The model describes the layout of a city. It says that even though a city may have began with a Central business district, or CBD, other smaller CBD's develop on the outskirts of the city near the more valuable housing areas to allow shorter commutes from the outskirts of the city. This creates nodes or nuclei in other parts of the city besides the CBD thus the name multiple nuclei model.
As multiple nuclei's develop transportation hubs such as airports are constructed, these transportation hubs allow industries to be constructed with cheap transportation costs. These Transportation Hubs can also create noise pollution and lower land values so land becomes cheap. Hotels are also constructed near airports because people who travel tend to want to stay closeby to the airport or source of travel. Housing develops in wedges and gets more expensive the farther from the CBD. (Swanson 360-364)

This increase of movement allows for the specialization of regional centers (e.g. heavy industry, business park, Retail Areas). The model is suitable for the big and expanding cities.

Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.
Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !
