The Athens Metro is a rapid-transit system in Greece which serves the Athens conurbation and parts of East Attica. It incorporates the former Athens-Piraeus Electric Railways, which opened as a conventional steam railway in 1869, was electrified in 1904, is now part of Line 1. Beginning in 1991, Attiko Metro constructed and extended Lines 2 and 3 and the Attiko Metro Operations Company operated these lines from 2000 to 2011; the metro network merged in 2011 when the Greek government created the Urban Rail Transport Company, a subsidiary of the Athens Urban Transport Organisation. First Chairman and CEO of the merged company became Kostas Vassiliadis, a former Chief Engineer and CEO of Athens-Piraeus Electric Railways; the system is noted for being modern and efficient, in its own right and in comparison to other subway systems elsewhere. It has changed Athens by providing a much-needed solution to the city's traffic and air pollution problem, as well as revitalising many of the areas it serves.
An extension of Line 3 is under construction towards Piraeus and other extensions of existing lines, as well as a new line, are under consideration. The Athens Metro is connected with the other means of public transport, such as buses, the Athens Tram and the Proastiakos suburban railway; the Athens Metro is hailed for its modernity and many of its stations feature works of art and displays of the archeological remains found during its construction. Photography and video-taking is permitted across the whole network and street photographers work in Athens Metro; until 28 January 2000, Line 1 was the only rapid-transit line in Piraeus. The Athens and Piraeus Railway Company opened the line on 27 February 1869 as a steam railway between Piraeus and Thiseio, it was electrified in 1904, extended in stages to Kifisia in 1957. From 1976 to 16 June 2011, the Athens-Piraeus Electric Railway Company operated Line 1 independently from the rest of the metro and tram networks. Unlike Lines 2 and 3, it runs entirely above ground.
Since the current Line 1 opened the government has proposed many expansions to the subway network, including a 1963 plan for a fourteen-line subway network. Construction of Lines 2 and 3 began in November 1992 to decrease traffic congestion and improve Athens' air quality by reducing its smog level. Both lines were constructed underground. Lines 2 and 3, built by Attiko Metro and operated until 2011 by Attiko Metro Operations Company, are known as the red and blue lines and were inaugurated in January 2000. Line 3 was extended to the Eleftherios Venizelos International Airport in summer 2004, Line 2 was extended to Anthoupoli and Helliniko in 2013; until 17 June 2011, the operational management of the Athens Metro network was similar to that of the London Underground network before the creation of the London Passenger Transport Board and the absorption of the Metropolitan Railway on 1 July 1933. The Greek government attempted to absorb ISAP into Attiko Metro under Law 2669/1998 so the latter would be responsible for the whole network, but this initiative failed.
Athens Metro operations were consolidated when the Greek government enacted Law 3920/2011, replacing AMEL, ISAP and Athens Tram with Urban Rail Transport, a subsidiary of OASA. The modern incarnation of Line 1 is 25.6-kilometre long, serves 24 stations. Together, Lines 2 and 3 are 58.9-kilometre long, serve 41 stations. The three-line Athens Metro network serves 61 stations, it owns and operates 57 of them, OSE owns the remainder on the airport section. The network has four metro interchanges, enabling the lines to interchange with each other at least once; each line has at least one station connecting with the Proastiakos Suburban Railway and Athens Tram. Line 2 and the Attiko Metro portion of Line 3 is underground. Line 1 is in the open, with a tunnel section in central Athens; the airport section of Line 3, east of the tunnel portal near Doukissis Plakentias, is open. In the tunnel sections up and down lines share a common tunnel, except for approaches to stations with an island platform; the network uses standard gauge electric trains which in most places run on 750 V DC third rail, but the section of Line 3 running to the airport requires trains which can use overhead lines of 25 kV AC, 50 Hz.
Line 1 has had its own fleet, but there are rail connections between Lines 1 and 2 near Attiki and between Lines 2 and 3 near Syntagma. Train maintenance facilities are located at Attiki, Irini and Thiseio for Line 1, Doukissis Plakentias and Sepolia for Lines 2 and 3; as of April 2008 the blue line was 16.4 km long, not including the suburban railway line to the airport or 21.2 km of the line it shares with Proastiakos, the Athens suburban railway system. As of July 2008, the red line was 10.9 km, bringing the overall length of the green and blue lines to 74 km. The Athens Metro's three lines carry 1,353,000 passengers daily; the Athens Metro classifies rolling stock by "batch" for Line 1 and "generation" for Lines 2 and 3 because ISAP and AMEL used different classification systems for rolling stock before consolidation. Six types of rolling stock operate on the network, all equipped with third rail current collection systems.
Google LLC is an American multinational technology company that specializes in Internet-related services and products, which include online advertising technologies, search engine, cloud computing and hardware. It is considered one of the Big Four technology companies, alongside Amazon and Facebook. Google was founded in 1998 by Larry Page and Sergey Brin while they were Ph. D. students at Stanford University in California. Together they own about 14 percent of its shares and control 56 percent of the stockholder voting power through supervoting stock, they incorporated Google as a held company on September 4, 1998. An initial public offering took place on August 19, 2004, Google moved to its headquarters in Mountain View, nicknamed the Googleplex. In August 2015, Google announced plans to reorganize its various interests as a conglomerate called Alphabet Inc. Google is Alphabet's leading subsidiary and will continue to be the umbrella company for Alphabet's Internet interests. Sundar Pichai was appointed CEO of Google.
The company's rapid growth since incorporation has triggered a chain of products and partnerships beyond Google's core search engine. It offers services designed for work and productivity, email and time management, cloud storage, instant messaging and video chat, language translation and navigation, video sharing, note-taking, photo organizing and editing; the company leads the development of the Android mobile operating system, the Google Chrome web browser, Chrome OS, a lightweight operating system based on the Chrome browser. Google has moved into hardware. Google has experimented with becoming an Internet carrier. Google.com is the most visited website in the world. Several other Google services figure in the top 100 most visited websites, including YouTube and Blogger. Google is the most valuable brand in the world as of 2017, but has received significant criticism involving issues such as privacy concerns, tax avoidance, antitrust and search neutrality. Google's mission statement is "to organize the world's information and make it universally accessible and useful".
The companies unofficial slogan "Don't be evil" was removed from the company's code of conduct around May 2018. Google began in January 1996 as a research project by Larry Page and Sergey Brin when they were both PhD students at Stanford University in Stanford, California. While conventional search engines ranked results by counting how many times the search terms appeared on the page, the two theorized about a better system that analyzed the relationships among websites, they called this new technology PageRank. Page and Brin nicknamed their new search engine "BackRub", because the system checked backlinks to estimate the importance of a site, they changed the name to Google. The domain name for Google was registered on September 15, 1997, the company was incorporated on September 4, 1998, it was based in the garage of a friend in California. Craig Silverstein, a fellow PhD student at Stanford, was hired as the first employee. Google was funded by an August 1998 contribution of $100,000 from Andy Bechtolsheim, co-founder of Sun Microsystems.
Google received money from three other angel investors in 1998: Amazon.com founder Jeff Bezos, Stanford University computer science professor David Cheriton, entrepreneur Ram Shriram. Between these initial investors and family Google raised around 1 million dollars, what allowed them to open up their original shop in Menlo Park, California After some additional, small investments through the end of 1998 to early 1999, a new $25 million round of funding was announced on June 7, 1999, with major investors including the venture capital firms Kleiner Perkins and Sequoia Capital. In March 1999, the company moved its offices to Palo Alto, home to several prominent Silicon Valley technology start-ups; the next year, Google began selling advertisements associated with search keywords against Page and Brin's initial opposition toward an advertising-funded search engine. To maintain an uncluttered page design, advertisements were text-based. In June 2000, it was announced that Google would become the default search engine provider for Yahoo!, one of the most popular websites at the time, replacing Inktomi.
In 2003, after outgrowing two other locations, the company leased an office complex from Silicon Graphics, at 1600 Amphitheatre Parkway in Mountain View, California. The complex became known as the Googleplex, a play on the word googolplex, the number one followed by a googol zeroes. Three years Google bought the property from SGI for $319 million. By that time, the name "Google
Pefki is a suburb in the northeastern part of the Athens agglomeration, Greece. Since the 2011 local government reform it is part of the municipality Lykovrysi-Pefki, of which it is the seat and a municipal unit, it is part of North Athens regional unit. Pefki is situated 10 kilometres northeast of Athens city centre; the municipal unit has an area of 2.176 km2. The built-up area of Pefki is continuous with those of the neighbouring suburbs Irakleio, Lykovrysi and Marousi. Pefki consists of two areas: Ano Pefki and Kato Pefki.

Bayer AG is a German multinational pharmaceutical and life sciences company and one of the largest pharmaceutical companies in the world. Headquartered in Leverkusen, where its illuminated corporate logo, the Bayer cross, is a landmark, Bayer's areas of business include human and veterinary pharmaceuticals; the company is a component of the Euro Stoxx 50 stock market index. Werner Baumann has been CEO since 2016. Founded in Barmen in 1863 as a dyestuffs factory, Bayer's first and best-known product was aspirin. In 1898 Bayer trademarked the name heroin for the drug diacetylmorphine and marketed it as a cough suppressant and non-addictive substitute for morphine until 1910. Bayer introduced phenobarbital. In 1925 Bayer was one of six chemical companies that merged to form IG Farben, the world's largest chemical and pharmaceutical company; the Allied Control Council seized IG Farben after World War II, because of its role in the Nazi war effort and involvement in the Holocaust, which included using slave labour from concentration camps.
It was split into its six constituent companies in 1951 split again into three: BASF, Bayer and Hoechst. Bayer played a key role in the Wirtschaftswunder in post-war West Germany regaining its position as one of the world's largest chemical and pharmaceutical corporations. In 2006 the company acquired Schering, in 2014 it acquired Merck & Co.'s consumer business, with brands such as Claritin, Coppertone and Dr. Scholl's, in 2018 it acquired Monsanto, a leading producer of genetically engineered crops, for $63 billion. Bayer CropScience develops genetically modified pesticides. Bayer AG was founded as a dyestuffs factory in 1863 in Barmen, Germany, by Friedrich Bayer and his partner, Johann Friedrich Weskott, a master dyer. Bayer was responsible for the commercial tasks. Fuchsine and aniline became; the headquarters and most production facilities moved from Barmen to a larger area in Elberfeld in 1866. Friedrich Bayer, son of the company's founder, was a chemist and joined the company in 1873. After the death of his father in 1880, the company became a joint-stock company, Farbenfabriken vorm.
Friedr. Bayern & Co known as Elberfelder Farbenfabriken. A further expansion in Elberfeld was impossible, so the company moved to the village Wiesdorf at Rhein and settled in the area of the alizarin producer Leverkus and Sons. A new city, was founded there in 1930 and became home to Bayer AG's headquarters; the company's corporate logo, the Bayer cross, was introduced in 1904, consisting of the word BAYER written vertically and horizontally, sharing the Y and enclosed in a circle. An illuminated version of the logo is a landmark in Leverkusen. Bayer's first major product was acetylsalicylic acid—first described by French chemist Charles Frederic Gerhardt in 1853—a modification of salicylic acid or salicin, a folk remedy found in the bark of the willow plant. By 1899 Bayer's trademark Aspirin was registered worldwide for Bayer's brand of acetylsalicylic acid, but it lost its trademark status in the United States and the United Kingdom after the confiscation of Bayer's US assets and trademarks during World War I by the United States, because of the subsequent widespread usage of the word.
The term aspirin continued to be used in the US, UK and France for all brands of the drug, but it is still a registered trademark of Bayer in over 80 countries, including Canada, Mexico and Switzerland. As of 2011 40,000 tons of aspirin were produced each year and 10–20 billion tablets consumed in the United States alone for prevention of cardiovascular events, it is on the WHO Model List of Essential Medicines, the most important medications needed in a basic health system. There is an unresolved controversy over the roles played by Bayer scientists in the development of aspirin. Arthur Eichengrün, a Bayer chemist, said he was the first to discover an aspirin formulation that did not have the unpleasant side effects of nausea and gastric pain, he said he had invented the name aspirin and was the first person to use the new formulation to test its safety and efficacy. Bayer contends. Various sources support the conflicting claims. Most mainstream historians attribute the invention of aspirin to Hoffmann and/or Eichengrün.
Heroin, now illegal as an addictive drug, was introduced as a non-addictive substitute for morphine, trademarked and marketed by Bayer from 1898 to 1910 as a cough suppressant and over-the-counter treatment for other common ailments, including pneumonia and tuberculosis. Bayer scientists were not the first to make heroin, but the company led the way in commercializing it. Heroin was a Bayer trademark until after World War I. In 1903 Bayer licensed the patent for the hypnotic drug diethylbarbituric acid from its inventors Emil Fischer and Joseph von Mering, it was marketed under the trade name Veronal as a sleep aid beginning in 1904. Systematic investigations of the effect of structural changes on potency and duration of action at Bayer led to the discovery of phenobarbital in 1911 and the discovery of its potent anti-epileptic activity in 1912. Phenobarbital was among the most used drugs for the treatment of epilepsy through the 1970s, as of 2014 it remains on the World Health Organization's list of essential medications.
During World War I, Bayer's assets, including the rights to
Nerantziotissa station is a complex of two train stations located in Maroussi, Greece, a northern suburb of Athens. The first is a station of the Athens Metro and the second is a suburban railway station, its name comes from Panagia Nerantziotissa, located nearby. The station is near a large US-style shopping centre, it is close to Athens Olympic Sports Complex. Nerantziotissa station was built for the 2004 Olympic Games; as of 2013 the station is served by three trains per hour to the airport, two to Ano Liosia and one to Kiato.

A time zone is a region of the globe that observes a uniform standard time for legal and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions because it is convenient for areas in close commercial or other communication to keep the same time. Most of the time zones on land are offset from Coordinated Universal Time by a whole number of hours, but a few zones are offset by 30 or 45 minutes; some higher latitude and temperate zone countries use daylight saving time for part of the year by adjusting local clock time by an hour. Many land time zones are skewed toward the west of the corresponding nautical time zones; this creates a permanent daylight saving time effect. Before clocks were first invented, it was common practice to mark the time of day with apparent solar time – for example, the time on a sundial –, different for every location and dependent on longitude; when well-regulated mechanical clocks became widespread in the early 19th century, each city began to use some local mean solar time.
Apparent and mean solar time can differ by up to around 15 minutes because of the elliptical shape of the Earth's orbit around the Sun and the tilt of the Earth's axis. Mean solar time has days of equal length, the difference between the two sums to zero after a year. Greenwich Mean Time was established in 1675, when the Royal Observatory was built, as an aid to mariners to determine longitude at sea, providing a standard reference time while each city in England kept a different local time. Local solar time became inconvenient as rail transport and telecommunications improved, because clocks differed between places by amounts corresponding to the differences in their geographical longitudes, which varied by four minutes of time for every degree of longitude. For example, Bristol is about 2.5 degrees west of Greenwich, so when it is solar noon in Bristol, it is about 10 minutes past solar noon in London. The use of time zones accumulates these differences into longer units hours, so that nearby places can share a common standard for timekeeping.
The first adoption of a standard time was on December 1, 1847, in Great Britain by railway companies using GMT kept by portable chronometers. The first of these companies to adopt standard time was the Great Western Railway in November 1840; this became known as Railway Time. About August 23, 1852, time signals were first transmitted by telegraph from the Royal Observatory, Greenwich. Though 98% of Great Britain's public clocks were using GMT by 1855, it was not made Britain's legal time until August 2, 1880; some British clocks from this period have two minute hands—one for the local time, one for GMT. Improvements in worldwide communication further increased the need for interacting parties to communicate mutually comprehensible time references to one another; the problem of differing local times could be solved across larger areas by synchronizing clocks worldwide, but in many places that adopted time would differ markedly from the solar time to which people were accustomed. On November 2, 1868, the British colony of New Zealand adopted a standard time to be observed throughout the colony, was the first country to do so.
It was based on the longitude 172°30′ East of Greenwich, 11 hours 30 minutes ahead of GMT. This standard was known as New Zealand Mean Time. Timekeeping on the American railroads in the mid-19th century was somewhat confused; each railroad used its own standard time based on the local time of its headquarters or most important terminus, the railroad's train schedules were published using its own time. Some junctions served by several railroads had a clock for each railroad, each showing a different time. Charles F. Dowd proposed a system of one-hour standard time zones for American railroads about 1863, although he published nothing on the matter at that time and did not consult railroad officials until 1869. In 1870 he proposed four ideal time zones, the first centered on Washington, D. C. but by 1872 the first was centered with geographic borders. Dowd's system was never accepted by American railroads. Instead, U. S. and Canadian railroads implemented a version proposed by William F. Allen, the editor of the Traveler's Official Railway Guide.
The borders of its time zones ran through railroad stations in major cities. For example, the border between its Eastern and Central time zones ran through Detroit, Pittsburgh and Charleston, it was inaugurated on Sunday, November 18, 1883 called "The Day of Two Noons", when each railroad station clock was reset as standard-time noon was reached within each time zone. The zones were named Intercolonial, Central and Pacific. Within a year 85% of all cities with populations over 10,000, about 200 cities, were using standard time. A notable exception was Detroit which kept local time until 1900 tried Central Standard Time, local mean time, Eastern Standard Time before a May 1915 ordinance settled on EST and was ratified by popular vote in August 1916; the confusion of times came to an end when Standard zone time was formally adopted by the U. S. Congress in the Standard Time Act of March 19, 1918; the first known person to conceive of a worldwide system of time zones was the Italian mathematician
