quantum mechanics
Are there parallel universes? Universes in which, rather than reading this article, you are still asleep; in which you are happier, unhappier, richer, poorer, or even dead? The answer is "possibly". It's a controversial claim but one that has won more and more followers over the last few decades.
This podcast featuring Paul Davies, a theoretical physicist and cosmologist at Arizona State University and Director of BEYOND: Centre for Fundamental Concepts in Science, explores this difficult question and accompanies our What is time article.
PhD student Demian Goos talks to us about his work on qunatum mechanics.
The "quantum mechanic" talks about how quantum computers might impact society and the limits of measurement.
Most of us know what we mean when we say that something has happened. For theoretical physicists, however, this isn't an easy question. Sean Carroll of the California Institute of Technology explains why it's hard to define events and what to do about it.
Most of us know what we mean when we say that something has happened. Theoretical physicists, however, struggle with the concept of an event. Why?
Quantum mechanics seems to suggest that passive observation is impossible: the very act of looking at something can change what's being looked at. In this video interview, we talk to David Wallace and Adrian Kent to find out more.
Imagine your weight depended on the colour of your underwear! Something quite similar happens with measurements in quantum physics. Find out more here...
