I've recently been organizing my physics/science links, so I thought I might share some of these here. This list might get updated. Any suggestions?

It's been a while since my last blog post, so I think it's time to share some things.

A new particle
First of all, I have to mention the discovery of a new particle last year. Last March I mentioned there had been signs of a particle in the region 124-126 GeV. The discovery of a new particle, a boson, was announced in July last year (press conference). The properties...

A couple of months ago I did a number of double-slit experiments at home. I've noticed there are quite a few people who are interested in trying this experiment, so I decided to write a short guide on how to do it. Here it is.

QUESTIONS & ANSWERS

What is the double-slit experiment?...
