David Elieser Deutsch FRS is an Israeli-born British physicist at the University of Oxford. He is a Visiting Professor in the Department of Atomic and Laser Physics at the Centre for Quantum Computation (CQC) in the Clarendon Laboratory of the University of Oxford. He pioneered the field of quantum computation by formulating a description for a quantum Turing machine, as well as specifying an algorithm designed to run on a quantum computer. He is a proponent of the many-worlds interpretation of quantum mechanics.

Every problem that is interesting is also soluble Science, Mathematics, Engineering & Technology
To say that prediction is the purpose of a scientific theory is to confuse means with ends. It is like saying that the purpose of a spaceship is to burn fuel. ... Passing experimental tests is only one of many things a theory has to do to achieve the real purpose of science, which is to explain the world. Science, Mathematics, Engineering & Technology
Every problem that is interesting is also soluble.
Humans may or may not have cosmic significance, and if they do, it will be by hitching a ride on the objective centrality of knowledge in the cosmic scheme of things. Education, Learning, Knowledge & Training
I don't think it would be a good idea for scientists to have more political power. Scientists as a group are more inclined to try to derive an ought from an is, than the population at large. Power
I myself believe that there will one day be time travel because when we find that something isn't forbidden by the over-arching laws of physics we usually eventually find a technological way of doing it. Time ;Travel
Is the human race a universal constructor?
It is possible to build a virtual-reality generator whose repertoire includes every possible environment.
Our best theories are not only truer than common sense, they make more sense than common sense.
Quantum computation is... a distinctively new way of harnessing nature... It will be the first technology that allows useful tasks to be performed in collaboration between parallel universes. Nature ;Science, Mathematics, Engineering & Technology
Science is objective. And in my view we cannot take any experimental results seriously except in the light of good explanations of them. Science, Mathematics, Engineering & Technology
The brain is the only kind of object capable of understanding that the cosmos is even there, or why there are infinitely many prime numbers, or that apples fall because of the curvature of space-time, or that obeying its own inborn instincts can be morally wrong, or that it itself exists.
The most important application of quantum computing in the future is likely to be a computer simulation of quantum systems, because that's an application where we know for sure that quantum systems in general cannot be efficiently simulated on a classical computer. Future
The overwhelming majority of theories are rejected because they contain bad explanations, not because they fail experimental tests.
The truly privileged theories are not the ones referring to any particular scale of size or complexity, nor the ones situated at any particular level of the predictive hierarchy, but the ones that contain the deepest explanations.
Time travel may be achieved one day, or it may not. But if it is, it should not require any fundamental change in world-view, at least for those who broadly share the world view I am presenting in this book. Time ;Travel
To me quantum computation is a new and deeper and better way to understand the laws of physics, and hence understanding physical reality as a whole.
Where we have good, testable explanations, they then have to be tested, and we drop the ones that fail the tests.
