FULGURITES - PRODUCTS OF LIGHTNING FULGURITES Lechatelierite Var. Fulgurite is the varietal name given to fused Quartz, Si02, which has been fused by the action of lightning striking the Earth and locally melting the sand. The best known Fulgurites are found in Quartz sands, where the Fulgurites take the form of tubes, sometimes exceeding a half inch or more in diameter. This type of formation is called a Sand Fulgurite. As the lightning strikes the Earth and courses downward through the sand, the sand is instantly super heated (i.e., melted and fused). After cooling, glass-like hollow tubes (Fulgurites) can sometimes be located beneath the surface of the sand, generally decreasing in diameter and sometimes branching as they descend, sometimes extending for several feet.

The Future of Leap Seconds Leap seconds are added to our clocks to compensate for the Earth's slowing rotation. However, some scientists propose abolishing leap seconds in the future, redefining the way we measure time. This issue will be put to a vote in 2015.

Busy Life Meditation Busy Life, No SelfBy Joseph Goldstein I was recently thinking about some close friends who are younger than I am, raising families, with busy lives in the world. I could appreciate that it might be quite some time before they would be able to sit a long retreat, where it’s easier to access meditative depths. When we’re otherwise intensely engaged, this can be quite a challenge. So I started wondering if there was a way for people with busy lives to integrate some kind of meditation technique into their daily activities that would still touch the transformative power of the practice. The basic understanding of anatta, or ‘no-self’ – the absence of an inherently existing self – is one of the most difficult concepts to work with.

This is followed by relationship outside marriage, possession and use of drugs, intoxication from alcohol, and illegal recruitment. Science and Technology of WWII Science, Technology, and Warfare through the Ages On the face of it, few human activities would seem to be more different than war and science. War aims to kill people and destroy things, to bring one country’s military (or their whole society) under the control of another. War is primal, violent, chaotic. Science and mathematics, by contrast, seem the highest development of learning and civilization, creative and even noble activities. Science proceeds by slow, thoughtful activity, careful theory and experiment where every last detail or variable is controlled under precise conditions.
List of emoticons A simple smiley This is a list of notable and commonly used emoticons or textual portrayals of a writer's mood or facial expression in the form of icons. The Western use of emoticons is quite different from Eastern usage, and Internet forums, such as 2channel, typically show expressions in their own ways. 200 cr trees to be planted along highways: Gadkari The government plans to plant 200 crore trees along the entire 1 lakh km National Highways network across the country to employ jobless youth. “The length of National Highways in the country is one lakh kilometre. I have asked officials to come out with a plan to plant 200 crore trees along these stretches which in turn would create jobs for the unemployed on the one hand and protect the environment on the other,” Road Transport, Highways, Shipping and Rural Development Minister Nitin Jairam Gadkari said in New Delhi on Friday. A similar scheme could be implemented under MNREGA (Mahatma Gandhi National Rural Employment Gurantee Act) along the village and district roads and state highways. That has the potential to employ 30 lakh youth, he said while inaugurating a conference on “Regeneration of Rivers”. Mr.
SCIENCE SHOWOFF curated by Prof Sophie Scott. March 17th, Star of Kings. TICKET LINK: Don’t worry. We’d never do a zombie-themed gig. ZOMBIES ARE SO OVER. Exploring The Final Frontier Set on a sprawling 45-acre campus some 25 km east of Thiruvananthapuram, the Indian Institute of Space Science and Technology (IIST) appears a sedate place at first glance. The buildings are mildly futuristic and the green hills, gently rolling. But it comes as no surprise that this place has, in a matter of eight short years, contributed a little over 400 promising young scientists/engineers to various units of the Indian Space Research Organisation (ISRO). With two BTech and a new dual degree programme, and over a dozen Master’s courses and PhD programmes, IIST has come a long way since September 2007, when it was inaugurated in a temporary campus next to the Vikram Sarabhai Space Centre (VSSC) in Thumba, a suburb of Thiruvananthapuram. Tens of thousands of youngsters apply from across the country, but only 140 — the finest of the finest, promise IIST officials — will make it to Valiyamala, where IIST is located.
Projects: Self-Powered Camera We have designed a simple pixel circuit, where the pixel’s photodiode can be used to not only measure the incident light level, but also to convert the incident light into electrical energy. A sensor architecture is developed where, during each image capture cycle, the pixels are used first to record and read out the image and then used to harvest energy and charge the sensor’s power supply. We have conducted several experiments using off-the-shelf discrete components to validate the practical feasibility of our approach. We first developed a single pixel based on our design and used it to physically scan images of scenes.
