Ten Things Everyone Should Know About Time

Ten Things Everyone Should Know About Time
“Time” is the most used noun in the English language, yet it remains a mystery. We’ve just completed an amazingly intense and rewarding multidisciplinary conference on the nature of time, and my brain is swimming with ideas and new questions. Rather than trying a summary (the talks will be online soon), here’s my stab at a top ten list partly inspired by our discussions: the things everyone should know about time. [Update: all of these are things I think are true, after quite a bit of deliberation. Not everyone agrees, although of course they should.] 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.

SIMBAD Astronomical Database SIMBAD on the Web is the WWW interface to the SIMBAD database. It offers the following functionalities: Query by identifiers and around identifiers Query by coordinates, specifying the radius and the equinox Query by bibcode and partial bibcode Sampling with a set of physical criteria Query by lists of objects, coordinates or bibcodes Display charts for list of objects resulting from coordinates query Moreover, the interface provides links with many other data services :

Cold thermogenesis, anti-aging, and how to repair your DNA I’d like to talk about cold thermogenesis and its effects on telomere length in DNA and the resultant anti-aging. What is it? Neatly summed up as regularly freezing your butt of it can entail things like ice baths, cold showers, freezing buckets of water over the head, basically extreme exposure to cold. Cold thermogenesis not for the fainthearted. Recently experiencing a revival from its previous incarnation as cold water dousing due partly to the new research done by Dr Jack Kruse. Dr Kruse found that cold thermogenesis combined with a fat based paleo diet caused a lengthening of the telomeres thought to be responsible for aging.

Perhaps you think you said something about dinner plans, domestic chores or work. And you probably did. The Strange Physics—and Singular Sights—Inside Black Holes It is late December and snow is swirling as Andrew Hamilton coasts up to his office at the University of Colorado’s Boulder campus, in the foothills of the Rockies. On a blustery day like today, most of his colleagues arrive in SUVs or at least in cars shod with all-season tires. Hamilton rides in on his Cannondale mountain bike.

FOLLOW-UP: What exactly is a 'wormhole'? Have wormholes been proven to exist or are they still theoretical? Richard F. Holman is a professor of physics at Carnegie Mellon University. He offers this response: Wormholes are solutions to the Einstein field equations for gravity that act as "tunnels," connecting points in space-time in such a way that the trip between the points through the wormhole could take much less time than the trip through normal space. Voyager - The Interstellar Mission Pioneers 10 and 11, which preceded Voyager, both carried small metal plaques identifying their time and place of origin for the benefit of any other spacefarers that might find them in the distant future. With this example before them, NASA placed a more ambitious message aboard Voyager 1 and 2-a kind of time capsule, intended to communicate a story of our world to extraterrestrials. The Voyager message is carried by a phonograph record-a 12-inch gold-plated copper disk containing sounds and images selected to portray the diversity of life and culture on Earth. The contents of the record were selected for NASA by a committee chaired by Carl Sagan of Cornell University, et. al.

Breakthrough study overturns theory of 'junk DNA' in genome Science correspondent Ian Sample uses a visual aid to explain the implications of the new research. Video: Guardian Link to video: What the Encode project tells us about the human genome and 'junk DNA' Long stretches of DNA previously dismissed as "junk" are in fact crucial to the way our genome works, an international team of researchers said on Wednesday. It is the most significant shift in scientists' understanding of the way our DNA operates since the sequencing of the human genome in 2000, when it was discovered that our bodies are built and controlled by far fewer genes than expected. Now the next generation of geneticists have updated that picture. The results of the international Encode project will have a huge impact for geneticists trying to work out how genes operate.

The Secret of the Fibonacci Sequence in Trees As I headed to the exhibit where the hamadryas baboons ( Papio hamadryas ) resided, I knew something interesting would happen over the next few hours. As I walked into the exhibit, I found two mothers pulling their infants' tails to keep them from straying. This particular act reminded me of how some parents put leashes on their children so they won't wander too far. This example demonstrated how similar the behavior of hamadryas baboons and humans can be. Throughout my life I have enjoyed observing animals and the way they interact with their surroundings. Walking through parks I have watched squirrels, birds and other animals, always curious to know what their actions meant.

The Cutting-Edge Physics of a Crumpled Paper Ball Take a piece of paper. Crumple it. Before you sink a three-pointer in the corner wastebasket, consider that you’ve just created an object of extraordinary mathematical and structural complexity, filled with mysteries that physicists are just starting to unfold. “Crush a piece of typing paper into the size of a golf ball, and suddenly it becomes a very stiff object. The thing to realize is that it’s 90 percent air, and it’s not that you designed architectural motifs to make it stiff. Time travel Time travel is the concept of moving between different points in time in a manner analogous to moving between different points in space, generally using a theoretical invention, namely a time machine. It has a commonly recognized place in philosophy and fiction, but has a very limited application in real world physics, such as in quantum mechanics or wormholes. Although the 1895 novel The Time Machine by H.

10 Strange Things About The Universe Space The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ?273.15°C, where the motion of all particles stops completely.
