Phillip Ball has a long aggrieved essay about the Many-Worlds Interpretation, which is, as Sean Carroll notes, pretty bad. Ball declares that Many-Worlds is “incoherent, both philosophically and logically,” but in fact, he’s got this exactly backwards: Many-Worlds is, in fact, a marvel of logical and philosophical coherence, while Ball’s objections are incoherent and illogical.… Continue reading The Philosophical Incoherence of “Too Many Worlds”

Social Media Are Social
I didn’t see this before yesterday’s post about Twitter, but over at SciLogs, Kirk Englehardt gets evangelical, offering a very chipper list of “Ten Reasons for Academic Researchers to Use Social Media.” I’ll just put the item headers here, though each of these has a more complete description, with links to lots of other stuff:… Continue reading Social Media Are Social
Twitter Is Kind of Useless
The AAAS annual meeting was last week, which apparently included some sessions on social media use. This, of course, led to the usual flurry of twittering about the awesomeness of Twitter, and how people who don’t use Twitter are missing out. I was busy with other stuff, so I mostly let it pass, and of… Continue reading Twitter Is Kind of Useless
Real-World Physics and Objectively Pro-Injustice “News”
Over at Quantum Progress there was a recent series of guest posts about a social-justice-in-physics curriculum used by high school teacher Moses Rifkin. I sort of glanced at it, said “Huh, that’s sort of interesting,” and moved on, but this got picked up by some right-wing sites, and exploded. To the point where the awful… Continue reading Real-World Physics and Objectively Pro-Injustice “News”
Problems with the Pipeline
Via Curt Rice (or, more precisely, somebody on Twitter who posted a link to that, but I didn’t note who) there’s a new study in Frontiers in Psychology of the STEM “pipeline”, looking at the history of gender disparities in STEM degrees. You can spin this one of two ways, the optimistic one being “Women… Continue reading Problems with the Pipeline
Winter Thermodynamics: Foggy Glasses
We’re having a brutal cold snap at the moment, and while today’s early-morning dog walk was considerably warmer than yesterday’s, it was still 0F/-18C out, which is way colder than I like. When I came back in the house after the walk, my glasses instantly fogged up. But I had to take some stuff outside… Continue reading Winter Thermodynamics: Foggy Glasses
How Fast Is SteelyKid’s Nerf Gun?
SteelyKid is spending a couple of days this week at “Nerf Camp” at the school where she does taekwondo. This basically consists of a bunch of hyped-up kids in a big room doing martial activities– taekwondo class, board breaking, and “Nerf war” where they build an obstacle course and then shoot each other with dart… Continue reading How Fast Is SteelyKid’s Nerf Gun?
Top Blogging of 2010, Then and Now
The final bit of meta-blogging I’ll do this weekend is another look at what survives from past years. Unfortunately, when National Geographic took over, they broke our Google Analytics access, so I can’t see blog stats from before mid-2012 any more. I do, however, have this old post listing the top posts of 2010, traffic-wise,… Continue reading Top Blogging of 2010, Then and Now
What Survives from 2013’s Blogging?
Continuing the weekend theme of meta-blogging, one of the questions I’ve occasionally wondered about in doing top-posts lists for a given year is the problem of a bias against recency– that is, that posts put up toward the end of the year are inherently at a disadvantage because they’ve had less time to integrate up… Continue reading What Survives from 2013’s Blogging?
Top Blogging Actually Done in 2014
As a follow-up to yesterday’s post about what draws the most traffic here, I went through and pulled out the top 20 posts from the blog (by traffic) for the calendar year 2014 that were first published in 2014. Numbers after the links are the fraction of the total pageviews for the year that each… Continue reading Top Blogging Actually Done in 2014
