+ +
When + What to do +
Jan 16-22 + Self teach some more scheme and differential geometry, documenting + examples. Maybe work through 2 or 3 problems from SICM textbook + or implement some classic physics problems (eg current through + wire cross section, variational principle examples in Feynman + lectures, derivation of magnetism at the 8.022 level). +
Understand and document scmutils package and compiler + interactions (at least conceptually). +
If I'm going to put mit-scheme in sage, this is the time to + do it, after this point I shouldn't be focusing on the software + tools as much. +
Jan 19-26? + Work through "Functional Differential Geometry", rewriting by hand +
Jan 31 + By this date have a proposed outline with length estimates so + I can sanity check with somebody in the physics department. +
Feb 28? + Have something resembling a draft and be working out details, + getting comments from professors and other students. At least + one interesting application should be demonstrated. +
??? + Spring break week +
??? + Final due to department +

Summary/Abstract

+from proposal: +

+I propose to implement a geometric formulation of curved space time in a +functional computer programming language, and to explore the space of +simulations +and manipulations made possible by such a formulation. A primary motivation +is to state the foundations of General Relativity in a non-ambiguous manner. +

+This work follows several attempts to formulate curved spacetime on +computers for the purpose of numerical calculations and algebraic manipulation. +Most of these packages are specially designed for the tasks of tensor analysis +and/or efficient numerical calculation, as is appropriate for use in +calculations. +A crucial difference of this proposed work will be to carefully build up the +geometric and analytical tools in a general purpose functional programing +language (mit-scheme). As a learning and reference tool, this will allow users +to explore +the inner workings and structure of the system, which I believe is essential to +understanding the system as a whole. +

+ The frame field representation will be used to emphasize the geometric +properties of curved space time, as opposed to the more traditional coordinate +heavy tensor analysis approach. +

+ The resulting work will include a full implementation with source code and +documentation, as well as example problems and qualitative comparisons with +existing packages and software systems. + diff --git a/references.html b/references.html index 5481396..7fc87ea 100644 --- a/references.html +++ b/references.html @@ -5,7 +5,7 @@ Bryan Newbold, bnewbold@mit.edu
