Hkakabo Razi of Myanmar (Burma)

Hkakabo Razi
Elevation 5,881 metres (19,294 feet)
Location Kachin, Myanmar
Range Himalaya
Coordinates 28°19′59″N, 97°28′00″E
First ascent September 15, 1996


Hkakabo Razi  is Southeast Asia's highest mountain, located in the northern Burmese state of Kachin.
It lies in an outlying subrange of the Greater Himalayan mountain system.The mountain lies on the border tri-point between Burma, China, and India.
The peak is enclosed within Hkakabo Razi National Park. The park is entirely mountainous and is characterized by broad-leaved evergreen rain forest, a sub-tropical temperate zone from 2,438 to 2,743 metres (7,999–8,999 ft), then broad-leaved, semi-deciduous forest and finally needle-leaved evergreen, snow forest. Above 3,353 metres (11,001 ft), the highest forest zone is alpine, different not only in kind from the forest, but different in history and origin. Still higher up, around 4,572 metres (15,000 ft), cold, barren, windswept terrain and permanent snow and glaciers dominate. At around 5,334 metres (17,500 ft), there is a large ice cap with several outlet glaciers.

Sex Education For Teens

source : email

Sex education for teens is extremely useful in preventing the practice of unsafe sex. It checks the rampant spread of communicable and sexually-transmitted diseases such as AIDS. It safeguards young females against unwanted pregnancies and unnecessary abortions. Most importantly, sex education instills moral principles related to sexuality in the young minds, which encourages more responsible sexual behavior -- such as refusal and resistance to peer coercion to engage in sexual activities.
Teens need to understand that sex is a natural urge and an important component of the normal life of most adults and that it must never be associated with feelings of guilt or shame. Sex education is, therefore, very crucial for young people to promote healthy and responsible sexual behavior and attitudes. With the absence of sex education during childhood and teens, young minds will learn about this “forbidden” subject from pornographic books, magazines and movies, which leave them dangerously confused about the concept of sex.
Sex education for teens must be imparted both at home by the parents as well as at the school by teachers. However, most parents are very busy or are themselves deficient in a proper understanding on this subject or are simply not comfortable discussing this subject with their kids.
This makes it all the more important to provide kids with the requisite sex education at schools as a part of the regular school curriculum. The curriculum for sex education should so be designed that it encompasses a wide range of human relationships, including sex. It is advisable to begin sex education at a very early stage of the education process. Information can be provided in small doses and in simple ways. A concentric mode of education can be adopted where the kids are exposed to more information on sex education each year. As a result of sex education, kids come to recognize sex as something very natural and do not consider it a taboo any more, nor are they extra inquisitive about topics related to sex. So, when kids become teenagers, sex is not something they would spend too much time dwelling on. Instead, the teens would spend their time on other activities.

Just 120 Trillion Miles From Home

Reposted from http://www.nytimes.com/2007/04/29/weekinreview/22basicB.html?_r=1&ref=science

Astronomers announced last week that they had found what might be the first habitable planet outside the solar system. Known poetically as Gliese 581c, the new planet is only five times as massive as the Earth and inhabits a sweet zone around a dim red star in Libra where it is neither too hot nor too cold for liquid water. The star and its retinue of planets are only 20 light years away. "We could go there," enthused Dimitar Sasselov, an astronomer at the Harvard-Smithsonian Center for Astrophysics, noting that 20 light years is next door in a galaxy 100,000 light years across. But he was speaking for the very, very long term. However near cosmically, the Gliese planet is still about 120 trillion miles away. Voyager 1, now leaving the solar system at a speed of about 39,000 miles per hour, would need more than 300,000 years to travel that far.
Physicists and engineers point out, however, that it is possible to attain much higher speeds with spacecraft that undergo a gentler but steady acceleration throughout the trip, rather than getting a short violent boost at the beginning like Voyager and current rockets do. Lawrence Krauss, a physicist at Case Western Reserve University, and author of "The Physics of Star Trek," said that a ship that could maintain an acceleration equivalent to the gravity felt on Earth would attain a velocity of half the speed of light in three months.

The technology for that much oomph is nowhere in sight, but NASA has experimented with gentler versions like solar sails, in which the spacecraft is propelled by sunlight, or ion drives, pioneered on a spacecraft named Deep Space 1, which visited a comet in 2001, in which high-energy particles do the propelling. This year a new spacecraft, Dawn, will use ion propulsion to begin a cruise around the asteroid belt. But even ion drives have to carry prohibitive amounts of fuel to reach the stars, said Marc Rayman of the Jet Propulsion Laboratory, and Dawn's project system engineer.

It would take Dawn 10,000 days and 5,000 pounds of propellant to get up to 150,000 miles per hour, which is only .02 percent of the speed of light, "which is nothing," said Dr. Rayman.

"That's an illustration of how daunting this travel is," he said. "The distances are vast, the challenges are extraordinary."

"I don't have any doubt that humankind will eventually have the technology to send spacecraft that distance," he said, adding, "I have no idea how it will be done."

Dr. Sasselov said that in the long run, in order to survive planetary catastrophes, we would want to make the trip, by whatever means.

"We don't have to go next year or even in the next 20 years," Dr. Sasselov said. But eventually, he said, "if we figure out our human affairs down on here on Earth, we'll want to be moving along."
