Appearance is one thing, but reality is another. The world does not appear to be a hologram, but maybe it is. Thus begins physicist Leonard Susskind in opening a doorway between science and religion ...

The measurement problem in quantum mechanics looks at how an experimental outcome changes, simply by observing it.

How can the strange properties of quantum particles be exploited to perform extremely accurate measurements? This question is at the heart of the research field of quantum metrology. One example is ...

In the everyday world that humans experience, objects behave in a predictable way, explained by classical physics. One of the important aspects of classical physics is that nothing, not even ...
