Abstract
Information and computation are two concepts that are being applied every day more and more in science. However, these concepts are sometimes misunderstood about what they imply by several physicists and several computer scientists. Information and computation are not mathematical concepts as computer scientists usually think and also they are deeper physical concepts than what physicists usually assume. For this reason, this essay is dedicated to explain why information and computation are physical concepts and why they are deeper concepts. Until now, computation and information are concepts derived in the epistemic scheme of energy but they could be taken as fundamental concepts allowing us to understand nature from a new perspective.
