May be Positive and Realistic same time?
There are many people that believe about be positive mean be happy and to be funny and laughed all time. Also speak with great-short phrases that are very popular
I am not negative, never I was it really. Some times I felt sad or impotence by the unjust suffering of many persons.
Also I felt depressed by some personal situations or by relatives. But, always I recovered, in few time.
I believe in a spiritual positive-realistic mixture of thought and to dominate my mind and actions in my routine activities.
Also, I never lose my youthful ideals, neither my dreams of childhood, and I know that themselves will not comply in this real world but if they do it in my dreams, So I had been adapted to a new form to see the life, to see it with an interesting mixture of idealism and actions realistic.
I believe that a concrete demonstration, of it aforementioned, is to try to write in my Blog some diverse articles, photos, videos, comments of yesterday, today and tomorrow.
For me the time is relative, more important is the message or the actions in the human beings involved. In some cases some country, in other cases all world.
Also never we should forget the people that already passed away (arts, sciences, music, literate, good family or friends, etc.)
Never we forget them, I believe that they are the Mind and Positive Spirit of the World, without them, and some that are alive, the world has a positive future, without them I believe that nobody can save to world.
Have a good Day.

A new way to examine humanity’s impact on the environment is to consider how the world would fare if all the people disappeared.
If all human beings vanished, for example, Manhattan (New York) would eventually revert to a forested island.
Many skyscrapers would topple within decades, undermined by waterlogged foundations.
Weeds and colonizing trees would take root in the cracked pavement, while raptors nested in the ruins and foxes roamed the streets.
According to Alan Weisman (author of book “The world without Us”), large parts of our physical infrastructure would begin to crumble almost immediately. Without street cleaners and road crews, our grand boulevards and Superhighways would start to crack and buckle in a matter of months.
Over the following decades many houses and office buildings would collapse, but some ordinary items would resist decay for an extraordinarily long time.
Stainless-steel pots, for example, could last for millennia, especially if they were buried in the weed-covered mounds that used to be our kitchens.
And certain common plastics might remain intact for hundreds of thousands of years; they would not break down until microbes evolved the ability to consume them.
Now look down the next pictures about what happens at…?
* 2 Days after the disappearance of humans (New York City’s subway system completely fills with water.)
* 2 to 4 years (cracked streets become covered with weeds…)
* 20 Years (Dozens of streams and marshes form in Manhattan)
* 100 Year (The roof of nearly all houses have caved in…)
* 300 Year (New York City’s suspension bridges have fallen)
* 500 Years (Mature Forest cover the New York metropolitan area)
*5,000 Years (As the casings of nuclear warheads corrode, radioactive plutonium 239 is released into the environment.)
* 15,000 Years (The last remnants of stone buildings in Manhattan fall to advancing glaciers as a new ice age begins)
* 10 Million Years (Bronze sculptures, many of wish still retain their original shape, survive as relics of the human age)
* 1 Billion Years (The earth heats dramatically, but insects and other animals may adapt.)
* 5 Billion Years (The earth vaporizes as the dying sun expands and consumes all the inner planets.)
Trillions of Years (Ex-planet earth is in the Twilight Zone, still travel outward through space.
I’m not suggesting that we have to worry about human beings suddenly disappearing tomorrow, some alien death ray taking us all away.
Think about how long it would take to wipe out some of the things, we have created. Some of our more formidable inventions have a longevity that we can’t even predict yet, like some of the persistent organic pollutants that began as pesticides or industrial chemicals. Or some of our plastics, which have an enormous role in our lives and an enormous presence in the environment.
Wouldn’t it be a sad loss if humanity were extirpated from the planet?
Would this world be beautiful without us?
I don’t think it’s necessary for us to all disappear for the earth to come back to a healthier state.

Nobody has ever systematically looked at the sky on 100-year time scales, said Josh Grindlay, the Harvard astronomer in charge of the project. There is this whole dimension that hasn’t been explored.
The Harvard Observatory holds more than a century of astronomical records. Below (picture 1), we can see cabinets filled with photographic plates in 1891.
The great Refractor (below), which in 1850 captured the first picture of a star; images from the archives, including the Large Magellanic Cloud (1900), the constellation Sagittarius (1943) and the Rho Ophiuchus nebula (1948)
In 1889 when this was still an analog world, a young astronomer named Solon I. Bailey carefully packed two crates of glass photographic plates taken at his outpost in the Peruvian Andes for shipment to Harvard College Observatory. Carried down the mountain on mule back and across a suspension bridge to the village of Chosica, the fraile load was put on a train bound for Lima and the long voyage to Boston Harbor.
For nearly 18 months the data stream continued -more than 2,500 plates from what Mr. Bailey had quaintly named Mount Harvard- followed in the coming years by tens of thousands more from a second Peruvian station in Arequipa.
The “computer” room at the Harvard Observatory in 1891, below, where women examined glass photographic plates containing images of the sky. One of their most important tasks was looking for stars that changed periodically in brightness. (Picture 3)
The reliance on photographic plates continued until the mid-1980s when electronic imaging came of age. The eyes of the astronomers were replaced by charge-coupled devices, or C.C.D., allowing for faster, more voluminous observations with all the advantages of a searchable database.
Today, Picture 4 below, Alison Doane, curator of the glass database, compares a chart with a glass plate in her office.
Below, an observatory camera from 1891 (picture 5), and the custom-built scanner now used to digitalize the old plates, shown in binders at picture 6, is the handwritten logbooks, which researchers are working to transcribe.

Can a bunch of Garagistas Revive NASA?
To revive the space program it follow:
1) Basement brainstormers
2) Workbench concocters
3) And Garage Tinkerers
The difference between being a mad scientist and a famous inventor is the difference between failure and success
One contestant said:
“I guess I’m still in the mad-scientist phase.”

John Lennon portrays Private Gripweed in How I Won the War (1967), which is of interest to technological historians chiefly for its extensive use of authentic British World War II helmets.

Javits Convention Center in Manhattan has been changing significantly.
The show had products from 73 countries and territories this year, including some newcomers: Nicaragua, Costa Rica, Syria, Palestine, Russia, Benin, Rwanda, Uganda and Swaziland.
The National Association for the specialty food trade, which runs the event. And many of them especially from Africa, are doing it with help from Africa, are doing it with help from American agencies that work in international development. The interest in African products is a fairly new thing, and it’s growing. Americans are into trying new flavors.
Peru’s booths, included a light, herbaceous nut oil, sacha inchi, touted for its omega-3 content, and gluten-free amaranth biscuits from Cuzco foods, as well as a collection of crisp skewer-thin breadsticks, palitos, in 10 flavors.

We know that and individual that an individual’s genes and environment history- and even his or her own behavior-mold the brain overtime.
There is clear evidence that any unique features that may exist in the brains of teens are the result of social influences rather than the cause of teen turmoil.
Today teens in the U.S. and some other westernized Nations do display some signs of distress.
The peak age for arrest in the U.S. for most crimes has long been 18; for some crimes, such as arson, the peak comes much earlier.
Drug use by teens, both legal and illegal, is clearly a problem here, and suicide is the third leading cause of death among U.S. teens. Prompted by a rash of deadly school shootings over the past decade, many American high school now resemble prisons, with guards, metal detectors and video monitoring Systems, and the High School dropout rate is nearly 50 percent among minorities in large U.S. cities.
Considerable research shows that a person’s emotions and behavior continuously change brain anatomy and physiology. Stress creates hypersensitivity in dopamine- producing neurons that persists even after they are removed from the brain.
Enriched environments produce more neuronal connections for that matter, meditation, diet, exercise, studying and virtually all other activities alter the brain, and a new study shows that smoking produces brain changes similar to those produced in animals given heroin, cocaine or other addictive drugs. So if teens are in turmoil, we will necessarily find some corresponding chemical, electrical or anatomical properties in the brain.
But did the brain cause the turmoil, or did the turmoil later the brain? Or did some other factors-such as the way our culture treats its teens-cause both the turmoil and the corresponding brain properties?
Young people have extraordinary potential that is often not expressed because teens are infatilized and isolated from adults.

Some consider fatal to have feminist overtones. Do you think it’s a political film?
I think Fatal Attraction had a tremendous effect on this country when it came out. I think people brought political baggage to the film. I was astonished that so many feminists didn’t like Alex Forrest because they thought it was a terrible portrayal of a single working woman.
You can’t play somebody that represents all single women.
But she has become, I think, a symbol of women fighting back.
As an actress who is no longer in her 20s or 30s, are you frustrated with the roles you are offered in Hollywood?
I can’t complain. I think older women are very hard to write for. I really do, I mean culturally speaking. At a certain age you’re supposed to be in the back room rocking the grandchildren.
What do you do to look so young?
I think a lot of it is genetic, but I always was kind of a jock.
I went on my first triathlon in May, and my goal was just to finish, so my time was horrible…

In the fall of 2006, only 103 black students said they planned to enroll as freshmen at the University of California-Los Angeles.
That’s the lowest black enrollment in 30 years- just 2 percent of the flagship public university’s incoming class of about 4,800 first-year-students.
The impact of the bans has been mixed and has changed over time. While across the UC System the number of African-American and Latino students.
Critics say the policies are tantamount to “reverse discrimination” and strain Schools by propelling unprepared students into high level institutions. These criticisms have been the basis of legal challenges to affirmative action in courtrooms and voting booths.
