Technology and Science: Do they really compare?

In the Heidegger article we read for today titled, “The Question Concerning Technology”, he talks about technology and science. On page 14 he says, “It is said that modern technology is something incomparably different from all earlier technologies because it is based on modern physics as an exact science.” As Katie discussed in her post, somehow this man-made concept of computers has turned into a ‘science’. Do we put so much trust into this technology that we are willing to call it a science? That is something that is a known fact and always true? Heidegger discusses how technology and a tree can be comparable. He says that ‘technology is not the equivalent to the essence of technology” and compares this to a tree by saying that while a leaf or a branch may be a part of a tree, they do not represent the whole tree itself. Here, he is comparing something as technologically advanced and man-made to something so natural and scientific like a tree.
Another reference to science is used when Heideger says “Surely technology got under way only when it could be supported by exact physical science.” This is very true. Computers and technology became so significant and prevailing in our lives that we decided to start a whole new field of study and work titled ‘Computer Science”. The use of the word ‘science’ assumes that it is essential to our being. It says that computers are comprised of fact and detail.
When I took a computer science class here at DU, we were taught fundamental concepts on how to create web pages. If you type in ‘

’ a space would appear. If you typed in ‘

’ the words would be centered on the page. Like science, if I did one thing, a specific reaction would occur. I always knew what to expect. As long as I was taught exactly what to type and exactly what buttons to press, the specific reaction I was looking for would occur.
Now just because there is a cause and effect, an input and an output like in science, does this really mean that we can truly compare this man-made field of technology to something as natural as science?
