> Engineers design and build things on top of the discoveries of scientists I agree with a lot in this post, but I think it's also worth mentioning how this is a two-way street. Practical considerations often drive theory research as much as the other way around.
There's a chance that it didn't actually happen that way, though.
edit: I also heard that Louis Pasteur did work for breweries, answering the question "Why do some batches come out nasty while most are fine, given the same inputs?"
