Solar Dynamics Observatory Launch, Feb 11, 2010 HD VERSION A sun dog is a prismatic bright spot in the sky caused by sun shining through ice crystals. The Atlas V rocket exceeded the speed of sound in this layer of ice crystals, making the shock wave visible from the ground. The announcer can be heard in the video saying, "The vehicle is now supersonic."

Wireless Parking San Francisco

What if sensors on the street knew exactly which parking spots were free? Your phone could direct you straight to a free space and the city could use that real-time information for dynamic meter pricing, discouraging driving when car traffic is too high. San Francisco is already trying the idea. If it works, it'll be good for motorists, for the city, and for the environment.

Will Hot Water freeze faster than Cold Water? These test experiments were done outside the laboratory and in the real time of -15 degrees below zero. The water must be thrown up, as the cold air easily surrounds the drops and freezes them. 

Rebuilding The World Trade Center

On the morning of September 11th, 2001, two commercial jet planes struck the Twin Towers, causing their collapse and the destruction of the four other WTC buildings. The attack killed 2,750 people at the Trade Center, many of them emergency responders. The collapse of 7 WTC, which had already been evacuated, followed at 5:20 p.m. that day.

The new 7 World Trade Center is the first office tower at the site to be rebuilt. According to architect David Childs, it “serves as the gateway to the World Trade Center and Lower Manhattan...and sets a new standard of commercial building design and construction in New York and across the country.” Opened on May 23rd, 2006, the 52-story building is taller and narrower than its predecessor, and is the first certified “green” building to be constructed in New York City.

Across Vesey Street, Childs’ innovative designs appear again at the Freedom Tower, which the Port Authority began building in April 2006. The tower marks the 1,362- and 1,368-feet heights of the original towers with a metal and glass parapet, and will rise to 1,776 feet with its illuminated antenna.

The Freedom Tower already is the most famous element of architect Daniel Libeskind’s WTC Master Plan. That scheme, finalized in 2003, proposed a descending spiral of towers beginning at the site’s northwest corner and ending at the National 9/11 Memorial and Museum, where the Twin Towers’ footprints will be memorialized.

Designs for the remaining WTC Towers Two, Three, and Four were unveiled in September 2006 at 7 World Trade Center. To create individually distinct towers that fit within the Master Plan, Silverstein brought together an unprecedented group of architectural talent: Norman Foster, Richard Rogers, and Fumihiko Maki. A fifth office tower on Liberty Street, the Santiago Calatrava–designed WTC Transportation Hub, performing arts center, memorial and museum will complete the vision for the site.

After several years of insurance disputes and construction negotiations, Silverstein Properties and the Port Authority are now moving forward with full steam to open all of the new WTC skyscrapers by 2012. The Port also is building a new “east bathtub” like that of the original west bathtub, where Towers Two, Three, and Four and the Transportation Hub will rise—a project that alone requires a full year of construction.

The redeveloped WTC site, including the reduced footprint of 7 WTC, will restore Greenwich Street through the site, reuniting the Financial District with Tribeca and supporting the renaissance of Lower Manhattan. In this respect, the new WTC fulfills those ideals set forth by the Downtown-Lower Manhattan Development Association at the site’s conception nearly 50 years ago.

Everything in the universe is traveling through space-time at the speed of light - the maximum speed possible. If you are sitting still in space, then you are traveling through time at the maximum speed. But if you begin traveling through space, then your progress through time slows down.
