	11:45AM -> NSF
		
Admin
	Duc's Women in Science description
		-> Web page as well, serve as summary

	Please continue updating; I'll install from D.C.

PROJECTS

3D Printing & Geometric Models
==============================
	Print run today
		Then depowdering [Diana, Gillian, Samri]
	Knitting needles + joints: design in progress [Diana]
	daVinci models [Gillian]
	Kepler punch bowl: start design [Gillian, Diana]

D-Forms
=======
	Ribbon curves question: progress, but not solved
	Candidate ribbon can be constructed from binormals, 
		but unclear if truly is a ribbon
	Investigating the First Fundamental Form [Stephanie, Duc]

Pop-Up Books
============
	POV-ray animation of medial plane rotation: working!
		Fit function to angle relationship [attached]
		Aesthetic improvement [Nell, Ana, Faith]
	... => MPEG?  [Nell]
	Medial card model; photo, description, questions, etc. [Faith, Ana]
	Rotary animation: 
		1. V-fold in valley crease of parallel fold
		2. V-fold in mountain crease of parallel fold
	#2 easier to grasp.
	Goal: Mma animation
		Angular relationships nonlinear
		Fix on model
		Make empirical plot of angular relationship 
			(for later checking against Mma)
	Subgoal: Animate just V-fold in mountain crease [Ana, Faith, Nell;
			Mma consultation with Duc, Stephanie]

		b----p----a
		 \   |   /
		  \  |  /
		   \ | /
		    \|/
	             v

	1. Compute positions of v,a,b in 3-space.  Check in Mma.
	2. p is equidistant from all three:
		Clear[x,y,z]; p = {x,y,z};
		Solve[{
		(p-v).(p-v) == (p-a).(p-a)
		(p-v).(p-v) == (p-b).(p-b)
		(p-a).(p-a) == (p-b).(p-b)
		}, {x,y,z}]
		???
	
		
Protein Folding
===============
	Paint sphere model in traditional colors?  [Samri]

Interlocked Chains
==================
	Locked 11-chain + 2-chain painting [Samri]
	Separate 3/4-tangle: build & paint [Samri]
	K'nex-like mechanism at angles between 60-90, 
		say, 75 deg? [Samri, Diana]
		Consult John K.?
	John's improved universal joint?
