In science, we use a lot of words that were borrowed from Latin and Classical Greek. It is an interesting mental exercise, to imagine yourself trying to explain notions of modern science and artifacts of modern life to a person from, say, 2,500 years ago, whose native language was Latin or Greek. Not only would it be difficult to transfer our jargon - because the the original meaning of the word might have been different (why is 'atom' divisible? or, why is amber a basic constituent of matter?), many things we are so used to would make little sense (what is it that you are computing all the time?).
