An engineer is the obverse of a scientist.
Both use the same tools and techniques, so it is often thought they are similar; they are not. Those they share methods, they use them for opposite means.
A true scientist loves the unknown. The world is an endless delight of unknown forces waiting to be discovered. Exposure to the unknown brings expansion and scientists are there to catalogue it.
A true engineer hates the unkown. The world is an endless cacophony of unknown forces in need of control. The unkown is what gets people killed and engineers are there to master it.
Scientists are explorers of the natural world; engineers are colonizers.
