While Kenneth Ford’s 101 Quantum Questions was generally good, there was one really regrettable bit, in Question 23: What is a “state of motion?” When giving examples of states, Ford defines the ground state as the lowest-energy state of a nucleus, then notes that its energy is not zero. He then writes: An object brought… Continue reading The Real Point of Zero Point

Wind Power Economics and the Ability to Focus
Kevin Drum re-posts a chart on wind power made by Stuart Staniford showing that the number of new wind power plants installed in 2010 was way lower than in 2009 or 2008: This is meant as a starting point for discussion about the big economic issues that might’ve caused this. One of the many, many… Continue reading Wind Power Economics and the Ability to Focus
The Unexpected Leaping Ability of Bovines
I’m spending the day trying to get some work done on the book-in-progress, so I’m avoiding both work- and blog-related stuff. I don’t want to leave the site completely quiet, though, so here’s a question to ponder, relating to SteelyKid’s continuing fascination with Goodnight Moon: How does a cow jump over the moon? The father… Continue reading The Unexpected Leaping Ability of Bovines
Why Would Anybody in Their Right Mind Build the LHC?
In the comments following the silly accelerator poll, onymous wrote: [T]he point of the LHC isn’t to discover the Higgs. No one in their right minds would build a 14 TeV pp collider if their only goal was to discover the Higgs. While it’s true that the ultimate goal of the LHC is to discover… Continue reading Why Would Anybody in Their Right Mind Build the LHC?
I Am Baffled Regarding Chris Mooney
The kerfuffle of the moment in the science blogosphere once again relates to Chris Mooney, who is pretty much a kerfuffle looking for a place to happen at this point. This time around it centers around a Washington Post op-ed that is basically the executive summary of a American Academy of Arts and Sciences paper… Continue reading I Am Baffled Regarding Chris Mooney
Amazing Laser Application 9: Fusion!
What’s the application? The goal of laser ignition fusion experiments is to heat and compress a target to the point where the nuclei of the atoms making up the sample fuse together to form a new, heavier nucleus, releasing energy in the process. Nuclear fusion is, of course, what powers stars, and creating fusion in… Continue reading Amazing Laser Application 9: Fusion!
