The Eight Greatest Engineering Feats of Mankind

Seeing is Believing

[Advance] I tried to word this right, the title, for surely there are many engineering feats, throughout history, the Roman walls in England, and the Greeks Acropolis, in Athens, and the legendary labyrinth, in Crete, and so on and so forth. But these are the ones I've seen, and feel are worthy to be called among the greatest of mankind. Some are ancient, some are contemporary, all are great, and until I see something better, this will remain written in stone in me, and I am not adding the space programs, or moon landing in this overview, or scenario. Man has accomplished a lot, with his blood and sweat,
Perhaps too much blood and sweat went into these feats, but then, that is part of the human race is it not, to be and seek challenges. So here we go:

1--The Panama Canal: The Panama Canal, one of the world's most impressive achievements, with three locks, and a long canal 51-miles long is perhaps the Greatest engineering Feat of Man kind. I visited the site three times, in 2006.

The city of Panama, an old city dates back to 1673 AD (and some structures to 1519 AD: I've seen them all, impressive); it was once burned down (the old city), I walked among its ruins, which is a UNESCO site now; or World Heritage Site.

What is the Panama Canal? It is a 51-mile waterway, linking the Atlantic with the Pacific oceans. That is it, in a nutshell. I saw large and small ships going through the canal. In the 1880s, France tried to build this waterway, fighting yellow fever and malaria, killing 22,000-people. There was a canal treaty in 1903, and in 1904 the Americans took over the building, and accomplished it in 1914 (it only took ten years to build). They purchased the rights for $40-million dollars from France, who had started the project but could not complete it, at which had $375-million dollars invested into the project; and then the USA invested $300-million. Mountains had to be split in two, creating a crack between them, and manmade lakes created. I saw pictures of the ongoing construction, it was breathtaking, the task.

2--The Great Wall of China: I walked on the Great Wall of China, in 1996, it was a haunting experience. Built between 250 BC and 1450 AD, it expands over mountain rangers and across unforeseeable terrain it is spellbinding to walk up and down its wall, knowing it kept the nomad tribes, or better put, the so called barbarians out (or was suppose to). It stretches two-thousand miles across China, and can be seen from outer space. An ancient engineering feet only surpassed (I believe) 500-years later when the Panama Canal was created. You could put six of the pyramids of Egypt into the construction of the Canal, and have leftover debris.

3--The Central Railroad of Peru (completed in 1907): The Central Railroad of Peru the most distinguished in the world (historically); an engineering feat of land and steal where it reached to heights of fifteen-thousand eight hundred and thirty feet (above sea level) to the city of Ticlio, then down to Bone City (La Oroya) and onto Huancavelica: One thousand miles of rail through mountains, across 41-bridges, around 13-zigzags, through 60-tunnels. It goes alongside the Mantaro Rio, in the Mantaro Valley of Peru (as you can see there were many technical engineering difficulties involved in its making). I have not been on this railroad, but I've seen the bridges, and the tunnels they carved and built for this accomplished, while traveling throughout the Andes of Peru, and the Mantaro Valley itself, and been to the Rio.

4--The Pan-American Highway: While in South America, I've been on this highway a dozen times, but while in Bogota, Columbia, I found it was a little different in that those folks who died on the highway, their loved ones planted trees for them, and you see these trees all about. What a kind gesture.

This was no little project, 29,800 miles of highway (the whole system); from beyond Fairbanks, Alaska to Ushuaia, Argentina in South America (with a 54-mile gap in the rainforest). It is the Americas supper highway, it is really too big, and too complex to put into a small paragraph like this, but let me say, it is a tourist haven; perhaps the best way to travel in the Americas besides the jet.

5--The Plateau of Giza: and its Pyramids and Sphinx (Egypt): When I was in Egypt, I took a tour of the Plateau, and of course the three pyramids, and went into the pyramid of Khafra, with its tunnels, and sections, and all. And got a front row tour of the Sphinx, which only a few people get, and very few, it has to be at midnight to get that special tour, and costly (perhaps as much as the trip to Egypt itself), but you get what you pay for, to touch it, and perhaps a little more). The Great Sphinx is north side of the court, in front are temples, ruins. When you see this combination, and all its linking connections, throughout the Plateau, and the connections with the heavens, astronomical associations, it is a gallery of Engineering on a grand scale.

6--The Siberian Railroad: I've only been on what one may call, a small section of it (Perhaps the European Section), for it goes from England to Brussels, Belgium, to Cologne, Germany, and on to Moscow, Russia, and then on to capitol of Mongolia (Ulan Bater), and to Beijing, China. Not sure who gets the credit for building it, perhaps those countries I just mentioned, it is, if anything, a United Nations Achievement, in that it crosses the boarder of so many countries. But the miles involved, for such a trip I just mentioned would take six-days on the train that in itself is an Engineering feat unsurpassed in a railroad.

7--The Alaskan Pipeline: On my way to Barrow, Alaska and during a flight while in Barrow, across its tundra, I saw pipeline, it is massive, and like a long unending snake. It bewilders me how one might have to go out and fix a link, oh well, the week in Barrow, in 1996, was a long week to say the least, and you see nothing in the Arctic but white, no trees, no anything, except, white bears, white this and that, and the pipeline, which looks white after a while also but is perhaps more silver looking. Back in 1968-'69, when I went to San Francisco, many folks were heading up there to work on oil projects, anticipating the pipeline, as if it was a gold rush. I remember quite well, Dan, a friend of mine, back then; his stepbrother's father was heading up there, to work in oilfields.

The 800-mile-long Trans Alaska Pipeline, it started up in 1977, and pumped, successfully transporting over 15-billion barrels of oil since. It crosses three mountain ranges and over 800 rivers and streams; it cost $8-billion to build, and was mostly from privately funds. It took three-years, and two months to build between 1974-1977, I assume the planning stages were complicated, for they had to build seven airfields to accommodate the construction.

8--Borobudur (the Magnificence): A master piece of art, and engineering (assembly): temple, or shrine to Buddha, with 504 Buddha's statues in sitting or standing positions around the shrine. It is wider than the Great Pyramid of Egypt, built on a mound. I went there in 1999, summer and it encircled me, until I got to its peak, Built in the 8th Century, AD. It has two-million blocks of volcanic rock, to the total building structure, the area is 14,165 square meters, with a width of 120 M. With a total weight of 3,500,000 tones. Only about 5000 visitors go there a year it is not one of your regular stops, to say the least, You have to fly into Yogyakarta, central, Java, to get there (from the Midwest, you go to Alaska to Japan, to Guam, to Bali, and a small plane can take you into the city. On the top of the shrine, is a giant Stupa; there is also a calm, about, and around the whole area.

The eight greatest engineering achievements of mankind

Seeing is Believing

[Advance] I have tried to limit this right to the title, because surely there are many technical achievements in the course of history, the Roman walls in England, and the greek Acropolis of Athens, and the legendary labyrinth of Crete, and so on and so on. But these are the ones I have seen and feel are worthy of being called the greatest of mankind. Some are old, some contemporary, all are great, and until something better I will be writing thisStone in me, and I'm not adding the space program, or the moon landing in this overview, or scenario. Much has been done with his blood and sweat;
Perhaps too much blood and sweat went into these services, but then that part of humanity, is to look for and challenges. So here we go:

1 - The Panama Canal: The Panama Canal, one of the most impressive in the world, with three locks and a canal 51 miles long, is perhaps the greatest engineeringArt Of Man feat. I visited the site three times in 2006.

The City of Panama, an ancient city dates from 1673 AD (and some structures to 1519 AD: I've seen them all, awesome), it was once burned (the old town), I walked through the rubble, which was declared by ' UNESCO website, or World Heritage Site.

What is the Panama Canal? This is a 51 miles waterway connecting the Atlantic and Pacific. That is, in a nutshell. I saw the large and small vessels to pass through the channel. In1880 France tried to build this waterway for the fight against yellow fever and malaria, which kills 22,000 people. It 'been a canal treaty in 1903 and in 1904 the Americans throughout the building and finished in 1914 (it lasted only ten years to build). He bought the rights for $ 40 million from France, which began the project, but may not be completed, which had invested $ 375 million in the project, and then the United States has invested $ 300 million. Mountain was to be divided intotwo, creating a rift between them and the reservoirs created. I saw the pictures of the construction in progress, it is breathtaking, the task.

2 - The Great Wall of China: I went to the Great Wall of China, in 1996, has been a disquieting. Between 250 BC and 1450 AD, built on the hill and extended it rangers in unpredictable terrain, it's great to walk up and down the wall, knowing they were nomadic tribes, or rather the so-called barbarians (or was it too) well.It extends two thousand miles across China, and can be seen from space. An old technology base second only to (I think) 500 years later, when the Panama Canal was created. You can put six of the pyramids in Egypt in the construction of the canal, and debris remains.

3 - The Central Railroad of Peru (1907 completed): The Central Railroad of Peru's most important to the world (historically) to steal a technical result of the country and whereat a height of fifteen thousand eight hundred and thirty feet (above sea level) to the city Ticlio reached, then down to the bone City (La Oroya) and Huancavelica: A thousand miles of railroad through the mountains, over 41 bridges at 13 - zig-zag through 60 tunnels. E 'near the Rio Mantaro, in the Mantaro Valley of Peru (as you can see, there are many technical difficulties in the production technique is involved). I have not been on this road, but I see the bridges,and galleries are carved and built this is achieved, while the vehicle was in the Andes of Peru, and the Mantaro Valley itself, and the Rio.

4 - The Pan-American: While in South America, I've been down this road a dozen times, but while in Bogota, Colombia, I thought it was a little 'different than those who died on the road, planted trees for their loved ones them, and you see all of these trees. What kind of a gesture.

This was no smallProject, 29,800 miles from the () the whole system, from) outside Fairbanks, Alaska to Ushuaia, Argentina in South America (with a gap of 54 miles in the rain forest. And North and South America Highway dinner is just too big and too complex to tell in a short paragraph like that, but let me say that it is a paradise for tourists, perhaps the best way to North and South America Travel next to the beam.

5 - The plateau of Giza and the Pyramids and the Sphinx (Egypt): When I was in Egypt, I have a tour of the plateau,and, of course, the three pyramids, and went into the pyramid of Khafre, with its galleries and sections, and all. And taking a tour of the front row of the Sphinx, to have only a few people, and very few, it is midnight, the trip to get a special and expensive (perhaps as much as the trip to Egypt itself), but what you get paid to touch them, and perhaps a little 'more). Great Sphinx and the north side of the courtyard in front of the house are the ruins of the temple. If you use this combination, and all itsCombination of compounds of Plateau, and the connections to the sky, the Astronomical Society, is an art gallery on a large scale.

6 - The Trans-Siberian Railway: I have only what can be called a small part of it was (perhaps it should be the European branch), as it goes from England to Brussels, Belgium, in Cologne, Germany, and Moscow, Russia, and then the capital of Mongolia (Ulan Bater), and Beijing, China. It is not certain that the credit for the constructionPerhaps those countries I just mentioned, is, if anything, a performance by the United Nations, as they crossed the border of so many countries. But the miles are involved, like a trip I would only say six days by train, which is in itself a technological challenge unprecedented in a railroad.

7 - The Alaska Pipeline: On the road to Barrow, Alaska, and during the flight, while in Barrow, on the tundra, vidi, pipeline, is massive, and for how long tail ending. Itconfuses me, as it should go, and a link, and a week in Barrow, in 1996, was a week long, resolve to put it mildly, and you can see, nothing in the Arctic, but white, no tree, no anything except white bears, white this and that, and behavior, see the white after a while ', but it might seem more silver. Back in 1968-'69, when I went to San Francisco, were many people working up on plans for oil, the anticipation of the pipeline, as it would be a gold rush. II still remember well, Dan, a friend of mine at that time, his stepfather's brother was working on the road up there, in oil fields.

The 800 mile long Trans-Alaska Pipeline, began in 1977 and pumped successfully carrying more than 15 billion barrels of oil. You cross three mountain ranges and to build more than 800 rivers and streams, which costs $ 8 billion, and was driven mainly by private funds. It took three years and two months to build between 1974-1977, I participate in the planningwere complicated because they build up to seven airports in order to allow the construction.

) 8 - Borobudur (the glory: a masterpiece of art and technology (installation): temple or shrine of Buddha, with 504 statues of Buddha in sitting or standing up around the shrine. E 'wider than the pyramid of Cheops in Egypt built on a hill. I was there in 1999, during the summer and around me, until I got the top, built in 8th Century AD. It has two million unitsVolcanic rocks, the whole structure of the building, the area of 14,165 square meters, with a width of 120 m. With a total of 3,500,000 tons. Only about 5,000 visitors go one years does not mean that your regular stops at the very least, it should fly in Yogyakarta, the center, Java, to get there (from the Midwest, you go to Alaska to Japan, Guam, Bali and small plane you can take in the city. On the top of the shrine is a huge stupa is also a quiet, over and aroundentire range.
