The First Law (1): Energy is Conserved in a closed system: . ... We usually consider work and heat flow as the two kinds of energy . The Second Law (2): The Law of Entropy: . ... The amount of disorder increases . ... You can not go from a disordered system to an ordered system without inputting more energy (this is the most important attribute of the second law) . ... In no way can we recover work of that this disordered system without putting energy into the system. ... More on Thermodynamics . ...

Here are some suggestions for subtracting Tiny Tim models from unsaturated WFPC2 PSFs. ... The undersampling of the WPFC2 cameras results in the observed PSF being highly dependent on positioning at the subpixel level. A subsampled model should be generated, shifted to match the proper positioning of the observed PSF, and then rebinned to detector sampling. ... The PSF models will never be perfect matches to the observed ones, and they will likely be too symmetrical. ... Figure 1. ...

Programs to generate color spectra ================================== These programs were developed to produce realistic color spectra from digital data. ... The distribution here contains the original source code for colorspec and solar in C, and a version of solar written in Fortran. ... It will produce a color spectrum of any digital spectrum. ... The 800x50 image solarflux.ppm was generated by colorspec and the file fluxatlas.dat, a reformatted NSO Solar Flux Atlas in the data directory. ...

The spatial distribution of stars in the Local Group dwarf irregular galaxy NGC 6822 has been studied, using recent positions and deep photometry for about 15,000 stars in the galaxy. Based on photometrical data, OB stars and red stars could be studied separately. Spatial statistical tools have been applied to the analysis of the spatial structure. ...

... ALMA . ... OOF software . ... Software . ... We present a framework for modelling atmospheric phase errors and their correction by both the fast-switching and water vapour radiometeric techniques. Notable features are simulating three dimensional turbulent volumes instead of flat phase screens, considering three representative configurations of ALMA and parametrisation in terms of phase fluctuations on a 300m baseline, allowing referencing to the site-testing interferometer data. ...

Here are a set of pictures which progress from the original through a couple intermediary images to the final, rather 60ish looking final image. This is the original image, created using some PD fonts and some mucking around with the BCG plug-in. The original logo has been extruded a bit using the displace plug-in. A web is created by using the wave plug-in, duplicating it and rotating it 180 degrees, and adding the two pieces together. The original logo is then placed over that. ...
