The Port Authority of New York and New Jersey released this dizziness-inducing video of construction workers installing the final section of spire atop One World Trade Center. Some seriously brave ironworkers erected the final piece of the building on May 10.
“Using a crane located high above street level, ironworkers lifted the final two pieces off a temporary work platform on the roof of One WTC and attached them to the previously installed 16 sections of spire,” the authority wrote on its Youtube post. “During the installation, ironworkers set and tightened 60 bolts at an altitude of 1,701 feet in the air.”
They report the building now stands at 1,776 feet high, making it the tallest building in the Western Hemisphere and the third tallest in the world. Huzzah, engineering!

MIT video analysis experts have developed a new way to amplify subtle shifts in color and motion that are normally invisible to the naked eye.
The result of their work: video that could be used to accurately detect pulse rate based on the human face’s rhythmic flush, monitor babies’ breathing or study the movements of buildings, cranes and mechanical devices.
“You can think about what we’ve made like a microscope, except for video,” says doctoral student Michael Rubinstein, whose team came up with the now patented analytical process they call Eulerian video magnification. “It’s a tool to amplify small spatio-temporal variations you can’t normally see.”
