Hawking radiation in the lab

A highlight of the recent NZ Institute of Physics conference was the Dan Walls medal talk given by Matt Visser. Matt has been working on general relativity. That's not desparately unusual for a physicist, but Matt has been successful in working on some of the crazier aspects of relativity and getting it published – wormholes, […]

I was driving back through one of those heavy showers that have been marauding around the place recently, with windscreen wipers full pelt on a rather wet road. However, these showers don’t last for very long, and […]

Was that a Higgs I just saw?

Well, CERN was certainly twittering away last night, though, to be fair, I’m glad I didn’t stay up for the press conference. Some things are worth trading in your sleep for, such as an eclipse of the moon (occasionally) or other astronomical event, an Ashes test, a Royal Wedding (just about), but, I’m afraid, not […]

The varied world of physics

It was a very interesting day at the NZ Institute of Physics conference. I learned about some of the physics experiments done at the South Pole, how to trap, observe and count atoms (and that high school physics teachers who tell their students that you can’t see atoms need to update their knowledge), some results […]

Momentum conservation

It’s mid-semester break here at Waikato so I have time to breathe and get back to things other than teaching, such as seeing what the PhD students are up to. Yay. But, here’s a comment about what I was talking about last week with the first year students: conservation of momentum. If you look in […]
