This engineer who studied optometry had a stint as a jeweler, later despite hard times changed the way bread loaves were sold!!!

Otto Frederick Rohwedder (July 7, 1880 – November 8, 1960) was an American inventor and engineer who created the first automatic bread-slicing machine for commercial use. It was first used by the Chillicothe Baking Company in Chillicothe, Missouri in 1928. Rohwedder was born in Des Moines, Iowa in 1880, the son of Claus and Elizabeth Rohwedder, of ethnic German descent. When a child, Rohwedder and his family moved to Davenport, where he lived until the age of 21. He attended Davenport public schools. Then he became an apprentice to a jeweler to learn a trade. Rohwedder also studied optometry, graduating in 1900 with a degree in optics from what is now the Northern Illinois College of Ophthalmology and Otology in Chicago. He became a jeweler.

Rohwedder first had a brief career as a jeweler, and became the owner of three jewelry stores in St. Joseph. His used his work with watches and jewelry to create inventions of new machines. Convinced he could develop a bread slicing machine, he sold his jewelry stores to fund the development effort and manufacture the machines. In 1917 a fire broke out at the factory where Rohwedder was manufacturing his machine. It destroyed his prototype and blueprints. With the need to get funding again, Rohwedder was delayed for several years in bringing the bread slicer to market.

In 1927 Rohwedder successfully designed a machine that not only sliced the bread but wrapped it. He applied for patents to protect his invention and sold the first machine to a friend and baker Frank Bench, who installed it at the Chillicothe Baking Company, in Chillicothe, Missouri in 1928. The first loaf of sliced bread was sold commercially on July 7, 1928. Sales of the machine to other bakeries increased and sliced bread became available across the country. Rohwedder had seven patents approved from 1927-1936 having to do with bread slicing and handling. His original bread slicing machine is in the Smithsonian Institution in Washington, DC.

Gustav Papendick, a baker in St. Louis, Missouri, bought Rohwedder's second machine and found he could improve on it. He developed a better way to have the machine wrap and keep bread fresh. He also applied for patents for his concepts. In 1930 Continental Baking Company introduced Wonder Bread as a sliced bread. It was followed by other major companies when they saw how the bread was received. By 1932 the availability of standardized slices had boosted sales of automatic, pop-up toasters, an invention of 1926 by Charles Strite. In 1933 American bakeries for the first time produced more sliced than unsliced bread loaves.

That same year Rohwedder sold his patent rights to the Micro-Westco Co. of Bettendorf, Iowa and joined the company. He became vice-president and sales manager of the Rohwedder Bakery Machine Division. In 1951 Rohwedder at age 71 retired from Micro-Westco Co. and moved with his wife Carrie to Albion, Michigan, where their daughter Margaret (Rohwedder) Steinhauer and his sister Elizabeth Pickerill lived. Rohwedder died in Concord, Michigan on November 8, 1960. He was buried at Riverside Cemetery in Albion.

Sliced bread is a loaf of bread that has been pre-sliced with a machine and packaged for convenience. It was first sold in 1928, advertised as "the greatest forward step in the baking industry since bread was wrapped". This led to the popular phrase, "the greatest thing since sliced bread".

This Orientalist reconstructed the political history of deccan, history of viashnavism and other sects and pledge social reforms

Ramakrishna Gopal Bhandarkar (July 6, 1837 – August 24, 1925) was an Indian scholar, orientalist, and social reformer. Bhandarkar was born in Malvan in Ratnagiri district of Maharashtra. After his early schooling in Ratnagiri, he studied at Elphinstone College in Bombay. Along with Mahadev Govind Ranade, Bhandarkar was among the first graduates in 1862 from Bombay University. He obtained his Master’s degree the following year, and was awarded a Ph.D. from University of Göttingen in 1885.

Bhandarkar taught at Elphinstone College and Deccan College during his distinguished teaching career. He was involved in research and writing throughout his life. He retired in 1894 as the Vice Chancellor of Bombay University. Historian R. S. Sharma wrote of him: "He reconstructed the political history of the Deccan of the Satavahanas and the history of Vaishnavism and other sects. A great social reformer, through his researches he advocated widow marriages and castigated the evils of the caste system and child marriage." As an educationist, he was elected to the Council of India in 1903 as a non-official member. Gopal Krishna Gokhale was another member to the Council. In 1911 Ramakrishna Gopal Bhandarkar was knighted C.I.E.(Companion) and became "Sir" literally!

Professor Bhandarkar was very well known figure in European Academic world and the British government sent him as its delegate to congress of Orientalists held at Vienna in 1886. His scholarly paper on Sanskrit manuscripts was highly appreciated by German scholars. Germany was leading in Indology in those days. Gottingen University conferred honorary Ph.D. and Bombay University a L.L.D on him.

In 1853, while a student, Bhandarkar became a member of the Paramhansa Sabha, an association for furthering liberal ideas which was then secret to avoid the wrath of the powerful and orthodox elements of contemporary society. Visits from Keshub Chunder Sen during 1864 had inspired the members of the Sabha. 

In 1866, some of the members held a meeting at the home of Atmaram Pandurang and publicly pledged to certain reforms, including (1) denunciation of the caste system, (2) encouragement of widow remarriage, (3) encouragement of female education, and (4) abolition of child marriage.

The members concluded that religious reforms were required as a basis for social reforms. They held their first prayer meeting on 31 March 1867, which eventually led to the formation of the Prarthana Samaj. Another visit by Keshub Chunder Sen and visits of Protap Chunder Mozoomdar and Navina Chandra Rai, founder of Punjab Brahmo Samaj, boosted their efforts.

The world-renowned Bhandarkar Oriental Research Institute in Pune is named after Ramakrishna Gopal Bhandarkar.

This world's most famous SHEEP took the science a step further!!!

Dolly (5 July 1996 – 14 February 2003) was a female domestic sheep, and the first mammal to be cloned from an adult somatic cell, using the process of nuclear transfer. She was cloned by Ian Wilmut, Keith Campbell and colleagues at the Roslin Institute, part of the University of Edinburgh, and the biotechnology company PPL Therapeutics near Edinburgh in Scotland, the United Kingdom. The funding for Dolly's cloning was provided by PPL Therapeutics and the Ministry of Agriculture. She has been called "the world's most famous sheep" by sources including BBC News and Scientific American.

The cell used as the donor for the cloning of Dolly was taken from a mammary gland, and the production of a healthy clone therefore proved that a cell taken from a specific part of the body could recreate a whole individual. On Dolly's name, Wilmut stated "Dolly is derived from a mammary gland cell and we couldn't think of a more impressive pair of glands than Dolly Parton's".

Dolly was born on 5 July 1996 and had three mothers (one provided the egg, another the DNA and a third carried the cloned embryo to term). She was created using the technique of somatic cell nuclear transfer, where the cell nucleus from an adult cell is transferred into an unfertilised oocyte (developing egg cell) that has had its cell nucleus removed. The hybrid cell is then stimulated to divide by an electric shock, and when it develops into a blastocyst it is implanted in a surrogate mother. 

Dolly was the first clone produced from a cell taken from an adult mammal. The production of Dolly showed that genes in the nucleus of such a maturedifferentiated somatic cell are still capable of reverting to an embryonic totipotent state, creating a cell that can then go on to develop into any part of an animal. Dolly's existence was announced to the public on 22 February 1997.

Dolly lived her entire life at the Roslin Institute in Edinburgh. There she was bred with a Welsh Mountain ram and produced six lambs in total. Her first lamb, named Bonnie, was born in April 1998. The next year Dolly produced twin lambs Sally and Rosie, and she gave birth to triplets Lucy, Darcy and Cotton in the year after that. In late 2001, at the age of four, Dolly developed arthritis and began to walk stiffly. This was treated with anti-inflammatory drugs.

On 14 February 2003, Dolly was euthanised because she had a progressive lung disease and severe arthritis. A Finn Dorset such as Dolly has a life expectancy of around 11 to 12 years, but Dolly lived to be only a month over 6.5 years of age. Roslin scientists stated that they did not think there was a connection with Dolly being a clone, and that other sheep in the same flock had died of the same disease. Such lung diseases are a particular danger for sheep kept indoors, and Dolly had to sleep inside for security reasons.

In biology, cloning is the process of producing similar populations of genetically identical individuals that occurs in nature when organisms such as bacteria, insects or plants reproduce asexually. Cloning in biotechnology refers to processes used to create copies of DNA fragments (molecular cloning), cells (cell cloning), or organisms. 

The term clone is derived from the Ancient Greek word κλών klōn, "twig", referring to the process whereby a new plant can be created from a twig. In horticulture, the spelling clon was used until the twentieth century; the final e came into use to indicate the vowel is a "long o" instead of a "short o". Since the term entered the popular lexicon in a more general context, the spelling clone has been used exclusively.

The Highest point above the sea level in the world is named after HIM!!!

Colonel Sir George Everest (July 4, 1790 — December 1, 1866) was a Welsh surveyor and geographer, and the Surveyor General of India from 1830 through 1843. Everest was largely responsible for completing the section of the Great Trigonometric Survey of India along the meridian arc from southern India extending north to Nepal, a distance of about 2,400 kilometres (1,500 mi). This survey was started by William Lambtonin 1806 and it lasted for several decades. In 1865, Mount Everest was named in his honour despite his objections by the Royal Geographical Society. This enormous peak was surveyed by Everest's successor, Andrew Scott Waugh, in his role as the Surveyor-General of India.

Everest was born in Gwernvale Manor, just west of Crickhowell in Powys, Wales, in 1790, and he was baptised in Greenwich. Commissioned into the Royal Artillery, in 1818, Lt. Everest was appointed as assistant to Colonel William Lambton, who had started the Great Trigonometrical Survey of the subcontinent in 1806. On Lambton's death in 1823, Everest succeeded to the post of superintendent of the survey, and in 1830 he was appointed as the Surveyor-General of India.

Everest retired in 1843 and he returned to live in the United Kingdom, where he became a Fellow of the Royal Society. He was dubbed a knight in 1861, and in 1862 he was elected as the vice-president of the Royal Geographical Society. Everest died in London in 1866 and is buried in St Andrew's Church, Hove, near Brighton. His niece, Mary Everest, married mathematician George Boole.

He owned a house in Mussoorie, Uttarakhand, India, for some years. Although almost derelict, it still has its roof, and there are plans to make it into a museum at some point in time. Sir George Everest's House and Laboratory, also known as the Park Estate, is situated about 6 kilometres (4 mi) from Gandhi Chowk / Library Bazaar, (West end of the Mall Road, in Mussoorie). Built in 1832 it was the home and laboratory of Sir George Everest. The house is situated in a place from where one can catch the panoramic view of Doon Valley on one side and a panoramic view of the Aglar Rivervalley and the snowbound Himalayan ranges on the other.

Mount Everest (also known in Nepal as Sagarmatha and in Tibet as Qomolangma) is the Earth's highest mountain. It is located in the Mahalangur section of the Himalayas. Its peak is 8,848 metres (29,029 ft) above sea level and is the 5th furthest point from the center of the Earth. The international border between China and Nepal runs across the precise summit point. Its massif includes neighboring peaks Lhotse, 8,516 m (27,940 ft); Nuptse, 7,855 m (25,771 ft) and Changtse, 7,580 m (24,870 ft).

In 1856, the Great Trigonometric Survey of India established the first published height of Everest, then known as Peak XV, at 29,002 ft (8,840 m). The current official height of 8,848 m (29,029 ft) as recognized by Nepal and China was established by a 1955 Indian survey and subsequently confirmed by a Chinese survey in 1975. In 1865, Everest was given its official English name by the Royal Geographical Society upon a recommendation by Andrew Waugh, the British Surveyor General of India. Waugh named the mountain after his predecessor in the post, Sir George Everest. Although Tibetans had called Everest "Chomolungma" for centuries, Waugh was unaware of this because Tibet and Nepal were closed to foreigners at the time thus preventing any attempts to obtain local names.

The first recorded efforts to reach Everest's summit were made by British mountaineers. With Nepal not allowing foreigners into the country at the time, the British made several attempts on the north ridge route from the Tibetan side. After the first reconnaissance expedition by the British in 1921 reached 7,000 m (22,970 ft) on the North Col, the 1922 expedition pushed the North ridge route up to 8,320 m (27,300 ft) marking the first time a human had climbed above 8,000 m (26,247 ft). Tragedy struck on the descent from the North col when seven porters were killed in an avalanche. 

The 1924 expedition resulted in the greatest mystery on Everest to this day: George Mallory and Andrew Irvine made a final summit attempt on June 8 but never returned, sparking debate as to whether they were the first to reach the top. They had been spotted high on the mountain that day but disappeared in the clouds, never to be seen again until Mallory's body was found in 1999 at 8,155 m (26,755 ft) on the North face. Tenzing Norgay and Edmund Hillary made the first official ascent of Everest in 1953 using the southeast ridge route. Tenzing had reached 8,595 m (28,199 ft) the previous year as a member of the 1952 Swiss expedition.

This self-taught mathematician taught in coffee houses for free, yet made his mark with the LIFE OF HIS PI !!!!

William Jones, (1675 – 3 July 1749) was a Welsh mathematician, most noted for his proposal for the use of the symbol π (the Greek letter pi) to represent the ratio of the circumference of a circle to its diameter. He was a close friend of Sir Isaac Newton and SirEdmund Halley. In November, 1711 he became a Fellow of the Royal Society, and was later its Vice-President.

William Jones was born the son of Siôn Siôr (John George Jones) and Elizabeth Rowland in the parish of Llanfihangel Tre'r Beirdd, about 4 miles west of Benllech on the Isle of Anglesey. He attended a charity school at Llanfechell, also on the Isle of Anglesey, where his mathematical talents were spotted by the local landowner who arranged for him to be given a job in London working in a merchant's counting-house. He owed his successful career partly to the patronage of the distinguished Bulkeley family of northWales, and later to the Earl of Macclesfield.

Jones initially served at sea, teaching mathematics on board Navy ships between 1695 and 1702, where he became very interested in navigation and published A New Compendium of the Whole Art of Navigation in 1702, dedicated to a benefactor John Harris. In this work he applied mathematics to navigation, studying methods of calculating position at sea. After his voyages were over he became a mathematics teacher in London, both in coffee houses and as a private tutor to the son of the future Earl of Macclesfield and also the future Baron Hardwicke. He also held a number of undemanding posts in government offices with the help of his former pupils.

Jones published Synopsis Palmariorum Matheseos in 1706, a work which was intended for beginners and which included theorems on differential calculus and infinite series. This used π as an abbreviation for perimeter. His 1711 work Analysis per quantitatum series, fluxiones ac differentias introduced the dot notation for differentiation in calculus. In 1731 he published Discourses of the Natural Philosophy of the Elements.

Before being ascribed a modern name, pi existed under the guise of a bulkier, more antiquated phrase: quantitas in quam cum multiflicetur diameter, proveniet circumferencia—Latin for “the quantity which, when the diameter is multiplied by it, yields the circumference.” While descriptive, the collection of words required to denote pi before “pi” did not lend itself to clear or efficient discussion of the concept. Prior to Jones publishing his bold decision, fractions like 22/7 or 355/113 often served to fill in for the mysterious constant, but gave the erroneous impression that the number was a rational one, which can be fully expressed by one whole number divided into another—an assumption that had not yet been disproved, but with which Jones firmly disagreed. For this reason, only an idealized symbol would suffice to represent the concept, and so the Welshman turned to the Greek alphabet.

π, written in Roman letters as “pi,” is the Greek equivalent to our letter ‘p’. For this reason, 17th-century mathematician William Oughtred used π to denote the “periphery,” or the circumference of any given circle—a value that changed as the circle changed. Jones borrowed this earlier logic and applied it to his theory of an irrational, but universal constant value for the circle’s circumference-to-diameter ratio. Johann Lambert’s definitive proof in 1761 that π was an irrational number justified Jones’s earlier instinct, and once Swiss mathematician Leonhard Euler began to use and widely disseminate the symbol π in correspondence with his contemporaries, π was here to stay.

He married twice, firstly the widow of his counting-house employer, whose property he inherited on her death, and secondly, in 1731, Mary, the 22-year-old daughter of cabinet-maker George Nix, with whom he had two surviving children. His son, also named William Jones and born in 1746, was a renowned philologist who first recognised the existence of the Indo-European language group.

The symbol π had been used in the previous century in a significantly different way by the rector and mathematician, William Oughtred (c. 1575-1 660), in his book Clavis Mathematicae (first published in 1631). Oughtred used π to represent the circumference of a given circle, so that his π varied according to the circle's diameter, rather than representing the constant we know today. The circumference of a circle was known in those days as the 'periphery', hence the Greek equivalent 'π' of our letter 'π'. Jones's use of π was an important philosophical step which Oughtred had failed to make even though he had introduced other mathematical symbols, such as :: for proportion and 'x' as the symbol for multiplication.

On Oughtred's death in 1660 some books and papers from his fine mathematical library were acquired by the mathematician John Collins (1625-83), from whom they would eventually pass to Jones. The irrationality of π was not proved until 1761 by Johann Lambert (172877), then in 1882 Ferdinand Lindemann (1852-1939) proved that π was a nonalgebraic irrational number, a transcendental number (one which is not a solution of an algebraic equation, of any degree, with rational coefficients). The discovery that there are two types of irrational numbers, however, does not detract from Jones's achievement in recognising that the ratio of the circumference to the diameter could not be expressed as a rational number.

Beyond his first use of the symbol p Jones is of interest because of his connection to a number of key mathematicial, scientific and political characters of the 18th century. He was also responsible for developing one of the greatest scientific libraries and mathematical archives in the country which remained in the hands of the Macclesfield family, his patrons, for nearly 300 years.

SOS....SOS...SOS was implemented today in 1908!!!

SOS is the commonly used description for the international Morse code distress signal (· · · – – – · · ·). This distress signal was first adopted by the German government in radio regulations effective April 1, 1905, and became the worldwide standard under the second International Radiotelegraphic Convention, which was signed on November 3, 1906 and became effective on July 1, 1908. SOS remained the maritime radio distress signal until 1999, when it was replaced by the Global Maritime Distress Safety System. SOS is still recognized as a visual distress signal.

The SOS distress signal is a continuous sequence of three dits, three dahs, and three dits, all run together without letter spacing. In International Morse Code, three dits form the letter S, and three dahs make the letter O, so "SOS" became an easy way to remember the order of the dits and dahs. In modern terminology, SOS is a Morse "procedural signal" or "prosign", and the formal way to write it is with a bar above the letters: SOS.

In popular usage, SOS became associated with such phrases as "save our ship", "save our souls" and "send out succour". These may be regarded as mnemonics, but SOS does not actually stand for anything and is not an abbreviation, acronym or initialism. In fact, SOS is only one of several ways that the combination could have been written; VTB, for example, would produce exactly the same sound, but SOS was chosen to describe this combination. SOS is the only 9-element signal in Morse code, making it more easily recognizable, as no other symbol uses more than 8 elements.

A distress signal is an internationally recognized means for obtaining help. Distress signals take the form of or are commonly made by using radio signals, displaying a visually detected item or illumination, or making an audible sound, from a distance. A distress signal indicates that a person or group of people, ship, aircraft, or other vehicle is threatened by grave and imminent danger and requests immediate assistance. Use of distress signals in other circumstances may be against local or international law.

In order for distress signalling to be the most effective, two parameters must be communicated:

• Alert or notification of a distress in progress
• Position or location (or localization or pinpointing) of the party in distress.

For example, a single aerial flare alerts observers to the existence of a vessel in distress somewhere in the general direction of the flare sighting on the horizon but extinguishes within one minute or less. A hand held flare burns for 3 minutes and can be used to localize or pinpoint more precisely the exact location or position of the party in trouble. An EPIRB both notifies or alerts authorities and at the same time provides position indication information.
