Einsteins Theory of Relativity

Einsteins Theory of Relativity Einsteins theory of relativity is a famous theory, but its little understood. The theory of relativity refers to two different elements of the same theory: general relativity and special relativity. The theory of special relativity was introduced first  and was later considered to be a special case of the more comprehensive theory of general relativity. General relativity is a  theory of gravitation  that   Albert Einstein developed by  between 1907 and 1915, with contributions from many others after 1915. Theory of Relativity Concepts Einsteins theory of relativity includes the interworking of several different concepts, which include: Einsteins Theory of Special Relativity - localized behavior of objects in inertial frames of reference, generally only relevant at speeds very near the speed of lightLorentz Transformations - the transformation equations used to calculate the coordinate changes under special relativityEinsteins Theory of General Relativity - the more comprehensive theory, which treats gravity as a geometric phenomenon of a curved spacetime coordinate system, which also includes noninertial (i.e. accelerating) frames of referenceFundamental Principles of Relativity What Is Relativity? Classical relativity (defined initially by Galileo Galilei and refined by Sir Isaac Newton) involves a simple transformation between a moving object and an observer in another inertial frame of reference. If you are walking in a moving train, and someone stationary on the ground is watching, your speed relative to the observer will be the sum of your speed relative to the train and the trains speed relative to the observer. Youre in one inertial frame of reference, the train itself (and anyone sitting still on it) are in another, and the observer is in still another. The problem with this is that light was believed, in the majority of the 1800s, to propagate as a wave through a universal substance known as the ether, which would have counted as a separate frame of reference (similar to the train in the above example). The famed Michelson-Morley experiment, however, had failed to detect Earths motion relative to the ether and no one could explain why. Something was wrong with the classical interpretation of relativity as it applied to light ... and so the field was ripe for a new interpretation when Einstein came along. Introduction  to  Special Relativity In 1905,  Albert Einstein  published (among other things) a paper called  On the Electrodynamics of Moving Bodies  in the journal  Annalen der Physik. The paper presented the theory of  special relativity, based  on  two postulates: Einsteins PostulatesPrinciple of Relativity (First Postulate):   The laws of physics are the same for all inertial reference frames.Principle of Constancy of the Speed of Light (Second Postulate):  Light always propagates through a vacuum (i.e. empty space or free space) at a definite  velocity, c, which is independent of the state of motion of the emitting body. Actually, the paper presents a more formal, mathematical formulation of the postulates. The phrasing of the postulates  are  slightly different from textbook to  textbook  because of translation issues, from mathematical German to comprehensible English. The second postulate is often mistakenly written to include that the speed of light in a vacuum is  c  in all frames of reference. This is actually a derived result of the two postulates, rather than part of the second postulate itself. The first postulate is pretty much common sense. The second postulate, however, was the revolution. Einstein had already introduced the  photon theory of light  in his paper on the  photoelectric effect  (which rendered the ether  unnecessary). The second postulate, therefore, was a consequence of massless photons moving at the velocity  c  in a vacuum. The ether no longer had a special role as an absolute inertial frame of reference, so it was not only unnecessary but qualitatively useless under special relativity. As for the paper itself, the goal was to reconcile Maxwells equations for electricity and magnetism with the motion of electrons near the speed of light. The result of Einsteins paper was to introduce new coordinate transformations, called  Lorentz transformations, between inertial frames of reference. At slow speeds, these transformations were essentially identical to the classical model, but at high speeds, near the speed of light, they produced radically different results. Effects of Special Relativity Special relativity yields several consequences from applying Lorentz transformations at high velocities (near the speed of light). Among them are: Time dilation (including the popular twin paradox)Length contractionVelocity transformationRelativistic velocity additionRelativistic doppler effectSimultaneity clock synchronizationRelativistic momentumRelativistic kinetic energyRelativistic massRelativistic total energy In addition, simple algebraic manipulations of the above concepts yield two significant results that deserve individual mention. Mass-Energy Relationship Einstein was able to show that mass and energy were related, through the famous formula  Emc2. This relationship was proven most dramatically to the world when nuclear bombs released the energy of mass in Hiroshima and Nagasaki at the end of World War II. Speed of Light No object with mass can accelerate to precisely the speed of light. A massless object, like a photon, can move at the speed of light. (A photon doesnt actually accelerate, though, since it  always  moves exactly at  the speed of light.) But for a physical object, the speed of light is a limit. The  kinetic energy  at the speed of light goes to infinity, so it can never be reached by acceleration. Some have pointed out that an object could in theory move at greater than the speed of light, so long as it did not accelerate to reach that speed. So far no physical entities have ever displayed that property, however. Adopting Special Relativity In 1908,  Max Planck  applied the term theory of relativity to describe these concepts, because of the key role relativity played in them. At the time, of course, the term applied only to special relativity, because there was not yet any general relativity. Einsteins relativity was not immediately embraced by physicists as a  whole  because it seemed so theoretical and counterintuitive. When he received his 1921 Nobel Prize, it was specifically for his solution to the  photoelectric effect  and for his contributions to Theoretical Physics. Relativity was still too controversial to be specifically referenced. Over time, however, the predictions of special relativity have been shown to be true. For example, clocks flown around the world have been shown to slow down by the duration predicted by the theory. Origins of Lorentz Transformations Albert Einstein  didnt create the coordinate transformations needed for special relativity. He didnt have  to because the Lorentz transformations that he needed already existed. Einstein was a master at taking previous work and adapting it to new situations, and he did so with the Lorentz transformations just as he had used Plancks 1900 solution to the  ultraviolet catastrophe  in  black body radiation  to craft his solution to the  photoelectric effect, and thus develop the  photon theory of light. The transformations were actually first published by Joseph Larmor in 1897. A slightly different version had been published a decade earlier by Woldemar Voigt, but his version had a square in the time dilation equation. Still, both versions of the equation were shown to be invariant under Maxwells equation. The mathematician and physicist Hendrik Antoon Lorentz proposed the idea of a local time to explain relative simultaneity in 1895, though, and began working independently on similar transformations to explain the null result  in  the Michelson-Morley experiment. He published his coordinate transformations in 1899, apparently still unaware of Larmors publication, and added time dilation in 1904. In 1905, Henri Poincare modified the algebraic formulations and attributed them to Lorentz with the name Lorentz transformations, thus changing Larmors chance at immortality in this regard. Poincares formulation of the transformation was, essentially, identical to that which Einstein would use. The transformations apply to a four-dimensional coordinate system, with three spatial coordinates (x,  y,   z) and  one-time  coordinate (t). The new coordinates are denoted with an apostrophe, pronounced prime, such that  x is pronounced  x-prime. In the example below, the velocity is in the  xx direction, with velocity  u: x (   x  -   ut  ) / sqrt ( 1 -   u2  /   c2  )y   yz   zt {  t  - (  u  /  c2  )  x  } / sqrt ( 1 -  u2  /  c2  ) The transformations are provided primarily for demonstration purposes. Specific applications of them will be dealt with separately. The term 1/sqrt (1 -  u2/c2) so frequently appears in relativity that it is denoted with the Greek symbol  gamma  in some representations. It should be noted that in the cases when  u  Ã‚  c, the denominator collapses to essentially the sqrt(1), which is just 1.  Gamma  just becomes 1 in these cases. Similarly,  the  u/c2  term also becomes very small. Therefore, both dilation of space and time are non-existent to any significant level at speeds much slower than the speed of light in a vacuum. Consequences of the Transformations Special relativity yields several consequences from applying Lorentz transformations at high velocities (near the speed of light). Among them are: Time dilation  (including the popular Twin Paradox)Length contractionVelocity transformationRelativistic velocity additionRelativistic doppler effectSimultaneity clock synchronizationRelativistic momentumRelativistic kinetic energyRelativistic massRelativistic total energy Lorentz Einstein Controversy Some people point out that most of the actual work for the special relativity had already been done by the time Einstein presented it. The concepts of dilation and simultaneity for moving bodies were already in place and the mathematics had already been developed by Lorentz Poincare. Some go so far as to call Einstein a plagiarist. There is some validity to these charges. Certainly, the revolution of Einstein was built on the shoulders of a lot of other work, and Einstein got far more credit for his role than those who did the grunt work. At the same time, it must be considered that Einstein took these basic concepts and mounted them on a theoretical framework which made them not merely mathematical tricks to save a dying theory (i.e. the ether), but rather fundamental aspects of nature in their own right. It is unclear that Larmor, Lorentz, or Poincare intended so bold a move, and history has rewarded Einstein for this insight boldness. Evolution of General Relativity In  Albert Einsteins  1905 theory (special relativity), he showed that among inertial frames of reference there was no preferred frame. The development of general relativity came about, in part, as an attempt to show that this was true among non-inertial (i.e. accelerating) frames of reference as well. In 1907, Einstein published his first article on gravitational effects on  light  under special relativity. In this paper, Einstein outlined his equivalence principle, which stated that observing an experiment on the Earth (with gravitational acceleration  g) would be identical to observing an experiment in a rocket ship that moved at a speed of  g. The equivalence principle can be formulated as: we [...] assume the complete physical equivalence of a gravitational field and a corresponding acceleration of the reference system.as Einstein said or, alternately, as one  Modern Physics  book presents it:There is no local experiment that can be done to distinguish between the effects of a uniform gravitational field in a nonaccelerating inertial frame and the effects of a uniformly accelerating (noninertial) reference frame. A second article on the subject appeared in 1911, and by 1912 Einstein was actively working to conceive of a general  theory of relativity  that would explain special relativity, but would also explain gravitation as a geometric phenomenon. In 1915, Einstein published a set of differential equations known as the  Einstein field equations. Einsteins  general relativity  depicted the universe as a geometric system of three spatial and one time dimensions. The presence of mass, energy, and momentum (collectively quantified as  mass-energy density  or  stress-energy) resulted in a bending of this space-time coordinate system. Gravity, therefore, was movement along the simplest or least-energetic route along this curved space-time. The Math of General Relativity In the simplest possible terms, and stripping away the complex mathematics, Einstein found the following relationship between the curvature of space-time and mass-energy density: (curvature of space-time) (mass-energy density) * 8   pi G  /   c4 The equation shows a direct, constant proportion. The gravitational constant,  G, comes from  Newtons law of gravity, while the dependence upon the speed of light,  c, is expected from the theory of special relativity. In a case of zero (or near zero) mass-energy density (i.e. empty space), space-time is flat. Classical gravitation is a special case of gravitys manifestation in a relatively weak  gravitational field, where the  c4  term (a very big denominator) and  G  (a very small numerator) make the curvature correction small. Again, Einstein didnt pull this out of a hat. He worked heavily with Riemannian geometry (a non-Euclidean geometry developed by mathematician Bernhard Riemann years earlier), though the resulting space was a 4-dimensional Lorentzian manifold rather than a strictly Riemannian geometry. Still, Riemanns work was essential for Einsteins own field equations to be complete. What Does General Relativity Mean? For an analogy to general relativity, consider that you stretched out a  bed sheet  or piece of elastic flat, attaching the corners firmly to some secured posts. Now you begin placing things of various weights on the sheet. Where you place something very light, the sheet will curve downward under the weight of it a little bit. If you put something heavy, however, the curvature would be even greater. Assume theres a heavy object sitting on the sheet and you place a second, lighter, object on the sheet. The curvature created by the heavier object will cause the lighter object to slip along the curve toward it, trying to reach a point of equilibrium where it no longer moves. (In this case, of course, there are other considerations a ball will roll further than a cube would slide, due to frictional effects and such.) This is similar to how general relativity explains gravity. The curvature of a light object doesnt affect the heavy object much, but the curvature created by the heavy object is what keeps us from floating off into space. The curvature created by the Earth keeps the moon in orbit, but at the same  time, the curvature created by the moon is enough to affect the tides. Proving General Relativity All of the findings of special relativity also support general relativity, since the theories are consistent. General relativity also explains all of the phenomena of classical mechanics, as they too are consistent. In addition, several findings support the unique predictions of general relativity: Precession of perihelion of MercuryGravitational deflection of starlightUniversal expansion (in the form of a  cosmological constant)Delay of radar echoesHawking radiation from black holes Fundamental Principles of Relativity General Principle of Relativity:  The laws of physics must be identical for all observers, regardless of whether or not they are accelerated.Principle of General Covariance:  The laws of physics must take the same form in all coordinate systems.Inertial Motion is Geodesic Motion:  The world lines of particles unaffected by forces (i.e. inertial motion) are timelike or null geodesic of spacetime. (This means the tangent vector is either negative or zero.)Local Lorentz Invariance:  The rules of special relativity apply locally for all inertial observers.Spacetime Curvature:  As described by Einsteins field equations, the curvature of spacetime in response to mass, energy, and momentum results in gravitational influences being viewed as a form of inertial motion. The equivalence principle, which  Albert Einstein  used as a starting point for general relativity, proves to be a consequence of these principles. General Relativity the Cosmological Constant In 1922, scientists discovered that application of Einsteins field equations to cosmology resulted in an expansion of the universe. Einstein, believing in a static universe (and therefore thinking his equations were in error), added a  cosmological constant  to the field equations, which allowed for static solutions. Edwin Hubble, in 1929, discovered that there was redshift from distant stars, which implied they were moving with respect to the Earth. The universe, it seemed, was expanding. Einstein removed the cosmological constant from his equations, calling it the biggest blunder of his career. In the 1990s, interest in the cosmological constant returned in the form of  dark energy. Solutions to  quantum field theories  have resulted in a huge amount of energy in the quantum vacuum of space, resulting in an accelerated expansion of the universe. General Relativity and Quantum Mechanics When physicists attempt to apply quantum field theory to the  gravitational field, things get very messy. In mathematical terms, the physical quantities involve diverge, or result in infinity. Gravitational fields under general relativity require an infinite number of correction, or renormalization, constants to adapt them into solvable equations. Attempts to solve this renormalization problem lie at the heart of the theories of  quantum gravity. Quantum gravity theories typically work backward, predicting a theory and then testing it rather than actually attempting to determine the infinite constants needed. Its an old trick in physics, but so far none of the theories have been adequately proven. Assorted Other Controversies The major problem with general relativity, which has been otherwise highly successful, is its overall incompatibility with quantum mechanics. A large chunk of theoretical physics is devoted toward trying to reconcile the two concepts: one which predicts macroscopic phenomena across space and one which predicts microscopic phenomena, often within spaces smaller than an atom. In addition, there is some concern with Einsteins very notion of spacetime. What is spacetime? Does it physically exist? Some have predicted a quantum foam that spreads throughout the universe. Recent attempts at  string theory  (and its subsidiaries) use this or other quantum depictions of spacetime. A recent article in New Scientist magazine predicts that spactime may be a quantum  superfluid  and that the entire universe may rotate on an axis. Some people have pointed out that if spacetime exists as a physical substance, it would act as a universal frame of reference, just as the ether had. Anti-relativists are thrilled at this prospect, while others see it as an unscientific attempt to discredit Einstein by resurrecting a century-dead concept. Certain issues with black hole singularities, where the spacetime curvature approaches infinity, have also cast doubts on whether general relativity accurately depicts the universe. It is hard to know for sure, however, since  black holes  can only be studied from afar at present. As it stands now, general relativity is so successful that its hard to imagine it will be harmed much by these inconsistencies and controversies until a phenomena comes up which actually contradicts the very predictions of the theory. Quotes About RelativitySpacetime grips mass, telling it how to move, and mass grips spacetime, telling it how to curve - John Archibald Wheeler.The theory appeared to me then, and still does, the greatest feat of human thinking about nature, the most amazing combination of philosophical penetration, physical intuition, and mathematical skill. But its connections with experience were slender. It appealed to me like a great work of art, to be enjoyed and admired from a distance. - Max Born

Analysing The Concept Of Karma

Analysing The Concept Of Karma The Hindu and Buddhist religions both believe in karma. In the Hindu religion karma influences how you are born in your next life. You can be born in lower life forms such as an animal, plant, or insect. You could even be born into a lower caste system. It works the opposite way as well and can cause you to be reborn in a higher form even as a demigod or superhuman. Buddhists have a different take on karma. The Buddha rejected the notion of a soul but accepted some notion of rebirth. Buddha says that even though there is no soul the personalities of a being could recombine and continue from one life time to another. He uses the example of a flame going from one candle to another or the wind on blades of grass. To understand karma first it needs to be defined. Karma can be described as a form of cause and effect. The dictionary defines karma as sum of person’s actions in one of his successive states of existence, viewed as deciding his fate for the next. In Sanskrit karma is d efined as volitional action that is undertaken deliberately or knowingly. This also fits together as self-determination and a strong will power to abstain from inactivity. Karma also separates human beings from other creatures in the world. Karma is a notion that constantly proves the Newton theory of every action creates an equal and opposite reaction. Every time we do something we create a cause and in time will produce its corresponding reaction. It is the personality of the human that causes either negative or positive karma. Karma could be caused by both the physical and mental aspects of the body regardless of if it brings achievement now or in the future. Karma cannot be affected by the natural reflexes of the body. â€Å"A person is responsible for his or her own karma†(Karma and Reincarnation, 2010). In other words it is up to a person to give themselves good karma and move to a higher form in the next life or their doing for bad karma and devolving to a lower form. There are three types of karma savtik karma, rajasik karma, tamasik karma. Savtik karma is without attachment, selfless and for the benefit of others. Rajasik karma is selfish where ones focus is on ones gains to oneself. Tamasik karma is undertaken without regard to consequences and is supremely selfish and savage. The ancient yogis have assigned three categories to karma. These are sanchita, prarabdha, and kriyamana. The first category, sanchita, is the sum total of past karma yet to be resolved. Prarabdha, the second category, is the portion of sanchita being experienced in the present life. The third category, kriyamana, is the karma you are currently creating. It is important to understand that past negative karma can be altered into a smoother, easier state through the loving, heart-chakra nature, through dharma and sadhana. If you live religiously well you will create positive karma for the future and soften negative karma of the past.

An Introduction to the Cold War Assignment Example | Topics and Well Written Essays - 1000 words

An Introduction to the Cold War - Assignment Example Countries in Western Europe also had some really dangerous weapons, these weapons included long-range missiles, bombs, guns so on and so forth. The countries did not want to take any risk as they were all recovering from the damage caused by the Second World War and another war at that time would have literary wiped them off the map. To conclude it is very fair to say that the countries were afraid of each other because they had some really dangerous weapons which were already used in the Second World War, United States, for instance, had Atom Bombs which caused damage beyond repair in Japan. The world got divided into several different parts after the World Wars; these World Wars caused damage beyond repair. Cold war began after the end of the Second World War, the Second World War ended in the year 1945, The US and the Soviet Union were the ones directly involved in the cold war. The cold war was a situation in which countries did not fight directly; instead, they choose to fight indirectly with each other. â€Å"Do note that USSR in 1945 was Russia post-1917 and included all the various countries that now exist individually (Ukraine, Georgia etc) but after the war, they were part of this huge country up until the collapse of the Soviet Union (the other name for the USSR).† (What was the Cold War?) The US and the Soviet Union were the strongest countries once the Second World War ended and both wanted to dominate each other. To match each other stride for stride they started fighting indirectly. This indirect war had several repercussions upon the other countries and it also affected the US and the Soviet Union. Weapons weren’t used in this cold war, words were used as weapons and the main enemies involved in this war consistently tried to make each other look foolish. The leaders involved in the cold war consistently kept changing but the war still continued, this goes to show the desire to dominate each other and most of the wars occur because of this domination of one country over another.  Ã‚  

My Philosophy of Education :: Teaching Teachers Essays

My Philosophy of Education As a military wife, I have had the experience of working in several different school systems. I was a substitute teacher and a teaching assistant for four years. I started my college education right after high school. However, I halted my studies when my ex-husband and I were stationed in Germany. Soon after, my children came and consumed most of my time. If I was asked the question now about my career choice at 18, I would have to say that I am glad I got to experience the world first. I have enjoyed raising my children and working in the school system. I am now back in college after a 16-year break. I am more prepared mentally and I am focused and determined to reach my goals of becoming a teacher. I know that being a teacher is my true calling in life. Over the years, I have had the privilege of working with ten different teachers. I have considered their examples to be exceptional reference material. I see things that have worked and things I can relate to. I have also seen things that didn’t work. I have been very fortunate to be able to give my profession of choice a trial run before spending this time getting prepared for a career in teaching. An eclectic approach to teaching and learning is what I would like to have in my classroom. I would draw my practices from progressivism, essentialism, existentialism and realism. I also understand that some things will work with one class but may not work well with another. I know that I will need to be flexible when working with a diverse number of individuals. With progressivism, I believe that there should be instruction where students participate in critical thinking, problem solving and decision-making. These exercises help children to survive in the real world. I think cooperative learning will teach children to work well with others but also draw off each other’s ideas. Applying essentialism in the classroom is where the basic core curriculum will come in. There will be standards that need to be met in these areas. This will be where creativity needs to be implemented to get the material that is required across to the children. I believe in time-on-task emphasis as well as modeling appropriate behavior.

Is it Morally wrong for those under the age of 18 to play GTA V? Essay

Some people, mainly young over the age of eighteen , would say that people under the age of 18 shouldn’t play Grand Theft Auto five for many reasons. The main one is that they spend more time on there consoles playing those games then studying and working hard to complete homework tasks effectively. Some might suggest one of the those reasons would be that it is certified 18 and they would be breaking the law in playing that game. Another thing you could say is that GTA has sexual references and strong language and younger people shouldn’t be exposed to that rude behaviour. Some people already think the youth of today are over exposed to things they shouldn’t be exposed to like foul language and those types of sexual references. Another point that could be raised about this video game is it’s racial discrimination and it’s sexist views on the world. Girls especially would find that this game is offensive towards them in the way women are treated in this game regardless of it’s location or year it’s set in. Some people from different cultures my find this game offensive because of how different races are portrayed or how they are treated. Teachers would prefer children especially those in GCSE years to focus on their work instead of playing a silly video game which isn’t important in the long run but their grades are. Other people, mainly those under the age of 18, would argue this point. They would say it is okay to play GTA five because their family members or people around them play it. People in high school would say things like â€Å"We swear anyway.† or things like â€Å"It’s just a video game.† They like their parents or who ever let them play it in the first place would believe that it’s not like they’d re-enact these things that happen in the game in real life. Those playing the game would say that they don’t see the problem with the racist, sexist and discriminative views of this game. They might find those things give the game it’d character or make the game more interesting. They could also argue that even though it’s certified 18 it didn’t stop them playing the last Grand Theft Auto game or any other 18 rated game like some of the Call Of Duty games or even games like Borderlands two and that those games were never questioned about even if lots of people knew they were playing them I think that people under the age of 18 shouldn’t play GTA V because I believe that they should focus more on their studies especially towards the end of their teen age years where their school focus is more important on their exams than on a video game. I see that from a teacher point of view they would agree with that. From a girls point of view I believe that this game shouldn’t be played by under 18’s because it shows girls off in a bad light and is offensive to women. This game also shows ignorance towards different races and the difference between men and women. The discrimination between races and women shows that the people who create this game obviously didn’t intend for a younger audience.

Love Metaphors From Literature and Pop Culture

In literature, music, and popular culture, love is often used as a metaphor, a  trope  or  figure of speech  in which an implied comparison is made between two unlike things that actually have something in common. For example, when Neil Young sings, Love is a rose, the word rose is the vehicle for the term love, the tenor. Or as Milan Kundera wrote in The Unbearable Lightness of Being, I have said before that metaphors are dangerous. Love begins with a metaphor. He might have added that love sometimes ends with a metaphor as well. Like the experience of love itself, metaphors make connections. So its no surprise that love has been imagined, examined, and remembered through a wide variety of figurative comparisons, as the quotes below show. Love as a Fruit or Plant As the collection of passages in this and the below sections demonstrate, love has been compared to everything from a plant to a truck. The metaphors in this collection are anything but conventional. Love is a fruit, in season at all times and within the reach of every hand. Anyone may gather it and no limit is set.– Mother Teresa, No Greater Love I look at you and wham, Im head over heels.I guess that love is a banana peel.I feel so bad and yet Im feeling so well.I slipped, I stumbled, I fell– Ben Weisman and Fred Wise, I Slipped, I Stumbled, I Fell, sung by Elvis Presley in the film Wild in the Country Love is a spice with many tastes—a dizzying array of textures and moments.– Wayne Knight as Newman in the final episode of Seinfeld Now that youre gone I can seeThat love is a garden if you let it go.It fades away before you know,And love is a garden—it needs help to grow.– Jewel and Shaye Smith, Love Is a Garden Love is a plant of the most tender kind,That shrinks and shakes with every ruffling wind– George Granville, The British Enchanters As a Phenomenon of Nature Washington Irving  compared love to the rosy cloud in the morning of life, but many others have likened love to various phenomena of nature from lightning to stars and fire, as the quotes in this section demonstrate. Oh, love is a journey with water and stars,with drowning air and storms of flour;love is a clash of lightnings,two bodies subdued by one honey.– Pablo Neruda, Sonnet 12 [Love] is an ever-fixed markThat looks on tempests and is never shaken;It is the star to every wandering bark,Whose worths unknown, although his height be taken.– William Shakespeare, Sonnet 116 Love is a fire.It burns everyone.It disfigures everyone.It is the worlds excusefor being ugly.– Leonard Cohen, The Energy of Slaves Loves fire, if it once goes out, is hard to kindle.– German proverb An Animal Kurt Vonnegut called love a hawk with velvet claws, but many singers, writers, authors, and figures in popular culture have compared love to various animals, including dogs, birds, and even a crocodile. Love is a dog from hell.– Charles Bukowski, Love Is a Dog From Hell Loves wing  moults  when caged and captured,Only free he soars enraptured.– Thomas Campbell, Loves Philosophy Love is a crocodile in the river of desire.– Bhartá ¹â€ºhari, Ã…Å¡atakatraya Happiness is the china shop; love is the bull.–  H.L. Mencken, A Little Book in C Major And Even a Disease Love has been compared to many things, but surprisingly, some have likened it to a disease, as the eclectic mix of quotes shows in this final section.
