Subject: What fun!

I was really impressed by the announcement for the International
Workshop on Parallel Problem Solving from Nature (PPSN).
I was especially intrigued by the "Ladies Programme" given
near the end of the announcement, including a Westphalia Park
walk, and a visit to a "museum of cookery-books".  Gee, we
ladies sure have it good at these conferences, getting to 
do all kinds of fun things, while the men have to sit inside
listening to all those boring and manly scientific talks.

Subject: Book announcement: "The Algorithmic Beauty of Plants"

  Here is an announcement from Springer-Verlag for Lindenmayer and 
  Prusinkiewicz's new book: "The Algorithmic Beauty of Plants". The
  announcement includes the table of contents and ordering information.
  
  After the review, I have included a brief blurb that Springer-Verlag
  asked me to write for press releases for the book. I apologize for
  the somewhat "flowery" language (if you'll pardon the pun), but that's
  the kind of promotional language they like to put in press releases.
  As far as I can tell, they didn't use it!
  
  The promotional language aside, this is a great book! It is stock full
  of L-system "genotypes" for the generation of a great variety of botanical
  structures and developmental patterns. Anybody interested in studying
  plant structure, growth and development, embryology, the genotype/phenotype
  relation, 2D tissue growth, or even 3D embryo development should definitely
  run right out and devour this book. 
  
  The book is a great testament to the life and work of Aristid Lindenmayer,
  who died last October. Prusinkiewicz and his collaborators at the University
  of Regina deserve a healthy round of applause for the care and dedication
  that went into its production.
  
  I believe that Prusinkiewicz's Virtual Laboratory software, which was
  used to produce the beautiful images in the book, is available for purchase
  as well. I will find out the procedure for obtaining the software
  and post the information here. 
  
Cheers!

-----------------(Springer-Verlag annoucement follows)----------------------

Springer-Verlag is proud to announce an important new book:

               "The Algorithmic Beauty of Plants"
         
                               by 
                    
                    Przemyslaw Prusinkiewicz
                              and 
                       Aristid Lindenmayer
                       
     
This book is the first comprehensive volume on the computer simulation of plant
development. It contains a full account of the algorithms used to model plant
shapes and developmental processes, Lindenmayer-systems in particular. With
nearly 50 color plates, the spectacular results of the modeling are vividly
shown.

The volume is the result of an interdisciplinary research effort. We believe
that it will be of interest to professionals working in the areas of
(theoretical) biology and botany, molecular and cell biology, mathematics,
computer science, computer graphics/animation, and the rapidly emerging field
of artificial life. The implications of the work will also be worthwhile to
laypersons intrigued by the aforementioned disciplines. 

>From the Table of Contents:

	1. Graphical modeling using L-systems
	2. Modeling of trees
	3. Developmental models of herbaceous plants
	4. Phyllotaxis
	5. Models of plant organs
	6. Animation of plant development	
	7. Modeling of cellular layers
	8. Fractal properties of plants		
	
	Appendix: Software environment. 
	          Virtual laboratory and list of laboratory programs

--------------( Chris Langton's flowery review follows )----------------- 

               I think that I shall never see
               a poem lovely as a tree.

               Poems are made by fools like me
               But only God can make a tree.



------------------------------
 
From: ``Trees''!the

There is a beautiful irony here, when we place Kilmer's evocative poetry
in the context of our current understanding of the nature of trees.
For we now know that it is DNA which makes a tree, and that DNA is  
the material substrate in which the genetic code is expressed. 

The genetic code is the language in which the poems of nature are written, 
and it is these poems, penned in the ink of nucleic acids and cast in 
intertwining doublets, that give rise to trees and flowers, and men and women.  

Thus, syntax and semantics, grammar and interpretation, lie at the heart
of both poems and trees. Each is an elegant semantic structure, they 
are merely cast in different media.

In this book, Aristid Lindenmayer and Przemyslaw Prusinkiewcz lay bare
the essential beauty of the poetry of nature. Here, the poetry is cast in 
yet another language, the language of L-systems. In these pages trees, flowers, 
meadows and forests spring to life from short, formal poems, written in a
terse verse. The wide variety of botanical structures, and the complex cycle 
of their development from seed to bloom to seed again, are revealed fully
and with careful attention to anatomical detail. 

Readers of this book will come to a deep appreciation for the manner in
which simple genotypes bloom into complex phenotypes. The authors clearly 
elucidate the power of recursive description, and the extent to which it 
is employed in the genetic poetry of nature. 

This book is at once a scientific text, a book of poems, and a work of art. 
The combination illustrates beautifully how language and information, pattern 
and structure, can come to have a life of their own, in whatever medium they
are expressed, whether it be in the medium of carbon-chain chemistry or 
in the medium of silicon circuitry.
