The Ultimate Test of Atom and Neutron Neutrality

Aussie Laser-Pointer Ban in New South Wales.
No mention if there is a power threshold. (see update, below)
Legitimate users, like astronomy enthusiasts, will have to apply for prohibited weapons permits.
That’s right, mate. You’ll need a frikkin’ carry permit for your laser pointer (especially if it’s mounted on the head of an endangered [...]

An interesting paper was brought to my attention recently, on a new technology for ion beams based on magneto-optic trapping. My only experience with ion beams was with the transport of radioactive ions at TRIUMF (it’s far easier to shuttle your particles around macroscopic distances as ions), but ions beams are also used for [...]

Evidence of gravitational radiation from a binary black hole system
A central black hole, with a mass equal to 18 billion times that of the Sun, is orbited by a smaller one, and the interaction of the system with its surroundings produces brightness changes that allow astronomers to study the evolution of the orbit.
And the system [...]

I agree that finding that half of polled students can’t identify that “human beings, as we know them today, developed from earlier species of animals” is true doesn’t imply that the other half are creationists, given that other science questions also garnered less-than-spectacular results.
However, it also doesn’t mean that all of the [...]

Gordon Watts has become The Margin Lady (and that’s a sequel to the original margin lady story).
One of the things I’m responsible? Make sure the figures are done right. Make sure everyone uses the same units. Make sure everyone is printing on A4 paper. Make sure the margins are right!
I am the margin lady! Shoot [...]

I went out geocaching in the wonderful weather today. First stop was to check on caches I have placed, in response to a couple of emails from people who couldn’t find them. Sure enough, they had been muggled. One cache almost completely gone — only the lid and the logbook could be [...]

An online colleague at my blog-host, SFN, makes the following observation:
Wouldn’t it be amusing if science groups started leading tours of the Creation Museum, lead by archeologists pointing out the flaws in their reasoning and why evolution really does answer those questions?
It would be a great response to that story out of Colorado about creationists [...]
