KidZania provides children and their parents a safe, unique, and very realistic educational environment that allows kids between the ages of four to twelve to do what comes naturally to them: role-playing by mimicking traditionally adult activities. As in the real world, children perform “jobs” and are either paid for their work (as a fireman, doctor, police officer, journalist, shopkeeper, etc.) or pay to shop or to be entertained. The indoor theme park is a city built to scale for children, complete with buildings, paved streets, vehicles, a functioning economy, and recognizable destinations in the form of “establishments” sponsored and branded by leading multi-national and local brands.

Inspired by high school architecture class where he was assigned to create simple paper models using cut paper manilla folders, San Francisco-based designer Luca Iaconi-Stewart went home to begin construction on an extremely ambitious project: a 1:60 scale reproduction of a Boeing 777 using some of the techniques he learned in class. That was in 2008, when Iaconi-Stewart was just a junior in high school.

Like a scene from a fantasy movie, a dilapidated room that appears to have been literally ripped out of a building remains suspended in mid air above Nantes, France. Its walls were torn apart, revealing bricks below the plaster, and wood floors reveal the joists inside. The floating room is accessible via a ladder. The gravity defying surreal installation is the work of Argentinean artist Leandro Erlich. The large-scale piece, called “Monte-meubles – L’ultime déménagement” (literally - The Furniture Lift – The Ultimate Moving Out), was created for the biannual Le Voyage a Nantes, an art festival which turns the entire French city into an art gallery.

Macro or Micro? Scientists’ pictures baffle our sense of scale. It began when Stephen Young, a geography professor at Salem State University in Massachusetts, tricked his biologist colleague Paul Kelly into thinking a satellite image was one of his electron microscope scans. Can you guess whether they are close-up or very far away? (Photo by Paul Kelly)

“The Chernobyl disaster was a catastrophic nuclear accident that occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in Ukrainian SSR, which was under the direct jurisdiction of the central authorities in Moscow. An explosion and fire released large quantities of radioactive contamination into the atmosphere, which spread over much of Western USSR and Europe. It is widely considered to have been the worst nuclear power plant accident in history, and is one of only two classified as a level 7 event on the International Nuclear Event Scale (the other being the Fukushima Daiichi nuclear disaster)”. – Wikipedia (Photos by Alexandr Strannik, August 1986; Source: LiveJournal)

Visitors to Salisbury Cathedral stop to look at Sean Henry's sculpture Standing Man (2007) currently being exhibited in the Cloisters on August 2, 2011 in Salisbury, United Kingdom. The exhibition, “Conflux: A Union of the Sacred and the Anonymous”, features over 20 contemporary sculptures of dramatically different scales occupying vacant plinths and open spaces on both the inside and exterior of the iconic 13th century building. This exhibition brings to the Cathedral the biggest single group of polychrome sculpture since the Reformation and runs until the end of October. (Photo by Matt Cardy/Getty Images)
