Question 1 Microscopy Is the Technical Field of Using Microscopes to View Objects and Areas of Objects That Cannot Be Seen with Seen with the Naked Eye
Question 1 Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with seen with the naked eye. Microscopy dates back to the 17th- century. In the first century A.D Seneca described actual magnification by a globe of water. The first modern application of optics occurred in Florence around 1280 A.D with the use of glasses as an aid to vision. The early history of the microscope and its inventors is shrouded in much confusion. Credit for the first compound microscope is given to Hans Jansen or his son Zacharias around 1595. The description of Jansen’s microscope was preserved until the early 1600’s. The instrument consisted of three sliding tubes measuring 18 inches in length when fully extended and two inches in diameter. The microscope was said to have a magnification of 3 x when closed and 9 x when fully extended. In the 18th century many mechanical improvements were made in the microscope but images had colourful haloes and were blurry. As the lenses multiplied, so did the distortions. The best simple microscopes attain about two micron resolutions but the best compound resolutions only had five micron resolution. The colour haloes are due to chromatic aberration. This is when light is transmitted through a substance and it will be bent different amounts depending upon its wavelength. This means that a lens will have a different focus for different colours of light. The solution to this problem came not from microscopes but telescopes in the 1730’s. -

Lecture 30 Origins of Horticultural Science
Lecture 30 1 Lecture 30 Origins of Horticultural Science The origin of horticultural science derives from a confl uence of 3 events: the formation of scientifi c societies in the 17th century, the creation of agricultural and horticultural societies in the 18th century, and the establishment of state-supported agricultural research in the 19th century. Two seminal horticultural societies were involved: The Horticultural Society of London (later the Royal Horticulture Society) founded in 1804 and the Society for Horticultural Science (later the American Society for Horticultural Science) founded in 1903. Three horticulturists can be considered as the Fathers of Horticultural Science: Thomas Andrew Knight, John Lindley, and Liberty Hyde Bailey. Philip Miller (1691–1771) Miller was Gardener to the Worshipful Company of Apothecaries at their Botanic Garden in Chelsea and is known as the most important garden writer of the 18th century. The Gardener’s and Florist’s Diction- ary or a Complete System of Horticulture (1724) was followed by a greatly improved edition entitled, The Gardener’s Dictionary containing the Methods of Cultivating and Improving the Kitchen, Fruit and Flower Garden (1731). This book was translated into Dutch, French, German and became a standard reference for a century in both England and America. In the 7th edition (1759), he adopted the Linnaean system of classifi cation. The edition enlarged by Thomas Martyn (1735–1825), Professor of Botany at Cambridge University, has been considered the largest gardening manual to have ever existed. Miller is credited with introducing about 200 American plants. The 16th edition of one of his books, The Gardeners Kalendar (1775)—reprinted in facsimile edition in 1971 by the National Council of State Garden Clubs—gives direc- tions for gardeners month by month and contains an introduction to the science of botany. -

To Take Into Consideration the Propriety Of
his was the subject for discussion amongst the seventeen microscopists who met at Edwin Quekett’s house No 50 Wellclose Square, in the Borough of Stepney, East London on 3rd September 1839. It was resolved that such a society be formed Tand a provisional committee be appointed to carry this resolution into effect. The appointed provisional committee of seven were to be responsible for the formation of our society, they held meetings at their homes and drew up a set of rules. They adopted the name ‘Microscopical Society of London’ and arranged a public meeting on the 20th December 1839 at the rooms of the Horticultural Society, 21 Regent Street. Where a Nathaniel Bagshaw Ward © National Portrait Gallery, London President, Treasurer and Secretary were elected, the provisional committee also selected the size of almost airtight containers. Together with George 3 x 1 inch as a standard for glass slides.

His glass plant cases allowed the growth of orchids and ferns in the Victorian home and in 1842 he wrote a book on the subject. However glass was subject to a tax making cases expensive so Ward lobbied successfully for its repeal in 1845. -
The Development of Horticultural Science in England, 1910-1930
The Development of Horticultural Science in England, 1910-1930 Paul Smith Department of Science and Technology Studies University College London Thesis submitted for the Degree of Doctor of Philosophy July 2016 I, Paul Smith, confirm the work presented in this thesis is my own. Where information has been derived from other sources, I confirm it has been indicated in the thesis. 2 Abstract This thesis explores how horticultural science was shaped in England in the period 1910-1930. Horticultural science research in the early twentieth century exhibited marked diversity and horticulture included bees, chickens, pigeons,pigs, goats, rabbits and hares besides plants. Horticultural science was characterised by various tensions arising from efforts to demarcate it from agriculture and by internecine disputes between government organisations such as the Board of Agriculture, the Board of Education and the Development Commission for control of the innovative state system of horticultural research and education that developed after 1909. Both fundamental and applied science research played an important role in this development. This thesis discusses the promotion of horticultural science in the nineteenth century by private institutions, societies and scientists and after 1890 by the government, in order to provide reference points for comparisons with early twentieth century horticultural science. Efforts made by the new Horticultural Department of the Board of Agriculture and by scientists and commercial growers raised the academic status of -
The Shropshire Enlightenment: a Regional Study of Intellectual Activity in the Late Eighteenth and Early Nineteenth Centuries
The Shropshire Enlightenment: a regional study of intellectual activity in the late eighteenth and early nineteenth centuries by Roger Neil Bruton A thesis submitted to the University of Birmingham for the degree of Doctor of Philosophy School of History and Cultures College of Arts and Law University of Birmingham January 2015 University of Birmingham Research Archive e-theses repository This unpublished thesis/dissertation is copyright of the author and/or third parties. The intellectual property rights of the author or third parties in respect of this work are as defined by The Copyright Designs and Patents Act 1988 or as modified by any successor legislation. Any use made of information contained in this thesis/dissertation must be in accordance with that legislation and must be properly acknowledged. Further distribution or reproduction in any format is prohibited without the permission of the copyright holder. Abstract The focus of this study is centred upon intellectual activity in the period from 1750 to c1840 in Shropshire, an area that for a time was synonymous with change and innovation. It examines the importance of personal development and the influence of intellectual communities and networks in the acquisition and dissemination of knowledge. It adds to understanding of how individuals and communities reflected Enlightenment aspirations or carried the mantle of ‘improvement’ and thereby contributes to the debate on the establishment of regional Enlightenment. The acquisition of philosophical knowledge merged into the cultural ethos of the period and its utilitarian characteristics were to influence the onset of Industrial Revolution but Shropshire was essentially a rural location. The thesis examines how those progressive tendencies manifested themselves in that local setting. -

Then in 1813, Louis Jacques Thénard of École Polytechnique in Paris discovered the decomposi- tion of ammonia to nitrogen and hydrogen over “red-hot metals” and recognized that the phenomenon was due to some catalytic reaction [1, 2]. The concept was followed up by Humphry Davy and Michael Faraday at the Royal Institution of London who, in 1817, reported the flameless catalytic combustion of coal gas and air over heated platinum wire producing bright white ignition. Their results were reproducible when using palladium, but not on copper, silver, iron, gold, and zinc [1, 3]. These experiments made clear that there was some form of cat- alytic role associated with the different metals. The discovery soon became the basisfortheinventionofthecoalminesafetylamp,alsoknownastheDavy lamp – although mysteriously but rather practically, the use of inefficient steel iron rather than platinum gauze became the standard for Davy lamps.
