dedicated to youth (former Club Jeunesse du Crédit Communal de Belgique).
was in close contact with Akira Fujii, author of this fine picture of comet
Bennett, in the late 70's and 80's.
began in 1978, when I published advertisings and various high
resolution pictures of the moon and the sun in specialized magazines to invite
the amateur community to participe in activities of Club Observatoire ORION,
a non-profit association that I founded with a friend in 1975, during our studies at
St.Paul College (B).
a little more experience, I wrote technical articles and continued
to publish pictures in amateur magazines like Ciel et
Terre (B), Cosmos (B), Ciel et
Espace (F), ScienceAm (F), Man and Stars (JA), Sky &
Telescope (USA), including in books like "A l'affût des
étoiles" (F), sometimes in cooperation with other amateurs from
Belgium, France, Switzerland, Germany, the U.S.A. or Japan.
is at this occasion that I introduced Akira Fujii, the famous japanese
astrophotographer to the French community in publishing some of his images
M42, etc) in Ciel et Espace.
He was very honored to be appreciated by the French community after have been
congratulated in his country and in the U.S.A. for all his astrophotography work.
Receiving no financial support from the school authorities, in 1979,
I moved my club to Brussels City, where I decided to work in collaboration with a local
I published an half page article in the largest
Brussels newspaper "LE SOIR" about my objectives. Reply
from the amateur community was immediate. Young and adults soon joined the
Thanks to my
pictures (mainly those of the moon in high resolution), I personally won
several contests, mainly in the U.S.A. and Japan. I received for gift a
small refractor of 60 mm f/5 and a large electric barn
door on a tripod. Superb gifts for a young adult short of money !

Article about home
computing published in a well-known newspaper distributed in Namur (B).
the meantime, I bought my first Apple computer soon equipped with 1 MB of
RAM (it was much at that time !), a graphic board and an enhanced
keyboard. At that time such a computer cost about 4000 € !, much money
invested in a hobby. Hopefully 20 years later a high-end computer is worth
half that price. Thanks, Moore !
digital images and computing, I used my spare time to write technical articles,
creating graphics and programs that were, to my surprise, published in newspapers
like Confluent (B), and computing magazines like
Nibble, SoftDisk (USA), L'Ordinateur Individuel
(F) and other well-known publications edited in Belgium, France, Japan and in the U.S.A.
the special issue of Summer 1986 I published in L'Ordinateur
Individuel (F) dedicated to home computing, my first in depth article dealing with the use of videodisks together with home
computers, a way to support this new media, ancestor of the DVD.
My objective was
to learn to the French readers the existence of this technology, and demonstrate them all the
potential of this marvellous media, mainly in the field of education.
In the meantime, I
became member of the "Optical Memory User Group" (OMUG) and the
"Amateur Space Telescope" association from Troy University, two
american non-profit organizations devoted to the use and
development of new technologies for amateurs. These projects were cancelled
after some years by lack of support from professionnals.

of the many technical articles published in Cosmos magazine (B) in the 1980's.
In the end of 80's, I had
gathered a large collection of astronomy pictures and technical documents
that used a dozen of binders.
To not loosing all this material,
I decided to publish these information in
a book dedicated to amateur astronomy including a large part dealing with astrophotography.
Pierre Bourge and other well-known French writers as well as manufacturers
like Interoptic, Celestron and Meade gave me a positive feedback. I seeked for
some months a French editor willing to publish my project, in vain.
chance in 1987 I contacted Bordas-Elsevier editor to know
if he could be interested in publishing this book. For various reasons,
the editor prefered to give me the opportunity to participate in the scientific
supervision of Ian Ridpath's book dealing with
astronomy. I was very proud and excited : think about, my very first collaboration with an editor at
27, and very well remunerated ! For the first time my name was displayed in a
supervision of Ian Ridpath's popularizing book in 1987.
Cyprae leucodon, one of the most beautiful cowries of my collection.
am interested in seashells since I am kid, and surely after reading an issue
of National Geographic magazine about the subject. Later, I got the opportunity to buy
some marvellous specimens, specially coming from old collections.
my most beautiful seashells are displayed in Kenneth Wye' s book herewith,
all gem specimens of well-known families that are Conidae, Cypraeidae, Muricidae,
Pleurotomariidae, Strombidae among others, pure natural beauties, but that I partly sold since that
diver and very concerned by the preservation of our natural resources, I only buy
specimens from old collection, and I never order seashells to divers, thus new
specimens (all the less than they become smaller with overfishing). It is my way to
protect life, these organisms being better living in nature than dead in my
living room !
dozen of my seashells specimens are displayed in K.Wye's book.

2000, after have used BBS and other Compuserve for years, I decided to create
a website based on my projects of books that remained in my drawers. I decided
to publish on Internet all the documentation that I gathered throughout these
years, the educational material, texts, thousands of pictures
and gigabytes of animations and sound recordings.
This huge collection
representing close to 4 GB of information constitutes the
project that has materialized by this web site.
more than 660 articles and 14000 images among others, this site receives about 280 visitors each day.
It is in July 2009 that it exceeded 1 million unique visitors.

my activity is mostly oriented to the sharing of all my knowledges and
documents with the public at both non-profit and commercial purposes.
As listed in my awards and commendations page, regularly editors, authors,
teachers, associations, webmasters and many amateurs ask me permission to
publish some of my images or articles, that they are written in French or
in English, on a website, in a magazine, a book or in an educative CD-ROM. This is always with pleasure that I share these documents
while asking you to respect the copyright.
too, associations or editors contact me to write an article in their magazine,
about sciences or technology.
this context, in 2004 my history of amateur
radio referenced on the ARRL
website has been used by Ian Grinter and Kevin Crockett, VK3CKC, to write
the academic cursus on Technological
pathway to the modern HF transceiver in the frame of the australian
Advanced Diploma of Electronics. This story was also used by Ron Bertrand, VK2DQ,
in the frame of his "Education hour" about ham radio at Radio
& Electronics School, Qld, Australia as well as by the SADARC
Radio Club, VK3SOL, in Vict., Australia.
parallel I continue writing articles in paper and electronic magazines like CQ
Astrobiology Magazine to name a few.
time permits I also publish astronomy, weather or nature pictures in online magazines
or photo libraries (see below).

some years, I have created renderings,
artworks and other images
to illustrate various subjects developed on this website, mainly concepts,
landscapes, exoplanets and peculiar celestial objects. You will find some of the finest images
on the website of several institutions, astronomers, and in magazines
Sciences et Avenir,

also read my first
book about quantum physics, the result of more than ten years of investigations. It is published in
French to begin, to Aegeus
Editions, and is entitled "Un siècle
de Physique : 1 - La Physique Quantique".
To complete articles published on this site or in magazines,
in 2007 I have opened a blog written in French entitled "Bouillons
de Cultures". It is a way for me to share easier and faster ideas and opinions with you.
Advantage, hosted by Blogger (belonging to Google), new articles are immediately indexed
and available in the first page of Google in the next minutes. This
blog receives about 100 visitors daily. Added to
the website, they are about 400 visitors who read daily my articles.
so ends temporary almost half a century of a simple life, essentially
dedicated to sciences and my hobbies. I hope that my knowledges will benefit to most of you, that
and my blog will grow with time, and in spite of my modest resources, will
provide you useful information about sciences, technologies and
philosophy, and even a bit more.
