"But name me something good and useful in ther world invented by one.

One that civilized humanity has benefitted from. One in let's say, the last 100-200 years."

Martin, I hesitate to get involved in the on-going dispute you guys have. However, I will.

The Muslim/Moslem/Arab contributions to world knowlede in mathematics, optics, medicine, science, astronomy, navigation--the list ain't endless but it is a long one. Next time ya use the deca system to do yer math, you can thank a long-dead Arabic scholar for the zero. In the past few hundred years, their contribution to 'knowledge' has not been great. However, before 1700, the North American contribution to world knowledge was nothing to write home about. My Scottish ancestors made tremendous contributions to humankind's data bank, but of late, no.

I think we have to remember Newton when he said, "If I have seen further, it's because I have stood on the shoulders of giants." So have we all. We are not the products of our own abilities, but rather we are the products of all our abilities, past and present.
