    Pi-Space Physics Software

    A Physics Theory for Unifying Classical, Quantum and Relativistic Phys

    This is the Official Software of the Pi-Space Physics Theory created by Martin Brady. I have a B.Sc. in Computer Applications from Dublin City University and I have an interest in software implementation of Physics. The Theory includes a Quantum Theory of Gravity as well as a reworking of Classical versions of Newton's Formulas. The Theory is based on a set of Relativistic Diagrams called Pi-Space Diagrams for those new to the Theory.

    Biogenesis Color Mod

    Mod for evolution simulation and artificial life program Biogenesis

    You can download the Color Mod at the Biogenesis main site too (included in the main download now). You also find the sourcecode there. If you want to post a review, remember that this is only a modification, so comment on my changes, not on the simulation. Original project by Joan Queralt Molina: https://sourceforge.net/projects/biogenesis/ Includes Tyler Colemans "Features Mod": https://sourceforge.net/projects/biogenesisfeatu/ Biogenesis discussion forum: https://sourceforge.net/p/biogenesis/discussion/ Biogenesis runs faster (at least for myself) if you open a Google Chrome window (don´t know why :D)
