The other day, my wife suggested a Carnegie Science Center-related post. Only once before — in 2003 — has she volunteered a topic like that, so I took her up on the offer. I’ve noticed that, on every trip to the CSC, my wife slips away to browse the museum store while I’m watching the…
Why don’t states require students to take four years of English and math, and three or four years of science? Why isn’t there a class dedicated to teaching the fundamentals of writing? For that matter, why don’t we require more than two years of history or social studies and foreign language? The students want it—69…
July 20, 1969: astronauts from Apollo 11 visited the lunar surface. The Atlantic.
Yes, the Mars rovers are cute and wonderful, but I do feel bad that my kids didn’t have the space shuttle program to look forward to, as I did. Okay, the dramatic music and the studio lighting on the talking heads may be a notch or two over the top. But there’s no argument from…
Imagination is a powerful social tool. The novel provides us with a sustained window into another world, while still exercising the creative faculties that make us co-creators of the worlds we read about. Having said all that, I am aware that there may be some confirmation bias operating, as I here introduce an article that…
Good example of journalistic storytelling, delaying the ending of the story a bit to keep you reading, without appearing to be deliberately coy. (We know from the headline that the story ends happily.) This is a medical container. Inside is a trachea, a carefully constructed human windpipe, seeded with 60 million stem cells from a…
In November of 1964, Frank Plaskon, of McKeesport, was a 24-year-old Special Forces Ranger out of Fort Bragg, N.C. Frank was part of a team dispatched to the USS Requin now berthed on the Ohio River at the Carnegie Science Center. “And I can’t believe that 48 years later it’s right here in my hometown,”…
This is not encouraging. The scientists tested three types of soap dispenser, in both lab and real-world settings. Of the three variants, the dispensers that were refillable from a giant bottle of liquid soap were by far the filthiest, leading to a 26-fold increase in handwashers’ bacteria levels. —Health – Brian Fung – Soap: How…
From “global warming” to “climate change” to “ecosystem management,” the buzzwords have changed, but the issue remains: enthusiasm and hype are part of the PR machine that drives the public perception of science. When well-meaning activists rely on emotions as a shortcut to get the cooperation of the public, the fabric of civic discourse is…
I won’t be showing this to my daughter. I might instead show it as part of a media studies unit, as an example of a self-made PR disaster. http://www.youtube.com/watch?v=oZtMmt5rC6g Update: I didn’t think that would stay up for long in its original location. Here’s a copy: http://www.youtube.com/watch?v=g032MPrSjFA
This summer, I’m a “CSC Insider” — meaning that I’m getting some VIP treatment, in return for blogging twice a month about the Carnegie Science Center. First off, I attended the opening night gala for Guitar: The Instrument That Rocked the World. I also went back with my family the next day. (The video shows…

Perhaps our most dangerous bias is that we naturally assume that everyone else is more susceptible to thinking errors, a tendency known as the “bias blind spot.” This “meta-bias” is rooted in our ability to spot systematic mistakes in the decisions of others—we excel at noticing the flaws of friends—and inability to spot those same…
WHY have we been told that salt is so deadly? Well, the advice has always sounded reasonable. It has what nutritionists like to call “biological plausibility.” Eat more salt and your body retains water to maintain a stable concentration of sodium in your blood. This is why eating salty food tends to make us thirsty:…
When I am insanely busy during the academic year, I relish the time before I fall asleep, as time I can think about anything at all. If it’s productive and interesting, I’ll stay awake. If not, well, then I won’t waste much time before I conk out. In an attempt to carve out enouth time…
Scientists now believe that much of the life on Earth is barely able to fog a mirror, as it were. The deep-sea microbes may be an extreme example of a laid-back norm. Most of Earth life, measured by numbers, is not rambunctious and charismatic like life in the sunshine, nor is it akin to the…
I love a good infographic. HubbleSite – NewsCenter – Hubble to Use Moon as Mirror to See Venus Transit (05/04/2012) – Release Images.
Interesting implications for the flipped classroom. If students think they already understand something, they’ll tune out of a video lecture. Students watched a science video they frequently described as “clear,” but in a post-test it turns out the video had actually confirmed their incorrect assumptions. When students watched a second video that first presented and…
My students are finishing up Hayles, My Mother was a Computer. Some years go, I remember seeing a video of a little girl in a martial arts uniform, barking out “Know what you want! Make a plan! Add a role model! Review your progress!” over and over again, while kicking, chopping and spinning. Her philosophy…
