"WE DON'T know what we are talking about" - Nobel Laureate David Gross

Last December ('05), physicists held the 23rd Solvay Conference in Brussels, Belgium. Amongst the many topics covered in the conference was the subject matter of string theory. This theory combines the apparently irreconcilable domains of quantum physics and relativity. David Gross a Nobel Laureate made some startling statements about the state of physics including: "We don't know what we are talking about" whilst referring to string theory as well as "The state of physics today is like it was when we were mystified by radioactivity."

The Nobel Laureate is a heavyweight in this field having earned a prize for work on the strong nuclear force and he indicated that what is happening today is very similar to what happened at the 1911 Solvay meeting. Back then, radioactivity had recently been discovered and mass energy conservation was under assault because of its discovery. Quantum theory would be needed to solve these problems. Gross further commented that in 1911 "They were missing something absolutely fundamental," as well ar "we are missing perhaps something as profound as they were back then."

Coming from a scientist with establishment credentials this is a damning statement about the state of current theoretical models and most notably string theory. This theoretical model is a means by which physicists replace the more commonly known particles of particle physics with one dimensional objects which are known as strings. These bizarre objects were first detected in 1968 through the insight and work of Gabriele Veneziano who was trying to comprehend the strong nuclear force.

Whilst meditating on the strong nuclear force Veneziano detected a similarity between the Euler Beta Function, named for the famed mathematician Leonhard Euler, and the strong force. Applying the aforementioned Beta Function to the strong force he was able to validate a direct correlation between the two. Interestingly enough, no one knew why Euler's Beta worked so well in mapping the strong nuclear force data. A proposed solution to this dilemma would follow a few years later.

Almost two years later (1970), the scientists Nambu, Nielsen and Susskind provided a mathematical description which described the physical phenomena of why Euler's Beta served as a graphical outline for the strong nuclear force. By modeling the strong nuclear forces as one dimensional strings they were able to show why it all seemed to work so well. However, several troubling inconsistencies were immediately seen on the horizon. The new theory had attached to it many implications that were in direct violation of empirical analyses. In other words, routine experimentation did not back up the new theory.

Needless to say, physicists romantic fascination with string theory ended almost as fast as it had begun only to be resuscitated a few years later by another 'discovery.' The worker of the miraculous salvation of the sweet dreams of modern physicists was known as the graviton. This elementary particle allegedly communicates gravitational forces throughout the universe.

The graviton is of course a 'hypothetical' particle that appears in what are known as quantum gravity systems. Unfortunately, the graviton has never ever been detected; it is as previously indicated a 'mythical' particle that fills the mind of the theorist with dreams of golden Nobel Prizes and perhaps his or her name on the periodic table of elements.

But back to the historical record. In 1974, the scientists Schwarz, Scherk and Yoneya reexamined strings so that the textures or patterns of strings and their associated vibrational properties were connected to the aforementioned 'graviton.' As a result of these investigations was born what is now called 'bosonic string theory' which is the 'in vogue' version of this theory. Having both open and closed strings as well as many new important problems which gave rise to unforeseen instabilities.

These problematical instabilities leading to many new difficulties which render the previous thinking as confused as we were when we started this discussion. Of course this all started from undetectable gravitons which arise from other theories equally untenable and inexplicable and so on. Thus was born string theory which was hoped would provide a complete picture of the basic fundamental principles of the universe.

Scientists had believed that once the shortcomings of particle physics had been left behind by the adoption of the exotic string theory, that a grand unified theory of everything would be an easily ascertainable goal. However, what they could not anticipate is that the theory that they hoped would produce a theory of everything would leave them more confused and frustrated than they were before they departed from particle physics.

The end result of string theory is that we know less and less and are becoming more and more confused. Of course, the argument could be made that further investigations will yield more relevant data whereby we will tweak the model to an eventual perfecting of our understanding of it. Or perhaps 'We don't know what we are talking about.'

The Bio-Ethanol Fuel Dilemma - A Qualitative Research

ABSTRACT

Bio-fuels are non-fossil fuels, produced from agriculture sources, residues, and waste. Bio-ethanol refers to ethanol produced from crops (e.g., corn-ethanol and sugar-ethanol) and from waste (i.e., biomass-ethanol). "The motivation for developing bio-ethanol as a transportation fuel is based on concerns about energy security, environmental quality, economic competitiveness, and stabilization of the agricultural sector." (National Research Council [NRC], 1999, p. 6) Brazil's three-decade experience in sugarcane-ethanol is considered a success by its government, although criticized by some researchers (Pimentel, 2001; Pimentel et al., 2002). Corn-ethanol production in North America is highly controversial; its cost, its energy balance, and its socio-economical effects are strongly debated between researchers. Biomass-ethanol, produced from farm and municipality waste is still in its early technological and industrial development. This quantitative research presents and analyzes the arguments, and concludes with recommendations for the short- and the long-term; recommendations that are best suited? for North America and that take into account all the aspects presented in this research paper.

Corn-ethanol is not expected, and will never replace the fossil-gasoline consumption in North America, but could only be an alternative for up-to-fifteen percents at most: "increased production of ethanol from corn is a low-risk, viable short term solution" (Herwick & Wheeler, 2005, p. 28). Biomass-ethanol, in contrast to corn-ethanol, could be "an effective strategy for displacing petroleum…. Ultimately, producing ethanol from biomass will be more cost effective and necessary to achieve significant volume…. In total, 66B [billion] to 107B gallon of ethanol could be produced annually from [all sources of] biomass: it would be sufficient to support E60 to E70 [i.e., 60 to 70 percent of liquid fuel consumption], [and] displace approximately half of the petroleum used" (Herwick & Wheeler, 2005, pp. 27-28). Nevertheless, the technology for economical production of biomass-ethanol is still in early development, and President George W. Bush's pledge, in his January 29th, 2006, State of the Union Address "to fund the research on cutting-edge methods of producing [biomass] ethanol" (Energy Policy Act, 2005; U.S. Energy Bill, 2005) is key to achieving the goal of producing 7.5 billion gallons of bio-ethanol in 2015.

Addressing the problem of energy crisis in general, the 2005 symposium concludes that "the reality is that we can no longer just drill our way to global energy security. We must innovate our way to energy security- we must find new technologies that uncover new fossil energy sources, that conserve energy, that protect the environment, and that provide multiple, sustainable sources of energy." (National Academy of Engineering [NAE], 2006, p. 163)

CONCLUSIONS

Current corn-ethanol production methods use a significant amount of energy; by using alternative sources as energy inputs (other than petroleum) in the ethanol conversion, the net energy balance of corn-ethanol would be positive. When we include externalities, the ethanol energy balance would even outperform that of petroleum-based liquid fuel. Assessing all the factors, the corn-ethanol has overall positive economical cost/benefit value. The social aspects of corn-ethanol, as discussed in this paper, emphasize the possible risks, and their negative impacts on rural North America – some of which are irreversible – and local farmers should be educated about them, before they have jumped on the wagon and it is too late. The moral aspects of agriculture-for-fuel are a real concern, but as long as other products (e.g., tobacco) are grown freely in third-world countries, the argument cannot touch ordinary North Americans. The U.S. and Canadian federal governments, as well as state and provincial governments, should keep the current (relatively low) level of subsidies (i.e., 52 cents for a gallon of pure ethanol, in the US), along with fuel-tax removal – this is more or less the cost of oil's externalities. Providing low-interest long-term loans to farmers, for the construction of ethanol plants, will not cost much to the tax payers, but will enable those farmers who have excess yield of corn to receive more value for it.

However, corn growth in North America is limited, by means of land. From the total of about ten billion bushels of corn grown in the US, only 25 billion gallons of ethanol could be produced, out of 140 billion gasoline consumed annually; therefore, corn-ethanol will never replace the petroleum liquid fuel in the US (Herwick & Wheeler, 2005, p. 7); corn-ethanol can, at highest production, provide solutions to E10 (or to E15) blends in the US. The Canadian supply of corn (and corn-ethanol) will have a very limited impact on the North American market, and will not significantly change the conclusion above.

Biomass is a great source of renewable liquid fuel, and has the potential of replacing up to half of the petroleum fuel consumed in North America. The major obstacle for reaching that goal is technology related; we need to develop an efficient conversion process, one that is cost effective and consumes less energy, and at the same time produces food- and feed-byproducts. For achieving this goal, the U.S. federal government must invest heavily in research and development.

For the long term, the solution to transportation fuel crisis should focus on fuel efficiency and reduction of fuel consumption, along with diversification of fuel sources, as concludes a symposium by National Academy of Engineering: "the reality is that we can no longer just drill our way to global energy security. We must innovate our way to energy security- we must find new technologies that uncover new fossil energy sources, that conserve energy, that protect the environment, and that provide multiple, sustainable sources of energy."

E=mc2 is Wrong - Einstein's Special Relativity Fundamentally Flawed

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.

A Bird's-Eye View of Wolves

Wolves are a widely studied species in Yellowstone. Since wolves were reintroduced to the park after an absence of almost 80 years, scientists spend a lot of time studying the animals' unique behavior.

"Our knowledge of wolves is vast due to decades of research around the world," said Tom Oliff, chief of natural resources. "The ability to oversee wolves in the wild has been challenging and the knowledge gained through direct observations of behavior is invaluable to understanding the species."

The best way to study wolf movement is from the air. The Raven's Eye View of Yellowstone is a component of the Aerial Eyes project that is supported by Yellowstone Park Foundation (www.ypf.org) in cooperation with Canon U.S.A. The Eyes on Yellowstone program is made possible by Canon; it provides funding and digital technology to support an array of park resource management and education programs.

Using a Canon EOS 20D digital camera body with a 100-400EF lens (f 4.5-5.6) as a scientific tool, wolf biologists Doug Smith and Dan Stahler are changing the way quantitative and qualitative wolf data are gathered and studied.

The scientists have documented various behavior-from hunting prey, to raising pups, to interacting with various species throughout the park. The details, however, remain difficult to see with the naked eye, particularly when using the routine monitoring technique of aerial radio tracking from fixed-wing aircraft flying high overhead.

The digital equipment has helped revolutionize this research. High-resolution digital photographs that can be taken several hundred feet above ground and later enhanced have, in a short time, opened new windows to studying wolf ecology and behavior.

"This is a major breakthrough for wolf research, providing first-of-its-kind results," said Stahler. "Of particular value is the identification of individual wolves and the role each plays in the pack while engaged in different activities. Determining the presence and number of pups in a litter, or whether or not a certain member of the pack is still alive, can now be readily discernable through studying photographs taken with quality digital camera equipment."

Digital photography has changed science, and it has allowed Yellowstone scientists to gather data never obtained by any other wolf research project. The combination of digital imaging and enhanced lens quality are key scientific tools to help study and understand wolves.
