We seem gradually to be groping toward an understanding of the world of subatomic particles, but we really do not know how far we have yet to go in this task.

The philosophical question before us is, when we make an observation of our track in the past, does the result of our observation become real in the same sense that the final state would be defined if an outside observer were to make the observation?

If we have an atom that is in an excited state and so is going to emit a photon, we cannot say when it will emit the photon. It has a certain amplitude to emit the photon at any time, and we can predict only a probability for emission; we cannot predict the future exactly.

In talking about the impact of ideas in one field on ideas in another field, one is always apt to make a fool of oneself.

As we put autonomous cars on the road, connect Alexas to our lights and our thermostats, put ill-protected Internet-connected video cameras on our houses, and conduct our financial lives over our cell phones, our vulnerabilities expand exponentially.

The nature of the Internet and the importance of net neutrality is that innovation can come from everyone.

It seems like the web, particularly software as a service, provides ample opportunities for you to flourish economically, completely aligned with the broader open source community.

The world is so heavily influenced by technology, and it has started to feel like it's not on solid ground. The world has become unreliable, unknowable. Facts are vulnerable, and things you have come to rely on are no longer there.
