Mieczysław Wolfke - a pioneer of holography

Receiving the Nobel Prize in 1971 for the invention and development of the holographic method, Dennis Gabor mentioned Mieczysław Wolfke as the person who proposed this method as early as 1920 (which he did not know, independently making the same discovery). This article describes the history of Wolfke's pioneering work and tries to recreate the thought process that led to it - starting with the task of supplementing and verifying the diffraction grating theory proposed by Ernst Abbe, which he carried out as part of his doctorate at the University of Wrocław and habilitation at the University of Zurich and the Swiss Federal Institute of Technology in Zurich..

The Case Against Smooth Null Infinity I: Heuristics and Counter-Examples

This paper initiates a series of works dedicated to the rigorous study of the precise structure of gravitational radiation near infinity. We begin with a brief review of an argument due to Christodoulou (in: The Ninth Marcel Grossmann Meeting, World Scientific Publishing Company, Singapore, 2002) stating that Penrose’s proposal of smooth conformal compactification of spacetime (or smooth null infinity) fails to accurately capture the structure of gravitational radiation emitted by N infalling masses coming from past timelike infinity $$i^-$$ i - . Modelling gravitational radiation by scalar radiation, we then take a first step towards a dynamical understanding of the non-smoothness of null infinity by constructing solutions to the spherically symmetric Einstein–Scalar field equations that arise from polynomially decaying boundary data, $$r\phi \sim t^{-1}$$ r ϕ ∼ t - 1 as $$t\rightarrow -\infty $$ t → - ∞ , on a timelike hypersurface (to be thought of as the surface of a star) and the no incoming radiation condition, $$r\partial _v\phi =0$$ r ∂ v ϕ = 0 , on past null infinity. We show that if the initial Hawking mass at $$i^-$$ i - is nonzero, then, in accordance with the non-smoothness of $${\mathcal {I}}^+$$ I + , the asymptotic expansion of $$\partial _v(r\phi )$$ ∂ v ( r ϕ ) near $${\mathcal {I}}^+$$ I + reads $$\partial _v(r\phi )=Cr^{-3}\log r+{\mathcal {O}}(r^{-3})$$ ∂ v ( r ϕ ) = C r - 3 log r + O ( r - 3 ) for some non-vanishing constant C. In fact, the same logarithmic terms appear already in the linear theory, i.e. when considering the spherically symmetric linear wave equation on a fixed Schwarzschild background. As a corollary, we can apply our results to the scattering problem on Schwarzschild: Putting compactly supported scattering data for the linear (or coupled) wave equation on $${\mathcal {I}}^-$$ I - and on $${\mathcal {H}}^-$$ H - , we find that the asymptotic expansion of $$\partial _v(r\phi )$$ ∂ v ( r ϕ ) near $${\mathcal {I}}^+$$ I + generically contains logarithmic terms at second order, i.e. at order $$r^{-4}\log r$$ r - 4 log r .

Review of "Ethics of Chemistry: From Poison Gas to Climate Engineering" by Joachim Schummer & Tom Børsen, eds. World Scientific Publishing, Singapore, 2021

BRINGING THE ETHICS OF CHEMISTRY TO THE CLASSROOM AND THE EXISTENCE OF A DOMAIN OF KNOWLEDGE Whoever has attempted to bring ethical discussions on chemistry to a student audience of chemistry and related fields knows of the problem: in contrast to the relatively robust bioethical literature, the literature of chemical ethics is poor, disconnected, and scattered all around the place even in rare cases that it exists. This is an interesting fact, especially if one considers the extended moral (and moralist) discussions over chemistry and its products, and that a great part of the bioethical challenges of the last forty years or so have been generated not by biology (or medicine) per se, but from their marriage to chemistry and its practices. The lack of ethics of chemistry literature dictates to the lecturer unprecedented levels of creativity and demands extra workload to be effective –and this, in times where ethics courses, in general, have become a necessity. It is this gap that the editors of this book (Schummer and Børsen, Ethics of Chemistry: From Poison Gas to Climate Engineering, World Scientific, 2021) have detected, and they strove to create a collection of case studies to cover it. In the introduction of the volume, the editors state teaching as the first aim of its existence –and add the establishment of the ethics of chemistry as an autonomous discipline in its own right.
