The Evolution of a Sad Balloon

A few years back, I did a couple of posts on the physics of a sad balloon (that is, a helium balloon that can no longer lift itself up to the ceiling), the first on simple buoyancy, the second on how long it takes for the helium to leak out. These were based on only…

042/366: Distortion

For the 42nd installment of this photo-a-day thing, it seems appropriate to try to do some SCIENCE! to get an Answer. So, here’s a composite of a bunch of images I took yesterday in order to investigate something: OK, this needs some explanation… So, I do a lot of shooting with moderately wide-angle lenses (either…

039/366: Mist Vortex

Friday was yet another heavy kid-wrangling day, as the Pip had a minor surgical procedure in the early morning, which required general anaesthesia. This was done before 9am, but we had to keep him home from school for the day to watch for ill effects. Of which there were none, so he and I went…

038/366: Cloudy Conjunction

In yesterday’s crude astrophotography post, I mentioned that the conjunction of Venus and the Moon would be closer this morning, but I took a shot of it yesterday because there’s no telling with the weather here this time of year. When I first went outside this morning, though, the sky was beautiful and clear and…

037/366: Morning Star and Moon

One of the few problems with the new camera is that the Canon software that talks to it only runs on my laptop, not my home desktop. This is an issue partly because the laptop has less disk space (I got it with the biggest SSD available a few years ago, which is small compared…

027/366: #SuperBloodMoon

Really, was there any question at all what the subject of today’s photo would be? I mean, I’m a geek, I have a fancy camera– of course I was taking pictures of the lunar eclipse. But more importantly, I was sharing it with SteelyKid: That’s SteelyKid looking through her telescope at the early stages of…

014/366: Summer Stars

Today was Rosh Hashanah– happy new year to those who celebrate it– meaning that both SteelyKid’s school and The Pip’s day care were closed. In an effort to maintain my sanity while keeping them entertained, I took them to the local science museum to rampage through hands-on exhibits. We also caught the planetarium show, because…

002/366: Boids

I spent a while this morning typing on my laptop on the deck, and brought the new camera out with me for occasional procrastination. The shady spot at that hour has a nice view of the bird feeder, and I snapped a few shots of these guys feeding (using a telephoto lens): (I cropped and…

I forgot to do this last week, because I was busy preparing for SteelyPalooza on Saturday, but here are links to my recent physics posts over at Forbes: — What ‘Ant-Man’ Gets Wrong About The Real Quantum Realm: On the way home from the Schrödinger Sessions, I had some time to kill so I stopped…

Science Talks and Pick-Up Hoops

Over in Tumblr-land, Ben Lillie has an interesting post on all the stuff that goes on behind the scenes of a science talk. It’s an intimidatingly long list of stuff, in quite a range of different areas. But this is a solved problem in other performance fields: And that raises and interesting question, since aside…
