Herbert Gleiter promoted the development of nanostructured materials on a variety of levels. In 1981 already, he formulated research visions and produced experimental as well as theoretical results. Still he is known only to a small community of materials scientists. That this is so is itself a telling feature of the imagined community of nanoscale research. After establishing the plausibility of the claim that Herbert Gleiter provided a major impetus, a second step will show just how (...) deeply Gleiter shaped (and ceased to influence) the vision of the National Nanotechnology Initiative in the US. Finally, then, the apparent invisibility of Gleiter's importance needs to be understood. This leads to the main question of this investigation. Though materials research meets even the more stringent definitions of nanotechnology, there remains a systematic tension between materials science and the device-centered visions of nanotechnology. Though it turned the tables on the scientific prestige of physics, materials science runs up against the engineering prestige of the machine. (shrink)

We consider various effects that are encountered in matter wave interference experiments with massive nanoparticles. The text-book example of far-field interference at a grating is compared with diffraction into the dark field behind an opaque aperture, commonly designated as Poisson’s spot or the spot of Arago. Our estimates indicate that both phenomena may still be observed in a mass range exceeding present-day experiments by at least two orders of magnitude. They both require, however, the development of sufficiently cold, intense and (...) coherent cluster beams. While the observation of Poisson’s spot offers the advantage of non-dispersiveness and a simple distinction between classical and quantum fringes in the absence of particle wall interactions, van der Waals forces may severely limit the distinguishability between genuine quantum wave diffraction and classically explicable spots already for moderately polarizable objects and diffraction elements as thin as 100 nm.

This volume consists of a collection of articles published by Spencer in leading Victorian periodicals, such as The Westminster Review, The Fortnightly Review and Mind. The wide range of subjects explored includes science, philosophy, aesthetics, ethics, psychology and politics.

Before they can commit their states to war, leaders who believe that war is necessary must first secure public commitment to collective action and sacrifice. The chief instrument for achieving this...

§ . As a corollary to the proposition that all institutions must be subordinated to the law of equal freedom, we cannot choose but admit the right of the citizen to adopt a condition of voluntary outlawry. If every man has freedom to do all that he wills, provided he infringes not the equal freedom of any other man, then he is free to drop connection with the state - to relinquish its protection and to refuse paying toward its support. (...) It is self evident that in so behaving he in no way trenches upon the liberty of others, for his position is a passive one, and while passive he cannot become an aggressor. It is equally self evident that he cannot be compelled to continue one of a political corporation without a breach of the moral law, seeing that citizenship involves payment of taxes; and the taking away of a man's property against his will is an infringement of his rights. Government being simply an agent employed in common by a number of individuals to secure to them certain advantages, the very nature of the connection implies that it is for each to say whether he will employ such an agent or not. If anyone of them determines to ignore this mutual safety confederation, nothing can be said except that he loses all claim to its good offices and exposes himself to the danger of maltreatment - a thing he is quite at liberty to do if he likes. He cannot be coerced into political combination without a breach of the law of equal freedom; he can withdraw from it without committing any such breach, and he has therefore a right so to withdraw.

A convenient and practical method is presented for the generation of unbiased random sequences. The method is based on combining discrete outputs and does not require either precisely specified and unbiased input or complex procedures and equipment.

Even those who are unfamiliar with Aquinas will find this book gripping. Published posthumously, this study is thoroughly rewarding and will increase McCabe's reputation as one of Britain's finest theologians of recent years.

This Introduction describes the approach and rules applied when translating a 25-page excerpt from Marx’s Manuscript of 1867–68, as published in the MEGA, Volume II/4.3. The draft status and terseness of the text required that the translation proceed along with a working-out of its mathematical content. The translation’s main guideline was to translate the draft such as it stood, while correcting figures and formulas wherever possible. Remaining major deficiencies and inconsistencies are discussed in depth, showing also what an outstanding level (...) of acuity Marx had already achieved in a manuscript at first-draft stage.

A new interpretation of thermodynamics is advanced; thermodynamics is the study of those properties of macroscopic matter that follow from the symmetry properties of physical laws, mediated through the statistics of large systems.

In Executive Order No. 10521, March 17, 1954, President Eisenhower stated: “…only a small fraction of the Federal Funds is being used to stimulate and support the vital basic research which makes possible our practical scientific progress. I believe strongly that this Nation must extend its support of research in basic science.”.

This paper considers reductions between types of numberings; these reductions preserve the Rogers Semilattice of the numberings reduced and also preserve the number of minimal and positive degrees in their semilattice. It is shown how to use these reductions to simplify some constructions of specific semilattices. Furthermore, it is shown that for the basic types of numberings, one can reduce the left-r.e. numberings to the r.e. numberings and the k-r.e. numberings to the k+1-r.e. numberings; all further reductions are obtained by (...) concatenating these reductions.
