Blackbody Radiation and the Scaling Symmetry of Relativistic Classical Electron Theory with Classical Electromagnetic Zero-Point Radiation

It is pointed out that relativistic classical electron theory with classical electromagnetic zero-point radiation has a scaling symmetry which is suitable for understanding the equilibrium behavior of classical thermal radiation at a spectrum other than the Rayleigh-Jeans spectrum. In relativistic classical electron theory, the masses of the particles are the only scale-giving parameters associated with mechanics while the action-angle variables are scale invariant. The theory thus separates the interaction of the action variables of matter and radiation from the scale-giving parameters. Classical zero-point radiation is invariant under scattering by the charged particles of relativistic classical electron theory. The basic ideas of the matter -radiation interaction are illustrated in a simple relativistic classical electromagnetic example.Comment: 18 page

Malthus Was Right After All: Poor Relief and Birth Rates in Southeastern England

The payment of child allowances to laborers with large families was widespread in early nineteenth-century England. This paper tests Thomas Malthus\u27s hypothesis that child allowances caused the birth rate to increase. A cross-sectional regression model is estimated to explain variations in birth rates across parishes in 1826-30. Birth rates are found to be related to child allowances, income, and the availability of housing, as Malthus contended. The paper concludes by examining the role played by the adoption of child allowances after 1795 in the fertility increase of the early nineteenth century

The Historical Background of the Communist Manifesto

[Excerpt] The Manifesto of the Communist Party, published 150 years ago in London in February 1848, is one of the most influential and widely-read documents of the past two centuries. The historian A. J. P. Taylor (1967, p. 7) has called it a holy book, and contends that because of it, everyone thinks differently about politics and society. And yet, despite its enormous influence in the 20th century, the Manifesto is very much a period piece, a document of what was called the hungry 1840s. It is hard to imagine it being written in any other decade of the 19th century. The critique of capitalism offered by Marx and Engels in the Manifesto is understandable in the context of economic conditions in Britain from 1837 to 1848, and it is not that different, in places, from the conclusions reached by other social critics during the 1840s. This paper attempts to place the Manifestos analysis of capitalist economic development in historical perspective. I begin by summarizing the economic arguments of Marx and Engels. While the Manifesto-was written by Marx, its economic analysis was strongly influenced by Engels\u27s practical experience of capitalism in his family\u27s cotton firm in Manchester, England, in 1842-44. Upon his return to Germany, Engels published in 1845 a scathing indictment of early industrial capitalism, The Condition of the Working Class in England. Much of Engels\u27s critique of British capitalism reappears in greatly condensed form in Section I of the Manifesto. The second part of the paper examines the economic, social, and political conditions in Manchester and the surrounding south Lancashire cotton towns in the 1830s and 1840s, drawing largely on the views of contemporary observers. I then look at recent research on the standard of living of the working class from 1820 to 1851, focusing on conditions in the Lancashire cotton industry during the hungry \u2740s. Finally, I examine economic conditions in England in the two or three decades after the Manifesto was published, and briefly discuss why Marx and Engels\u27s predictions for the imminent collapse of capitalism were so wide of the mark

[Review of the book \u3ci\u3eThe Scottish Poor Law, 1745-1845\u3c/i\u3e]

[Excerpt] While much has been written in the past 20 years concerning the Old Poor Law in England, very little attention has been given to the development of the Scottish Poor Law. This is surprising, given that the Scottish Poor Law differed radically from its English counterpart in its response to the increasing poverty of the late eighteenth and early nineteenth centuries. R. A. Cage\u27s descriptive account of the administration of the Poor Law in Scotland from 1745 to 1845 is therefore a welcome addition to the existing literature on the early development of the British social welfare system

Labour Migration in Southern and Eastern England, 1861-1901

This paper examines the determinants of migration from 19 southern counties to six major destinations in England and Wales from 1861-70 to 1891-1900. I find that, while the size of origin-destination wage gaps and the distance between origin and destination areas were important determinants of migration flows, as expected, migration was also strongly influenced by the number of previous migrants from an origin county living in a destination. The assistance provided by previous migrants to friends and relatives contemplating migration led to a perpetuation of earlier migration patterns, and helps to explain the continued dominance of London as a destination for migrants in the 1890s

Labor Economics

The authors hypothesize that most labor economists sooner or later had to incorporate at least the appearance of institutional concerns in their papers to avoid indigestion whenever lunching with colleagues outside the field of economics They add: If the new interests of modern labor economics are in fact driven by the imperatives of science, then the institutionalist and the neoclassical approaches may well synthesize

An experimental measurement of galactic cosmic radiation dose in conventional aircraft between San Francisco and London compared to theoretical values for conventional and supersonic aircraft

These direct measurements are in fair agreement with computations made using a program which considers both basic cosmic ray atmospheric physics and the focusing effect of the earth's magnetic field. These measurements also agree with those made at supersonic jet aircraft altitudes in Rb-57 aircraft. It is concluded that experiments and theory show that the doses received at conventional jet aircraft altitudes are slightly higher than those encountered in supersonic flights at much higher altitudes

The Blackbody Radiation Spectrum Follows from Zero-Point Radiation and the Structure of Relativistic Spacetime in Classical Physics

The analysis of this article is entirely within classical physics. Any attempt to describe nature within classical physics requires the presence of Lorentz-invariant classical electromagnetic zero-point radiation so as to account for the Casimir forces between parallel conducting plates at low temperatures. Furthermore, conformal symmetry carries solutions of Maxwell's equations into solutions. In an inertial frame, conformal symmetry leaves zero-point radiation invariant and does not connect it to non-zero-temperature; time-dilating conformal transformations carry the Lorentz-invariant zero-point radiation spectrum into zero-point radiation and carry the thermal radiation spectrum at non-zero temperature into thermal radiation at a different non-zero-temperature. However, in a non-inertial frame, a time-dilating conformal transformation carries classical zero-point radiation into thermal radiation at a finite non-zero-temperature. By taking the no-acceleration limit, one can obtain the Planck radiation spectrum for blackbody radiation in an inertial frame from the thermal radiation spectrum in an accelerating frame. Here this connection between zero-point radiation and thermal radiation is illustrated for a scalar radiation field in a Rindler frame undergoing relativistic uniform proper acceleration through flat spacetime in two spacetime dimensions. The analysis indicates that the Planck radiation spectrum for thermal radiation follows from zero-point radiation and the structure of relativistic spacetime in classical physics.Comment: 21 page

Unemployment and the UK Labour Market Before, During and After the Golden Age

During the ‘golden age’ of the 1950s and 1960s unemployment in Britain averaged 2 per cent. This was far lower than ever before or since and a number of hypotheses have been put forward to account for this unique period in labour market history. But there has been little attempt to isolate precisely how the determinants of wage setting and unemployment differed before, during and after the golden age. We estimate a two-equation model over the whole period from 1872 to 1999 using a newly constructed set of long-run labour market data. We find that the structure of real wage setting was different in the golden age, consistent with notions about the postwar consensus, but it did not result in wages that were significantly lower relative to productivity than during other eras. Rapid growth in productivity and world trade together with low interest rates did keep unemployment lower during the golden age than after the 1970s. But the key difference between the golden age and the periods before and after was shifts in labour demand that are not accounted for by any of the variables that are usually thought to determine the equilibrium unemployment rate
