what is an Encyclopedia ?

An Encyclopedia is a type of reference work – a compendium holding a summary of information from either all branches of knowledge or a particular branch of knowledge. Encyclopedias are divided into articles or entries, which are usually accessed alphabetically by article name. Encyclopedia entries are longer and more detailed than those in most dictionaries. Generally speaking, unlike dictionary entries, which focus on linguistic information about words, encyclopedia articles focus on factual information to cover the thing or concept for which the article name stands.

Encyclopedias have existed for around 2,000 years; the oldest still in existence, Naturalis Historia, was written in ca. AD 77 by Pliny the Elder. The modern encyclopedia evolved out of dictionaries around the 17th century. Historically, some encyclopedias were contained in one volume, but some, such as the Encyclopædia Britannica or the world's largest Enciclopedia universal ilustrada europeo-americana, became huge multi-volume works. Some modern encyclopedias, such as Wikipedia, are electronic and are often freely available.

The word encyclopedia comes from the Koine Greek γκύκλιος παιδεία, transliterated enkyklios paideia, meaning "general education" from enkyklios (γκύκλιος), meaning "circular, recurrent, required regularly, general" and paideia (παιδεία), meaning "education, rearing of a child"; it was reduced to a single word due to an error by copyists of Latin manuscripts. Together, the phrase literally translates as "complete instruction" or "complete knowledge".

Indeed, the purpose of an encyclopedia is to collect knowledge disseminated around the globe; to set forth its general system to the men with whom we live, and transmit it to those who will come after us, so that the work of preceding centuries will not become useless to the centuries to come; and so that our offspring, becoming better instructed, will at the same time become more virtuous and happy, and that we should not die without having rendered a service to the human race in the future years to come.

The World Renowned Environmental Scientist Dr. Priya Ranjan Trivedi dedicates the 24 Volume World Encyclopaedia of Nanoscience and Nanotechnology to the world citizenry

New Delhi, 31 December 2016

Dedicating the 24 Volume World Encyclopaedia of Nanoscience and Nanotechnology to the world citizenry on the eve of the New Year 2017, the world renowned environmental scientist and didactics Dr. Priya Ranjan Trivedi said that under the aegis of the World Institute of Nanotechnology (WIN), established as a CSR initiative of Computers (India) Limited, more researches will be conducted in the areas of nanoscience and nanotechnology and that the entire lifestyle and the manufacturing processes will be revamped by the effective use of small apparatus and equipment by using the art and science of nanotechnology.

The  Perpetual President of the World Institute of
Nanotechnology (WIN) Dr. P R Trivedi dedicating
the 24 Volume World Encyclopaedia of Nanoscience
and Nanotechnology at New Delhi on 31/12/2016.

Dr. Priya Ranjan Trivedi added that research based volumes in the specialized areas of (i) Nanotechnology Today; (ii) Emerging Areas of Nanotechnology; (iii) Applied Areas of Nanotechnology; (iv) Future of Nanotechnology; (v) Nanotechnology Concepts; (vi) Nanoparticles and Nanomaterials; (vii) Nanoelectronics and Nanomaterials; (viii) Nanotechnology Revolution; (ix) Nanomachanics and Nanomachines; (x) Recent Advances in Nanotechnology; (xi) Nanotechnology Information Resources; (xii) Health and Safety Applications of Nanotechnology; (xiii) Historical Developments in Nanotechnology; (xiv) Nanobiology and Nanomachines; (xv) Nanochemistry; (xvi) Nanophysics; (xvii) Nanoengineering; (xviii) Nanocomputers; (xix) Nanoelectronics; (xx) Nanobiotechnology; (xxi) Nanoeducation; (xxii) Nanolab; (xxiii) Nanoresearch; and (xxiv) Lexicon on Nanotechnology have been brought out for the benefit of scientists, researchers, policymakers, educators, professors and industry based professionals.

He invited the universities, colleges, institutions, ministries, departments and autonomous organizations to take benefit from this Encyclopaedia of 24 Volumes costing Rs. 58,500 only. He suggested that contact could be made through email on Email ID : nanotechnology@ecology.edu for placing orders and for receiving the Set of Encyclopaedia on a priority basis.

He predicted that different components produced with the help of nanoscience and nanotechnology will create a business of one trillion dollars and employment for at least two million young boys and girls in India.

Appreciating the researches in the areas of nanoscience and nanotechnology,
Dr. Trivedi further explained that a miracle will take place with nanotech benefitting the medical and health industry to the extent that the genetic disorders of a baby will be corrected before taking birth, the blind will be able to see everything, older persons will become younger, and that they will be able to live longer, the automobile and vehicles will be lighter and strong with greater efficiency, treatment of cancer will be possible through microscopic Robert.

Stressing the need for studies, teaching, training and applied researches in the specialized areas of nanoscience and nanotechnology, Dr. Trivedi said that there will be a revolution in the area of agriculture, farm management, pomology, food processing very soon with the introduction of nanotech based technologies to be transferred with a view to increasing productivity in the agriculture sector with a view to bringing the farmers above the poverty lines.

Advocating to strengthen the cause of Skill India, Make in India, Start Up India, Clean Up India and similar campaigns and announcements made by the Prime Minister Hon’ble Shri Narendra Modi and his Cabinet Colleagues for making the prosperous India, Dr. Trivedi said that the emerging appropriate techniques being developed in the areas of nanoscience will revolutionize the new and emerging area of rural and urban entrepreneurship. The problems relating to unemployment, peacelessness, pollution and population explosion will be reduced by creating alternative and sustainable jobs in India with the help of nanotechnology, Dr. Trivedi finally opined.
