June 23rd, Author: Consequently the civilizations of the world naturally and simultaneously started developing near the rivers which initially started flowing due to the melting of glaciers near the Equator e. South India, Sri Lanka and Africa. When populations multiplied, these river waters became insufficient. Therefore some people started travelling from south to north. Such northward migration continued for several centuries and finally when these people from south India reached the banks of Himalayan Rivers, they got climatic conditions conducive to long term development of civilization on the banks of these rivers providing security of water, food and shelter for a very long time. Thousands of years later, when some of these Himalayan Rivers became non-perennial or started drying up, some of these people started moving towards Central Asia and Europe. As per ecologists this ecological cycle has been repeating itself and will get repeated after every ice age and during the beginnings of all Holocene cycles. Therefore the history of growth of civilization in the world is not 4 to 5 thousand years old but it is more than 10, years old.

On a clear, moonless night, one can often see a hazy, luminous band stretching across the ancients devised many fanciful myths to account for this “milky way.” Galileo was the first to look at this haze with a telescope and discover that it was composed of countless dim stars.

References Introduction The sun is shining from a blue sky, delivering a thousand watts of power to every square meter on the earth. It has been doing so since time immemorial, with no notable changes. The only reasonable energy source that we know of, that can keep the sun going like that, is nuclear fusion. One unavoidable by-product of fusion is a copious flux of particles called neutrinos.

Neutrino detectors on earth do find neutrinos coming from the sun, and the observed flux is of the right order of magnitude, confirming that fusion is actually taking place in the sun. But when detailed calculations of the expected neutrino flux were confronted with measurements, about 30 years ago, a significant discrepancy was found. Only about half of the expected neutrinos could be found. This anomaly persisted until quite recently, and is known as the “solar neutrino problem”.

As with many other anomalies in science, creationists e. Oard , Snelling , Sarfati have invoked the solar neutrino problem as evidence of more fundamental problems in orthodox “uniformitarian” science. It is argued, in brief, that since the neutrino flux is wrong, there can’t be enough fusion in the sun, in which case the sun can’t keep shining for billions of years, so it must be recently created.

In this FAQ , I will first describe the standard view of the sun’s internal workings, and then go on to neutrinos, what they are, and what we expect of them from the sun. After that I will discuss various possible solutions to the solar neutrino problem.

Don’t Bank On Solar Power In Winter!

Its biggest project to date has been the solar PV and solar cooling system it did for Digicel at the telecoms’ new downtown Kingston headquarters, he said. In anticipation of growing clientele, RED is awaiting approval from the St James Parish Council to construct a 3, square-foot showroom and administrative building in Montego Bay that can stock around 1, panels. Furthermore, Lyn said Jamaicans are way more educated now about solar than they were in the early s. Jamaica has an abundance of sunshine, an average of 3, hours a year in Kingston, although that falls by a quarter in more mountainous parts of the island, which tend to have heavier cloud cover.

Photovoltaic power generation uses solar panels composed of a number of solar cells containing a photovoltaic material. Photovoltaic cells convert sunlight into electrical energy, which is subsequently stored in a bank of batteries.

Nuclear fusion is the only process reasonably capable of powering the sun, and one product of this fusion is invisible particles called ‘neutrinos’. But why don’t we observe as many solar .

It consists of , solar panels that provide up to 32 MW of electricity Credit: Brookhaven National Laboratory SalesSolar energy is abundant, non-polluting and does not emit greenhouse gases responsible for global warming. Even in the northeastern United States, where sunlight is variable, solar energy helps to warm and light many buildings and can make a significant contribution to meeting demand for electricity and hot water. Solar technologies can be applied at both large and small scales.

Large commercial scale solar power plants feed electricity directly to the utility electric grid. Smaller distributed solar electricity generation by individual homes, institutions or businesses is economically feasible because New York has adopted “net metering,” which allows excess electricity generated on sunny days to flow back into the electric grid, with credit or payment from the utility company for the power generated.

PV cells often referred to as “solar cells” convert sunlight directly into electricity. Solar cells are connected together to form solar panels. Multiple panels together form the solar arrays commonly seen on roofs and as free-standing installations.

At one moment during the day, the shadow will point exactly north or south or disappear when and if the Sun moves directly overhead. That instant is local apparent noon , or The problem is that in September the Sun takes less time as measured by an accurate clock to make an apparent revolution than it does in December; 24 “hours” of solar time can be 21 seconds less or 29 seconds more than 24 hours of clock time.

As explained in the equation of time article, this is due to the eccentricity of the Earth’s orbit i. The effect of this is that a clock running at a constant rate — e.

The Babylonian Calendar after R.A. Parker & W.H. Dubberstein, Babylonian Chronology [Providence, Rhode Island, ] The beginning of the month in the Babylonian calendar was determined by the direct observation by priests of the young crescent moon at sunset after the astronomical New Moon.

There seems little call to have a modern luni-solar calendar, which keeps track of both the seasons and the Moon. Surviving luni-solar calendars, the Jewish and the Chinese , are now used mainly for ritual purposes. On the other hand, the tides are strongly affected by the phases of the moon, and sailors and fishermen may keep in mind that the tides are the strongest at the New and Full Moons.

At the same time, as ancient people were certainly aware, the lunar month matched up closely with the menses of women. The sort of feminists who wish to valorize the feminine certainly highlight the affinity of the feminine to the Moon; but I have never met any women who actually paid any attention to lunar calendar months — although female calendar buffs cannot fail but be aware of them. For the future, there is at least one conceivable reason why a luni-solar calendar might eventually be desired: When there are human colonies on the Moon, it will be of rather more practical concern than it is on Earth what phase the Moon is in, since that determines whether it is day or night outside.


The Study of the Universe On a clear, moonless night, one can often see a hazy, luminous band stretching across the sky. The ancients devised many fanciful myths to account for this “milky way. Today, we realize that this hazy band is our view from the inside of a vast disk that is home to billions of stars, including our own Sun , and vast amounts of interstellar dust. This is our galaxy — the Milky Way. Earlier in this century, Edwin Hubble’s observations led to the discovery that ours is only one of many billions of galaxies that dot the universe with each galaxy home to billions of stars.

Some, like the Milky Way, are flat disks with arcing spiral arms and regions of dense interstellar gas, called nebulae, which are active sites of star formation.

The Unknown Regions, also referred to as Unknown Space and the Unknown Territories, was a region of the galaxy located in the galactic west beyond the Outer Rim. Largely unexplored throughout galactic history, it remained a mystery to space travelers and served as a source of tales and wonders.

August South Solar of Bunratty Castle The solar was a room in many English and French medieval manor houses , great houses and castles , generally situated on an upper storey, designed as the family’s private living and sleeping quarters. Those of highest status would be at the end, often on a raised dais , and those of lesser status further down the hall.

But a need was felt for more privacy to be enjoyed by the head of the household, and, especially, by the senior women of the household. The solar was a room for their particular benefit, in which they could be alone and away from the hustle, bustle, noise and smells including cooking smells of the Great Hall. In the medieval house of Great Dixter , in East Sussex , it consists of 3 rooms and a fireplace from the late 15th century.

Examples[ edit ] Beverston Castle near Tetbury in England , dating from the 13th century, has a surviving but ruined solar in the south tower of the west range, with a vaulted undercroft below. Edlingham Castle in Northumberland, castle in ruins but Solar tower is mostly intact. Which is the home of the late British gardener and author Christopher Lloyd , has a recreated solar.

Tattershall Castle, Lincolnshire , has hall and large solar block later converted into a tower.

Acknowledgements Introduction his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale. It is not about the theory behind radiometric dating methods, it is about their application, and it therefore assumes the reader has some familiarity with the technique already refer to “Other Sources” for more information.

As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale. To get to that point, there is also a historical discussion and description of non-radiometric dating methods. A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging.

These are often characterised as the norm, rather than the exception. I thought it would be useful to present an example where the geology is simple, and unsurprisingly, the method does work well, to show the quality of data that would have to be invalidated before a major revision of the geologic time scale could be accepted by conventional scientists. Geochronologists do not claim that radiometric dating is foolproof no scientific method is , but it does work reliably for most samples.

It is these highly consistent and reliable samples, rather than the tricky ones, that have to be falsified for “young Earth” theories to have any scientific plausibility, not to mention the need to falsify huge amounts of evidence from other techniques. This document is partly based on a prior posting composed in reply to Ted Holden. My thanks to both him and other critics for motivating me.

Background Stratigraphic Principles and Relative Time Much of the Earth’s geology consists of successional layers of different rock types, piled one on top of another. The most common rocks observed in this form are sedimentary rocks derived from what were formerly sediments , and extrusive igneous rocks e.

While the government offers tax credits and other incentives for you to go solar, many homeowner associations seem to be behind the times. So can your HOA dictate everything you do on your personal property? Not anymore when it comes to solar power. Many homeowners discover, after-the-fact, that their request to install solar is denied by homeowners association board members, due to clauses written in their HOA bylaws. Community officials believe solar panels change the pre-planned aesthetics and landscape of the neighborhood, and generally look out of place.

The NY-Sun Solar PV program offers incentives to reduce the installation costs of solar PV for both residential and commercial customers. See link at right (NY-Sun Solar PV Incentive Program), for incentive information and a solar PV clean power cost estimator.

Big thanks to everyone who stopped by. The good news is that all applications that were submitted before July 2 will get the full The not-so-great news is that all apps submitted after July 2, for ground-mount systems, will receive There is still money to be made here, just not as much. You can read their press release here. Among the guests were: As usual, Ben kept asking people over and over to email in their experiences, data, and information.

But while the OPA have kept asking for this information, Ben said during his presentation paraphrasing: Does anyone here feel the new model is fair and they just don’t like how it was announced?

Solar calendar

The Egyptians appear to have been the first to develop a solar calendar, using as a fixed point the annual sunrise reappearance of the Dog Star —Sirius, or Sothis—in the eastern sky, which coincided with the annual flooding of the Nile River. Ptolemy III Euergetes of Egypt, in the Decree of Canopus bc , introduced an extra day every four years to the basic day calendar this practice also having been introduced in the Seleucid calendar adopted in bc.

In the Roman Republic, Julius Caesar in 45 bc replaced the confused Roman republican calendar , which probably was based on the lunar calendar of the Greeks, with the Julian calendar. The Julian calendar assigned 30 or 31 days to 11 months but fewer to February; it allowed for a leap year every four years. The Julian calendar, however, made the solar year slightly too long by adding a full quarter of a day annually—the solar year actually runs

Today I wanted to share information about running air conditioning on solar power. When I was first planning to move into my tiny house, considering the possibility of running a solar powered air conditioner and cooling system weighed heavily on my mind.

The details include a 30 page description of he design and construction process, a photo gallery, and a detailed thermal analysis spreadsheet. This is the most carefully thought out energy retrofit I have seen. R40 Larsen Truss walls, triple glazed R6 super windows, glazing revamped for passive solar heating, a new solarium, a hand crafted masonry heater, and much more. In addition to a very good thermal envelope. Like most good designs, this one is simple and robust without a lot of gadgetry.
