[B]Dear Dr Wesam
Very many thanks for your answer, it is honer me that you advise me related to the concepts of GIS .Actually, I find your opinions very important to any body who wants to know more about GIS.Firstly, I respect all arabian researchers who work independtly in thinking aboutt our bad scientific position in the world and I know that there are many Arabian Scientiists who are very cleaver in their majors and fileds.what about you as a example of how to thiink globaly whien you act and work regionallly, I mean you are work and think like a westren person and I know more people like you in our Arabian world.

I meant another meaning by GIscience but may it was not clear to you. I want to say that GIscience is some things differnet from GIS as you know and that what have learnt in the first lecture in the module of principles of GIS. There have been two terms GIS and GIscienc. Let us show you the main definatrion which has given to us in the lecture : Giscience is (the science behind the technology and examines fundamental questions raised by the use of GI systems and technology. Moreover, it is the science needed to keep the technology at the cutting-edge). Hopefully, that the idea is clear and I could explaine the main meaning. In my opinion the number of books related to to GIscience are more than GIS softwares books and you have a good experience in this field more than me. Another issue dear it is the the scientific thinking
when I read some in a book which is titled ( Thinking About GIS) for Roger Tomlinson who has known as the father of GIS I stoped more in his saying {{ A real world GIS is actually a complex system of interrelated parts, and at the centre of this system is a smart person who knows and understands the whole}}. Yes Dear it is the whole Knowledge it does not matter to be exper in every thing in GIS but it is mportant to know how to think in GIS correctly.In our university there is three kinds of GIS masters one related to Human Geography (GIS Hons) Physical and the third is GIS bure. what does this means ? it means GIS as a tool support Human and physical Geography but as a science it will be in another meaning the evedence about that the contents which are studied it different in GIS master bure from the other.

I have never supported GIS more than other sciense but I try to explaine what I have learnt here and Iam still sutraggling with the new system and approaches. Before coming to UK I read scientific thinking for Zaky Nageeb Mahammoud and I have knew that critical thinking in our Arabian world would be difficult to generate.

I hope to find time totranslate more to all brothers and sisters in our gisclub and I promise that I work hard to learn what I could to be useful for our countries.
