+						  EDWIN CHEAT SHEET

+					   (keep under your pillow)

+

+						   6.090, IAP 2005

+

+Reading Edwin key combinations:

+	C-x									Ctrl+x

+	M-x									Alt+x

+	C-x, y								Ctrl+x, release both, y

+	C-M-x								Ctrl+Alt+x

+

+Stuff You *Need* to Know:

+	Starting Edwin						Start Menu > MIT Scheme > Edwin

+	Quitting Edwin						C-x, C-c

+	Opening a file						C-x, C-f

+	Closing a file (aka buffer)			C-x, k

+	Evaluate current expression 		C-x, C-e

+	(expression ending just before 

+	insertion point)

+	Evaluate entire buffer

+	(works only on Scheme files!)		M-o

+

+The Edwin Window and Scheme:

+	When you start it, the Edwin window looks like a plain text

+	editor. It has a large blank area for entering text, one black

+	line at the bottom with some information displayed (the modeline),

+	and a blank white line below that (the minibuffer). 

+

+	The text area

+		is where the file you're viewing shows up. You can edit the

+		file here, with the usual keys (up, down, page up, left... you

+		get the idea).

+

+	The modeline

+		displays the name of the current buffer (file), your position

+		in it, and the kind of file Edwin thinks it is (text, scheme

+		code etc.).

+

+	The minibuffer 

+		is where you interact with Edwin's commands. For example, when

+		you press C-x, C-f to open a file, you enter the filename in

+		the minibuffer.

+

+	Edwin is more than just an editor, though. It also features a

+	Scheme evaluator, to which it can send your code. So when you

+	press C-x, C-e at the end of an expression, it gets evaluated by

+	this evaluator (more on evaluators and evaluation in class).

+

+	Try out the key combinations below to see what they do. Don't try

+	to memorize them. Your finger muscles will learn them as time goes

+	on :-)

+

+Inessential Edwin:

+							   Editing

+	Marking/selecting text				Go to one end of the block, press 

+					  					C-space, go to the other end. You won't

+										see any visual indication of the 

+										selection.

+	Cut									C-w

+	Copy								M-w

+	Paste								C-y

+	Cut from point to end of like		C-k

+

+					 Multiple Windows and Buffers

+	Switch buffer	 		  		  	C-x, b

+	Switch window						C-x, o

+	Split window vertically				C-x, 2

+	Split window horizontally			C-x, 3

+	Delete current split				C-x, 0

+	Create new frame (window)			C-x, 5, 2

+	Delete current frame				C-x, 5, 0

+

+Interactive Scheme:

+	When you are in the buffer called *scheme*, everything you type goes

+	directly to the evaluator, and the results are displayed below your

+	expressions. When you make an error, the evaluator gives you a set of

+	choices to help you debug your code. Usually, it is best to type (restart 1)

+	at the next prompt to abort the current evaluation, so you can go back and

+	examine your code to see what went wrong. For more advanced debugging tools,

+	talk to an LA.

+\begin_layout Quotation
+Advisor: Prof.
+ Gerald J.
+ Sussman, EECS
+\end_layout
+
+\begin_layout Standard
+I propose to implement a geometric formulation of curved space time in a
+ functional computer programming language, and to explore the space of simulatio
+ns and manipulations made possible by such a formulation.
+ A primary motivation is to state the foundations of General Relativity
+ in a non-ambiguous manner.
+ 
+\end_layout
+
+\begin_layout Standard
+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 calculatio
+ns.
+ 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.
+ 
+\end_layout
+
+\begin_layout Standard
+The frame field representation will be used to emphasize the geometric propertie
+s of curved space time, as opposed to the more traditional coordinate heavy
+ tensor analysis approach.
+\end_layout
+
+\begin_layout Standard
+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.

+<h2>Informal Background</h2>
+For the fall of 2008 I'm very interested in investigating gravitation and 
+other physical theories using functional programming techniques. I find that
+formalizing physical systems into a computer model is the best way to solidify
+my understanding of the system; using functional languages and techniques
+makes the conceptual wall between mathematical abstraction and programming
+implementation much lower; the result is a more reusable and general model 
+well suited for experimentation and exploration.
+<br /> <br />
+I am planning on getting my undergraduate physics degree in spring 2009, for
+which I will need a thesis. I am hoping to develop skills and tools this fall
+with which to accomplish Real Live Science over IAP and in the early spring.
+<br /><br />
+The stimulus for this course of study was the class 
+<a href="http://www-swiss.ai.mit.edu/~gjs/6946/index.html">Classical 
+Mechanics: A Computational Approach</a> taught by G. Sussman and J. Wisdom
+at <a href="http://web.mit.edu">MIT</a>. I had trouble with the later sections
+of the book/course and am hoping that now with an eta of math under my belt I
+can chip away at it.
+
+<h2>Potential Fall Projects</h2> 
+
+<b>Integration of mit-scheme and scmutils into Sage</b>
+<span style="font-weight:bold; color:#00CC00;">(yes)</span>
+<br />The <a href="http://sagemath.org">Sage math system</a> is an open-source 
+alternative to Mathematica, Maple, etc. It provides an easy to learn html 
+notebook interface (as well as command line) and is bundled with a plethora 
+of high performance libraries (like PARI, GMP, MAXIMA, SINGULAR, see this 
+<a href="http://www.sagemath.org/packages/standard/">list</a>).  <br />
+A number of other packages (including common lisp) already have interfaces
+based around a fake TTY device; this should be easy with mit-scheme. Or a more
+complete object-style interface could be implemented. There is documentation
+for writing interfaces <a href="http://www.sagemath.org/doc/prog/prog.html">
+here</a> and <a href="http://www.sagemath.org/doc/ref/node95.html">here</a>
+<br />
+There is a public demo server at <a href="http://sagenb.org">sagenb.org</a>, 
+but it's usually slow. Try this 
+<a href="https://sage.math.washington.edu:8102/">server</a> instead (user:
+ableseaman, password: bottlerum, if you don't want to fill out the form).
+Sage has been used in math classes at MIT already; Tim Abbot is working
+on "debianizing" the whole system, after which it should be on Athena.
+<br /><br />
+
+<b>Exploration of "higher order dynamics"</b>
+<span style="font-weight:bold; color:orange;">(possible)</span>
+<br />
+I'd like to play with systems involving "higher order dynamics", aka {jerk,
+yank, <a href="http://sprott.physics.wisc.edu/pubs/paper229.pdf">snap, crackle, pop</a>}. These dynamics have become interesting to cosmologists?
+<br />See arxiv <a href="http://arxiv.org/abs/gr-qc/0309109">one</a>, <a href="http://arxiv.org/abs/astro-ph/0408279">two</a>, other chaotic <a href="http://sprott.physics.wisc.edu/pubs/paper229.pdf">pdf</a>.
+<br /><br />
+
+<b>General Relativity Simulations: compact bodies, inspirals, precession</b> 
+<span style="font-weight:bold; color:orange;">(possible)</span>
+<br />Should talk with <a href="http://gravity.psu.edu/people/LSF/">Lee Finn
+</a>@penn, <a href="http://mit.edu/pranesh/www/">pranesh</a>@mit? Go to 
+<a href="http://space.mit.edu/journalclub/index.html">mki journal club</a>.
+<br /> <br />
+
+<b>Modified Newtonian Dynamics</b> 
+<span style="font-weight:bold; color:orange;">(possible)</span>
+<br /><a href="http://en.wikipedia.org/wiki/Modified_Newtonian_dynamics">MOND</a>
+was originally proposed to explain the galactic rotation curve
+problem; it has been extended as a relativistic field theory as 
+<a href="http://en.wikipedia.org/wiki/Tensor-vector-scalar_gravity">TeVeS</a> 
+(Tensor-vector-scalar gravity, described in 2004).
+<br />
+I think it would be interesting to implement and play with MOND or other 
+alternative gravitational theories in a symbolic computation framework. 
+Assumptions could be checked quickly and easily (eg, behaves like X in the
+short distance limit, behaves like Y in the high stress-energy limit). 
+The process of formalization could also be a good test; if the theory can't
+be coded, is it a valid theory? Would also demonstrate that programming tools 
+are general and can be used to explore non-physical theories.
+<br />See also Henon-Heiles.
+<br /> <br />
+
+<b>Action Minimization Problems</b>
+<span style="font-weight:bold; color:orange;">(possible)</span>
+<br />
+Minimization of action over path integrals is a classic hammer in the physics
+toolbox (everything looks like an oscillating nail). It might be fun to 
+play with some old classics like optics or Ohm-ic resistance.
+<br /><br />
+
+<b>Basic Quantum Mechanics</b> 
+<span style="font-weight:bold; color:red;">(unlikely)</span>
+<br />Methods with Wilkson-Sommerfeld quantization? I don't know enough 
+QM to go beyond simple, introductory quantum systems, but might be interesting.
+<br /><br />
+
+<b>Quantum Computation</b>
+<span style="font-weight:bold; color:red;">(unlikely)</span>
+<br />There is already extensive work done here; see 
+<a href="http://tph.tuwien.ac.at/~oemer/qcl.html">http://tph.tuwien.ac.at/~oemer/qcl.html</a><br /><br />
