Travnik se trouve dans la vallée de la rivière Lasva, et est entourée par la montagne Vlasic au Nord et Vilenica au sud.
Les premières traces historiques datent de 1244, quand le roi hongrois Bela IV donna à ses notables un bout de territoire près de la rivière. A cette époque, la zone était un fief de l'état bosnien.
Bien que les restes de cette époque ne montrent pas la richesse que la vallée a connu à l'époque romaine, il y avait un nombre impressionant de chateaux et de propriétés. La forteresse de Travnik était la plus impressionante à l'époque, et est toujours la mieux préservée.
L'époque ottomane renouvela la gloire de Travnik. Ce fut le principal centre urbain et militaire de l'Empire Ottoman, duquel étaient lancées les invasions vers le sud-ouest. Les ottomans amenèrent les mosquées, les madresa, les routes et les systèmes hydrauliques. Ils fortifièrent la forteresse médiévale et construirent une mini-cité à l'intérieure de ses épais murs. Pour plus de 150 ans, le vizir de Bosnie eut son siège à Travnik, attirant à la fois des consulats et des commerces. Les voyageurs visitant Travnik à l'époque furent impressionnés par celle-ci et l'appelèrent "l'Istanbul européenne". Elle était considérée comme la ville la plus orientale en Bosnie. Le brillant livre d'Ivo Andric, "les chroniques de Travnik", permet d'avoir un aperçu de la période.

Travnik is situated in the valley of the Lasva River and bordered by Vlasic Mountain to the north and Mount Vilenica to the south.
The valley appeared in 1244, in terms of primary historical records, when the Hungarian King Bela IV gave one of his notables a piece of land in Lasva. By that time, the area was a feudal estate of the Bosnian state.
Although remains from these centuries do not show the wealth the valley had known in Roman times, the era did have its share of castles and mansions. The Travnik Fortress was the most impressive fortress at the time, and still stands out as the best preserved of them all. This era gave Travnik its name.
The Ottoman era renewed the glory of Travnik. It was the principal city and military centre of the Ottoman Empire. It was from here that the Ottomans planed their invasions further towards the southwest. They brought mosques, religious schools, roads and water systems. They fortified the medieval fortress and built a mini-city within its high stone walls. For over 150 years, the vizier – the Ottoman Sultan's representative in Bosnia - had his headquarters in this town, attracting both consulates and trade. Travelers visiting Travnik in this era were impressed by the town and called it the European Istanbul and the most oriental town in Bosnia. Ivo Andrić's brilliant 'Travnik Chronicle' gives you a feel of this period.

SHANGHAI: A History in Photographs, 1842-Today

Shanghai traces the story of the most modern of China’s cities, through evocative, beautiful and sometimes painful images. In 1842, the signing of the ignominious Treaty of Nanking turned a small riverside stop-off into a bustling treaty port. Over the near-170 years that followed, Shanghai was shaped and defined by outside forces, from the foreign concessions and Japanese occupiers through to the arrival of the Communists and the cult of Mao. Through civil war, invasion, revolution and famine, Shanghai beat the odds to become a thriving metropolis that commands a place in the contemporary imagination unlike any other. Shanghai has unceasingly been a byword for style, culture, business, and opportunity, and has led the way in China’s ongoing economic boom. The story told through the pages of Shanghai is both grand in scale, and domestic in tone. Photographs depict families living under the cloud of war, enjoying the fine life accorded by a booming international trade (as much in pictures of the 19th century as today), and suffering the inequalities of poverty. Time moves on and fashions change, but above all else, it is the humanity of the city of Shanghai shines through in this spectacular and sweeping history.
Liu Heung Shing was born in Hong Kong in 1952, and is a photojournalist with a career spanning more than twenty years. In 1992, Liu became the first ethnic Chinese person to win a Pulitzer Prize, sharing it for his coverage of the collapse of the Soviet Union. With international assignments for the Associated Press and Time magazine to his name, Liu is the author of China After Mao (Penguin, 1983) and China: Portrait of a Country (Taschen, 2008).
Karen Smith is a Beijing-based British art historian, specializing in contemporary Chinese art of the post-Mao era. She is the author of Ai Weiwei (Phaodon, 2009) and is currently finishing her forthcoming book, Bang to Boom: Chinese Art in the 1990s.
The history of the forge can be traced back to 1640, and it was still working until around 1910. The industrial site was abandoned in 1929 although the workers’ cottages were occupied until the late 1960s.
Top Forge is a Scheduled Ancient Monument (Grade I) and celebrates the history of iron-working in Britain and especially in South Yorkshire. The Forge is the only surviving water-powered heavy wrought iron forge with its water wheels and hammers (now restored) in situ. It is a site of national importance.
The Industrial Revolution is usually associated with steam power. Wortley Top Forge certainly made its contribution both in the technology of iron making and in supporting the early Railway Age, but only ever used the power of its three water wheels.
The Don valley was an ideal area for iron-making as it had access to ironstone from the Tankersley seam, coppiced timber for charcoal and, of course, water power. Iron has been worked in the valley since the 1300s. Top Forge was built before1640, deliberately in a loop of the river Don in order to shorten the course of the head goyt and to maximise the head of water available between the weir and the tail goyt.
The current layout of the building dates from the 1850s when the forge was turned over to the production of shafts and axles mainly for use on railway wagons. Some of the earliest metallurgical experiments in the world were conducted at the site by the engineer and metallurgist Thomas Andrews.
Railway axles of the highest quality were manufactured at the site in the nineteenth century and exported all over the world.
Axle production ceased at Top Forge by 1910 (the price of mild steel from Sheffield had undercut the cost of wrought iron).
The Top Forge workshops continued to service the works both upstream and downstream until 1929 when all activity ceased.
The older breast-shot water wheel and belly-helve hammer was probably installed in 1680s and would have been almost entirely of wood. As each generation updated this structure, we now have a cast iron wheel with a cast iron axle albeit with evidence of a previous wooden tree trunk shaft.
The larger breast-shot wheel and trip hammer was probably installed around 1840 when railway axle making was introduced. It has been calculated that the four-lobed cam running at 20 revolutions per minute would have a power output of about 8 HP and each hammer blow about half as effective as a 1 ton drop hammer.
The forge also houses a large collection of early industrial machinery

Part of Ai Weiwei's TRACE exhibit at the Hirshhorn Museum (DC).
Per the Hirshhorn Museum website:
"Ai Weiwei’s monumental installation Trace portrays individuals from around the world whom the artist and various human rights groups consider to be activists, prisoners of conscience, and advocates of free speech.
Each of these 176 portraits comprises thousands of plastic LEGO® bricks, assembled by hand and laid out on the floor.
The work foregrounds Ai Weiwei’s own experiences of incarceration, interrogation, and surveillance. In 2011, he was detained by the Chinese government for eighty-one days and then prohibited from traveling abroad until 2015."
Per the TRACE website at the Exhibit:
"Shiva Nazar Ahari is an Iranian activist who was arrested in Iran on charges of waging war against God, propagating against the regime, actions against national security, and disrupting the public order.
Ahari is a journalist and human rights activist and a founding member of the 'Committee on Human Rights Reporters', which campaigns against a wide range of human rights violations in Iran.
In 2012, she began serving a four-year prison term, but was released in September 2013.

Tracé de la ligne Phủ Lạng Thương-Lạng Sơn et des prolonguements Hà Nội-Phủ Lạng Thương et Lạng Sơn-Đồng Đăng, dans le context des liaisons avec la Chine; ce tracé est donc celui de la ligne apres sa mise à voie métrique de 1896 à 1902
Route of the Phủ Lạng Thương-Lạng Sơn line and the Hà Nội-Phủ Lạng Thương and Lạng Sơn-Đồng Đăng extensions, in the context of links with China; this route is therefore that of the line after its conversion to metric gauge from 1896 to 1902
Traces of cosmic rays in a spark chamber. Charged particles cause trails of sparks, which can be seen.
Interestingly, I saw the same kind of exhibit in Stockholm a few years ago and it was far more active. But Geneva has 57% higher incidence of cosmic rays. Maybe there are differences in the machines, or I was in Stockholm during a solar maximum.
When travelling the Natchez Trace Parkway through Lewis County, TN, there is a small parking area for a small scenic stop known simply as Fall Hollow. I have uploaded 6 photos describing what you'll see here.
From the parking lot, it's a 100 foot walk along a paved sidewalk to a wooden observation deck. From here, you can see the upper half of the Fall Hollow Waterfall, where you can see the water tumble about 30 feet. There is a second stream right next to it that tumbles just as far and they meet just a few feet below. (See images #2 and #5.) [Side note: To get the view in this picture, I walked around the area below the observation deck. This is not reccomended unless you are very cautious.]
The official paved trail stops here, but in another 5 minutes of steep hiking, there is much more to see. As you leave the overlook, and walk along the top, unless it's dry season you'll see another 30 foot waterfall of side drainage. From here you can make a steep decline to the area below and if you make a left, you get to a small bridge crossing the tiny trickle and look up at this smaller falls. (See photos #3 and #6).
Still at the base but off in the other direction, you see what I think is the best site here. The two streams that we saw merge from the observation deck now free falls 20-25 feet into a small pool below. Behind this is a small grotto where you can walk behind the falls. (See photos 1 and #4.)
