Is Albert Einstein's Special Relativity incompatible with the very equations upon which science's greatest theory is built? New observations made by many scientists and engineers appear to contradict the great scientist's ideas. Apparently there are implicit contradictions present within Relativity's foundational ideas, documents and equations. One individual has even pointed that quotations from the 1905 document and Einstein's contemporaries as well as interpretations of the Relativity equations clearly and concisely describe a confused and obviously erroneous theory. It is time therefore, for science to update its thinking on this theory with a comprehensive analysis of the history leading up to, during and after that revolutionary year of Special Relativity.

As this is the 100 year anniversary of the original release of Special Relativity, a review of the original assumptions, documents and ideas which led to the acceptance of this theory is timely and warranted. Every year millions of students are taught this theory without a critical analysis of Relativity. Relativity Theory consists of its two variants Special Relativity and General Relativity and is considered the cornerstone of modern physics.

Albert Einstein borrowed from the ideas of Fitzgerald, Lorentz and Voigt to create a new concept of the universe. His first work in this regard later came to be known as Special Relativity and contained many controversial ideas which today are considered axiomatic. Amongst these are Length Contraction, Time Dilation, the Twin Paradox and the equivalence of mass and energy summarized in the equation E=mc2.

This equation became the shining capstone of the new theory along with its first & second postulates, namely, that the laws of nature are the same from all perspectives and that the speed of light 'c' is constant in a vacuum regardless of perspective. Further, the theory also predicted an increase in mass with velocity. Numerous examples have been given of the 'proof' of the validity of Special Relativity.

Most notably, experiments using particle accelerators have sped particles to incredible velocities which apparently provide confirmation of Einstein's theory. However, doubts remain in the scientific community who have never totally given up the comfort of a Newtonian world view. This is readily apparent in that they refer to the Newton's 'Law' of Gravitation whilst Special Relativity (SR) and General Relativity (GR) are given the polite attribution 'The Theory of' or simply SR 'theory' and GR 'theory.' Einstein would continue working on the ideas of Special Relativity until producing the aforementioned even more controversial treatise.

In his later more comprehensive work called the Theory of General Relativity (1916), Einstein proposed a major re-thinking of cosmology. He conceived of a space time continuum that is curved by mass; in other words, planets, stars, galaxies and other stellar objects cause a curvature of space time. The movement of these objects are determined by the aforementioned curvature.

As a result of these ideas, our understanding of geometry, math, physics, science and the universe would never be the same. However, some scientists are reporting that speed of light is not constant from different experimental observations. One has even reported errors in the fundamental equations. If so, this would require a major rethinking of the known cosmological models and assumptions of modern physics.

Electricity is a fundamental pillar to any modern society. Unfortunately, we need fuel to create electricity. This brings us to the subject of biomass as a new source of power.

Using Biomass Power for Our Electric Needs

Biomass is a term used to describe natural, biological materials that can be used as fuel to produce energy. Biomass is a broad term that includes many different types of fuels, from garbage to landfill gas to ethanol. The electricity biomass produces can be used to power many different things from industries to homes, and once properly researched and put into use, biomass will definitely cut down on the world's use of fossil fuels and other harmful sources of energy.

The most common types of biomass can be grouped into one of three categories. Wood (and related) products are things like lawn clippings, wood chips, leftover wood scraps from lumber production, dead trees and leaves. Garbage products are items within garbage that people generate that can be used to burn as fuel, or landfill gases, which are produced when garbage rots (methane). Ethanol and biodiesel are both fossil fuel replacements made from either corn or other crops (ethanol) or vegetable oil and animal fat (biodiesel). All of these can result in biomass fuel to produce electricity.

The landfill gas, also known as biogas or methane, is often collected by landfill owners or farmers to be used as fuel. The burning of this fuel can either power a generator for electricity or be used to heat property. The vegetation or wood related products can be pressed into pellets, and then used as fuel for heat and electricity generation. Ethanol and biodiesel are of even more interest in the world climate these days, as they are both used to power cars and other vehicles. Ethanol and biodiesel are much cleaner burning than fossil fuels, and less expensive to produce since they come from waste which is easy to find in our modern world. Both types of fuel are also biodegradable, making them safer for the environment. While neither fuel can be used in all types of cars at present, car manufacturers are working to make more vehicles that will run on these alternative fuels. Any of these approaches can be used as electricity biomass platforms.

While the idea of using electricity biomass as a power platform may seem far-fetched at present, the resources are already in place to use biomass as fuel. What needs to be done right now is more research on how to use these biomass fuels efficiently, and without the stigma of "burning garbage". Other fuels at present are much more user-friendly and easy to store, as they are concentrated and in familiar formats.

Once we learn to concentrate biomass and make it easily usable, it will be a great alternative to any of the other energy sources available today with the possible exception of nano-solar technology. Electricity biomass as an energy platform is definite a concept coming into its own.

We talked to North America's leading In Situ Leach (ISL) uranium mining engineers, and had them explain exactly how ISL worked. Most of the significant ISL operations in the United States were designed and/or constructed by these engineers. They explained how ISL mining is really just reversing the process of Mother Nature.


During ISL mining, water is pumped to the surface from production wells that contain uranium in very low concentrations, on the order of parts per million concentrations. The next step in the ISL process is to extract the uranium dicarbonate. Extraction is done by chemically exchanging ions inside a processing facility. "The ion exchange process is very analogous to a home Culligan

The Mystery Behind Saturn S Moon Enceladus

(category: Science, Word count: 442)
Share this article on: Facebook, Twitter, Whatsapp

The Cassini-Huygens exploration of Saturn, a seven-year joint venture of NASA, the European Space Agency, and the Italian Space Agency, is getting a closer look at its current subject of attention, the small moon of Enceladus. Enceladus is one of the most innermost moons of Saturn which scientists had assumed to be largely dead. With a very bright surface it reflects nearly 100 per cent of its heat and thereby has a very cold temperature, minus 330 degrees Fahrenheit.

A surprising discovery was that Enceladus, unlike nearby similar moon Mimas, is geologically active due to the emission of ice particles propelled by water vapor into the atmosphere from its south pole. Enceladus is a small moon of approximately 300 miles radius and the existence of any geological activity for a moon that size has scientists pleasantly baffled. Discovery of geological activity on any moon has been a rare phenomenon so far. The wonderful unexplained mystery behind Enceladus is the cause of the tremendous heat source that is warming the ice. Scientists can only guess that it is due to tidal activity or radioactive mechanisms for now.

At one time it was believed that the heat was being emitted from the mid-latitude tectonic gashes that circumscribe the south polar region. This was what Cassini's approach in July seemed to imply. However in contrast to that orbit of 286 miles, Cassini's more recent closer approach of 109 miles confirmed that the heat was actually being emitted from what are known as the tiger stripes of Cassini. The tiger stripes of Cassini are 80 mile long fissures running parallel to each other spaced about 25 miles apart. Cassini is only 314 miles across. The hottest spots were found in the south polar region of the tiger stripes.

Cassini determined there were two types of ice on Enceladus. An older amorphous variety was due to the constant characteristic of the surface of the planet. However the ice particles vented through the tiger stripe fissure were fine crystalline particles. This ice averaged ten microns in size. It is these tiny ice particles escaping the moon's atmosphere that are making up the composition of Saturn's broadest ring, the E ring.

In March of 2008, Cassini is scheduled to visit Enceladus again. Perhaps then more light will be shed on the mystery behind Enceladus.

Silver, a chemical element, exists in the periodic table with the symbol "Ag" and atomic number 47. Silver is a soft white lustrous transition metal. Due to the fact that it has the highest electrical and thermal conductivity of any metal, silver is widel used throughout the world, used in used in coins, jewelry, tableware, and photography. Silver occurs in minerals and in free form.

I'm sure if you looked you would have in your household several objects that are made of polished silver. For example: Silver dollars, or Silver cutlery, or photography equipment.

Being just a bit harder than gold, silver is very ductile and malleable. Because of silver's physical properties as a brilliant white metallic luster it can take a high degree of polish. Copper has replaced silver in several instances due to it's hire cost, this is especially true for electrical purposes.

Silver has a number of other notable characteristics:

- Silver has the whitest color of any metal

- Silver has the highest thermal conductivity of any metal

- Silver has the lowest contact resistance of any metal

- Silver has the highest optical reflectivity of any metal

Silver is stable in both pure air and water, but does tarnish when it is exposed to ozone, hydrogen sulfide, or air with sulfur in it. The most common use of silver is as a precious metal and its halide salts. This is especially true of silver nitrate. Silver is also widely used in photography, which has today, become the biggest single industry in which silver is used.

Metal detectors - When people think of Metal Detectors, some people think of combing a beach in search of coins or buried treasure while other people think of security, or the handheld scanners at a concert or sporting event.

Metal detector technology is a huge part of our everyday lives, with a range of uses that span from recreational activities to work and to safety. The metal detectors in airports, office buildings and prisons for example help ensure that no one is bringing a weapon onto the property. Consumer oriented metal detectors provide entertainment to people and give chance in discovering hidden treasures.

There are many different kinds and styles of metal detectors - gold detectors, coin and jewel detectors, beach-hunting detectors, underwater metal detectors, handheld and walk through metal detectors. Buying a metal detector can be complicated. Before deciding on a metal detector, there are a few points you should carefully consider.

Where it will be used?

Who will use it?

How often will it be put to use?

How much do metal detectors cost? Metal detectors range greatly in price... anywhere from $75.00 to all the way into the thousands. It's advisable to do your research thoroughly and find out which features you should be looking for when purchasing. Another option to consider would be purchasing a used metal detector. It is best to buy used metal detectors from a respected dealer as apposed to advertisements found in newspaper classifieds. Most dealers will not have the manufacturers warranty but will offer a money back guarantee or trade-in options.

By carefully examining your options you will be able to find a metal detector that is suitable for your needs without the need to dig deep unnecessarily.

Hubble Telescope

(category: Science, Word count: 528)

One of the most important telescopes in the history of astronomy, the Hubble telescope has allowed observers to peer farther into space than any previous telescope. By moving outside and above the atmosphere of the earth, the Hubble telescope has been able to observe visual data much more clearly than a terrestrial telescope, and it has been able to see much farther into the ultraviolet and infrared spectrums as well, since these spectra are largely absorbed by the earth's atmosphere. Thus, by moving the observing platform into open space, the Hubble telescope has given a much clearer view of the universe, allowing scientists to peer even deeper into space.

The Hubble telescope is named for Edwin Hubble, the astronomer who originally determined that the universe is expanding. This discovery, one of the foundations of modern astronomy and cosmology, made Hubble an excellent choice for the honor of having this telescope named for him.

The concept for the Hubble telescope was originally the idea of Lyman Spitzer back in 1946. He clearly saw that earth-based telescopes were inherently limited in their ability to see into the heavens, since dust, clouds, and even turbulence in the atmosphere interfered with telescopes' clarity. Which meant that the best way to get a clear image from a telescope was with a telescope that was in orbit around the earth.

After some success with the smaller Orbiting Astronomical Observatory, the plan for a large scale telescope was born. There were some fits and starts however, mostly due to budget constraints, and the project did not really take off until the 1970's and funding was not approved until 1978. Then, with funding in place, plans were made to launch the Hubble telescope in 1983. However, due to various delays, it was not actually launched until 1990.

After a few early problems, the Hubble telescope finally started sending back clear images. And those images were well worth the effort. The Hubble telescope was able to achieve a sharpness and resolution that was unimaginable with a standard, earth-bound telescope; crisp images that not only showed new detail in known areas of space, but also peered deeper into space than ever before. And with these new images, astronomers have been able to discover new and exciting information about our universe.

However, it is not only astronomers who have been amazed at the images that the Hubble telescope has produced. In fact, the images from Hubble are delights to view all on their own. From the clearly defined galaxies, to pictures of nebulae, to the Apollo 15 landing site, Hubble has been as exciting for the public as it has been for scientists.

As the Hubble telescope ages, its future is uncertain. Corrective software has allowed earth-based telescopes to pick up much of the information previously possible only with a space-based telescope. And as NASA retools itself to follow its mandate to take a man to Mars, money that would be spent on maintenance of the Hubble is being spent elsewhere. However, before the Hubble telescope enters the atmosphere sometime in 2010, it will provide a remarkable window into the universe and all that is in it.

Special Relativity Lite Simplified Version

(category: Science, Word count: 1636)
Share this article on: Facebook, Twitter, Whatsapp

Scales of critical attacks and remarks addressing the well-known theory of special relativity have recently acquired so imposing a scope that it is right to speak about an approaching crisis. Gradually to an increasing number of scientists, the numerous imperfections of this theory and the dead state of the scientific methodology introduced by it become apparent. Apparently, it is time to seriously upgrade STR and to subject it to corrective revision. With what is it necessary to begin?

In a rebuke to writers on STR, the fact was repeatedly put that they were really mathematicians rather than physicists. In building the theory, the formula of Lorentz's transformations already prevailed, and they tried "to adjust" reality to them. And as the selection had been initially made, all other alternatives "had been simply killed off and it had unwittingly blocked off a road to them. Thus, the deductive "mathematical" methodology prevailed.

Frankly, positivistic philosophical-methodological methods absolutizing the observer s position and denying availability of objective characteristics for natural subjects and other phenomena have also played a noxious role. Within the framework of a materialistic methodology, the situation when each of two observers moving past one another would fix alternative spatial and time reductions in the other system and thus would be right, never could be considered. The problem is natural to scientists gravitating to materialism in similar situations: and what takes place in these two systems actually? But instead of an answer, they here receive a positivistic-philosophical "fico": it appears, there is nothing actually; there is only one subjective semblance of the phenomena which is taken as the scientific basis.

So, two essential methodological defects which STR promoted created the deadlock observed today. Therefore, it is necessary for us to subject a problem within a relativistic situation to more stringent methodological analysis in which the path to the correct solution can be found.

Earlier, in the article "Relativity of Simultaneity Versus Other Relativistic Effects", we have already identified that creators of STR have demonstrated scandalous tendentiousness in the consideration of specific space-time relativistic effects. They have preferred relative reductions of lengths and reducing periods as main effects, and the effect of a relativity of simultaneity has

been pushed into the second plan, and presented in the capacity of being dependent on the first two. For this reason they designedly did not deduce the value of mistiming of clocks, basing the last effect, on the thought experiment with Einstein's train that would be quite natural and rather simple. Writers on STR have used this experiment qualitatively and the quantitative ratio was deduced later, after obtaining the formulas of Lorentz's transformations for space and time coordinates.

The outcome of this tendentious approach was that the effect of the relativity of simultaneity found itself in the backyard of STR and the methodological specificity introduced by it has remained scantily studied. There was a fatal error in it as will be exhibited below. The specific features introduced by this effect in a methodological situation, appear so considerable, that it causes a radical change in the attitude towards the problem.

It is considered that the effect of the relativity of simultaneity s "mistiming" of clocks lays in points along the line of relative motion for two moving systems. Formulas for the value of this mistiming are deduced in STR. However the importance of some details of mistiming for physics, in our opinion reflected badly on the theory. In our preceding article we attempted more deeply to uncover this situation.

Actually, the question is that in any points removed from each other along the line of relative motion of two systems, there is a relative distortion and a relative displacement of the time scale. We shall pay attention to the relative displacement. Clearly, in one of the systems, all events happening at any point removed from the origin of coordinates for two systems will happen with relative forestalling, and in other, accordingly, with relative delay. The value of this displacement demonstrates dependence on the relative velocity of the systems and the distances between the points along the line of motion.

It is important to realize that the indicated displacement occurs along the trajectory at the same time, changing from point to point. The question is about a new total factor in our time-space perception, a role and value which is very important to evaluate correctly! This total factor essentially distorts our customary cognitive methods. It is necessary to strain our space-time imagination a little to understand it.

The special situation generated by the relativity of simultaneity

Earlier, we had already drawn attention to the unforeseen problem generated by the effect of the relativity of simultaneity. If we combine the space-time origins of coordinates of two systems at any point (O=O`) then in all remaining points of the line of their relative motion, the relative displacement of the time scale will occur. In outcome synchronize in two systems those events which happen instantaneously in point O=O ` can only. In particular, only the instantaneous values of the vector quantities present at this point can be compared. All remaining events appear with some relative time-shift, and this fact of relative forestalling/delay is necessary for the relative comparison of the two systems. Actually these two systems demonstrate essential relative nonlinearity. Events meet in one point and then change along the x axis.

So, with solitary instantaneous events all is simple enough. And how would it be with a simultaneous comparison of two and more events occurring at miscellaneous points in space? Here appears a major problem. The factor of relative forestalling/delay of events in miscellaneous points makes the act of such comparison impossible in principle! What does this imply?

The classical act of measurement of spatial parameters implies simultaneous matching of the ends of a measured object with marks on a template. Clearly, that the effect of a relativity of simultaneity makes such classical act of direct measurement in a relativistic situation when the subject and a template are in two systems moving past one another, essentially impossible. We must look into this problem in detail. So, it is methodologically impossible, impermissible, to compare space segments directly in two systems! We have the same problem concerning time increments. Their direct comparison is also methodologically incorrect. All this results in the fact that direct comparison of any processes consisting of two and more events becomes impossible. In particular, it concerns any motion along any non-zero spatial segment or during any non-zero period.

And now let's recollect Michelson s experiment and the "strictly scientific" deduction of the well-known Lorentz's transformations on the basis of its results. In light of the problems found by us, the expectation of experimenters and theoretical-geometrical calculations of the creators of STR look at best, naive or ridiculous. The methodology, with which they were guided, is completely impermissible. It in mechanics of Newton one could join simultaneous processes of motion of a boat and a river (in the classical example of traversing a fast river) in one spatial drawing or a graphic diagram, and then get the resultant velocity from a right triangle. In relativistic mechanics, all this is impermissible! There can be no direct comparisons of spatial segments, periods and processes of motion, especially on one linear diagram! No direct comparisons of vectors spreading in the space and time, of right triangles composed of them and simple formulas of transformations! Specific relative space-time nonlinearity of the worlds, of the parallel flows of a development of events in two systems causes us to refuse former primitive methodological methods and to search for others (probably, indirect) methods of comparison. Events occur in the special time proportions in each of two flows, and the arbitrary transfer, mixing of formulas, and values of variable data are completely impermissible in these flows.

So, the correct methodology of direct comparisons does not exist and cannot exist in principle.

What then do the formulas of Lorentz's transformations offer us? Here, each of two moving experimenters independently (subjectively) makes a decision about what instants to consider as the beginning and the end of the act of measurement of a spatial segment or time period within the current process. But for all that, as it has been exhibited in our previous article, the solutions of the two experimenters contradict one another. Therefore it is no wonder that the results of such measurements are different. The situation where each experimenter considers that there are reductions of lengths of segments and periods in the other system is the effect of these subjective comparisons. Apparently, the cognitive value of similar comparisons and measurements is specifically subjective and comparable to the value of routine visual or acoustic illusions.

It is given that Lorentz's transformations are deduced from biased (non-objective) methodology and concern only private subjective – illusionary aspects of reality. They do not suit the extraneous objective observer. Watching for the meaningless measurements of two experimenters moving past one another and knowing about the absence of a correct methodology for direct comparisons, this observer should come inevitably to the conclusion that it is necessary to deny any statement about such comparisons in principle. And in the causes of the illusions of relative reductions, he needs to put forward a progressing relative displacement of the time scale along the line of relative motion of two systems. Then the point at issue will vanish. Then the absurd and irritating paradoxes, over the last hundred years will vanish also. In total, all of special relativity will be reduced to the one indicated phenomenon. Contrasted to the former version, the new special relativity theory appreciably wins in simplicity; therefore there is every reason to call it Special Relativity Lite.

Artificial Intelligence Is 50 Years Old

(category: Science, Word count: 497)

Artificial Intelligence as a research field was born in the summer of 1956 during a seminal workshop at Dartmouth College in Hanover, New Hampshire. It was just a year before that when Marvin Minsky, Nathaniel Rochester, Claude Shannon and John McCarthy proposed that they should hold a workshop to put together a roadmap about how to make machines think and learn similarly to humans. The ultimate goal was to discover computational models in order to enable machines to do commonsense reasoning. Today, John McCarthy is rightly considered the father of AI. I should note that the term "Artificial Intelligence" appeared for the first time in the proposal put forth by the previously mentioned scientists. And so this new discipline that would eventually captivate everyone's imagination was born.

Artificial Intelligence had its ups and downs in the last 50 years. Early success solving small problems in simulation ignited a flurry of predictions about super intelligent machines taking over the world before the coming of the 21st century. Hampered by a lack of a good understanding of how commonsense reasoning works in people and a lack of computational resources, computers being very slow up until the mid nineties, AI research stalled in the 80s. Many people rushed to dismiss it as nothing more than hot air.

However, science is all about proposing and testing new theories in order to find the best ones. Since the mid-90s, AI research has advanced by leaps and bounds. We now have a better understanding of how the human brain works and that has helped us to find and test better computational models for AI. These in turn have also helped us to better understand the functions of the human brain. New techniques such as statistical analysis are helping intelligent agents to copy with large amounts of information and noisy sensors. Faster computers with vast amounts of storage are allowing us to experiment in more challenging domains and solve larger problems.

It is true that AI has not yet been able to produce a machine capable of commonsense reasoning. However, by specialization, many AI systems are actually running our world today. AI helps us fly airplanes and drive our cars. It aids doctors perform surgery. It helps us find information in the vastness of the World Wide Web. It helps us discover spam email and promptly delete it. It helps us schedule traffic lights and public transportation. It helps us analyze financial markets and make predictions about the outcome of sports events. It aids in surveillance of public spaces improving security and safety. These are only a small sample of the penetration of intelligent systems in our daily lives. Artificial Intelligence is here to stay and I bet it won't be long before we have the understanding, methods and resources to finally construct thinking and learning machines. Let us wish and hope that such technology would only be used to benefit mankind and not destroy it.
