Problem: Given the question: Information: - Astronomy is a natural science that studies celestial objects and phenomena. It applies mathematics, physics, and chemistry, in an effort to explain the origin of those objects and phenomena and their evolution. Objects of interest include planets, moons, stars, galaxies, and comets; while the phenomena include supernovae explosions, gamma ray bursts, and cosmic microwave background radiation. More generally, all astronomical phenomena that originate outside Earth's atmosphere are within the purview of astronomy. A related but distinct subject, physical cosmology, is concerned with the study of the Universe as a whole. - The Maksutov (also called a "Mak") is a catadioptric telescope design that combines a spherical mirror with a weakly negative meniscus lens in a design that takes advantage of all the surfaces being nearly "spherically symmetrical". The negative lens is usually full diameter and placed at the entrance pupil of the telescope (commonly called a "corrector plate" or "meniscus corrector shell"). The design corrects the problems of off-axis aberrations such as coma found in reflecting telescopes while also correcting chromatic aberration. It was patented in 1941 by Russian optician Dmitri Dmitrievich Maksutov. Maksutov based his design on the idea behind the Schmidt camera of using the spherical errors of a negative lens to correct the opposite errors in a spherical primary mirror. The design is most commonly seen in a Cassegrain variation, with an integrated secondary, that can use all-spherical elements, thereby simplifying fabrication. Maksutov telescopes have been sold on the amateur market since the 1950s. - Amateur astronomy is a hobby whose participants enjoy watching the sky, and the abundance of objects found in it with the unaided eye, binoculars, or telescopes. Even though scientific research is not their main goal, many amateur astronomers make a contribution to astronomy by monitoring variable stars, tracking asteroids and discovering transient objects, such as comets and novae. - A reflecting telescope (also called a reflector) is an optical telescope which uses a single or combination of curved mirrors that reflect light and form an image. The reflecting telescope was invented in the 17th century as an alternative to the refracting telescope which, at that time, was a design that suffered from severe chromatic aberration. Although reflecting telescopes produce other types of optical aberrations, it is a design that allows for very large diameter objectives. Almost all of the major telescopes used in astronomy research are reflectors. Reflecting telescopes come in many design variations and may employ extra optical elements to improve image quality or place the image in a mechanically advantageous position. Since reflecting telescopes use mirrors, the design is sometimes referred to as a "catoptric" telescope. - John F. Gregory ( 1927 -- November 14 , 2009 ) was an American optical engineer and a popularizer of amateur telescope making . He is credited with the design of a version of the Maksutov telescope called the '' Gregory - Maksutov telescope '' . - Amateur telescope making is the activity of building telescopes as a hobby, as opposed to being a paid professional. Amateur telescope makers (sometimes called ATMs) build their instruments for personal enjoyment of a technical challenge, as a way to obtain an inexpensive or personally customized telescope, or as a research tool in the field of astronomy. Amateur telescope makers are usually a sub-group in the field of amateur astronomy. What is the relationship between 'john f. gregory' and 'optician'?

Please answer this: Information: - Sherlock Holmes is a fictional private detective created by British author Sir Arthur Conan Doyle. Known as a "consulting detective" in the stories, Holmes is known for a proficiency with observation, forensic science, and logical reasoning that borders on the fantastic, which he employs when investigating cases for a wide variety of clients, including Scotland Yard. - Scotland Yard (officially New Scotland Yard) is a metonym for the headquarters of the Metropolitan Police Service, the territorial police force responsible for policing most of London. - The Strand Magazine was a monthly magazine founded by George Newnes, composed of short fiction and general interest articles. It was published in the United Kingdom from January 1891 to March 1950, running to 711 issues, though the first issue was on sale well before Christmas 1890. Its immediate popularity is evidenced by an initial sale of nearly 300,000. Sales increased in the early months, before settling down to a circulation of almost 500,000 copies a month which lasted well into the 1930s. It was edited by Herbert Greenhough Smith from 1891 to 1930. The magazine's original offices were in Burleigh Street off The Strand, London. It was revived in 1998 as a quarterly magazine. - Sir George Newnes, 1st Baronet (13 March 1851 9 June 1910) was an English publisher and editor and a founding father of popular journalism. His company George Newnes Ltd continued publishing ground-breaking consumer magazines such as "Nova" long after his death. - A magazine is a publication, usually a periodical publication, which is printed or electronically published (sometimes referred to as an online magazine). Magazines are generally published on a regular schedule and contain a variety of content. They are generally financed by advertising, by a purchase price, by prepaid subscriptions, or a combination of the three.At its root, the word "magazine" refers to a collection or storage location. In the case of written publication, it is a collection of written articles. This explains why magazine publications share the word root with gunpowder magazines, artillery magazines, firearms magazines, and, in French, retail stores such as department stores. - Sir Arthur Ignatius Conan Doyle KStJ, DL (22 May 1859 7 July 1930) was a British writer and physician, most noted for creating the fictional detective Sherlock Holmes and writing stories about him which are generally considered milestones in the field of crime fiction. - Herbert Greenhough Smith ( 1855 -- 14 January 1935 ) was the first editor of The Strand Magazine which published many of Arthur Conan Doyle 's Sherlock Holmes stories . His active support and encouragement to Conan Doyle , and the magazine 's vigorous promotion of the Sherlock Holmes character , had much to do with the character 's success . - Crime fiction is the literary genre that fictionalises crimes, their detection, criminals, and their motives. It is usually distinguished from mainstream fiction and other genres such as historical fiction or science fiction, but the boundaries are indistinct. Crime fiction has multiple subgenres, including detective fiction (such as the whodunit), courtroom drama, hard-boiled fiction and legal thrillers. Suspense and mystery are key elements that are nearly ubiquitous to the genre. - Forensic science is the application of science to criminal and civil laws, mainlyon the criminal sideduring criminal investigation, as governed by the legal standards of admissible evidence and criminal procedure.
