Super Moon

Caption for the above photograph: Because the moon is tidally locked (meaning the same side always faces Earth), it was not until 1959 that the farside was first imaged by the Soviet Luna 3 spacecraft (hence the Russian names for prominent farside features, such as Mare Moscoviense). And what a surprise -­ unlike the widespread maria on the nearside, basaltic volcanism was restricted to a relatively few, smaller regions on the farside, and the battered highlands crust dominated. A different world from what we saw from Earth.

Today marks the last full moon of winter.  It's special in that it is unusually close to the Earth.  The Farmers' Almanac terms the March full moon as the Full Worm Moon:
As the temperature begins to warm and the ground begins to thaw, earthworm casts appear, heralding the return of the robins. The more northern tribes knew this Moon as the Full Crow Moon, when the cawing of crows signaled the end of winter; or the Full Crust Moon, because the snow cover becomes crusted from thawing by day and freezing at night. The Full Sap Moon, marking the time of tapping maple trees, is another variation. To the settlers, it was also known as the Lenten Moon, and was considered to be the last full Moon of winter.
A few days ago, in the wake of the huge Japanese earthquake, a commentator on CNN remarked that the proximity of the Moon to the Earth can affect tsunamis and earthquakes.

This is Only the Beginning

Fasten your seatbelts. Brace for impact. This is only the beginning. The Japanese earthquake struck just over a week ago.  In scanning the blogs and tweets for the general mood, I find a shrill apocalyptic consensus rising online.  On early March 18, Vinay Gupta (@leashless on Twitter) tweeted: "The air stinks of war if you can feel it, the acrid edge of blood and smoke. You can't have revolutions in the middle east without the risk. And we're all tottering on the edge of a global financial collapse, which the oil price spike / crippled Japan combo may trigger."

Japan's Disaster: Pets, Animals and Omens

Image Source: Global Animal.

Among reports on the earthquake, tsunami, nuclear plants and radiation, devastation of coastal towns, tales of survivors and mass death, news is surfacing about Japan's lost pets that have survived the disaster.  As if on time delay, the world's concern for Japan deepened as pictures of stranded animals made the rounds on the Web today.  Nippon SPCA is here. Japan Earthquake Animal Rescue and Support (a  coalition of three groups — HEART-TokushimaAnimal Garden Niigata, and Japan Cat Network) is here.  In addition, there are some reports circulating about animals' sensitivity to these terrible events - with some pointing to the superstition that animals respond to coming earthquakes before we anticipate them (as with my post here).  In both cases, our perceptions of animals mirror our anxiety and emotions surrounding this intensifying crisis.

Mission to Mercury

For weeks now, space-exploration-related Websites have been anticipating the entry of NASA's Messenger craft into Mercury's Orbit today. The craft has a heat shield made of ceramic cloth to shield Messenger from temperature extremes as high as 425 degrees Celcius and -185 degrees Celcius.  The cloth keeps the instruments consistently at room temperature.  It has taken more than six years for Messenger to travel to Mercury and line it up so that it enters the planet's orbit.

The planet was previously fleetingly photographed by Mariner 10 (1974-1975), and by Messenger itself during a fly-by in 2008. Machines Like Us reports that the Deputy Project Scientist, Louise Prockter's reflected on the mission as follows:
On receipt of ... early images of Mercury, Prockter writes: "How often in your life do you get to see something completely unexplored?...My first feeling was one of complete joy and disbelief – a perfect, beautiful, gibbous Mercury filled the screen, showing an incredible level of detail."
This mission will bring unprecedented photographs of the planet, which is slightly larger than our Moon, to public attention over the coming months.

Large Hadron Collider also a Time Machine?


Machines Like Us is reporting that two scientists working at CERN theorize that the Large Hadron Collider may enable time travel:
If the latest theory of Tom Weiler and Chui Man Ho is right, the Large Hadron Collider – the world's largest atom smasher that started regular operation last year – could be the first machine capable causing matter to travel backwards in time. "Our theory is a long shot," admitted Weiler, who is a physics professor at Vanderbilt University, "but it doesn't violate any laws of physics or experimental constraints."

One of the major goals of the collider is to find the elusive Higgs boson: the particle that physicists invoke to explain why particles like protons, neutrons and electrons have mass. If the collider succeeds in producing the Higgs boson, some scientists predict that it will create a second particle, called the Higgs singlet, at the same time.

According to Weiler and Ho's theory, these singlets should have the ability to jump into an extra, fifth dimension where they can move either forward or backward in time and reappear in the future or past.

"One of the attractive things about this approach to time travel is that it avoids all the big paradoxes," Weiler said. "Because time travel is limited to these special particles, it is not possible for a man to travel back in time and murder one of his parents before he himself is born, for example. However, if scientists could control the production of Higgs singlets, they might be able to send messages to the past or future."

Rationalism and Anti-Rationalism

Image: Ward Shelley.  Image Source: Boing Boing.

A few days ago, Boing Boing ran a piece about a great graphic depiction of the history of Science Fiction by artist Ward Shelley (Hat tip: Boing Boing via Lee Hamilton).  The history is symbolically presented as a series of interconnected organs, as in a medical diagram of a body.  The section above is the one that interests me the most, and is relevant for understanding the origins of ideas that are floating around at our turn of the Millennium.  I sense that the great conflict between Rationalism and Anti-Rationalism, embodied respectively in the Enlightenment (as in: Science) and in Romanticism (as in: Fiction) is now reaching a point where the two have reconverged almost completely.  After two hundred years of wars, revolutions, genocides, as well as political, social, industrial and technological revolutions, the West's Yin and Yang are combining to form a mashed-up shade of gray.  Truth has become fiction and fiction has become truth.  Reality has become unreal and vice versa.  Shelley's whole image is below the jump; you can click on it to see it close up.

Capturing the Most Violent Event in the Universe

Caption for the above phorograph: The image ... is an enlargement of a combined image obtained with the Space Telescope Imaging Spectrograph (STIS) onboard the NASA/ESA Hubble Space Telescope through a clear filter (shown in blue) and a red filter (shown in red). The region shows the star-formation taking place around the gamma-ray burst region in the galaxy ESO 184-G82.

Hubble telescope has captured the most violent event in the universe - a rare combination of a gamma ray burst with an exploding supernova.  From the Daily Galaxy:
In this new image from the Hubble Space Telescope, you'll see a spectacular gamma ray burst and supernova as a bright point in the irregular galaxy located approximately 820 million light years from the Earth. An international team of researchers made the discovery using NASA's Swift satellite.

"That we have observed a gamma ray burst and a supernova simultaneously is unusual and it gives us a long awaited confirmation of the theory that gamma ray bursts are indeed associated with exploding giant stars", explains Johan Fynbo, astrophysicist at the Dark Cosmology Center, Niels Bohr Institute at the University of Copenhagen. ...

"Only about one out of 10,000 supernovae produce gamma ray bursts, and gamma ray bursts in the relatively near universe are even more rare, so it gives us a unique opportunity to study the phenomena in detail. When you have one that is so near, it is like a clock telling you that the star is dying just NOW, and you can follow the early phases and the entire development of the supernova explosion that follows", explained Johan Fynbo.

It is only the very large, massive stars of more than 30-40 solar masses that produce gamma ray bursts. What happens is that when the star dies, it collapses and forms a black hole. If the black hole spins very quickly, a jet might appear - a gamma ray burst, which is powerful, high-energy radiation, which shoots out at nearly the speed of light. It happens very quickly and only lasts a few seconds.

A Future in Glass

Corning has put out a corporate video (here and here) envisioning a future filled with its glass products (Hat tip: Dump.com via @LillyLyle).  Like my recent comments on Audi commercials that suggest the future is here, or almost here, these products are paired with values associated with the rise of the tech-oriented social classes.  It's a vision of ease, convenience, accessibility, cleanliness - and streamlined wealth:
Can you imagine organizing your daily schedule with a few touches on your bathroom mirror? Chatting with far-away relatives through interactive video on your kitchen counter? Reading a classic novel on a whisper-thin piece of flexible glass?
Corning is not only imagining those scenarios – the company is engaged in research that could bring them alive in the not-too-distant future. You can get a glimpse of Corning’s vision in the new video, “A Day Made of Glass.”
Corning Chairman and CEO Wendell Weeks says Corning’s vision for the future includes a world in which myriad ordinary surfaces transform “from one-dimensional utility into sophisticated electronic devices.” ...
Glass is the essential enabling material of this new world. “This is a visual world – so transparency is a must,” explains Wendell. But that’s just the beginning. Ubiquitous displays require materials that are flexible, durable, stable under the toughest of environmental conditions, and have a cool, touch-friendly aesthetic. And not just any glass will do. This world requires materials that are strong, yet thin and lightweight; that can enable complex electronic circuits and nano functionality; that can scale for very large applications, and that are also environmentally friendly. ...
Does the world showcased in “A Day Made of Glass” seem like something out of a fantasy movie? Jim Clappin, president of Corning Glass Technologies, reminds us that, just a decade ago, pay phones, VCRs, and film cameras were also commonplace. Today, we’re accustomed to movies streaming on demand to a 60-inch television hanging on the wall and to video calls on notebook computers, essentially for free.
“The consumer trend driving our vision for tomorrow is very clear,” Jim says. “We all want to be connected with what we want…when we want…anywhere…and with great ease. Corning’s innovations in glass will enable this journey to continue.”
See the video and popular reactions to it below the jump.  The reactions remind me of one of my earlier posts, in which I talked about an unanticipated anti-tech backlash in the future.
