Twin Paradox and Proper Time

Professors Mohazzbi and Luo [1] published “Despite several attempts have been made to explain the twin paradox … none of the explanations … resolved the paradox. If the paradox can be ever resolved, it requires a much deeper understanding … of the theory of relativity”. The deeper understanding of resolving the paradox is by applying more explicit definitions of proper time interval, Lorentz transform, time dilation, and aging time.

The Emergence of Time from Quantum Information Dynamics

This paper presents a novel framework for understanding time as an emergent phenomenon arising from quantum information dynamics. We propose that the flow of time and its directional arrow are intrinsically linked to the growth of quantum complexity and the evolution of entanglement entropy in physical systems. By integrating principles from quantum mechanics, information theory, and holography, we develop a comprehensive theory that explains how time can emerge from timeless quantum processes. Our approach unifies concepts from quantum mechanics, general relativity, and thermodynamics, providing new perspectives on longstanding puzzles such as the black hole information paradox and the arrow of time. We derive modified Friedmann equations that incorporate quantum information measures, offering novel insights into cosmic evolution and the nature of dark energy. The paper presents a series of experimental proposals to test key aspects of this theory, ranging from quantum simulations to cosmological observations. Our framework suggests a deeply information-theoretic view of the universe, challenging our understanding of the nature of reality and opening new avenues for technological applications in quantum computing and sensing. This work contributes to the ongoing quest for a unified theory of quantum gravity and information, potentially with far-reaching implications for our understanding of space, time, and the fundamental structure of the cosmos.

Space-Time Diagrams Lead to False Paradoxes

This paper provides a clear analysis of how hypothetical concepts not allowed in Special Relativity should be treated and exposes hidden assumptions in space-time diagrams used on YouTube, where some prominent physicists have taken to publishing on popular topics that may not survive peer review. Such casual graphical treatment conceals the fact that space-time diagrams provide only for the Einstein synchronization convention for all observers, not the many other valid synchronization protocols, and also obscure that relativity’s equality of reference frames is rebutted if concepts outside relativity, such as instant communication, are introduced. These omissions of unconscious assumptions have been used to “prove” the existence of block time and time travel or time paradoxes. We will show the contradictory assumptions amount to assuming time travel, rather than the more mundane need to adjust synchronization conventions. We further show a new result that the use of the space-time diagrams as proposed by these “explainers” leads to discontinuities in which a differential change in communication speed leads to a sudden jump from present to long-past arrival time, strongly suggesting invalidity of the method.

The solution of the time-dependent Fokker-Planck equation of non-degenerate optical parametric amplification and its application to the optimum realization of EPR paradox

In this paper, the solution of the time-dependent Fokker-Planck equation of non-degenerate optical parametric amplification is used to deduce the condition demonstrating the Einstein-Podolsky-Rosen （EPR） paradox. The analytics and numerical calculation show the influence of pump depletion on the error in the measurement of continuous variables. The optimum realization of EPR paradox can be achieved by adjusting the parameter of squeezing. This result is of practical importance when the realistic experimental conditions are taken into consideration .

Probability Distributions Arising in Connection with the Inspection Paradox for Bernoulli Trials

In renewal theory, the Inspection Paradox refers to the fact that an interarrival period in a renewal process which contains a fixed inspection time tends to be longer than one for the corresponding uninspected process. We focus on the paradox for Bernoulli trials. Probability distributions and moments for the lengths of the interarrival periods are derived for the inspected process, and we compare them to those for the uninspected case.

Probability Distributions Arising in Connection with the Inspection Paradox for the Poisson Process

The Inspection Paradox refers to the fact that in a Renewal Process, the length of the interarrival period which contains a fixed time is stochastically larger than the length of a typical interarrival period. To provide a more complete understanding of this phenomenon, conditioning arguments are used to obtain the distributions and moments of the lengths of the interarrival periods other than the one containing this fixed time for the case of the time-homogeneous Poisson Process. Distributions of the waiting times for events that occur both before and after this fixed time are derived. This provides a fairly complete probabilistic analysis of the Inspection Paradox.

数字化时代“时间悖论”与人的自由发展——基于马克思自由时间思想的考察

自由时间是人类真正自由的存在形式,不仅是人类发展的必要基础,而且是人的发展空间。数字技术通过变革生产节约必要劳动时间,创造出大量自由时间,为人的自由发展提供了更多可能性。然而,在当今资本主义社会,由于受数字资本逻辑支配,数字技术的运用悖谬性地加剧了时间异化,不仅出现了“劳动时间悖论”即劳动时间与自由时间在度上模糊,新型劳动时间同质化,而且导致了“发展时间悖论”即自由时间在质上变得消费化和娱乐化。有鉴于数字资本主义带来了这些“时间悖论”问题,中国特色社会主义在发展的过程中就要认真研究,必须坚持以人为本的科技发展理念,规范数字资本运作,完善劳动保障的伦理规范机制,建构生命尺度的主体时间观念,让数字中国充满时间正义,实现人的自由发展。

Two Strong Simple Proofs That All Doppler Shifts (including the Axial) Impact Observed Time, and All the Transverse Does

The first proof (Sections 2 - 4), applies Doppler shifts to the Fourier time sine series. It shows if K = f'/f (frequency ratio of the shift, f' the shifted frequency), then the value of the series at time = t occurs in the shifted series at time = t/K. That is because in each harmonic the sin(f't) and cos(f't) became sin(Kft) and cos(Kft). The original series could be the number of photons in area of a beam with encoded information. Therefore the number of observed photons and information has the same resultant Doppler shift as frequency. Resultant is total effect of axial, transverse and gravitational shifts. Mass and energy of light do not have the same Doppler shift which may indicate missing parts that Doppler shift and that mass traveling at the speed of light is different from other mass and energy. The second proof (Section 5) the vector equations of space time require observed time to have 3 dimensions if the speed of light is constant in all directions, but the Doppler shift in each direction is not the same. The blue shift (compression) of time has paradoxes. If time has many dimensions, that would solve the paradoxes, but break conservation laws. No solution of that is given here. It is not expected that radical a solution will have any followers.

Solvability of the Economic Input-Output Equation by Time Irreversibility

This paper reinterprets the economic input-output equation as a description of a realized situation without considering decision making. This paper uses the equation that the self-sufficiency rate is added to the Leontief type, and discusses its solvability. The equation has a unique solution if and only if each part of the relevant society satisfies the space-time openness condition. This condition means that commodities which a part of the relevant society possesses are not all inputted to its inside. Moreover, if the process of input and output is time irreversible, each part of the relevant society satisfies the space-time openness condition. Therefore, the solvability of the equation is guaranteed by time irreversibility. This proposition seems to be relevant to the grandfather paradox which is a type of time paradox.

The Twins Clock Paradox History and Perspectives

The twins or clock paradox has been a subject of lively discussion and occasional disagreement among both relativists and the public for over 100 years, and continues to attract physicists who write papers giving new analyses or defending old ones, even though many physicists now consider the matter only of educational interest. This paper investigates the number of papers, which is increasing, and trends in explanations, some of which are now targeted at professional physicists and other of which are targeted at optical or radar visualization rather than problem solving. Observations of students indicate that the latest techniques help but only somewhat. An analysis is made of 21 previous treatments appearing in the education related American Journal of Physics, Einstein’s discussions and several other pedagogical papers. A new memory aid for simultaneity transformation is given that puts it on a par with “time dilation” and “length contraction” for quick and easy problem visualization. The point of view of a trailing twin is introduced to show how simultaneity changes account for missing time in the turnaround. Length contraction is treated on equal footing with time dilation, and Swann’s insight into clocks is extended to lengths. Treatments using the conventionality of simultaneity are seen as equivalent to choice of co-moving frames. Responses to difficult questions are suggested which avoid being dismissive, and engage students’ critical thinking.

基于赋权奴役悖论,通过334名员工纵向数据分析,探究非工作时间工作连通行为对员工创造力的影响机理。结果表明:非工作时间工作连通行为对员工创造力存在“双刃剑”效应;工作进度位置控制和心理脱离在其中发挥中介作用;多重任务倾向负向调节非工作时间工作连通行为对心理脱离的消极作用,以及心理脱离在非工作时间工作连通行为与员工创造力之间的中介作用;多重任务倾向正向调节非工作时间工作连通行为对工作进度位置控制的积极作用,以及工作进度位置控制在非工作时间工作连通行为与员工创造力之间的中介作用。

基于证据一致性检验的目标属性序贯辨识

针对信息不确定、不完备引起的识别证据动态变化、冲突悖论等问题,提出了一种基于证据一致性检验的目标属性序贯辨识改进方法。首先采用顺序滑动窗口构建时序证据体,再通过证据一致性检验,快速定位冲突证据并动态重构出一致性证据体,最后利用证据理论合成获得目标序贯辨识结果。经仿真数据验证表明,该方法能有效积累时序证据能量、抑制冲突悖论,提高目标属性辨识的准确性和稳定性。

去悖论叙事:新主流电影中叙事的“第三种选择”

新主流电影不再简单延续传统主旋律电影中“为国家牺牲小家,为集体牺牲个体”的压抑性叙事策略,而是营造对观众充满吸引力的戏剧性“道德悖论”困境,之后运用“去悖论叙事”手法使悖论危机获得圆满化解,帮助观众的压迫心理得到想象性释放,最终实现意识形态主题的顺畅表达。以艺术伦理学范畴内的“叙事伦理”切入分析,新主流电影主要选择以“情节叙事性”“人民伦理性”两种“去悖论叙事”方法,从传统主旋律影片“非此即彼”的道德悖论困境中成功抽离,潜移默化间完成了新主流电影“角色-观众”间审美的隐性置换。

大卫·哈维的“时空修复机制”与当代资本主义的悖反性研究

马克思、恩格斯早在一百多年前就作出“资产阶级必然灭亡、无产阶级必然胜利”的理论预判,然而当代资本主义非但没有灭亡,还迎来了一个相对稳定的发展时期,这是否是对马克思主义理论的证伪?哈维从马克思主义的基本立场出发,建构了“时空修复机制”的系统理论,探究了时空修复化解当代资本主义危机的运行机制及其局限性。这既为当代资本主义的幸存提供了解释力,也揭示了“时空修复机制”与当代资本主义的悖反性,进而从马克思主义的批判视域接续论证了当代资本主义必然灭亡的历史命运。革命性的科学理论必将在现实中得到印证,新民粹主义和逆全球化思潮的兴起,实质是大卫·哈维的“第二块危机理论”和“第三块危机理论”在当代资本主义新变化中的初步应验,揭露了“时空修复机制”内在否定的发展趋势。

松约束运输问题的三角形回路算法

运输问题存在“多反而少”现象,这是由于在松约束模型中放宽了约束条件,使得可行域变大,产生了新的最优解。传统的松约束模型的解法,是在表上作业法的基础上,先求得对应紧约束模型的最优解,再进行调整。论文介绍了一种完全独立于紧约束模型的算法,并分析了该算法的正确性,最后对相同参数的紧约束和松约束模型的最优解进行比较,从而验证了算法的潜在实用价值。

大数据系统实施对企业绩效影响的实证研究

以66家实施了大数据系统的上市企业为样本对象,通过t检验和Wilcoxon秩和检验,分析大数据系统实施对企业营运绩效和盈利绩效的影响。研究结果表明,在大数据系统实施当年,企业库存周转率和销售净利率不升反降,但在系统实施后1~2年均显著增长;总资产周转率在实施当年和实施后第1年为负增长,而在实施后第2年正向增长但不显著;总资产报酬率在大数据系统实施后2年没有提升。总资产周转率和总资产报酬率在系统实施后2年均未明显提高的原因可能在于,大数据系统实施的巨额成本对企业利润具有分摊效应。

确定性的丧失——20世纪新启蒙运动的来龙去脉

近代启蒙运动从探讨人性出发追求科学与理性,在学理上表现为对于形式上的确定性的高度肯定。但是,作为重要启蒙思想家的卢梭,发现了"不确定性"在启蒙思想所讨论的各种问题上的意义,之后的叔本华、尼采、克尔恺郭尔,延续了卢梭所开辟的这个方向,这些思想的精华成为20世纪后现代思潮的精神灵感的重要来源,并且在数学、逻辑、自然科学领域得到了验证。20世纪新启蒙运动与近代启蒙运动类似,也是一场跨学科的、对人类文明发展产生了重大影响的思想-社会运动。它指出了近代启蒙运动的局限性,探讨了人性新的可能性,使人类走向一个更为宽容和开放的时代。
