The word uncertainty is used a lot in quantum mechanics. One school of thought is that this means there’s something out there in the world that we are uncertain about. But most physicists believe ...

The famous double slit experiment shows that particles can travel on two paths at the same time -- but only by looking at a lot of particles and analysing the results statistically. Now a ...

Quantum particles are not really just particles…they are also waves. The word uncertainty is used a lot in quantum mechanics. One school of thought is that this means there's something out there in ...

Several weeks ago I picked up “The Elegant Universe” because I thought it would have information on The Ultimate Theory. Soon afterwards, I picked up “How to Teach Physics To Your Dog” in order to get ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Quantum mechanics is one of the most ...

The double-slit connection In their paper, the authors draw an elegant analogy to the famous double-slit experiment, where particles like electrons produce interference patterns when passed through ...

If quantum weirdness is all in the mind, what about optical interference? Set up apparatus that can record the arrival of an individual photon on a screen after passing through one of two slits, and ...

I think what I read was saying that in quantum mechanics, when more than two possibilities are present, the other possibilities are ignored by the particles. And that in terms of the experiment, when ...
