How to Navigate by the Stars

How to Navigate by the Stars
Explorers have used the stars as a compass for millennia, and if you’re out having adventures at night, you should add the skill to your arsenal. (If nothing else, it’s a killer party trick.) Here’s how to transform the night sky into your personal roadmap. 1) Learn the Big Three According to the Royal Naval Academy, 58 stars are handy for navigation. 2) Find the North Star It’s always within one degree of true north. 3) Shoot for the Moon If you can find Orion’s sword, following its point will show you south. 4) Down Under? The North Star isn’t visible below the equator. 5) Move Like a Star Like the sun, stars skate east to west. 6) Take a Survey Forgot to memorize your constellations?

How the world will look like in 100 years from now Have you ever wondered how the world will be in 100 years? No one can know it from now but highly-regarded scientists (physicists, biologists, sociologists) studying the evolution of the society, human life and the world in general make such kind of predictions based solely on scientific data. According to their publications in scientific journals, see how the world might look like in 100 years from now. Embedded computers According to futurologists Ian Pearson and Patrick Tucker, by 2050 the human body will be embedded with computers, at least in a big part of the population, and by 2075 most of the inhabitants of the developed world will have some kind of chips built in their brains to make them work faster and share thoughts in the form of computer files. Superhuman geniuses Developments in genetic engineering and robotics will create human geniuses who will live forever. Communication by thought transmission The transmission of thought will be taken for granted by scientists.

Top 10 Mysteries Surrounding Ancient Aliens Mysteries Ancient aliens is the idea that aliens visited earth in the past. The idea of ancient aliens is not a new one either. Imagination is one of the most powerful tools in humanity’s evolutionary struggle for survival. As a race, we are hardwired to consider important concepts, such as the creation of life on Earth and the history of people on this planet. The idea of evolution has been used to describe the gradual change of traits that living organisms undergo over time, which is related to the environment, but it doesn’t explain how the biological cells of human’s first ancestor were spawned. The idea surrounding ancient aliens is a basic one. This concept is related to the religious practice of a cargo cult, which can be seen in modern day pre-industrial tribal societies. It has been proposed that, with the current age of the universe and its vast number of stars, if the Earth was typical, extraterrestrial life should be common. Modern Technical Advancement

What is quantum superposition? - Curiosity Quantum matter can be difficult to study. While physicists have come a long way in the research of this microscopic science, some things are still a mystery because quantum matter can behave so erratically. Einstein's theory of relativity and various other laws of physics tend to fall apart at the subatomic level of quantum physics, because photons -- or tiny particles of light -- seem to change form randomly, and possibly change simply in observation. Niels Bohr, a famous Danish physicist, proposed the Copenhagen interpretation, which revolves around quantum superposition. Quantum superposition is the term physicists use to describe the manner in which quantum particles appear to exist in all states simultaneously. Recently, scientists at the University of California, Santa Barbara, produced the first experiment in which quantum superposition in a visible object was observed.

How Humans Are Changing the Planet—in 7 Dramatic GIFs - Rebecca J. Rosen Watch as Las Vegas booms, the Amazon disappears, and Dubai grows out into the sea. Google today released an "interactive timelapse experience" that allows users to explore millions of satellite images captured over the last quarter-century -- 25 years of immense growth and destruction. "We believe this is the most comprehensive picture of our changing planet ever made available to the public," Google said in a statement. The project was built in conjunction with the U.S. "Much like the iconic image of Earth from the Apollo 17 mission--which had a profound effect on many of us--this time-lapse map is not only fascinating to explore," Google Earth's Rebecca Moore writes, "but we also hope it can inform the global community's thinking about how we live on our planet and the policies that will guide us in the future." Here are seven of the most dramatic changes, presented in GIF form.

'Monster' cosmic blast zipped harmlessly by Earth WASHINGTON (AP) — Astronomers call it the monster. It was the biggest and brightest cosmic explosion ever witnessed. Had it been closer, Earth would have been toast. Orbiting telescopes got the fireworks show of a lifetime last spring when they spotted what is known as a gamma ray burst in a far-off galaxy. The only bigger display astronomers know of was the Big Bang — and no one, of course, was around to witness that. "This burst was a once-in-a-century cosmic event," NASA astrophysics chief Paul Hertz said at a news conference Thursday. But because this blast was 3.7 billion light-years away, mankind was spared. A gamma ray burst happens when a massive star dies, collapses into a brand-new black hole, explodes in what's called a supernova and ejects energetic radiation. A planet caught in one of these bursts would lose its atmosphere instantly and would be left a burnt cinder, astronomers say. Scientists might be able to detect warning signs of an impending gamma ray burst. View gallery

Gobekli Tepe's Cosmic Blueprint Revealed Report by Andrew Collins author of From the Ashes of Angels (1996), The Cygnus Mystery (2006) and Beneath the Pyramids (2009) On a hilly ridge called Göbekli Tepe in the Taurus Mountains of southeast Turkey, near the ancient city of Sanliurfa, archaeologists have uncovered the oldest stone temple complex in the world. Constructed most probably during the second half of the tenth millennium BC, some 7,000 years before Stonehenge and the Great Pyramid, the site consists of a series of rings of enormous T-shaped pillars, many bearing carved reliefs of Ice Age animals, strange glyphs and geometric forms. But what exactly were these stone enclosures used for, and were they aligned to the stars? In the knowledge that megalithic monuments worldwide have been found to possess alignments towards celestial bodies, it is reasonable to suggest that something similar might have been going on at Göbekli Tepe, with the most obvious candidates for orientation being the various sets of twin pillars. 1.

Junk Worth Knowing | You never knew what you were missing. Dark Plasma Theory DNA Phantom Effect INTRODUCTIONIn this contribution I am going to describe some observations and interpretations of a recently discovered anomalous phenomenon which we are calling the DNA Phantom Effect in Vitro or the DNA Phantom for short. We believe this discovery has tremendous significance for the explanation and deeper understandings of the mechanisms underlying subtle energy phenomena including many of the observed alternative healing phenomena [1,2]. This data also supports the heart intelligence concept and model developed by Doc Lew Childre [3,4]. (See also contributions by Rollin McCraty and Glen Rein in this volume). This new phenomenon -- the DNA phantom effect -- was first observed in Moscow at the Russian Academy of Sciences as a surprise effect during experiments measuring the vibrational modes of DNA in solution using a sophisticated and expensive "MALVERN" laser photon correlation spectrometer (LPCS) [5].

Learn Plants Now! » Start Learning Plant Families Here is an overview of five common families of flowering plants. The list includes two of the top three families – the Asteraceae (Aster family) and the Fabaceae (Legume family) – but does not include the Orchidaceae (Orchid family). We’ll look at orchids later – they deserve a session entirely to themselves. The families included here, and the approximate number of species they represent, are: Acanthaceae (Acanthus family) – 2,500 speciesAsteraceae (Aster family) – 23,000 speciesFabaceae (Legume family) – 19,400 speciesRubiaceae (Coffee family) – 10,000 speciesVerbenaceae (Verbena family) – 2,000 species Add up these numbers and you’ll see that these 5 families represent more than 57,000 species of flowering plants, so the chances are good that you’ll be able to find representatives of each of these families no matter where you live. To make the best use of this information, be sure you know the 19 Basic Botanical Terms and are using the Plant Profile Sheet when studying plants.

Gearing up to search for gravity waves In the Newtonian view of the world, binary star systems should remain in a stable orbit in perpetuity, no matter how massive the objects or how close the orbit. But with general relativity, that changes; energy gets carried away from the system in the form of gravity waves, which gradually causes the orbit to decay, ultimately leading to a merger. By observing binary systems of massive objects, we've determined that general relativity gets it right. These systems behave just as general relativity predicts, giving us confidence that the theory is correct. It's not for lack of trying. LIGO's design is very simple. To increase sensitivity, the LIGO project also operated two detectors, one in Louisiana, the other in Washington. If LIGO didn't detect anything, there were two potential explanations. Both of those issues are now being addressed. By 2017, we should be able to detect about 10 events a year.

DNA trick throws ageing into reverse - health - 29 November 2010 A technique to keep the tips of your chromosomes healthy could reverse tissue ageing. The work, which was done in mice, is yet more evidence of a causal link between chromosome length and age-related disease. Telomeres, the caps of DNA which protect the ends of chromosomes, shorten every time cells divide. But cells stop dividing and die when telomeres drop below a certain length – a normal part of ageing. The enzyme telomerase slows this degradation by adding new DNA to the ends of telomeres. Mariela Jaskelioff and her colleagues at the Dana Farber Cancer Institute in Boston, Massachusetts, engineered mice with short telomeres and inactive telomerase to see what would happen when they turned the enzyme back on. Four weeks after the team switched on the enzyme, they found that tissue had regenerated in several organs, new brain cells were developing and the mice were living longer.
