Interactive plane geometry software

Interactive plane geometry software were made popular first by Geometer'sSketchpad at least back to 1994. It is a wonderful tool made possible bytechnology. Such program allows one to construct plane geometry drawingsdynamically, much in the way of Greek's 'Ruler and Compass'. For example,draw a triangle with lines bisecting the 3 angles. They intersect in apoint called the incenter of the triangle. (which is also the center ofthe largest possible circle inside.) Now, you can drag the corners of yourtriangle to change its shape, and all your drawings change accordingly.Because of such dynamic power, a few theories on plane geometry have beenfound because of such software.

In the 1990s, there's only Geometer's Sketchpad and Cabri Geometry.In late 1990 came Cinderella, written in Java. But since about post 2000,there's a explosion of interactive geometry software. As of 2007, thereare more than ten of them (counting only quality ones), many of them arefree. They are all similar. They are all of high quality. Almost all ofthem can be saved as Java appletes so that it can be placed on the webfor students to use without needing extra software. Their features differslightly. Several of them are FreeSoftware. The following is a short commentaryof the ones i've actually used (except otherwise stated).

Interactive plane geometry software

Interactive plane geometry software were made popular first by Geometer'sSketchpad at least back to 1994. It is a wonderful tool made possible bytechnology. Such program allows one to construct plane geometry drawingsdynamically, much in the way of Greek's 'Ruler and Compass'. For example,draw a triangle with lines bisecting the 3 angles. They intersect in apoint called the incenter of the triangle. (which is also the center ofthe largest possible circle inside.) Now, you can drag the corners of yourtriangle to change its shape, and all your drawings change accordingly.Because of such dynamic power, a few theories on plane geometry have beenfound because of such software.

In the 1990s, there's only Geometer's Sketchpad and Cabri Geometry.In late 1990 came Cinderella, written in Java. But since about post 2000,there's a explosion of interactive geometry software. As of 2007, thereare more than ten of them (counting only quality ones), many of them arefree. They are all similar. They are all of high quality. Almost all ofthem can be saved as Java appletes so that it can be placed on the webfor students to use without needing extra software. Their features differslightly. Several of them are FreeSoftware. The following is a short commentaryof the ones i've actually used (except otherwise stated).

★ Poly-Tile v.1.04 by S. T. Han. This puzzel is similar to a commercial program named Tesserae, published by In-Line designs Inc.In this puzzle, Tiles of different design are layed over a board. You remove them one at a time by jumping (flipping) adjacent tiles of the same design. The goal is to leave only one tile on the board. I find this game too difficult. It's also hard to analyze because the random initial placement and designs. Like Poly-Peg and Poly-Dol, you can customize your board when you got bored with the given configurations.

Sokoban

2005-10: Sokoban (倉庫番=warehouse keeper) is a classic game invented by Hiroyuki Imabayashi in 1982. It is a puzzle where the player pushes boxes around a maze to designated locations.

MYHOUSE

http://www.i-dac.com/game/myhouse/myhouse.html(2003-09,2009-02)

★ MYHOUSE is a clever and fun logic puzzle, by M Aono. It is a variation of the classic Sokoban. Your goal is to move a bunch of shrimps home. The shrimps move in sync. When one bump into wall, it doesn't move but the rest moves. The red blocks are fire and if one shrimps runs into it you die. Your goal is to align all shrimps in such way to move them home.

Klotski

Klotski is a classicsliding block puzzle. Your goal is to slide the red block all the way to theright side center. Yes, it can be done. This puzzle is dicussed in ScientificAmerican, March 1995 (Volume 272 Number 3 Pages 108-110), MathematicalRecreations by Ian Steward. A beautiful wooden set of this puzzle has beenmarketed by variouscompanies.

Loyd's Lunacy

Loyd's Lunacy is another block-sliding logic puzzle. The goal is to slide the large square from upper right corner to upper left. Author is Chip Moody. Written in 1990 but still works great under Mac OS X Classic in 2003. This program has a very funny 'About' dialogue.

Dirty Dozen

Dirty Dozen is a block-sliding logic puzzle. Writen by Nick Triantos in 1993 but still works under Mac OS X Classic in 2003.

by Viktor Massalogin.KriviznaPlus draws the Stereographic Projection from 3D to plane. KriDva draws the stereographic projection of S^3 sphere (x^2+y^2+z^2+z^2r^2) to the 3D space. These programs are extremelyfun and beautiful. I hope the author adds more explanations on themath. As of 2004, he added anotherversion CPace.

Koch Toy

http://www.efn.org/~jcburg/software.shtmlMac OS Classic (2003-10)

Koch Toy by Jim Burgess is another excellent simple program. It draws simple fractal curves like that of Koch snowflake. User drag points on a line and immediately see its effects after n iterations. The number of kinks can be adjusted by dragging the nodes. Clicking on a arrow button increase or decrease recursion depth.

Vectal

http://www.hot.ee/bntren/Program.html(2003-10)

Vectal draws simple fractal curves like that of Koch snowflake. User drag points on a line and immediately see its effects after n iterations. One feature of Vectal not in the mac Koch Toy is that user can change the sided-ness of the fractal on each line.

Fracture

Fracture, a fractal-generating screensaver, by Ben Haller.

Ben is also the author of the famous AfterDark screensaver module Satori, Rose, Lunatic Fringe. (Satori is the mesmeric color changing pattern. Rose is the dotted pattern of the math rose curve).

Dynamical Systems

StdMap

StdMap.Standard Maps displays the dynamics of several area preserving mappings. It will also find periodic orbits, cantori, and stable and unstable manifolds of any (symmetric) periodic orbit.

The program is written by mathematician J D Meiss.

1DMap

1DMap is another program by mathematician J D Meiss. It plots orbitmaps of various equations, including: logistic, cosine, cubic, exp, tangent,tent, circle. For each, one can plot the correspondig cobweb, bifurcationdiagram, and other statstical diagrams. The program is intuitive, but thereis no documentation or tutorial, so the reader must already be familiarwith the mathematics. Some textbooks on 1D dynamic systems are suggestedon his website.

Cycle Explorer

Cycle Explorer is a simple program that draws orbit maps of the equation f[x]:=x^2+c. Author is Jim Burgess.

ABC Map

ABC Map 'abc, iterate a 3D volume preserving system'. It plots orbit maps of what seems various 3D formulas of significance.I don't quite understand the math here. However, this program is wonderfulin that it is like a screensaver with mesmeric images. Dots appears ina 3D box, and these dots fluctuate seemingly ramdomly that forms very distinctpatterns. It's like watching statics on TV, but the statics form unpredicablepatterns constantly. One can rotate the box. It is a fantastic programeven if one knows nothing about the math. The equation it plots has thesenames: Froeshle, Arnold, ABC, Integrable, Adriana, and others. I hope theauthor writes a minimum amount of tutorial to benefit the masses.

IFS

IFS Another program by mathematician J DMeiss. This program does the Iterated Function Systems. It comes witha tutorial on IFS. Nice. After reading the one-page tutorial, Iunderstand that IFS is as follows: we have n mappings of theplane. For each iteration, one of them is chosen by a givenprobability function. So, we start with some points or line in aplane, then apply the functions in each iteration, and plot thetransformed points or line accumulatively.
