1800s . 1830: Joseph Jackson Lister reduced spherical aberration (or the chromatic effect) by showing that several weak lenses used together at certain distances provided good magnification without blurring the image. This was the prototype for the compound microscope. 1872: Ernst Abbe, then research director of the Zeiss Optical Works, wrote a mathematical formula called the Abbe Sine. Three years later, in 1872, Abbe formulated his wave theory of microscopic imaging and defined what would become known as the Abbe Sine Condition. Several years later, Zeiss began to offer a lineup of 17 microscope objectives designed on the basis of Abbe's theoretical calculations. In his own words Abbe stated In 1830, the prototype for the Compound Microscope was created when Joseph Jackson Lister created a way to reduce spherical aberration, known as the chromatic effect, by combining multiple weak lenses without blurring the image, as opposed to lenses with higher magnifications. In 1872, the research director of the Zeiss Optical Works, Ernst. In 1872, Joseph Jackson showed that several weak lenses placed in a specific way gave a good magnification and this would eventually lead up to compound microscopes being developed

  3. The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century. Basic optical microscopes can be very simple, although many complex.

Appearing in Nachet catalogs between 1872 and 1892, this demonstration microscope was used to display specimens to a large audience. The microscope was photographed and described by Gerard Turner in his excellent volume Collecting Microscopes. A wooden handle attached to a round bar serves as the base and limb for the microscope ZEISS has been producing high-precision microscopes since the middle of the 19th century. From 1857 onwards, the simple models were followed by compound microscopes. Thanks to the work of scientist Ernst Abbe, microscopes have been based on theoretical calculations since 1872

1869-Zeiss and Abbe patent a device to illuminate objects under a microscope. 1872-Abbe's study of the limits on sharp imaging caused by the wave nature of light leads to his formulation of the Abbe sine condition. Abbe's theory of image formation becomes the basis for the design of high performance optics In response to criticism of his own works, Swinburne wrote essays, including Notes on Poems and Reviews (1866) and Under the Microscope (1872), which are celebrated for their wit and insight. Swinburne also published one novel, Love's Cross-Currents (1901), serially under a pseudonym, and left another, Lesbia Brandon , unfinished at his death 1907: The 100.000th microscope is presented to Nobel prize winner Robert Koch. 1881: Charles Darwin's son Horace founds the optical company Cambridge Instruments. 1876: Optical company C.

Ernst Abbe, physicist whose theoretical and technical innovations in optical theory led to great improvements in microscope design (such as the use of a condenser to provide strong, even illumination, introduced in 1870) and clearer understanding of magnification limits. In 1873 he discovered th Anton van Leeuwenhoek built a simple microscope with only one lens to examine blood, yeast, insects and many other tiny objects. Leeuwenhoek was the first person to describe bacteria, and he invented new methods for grinding and polishing microscope lenses that allowed for curvatures providing magnifications of up to 270 diameters, the best available lenses at that time After the invention of eyeglasses, the next progression of the microscope was in the 1500s when the first arrangement of two lenses was created to improve the magnification of an object. These were known as flea glasses and were used to examine creatures like the flea or other small objects. Jan 1, 1872. Ernst Abbe Ernst Abbe, then research.

Algernon Charles Swinburne (5 April 1837 - 10 April 1909) was an English poet, playwright, novelist, and critic. He wrote several novels and collections of poetry such as Poems and Ballads, and contributed to the famous Eleventh Edition of the Encyclopædia Britannica.. Swinburne wrote about many taboo topics, such as lesbianism, cannibalism, sado-masochism, and anti-theism Joseph Jackson Lister, (born January 11, 1786, London, England—died October 24, 1869, West Ham, Essex), English amateur opticist whose discoveries played an important role in perfecting the objective lens system of the microscope, elevating that instrument to the status of a serious scientific tool..

Microscopes are instruments designed to produce magnified visual or photographic images of small objects. The microscope must accomplish three tasks: produce a magnified image of the specimen, separate the details in the image, and render the details visible to the human eye or camera. This group of instruments includes not only multiple-lens. (1872 - 1970) Microscopes are renowned for their ability to allow the observer to see very small material objects more clearly. Through the years they have been supplemented with additional devices in order to enhance detail: Rheinberg filters, dark-ground and phase-contrast condensers to name just a few From 1872 onwards, all of Zeiss's microscope optics were based on calculations made by Abbe . In catalog 19, immersion systems were offered for the first time alongside new dry lens systems. Homogeneous oil immersion lenses followed in 1879 . Figure 6.

Until the advent of the 19 th century there had been autopsy reports of patients who may had suffered from infective endocarditis, but little was known of the disease and there had been no description of it. 1 By the beginning of the 20 th century, however, infective endocarditis had become a well described entity.

Abstract. England's flagship 'Improving Access to Psychological Therapies' (IAPT) service has cost around £1 billion yet Scott's (2018a) study suggests that only 9.2% of IAPT patients recover.

CONCLUSIONS: The use of the microscope was found to significantly increase the odds of longer operative time, but not influence rates of postoperative complications. Thus, without evidence from this study that the microscope decreases complications, the use of the microscope should be at the surgeon's discretion, validating the use of both.

Huntington's disease is a genetic disorder Aim: To investigate the effects of hepatitis B virus X (HBx) gene on apoptosis and cell cycle in hepatocyte line HL-7702 and to discuss the possible mechanisms in the pathway. Methods: The recombinant plasmid pcDNA3-X and vector pcDNA3 were transfected into HL-7702 cells and selected by G418 to construct two new cell lines, which were named HL-7702-HBx and HL-7702-con, respectively Ethanol can be produced from lignocellulosic biomass with the usage of ball milling pretreatment followed by enzymatic hydrolysis and fermentation. The sugar yields from lignocellulosic feed stocks are critical parameters for ethanol production process. The research results from this paper indicated that the yields of glucose and xylose were improved by adding any of the following dilute.
