"All physical systems can be thought of as registering and processing information, and how one wishes to define computation will determine your view of what computation consists of."
"In order to figure out how to make atoms compute, you have to learn how to speak their language and to understand how they process information under normal circumstances."

More quotes by Seth Lloyd
"I have not proved that the universe is, in fact, a digital computer and that it's capable of performing universal computation, but it's plausible that it is."
"One of the things that I've been doing recently in my scientific research is to ask this question: Is the universe actually capable of performing things like digital computations?"
"Computers are famous for being able to do complicated things starting from simple programs."
"Nothing in life is certain except death, taxes, and the second law of thermodynamics."
"Instead of having to be a member of the Royal Society to do science, the way you had to be in England in the 17th, 18th, centuries today pretty much anybody who wants to do it can, and the information that they need to do it is there."
