    Conventional rockets are not a suitable technology for interstellar missions. Chemical rockets require a very large weight of propellant, travel very slowly compared to light speed, and require significant energy to maintain operation over periods of years. For example, the 722 kg Voyager spacecraft required 13,600 kg of propellant to launch and would take about 80,000 years to reach the nearest star, Proxima Centauri, about 4.3 light years away. There have been various attempts at developing ideas on which one (...)

    By setting out the grammar of event causality, as developed by Hume and Mackie, in contrast to the grammar of agent causality in the natural sciences, a kind of hybrid hierarchical format for chemical explanations is sketched. From this starting point the history of agentive concepts in chemistry is displayed as a progression from Newton’s ‘forces’, through the nineteenth century concepts of ‘affinity’ and ‘valency’ to recent theories of molecular binding in terms of the migration of electrons and protons as (...)

    This history of physics focuses on the question, "How do bodies act on one another across space?" The variety of answers illustrates the function of fundamental analogies or models in physics as well as the role of so-called unobservable entities. Forces and Fields presents an in-depth look at the science of ancient Greece, and it examines the influence of antique philosophy on seventeenth-century thought. Additional topics embrace many elements of modern physics--the empirical basis of quantum mechanics, wave-particle duality and the (...)

    One of the major reasons underlying the widespread rejection of the theory that the mind is an immaterial substance distinct from the body, But which nevertheless acts on the body, Is that it is felt that such a theory commits one to denying the principle of the conservation of energy. My aim in this article is to assess the strength of this objection. My thesis is that the usual replies are inadequate, But--Strong as this objection appears--Some important logical distinctions (...)

    Research progress assessing the role of attentional focusing instructions on skill acquisition and performance has lead researchers to apply this approach to force production tasks. Initial converging evidence indicates that force production tasks are sensitive to verbal instruction; externally focused instructions (onto movement outcomes, or onto the object force is being exerted against) are shown to be more beneficial than internally focused instructions (focusing attention onto the movements being executed). These benefits are observed for maximal and accurate (...)

    Zeilinger's observation that phenomena of the Aharonov-Bohm type lead to non-dispersive, i.e., energy-independent, phase shifts in interferometers is generalized in a new proof which shows that the precise condition for nondispersivity is a force-free interaction. The converse theorem is disproved by a conceptual counter-example. Applications to several nondispersive interference phenomena are reviewed briefly. Those fall into two classes which are objectively distinct from each other in that in the first class phase shifts depend only on the topology of (...)

    The vacuum structure for the massive charged scalar field in the region of two parallel, infinitely long and thin solenoids confining the fluxesn 1 andn 2 is studied. By using the Green function method, it is found that the vacuum expectation value of the system's energy has a finite mutual interaction term depending on the distance a between the solenoids, which implies an attractive force per unit length given by F n1n2 =−(ℏc/π2)(n 1 n 2)2/a 3.

    Abstract In this paper, we show that Greek distinguishes empirically ability as a precondition for action, and ability as initiating and sustaining force for action. In this latter case, the ability verb behaves like an action verb, and the sentence has the logical form of a causative structure φ CAUSE [BECOME ψ] (Dowty 1979). The distinction between ability as potential for action and ability as action itself has a venerable tradition that goes back to Aristotle, and is recently implied (...)

    Wenqi 文氣 (literary pneuma) is a foundational idea in Chinese aesthetics. It has remained elusive since its initial formulation, however. This is so largely because previous scholars did not examine its ontological and epistemological conditions in analytic terms, still less explore its implications in a conceptual framework of artistic creation. Here, it is proposed to explore its general as well as specific implications against the larger background of Chinese intellectual thought and in relation to contemporary theories of literature and aesthetics.

    A new scheme is proposed in order to deduce an equation of motion for a spinless charged point particle leading to an equivalent Landau–Lifshitz equation of motion. Consequently Larmor’s formula must be substituted by a new expression for the large distance radiation rate of energy. A constraint appears on the applicability of the Maxwell electromagnetic tensor. The particular case of a sudden force is analyzed in order to show the physical results predicted by the new model. A geometrical (...)

    In order to assess the tenacity of psychoanalysts in continuing to use a concept of psychic energy, it is advisable to consider whether, as they sometimes claim, the concepts of energy, force, and work in psychoanalysis are akin to those in the natural sciences. Strong disanalogies suggest that the psychoanalytic concepts are quite different and used equivocally even within psychoanalysis. However, they may not be subject to the objections which certain critical psychoanalysts have raised.

    According to history texts, philosophers searched for a unifying natural law whereby natural phenomena and numbers are related. More than 2300 years ago, Aristotle postulated that nature requires minimum energy. More than 220 years ago, Euler applied the minimum energy postulate. More than 200 years ago, Lagrange provided a mathematical “proof” of the postulate for conservative systems. The resulting Principle of Least Action served only to derive the differential equations of motion of a conservative system. Then, 170 years (...)

    For over a century the definitions of mass and derivations of its relation with energy continue to be elaborated, demonstrating that the concept of mass is still not satisfactorily understood. The aim of this study is to show that, starting from the properties of Minkowski spacetime and from the principle of least action, energy expresses the property of inertia of a body. This implies that inertial mass can only be the object of a definition—the so called mass-energy (...)

    In this paper we pay attention to the inconsistency in the derivation of the symmetric electromagnetic energy–momentum tensor for a system of charged particles from its canonical form, when the homogeneous Maxwell’s equations are applied to the symmetrizing gauge transformation, while the non-homogeneous Maxwell’s equations are used to obtain the motional equation. Applying the appropriate non-homogeneous Maxwell’s equations to both operations, we obtained an additional symmetric term in the tensor, named as “compensating term”. Analyzing the structure of this “compensating (...)

    In the mid-2000s, rising gas prices, political instability, pollution, and fossil fuel depletion brought renewable domestic energy production onto the policy agenda. Biofuels, or fuels made from plant materials, came to be seen as America’s hope for energy security, environmental conservation, and rural economic revitalization. Yet even as the actual environmental, economic, and energy contributions of a biofuels boom remained debatable, support for biofuels swelled and became a prominent driver of not only US energy policy but (...)

    Examining the process of action at a distance, we arrive at the following conclusions: (a) The virtual photons and mesons transmitting Coulomb and nuclear forces, respectively, do not arise from “temporary violations of energy conservation,” but, on the contrary, exactly embody the potential energy corresponding to the relevant forceF that they transmit on their collision with the charged particles or nucleons via the formula Δp=FΔt.

We reiterate the notion that illusory percepts are, in fact, Bayes-optimal and represent the most likely explanation for ambiguous sensory input. This point is illustrated using perhaps the simplest of visual illusions; namely, the Cornsweet effect. By using plausible prior beliefs about the spatial gradients of luminance and reflectance in the visual world, we show that the Cornsweet effect emerges as a natural consequence (...)

    Curiously, in some ways gravity is also the strongest force in the universe. It always adds, never subtracts, and can build up until it overwhelms all other forces.. In normal stars gravity is balanced by heat energy from fusion reactions in the star's core. Eventually, however, the hydrogen and heavier elements fueling these reactions are used up, gravity takes over, and the star collapses in on itself. The result is a supernova explosion, which converts a sizable fraction of (...)
