&lt;P&gt;This is probably in my top 5 stupid things that I have ever done.&lt;/P&gt;

&lt;P&gt;I'm going to hell.&amp;nbsp; Pesky christians lured me in with a hot chick and how was I supposed to know about this no sex before marriage nonsense.&amp;nbsp; Apparently getting drunk is frowned upon too.&amp;nbsp; Not for me!&lt;/P&gt;

&lt;TD&gt;&lt;PRE&gt;&lt;TT&gt;&lt;SMALL&gt;&lt;FONT face=Verdana size=1&gt;we were on our way to a club and the pic on drivers ID was 
not the same person as the driver, the driver couldnt 
speak spanish and didnt know where the club was.

i told him to pull over so my friend can throw up. we all 
got out and i told them to run away.

then i gave the guy 2 pesos and said thanks. 

i told him that the pic wasnt him and he reached into his 
glove box and pulled out a gun.

i ran and he drove off and abused me.

all thats all i guess.

bye bye

&lt;P&gt;Yes, they had actually picked the car up in their hands and put it in the grass next to the lake.&amp;nbsp; It was funny at first, until I realised that some fucker had called the ass munch council and the fucking fuckers sent&amp;nbsp;some dildo licker mofo to give me a £40 parking ticket.&lt;/P&gt;
&lt;P&gt;I called&amp;nbsp;the police and they didn't answer for 20 mins so I hung up.&amp;nbsp; I called the police again later and they told me that no crime had been comitted as there was no damage to my car.&amp;nbsp; I told them that a £40 ticket is damage to my wallet either way and they said, "Are you sure you didn't park your car there?!".&amp;nbsp; I really wanted to fucking kill that fucking pig.&amp;nbsp; Well, I've got better things to do to than to bend over and take one from the system and old people who make complaints to the council about cars parked in fields.&amp;nbsp; Fucking shit licking gerbil arse fisters.&amp;nbsp; Unfortunately, there seems to be fuck all I can do about it.&lt;/P&gt;
&lt;P&gt;My car is jinxed.&amp;nbsp; It has broken down like clockwork every month for the past few years.&amp;nbsp; The petrol cap broke last week.&amp;nbsp; The windscreen wipers fell off the week before.&amp;nbsp; Slow puncture the week before that.&amp;nbsp; Little things, but very annoying... a bit like Hanson.&lt;/P&gt;

&lt;P&gt;A girl at work somehow found the site and then proceeded to tell everyone about it.&amp;nbsp; I did express to her that I didn't want anyone else to know about it, but she ignored my request.&lt;/P&gt;
&lt;P&gt;Much of what I had to delete and hide on this site was related to the fact that I was romantically involved with a girl from work, who I should not have been involved with.&amp;nbsp; It came to the point that her boyfriend found out and came in to our office and expressed his anger.&amp;nbsp; To make it worse, he had to come into the office everyday to pick up the mail from us as he was the postman.&lt;/P&gt;
&lt;P&gt;I left work shortly after this one day at lunchbreak and didn't go back.&amp;nbsp; I couldn't bear to work with the girl when it finished and I couldn't bear to look her boyfriend in the eye without feeling like a complete bastard.&amp;nbsp; My boss was very understanding, but&amp;nbsp;did an excellent job of trying to get me back to work.&lt;/P&gt;
&lt;P&gt;So!&amp;nbsp; I had&amp;nbsp;a pretty shite Christmas.&amp;nbsp; I lost my: job, a girl and my car broke down.&lt;/P&gt;
&lt;P&gt;(Currently watching the music video by Boogie Pimps - Somebody to love.&amp;nbsp; I highly reccomend it.)&lt;/P&gt;
&lt;P&gt;Harmony Star (check out her xanga site) came to stay with me for a couple of days at Christmas.&amp;nbsp; It was the first time that we had met.&amp;nbsp; I was relieved that she was neither weird nor boring.&amp;nbsp; She had Christmas day lunch with my family and they all thought she was lovely.&amp;nbsp; She is lovely and I was sad that she didn't stay with us for long.&amp;nbsp; I also felt a bit bad for not planning any fun activities for us to do other than drinking.&amp;nbsp; I really didn't think she would turn up.&amp;nbsp; I mean she came all the way from Australia, surely there are more important people to visit than me, like ... The Queen or Bill Oddie.&lt;/P&gt;
&lt;P&gt;You may remember that I had glandular fever at the end of last year.&amp;nbsp; I had a one night stand with a girl called Roisin that I regretted muchily.&amp;nbsp; She saw me in the street by chance a few weeks ago and gave me her new mobile number and asked me to call her.&amp;nbsp; So I did.&amp;nbsp; I have never met a girl as strange as her.&amp;nbsp; It turns out that she actually is schitzophrenic.&amp;nbsp; Sometimes I think that I am flypaper for all the wrong girls.&lt;/P&gt;
&lt;P&gt;I really wish that I could meet a girl that is:&amp;nbsp;single, doesn't suffer from anorexia or bulemia, doesn't suffer from any kind of mental illness for that matter and who has a strong sex drive.&amp;nbsp; Is this too much to ask?!&amp;nbsp; Of course they must fulfill all the regular pre-requisites: attractive, intelligent, smells nice, middle class and likes my pet snakes.&lt;/P&gt;
&lt;P&gt;I am currently training to be a plumber!&amp;nbsp; Nigh is the end to working in an office glued to a computer and a telephone.&amp;nbsp; I am really looking forward to this completely new career.&lt;/P&gt;
&lt;P&gt;If you are reading this and you do know me, please do not distribute the web address to everyone.&amp;nbsp; I would appreciate it.&lt;/P&gt;</description><comments>http://www.xanga.com/BiG_SCaR_BRuCe/58140994/item.html#firstcomment</comments></item><item><title>Wednesday, December 03, 2003</title><link>http://www.xanga.com/BiG_SCaR_BRuCe/47333005/item.html</link><guid>http://www.xanga.com/BiG_SCaR_BRuCe/47333005/item.html</guid><pubDate>Wed, 03 Dec 2003 12:54:08 GMT</pubDate><description>&lt;P align=justify&gt;Quantum physics predicts the existence of an underlying sea of zero-point energy at every point in the universe. This is different from the cosmic microwave background and is also referred to as the electromagnetic quantum vacuum since it is the lowest state of otherwise empty space. This energy is so enormous that most physicists believe that even though zero-point energy seems to be an inescapable consequence of elementary quantum theory, it cannot be physically real, and so is subtracted away in calculations. &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;A minority of physicists accept it as real energy which we cannot directly sense since it is the same everywhere, even inside our bodies and measuring devices. From this perspective, the ordinary world of matter and energy is like a foam atop the quantum vacuum sea. It does not matter to a ship how deep the ocean is below it. If the zero-point energy is real, there is the possibility that it can be tapped as a source of power or be harnassed to generate a propulsive force for space travel. &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;The propellor or the jet engine of an aircraft push air backwards to propel the aircraft forward. A ship or boat propellor does the same thing with water. On Earth there is always air or water available to push against. But a rocket in space has nothing to push against, and so it needs to carry propellant to eject in place of air or water. The fundamental problem is that a deep space rocket would have to start out with all the propellant it will ever need. This quickly results in the need to carry more and more propellant just to propel the propellant. The breakthrough one wishes for deep space travel is to overcome the need to carry propellant at all. How can one generate a propulsive force without carrying and ejecting propellant? &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;There is a force associated with the electromagnetic quantum vacuum: the Casimir force. This force is an attraction between parallel metallic plates that has now been well measured and can be attributed to a minutely tiny imbalance in the zero-point energy in the cavity between versus the region outside the plates. This is not useful for propulsion since it symmetrically pulls on the plates. However if some asymmetric variation of the Casimir force could be identified one could in effect sail through space as if propelled by a kind of quantum fluctuation wind. This is pure speculation. &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;The other requirement for space travel is energy. A thought experiment published by physicist Robert Forward in 1984 demonstrated how the Casimir force could in principle be used to extract energy from the quantum vacuum (&lt;A href="http://www.calphysics.org/articles/Forward1984.pdf" target="_new"&gt;Phys. Rev. B, 30, 1700, 1984&lt;/A&gt;). Theoretical studies in the early 1990s (&lt;A href="http://www.calphysics.org/articles/CP93.pdf" target="_new"&gt;Phys. Rev. E, 48, 1562, 1993&lt;/A&gt;) verified that this was not contradictory to the laws of thermodynamics (since the zero-point energy is different from a thermal reservoir of heat). Unfortunately the Forward process cannot be cycled to yield a continuous extraction of energy. A Casimir engine would be one whose cylinders could only fire once, after which the engine become useless. &lt;FONT face=verdana color=maroon size=2 ,&gt;
&lt;P align=justify&gt;ORIGIN OF ZERO-POINT ENERGY &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;The basis of zero-point energy is the Heisenberg uncertainty principle, one of the fundamental laws of quantum physics. According to this principle, the more precisely one measures the position of a moving particle, such as an electron, the less exact the best possible measurement of momentum (mass times velocity) will be, and vice versa. The least possible uncertainty of position times momentum is specified by Planck's constant, h. A parallel uncertainty exists between measurements involving time and energy. This minimum uncertainty is not due to any correctable flaws in measurement, but rather reflects an intrinsic quantum fuzziness in the very nature of energy and matter. &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;A useful calculational tool in physics is the ideal harmonic oscillator: a hypothetical mass on a perfect spring moving back and forth. The Heisenberg uncertainty principle dictates that such an ideal harmonic oscillator -- one small enough to be subject to quantum laws -- can never come entirely to rest, since that would be a state of exactly zero energy, which is forbidden. In this case the average minimum energy is one-half h times the frequency, hf/2. &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;Radio waves, light, X-rays, and gamma rays are all forms of electromagnetic radiation. Classically, electromagnetic radiation can be pictured as waves flowing through space at the speed of light. The waves are not waves of anything substantive, but are in fact ripples in a state of a field. These waves do carry energy, and each wave has a specific direction, frequency and polarization state. This is called a "propagating mode of the electromagnetic field." &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;Each mode is subject to the Heisenberg uncertainty principle. To understand the meaning of this, the theory of electromagnetic radiation is quantized by treating each mode as an equivalent harmonic oscillator. From this analogy, every mode of the field must have hf/2 as its average minimum energy. That is a tiny amount of energy, but the number of modes is enormous, and indeed increases as the square of the frequency. The product of the tiny energy per mode times the huge spatial density of modes yields a very high theoretical energy density per cubic centimeter. &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;From this line of reasoning, quantum physics predicts that all of space must be filled with electromagnetic zero-point fluctuations (also called the zero-point field) creating a universal sea of zero-point energy. The density of this energy depends critically on where in frequency the zero-point fluctuations cease. Since space itself is thought to break up into a kind of quantum foam at a tiny distance scale called the Planck scale (10&lt;SUP&gt;-33&lt;/SUP&gt; cm), it is argued that the zero point fluctuations must cease at a corresponding Planck frequency (10&lt;SUP&gt;43&lt;/SUP&gt; Hz). If that is the case, the zero-point energy density would be 110 orders of magnitude greater than the radiant energy at the center of the Sun. &lt;FONT face=verdana color=maroon size=2 ,&gt;
&lt;P align=justify&gt;CONNECTION TO INERTIA AND GRAVITATION &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;When a passenger in an airplane feels pushed against his seat as the airplane accelerates down the runway, or when a driver feels pushed to the left when her car makes a sharp turn to the right, what is doing the pushing? Since the time of Newton, this has been attributed to an innate property of matter called inertia. In 1994 a process was discovered whereby the zero-point fluctuations could be the source of the push one feels when changing speed or direction, both being forms of acceleration. The zero-point fluctuations could be the underlying cause of inertia. If that is the case, then we are actually sensing the zero-point energy with every move we make (see &lt;A href="http://www.calphysics.org/inertia.html" target="_new"&gt;origin of inertia&lt;/A&gt;). &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;The principle of equivalence would require an analogous connection for gravitation. Einstein's general relativity successfully accounts for the motions of freely-falling objects on geodesics (the "shortest" distance between two points in curved spacetime), but does not provide a mechanism for generating a gravitational force for objects when they are forced to deviate from geodesic tracks. It has been found that an object undergoing acceleration or one held fixed in a gravitational field would experience the same kind of asymmetric pattern in the zero-point field giving rise to such a reaction force. The weight you measure on a scale would therefore be due to zero-point energy (see &lt;A href="http://www.calphysics.org/gravitation.html" target="_new"&gt;gravitation&lt;/A&gt;). &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;The possibility that electromagnetic zero-point energy may be involved in the production of inertial and gravitational forces opens the possibility that both inertia and gravitation might someday be controlled and manipulated. This could have a profound impact on propulsion and space travel. &lt;IMG height=22 src="http://www.xanga.com/Images/clueless.gif" width=15&gt;&lt;/P&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;</description><comments>http://www.xanga.com/BiG_SCaR_BRuCe/47333005/item.html#firstcomment</comments></item><item><title>Wednesday, December 03, 2003</title><link>http://www.xanga.com/BiG_SCaR_BRuCe/47332836/item.html</link><guid>http://www.xanga.com/BiG_SCaR_BRuCe/47332836/item.html</guid><pubDate>Wed, 03 Dec 2003 12:52:15 GMT</pubDate><description>&lt;P align=justify&gt;Quantum physics predicts the existence of an underlying sea of zero-point energy at every point in the universe.

Since the time of Newton, this has been attributed to an innate property of matter called inertia. In 1994 a process was discovered whereby the zero-point fluctuations could be the source of the push one feels when changing speed or direction, both being forms of acceleration. The zero-point fluctuations could be the underlying cause of inertia. If that is the case, then we are actually sensing the zero-point energy with every move we make (see &lt;A href="http://www.calphysics.org/inertia.html" target="_new"&gt;origin of inertia&lt;/A&gt;). &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;The principle of equivalence would require an analogous connection for gravitation. Einstein's general relativity successfully accounts for the motions of freely-falling objects on geodesics (the "shortest" distance between two points in curved spacetime), but does not provide a mechanism for generating a gravitational force for objects when they are forced to deviate from geodesic tracks. It has been found that an object undergoing acceleration or one held fixed in a gravitational field would experience the same kind of asymmetric pattern in the zero-point field giving rise to such a reaction force. The weight you measure on a scale would therefore be due to zero-point energy (see &lt;A href="http://www.calphysics.org/gravitation.html" target="_new"&gt;gravitation&lt;/A&gt;). &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;The possibility that electromagnetic zero-point energy may be involved in the production of inertial and gravitational forces opens the possibility that both inertia and gravitation might someday be controlled and manipulated. This could have a profound impact on propulsion and space travel. &lt;IMG height=15 src="http://www.xanga.com/Images/silly.gif" width=15&gt;&lt;/P&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;&lt;/FONT&gt;</description><comments>http://www.xanga.com/BiG_SCaR_BRuCe/47332836/item.html#firstcomment</comments></item><item><title>Wednesday, December 03, 2003</title><link>http://www.xanga.com/BiG_SCaR_BRuCe/47332818/item.html</link><guid>http://www.xanga.com/BiG_SCaR_BRuCe/47332818/item.html</guid><pubDate>Wed, 03 Dec 2003 12:52:02 GMT</pubDate><description>&lt;P align=justify&gt;Quantum physics predicts the existence of an underlying sea of zero-point energy at every point in the universe. This is different from the cosmic microwave background and is also referred to as the electromagnetic quantum vacuum since it is the lowest state of otherwise empty space. This energy is so enormous that most physicists believe that even though zero-point energy seems to be an inescapable consequence of elementary quantum theory, it cannot be physically real, and so is subtracted away in calculations. &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;A minority of physicists accept it as real energy which we cannot directly sense since it is the same everywhere, even inside our bodies and measuring devices. From this perspective, the ordinary world of matter and energy is like a foam atop the quantum vacuum sea. It does not matter to a ship how deep the ocean is below it. If the zero-point energy is real, there is the possibility that it can be tapped as a source of power or be harnassed to generate a propulsive force for space travel. &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;The propellor or the jet engine of an aircraft push air backwards to propel the aircraft forward. A ship or boat propellor does the same thing with water. On Earth there is always air or water available to push against. But a rocket in space has nothing to push against, and so it needs to carry propellant to eject in place of air or water. The fundamental problem is that a deep space rocket would have to start out with all the propellant it will ever need. This quickly results in the need to carry more and more propellant just to propel the propellant. The breakthrough one wishes for deep space travel is to overcome the need to carry propellant at all. How can one generate a propulsive force without carrying and ejecting propellant? &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;There is a force associated with the electromagnetic quantum vacuum: the Casimir force. This force is an attraction between parallel metallic plates that has now been well measured and can be attributed to a minutely tiny imbalance in the zero-point energy in the cavity between versus the region outside the plates. This is not useful for propulsion since it symmetrically pulls on the plates. However if some asymmetric variation of the Casimir force could be identified one could in effect sail through space as if propelled by a kind of quantum fluctuation wind. This is pure speculation. &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;The other requirement for space travel is energy. A thought experiment published by physicist Robert Forward in 1984 demonstrated how the Casimir force could in principle be used to extract energy from the quantum vacuum (&lt;A href="http://www.calphysics.org/articles/Forward1984.pdf" target="_new"&gt;Phys. Rev. B, 30, 1700, 1984&lt;/A&gt;). Theoretical studies in the early 1990s (&lt;A href="http://www.calphysics.org/articles/CP93.pdf" target="_new"&gt;Phys. Rev. E, 48, 1562, 1993&lt;/A&gt;) verified that this was not contradictory to the laws of thermodynamics (since the zero-point energy is different from a thermal reservoir of heat). Unfortunately the Forward process cannot be cycled to yield a continuous extraction of energy. A Casimir engine would be one whose cylinders could only fire once, after which the engine become useless. &lt;FONT face=verdana color=maroon size=2 ,&gt;
&lt;P align=justify&gt;ORIGIN OF ZERO-POINT ENERGY &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;The basis of zero-point energy is the Heisenberg uncertainty principle, one of the fundamental laws of quantum physics. According to this principle, the more precisely one measures the position of a moving particle, such as an electron, the less exact the best possible measurement of momentum (mass times velocity) will be, and vice versa. The least possible uncertainty of position times momentum is specified by Planck's constant, h. A parallel uncertainty exists between measurements involving time and energy. This minimum uncertainty is not due to any correctable flaws in measurement, but rather reflects an intrinsic quantum fuzziness in the very nature of energy and matter. &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;A useful calculational tool in physics is the ideal harmonic oscillator: a hypothetical mass on a perfect spring moving back and forth. The Heisenberg uncertainty principle dictates that such an ideal harmonic oscillator -- one small enough to be subject to quantum laws -- can never come entirely to rest, since that would be a state of exactly zero energy, which is forbidden. In this case the average minimum energy is one-half h times the frequency, hf/2. &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;Radio waves, light, X-rays, and gamma rays are all forms of electromagnetic radiation. Classically, electromagnetic radiation can be pictured as waves flowing through space at the speed of light. The waves are not waves of anything substantive, but are in fact ripples in a state of a field. These waves do carry energy, and each wave has a specific direction, frequency and polarization state. This is called a "propagating mode of the electromagnetic field." &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;Each mode is subject to the Heisenberg uncertainty principle. To understand the meaning of this, the theory of electromagnetic radiation is quantized by treating each mode as an equivalent harmonic oscillator. From this analogy, every mode of the field must have hf/2 as its average minimum energy. That is a tiny amount of energy, but the number of modes is enormous, and indeed increases as the square of the frequency. The product of the tiny energy per mode times the huge spatial density of modes yields a very high theoretical energy density per cubic centimeter. &lt;FONT face=verdana color=black size=2 ,&gt;
&lt;P align=justify&gt;From this line of reasoning, quantum physics predicts that all of space must be filled with electromagnetic zero-point fluctuations (also called the zero-point field) creating a universal sea of zero-point energy. The density of this energy depends critically on where in frequency the zero-point fluctuations cease. Since space itself is thought to break up into a kind of quantum foam at a tiny distance scale called the Planck scale (10&lt;SUP&gt;-33&lt;/SUP&gt; cm), it is argued that the zero point fluctuations must cease at a corresponding Planck frequency (10&lt;SUP&gt;43&lt;/SUP&gt; Hz). If that is the case, the zero-point energy density would be 110 orders of magnitude greater than the radiant energy at the center of the Sun. &lt;FONT face=verdana color=maroon size=2 ,&gt;
