Having long been a fan of lighter than air ships I find the prospect of a round the world race quite intoxicating. Continue reading “World Sky Race”
The name says it all. Atomic Annihilation, what a more fitting title for a page dedicated to the art of the atomic age. See the atomic powered bombers, the ‘duck and cover’ posters, downwind fallout projections, the very missiles that were to rain vaporizing death in the event of the balloon going up. This is a wonderful collection of cold war inspired artwork and photography that has played a vital role in shaping the very way we think and speak. Enjoy the trip to the past and hope that it truly is behind us.
(The device)… consists of a thin sheet of resin–fiberglass composite, just a few centimeters across, segmented into 32 triangular panels separated by flexible silicone joints. Some of the joints have heat-sensitive actuators that bend 180 degrees when warmed by an electric current, folding the sheet over at that joint. Depending on the program used, the sheet will conduct a series of folds to yield the boat or airplane shape in about 15 seconds. The folding-sheet approach is an extension of the field of computational origami, the mathematical study of how flat objects can be folded into complex, three-dimensional structures.
A clever hack that combines a Mac Classic with a brand spanking new Apple iPad. No, the Mac Classic no longer works after this hack but you have to admit that it’s better than leaving to molder on a closet shelf somewhere.
I’m fascinated by these cameras. They are an entire photo studio in a box. The photographer uses a hood on the back of the camera to compose and focus and image on the ground glass inside the large box. Once the image is set, the camera is made light tight and the film ( photographic printing paper) is placed on the focal plane. An exposure is made and the photographer reaches inside the camera via a light proof sleeve and develops the paper in the chemistry that is contained in the box. the result is a paper negative that can be re-photographed to produce a positive print. So far this is the best collection of these remarkable cameras I’ve ever come across. They are still used in parts of the world where minilabs and digital cameras are rare.
Landing on Mars in May of 2008, the NASA Mars Phoenix Lander worked remarkably well until November of the same year. It sent back hundreds of images and did soil testing that found calcium carbonate and perchlorate. The mission was only supposed to last for three months but like other NASA missions the service life of the lander exceeded expectations and only ended when the winter sun could no longer charge the probes batteries. When the Martian winter had passe it was hoped that the lander might have survived the deadly cold (-87C) and contact could once again be established. However it was not to be. The lander was no longer responding to commands issued from NASA’s Mars Odyssey orbiter as it did a number of passes over the landing site in multiple listening campaigns. Eventually an image was obtained from the HiRISE camera on the Mars Reconnaissance Orbiter the that confirmed the speculation that an estimated 100 pounds of icy buildup has damaged the delicate solar panels.
