drorzel | January 22, 2015One of the cool things about working at Union is that the Communications office gets media requests looking for people to comment on current events, which sometimes get forwarded to me. Yesterday was one of those days, with a request for a scientist to comment on the bizarre sports scandal surrounding the deflated footballs used in the AFC Championship game this past weekend. Which led to me doing an experiment, and writing a short article for The Conversation:
News reports say that 11 of the 12 game balls used by the New England Patriots in their AFC championship game against the…
drorzel | January 22, 2015One of my favorite Christmas presents this year was a Seek Thermal camera to use with my Android phone. This allows for a lot of idle physics-y fun, taking pictures of things in thermal mode.
One idea I had was to do a sort of follow-up to the test of my insulated mug that I did a couple of years ago with a PASCO thermocouple probe. That showed a really dramatic difference between my metal IQC water bottle and the insulated mug, in terms of the rate at which hot water placed in each cooled. So, how do these look in thermal imaging?
Well, I took my insulated mug (actually a different one than…

Poor, poor, pitiful Dr. Bob.
For those of you not familiar with him, I'm referring, of course, to Robert "Dr. Bob" Sears, MD, the antivaccine-sympathetic (or, more appropriately, antivaccine-pandering) pediatrician in Capistrano Beach, CA (between Los Angeles and San Diego in Orange County) known for his Vaccine Book, a veritable font of antivaccine misinformation gussied up as a "reasonable" middle ground. Too bad it's not.
In any case, in the wake of the Disneyland measles outbreak, Dr. Bob has found himself under a lot of criticism, along with our "good buddy," the other famous…
drorzel | January 20, 2015(When I launched the Advent Calendar of Science Stories series back in December, I had a few things in mind, but wasn't sure I'd get through 24 days. In the end, I had more than enough material, and in fact didn't end up using a few of my original ideas. So I'll do a few additional posts, on an occasional basis, to use up a bit more of the leftover bits from Eureka: Discovering Your Inner Scientist...)
One of the tricky things about writing this book was that I didn't just need stories from the history of science, but stories that fit a particular pattern. The point of the book, after all, is…
drorzel | January 20, 2015(That title doesn't quite scan as is, but if you stick an "a" in there, you can sing it to the tune of a song from "Fiddler on the Roof"... You're welcome.)
The last time I taught my "Brief History of Timekeeping" seminar was in 2012, so I spent a bunch of time on the Mayan calendar. This time around, we've lost the obvious pop-culture hook, but it's still so weird and fascinating that I spent a class on it last week. One of the things we talked about was what this system (what we know of it) says about the Maya concept of time. There's a very obvious contrast between the interlocking…
drorzel | January 16, 2015I'm teaching my "Brief History of Timekeeping" class again this term, and as always, I'm tweaking things a bit. This is one of our "Sophomore Research Seminar" courses, intended to introduce students to academic research, so it's not specifically a physics class, but I'm choosing to take the statements about research outside the student's field at face value, and thus will be requiring them to do final projects involving some empirical measurement of the natural world, that being the essence of scientific research. (Last time, I included that as an option, but nobody took it, so I ended up…

It looks like this year's going to be a bad flu season.
Hard as it is for me to believe, it was only five weeks ago when I discussed an announcement by the CDC that this year's flu vaccine would likely be less effective because it isn't a good match for the influenza strains in circulation this year. Those familiar with how the flu vaccine is developed every year know that the composition of the vaccine depends on the WHO's choice of the three or four strains that its experts deem most likely to cause significant human suffering and death in the coming flu season. Basically, the WHO has to…
drorzel | January 15, 2015SteelyKid missed the bus this morning-- she was dressed and ready, but I was talking to Kate, and if there isn't a person at the end of the driveway when the bus comes around the corner, they won't stop. So I drove her over to school myself (which is faster, anyway). The GE research lab complex is behind her school, so there's a nice view from the parking lot to the eastern horizon, where the sun was just poking over a big band of clouds.
"Hey, look at that cool sunset!" she said as we were walking from the car to the building.
"That's not a sunset, honey, it's a sunrise. It's morning."
"Oh,…
drorzel | January 15, 2015"Daddy, ask me a math problem."
"OK. What's 18 plus 6?"
"Ummm... 24."
"Correct."
"See, I just keep the 18 and then add 2 from the 6 to get 20. That leaves 4 from the six, and 20 plus 4 is 24."
"Right. Good work."
------
"Hey, SteelyKid. What's 120 plus 180?"
"Ummm... 300."
"Very good!"
"I just added the hundreds to make 200, and then 80 plus 20 is 100, and then I add them all together to get 300."
"Nice work."
"It takes a little while, though."
"Yes, but you keep practicing, and getting faster."
"Practice makes perfect!"
------
"That would take ten minutes, which is... six hundred seconds."

drorzel | January 13, 2015Yesterday's Open Letter to Neil deGrasse Tyson struck a chord with a lot of people, and has spread a good distance on social media, which is gratifying. Given the delocalized nature of modern social media, though, it means I'm having essentially the same argument in five different places via different platforms. In the interest of consolidating this a tiny bit, then, let me post some follow-up stuff here.
-- The most charitable interpretation of the tweet I objected to is that it's meant as praise for good students. The idea being that good students will learn in the absence of good teaching…

Every physicist with the tiniest bit of a public profile gets letters from people with a pet theory to promote. These days, email and social media make it incredibly easy to flood the inbox of…
drorzel | January 12, 2015Dr. Tyson:
(I find the faux-familiar thing people do with "open letters" really grating, so I'm not going to presume to call you "Neil" through the following...)
First of all, I should probably say "Thanks," because I'm using some of your material in my class this term-- I had them read Stick in the Mud Astronomy, and contrast it with wacky Ancient Alien stuff, and gave them a second assignment based on Manhattanhenge, so that stuff's great. And I'm psyched to hear you've gotten your own talk show. So, you know, that stuff's awesome. Thanks.
And I should also note that while I haven't always…
drorzel | January 12, 2015I've decided to do a new round of profiles in the Project for Non-Academic Science (acronym deliberately chosen to coincide with a journal), as a way of getting a little more information out there to students studying in STEM fields who will likely end up with jobs off the "standard" academic science track.
The fourteenth profile of this round (after a short hiatus for relentless book promotion) features the founder of a new crowd-funding platform for physics.
1) What is your non-academic job? I am the Founder and President of Fiat Physica, the world’s premiere physics fundraising platform.…
drorzel | January 9, 2015Two new items about Eureka: Discovering Your Inner Scientist:
1) WAMC has now posted the interview I did with Joe Donahue on The Roundtable. This was a fun interview, and covers a number of examples from the book, so I think gives you a really nice sense of what it's all about.
2) There's a review of Eureka in New Scientist, along with two other books. It's fun to see all these different publications do reviews, because every reviewer latches onto a different example to feature. You can almost deduce the entire contents of the book if you read all of the different reviews...
The New Scientist…
drorzel | January 8, 2015I've been intermittently profiling people with STEM degrees and non-academic jobs since 2009, as it turns out. One of the questions in the profile asks "What’s the most important thing you learned from science?" These have been some of the most interesting responses, so I thought it might be interesting, while I sit here and wait out a two-hour delay in the opening of the kids' schools, to compile those answers through the years.
These are in roughly chronological order, and I've left the names off because... Well, mostly because I'm being lazy, but I can invent a principled reason about how…

So here it is, already a week into 2015. Truth be told, I'm still finding myself having a hard time believing that it's already 2015, but then I say that about every year in early January. Be that as it may, I've already seen one hopeful sign that it could be a decent year when it comes to science refuting claims of the antivaccine movement. In fact, there's already been a study that once again fails to find even a hint of a whiff of a whisper of evidence for a link between vaccines and autism. It comes in the form of a study from Japan published online in Vaccine on January 3 (which, oddly…

drorzel | January 7, 2015Back in December, The Parable of the Polygons took social media by storm. It's a simple little demonstration of how relatively small biases can lead to dramatic segregation effects, using cute cartoon polygons. You should go read it, if you haven't already. I'll wait.
This post isn't really about that. I mean, it is, but it's using it for something dramatically different than the intended purpose of the post. You see, I am such a gigantic dork that when I looked at their toy model, the first thing that came to mind was physics.
(And, in fact, I sat on this post topic for the better part of a…
