor sequences necessary for fluent speech production". arlson, N. (2013). Human Communication. In Physiology of behavior (11th ed., pp. 497–500). Boston: Allyn and Bacon./ref> For many people who stutter, repetition is the main concern. The term "stuttering" covers a wide range of severity, from barely perceptible im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Laboratory Safety
Many laboratories contain significant risks, and the prevention of laboratory accidents requires great care and constant vigilance. Examples of risk factors include high voltages, high and low pressures and temperatures, corrosive and toxic chemicals and chemical vapours, radiation, fire, explosions, and biohazards including infective organisms and their toxins. Measures to protect against laboratory accidents include safety training and enforcement of laboratory safety policies, safety review of experimental designs, the use of personal protective equipment, and the use of the buddy system for particularly risky operations. In many countries, laboratory work is subject by health and safety legislation. In some cases, laboratory activities can also present environmental health risks, for example, the accidental or deliberate discharge of toxic or infective material from the laboratory into the environment. Chemical hazards Hazardous chemicals present physical and/or health thre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Magnum Opus
A masterpiece, ''magnum opus'' (), or ''chef-d’œuvre'' (; ; ) in modern use is a creation that has been given much critical praise, especially one that is considered the greatest work of a person's career or a work of outstanding creativity, skill, profundity, or workmanship. Historically, a "masterpiece" was a work of a very high standard produced to obtain membership of a guild or academy in various areas of the visual arts and crafts. Etymology The form ''masterstik'' is recorded in English or Scots in a set of Aberdeen guild regulations dated to 1579, whereas "masterpiece" is first found in 1605, already outside a guild context, in a Ben Jonson play. "Masterprize" was another early variant in English. In English, the term rapidly became used in a variety of contexts for an exceptionally good piece of creative work, and was "in early use, often applied to man as the 'masterpiece' of God or Nature". History Originally, the term ''masterpiece'' referred to a piece of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
