    Jonathan Edwards\u27 Life: More Than a Sermon

    Get PDF
    Jonathan Edwards, born, (1703-1758), was a great man. He is often known only for a sermon, Sinners in the Hands of an Angry God. This is unfortunate because followers of Christ should know this man\u27s life. This paper focuses on Jonathan Edwards as a godly family man and on his missiological work. An emphasis is not carefully analyzed by many. The research for this essay originated from the author\u27s desire to know more about Mr. Edwards. The texts studied are The works of Jonathan Edwards, along with many scholarly books and essays. The main modern books used are from Perry Miller and Elizabeth Dodds. All in all, the following research adds clarity and context to Edwards\u27 legacy and to its enduring value to Christians

    Recircumscription of the Nepenthes alata group (Caryophyllales: Nepenthaceae) in the Philippines : with four new species

    Get PDF
    An overview of Nepenthes in the Philippines is presented. Four new species, Nepenthes extincta sp. nov., N. kitanglad sp. nov., N. kurata sp. nov. and N. leyte sp. nov. are described and illustrated from the Philippines and placed in the Nepenthes alata group. An updated circumscription and key to the species of the group is provided. Delimitation and comparison with the Regiae group is given. All four of the newly described species are assessed as threatened using the International Union for the Conservation of Nature 2012 standard, and one, N. extincta sp. nov. is considered likely to be already extinct due to open-cast mining. Logging and conversion of forest habitat are thought to be the main threats to the other three species

    Cosmological perturbation theory in 1+1 dimensions

    Many recent studies have highlighted certain failures of the standard Eulerian-space cosmological perturbation theory (SPT). Its problems include (1) not capturing large-scale bulk flows [leading to an O(1) error in the 1-loop SPT prediction for the baryon acoustic peak in the correlation function], (2) assuming that the Universe behaves as a pressureless, inviscid fluid, and (3) treating fluctuations on scales that are non-perturbative as if they were. Recent studies have highlighted the successes of perturbation theory in Lagrangian space or theories that solve equations for the effective dynamics of smoothed fields. Both approaches mitigate some or all of the aforementioned issues with SPT. We discuss these physical developments by specializing to the simplified 1D case of gravitationally interacting sheets, which allows us to substantially reduces the analytic overhead and still (as we show) maintain many of the same behaviors as in 3D. In 1D, linear-order Lagrangian perturbation theory ("the Zeldovich approximation") is exact up to shell crossing, and we prove that n^{th}-order Eulerian perturbation theory converges to the Zeldovich approximation as n goes to infinity. In no 1D cosmology that we consider (including a CDM-like case and power-law models) do these theories describe accurately the matter power spectrum on any mildly nonlinear scale. We find that theories based on effective equations are much more successful at describing the dynamics. Finally, we discuss many topics that have recently appeared in the perturbation theory literature such as beat coupling, the shift and smearing of the baryon acoustic oscillation feature, and the advantages of Fourier versus configuration space. Our simplified 1D case serves as an intuitive review of these perturbation theory results.Comment: 28 pages + appendices; 10 figures; matches version accepted to JCA
