We revisit the EPR problem and make clear what is a correct comprehension of its problem. When one applies the quantum mechanics correctly, it will be shown that there is no paradox. According to these lines of thought, a quantum teleportation scheme without resort to the von Neumann projection postulate is presented.

In lieu of an abstract, here is a brief excerpt of the content:Jesus, Man of Sin: Toward a New Christology in the Global EraSoho MachidaSin as the Common GroundThe blasphemous title of this article is likely to outrage more than a few devout Christians. I am aware that most Christians view Jesus as the most immaculate and beautiful person who ever lived. As a Buddhist scholar and practitioner, however, I cannot extinguish a long-held question from my mind. Was Jesus really (...) free from sin? I do not object to the view of those Christians who see him as the greatest living expression of compassion and courage. But the Christian construction of an untainted, perfect image of Jesus, the Son of God, raises certain problems that I would like to address. Although Jesus, the Anointed, could have had a special mission in the human world, the Son of Man did not appear as the Holy Ghost. He was incarnated in human form: “And the Word became flesh and dwelt among us, full of grace and truth; we have beheld his glory, glory as of the only son from the Father” (John 1:14).It is important to carefully consider the meaning of the Incarnation. The fact that Jesus came to be born with flesh in this world means that he chose to stand on the common ground of sin with us. The sin that I refer to here is the most ontologically fundamental sin that is at the core of human experience. What links us with Jesus is none other than so-called Original Sin.To be sure, as a man who comes from a different religious tradition, I do not make this outrageous claim because I want to dispute the value of the divine personhood of Jesus, or because I am cynical about the most sacred object of Christian faith. I have a deep respect for the greatness of the Christian tradition that has developed around this very unusual person, Jesus Christ.On a personal level too, I do not think of Jesus as a distant figure, as merely the god of another religion. During my boyhood in Japan, I often attended an Episcopal church; and the first academic degree I earned in the United States was in theological studies. In light of all that I have learned from my own personal involvement with Christianity, I still believe that Jesus was a person who suffered like us as a sinful human being.If I were to choose the most important of Jesus’ words from the Bible, I would not hesitate to point to the following passage: “Eloi, Eloi, lema sabachthani? (My God, my God, why have you deserted me?)” (Mark 15:34). It is surprising how few Christian scholars have offered persuasive interpretations of these words, which Jesus is said to have uttered in the final moments of his life. Many Christians would rather not hear such contradictory, despairing words come from the mouth of Jesus. Yet [End Page 81] these words of extreme suffering contain the key message at the core of Christian faith.Though I am also interested in Jesus’ historical background and the political role he played in a tiny corner of the Roman Empire, it is not the purpose of this article to investigate the historicity of Jesus’ life, as many theologians and historians have attempted to do in recent years. I will focus instead on the philosophical implications of Jesus’ life and his physical body, and why I believe it is important to develop a new Christology for the coming global era.The Karmic Body of JesusFirst, why did Jesus have to experience the suffering of crucifixion? The evident answer might be explained this way: because he sacrificed himself to redeem the human race, which has been sinning since the time of Adam and Eve. I would like, however, to suggest a totally different answer: Jesus was crucified to atone for his own sin. He courageously showed the way each of us must take responsibility for our own lives. He deserves our high admiration, but not excessive mystification.I do not mean that Jesus committed any specific sin in his lifetime, but rather that as the Son of Man he too was... (shrink)

Attention Restoration Theory proposes that exposure to natural environments helps to restore attention. For sustained attention—the ongoing application of focus to a task, the effect appears to be modest, and the underlying mechanisms of attention restoration remain unclear. Exposure to nature may improve attention performance through many means: modulation of alertness and one’s connection to nature were investigated here, in two separate studies. In both studies, participants performed the Sustained Attention to Response Task before and immediately after viewing a meadow, (...) ocean, or urban image for 40 s, and then completed the Perceived Restorativeness Scale. In Study 1, an eye-tracker recorded the participants’ tonic pupil diameter during the SARTs, providing a measure of alertness. In Study 2, the effects of connectedness to nature on SART performance and perceived restoration were studied. In both studies, the image viewed was not associated with participants’ sustained attention performance; both nature images were perceived as equally restorative, and more restorative than the urban image. The image viewed was not associated with changes in alertness. Connectedness to nature was not associated with sustained attention performance, but it did moderate the relation between viewing the natural images and perceived restorativeness; participants reporting a higher connection to nature also reported feeling more restored after viewing the nature, but not the urban, images. Dissociation was found between the physiological and behavioral measures and the perceived restorativeness of the images. The results suggest that restoration associated with nature exposure is not associated with modulation of alertness but is associated with connectedness with nature. (shrink)

The many-Hilbert-spaces theory of quantum measurements, which was originally proposed by S. Machida and the present author, is reviewed and developed. Dividing a typical quantum measurement in two successive steps, the first being responsible for spectral decomposition and the second for detection, we point out that the wave packet reduction by measurement takes place at the latter step, through interaction of an object system with one of the local systems of detectors. First we discuss the physics of the detection (...) process, using numerical simulations for a simple detector model, and then formulate a general theory of quantum measurements to give the wave packet reduction in an explicit form as a sort of phase transition. The derivation is based on the macroscopic nature of the local system, to be represented in a continuous direct sum of many Hilbert spaces, and on the finite-size effect of the local system, to give phase shifts proportional to size parameters. We give a definite criterion for examining any instrument as to whether it works well as a detector or not. Finally, we compare the present theory with famous measurement theories and propose a possible experimental test to discriminate it from others. A few solvable detector models are also discussed.

It is shown that the application of the Lax-Phillips scattering theory to quantum mechanics provides a natural framework for the realization of the ideas of the “Many-Hilbert-Space” theory of Machida and Namiki to describe the development of decoherence in the process of measurement. We show that if the quantum mechanical evolution is pointwise in time, then decoherence occurs only if the Hamiltonian is time-dependent. If the evolution is not pointwise in time (as in Liouville space), then the decoherence may (...) occur even for closed systems. These conclusions apply as well to the general problem of mixing of states. (shrink)
