purpose of the book seems to be to persuade readers of what the team devoutly believes Newtonian reduction. 1 Even a simple spherical pendulum can exhibit chaos When the top end of the string is oscillated the ball swings about For some freuencies the ball settles into a regular orbital motion For other oscillation freuencies the ball s motion is so erratic that it is essentially random and unpredictable2 Suppose you re drawing a line from a pointlet s call P on a parallel line to a pointlet s call on the other parallel line If you choose wrongly your first pointP to draw the line then your final point will be wrong too However error in location of first point and second point is eualP P This example demonstrates a nonchaotic system If we are a little ignorance about initial state our ignorance about final state will be a little too Now suppose there is a point on a circle You re trying to dedicate if we roll the circle on a parallel line which location on the parallel line the point will touch If you choose wrongly your first point then your final point will be wrong too Contrary to first example error in the location will be much greater then error of the point on circle P P This example demonstrates a chaotic system Our slight ignorance about the initial state now leads to a great uncertainty of the final state3 The sensitivity is not just a result of human inability to calculate with enough precision The mathematical concept of a line is a kind of fiction To label every point on a line you need also irrational numbers which you cannot show it as one whole number divided by another whole number beside rational ones Even one irrational number involves an infinite uantity of information For example we can try to calculate the motion of a pendulum by using one billion decimals of pi Nonetheless the number we use won t be pi but a rational number that is approximation of pi The slight difference we ignore will lead an uncertainty as time progress Therefore Chaos evidently provides us with a bridge between the laws of physics and the laws of randomness4 Why is it possible to know something such as the law of falling objects without knowing everything Indeed why is it possible to know so much without knowing everything Part of the reason for the success of the step by step approach is that many physical systems are approximately linear in nature Imagine a sponge soaking up water The weight of the sponge will at first increase proportionally with the number of water drops like a linear system However after a while the sponge gets very wet it will start to saturate like a nonlinear system The success of linear methods over the past three centuries has however tended to obscure the fact that real systems almost always turn out to become nonlinear When nonlinearity becomes important it is no longer possible to analyse because the whole is now greater then the sum of its parts Besides a nonlinear system must be understood in its totalityconstraints boundary conditions and initial conditions5 If a stone is dropped in a pond the ripples that are created spread out from the point of impact and gradually die away This kind of waves consists of a train of undulations A wave group like this is actually made up of a lot of waves of different amplitude and wavelengths superimposed on one another Near the center of the group all these contributing waves are or less in phase and so they reinforce each other to make a large disturbance Near the edges the waves get out of phase because of their different wavelengths and they tend to cancel each other and reduce the disturbance The particular shape of the wave group depends on the specific mixture of waves present As the wave group progress however its state changes because long waves on water travel faster than short waves The phenomenon is called dispersion because it causes the wave group to fade away For a single hump of water to propagate in such a dispersive medium without spreading out and fading away reuires another factor to counteract the effects of dispersion This new factor is an example of nonlinearity at work The sort of waves we usually witness are called linear waves Any two linear waves when superimposed produce a merged wave this to apply it is necessary that the speed of each wave although depending on its length does not depend upon its height The assumption of linearity is valid for water waves only if their amplitude is small compared with the depth of water If the water is shallow and the wave amplitude rather large in comparison the speed of the waves depends on both the length and the amplitude As an incoming ocean wave approaches the beach the sea suddenly becomes shallow and nonlinear effects make the base of the wave slow up The result of colliding two solitary waves one would expect the humps whose stability depends upon a careful balance between nonlinear and dispersive effects to break up in collision Instead the two humps emerged from the disturbance intact and traveled with their original speeds The word soliton is invented to describe such humpsAs long as a medium is nonlinear it is likely to propagate pulses of energy in the form of solitons The actual medium where solitons propagate is irrelevant It may be a liuid solid gas electric current or a field such as electromagnetic field Another application is molecular biology It can be used to understand long chain molecules such as proteins or DNA Another area is superconductivity especially so called high temperature conductivity6 Solitons on the surface of water for example could be destroyed by making a large disturbance in the water By contrast some solitons can never be destroyed To understand the distinction imagina a stretched elastic colored blue on one side and red on the other If the elastic was nonlinear a solution could be produced by raising and releasing hump The energy is associated with the hump Because the hump can be flattened out again the soliton is not permanent However another type of soliton is possible on the strip This can be produced by a twist so that to the left of the twist the red side is uppermost while to the right the blue side is uppermost Although the twist can be slid back and forth along the strip there is no way that it can be untwisted if the strip is infinitely long There is also the possibility that this soliton could encounter an antisoliton consisting of a twist in the opposite direction moving along on the strip In this case the two solitons would annihilate each other and their energy would be converted to ordinary waves We can give an analogy of particle antiparticle annihilation for this case One example of area for topological solitons lies in particle physics Solitons appear as excitation of fields When a field is in its lowest energy state it is uniform throughout space Excitations arise when the field departs uniformity somewhere In a nonlinear field it can happen that as a result of the interaction of the field with itself that is the total energy is lower when the field is present with a finite strength This is because the effect of the field acting on itself reduces its energy In this case the field is still uniform but with a nonzero valuehttpsprofmattstrasslerfileswordpThere are two possibilites with zero field energy one with positive field strength or one with negative field strength the Higgs field can be given as an example of nonzero fields7 Newton s thought experiment Imagine a bucket of water suspended from a rope so that the bucket is free to spin Suppose the rope is strongly twisted and then released the bucket rotates At first the water remains unaffected Then as the rotation of bucket begins to influence the water inside viscous drag eventually the water also will be rotating at the same speed When the water rotates its surface will adopt a concave shape because of centrifugal force and if you stop the rotation of bucket for a time the water will continue to swirl around inside No reference is necessary to decide if the water is rotating because you can tell it simply by looking at the shape of its surface The curvature seems to depend upon absolute rotation of water relative to which Newton called absolute space Contemporary to Newton Gottfried Leibniz proclaimed that there is no space where there is no matter George Berkley also though the idea of absolute space is meaningless Ernest Mach refused to entertain the notion of unobservable absolute space and like Berkley he asserted both uniform and nonuniform motion were relative He explains the the centrifugal force comes from mass distribution in the universe For example we feel a centrifugal force if we rotate around ourselves and see the fixed stars rotate around ourselves If we didn t rotate and all the fixes rotated we d still feel the centrifugal force8 Apparent length of a broom depends on the angle you look at it in 3d space To get the true length you must add the suare of each three perpendicular apparent lengths In the case of 3d space1d time we must think the broom as a 4d object Suppose two events in space time and when one event occurred it emits a photon towards the location of other event Suppose when it arrived at the location the other event occurred In Minkowski Space timect 2 x 2 the distance of two events in space time is 0 and these events are called lightlike It is sometimes expressed by saying a photon visits all points along its path at the same moment9 If we imagine a free falling observer the fact that the observer is weightless it seems gravity can simply be transformed away by a change of reference frame However it is not because even in a falling elevator an observer could tell the Earth was exerting a gravitational pull because the Earth s gravity weakens with the suare of distance so the lower objects accelerate slightly faster than higher ones in a gravitational field Einstein realized that tidal forces cannot be transformed away by changing the reference frame He reasoned that the most satisfactory description of tidal forces is as a distortion or stretching space time itself John Wheeler expresses the link between space and time by saying Matter tells space how to bend space tells matter how to move Where Im Supposed To Be (Casey Book 1)
