173. O. Henry

O. Henry, pseudonym of William Sydney Porter, original name William Sidney Porter (born Sept. 11, 1862, Greensboro, N.C., U.S. - died June 5, 1910, New York, N.Y.), American short-story writer whose tales romanticized the commonplace - in particular the life of ordinary people in New York City. His stories expressed the effect of coincidence on character through humour, grim or ironic, and often had surprise endings, a device that became identified with his name and cost him critical favour when its vogue had passed.

Porter attended a school taught by his aunt, then clerked in his uncle’s drugstore. In 1882 he went to Texas, where he worked on a ranch, in a general land office, and later as teller in the First National Bank in Austin. He began writing sketches at about the time of his marriage to Athol Estes in 1887, and in 1894 he started a humorous weekly, The Rolling Stone. When that venture failed, Porter joined the Houston Post as reporter, columnist, and occasional cartoonist.

In February 1896 he was indicted for embezzlement of bank funds. Friends aided his flight to Honduras. News of his wife’s fatal illness, however, took him back to Austin, and lenient authorities did not press his case until after her death. When convicted, Porter received the lightest sentence possible, and in 1898 he entered the penitentiary at Columbus, Ohio; his sentence was shortened to three years and three months for good behaviour. As night druggist in the prison hospital, he could write to earn money for support of his daughter Margaret. His stories of adventure in the southwest U.S. and Central America were immediately popular with magazine readers, and when he emerged from prison W.S. Porter had become O. Henry.

In 1902 O. Henry arrived in New York - his “Bagdad on the Subway.” From December 1903 to January 1906 he produced a story a week for the New York World, writing also for magazines. His first book, Cabbages and Kings (1904), depicted fantastic characters against exotic Honduran backgrounds. Both The Four Million (1906) and The Trimmed Lamp (1907) explored the lives of the multitude of New York in their daily routines and searchings for romance and adventure. Heart of the West (1907) presented accurate and fascinating tales of the Texas range.

Then in rapid succession came The Voice of the City (1908), The Gentle Grafter (1908), Roads of Destiny (1909), Options (1909), Strictly Business (1910), and Whirligigs (1910). Whirligigs contains perhaps Porter’s funniest story, “The Ransom of Red Chief.”

Despite his popularity, O. Henry’s final years were marred by ill health, a desperate financial struggle, and alcoholism. A second marriage in 1907 was unhappy. After his death three more collected volumes appeared: Sixes and Sevens (1911), Rolling Stones (1912), and Waifs and Strays (1917). Later seven fugitive stories and poems, O. Henryana (1920), Letters to Lithopolis (1922), and two collections of his early work on the Houston Post, Postscripts (1923) and O. Henry Encore (1939), were published. Foreign translations and adaptations for other art forms, including films and television, attest his universal application and appeal.

172. Mithali Raj

(Statistics : As on July 24, 2017)

Mithali Dorai Raj is an Indian cricketer and the captain of the Indian Women's cricket team in Tests and ODI. Often regarded as one of the greatest cricketing batswoman to have ever played the game, she is the highest run-scorer in women's international cricket and the only female cricketer to surpass the 6,000 run mark in ODIs. She is the first player to score 7 consecutive 50s in ODIs. Raj is the first captain (men or women) to lead India to an ICC ODI World Cup final twice - 2005 and 2017.

Mithali Raj was born on 3 December 1982 in Jodhpur. Mithali's Mother tongue is Tamil, her father is Dorai Raj, who was an Airman in the Indian Air Force, and mother is Leela Raj. Mithali started to play the game at the age of 10 and at the age of 17, she was picked for the Indian team. Her ODI debut was against Ireland at Milton Keynes in the year 1999. She lives in Hyderabad, Telangana. She attended Keyes high school for girls in Secunderabad. She started cricket coaching in her school days along with her elder brother. Mithali practised in Keyes Girls High School, Secunderabad often playing male cricketers in the nets. She has practiced classical dance for eight years and she quit dance to pursue her cricket career.

Raj has played both Test and One Day International cricket for India's women's cricket team. She was named among the probables in the 1997 Women's Cricket World Cup when she was just 14, but couldn't make it to the final squad. She made her One Day International debut in 1999 against Ireland at Milton Keynes and scored unbeaten 114 runs. She made her Test debut in the 2001-02 season against South Africa at Lucknow. On 17 August 2002, at the age of 19, in her third Test, she broke Karen Rolton's record of world’s highest individual Test score of 209*, scoring a new high of 214 against England in the second and final Test at County Ground, Taunton. The record has since been surpassed by Kiran Baluch of Pakistan who scored 242 against West Indies in March 2004.

Mithali was taken ill with a strain of typhoid in the CricInfo Women's World Cup in 2002, seriously hampering India's progress. However, she then led them to their first World Cup final in 2005, in South Africa, where they met Australia who proved just too strong. In August 2006, she led the side to their first ever Test and series victory in England and wrapped up the year winning the Asia Cup - the second time in 12 months - without dropping a single game.

She led the Indian team to the finals in the 2005 Women's Cricket World Cup where the team lost to Australia. She is a part-time leg-break bowler as well. She is a recipient of the Arjuna award for the year 2003. She currently tops the batting table with 703 ratings. Her composure when at the crease and ability to score briskly make her a dangerous cricketer. In addition to her ability with the bat, Mithali rolls her arm over bowling leg-spinners and providing variety to the attack.

At the 2013 Women's World Cup, Mithali Raj starred as the No.1 Cricketer in the ODI chart among women. She scored 100s: 1 and 50s: 4 in Test cricket, 100s: 5 and 50s: 40 with best bowling of 3/4 in ODI's and 50s: 10 in T20's.

in February 2017, she became the second player to make 5,500 runs in WODIs. Raj most matches captained player for india in ODI and T20I.
In July 2017, she became the first player to make 6,000 runs in WODIs.

Domestic career

Playing for Railways in the domestic competition, Mithali began by playing with stars like Purnima Rau, Anjum Chopra and Anju Jain for Air India.

Cricket performance

Mithali Raj held the record for the highest individual score by an Indian Woman Cricketer in a World Cup match (91 not out off 104 deliveries which included 9 fours) against New Zealand in Women's World Cup 2005. Harmanpreet Kaur overtook Mithali Raj by scoring a century (107 from 109 balls) in second match of ICC Women's World Cup 2013 against England.

Mithali is nicknamed as the "Tendulkar of Indian women's cricket", as she is currently the all-time leading run-scorer for India in all formats, including Tests, ODIs and T20Is.

During the 2017 Women's Cricket World Cup, Raj scored her seventh consecutive half-century and made a record for most consecutive fifties by a player.
Mithali Raj also is the 1st Indian & 5th woman cricketer overall to score over 1,000 World Cup runs.

Hi MathsIsFun,

I am a below average chess player. I chose the setting 'Medium'. I was beaten in the 10th move!

The setting works perfectly well in my case.

The summary of the game: 1. Nc3 e5  2. e4 Nc6  3. g4 Bc5  4. f3 Qh4+  5. Ke2 Nd4+  6. Kd3 Nf6  7. Be2 O-O  8. b3 b6  9. a4 Ba6+  10. Ke3 Nf5#

In my opinion, the program works remarkably well!

171. Colin Murdoch

Colin Albert Murdoch (6 February 1929 – 4 May 2008) was a New Zealand pharmacist and veterinarian who made a number of significant inventions, in particular the tranquilliser gun, the disposable hypodermic syringe and the child-proof medicine container. He had a total of 46 patents registered in his name.

Biographical background

Born in Christchurch, New Zealand, in 1929, to parents Mary Kathleen and Frank William James, Murdoch displayed a talent for chemistry at a very early age. Although he struggled through his schooling years with dyslexia, Murdoch already displayed an interest in both mechanical and technical skills. At the age of ten he successfully made gunpowder and came to the realization that an ignition could be caused by the mixing of certain nitrates and sulphuric acid. This discovery led the young Murdoch to build a successful firearm using a wick and a small asbestos-filled hammer.

At the age of 13 he was awarded the Royal Humane Society Medal for saving a drowning man in the New Brighton estuary.

Murdoch later came to outgrow his dyslexia and went on to study at The College of Pharmacy in Wellington. Following this, he completed a five-year apprenticeship and, like his father, became a pharmacist. He later studied to become a veterinarian. as he had an interest in not only human welfare, but also the welfare of animals.

Disposable hypodermic syringe

Both a pharmacist and a veterinarian, Murdoch was aware of the risks in reusing syringes. There was a high risk of passing infection from one patient to the next in both humans and animals, unless the glass syringe was sterilized accurately. Wanting to eliminate these risks, and needing more effective vaccination for his animal patients, Murdoch designed and invented the disposable hypodermic syringe, a plastic version of its glass predecessor. Murdoch presented the design to officials of the New Zealand Department of Health, who were skeptical, and believed it “too futuristic”, and that it would not be received well by both doctors and patients. Development of the syringe was held off for a few years due to lack of funding. Eventually, when he was granted both patents, Murdoch’s syringe became hugely successful, with millions used throughout the world every day. It is not widely known as a New Zealand design, although Murdoch's achievements have been covered in the New Zealand media.

Tranquilliser gun

In the 1950s, while working with colleagues who were studying introduced wild goat, deer and tahr populations in New Zealand, Murdoch had the idea that the animals would be much easier to catch, examine and release if a dose of tranquilliser could be administered by projection from afar. Murdoch became experienced with repairing and modifying guns during World War II, as rifles and shot guns were not being imported into New Zealand at that time. With both motive and experience, Murdoch went on to develop a range of rifles, darts and pistols, which have had an enormous impact on the treatment and study of animals around the world.

At the time Murdoch started testing his gun, the only tranquilliser drugs available were curare and alkaloids of nicotine, both of which tended to have fatal reactions in a high percentage of animals. In partnership with pharmaceutical companies, he helped develop more sophisticated drugs with precise and safe reactions.

Paxarms Limited (which stands for peace and arms), Murdoch’s own company, has developed various systems for administering veterinary products to a range of animals.

Recognition

Colin Murdoch has been acknowledged for his life's work. In 1976 he won three gold medals and a bronze at the World Inventions Fair in Brussels. The New Zealand Design Council has also honoured him and in 2000 he was made an Officer of the New Zealand Order of Merit for services to inventing. Time magazine included him in a list of the 100 most influential people of the South Pacific.

Despite the relative ubiquity of his inventions, Murdoch did not become rich because of them. He deliberately chose not to sue companies that violated his patents, satisfied instead that they were being put to good use.

In his final years he lived quietly in Timaru until his death from cancer.

170. Adam Osborne (March 6, 1939 – March 18, 2003) was a Thailand-born British-American author, book and software publisher, and computer designer who founded several companies in the United States and elsewhere.

Computers

Osborne was known to frequent the famous Homebrew Computer Club's meetings around 1975. He was best known for creating the first commercially available portable computer, the Osborne 1, released in April 1981. It weighed 24.5 pounds (12 kg), cost US$1795 - just over half the cost of a computer from other manufacturers with comparable features - and ran the popular CP/M 2.2 operating system. It was designed to fit under an airline seat. At its peak, Osborne Computer Corporation shipped 10,000 units of "Osborne 1" per month. Osborne was one of the first personal computing pioneers to understand fully that there was a wide market of buyers who were not computing hobbyists: the Osborne 1 included word processing and spreadsheet software. This was at a time when IBM would not bundle hardware and software with their PCs, selling separately the operating systems, monitors, and even cables for the monitor.

Adam Osborne's experience in the computer industry gave his new company credibility. Osborne Computer Corporation advertisements compared Adam Osborne's influence on the personal computer market to Henry Ford's influence on transportation. It is said that in 1983, Osborne bragged about two advanced new computers his company was developing. These statements destroyed consumer demand for the Osborne 1, and the resulting inventory glut forced Osborne Computer to file for bankruptcy on September 13, 1983. This phenomenon, a pre-announcement of a new product causing a catastrophic collapse in demand for older ones, became known as the Osborne effect, but according to some new sources the real reason for Osborne Computer's bankruptcy was management errors and insufficient cash flow.

Book

After Osborne Computer's collapse, Adam Osborne wrote a best-selling memoir of his experience, Hypergrowth: The Rise and Fall of the Osborne Computer Corporation with John C. Dvorak, which was published in 1984.

Kalam SAT is a microsatellite, named after former Indian president Dr. A. P. J. Abdul Kalam built by an Indian High school student team for participation in the Cubes in Space, a STEM-based education program by NASA, with an objective to teach school students (ages 11-18) how to design and compete to launch an experiment into space with a free opportunity to design experiments to be launched into space on a NASA rocket or balloon if there project is selected. Kalam SAT was launched by NASA along with several other Cube SAT micro satellite from other participants on 22 June 2017 from Wallops Island.

Although Kalam SAT has been reported to be the world’s lightest satellite, the term 'lightest' probably applies more to the KickSat Sprite—which is considerably smaller, lighter, and actually flown in orbit. Due to a malfunction, KickSat Sprites never deployed from KickSat, so that KickSat 1 orbited the earth as a 5.5 Kilograms 3U CubeSat. The Sprites burned up inside KickSat during re-entry. In its first deployment, KalamSat won't actually be a satellite since it won't reach orbit; it will only fly on a sounding rocket.

The probe was built by a team of 7 people led by Rifath Sharook, an 18 year old student from Pallapatti, Tamil Nadu, India, on behalf of Space Kidz India, a Research Organisation based on Chennai, as a part of a competition, named as - ‘Cubes in Space’. This contest was jointly organised by NASA and another organisation ‘I Doodle Learning’ which is a global education company. This will be the first time that a space probe, made by an Indian student, will be launched by NASA.

The weight of the probe is just 64 grams and it is fitted in a 3.8 centimeters cube. The probe is composed of 3-D printed reinforced carbon fiber polymer. Part of the components were supplied from India and other parts from abroad. The probe will be launched by a sub-orbital spaceflight. The expected time span of the mission (post flight) is 240 minutes. The tiny probe will be operated only for less than 12 minutes to demonstrate the performance of 3-D printed carbon fiber in a micro-gravity environment of space.
