Understanding the greatest buildings of the world

 

 

Your world is filled with structures that have stood the test of time. That give character to the cities and landscapes in which they’re located. That are visited by millions of people each year. And that capture our wonder for the marvels of engineering innovation and progress.

But while structures such as the Giza pyramids, Brunelleschi’s dome, and the Brooklyn Bridge are visual spectacles in and of themselves, they are just as important for the way they were designed as for the way they look. These and other structural masterpieces were, first and foremost, novel creations born from the most progressive engineering concepts and tools of their day. They represent uniquely effective solutions to perplexing structural concerns. And they serve as landmark moments in the millennia-long history
of engineering.

Now, experience the engineering genius that makes these works possible with Understanding the World’s Greatest Structures: Science and Innovation from Antiquity to Modernity—a marvelous learning experience that takes you around the world and reveals the stories behind the most famous bridges, churches, skyscrapers, towers, and other structures from thousands of years of history.

They’re always going somewhere just past those towers, always somewhere in a hurry – and always there were; they could not see, did not notice; these are the same people.

Here clearly can see two lines in the life of mankind. One is the life of all the people below; the other is the life line of those who built Notre Dame. Looking down from these towers you feel that the real history of mankind, worthy of mention, and there is a story of the builders of Notre Dame, and not those who pass by. And you realize that these two stories are incompatible. Continue reading
