Liquid with power of light


Scientists bend liquid with power of light
Chicago, Mar 27 (AFP) A group of scientists have found a way to bend and direct liquid using only the force of light, according to a study that will be published Friday.

The French and American physicists used a laser beam to produce a surprisingly long and steady jet of soapy liquid that was narrower than a human hair. When directed at a different angle, it pushed the liquid into a hump-like shape.

It is believed to be the first time a laser had been used to generate bulk flow in fluids.

The discovery could lead to advances in biomedical and biotechnological research by offering a new way to control the flow of fluids through extremely narrow channels.

The discovery was made by accident while University of Chicago professor, Wendy Zhang, was visiting colleagues at the University of Bordeaux.

Zhang, who studies fluids, was invited into a lab where scientist Jean-Pierre Delville had observed a strange and unexpected result after completing a previous experiment involving the behavior of the same fluid under a less intense laser beam.

Delville turned up the laser power just to see what it could do, much the same way a motorist might test the performance of a powerful car on a deserted road.

"He turned up the power and then saw this amazing thing," Zhang said. "Because he has a lot of experience with optics, he realised that what he saw was strange." Zhang took the concept back to Chicago and started working out the theory of what happened with a graduate student, Robert Schroll, who is lead author of the study to be published in the Physical Review Letters on March 30.

First man to run around the world



Briton is first man to run around the world
London, Mar 27 (AFP) A British man was today officially certified by Guinness World Records as the first person to have run around the world.

Robert Garside, 40, said he was "so happy and relieved" after receiving his certificate in London as it had taken him nearly four years to fight claims that he had exaggerated his feat.

The self-described "Runningman" ran 56,000 kilometres across 30 countries, taking five years and eight months to complete his unprecedented journey.

Garside got more than just blisters and a certificate to show for his efforts.

"I met my wife on the run in Venezuela and she has been very supportive," he said.

In December 1996, Garside set out from Piccadilly Circus in the heart of London on his first attempt to jog around the world.

Then a 29-year-old psychology student, that attempt had to be abandoned when war broke out in Afghanistan.

It was only on his fourth try -- beginning at India Gate in New Delhi the following year -- that he succeeded, ending up back in the Indian capital in June 2003.

Since finishing in June 2003, the Briton has faced accusations that he was exaggerating his achievements and has spent the years since compiling evidence.

Marco Frigatti, Guinness's head of records, was convinced that Garside followed the rules.

His team ploughed though video footage, local news reports, credit card receipts and statements from witnesses saying Garside ran the route.

"It is genuine," Frigatti confirmed. (AFP)

God cannot exist

The concept of God

The concept of God
First a discussion of fundamental assumptions from which to derive an argument will be presented followed by an attempt to articulate a definition for the word God. Then the concept will be put to a critical evaluation in an attempt to confirm or refute it as representing an actual entity. I will be arguing that the concept of God has no cognitive content and that not only is the belief in a God irrational but that a God does not and indeed cannot exist. To prove that something does not exist all one has to do is prove that it cannot exist.

Assumptions

Assumption one: I proceed under the assumption that existence does indeed exist and that it possesses specific properties. Aristotle's law of identity (A is A) delineates the nature of these properties. It is an axiomatic principle from which logical laws and principles are derived. The law of identity states that something cannot be something else at the same time and in the same context. A is A and cannot be non-A at the same time and in the same context as it is A. A square circle cannot exist because it cannot be both at the same time and in the same respect. This means that there cannot exist a contradiction.

Assumption two: Consciousness is the process of perceiving reality. In an epistemological context, consciousness is axiomatic, but in a metaphysical context existence is axiomatic. In a metaphysical sense, to be conscious is necessarily to be conscious of something and this presumes that existence does exist and that it possesses specific properties. The significance of this distinction will become evident when we discuss the attributes of God.

Derivation: Since contradictions cannot exist we acknowledge logic as the final court of appeal. Logic is the art of non-contradictory identification. Logic rests on the axiomatic concept of existence existing and possessing specific properties. The law of identity's corollaries are delineated in texts on formal and informal logic. We will examine the concept of God with this assumption firmly established. We will test for internal contradictions as well as external contradictions. This means that we will apply logic to the attributes themselves as well as test for contradictions with the metaphysical primacy of existence.

Further assumption: We are examining the attributes of God under the assumption that they are intended to give us a coherent grasp of God's nature, and this is possible only if the attributes themselves are comprehensible. If they are unknowable, they are useless to us. The assertions that the theist makes with regard to their theory of God must be testable and knowable, otherwise it is useless to us and possesses no cognitive content.

Definition

Defining ones terms is a necessary preclusion to analyzing it. George Smith discusses the difficulty with defining the word God: "What, then, is meant by the word "god"? This is not a simple question. There have been many historical concepts of god, from the anthropomorphic deities of the Greeks to the omnipotent god of Christianity. Some gods are all powerful, all knowing and all good, while others are not. Some gods communicate with man, while others do not. Differences such as these make it impossible to give a detailed description of god that will encompass every religion--and secure widespread agreement on the meaning of "god" is a formidable, if not impossible, task.

Much of the confusion surrounding the idea of god stems from the fact that the word "god" is among the most abused terms in the history of man, ranking with such notorious words as "freedom," "justice" and "love". ... some people conveniently attach the word "god" to any belief with a tinge of significance, such as nature, the universe, love or an ultimate goal in ones life." [Smith;Atheism the Case Against God,31]

God may be fundamentally defined as a supernatural primary consciousness who is inherently unknowable and possesses three unlimited attributes: omnipotence, omniscience and omnibenevolence. These are the primary common denominators of most concepts of God and hence will comprise our definition of god. These attributes have been extracted from the writings of George Smith, philosopher of religion, and confirmed by introductory texts in philosophy.

The scope of this argument depends on ones acceptance of this definition. Any concept of God fundamentally defined as a supernatural being and/or as a primary consciousness is refuted by the following argument, if successful. Other concepts void of these attributes must be analyzed on their own terms.

It may be good to mention naturalistic theism since it is a trend in religious philosophy to identify God with nature. This would differ from our SUPERnatural God. These theists suggest that God is not above or beyond the natural universe but that he is omnipresent and indeed is the natural universe. George Smith has this to say of such a notion: "If one declared a belief in god, while stipulating that the term "god" was used as a synonym for the continent of North America, one's assertion would understandably be ignored or rejected as irrational. To expand this concept of god to include Europe, Asia, the planet Earth, our solar system--or the entire universe--is equally absurd." [Smith; Atheism the Case Against God,33] The theist thus obliterates the distinction between theism and atheism. The theist now makes no metaphysical assertion.

Smith makes an illustration as to show the importance of the supernatural element in the concept of God. "In another solar system, we discover an alien form of life, a form which is superior to man in all respects. These advanced creatures have an immense life span, superior strength, agility and mobility, and a superior capacity for memory and abstract thought. Does it follow, in virtue of these superior capacities, that these creatures should be designated as gods? No. Because despite the superiority of these creatures in relation to man, they are nevertheless bound by the natural laws of the universe. They are subject to the same physical and logical laws as man. If we did choose to call these beings "gods," this would mean that any creature who is superior to another creature thereby becomes a "god"--which would clearly lead to a chain of absurdities. A dog would be a god with respect to a plant. A man would be a god with respect to lower life forms. A genius would be a god in relation to a man of average intelligence, who would himself be a god when compared to a moron. ...In short, the difference between a god and natural existence must be a difference of kind, not merely of degree." [Smith; Atheism the Case Against God,37]

The supernatural being

The term supernatural has metaphysical connotations. It suggests that God is above or beyond the natural Universe. Theists rarely suggest that God exists in an actual place beyond the Universe because this is easily refuted deductively by the constituent definitions of "Universe" and "Beyond", they more often suggest that he exists without being subject to causal law and the law of identity. The term also has epistemological connotations. Epistemologically this would put God beyond human understanding. Unknowability is derived directly from the concept of the supernatural.

To exist beyond the framework of causal laws would be to exist beyond existence. This is derived directly from our first assumption. Existence by definition encompasses all that is. There is no alternative to existence ("non-existence is not a fact it is the absence of a fact." [Rand;IOE]). "To be is to be something as opposed to nothing, and to be something is to be something specific. If a God is to have any characteristics (which it must to exist), these characteristics must be specific but to assign definite attributes, to say that a being is this as opposed to that, is to limit the capacities of that being and to subject it to the uniformity imposed by those capacities. A supernatural being, if it is to differ in kind from natural existence, must exist without a limited nature-which amounts to existence without any nature at all."[Smith; Atheism the Case Against God,41] Further, deriving from our first assumption that existence possesses a specific identity which it is necessarily limited to a being who exists without a nature (identity) is to exist without existing. To exist without existing is to commit ones self to a contradiction. Therefor the concept of a supernatural being is inherently contradictory. This renders the notion invalid and void of cognitive content.

The primary Consciousness

The theist asserts that God is Metaphysically primary or axiomatic. God is said to be omnipresent and that his existence is his essence and vise versa. God's essence and existence are said to be indistinguishable because they are one in the same. "essence" refers to what a thing is; "existence" refers to that a thing is. The essence--existence dichotomy applies to every being except God because he is not made of component parts. The bible says that "I AM WHO I AM" is the only adequate answer to "what is God?". If we cannot distinguish the essence of God and his existence then we cannot distinguish him at all since man comprehends in terms of essence and existence. If we cannot apply these categories to God then we cannot comprehend him. As you will recall we derived incomprenceability from the supernatural element as well. The concept of a supernatural being and a primary consciousness both go to my thesis that the concept of God has no cognitive content. With every attribute that the theist proposes they fling themselves farther into agnosticism which is a branch of atheism.

If one is conscious, one exists. If one exists then one is subject to the law of identity. If ones consciousness is subject to the law of identity then it cannot be primary or axiomatical because it presumes that it exists and has an identity. The concept of a primary consciousness is inherently contradictory hence it cannot exist.

The inherantly Unknowable Being

God is said to be unknowable or incomprehensible. This is stated explicitly in many source as well as derived from other fundamental attributes of God. If God is Different in kind from natural existence then he is unknowable and if God is unknowable then the theist's claim to have knowledge of God is an impossibility. If God does not exist then we could have no knowledge of him and if God does exist, we again could have no knowledge of him. This unfalsifiable element makes the attribute useless and again adds no cognitive content to the concept of God.

The Omni Attributes

To exist is to be. To be is to be something. To be something is to be something specific, possessing specific properties. The omni attribute is defined as totally unlimited. This analysed with the primacy of existence demonstrates that an omniattribute cannot exist. An entity must be limited to it's identity. While the concept of a metaphysical infinite is a potentiality, epistemologically it remains an impossibility. The theist suggests that God exists without a particular nature which means that he has no nature at all, which means that he is different in kind from the natural universe which makes him incomprehensible or that it simply cannot exist. these are the only two options that can be derived from this attribute and both lead to zero cognitive content.

Omnipotence

There can be no obstacle to an omnipotent being, no difficulties that God must overcome. The necessity of employing means to accomplish an end is the consequence of limited power (or an identity, as we have seen). Therefore God cannot be said to employ means in any sense. God cannot be said to act in any manner because an action is required by a being that employs means to an end. Nor can God be said to have a purpose because purpose presumes an unattained end.

Omniscience

God is said to know the past, present and the futer infallibly and absolutely. If God or any other being knows the futer then that would mean that the futer is predetermined. without volition the concept of salvation is a farce. People would have no choice as to what they believe. The theist trys to side step this dilemma by stating that God does not impose his foreknowledge on the course of events but this does not change the fact that if one knows what will happen then it must happen. If God knows without fallibility the futer he cannot be omnipotent. If he can change the course of events he cannot have infallible knowledge of the futer, hence he cannot be omniscient.

Omnibenevlence

Obviously there is what we would call evil in the world such as murder or rape for example. If the theist claims that our concept of good and evil is invalid and Gods is the only appropriate one that is unknowable then the theists claim that God is good is equally invalid.

To be benevolent there must be a choice between good and evil. If God chooses to do evil over good and he has total power he would be immoral. If God does not know there is evil but cannot prevent it he cannot be omnipotent. If God knows there is evil and can prevent it but chooses not to he cannot be omnibenevolent.

Final Note On Omni Attributes

If God knows there is evil and can stop it but chooses not to be cannot be omnibenevolent. If God knows there is evil and cannot stop it then he cannot be omnipotent. If God does not know there is evil then he cannot be omniscient.

Summery

No attribute of God can hold up to a critical evaluation. Every attribute of the concept of God has been found to be either internally inconsistent or in contradiction to the fundamental primacy of existence. The concept here discussed adds no cognitive content to the word God. We have demonstrated that God cannot exist hence does not exist.

Alcohol, Tobacco Worse Than Drugs

Study: Alcohol, Tobacco Worse Than Drugs

By MARIA CHENG
The Associated Press
Friday, March 23, 2007; 3:41 AM

LONDON -- New "landmark" research finds that alcohol and tobacco are more dangerous than some illegal drugs like marijuana or Ecstasy and should be classified as such in legal systems, according to a new British study.

In research published Friday in The Lancet magazine, Professor David Nutt of Britain's Bristol University and colleagues proposed a new framework for the classification of harmful substances, based on the actual risks posed to society. Their ranking listed alcohol and tobacco among the top 10 most dangerous substances.

AIDS/HIV AIDS/HIV
Twenty-five years after the first diagnosis of the first case of AIDS, the world is waking up to the epidemic.

Bird Flu Focus on Bird Flu
Track the latest developments in the spread of the deadly H5N1 influenza virus.
Nutt and colleagues used three factors to determine the harm associated with any drug: the physical harm to the user, the drug's potential for addiction, and the impact on society of drug use. The researchers asked two groups of experts _ psychiatrists specializing in addiction and legal or police officials with scientific or medical expertise _ to assign scores to 20 different drugs, including heroin, cocaine, Ecstasy, amphetamines, and LSD.

Nutt and his colleagues then calculated the drugs' overall rankings. In the end, the experts agreed with each other _ but not with the existing British classification of dangerous substances.

Heroin and cocaine were ranked most dangerous, followed by barbiturates and street methadone. Alcohol was the fifth-most harmful drug and tobacco the ninth most harmful. Cannabis came in 11th, and near the bottom of the list was Ecstasy.

According to existing British and U.S. drug policy, alcohol and tobacco are legal, while cannabis and Ecstasy are both illegal. Previous reports, including a study from a parliamentary committee last year, have questioned the scientific rationale for Britain's drug classification system.

"The current drug system is ill thought-out and arbitrary," said Nutt, referring to the United Kingdom's practice of assigning drugs to three distinct divisions, ostensibly based on the drugs' potential for harm. "The exclusion of alcohol and tobacco from the Misuse of Drugs Act is, from a scientific perspective, arbitrary," write Nutt and his colleagues in The Lancet.

Tobacco causes 40 percent of all hospital illnesses, while alcohol is blamed for more than half of all visits to hospital emergency rooms. The substances also harm society in other ways, damaging families and occupying police services.

Nutt hopes that the research will provoke debate within the UK and beyond about how drugs _ including socially acceptable drugs such as alcohol _ should be regulated. While different countries use different markers to classify dangerous drugs, none use a system like the one proposed by Nutt's study, which he hopes could serve as a framework for international authorities.

"This is a landmark paper," said Dr. Leslie Iversen, professor of pharmacology at Oxford University. Iversen was not connected to the research. "It is the first real step towards an evidence-based classification of drugs." He added that based on the paper's results, alcohol and tobacco could not reasonably be excluded.

"The rankings also suggest the need for better regulation of the more harmful drugs that are currently legal, i.e. tobacco and alcohol," wrote Wayne Hall, of the University of Queensland in Brisbane, Australia, in an accompanying Lancet commentary. Hall was not involved with Nutt's paper.

While experts agreed that criminalizing alcohol and tobacco would be challenging, they said that governments should review the penalties imposed for drug abuse and try to make them more reflective of the actual risks and damages involved.

Nutt called for more education so that people were aware of the risks of various drugs. "All drugs are dangerous," he said. "Even the ones people know and love and use every day."

NOTHING IS IMPOSSIBLE.. .

NOTHING IS IMPOSSIBLE.. .

My name is Nick Vujicic and I give God the Glory for how He has used my testimony to touch thousands of hearts around the world! I was born without limbs and doctors have no medical explanation for this birth "defect". As you can imagine, I was faced with many challenges and obstacles.
"Consider it pure joy, my Brothers, whenever you face trials of many kinds."
....To count our hurt, pain and struggle as nothing but pure joy? As my parents were Christians, and my Dad even a Pastor of our church, they knew that verse very well. However, on the morning of the 4th of December 1982 in Melbourne (Australia), the last two words on the minds of my parents was "Praise God!". Their firstborn son had been born without limbs! There were no warnings or time to prepare themselves for it. The doctors we shocked and had no answers at all! There is still no medical reason why this had happened and Nick now has a Brother and Sister who were born just like any other baby.
The whole church mourned over my birth and my parents were absolutely devastated. Everyone asked, "if God is a God of Love, then why would God let something this bad happen to not just anyone, but dedicated Christians?" My Dad thought I wouldn't survive for very long, but tests proved that I was a healthy baby boy just with a few limbs missing.

Understandably, my parents had strong concern and evident fears of what kind of life I'd be able to lead. God provided them strength, wisdom and courage through those early years and soon after that I was old enough to go to school.

The law in Australia didn't allow me to be integrated into a main-stream school because of my physical disability. God did miracles and gave my Mom the strength to fight for the law to be changed. I was one of the first disabled students to be integrated into a main-stream school.

I liked going to school, and just try to live life like everyone else, but it was in my early years of school where I encountered uncomfortable times of feeling rejected, weird and bullied because of my physical difference. It was very hard for me to get used to, but with the support of my parents, I started to develop attitudes and values which helped me overcome these challenging times. I knew that I was different but on the inside I was just like everyone else. There were many times when I felt so low that I wouldn't go to school just so I didn't have to face all the negative attention. I was encouraged by my parents to ignore them and to try start making friends by just talking with some kids. Soon the students realized that I was just like them, and starting there God kept on blessing me with new friends.

There were times when I felt depressed and angry because I couldn't change the way I was, or blame anyone for that matter. I went to Sunday School and learnt that God loves us all and that He cares for you. I understood that love to a point as a child, but I didn't understand that if God loved me why did He make me like this? Is it because I did something wrong? I thought I must have because out of all the kids at school, I'm the only weird one. I felt like I was a burden to those around me and the sooner I go, the better it'd be for everyone. I wanted to end my pain and end my life at a young age, but I am thankful once again, for my parents and family who were always there to comfort me and give me strength.

Due to my emotional struggles I had experienced with bullying, self esteem and loneliness, God has implanted a passion of sharing my story and experiences to help others cope with whatever challenge they have in their life and let God turn it into a blessing. To encourage and inspire others to live to their fullest potential and not let anything get in the way of accomplishing their hopes and dreams.

One of the first lessons that I have learnt was not to take things for granted.



"And we know that in all things God works for the best for those who love Him."
That verse spoke to my heart and convicted me to the point where that I know that there is no such thing as luck, chance or coincidence that these "bad" things happen in our life.
I had complete peace knowing that God won't let anything happen to us in our life unless He has a good purpose for it all. I completely gave my life to Christ at the age of fifteen after reading John 9. Jesus said that the reason the man was born blind was "so that the works of God may be revealed through Him." I truly believed that God would heal me so I could be a great testimony of His Awesome Power. Later on I was given the wisdom to understand that if we pray for something, if it's God's will, it'll happen in His time. If it's not God's will for it to happen, then I know that He has something better.
I now see that Glory revealed as He is using me just the way I am and in ways others can't be used.

I am now twenty-one years old and have completed a Bachelor of Commerce majoring in Financial Planning and Accounting. I am also a motivational speaker and love to go out and share my story and testimony wherever opportunities become available. I have developed talks to relate to and encourage students through topics that challenge today's teenagers. I am also a speaker in the corporate sector.

I have a passion for reaching out to youth and keep myself available for whatever God wants me to do, and wherever He leads, I follow.

I have many dreams and goals that I have set to achieve in my life. I want to become the best witness I can be of God's Love and Hope, to become an international inspirational speaker and be used as a vessel in both Christian and non-Christian venues. I want to become financially independent by the age of 25, through real estate investments, to modify a car for me to drive and to be interviewed and share my story on the "Oprah Winfrey Show"! Writing several best-selling books has been one of my dreams and I hope to finish writing my first by the end of the year. It will be called "No Arms, No Legs, No Worries!"

I believe that if you have the desire and passion to do something, and if it's God's will, you will achieve it in good time. As humans, we continually put limits on ourselves for no reason at all! What's worse is putting limits on God who can do all things. We put God in a "box". The awesome thing about the Power of God, is that if we want to do something for God, instead of focusing on our capability, concentrate on our availability for we know that it is God through us and we can't do anything without Him. Once we make ourselves available for God's work, guess whose capabilities we rely on? God's! ? No - Its the strenghth of ur ......
