World Day Against Cyber Censorship

World Day Against Cyber-Censorship takes place annually on March 12. It aims to rally computer users in fighting repression of online speech. Reporters Without Borders was also created this day to celebrate the work of brave individuals who have promoted free expression on the Internet. The annual Netizen Prize is awarded to bloggers, online journalists, and cyber-dissidents, who have demonstrated exceptional dedication to this cause. It was first observed on March 12, 2008 at the request of Reporters Without Borders and Amnesty International. A letter written by Jean-Francois Julliard, Secretary-General of Reporters Without Borders, and Larry Cox, Executive Director of Amnesty International, was sent to the Chief Executive Officers of Google, Yahoo! & Microsoft Corporation to request observation of the day.

The Electronic Frontier Foundation remains dedicated to reporting cases of online censorship from all regions of the world, and emphasize the importance of online anonymity in preserving individuals’ right to free speech, with an ongoing feature, This Week in Censorship, which covers global stories of imprisoned bloggers, filtered content, blocked websites, and instances of Internet disconnection. A broad array of reasons are offered as justification for censorship. Bloggers in Thailand face imprisonment for criticizing the monarch. In Pakistan, the Telecommunications Authority has blocked websites, banned words from SMS texts, and most recently, has released a request for proposals to build a national blocking and filtering system: All in the name of fighting “obscene content.” The Turkish government has implemented a so-called “democratic” opt-in filtering mechanism for content that is deemed unsuitable for children and families.

Another common trend is censorship enabled in the name of battling copyright violations. Through our Global Chokepoints project, we are monitoring instances of pro-copyright laws that justify filtering of content, websites blockages, or Internet disconnection to fight infringement. Censorship remains rampant in the Middle Eastern region. In Syria, Iran, and elsewhere, bloggers continue to face imprisonment, and common users have limited access to content online due to state-mandated blocking and filtering programs. Another ongoing issue being covered are authoritarian states using Western-based surveillance technologies to monitor and spy on their citizens. State authorities can use the collected data to arrest, harass, or torture individuals accused of participating in political dissent.

International Games Masters Day

International Games Master’s Day takes place anuually on 4 March. GM’s Day was born on EN World in December 2002. Originally a simple messageboard post by EN World member Spunkrat (later renamed Heathen72), the idea quickly gained popularity, championed by Mark Clover of Creative Mountain Games and, of course, EN World itself.

GM’s Day is an annual day to show your GAmes Master, DUngeon Master, Storyteller, or Referee) how much you appreciate them. Publishers and retail outlets across the world now join in GM’s Day, offering discounts, sales, and other cool stuff. From a single messageboard thread, GM’s Day now includes hundreds of publishers, websites, bloggers, such as RPGNow/DriveThruRPG’s who host a massive GM’s Day sale. Marth 4th is also the anniversary of the sad passing of Dungeons & Dragons co-creator Gary Gygax who sadly died 4 March 2008.

Toy Soldier Day

The name of Toy Soldier Day is a bit deceiving. Rather than collecting or displaying plastic toys or replicas, Toy Soldier Day is actually intended to unite fans of various role-playing activities. Toy Soldier Day was orignally started as a fan club by The Army of Toy Soldiers to give recognition to talented street performer, including musicians and the internet personality Dr. Steel who started his career in 1999 in Los Angeles, Putting on shows combining puppetry and video projections to help his audience better understnd the meanings of his steampunk songs. countless fans of stage persona Dr. Steel celebrate Toy Soldier Day annually Including nurses, scouts and soldiers) one of the primary goals of Toy Soldier Day is to collaborate, compare and share costume ideas.

Fluoride Day

Fluoride day takes place annually on 25 January. Fluoride is an inorganic, monatomic anion with the chemical formula F− whose salts are typically white or colorless. Fluoride salts typically have distinctive bitter tastes, and are odorless. Its salts and minerals are important chemical reagents and industrial chemicals, mainly used in the production of hydrogen fluoride for fluorocarbons. Fluoride is classified as a weak base since it only partially associates in solution, but concentrated fluoride is corrosive and can attack the skin. Fluoride is the simplest fluorine anion. In terms of charge and size, the fluoride ion resembles the hydroxide ion. Fluoride ions occur on earth in several minerals, particularly fluorite, but are present only in trace quantities in bodies of water in nature. Fluorides include compounds that contain both ionic fluoride and those where fluoride does not dissociate. The nomenclature does not distinguish these situations. For example, sulfur hexafluoride and carbon tetrafluoride are not sources of fluoride ions under ordinary conditions.

The systematic name fluoride, the valid IUPAC name, is determined according to the additive nomenclature. However, the name fluoride is also used in compositional IUPAC nomenclature which does not take the nature of bonding involved into account. Fluoride is also used non-systematically, to describe compounds which release fluoride upon dissolving. Hydrogen fluoride is itself an example of a non-systematic name of this nature. However, it is also a trivial name, and the preferred IUPAC name for fluorane. Fluorine is estimated to be the 13th most abundant element in the earth’s crust and is widely dispersed in nature, almost entirely in the form of fluorides. Many minerals are known, but of paramount commercial importance is fluorite (CaF2), which is roughly 49% fluoride by mass. The soft, colorful mineral is found worldwide. Fluoride is also naturally present at low concentration in most fresh and saltwater sources and may also be present in rainwater. Seawater fluoride levels are usually in the range of 0.86 to 1.4 mg/L, and average 1.1 mg/L (milligrams per litre). For comparison, chloride concentration in seawater is about 19 g/L. The low concentration of fluoride reflects the insolubility of the alkaline earth fluorides, e.g., CaF2.

Salts containing fluoride are numerous and adopt myriad structures. Typically the fluoride anion is surrounded by four or six cations, as is typical for other halides. Sodium fluoride and sodium chloride adopt the same structure. For compounds containing more than one fluoride per cation, the structures often deviate from those of the chlorides, as illustrated by the main fluoride mineral fluorite (CaF2) where the Ca2+ ions are surrounded by eight F− centers. In CaCl2, each Ca2+ ion is surrounded by six Cl− centers. The difluorides of the transition metals often adopt the rutile structure whereas the dichlorides have cadmium chloride structures. Upon treatment with a standard acid, fluoride salts convert to hydrogen fluoride and metal salts. With strong acids, it can be doubly protonated to give H2F. Oxidation of fluoride gives fluorine. Solutions of inorganic fluorides in water contain F− and bifluoride HF−2. Few inorganic fluorides are soluble in water without undergoing significant hydrolysis. In terms of its reactivity, fluoride differs significantly from chloride and other halides, and is more strongly solvated in protic solvents due to its smaller radius/charge ratio. Its closest chemical relative is hydroxide, since both have similar geometries. When relatively unsolvated, for example in nonprotic solvents, fluoride anions are called “naked”.

Naked fluoride is a very strong Lewis base, and reacts with Lewis acids, forming strong adducts. Naked fluoride salts have been prepared as tetramethylammonium fluoride, tetramethylphosphonium fluoride, and tetrabutylammonium fluoride. Many so-called naked fluoride sources are in fact bifluoride salts. In late 2016 a new type of imidazolium fluoride was synthesized that is termodynamically stable example of a “naked” fluoride source in acetonitrile and its reactivity shows significant potential. At physiological pHs, hydrogen fluoride is usually fully ionised to fluoride. In biochemistry, fluoride and hydrogen fluoride are equivalent. Fluorine, in the form of fluoride, is considered to be a micronutrient for human health, necessary to prevent dental cavities, and to promote healthy bone growth. The tea plant (Camellia sinensis L.) is a known accumulator of fluorine compounds, released upon forming infusions such as the common beverage. The fluorine compounds decompose into products including fluoride ions. Fluoride is the most bioavailable form of fluorine, and as such, tea is potentially a vehicle for fluoride dosing.

Approximately, 50% of absorbed fluoride is excreted renally with a twenty-four-hour period. The remainder can be retained in the oral cavity, and lower digestive tract. Fasting dramatically increases the rate of fluoride absorption to near 100%, from a 60% to 80% when taken with food. A 2013 study, discovered that consumption of one litre of tea a day, can potentially supply the daily recommended intake of 4 mg per day. Some lower quality brands can supply up to a 120% of this amount. Fasting can increase this to 150%. The study indicates that tea drinking communities are at an increased risk of dental and skeletal fluorosis, in the case where water fluoridation is in effect. Fluoride ion in low doses in the mouth reduces tooth decay. For this reason, it is used in toothpaste and water fluoridation. However At much higher doses and frequent exposure, fluoride causes health complications and can be toxic.

Fluoride salts and hydrofluoric acid also have industrial value. Compounds with C-F bonds fall into the realm of organofluorine chemistry. The main uses of fluoride, in terms of volume, are in the production of cryolite, Na3AlF6. It is used in aluminium smelting. Formerly, it was mined, but now it is derived from hydrogen fluoride. Fluorite is used on a large scale to separate slag in steel-making. Mined fluorite (CaF2) is a commodity chemical used in steel-making. Hydrofluoric acid and its anhydrous form, hydrogen fluoride, is also used in the production of fluorocarbons. Hydrofluoric acid has a variety of specialized applications, including its ability to dissolve glass.

Wikipedia Day

Wikipedia day takes place annually on 15 January to commemorate the launch of the online web-based encyclopedia Wikipedia on January 15, 2001. It was launched by Jimmy Wales and Larry Sanger who coined the name, Wikipedia as a portmanteau of wiki and “encyclopedia”.

Wikipedia is a multilingual, web-based, free encyclopedia based on a model of openly editable and viewable content, a wiki. It is the largest and most popular general reference work on the World Wide Web, and is one of the most popular websites by Alexa rank. It is owned and supported by the Wikimedia Foundation, a non-profit organization that operates on money it receives from donors.

The roots of Wikipedia begin as a complementary project for Nupedia, a free online English-language encyclopedia project whose articles were written by experts and reviewed under a formal process. It was founded on March 9, 2000, under the ownership of Bomis, a web portal company. Its main figures were Bomis CEO Jimmy Wales and Larry Sanger, editor-in-chief for Nupedia and later Wikipedia. Nupedia was initially licensed under its own Nupedia Open Content License, but even before Wikipedia was founded, Nupedia switched to the GNU Free Documentation License at the urging of Richard Stallman. Wales is credited with defining the goal of making a publicly editable encyclopedia, while Sanger is credited with the strategy of using a wiki to reach that goal. On January 10, 2001, Sanger proposed on the Nupedia mailing list to create a wiki as a “feeder” project for Nuped

Wikipeadia was Initially an English-language encyclopedia, however versions in other languages were quickly developed. With 5,789,328 articles, the English Wikipedia is the largest of the more than 290 Wikipedia encyclopedias. Overall, Wikipedia comprises more than 40 million articles in 301 different languages and by February 2014 it had reached 18 billion page views and nearly 500 million unique visitors per month.

In 2005, Nature published a peer review comparing 42 science articles from Encyclopædia Britannica and Wikipedia and found that Wikipedia’s level of accuracy approached that of Britannica. Time magazine stated that the open-door policy of allowing anyone to edit had made Wikipedia the biggest and possibly the best encyclopedia in the world, and was a testament to the vision of Jimmy Wales. However Wikipedia has been criticized for exhibiting systemic bias, for presenting a mixture of “truths, half truths, and some falsehoods”, and for being subject to manipulation and spin in controversial topics. In 2017, Facebook announced that it would help readers detect fake news by suitable links to Wikipedia articles. YouTube announced a similar plan in 2018.

Charles Babbage

Mathematician, philosopher, inventor and mechanical engineer and English Polymath Charles Babbage, FRS was born 26 December 1791. Babbage attended country school inAlphington near Exeter, then attended King Edward VI Grammar School in Totnes, South Devon, but his health forced him back to private tutors for a time Babbage then joined Holmwood academy, in Baker Street, Enfield,Middlesex, The academy’s library kindled Babbage’s love of mathematics. He studied with two more private tutors after leaving the academy. He was brought home, to study at the Totnes school: Babbage was accepted by Cambridge University and arrived at Trinity College, Cambridge, in October 1810, where he formed the Analytical society in 1812 with John Herschel and George Peacock ; Babbage was also a member of The Ghost Club, which investigated supernatural phenomena, and the Extractors Club, dedicated to liberating its members from the madhouse, should any be committed to one .In 1812 Babbage transferred to Peterhouse, Cambridge. He was the top mathematician there, but did not graduate with honours, receiving a degree without examination instead in 1814 after having defended a thesis that was considered blasphemous in the preliminary public disputation;

In 1815 Babbage lectured at the Royal Institution on astronomy and was elected a Fellow of the Royal Society in 1816. After graduation, Babbage and Herschel visited the Society of Arcueil in Paris, meeting leading French mathematicians and physicists and also worked on a basic explanation of the Electrodynamics of Arago’s rotation with Herschel, and Michael Farraday. These are now part of the theory of eddy currents. He also worked on the unification of electromagnetics. Babbage was also interested in the Coarative View of the Various institutions for the Assurance of Lives and calculated Acturial tables for an insurance Company using Equitable Society Mortality Data from 1762. Babbage helped found the Astronomical Society in 1820, whose aims were to reduce astronomical calculations to a more standard form, and publish the data. In 1824 Babbage won the Astronomical Society’s Gold Medal, “for his invention of an engine for calculating mathematical and astronomical tables” to overcome errors made in tables by mechanisation and to improve the Nautical Almanac after decrepencies were found in traditional calculations. Babbage also helped establish a modern postal system, with his friend Thomas Frederick Colby, And introduced the Uniform Fourpenny Post supplanted by the Uniform Penny Post. In 1816 Babbage, Herschel and Peacock published a translation from French of the lectures of Sylvestre Lacroix concerning Calculus, the Formal Power Series which affected functional equations (including the difference equations fundamental to the difference engine) and operator (D-module) methods for differential equations. He also originated the concept of a programmable computer” and invented the first mechanical computer that eventually led to more complex designs.

The analogy of difference and differential equations was notationally changing Δ to D, as a “finite” difference becomes “infinitesimal”. These symbolic directions became popular, as operational calculus, and pushed to the point of diminishing returns. Woodhouse had already founded this second “British Lagrangian School” Babbage worked intensively on functional equations in general, influenced by Arbogast’s ideas. From 1828 to 1839 Babbage was Lucasian Professor of Mathematics at Cambridge. Not a conventional resident don, and inattentive to teaching, he wrote three topical books during this period of his life. He was elected a Foreign Honorary Member of theAmerican Academy of Arts and Sciences in 1832. Babbage planned to lecture in 1831 on political economy. Babbage’s reforming direction Aiming to make university education more inclusive, with universities doing more for research, a broader syllabus and more interest in applications, but the idea was rejected. Another controversy Babbage had with Richard Jones lasted for six years and he never gave another lecture. Babbage also tried to enter politics, his views included disestablishment of the Church of England, a broader political franchise, and inclusion of manufacturers as stakeholders. He twice stood for Parliament as a candidate for the borough of Finsbury. In 1832 he came in third among five candidates, missing out by some 500 votes in the two-member constituency when two other reformist candidates, Thomas Wakley and Christopher Temple, split the vote. Babbage wrote another book Reflections on the Decline of Science and some of its Causes (1830) attacking the establishment and aiming to improve British science, by ousting Davies Gilbert as President of the Royal Society. Babbage also wished to become the junior secretary of the Royal Society, as Herschel was the senior, but failed after antagonizing Humphry Davy. subsequently the British Association for the Advancement of Science (BAAS) was formed in 1831.

Babbage used symbols to express the actions of his Difference and Analytical Engines in his influential book Economy of Machinery and Manufactures, which dealt with the organisation of industrial production. And An essay on the general principles which regulate the application of machinery to manufactures and the mechanical arts, was featured in the Encyclopædia Metropolitana. In his book Babbage developed the schematic classification of machines, whether for Domestic or industrial use andThe book also contained ideas on rational design in factories, and profit sharing and described The Babbage Principal. This discussed the commercial advantages available with more careful division of labour This principal had already been mentioned in the work of Melchiorre Gioia in 1815.The term was introduced in 1974 by Harry Braverman. Related formulations are the “principle of multiples” of Philip Sargant Florence, and the “balance of processes”. Babbage noticed that skilled workers typically spend parts of their time performing tasks that are below their skill level. If the labour process can be divided among several workers, labour costs may be cut by assigning only high-skill tasks to high-cost workers, restricting other tasks to lower-paid workers And that apprenticeship can be taken as fixed cost but returns to scale are available favoring the factory system. He also published a detailed breakdown of the cost structure of book publishing exposing the trade’s profitability,much to the chagrin of many publishers and namedthe organisers of the trade’s restrictive practices.

Babbage’s theories also influenced the 1851 Great Exhibition his views having a strong effect on many. Karl Marx argued that the source of the productivity of the factory system was the combination of the division of labour with machinery but mentioned that the motivation for division of labour was often for the sake of profitability, rather than productivity. Babbage also influenced the economic thinking of John Stuart Mill, George Holyoake, the economist Claude Lucien Bergery, William Jevons and Charles Fourier among others

In 1837, Babbage published On the Power, Wisdom and Goodness of God. A work of natural theology in which Babbage favored uniformitarianism preferring the conception of creation in which natural law dominated, removing the need for “contrivance. It incorporated extracts from related correspondence of Herschel withCharles Lyell. Babbage put forward the thesis that God had the omnipotence and foresight to create as a divine legislator. He could make laws which then produced species at the appropriate times, rather than continually interfering with ad hoc miracles each time a new species was required. The British Association as inspired by the Deutsche Naturforscher-Versammlung, founded in 1822. It rejected romantic science as well as metaphysics, and started to entrench the divisions of science from literature, and professionals from amateurs. Babbage also identified closely with industrialists And Suggested that industrial society was the culmination of human development. In 1838 a clash with Roderick Murchison led to his withdrawal from further involvement and he also resigned as Lucasian professor,

His interests became more focussed, on computation and metrology, and on international contacts And announced A project to tabulate all physical constants (referred to as “constants of nature”, a phrase in itself a neologism), and then to compile an encyclopedic work of numerical information. He was a pioneer in the field of “absolute measurement”.] His ideas followed on from those of Johann Christian Poggendorff, and were mentioned to Brewster in 1832. There were to be 19 categories of constants, and Ian Hacking sees these as reflecting in part Babbage’s “eccentric enthusiasms” Babbage’s paper On Tables of the Constants of Nature and Art was reprinted by the Smithsonian Institution in 1856, with an added note that the physical tables of Arnold Henry Guyot “will form a part of the important work proposed in this article”.Exact measurement was also key to the development of machine tools. Here again Babbage is considered a pioneer, with Henry Maudslay, William Sellers, and Joseph Whitworth

Babbage also met the the Engineers Marc Brunel and Joseph Clement at the Royal Society And introduced them to Isambard Kingdom Brunel in 1830, for a contact with the proposed Bristol & Birmingham Railway. He also carried out studies, around 1838, showing the superiority of the broad gauge for railways, used by Brunel’s Great Western Railway ln 1838, And invented the pilot (also called a cow-catcher), the metal frame attached to the front of locomotives that clears the tracks of obstacles; he also constructed a dynamometer car. His eldest son, Benjamin Herschel Babbage, also worked as an engineer for Brunel on the railways before emigrating to Australia in the 1850s. Babbage also invented an ophthalmoscope, however the optician Thomas Wharton Jones, ignored it and It Was only widely used after being independently invented by Hermann von Helmholtz.

Babbage also decoded Vigenère’s autokey cipher during the Crimean War His discovery being kept a military secret And later wrote a letter anonymously to the Journal of the Society for Arts concerning “Cypher Writing” . Babbage lived and worked for over 40 years at 1 Dorset Street, Marylebone, where he died, at the age of 79, on 18 October 1871; he was buried in London’s Kensal Green Cemetery. According to Horsley, Babbage died “of renal inadequacy, secondary to cystitis.” He had declined both a knighthood and baronetcy. He also argued against hereditary peerages, favoring life peerages instead .In 1983 the autopsy report for Charles Babbage was discovered and later published by his great-great-grandson A copy of the original is also available. Half of Babbage’s brain is preserved at the Hunterian Museum in the Royal College of Surgeons in London The other half of Babbage’s brain is on display in the Science Museum, London.
