Ecological Homeostasis

Are We Short of Water and Food ??

http://www.lovinghut.com/
Since the vegetarian diet is the most effective solution to global warming, under Supreme Master Ching Hai's guidance, members of The Supreme Master Ching Hai International Association recently opened a chain of Loving Hut vegetarian restaurants around the world, in the United States, Japan, Indonesia, Au Lac and Formosa. These places provide affordable and high-quality vegetarian delicacies to the public, bringing a positive impact on the food and beverage industry...
Meat or vegetables? Independent online (SA)
A recent study has revealed that giving up meat could drastically reduce one's carbon footprint. A diet with meat is responsible for producing in a year (as many) greenhouse gases as driving a mid-sized car for 4,758 km, the Institute for Ecological Economy Research (IOeW) said last week. But the food a vegetarian consumes in (the same period of time) is responsible for generating (gases only) as driving for 2,427km, the IOeW said in a study commissioned by independent consumer protection group Foodwatch...
Vegetarian Shoes And Bags
The term pleather ("plastic leather") is a slang term for synthetic leather made out of plastic, a portmanteau of plastic and leather, the term can be either descriptive, or derogatory, depending upon the user (the derogatory use implies use as a substitute for genuine animal hide leather to cut costs)...

  • Galactic Highway - The Wormhole

    • Wormholes are a valid consequence of Einstein's general relativity view on the universe. A wormhole, in theory, acts as a shortcut or tunnel through space and time. There are several versions on the same theme (i.e. wormholes may link different universes; they may link the two separate locations in the same universe; they may even link black and white holes together), but the physics is similar, wormholes create a link two locations in space-time, bypassing normal three dimensional travel through space. Also, it is theorized, that matter can travel through some wormholes fuelling sci-fi stories like in the film Stargate or Star Trek: Deep Space Nine.

    If wormholes do exist however, it is highly unlikely that you'll find a handy key to open the mouth of a wormhole in your back yard, they are likely to be very elusive and you'll probably need some specialist equipment to travel through them (although this will be virtually impossible).

    Alexander Shatskiy, from the Lebedev Physical Institute in Moscow, has an idea how these wormholes may be observed. For a start, they can be distinguished from black holes, as wormhole mouths do not have an event horizon.

    Secondly, if matter could possibly travel through wormholes, light certainly can, but the light emitted will have a characteristic angular intensity distribution. If we were viewing a wormhole's mouth, we would be witness to a circle, resembling a bubble, with intense light radiating from the inside "rim". Looking toward the center, we would notice the light sharply dim. At the center we would notice no light, but we would see right through the mouth of the wormhole and see stars (from our side of the universe) shining straight through.

  • Stream of Time

    • Plato argued that time is constant - it's life that's the illusion. Galileo shrugged over the philosophy of time and figured out how to plot it on a graph so he could get on with the important physics.

    Albert Einstein said that time is just another dimension, a fourth one to go along with the up-down, side-side, forward-back we move through every day. Our understanding of time, Einstein said, is based on its relationship to our environment.

    Weirdly, the faster you travel, the slower time moves. (Is it truely weird? Not quite!!) The most radical interpretation of his theory: Past, present, and future are merely figments of our imagination, constructs built by our brains so that everything doesn't seem to happen at once.

The Perfect Score: 2008 Summer Olympics

A 10 Isn't Necessarily Perfect in New Scoring System for Gymnastics By JULIET MACUR

In one of the most memorable moments in Olympic history, the American gymnast Mary Lou Retton received a perfect 10.0 on her vault at the 1984 Los Angeles Games to clinch the all-around title.

No gymnast will repeat that feat at the Beijing Games, guaranteed.

The gymnastics scoring system based on a top mark of 10.0 will not exist at these Olympics. The system, which had been in use for about 80 years, was replaced two years ago with one that has no ceiling.

Some gymnastics purists, including Retton and her former coach, Bela Karolyi, are still mourning.....

Spurred in part by the judging errors at the 2004 Olympics, the international gymnastics federation, known as the F.I.G., changed the system to better differentiate one gymnast's routines from another's.

Gymnasts now receive separate marks for degree of difficulty and for execution in each event. The two are added to obtain the overall score, which usually ranges from 14 to 17 for top-level gymnasts.
....

The new system is heavy on math and employs two sets of judges, an A panel and a B panel, to do the computations. Two A-panel judges determine the difficulty and technical content of each routine. Six B-panel judges score routines for execution, artistry, composition and technique.

The A-panel judges'scorecards start at zero, and points are added to give credit for requirements, individual skills and skills performed in succession.

The A panel counts only the gymnast's 10 most difficult skills, which are ranked from easiest to most difficult (from A to G for women and from A to F for men). An A-level skill, like a back handspring in the floor exercise, is worth one-tenth of a point. The value increases by one-tenth of a point for each subsequent level, meaning a B-level skill is worth two-tenths and an F-level is worth six-tenths.

Required elements add a maximum 2.5 points to the score. Extra points, either one-tenth or two-tenths, are given for stringing skills together.
....

Nastia Liukin of the United States team, for example, performs a routine on the uneven bars that has a sky-high difficulty value of 7.7. Her father and coach, Valeri Liukin, crunched numbers last year to invent the complex, high-scoring routine.

He did the calculations on a Post-it before handing it to his daughter at practice one day. She gasped.

"I was like: Wow, you want me to do all of that? Is that possible?" Nastia Liukin said. "But then I realized that I need to do all that with this new scoring, if I even want to think about a gold medal. I said: OK, cool. I'll learn it."

At the United States championships in May, Liukin nailed her performance and scored a 17.1, the highest score by any gymnast from the United States since the system changed. She said she expected to score even higher at the Olympics.

Liukin could do just that if she is able to pull off the routine, which is filled with risky skills. At her best, Liukin seems as if she is weightless as she floats above and between the bars.
