Who though refraction of sunlight would power a low cost lighting revolution? Alfredo Moser’s invention, using an empty two-litre plastic bottle, some water and a black cap on the bottle is changing lives all over the world.
A seething mass of 33000 people crammed into two and a half hectares made Hong Kong’s Kowloon Walled City one of the most densly populated urban jungles ever. The chaotic mass of highrise buildings, alleyways and makeshift staircases had a rich history, but it became a haven for gangsters, prostitutes and all manner of illegal activities after the Second World War when scores of refugees sought solace in the Walled City. Kowloon Walled City enjoyed a strange relationship with Hong Kong, being mostly a sub-culture of it’s own and left mostly to it’s own devices by the British, it became largely Triad controlled in the 50s. It was eventually torn down and replaced with a park in the early nineteen nineties. WSJ has produced a lovely online rich media journal of Kowloon Walled City.
Giant 3D printers are now able to slap up prefab houses as shown by WinSun. Their massive 3D printer can pump out 10 houses in 24 hours, pouring a pre-mixed glass-fibre reinforced concrete onto a substrate. The estimated cost of building the house is around $5000.
Using computer and 3D modeling software, the designs of the building can also take into account additions like insulation materials, plumbing, electrical lining and windows, which can then be easily outfitted once the rest of the structure is solid and standing.
The Du Jiang Yan Irrigation system was and still is a feat of engineering. Built in 256 BC it stopped annual flooding along the banks of the Min river and ensured the fame of Li Bing, the governor of Qin and engineer behind the project.
The irrigation system is incredible and consists of a levee and a channel cut through Mount Yulei which allows the flood water to be discharged to the Chengdu Plain. To cut the channel through Mount Yulei, Li Bing used a little trick – with gunpowder still a distant future invention, he alternately heated and cooled the rock until it cracked in order to carve out the channel. It took eight years! That is persistance.
The main topic of the fragment is to affirm that women who are mothers and wives can be disciples of Jesus – a topic that was hotly debated in early Christianity as celibate virginity increasingly became highly valued,
Here’s an interesting project that spans art and science – mapping out wifi signals with a technique called light painting. It’s fascinating to look at something that is basically seen as a tool (our continued and contiguous connection to the online world) and turn it into art.
Amazing – just 12 years old and Jaysea Devoe is already teaching yoga! It’s great to see such passion in younger yoga practitioners and such a desire to pass down the traditions.
Much like Chinese Physicians prescribing Qi Gong as part of a patient’s treatment, a program is being launched in Boston which prescribes biking to help the health of Bostonians.
Biking is great for general health and wellbeing, with a fair number of studies on the effects of biking on health
Men who cycled at least 25 km per week had less than half the risk of non–fatal and fatal coronary heart disease of those who were not physically active.
Exercise as medicine, or at least, as part of a medical regime is a great idea. In fact, it’s one that China implemented after the Cultural Revolution when, according to B.K. Frantzis in his book “Opening the energy gates of the body”:
China found itself with less than half of its former medical personnel.
To counteract the medical crisis (which some might consider we are now facing in the west), China set up a national program of Tai Chi. Any patients who had health problems caused by poor lifestyle or lack of exercise were prescribed Tai Chi during their medical consultation. At that point, if the patient wanted another doctor’s appointment, they had to go to Tai Chi or Chi Gung every day for three months.
Though that might be a bit extreme, it pays more than just lip service to the importance of exercise for overall health and wellbeing. Chi Gung and Tai Chi are, of course, very gentle forms of exercise, but moving the body around, stretching and getting the blood flowing can ease and help all sorts of aches and pains.
For The West, the prescription of some gentle biking could be just what the doctor ordered!
