Computing is deep!
If you tell people you work in IT, they won't likely associate you with the great and profound sciences that attempt to explain our reality. But in fact, computer science, including information theory, may underpin the deepest fields of science and mathematics itself.
Lord Kelvin said if you know something exists, but don't know how to measure it, then:
your knowledge is of a meagre and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely... advanced to the stage of Science.
But you can't measure anything (thus define it) until you've built a series of steps (an algorithm) for measuring that thing.
So science, like computing, is built on algorithms.
