At Wikiversity I learn about:
using templates
" { {  learning1| using templates } } "

I'm adding coded text for the templates and links so I won;t need to always switch to "edit" mode. Ray Calvin Baker (talk) 20:57, 12 August 2012 (UTC)

I need a "play" area to test how to set up links, how to format (nicer-looking) pages, how to organize and plan my ideas and materials, etc.

Ray Calvin Baker 21:51, 27 November 2011 (UTC)

I expect there will be lots of experiments and lots of minor edits here.

Templates, pictures, and other items do not always appear where I think they should. Sometimes, I have to tinker with the page to make it look better.

You may play here too, please just post your fun activities at the bottom of this page, and sign (and date) your toys. If I like your stuff, we may wish to talk.

Files from commons[edit | edit source]

There are some beautiful animated pictures in Commons. Let me see if I can use one here.

[[8]] Racetrack from Conway's Game of Life Click on the blue link to see an amazing (but not quite technically exact) animated demonstration of "Machine Theory". I discovered several interesting other devices while "reverse engineering" the picture into a workable data file.

I need to post this with my contributions to the "Conway's Game of Life" 
talk page. It's a complex race track which exhibits several wonderful 
mechanisms of "Machine Theory".
I have sucessfully reverse engineered this picture; I am working on a 
data file which works with my QB64 BASIC implementation of a working 
program. This may become an example for more material on "Reverse 
Engineering" for the Wikiversity.

Never before have I seen:
(1) a contained shuttle (magenta), which sends gliders (yellow) around a 
(2) a linear "not" gate (green) -- no right angle turn here! 
(3) such a very compact "thin (by 2) gun" (green), 
(4) space ship eaters (blue), 
(5) glider (yellow) and space ship (red) collision, which sends out a glider 
(6) glider streams which convert a third incoming glider (yellow) 
    into a space ship (red) at a 45 degree angle, 

William Poundstone, in _The_Recursive_Universe_, documents:
(7) a space ship factory (grreen) pages 108 - 110 , 
(8) a pentadecathlon (magenta) reflecting a glider (yellow) pages 44, 45,
(9) The kick-back collision of two gliders (yellow) pages 198 - 200 and 
    other pagess, 
(10) the glider gun (green) pages 105 - 108, 
(11) the eater (blue) pages 38 -40, 

The color coding in the animation is very helpful -- but 
this is an animation, not a working program.

A signal propagates around this tortuous racetrack. Sometimes it is embodied 
as a Glider. Sometimes, it is embodied as a Spaceship. Sometimes, it is a gap 
in a regular stream of Gliders. 

The rows of blue or navy Blocks are merely decorative. They never interact 
with anything else during this simulation. 

1. Glider Gun "A" fires a Glider stream into Corner "B".
       Notice that there is a gap in the Glider stream at start-up time, 
       between Corner "B" and the "Linear NOT Gate", "C". 
       This gap is the racing signal.
       After the racing signal traverses the entire racetrack, 
       it removes one glider from the stream, leaving a gap to carry the signal. 
2. Corner "B" deflects The Glider stream into the "Linear NOT Gate", "C",
       which is really just a normal Glider Gun, 
       except incoming Gliders which approach just right 
       temporarily inhibit the formation of new Gliders. 
3. The "Linear NOT Gate", "C", converts the incoming gap into an outgoing Glider.
4. The Glider "bounces" off of Corner "D", and eventually encounters 
       a stream of Spaceships. 
5. A stream of Spaceships is created by the "Spaceship Factory", which is 
       composed of Glider Guns "E", "F", and "G". 
       I initialized the "Spaceship Factory" by including a temporary Block, 
       which removes a premature Glider, before it destroys one of the Glider Guns. 
6. The rightmost "Crab", "H", removes every other Spaceship from the stream. 
       (I call it a "crab", because I think it looks somewhat like a crab.
	You can call it a "Grab", because that's what it does, or 
        you can call it a "Spaceship Eater", because that's what it is.) 
       This leaves a gap in the Spaceship stream, through which the Glider 
       returning from the Pentadecathlon "E" can safely pass.
6. One Spaceship and the incoming Glider collide and are destroyed, but a new Glider, 
       heading toward Pentadecathlon "E", is formed from the debris of the collision. 
7. When the incoming Glider collides with the Pentadecathlon, "E", it is destroyed, 
       but a new outgoing Glider, heading in the opposite direction, is formed 
       from the collision debris. The Pentadecaqthlon "E" continues its oscillation 
8. All of the surviving Spaceships in the stream are destroyed by Crab "I".

Notice the similarities between the streams of Gliders (two streams are parallel, 
but moving in opposite directions) produced by the "Spaceship Factory", 
Guns "E", "F", and "G", and the streams of produced by Gun "K" and Compact Thin Glider Guns  
"M" and "N". These Glider streams (parallel, but moving in opposite directions) interact 
with the incoming racing Glider to form a nes Spaceship.

9. Glider Gun "K" fires a stream of Gliders into Eater "L".
10. Two Glider Guns, "M" and "N", comprise a "Compact Thin Gun". 
       If you number the Gliders in the streams from "M" and "N" properly, 
       you can see that "odd" numbered Gliders collide to form a temporary Eater. 
       The next even numbered Glider from Gun "N" destroys itself and the temporary Eater, 
       which allows the even numbered Glider from Gun "M" to escape in the 
       thinned Glider stream.
       A temporary Eater precursor and three Gliders are required to start the 
       "Compact Thin Gun" so that it emits a Glider stream with the correct phase.
       An incoming glider (the racing signal) then may interact with a Glider 
       from the "Compact Thin Gun" stream and the Glider stream passing between 
       Gun "K" and Eater "L", to form a new Spaceship. 
11. Gliders not consumed by the formation of a nes Spaceship are destroyed by Eater "O", 
       which regenerates itself. 
12. Glider Guns "P" and "Q" comprise a slightly different form of "Compact Thin Gun". 
       Temporary Blocks are formed by collisions of Gliders from each Glider stream. 
       Then a Glider from Gun "Q" removes the Block, just in time to allow a 
       Glider from Gun "P" to pass through. Gaps in the resulting "thinned" stream 
       are required, to allow the racing signal to pass through, after it is reflected 
       by the "kickback reaction" with a Glider from Gun "S". 
13. Eater "R" removes excess Gliders from the "Compact Thin Gun", "P" and "Q".
14. Glider Gun "S" fires a stream of Gliders into Eater "T". 
       When the racing signal Glider encounters this stream, two Gliders 
       are destroyed, but a new Glider, heading for Corner "U" is formed 
       from the collision debris.
15. The new racing signal Glider passes through a gap in the thinned stream, 
       and "bounces" off Corner "U".
16. The "bounced" racing signal Glider meeets the Glider stream from Gun "A" 
       in the vanish reaction, leaving a gap in the stream to carry the signal.

The cycle repeats indefinitely (forever). This entire configuration becomes 
a very long period oscillator, after the stream of Spaceships is completed. 
I took some liberties, to reduce the cell count, in starting the "Spaceship
