These days our day jobs are getting pretty busy. Beam dump at Point 6 After the question “what is 7 TeV?” First of all, let’s stay humble. 27 km in circumference,100 m underground,8 stories high,12,500 tons, etc. But all this huge equipment is just support for the diminutive stars: bunches of 1011 protons,each 7 cm long and 1 mm in diameter (about the size of a mechanical pencil lead). That really isn’t much stuff considering that macroscopic things contain around 1023 atoms. So, what about this 7 TeV thing? A TeV is actually a very tiny amount of energy. On the other hand, we have to give these protons some credit. Of course there can be quite a few protons spinning around the LHC at one time, and though only a few interact each time the bunches cross, we can wonder how much total energy is in the beam. What would happen if the beam were to somehow go astray and hit the beam pipe and surrounding apparatus? So, to the energies…
Index of / IGCSE Geography - Revision guide - Human settlements means the totality of the human community - whether city, town or village - with all the social, material, organizational, spiritual and cultural elements that sustain it. The fabric of human settlements consists of physical elements and services to which these elements provide the material support. The physical components comprise, Shelter, i.e. the superstructures of different shapes, size, type and materials erected by mankind for security, privacy and protection from the elements and for his singularity within a community; Infrastructure, i.e. the complex networks designed to deliver to or remove from the shelter people, goods, energy or information; Services cover those required by a community for the fulfilment of its functions as a social body, such as education, health, culture, welfare, recreation and nutrition. Human settlements are the spatial dimension as well as the physical expression of economic and social activity. source
India is building Solar Canals to Produce Energy while Slowing Water Loss Gandhinagar, April 23: Close on heels of commencing use of wastelands in northern districts and rooftops in towns and cities, Gujarat is set to potentially use the existing 19,000 km-long network of Narmada canals across the State for setting up solar panels to generate power. The Chief Minister, Mr Narendra Modi, will inaugurate the first of a series of this project, known as Canal Solar Power Project, when he launches a 1 megawatt (mw) pilot project, which is already commissioned, on Narmada branch canal near Chandrasan village of Kadi taluka in Mehsana district on Tuesday. Last week, he inaugurated a 600-MW solar power project spread across 11 districts. Gujarat, which invests nearly Rs 2,000 crore an year on renewable energy, has attracted investments of Rs 9,000 crore so far on solar energy projects. Energy, water security Today, Gujarat has about 458 km of open Main Canal, while the total canal length, including sub-branches, is about 19,000 km at present. Related:
Welcome to the Multiverse | Cosmology Theoretical cosmologist isn’t one of the more hazardous occupations of the modern world. The big risks include jet lag, caffeine overdose, and possibly carpal tunnel syndrome. It wasn’t always so. On February 17, 1600, Giordano Bruno, a mathematician and Dominican friar, was stripped naked and driven through the streets of Rome. These days, cosmologists like me may be safer, but our ideas have grown only more radical. Also like Bruno, cosmologists are reaching far beyond what observational evidence can tell them. The extent of what astronomers can see is frustratingly limited by the speed of light: one light-year (about six trillion miles) per year. Obviously, we don’t know what the unobservable part of the universe looks like. Here we are not talking about disconnected universes, but rather what we cosmologists call pocket universes. For all the parallels, modern physicists are quite unlike Bruno in one crucial way. That’s where the multiverse comes from.

Shanie_Nash: Didactic lesson planned, using... 99 Resources to Research & Mine the Invisible Web College researchers often need more than Google and Wikipedia to get the job done. To find what you're looking for, it may be necessary to tap into the invisible web, the sites that don't get indexed by broad search engines. The following resources were designed to help you do just that, offering specialized search engines, directories, and more places to find the complex and obscure. Search Engines Whether you're looking for specific science research or business data, these search engines will point you in the right direction. Turbo10: On Turbo10, you'll be able to search more than 800 deep web search engines at a time. Databases Tap into these databases to access government information, business data, demographics, and beyond. GPOAccess: If you're looking for US government information, tap into this tool that searches multiple databases at a time. Catalogs If you're looking for something specific, but just don't know where to find it, these catalogs will offer some assistance. Directories
Waiting For New Universes : 13.7: Cosmos And Culture How long is long enough when it comes to waiting for a new cosmology? How long will scientists, and everyone else, wait for an exciting but speculative theory to find some basis in experiment? Sean Carroll's new column in Discover Magazine recently made its debut with a wonderful piece on the multiverse (a longer explanation of the ideas also appears here). If you have never heard the term before, the multiverse is a universe of universes. The multiverse has become a popular topic in cosmological circles. Now don't get me wrong, I would love for the multiverse to exist. But the questions I want to take up today are simply these: What do you do with a theory that can only explain what you see by assuming the existence of a whole lot more you can't see? This debate about science turning from the universe we can observe to potential or implied universes we can't has heated up over the last decade. Many folks are hard at work looking for observational consequences of the multiverse idea.
