Atmospheric Phenomenon in Joshua Tree


Earth's Shadow and Belt of Venus at sunset looking east from Jumbo Rocks in Joshua Tree National Park
Recently I went on an enjoyable Fall camping trip to Joshua Tree Natural Park. While enjoying a hike around sunset I witnessed an interesting lighting effect that was occurring in the sky in the opposite direction of the sunset. This atmospheric phenomenon called "Earth's Shadow" is a dark blue band near the the horizon caused by the shadow of the earth cast on the atmosphere. The pink band above the earth's shadow (blue band) is called the "Belt of Venus" and is caused by backscattering of the red setting sun.

This atmospheric phenomenon often goes unnoticed and only occurs under the right weather conditions and proper viewing point with clear sight to the horizon.

I never look long to find beauty in nature.

Oblivion Sky Tower

Image
A Futuristic Modern Architecture Box (dubbed the Sky Tower) nestled in the surreal setting above the clouds in the (futurist post apocalyptic) movie Oblivion  (2013) written and directed by Joseph Kosinski . The home takes some obvious inspiration from the Stahl House aka Case Study # 22 by Architect Pierre Koenig . The home has some obvious improvements with the the extended helipad over the see through acrylic infinity pool. The foundation of the home is on a unbelievably thin single (steel?) column that seems to be unaffected by the wind throughout the movie. The Director Joseph Kosinski conceived of the sky tower design with early 3D modeling renderings that he made. Joseph Kosinski graduated from Columbia University with a degree in Architecture that explains the strong modern design elements in his work. Kosinski admits that his production design team refined his early ideas into finished reality . The set is a crisp clean design and the frameless glass wall

32 Simple and Basic Design Ideas of Frank Lloyd Wright

Image
I was recently reading an article from the September issue of 1956 House and Home and was astounded to see an interesting FLLW article with tips for the average home builder. As I was reading through the article I was realizing that those tips and advise were still just as pertinent today as it was in 1956. The particular house the article refers to is the Zimmerman house built in Manchester, New Hampshire. The home is part of a series of homes that Wright built known as the Unisonian Homes that were low cost homes for moderate income families. 32 Simple and Basic Design Ideas of Frank Lloyd Wright 1. Stress the Horizontals. (a) Stretch the roof line. (b) Keep the fascia in one straight line except for a good reason. (c) Define a strong middle line. 2. Don't waste a big overhang on the north, and don't feel you must use the same roof pitch on both sides. 3. Keep the roof line low. 4. Don't build a whole wall and punch holes in it for your windows.

Bruce Goff's Ledbetter House

Image
In 1948, Bruce Goff, a renowned Organic Architect, designed and constructed the Ledbetter House in Norman, Oklahoma. One of the most distinctive features of this unique home is its striking carport floating entry, which is supported by steel cables and provides both shelter and aesthetic interest. The Ledbetter House is a stunning example of Goff's Organic Architecture style, which emphasizes the harmonious integration of buildings with their natural surroundings. The house is situated on a wooded site, and Goff incorporated the landscape into the design of the home. The interior of the house features an open floor plan, ample natural light, and stunning views of the surrounding trees. Goff's use of unconventional materials and construction techniques is one of the most notable aspects of the Ledbetter House. He used materials such as steel prefabricated trusses and stones, which were incorporated into the design in creative ways. The ceiling of the home is made of corr
