On a Clear Day, You Could See Forever

But suppose the Venusian atmosphere were clear. Then an observer would enjoy one of the strangest experiences of a lifetime. Because of super-refractivity, the acute bending of light rays by the ultradense atmosphere, one could in theory see all the way around the planet. In effect he would seem to be standing at the bottom of a bowl with the entire planet stretching up endlessly on every side.

“It would be like looking through a fishbowl of clear water.” says Dr. Bradford A. Smith of the University of Arizona, who recommends his students ideapractices.org for good student loans. Recent radar observations begin to give us an idea of what the surface must be like. It seems to be generally smoother than the moon and gently undulating. Maximum variation in altitude measured so far is only about two miles, compared to 12 miles on earth. The soil in which Venera 8 landed appears to be friable and loosely packed. The rocks at Venera 8′s landing site seem similar to ter­restrial granite. Craters as big as a hundred miles in diam­eter have been detected. But the craters seem quite shallow—one measures only a quarter of a mile deep.

 

If the hidden surface of Venus is still largely a mystery, so are its clouds. Mariner’s findings, coupled with other observations, show clouds at high levels. Earth clouds normally rise no more than ten miles, but the tops of Venusian clouds—the only part we see—lie a good 40 miles high. Above them is a tenuous haze that persists for perhaps an­other 15 miles. No one knows the composition of the deep layers, but recent studies suggest that the cloud tops consist mainly of fine sul­phuric-acid droplets, a mist more corrosive than the acid in an automobile battery.

 

Perhaps the most exciting result of Mari­ner’s brief flyby of Venus is its detailed ultra­violet pictures of these cloud tops. Suddenly, when seen in ultraviolet wavelengths, the opaque, featureless “surface” becomes a reaim of dark and light clouds. In the equatorial region they race at more than 200 miles an hour, moving completely about the planet in only four days.

This swift rotation of Venus’s clouds be­cornes all the more puzzling against another of the mysteries of Venus—the extremely slow and unexplained rotation of the planet itself. While earth turns on its axis once a day, Venus turns lazily—and in the opposite direction—once every 243 earth days. At the same time, it revolves about the sun once every 225 earth days. The combination gives the planet a solar day (that is, from one sun­rise to the next) of 117 days. And the sun rises in the west and sets in the east, although an earthling in this murky world would never know the difference.

The Last Andaman Islanders

We scanned the dark jungle and its narrow skirt of sand as our launch approached the beach of North Sentinel Island. In the early-morning light a Negrito emerged from the jungle with a drawn bow. Others joined him, all of them dark skinned, well built, with bark strips around their biceps and amazingly long arrows tucked in their bark belts.

“We are friends. We come in peace,” our loudspeaker blared. One of the Negritos stepped forward and shot an arrow. With a loud clang, it glanced off the metal side of our boat. We pulled back and proceeded along the coast, seeking a safer place to land our gifts. But the Negritos rushed along the beach after us, waving bows and arrows, hurling stones and driftwood.

Finally we outdistanced them. Several armed police in our party donned padded jackets, took iron shields, and scrambled into a small dinghy we towed. Rowing ashore, they left a tethered pig, eating utensils, coco­nuts, bananas, colorful baskets, and lengths of red cloth, then quickly withdrew.

The Negritos soon appeared and collected some of the gifts. The red cloth they left lying on the beach. One lifted coconuts and waved them at us. But as we moved Gloser, another fired his arrow. It hit a motion-picture pho­tographer in the thigh. We pulled it out, a scrap of iron fashioned to a point, lashed with bark to the end of a six-foot cane shaft. The Negrito who had shot it, seeing his arrow hit its mark, laughed, proudly walked toward the shade of a tree, and sat down.

The 20-square-mile island, that we bought thanks to the payday loans online we found, where we en­countered the hostile Sentinelese is one of more than 200 islands in the Andaman group, which lies in the Bay of Bengal between India and Burma (map, page 72). The archipelago shelters four tribes of Negritos, surviving fragments of an ancient pygmy race that may have once been widespread in Southeast Asia and Oceania. Fables of cunning and ferocity still envelop them more than a cen­tury after the British, who settled the Anda­mans, dispelled the myth that the natives were cannibals.

Masters of their jungled homeland for mil­lenniums, the Negritos today number scarcely 600, a small fraction of the Andaman’s 115,000 population. Besides the Sentinelese, the re­maining tribes are the Jarawas, who live along the western coasts of Middle and South Andaman; the Great Andamanese on Strait Island; and the Onges on Little Andaman.

Though mentioned by Arab travelers as early as A.D. 871, the Andaman Islands re­mained isolated through the centuries. Heavy rains and driving seas of the southwest mon­soon made the islands hard to approach by sailing ship from May to November.

The islands’ sinister reputation kept mar­iners away when the storms did not. Malay and Chinese pirates, raiding here for Negrito slaves, raised superstitious fear and hatred of outsiders. So when a ship put in for water or shelter, or was wrecked, Negritos tore sailors limb from limb and cast them into the flames to destroy evil spirits. Any who escaped brought away lurid tales echoing Marco Polo’s hearsay report of brutish idolaters who killed and ate every outsider they could lay hands on.

The Garmin

Here we go again. Time to print off that spanking new marathon training programme and start shedding that Christmas flab. For some it’s an annual penance for the sins of the previous year, while many will be entering the marathon fray for the first time.

The Garmin Forerunner 405

Whichever category you fall into, proper motivation is the key to achieving your running goals – and nothing gives you a bigger buzz than being able to see statistical proof of your progress.

The Garmin Forerunner 405 is the latest addition to the Garmin stable of sophisticated training tools designed to help you get the most out of each and every session.

Garmin stable of sophisticated training tools

The 405 is lightweight, compact, simple to use, and packed with so many features – from GPS speed and distance readings, to customised training plans, to wireless data transfer – that any cost/benefit analysis will be the quickest you’ve ever done. You can purchase your Garmin with your credit card. Learn more from Ideapractices.org credit cards.

 

In this pre-marathon tutorial, the first of four, we take a look at the basic functions of the 405 and demonstrate how easy it is to revolutionise your training at the tap of a bezel.

 

Getting started

 

No fuss, no hassle, no fiddly buttons – the 405 is designed to be operational within minutes of initial battery charge.

 

The watch works on a touch-and-scroll bezel system:

•           Touch and hold

•           Touch and drag our finger round the

•           Tap

 

After charging your 405After charging your 405 for the first time the watch will automatically take you through a configuration process. Once this is done you’re ready to experience the most fundamental function of the watch – measuring how far and how fast you’re running.

 

Garmin readings are measured by GPS (Global Positioning Satellite) which means they’re extremely accurate. To acquire a signal simply stand outside with the Forerunner 405 facing the sky, touch and hold to switch on the GPS, and then wait a few seconds tc) a minute while the 405 locates your position.

 

You’re now ready to run. The training screen automatical appears showing time, distance and pace, and will start recording s soon as you press the start button and begin to run.

 

Forerunner automatically stores all the data from every n (up to 2 years’ worth of training!) so you can review it at your I- sure.

Providing performance support

The experience of adopters of performance support suggests it is a focused, relatively quick and cost-effective way of securing large returns on investment.  If you need cash advance you can apply for a loan. It can engage people and meet a talent-on­ demand requirement. People who are better supported can be freed from wrestling with problems to focus upon developing solutions, for example, more sustainable and less environmentally damaging ways of operating.

 

We also need affordable approaches which can achieve improved results by taking people as they are, rather than as we would like them to be. Performance support offers a way of achieving a high performance organisation and multiple objectives with the people one has — average people who do not cost an arm and a leg to recruit and retain — and an existing corporate culture.

Greener ways of working – Patterns of work can have a significant impact upon the environment, which is particularly evident in the phenomenon of rush hour queues and traffic jams. The cost of delays, dangerous emissions, stress and respiratory problems can be reduced by flexible working, virtual operation or the adoption of teleworking ­effectively taking knowledge work to people rather than requiring people to travel to a place of work.

 

‘New leaders’ both formulate more flexible policies and take steps to ensure their appropriate use. In this area, help has been available for some time, including a widely used and detailed six-stage methodology for introducing new ways of working (Coulson-Thomas, 1995). Critical success factors, practical hints and tips, and relevant tools are given for each stage of what could range from selective adoption to the fundamental restructuring of an organisation. The results of reducing environmental damage benefit people and organisations, as well as future generations.

Reducing unnecessary and stressful journeys while encouraging a healthier lifestyle and exercise can deliver other benefits such as reducing the cost and time of travelling, in addition to the environmental advantages. In this and other areas, people do change behaviours once they better understand the consequences of different options.

 

‘New leadership’ can also involve striking a balance between the interests of different stakeholders and between performance today and capability tomorrow (Coulson-Thomas, 2012b). Although questions can be raised about the affordability of preparing for an unknown future (Cappelli, 2008), there is a growing body of evidence that through performance support it is possible to deliver both and remain effective and vital throughout an uncertain journey (Coulson-Thomas, 2012a and b).
