The Tesla–Edison Feud. You’ve probably heard about the famous rivalry between Nikola Tesla and Thomas Edison—both giants of electrical engineering whose innovations changed history. But what exactly was their history with one another? That whole boss/employee thing. Tesla, a Serbian by parentage, began working for the phone company in Budapest. In 1882, he headed for Paris, where he took a job with the Continental Edison Company. Clash of the methods. Edison relied heavily on tedious experimentation for most of his discoveries, a commitment which some historians attribute partially to his lack of formal education.

Clash of the lifestyles. Clash of the...similarities? War of Currents! The Bet. The rift. “Post-war” history. Tesla on Edison: "If he had a needle to find in a haystack he would not stop to reason where it was most likely to be, but would proceed at once, with the feverish diligence of a bee, to examine straw after straw until he found the object of his search. ... The Rainmaker:control weather. How to Survive a Plane Crash. <br/><a href=" US News</a> | <a href=" Business News</a> Copy The harrowing Asiana Airlines crash at San Francisco International Airport may incite fear in the minds of the millions of Americans who take to the skies every year, but it also proves that even horrific disasters are survivable.

The San Francisco-bound flight was carrying more than 300 people Saturday when crashed on the runway, tore its tail and burst into flames. Two 16-year-old female students from China were killed, and 181 people were injured in the crash. The injured were being cared for at several hospitals, and at least 22 were in critical condition. San Francisco Plane Crash: 2 Killed in Asiana Crash Were Teenage Girls on School Trip from China While only one in 1.2 million flights end up in an accident, according to the National Transportation Safety Board, there are still precautions passengers can take to prepare for emergency situations.

The cost of pregnancy in America. I now live in a bigger city, and I'm in Canada, so yes, I was being hyperbolic. But when I was growing up, I was in an isolated community, and we had one hospital. The next town was a two-hour drive away, and there was only one small hospital there as well. The next town of any significant size was another hour past that, and they had one moderately sized hospital. The city, where live now, was an hour and a half ferry ride past that, and there are a couple hospitals here. The problem with a market-driven healthcare system is that they don't see people as the clients, but rather as the product. And then there's the fact that some insurance plans have contracts with certain hospitals, and it gets even more messy. Here in Canada we have a system that works very well for necessities. Competition works very well in some fields, but not in medicine.

Free State Wordpress website. If you’re reading this on the Now I Know website (that is, not in your email inbox), you’re on a website which runs a piece of software called WordPress. WordPress is a very popular blogging software; according to Forbes, as of September of last year, there were more than 60 million websites running WordPress, and the vast, vast majority of those users paid $0 for the privilege. WordPress is free. (The company which makes it, Automattic, also provides a paid-for enterprise version, but it’s rare to see someone using it.) Further, WordPress is open-source and Automattic encourages developers and designers to create software and themes which work with WordPress. In the decade since WordPress’s initial release, a robust community has sprouted around it. For many people and institutions alike, WordPress is a great way to save money on a website. Well, that’s not good. And as it turns out, that rather large warning sign shouldn’t have been ignored.

With or without insurance, the U.S. is the most expensive place to give birth in the world . At the same time, America has one of the highest rates of infant and maternal death among developed nations. Maybe it's time to consider how a few other countries approach childbirth. 1. The Netherlands Except in high-risk cases, women in the Netherlands turn to midwives, not obstetricians, during their pregnancies. The Dutch healthcare system includes universal coverage with the option of additional private plans. 2. Pamela Druckerman's 2012 book Bringing Up Bébé made thousands of moms want to relocate. 3. Midwives call the shots in Deutschland. But here's something that'll really make you cry—with joy or outrage, depending on where you live.

It's not uncommon for pregnancy to be treated as a career liability, even in countries that outlaw such discrimination. 4. 5. Weirdest Urban Ecosystems. Hong Kong has an astounding number of pedestrian walkways and passages mainly in three areas: Central/Admiralty, Tsim Sha Tsui and Wan Chai/Causeway Bay. These are combinations of MTR (subway) stations, building lobbies, above street level passage ways and escalators, underground passage ways, malls and shops. You can literally walk for miles without having to cross a street at ground level. This system offers protection from the monsoon rains and from the harsh subtropical sun, as well as keeping us away from traffic.

Many part are air conditioned which helps during the long summer. A book was recently released with maps like the one below. SExpand Walkways range from the modern to the post-modern.

Nuove sette meraviglie del mondo. Da Wikipedia, l'enciclopedia libera. Le nuove sette meraviglie del mondo sono sette opere architettoniche che idealmente richiamano l'antico elenco canonico delle sette meraviglie del mondo (risalente al III secolo a.C.).

L'iniziativa non è in alcun modo legata all'UNESCO. Storia[modifica | modifica sorgente] Durante i Giochi della XXVII Olimpiade, svoltisi nel 2000 a Sydney, lo svizzero-canadese Bernard Weber lanciò un referendum mondiale via internet per determinare le "Nuove sette meraviglie del mondo" fra 17 opere architettoniche. L'iniziativa raccolse ben presto un enorme successo. La lista delle 17 opere candidate - in seguito a notevoli pressioni delle opinioni pubbliche dei Paesi di tutto il mondo - aumentò fino a superare il numero di 150, mentre la chiusura del sondaggio venne ripetutamente posticipata. A partire dal 2004, i voti sono potuti pervenire anche via telefono o (in alcuni Paesi) via SMS. Le sette meraviglie del mondo moderno[modifica | modifica sorgente] Petra and the Nabataeans.

This Bible History Daily article was originally published in 2012. It has been updated. —Ed. Who were the Nabataeans? The Siq is a tortuous half-mile-long canyon that winds its way from the entrance of Petra to the large open plaza at the foot of the Khazneh. Formed through countless millennia of geological activity and water action, the canyon was used by the Nabataeans as a ceremonial route into their capital. The sides of the Siq were also outfitted with channels and pipes that carried fresh water into the city. For every tourist who visits the ancient city of Petra in modern-day Jordan, there is one breathtaking moment that captures all of the grandeur and mystery of this city carved in stone. The façade, popularly known as the Khazneh, or “Treasury,” appears first only as a faint vision, its architectural details and full dimensions crowded out by the darkened walls of the Siq. The Khazneh is both unexpectedly familiar, and at the same time, strangely exotic.

Glenn J. The Walled City. L'Isola delle Rose: tra utopia e opportunismo. C’è chi odia questo periodo, come se per la storia non significasse nulla. Poi c’è chi lo ama ed è invece convinto che la storia, dopo i favolosi anni sessanta, non sia più stata la stessa. Vi voglio parlare di un uomo, di un ingegnere, che non sappiamo da che parte stia: sappiamo però che si chiama Giorgio Rosa e che in quel periodo, in quei favolosi anni sessanta, è sulla bocca di tutti. L’insospettabile Giorgio Rosa nasce a Bologna nel 1925. Nel 1943, appena maggiorenne e quando una scelta non può più essere rimandata, si schiera con i repubblichini. È chiamato al servizio militare e in quei tempi l’alternativa è una soltanto: la clandestinità. Non ci è dato conoscerne le motivazioni ma sappiamo oggi, direttamente dalle sue parole, della delusione che consegue quella scelta. Fatto che porterà Giorgio Rosa a dichiararsi apolitico e a coltivare una certa avversione verso lo Stato Italiano.

Il progetto La Riviera vive il Boom Ma sotto quale voce cataloghiamo questa creazione? La nazione Fonti: Centralia Mine Fire. Centralia, Pennsylvania No one knows exactly how it started, but a coal vein has been burning under the Pennsylvania mining town of Centralia since 1961. Some trace it back to careless trash incineration in an open pit mine igniting a coal vein. The fire crawled, insidiously, along coal-rich deposits far from the miner's pick, venting hot and poisonous gases up into town, through the basements of homes and businesses. With dawning horror, residents came to realize that the fire was not going to be extinguished, or ever burn itself out -- at least not until all the interconnected coal veins in eastern Pennsylvania were spent in some epic, meatless barbecue. As the underground fire worked its way under rows of homes and businesses, the threat of fires, asphyxiation, carbon monoxide poisoning, and long-term health impact became a daily concern.

The government eventually stepped in, and Centralia joined an elite club of communities, including Love Canal and Times Beach. Made in China: European Clone Towns. Taking counterfeiting to a whole new level… Paris in China In the outskirts of Shanghai stands a fake Eiffel Tower overlooking a replica of the Champ de Mars and rows of Parisian townhouses. This is not Disneyland in China, this is the gated community of Tianducheng, built in 2007 by real estate develepors Zhejiang Guangsha Co. Ltd. Rather mysteriously, very little information about the town has been made available since it’s opening in 2007. The last known population of Tianducheng is around 2,000, yet the town can comfortably house over 100,000 people. More than anything, Tianducheng is a popular place for young newlyweds to use for their wedding photography, using the fake Paris as a backdrop.

This is Hallstatt, Austria: And this is it’s Chinese knock-off: A replica of an entire historical Austrian town was unveiled in the Chinese province of Guangdong earlier this year. Hallstatt: Not Hallstatt: Little London in China Photos via here, here, here and here. Thames town and more. By Daily Mail Reporter Published: 11:47 GMT, 6 May 2013 | Updated: 12:15 GMT, 7 May 2013 China is notorious for making knock-off designer clothes and high-end electronics. But this time the country has excelled itself. With its mock Tudor buildings, cobbled streets, red telephone boxes and a Gothic church, this could be a quaint English market town, but bizarre settlement is actually in the People's Republic.

And unlike most places in the UK, its population is shrinking. 'Thames Town', about 19 miles from central Shanghai, is virtually a ghost town.

Where are we? Hallstat chinese copy. Just one year after announcing ambitious plans to copy of a small idyllic Austrian mountain village, Chinese developers have unveiled their clone hamlet.

Located just outside the southeastern city of Huizhou, the new village is a close approximation of Hallstatt, Vienna, complete with rows of pastel-colored chalets, architectural finials, and even an exact replica of the town clock tower that characterize the 900-year old original. Overseen and operated by Minmetals Land Inc., the $940 million project was recently completed, with Halstatt mayor Alexander Scheutz on hand to open the complex to tourists this past Saturday. When news of the project spread last summer, Hallstatt residents expressed outrage at the idea of the Chinese fake, threatening to make an appeal to UNESCO to potentially halt the building. The town soon came around, however, after realizing the great promotional opportunity the Chinese development presented.

ENGLISH VERSION: Gunkanjima: the ghost island L'isola di Hashima, sperduta tra le 505 isole disabitate della prefettura di Nagasaki, in Giappone, è un luogo spettrale e affascinante, meta di un insolito turismo avventuroso e alternativo. L'isola è chiamata anche Gunkanjima, che significa "nave da guerra", per via dell'aspetto che assume il suo profilo sul letto dell'Oceano: un'isola grigia e decadente, circondata da un grande muro di cemento e i cui edifici prossimi al collasso vanno a delineare la forma di una specie di grande nave da guerra.

Questa misteriosa isola fu costruita sopra un'importante miniera di carbone (di proprietà della Mitsubishi) che, nel periodo compreso tra il 1887 ed il 1974, contribuiva notevolmente a rifornire di energia la città di Nagasaki, che si trovava ad un'ora di navigazione. Nel periodo di massima attività l'isola produceva 410.000 tonnellate di carbone all'anno, una produzione intensa che andava però a discapito della vita umana.

Fa parte delle isole Yaeyama e misura appena 29 km quadrati. Durante l'ultima era glaciale era unita al continente da un piccolo lembo di terra emersa ma, in seguito all'innalzamento dei livelli del mare, finì per diventare un'isola. Il nome Yonaguni ha cominciato a fare il giro del Globo in seguito ad una scoperta sensazionale che, se si rivelasse davvero per quello che sembra, allora bisognerebbe riscrivere la storia dell'intera umanità... Le acque che circondano l'isola sono una nota meta turistica per le immersioni, grazie soprattutto ad una numerosa popolazione di squali martello.

E' stato proprio durante una di queste immersioni che, nel 1987, Kihachiro Aratake notò delle strane formazioni sul fondale marino simili a grandi strutture architettoniche.
