No, it’s not the name of a new reality TV show, though the early auditions would be fun to watch if it were.

The Canadian Space Agency began its latest recruitment campaign in May and over 5000 candidates had registered for two positions when the deadline closed last week. The list will narrowed down to a 120 who will undergo physicals in September. Of those, about 15 candidates will be left next April.

The Canadian Press reports that this is just the third time since the creation of the Canadian Astronaut Corps in 1983, that Canada has added new space explorers to an exclusive group of astronauts.

The winning candidates get a starting salary of  $83,3000.

Paint often wrinkles—but sometimes it cracks. This seems odd, he points out, because in wrinkling, things are pushed together, whereas cracks form when things are pulled apart. What accounts for these antithetical behaviors?

Read about the science of drying paint, elephant wrinkles, fluttering flags and more in this article from Harvard Magazine.

I was surfing before bedtime and saw this. I’d really love to try this, but I’m not sure I would if Scotchguard contains perfluororoctanoic acid. I’ll have to see if there’s an ingredient list on the can.

NASA is inviting members of the general public from around the world to suggest a new name for the Gamma-ray Large Area Space Telescope, otherwise known as GLAST, before it launches in mid-2008. GLAST is designed to probe the most violent events and exotic objects in the cosmos from gamma-ray bursts to black holes and beyond.

To submit a suggestion for the mission name, visit: http://glast.sonoma.edu/glastname

Anyone who drops a name into the “Name That Satellite!” suggestion box on the Web page can choose to receive a “Certificate of Participation” via return e-mail. Participants also may choose to receive the NASA press release announcing the new mission name. The announcement is expected approximately 60 days after launch of the telescope.

David was very excited today to learn that paleontologists have discovered a nearly complete fossil of a hitherto unknown species of dinosaur in Patagonia.

The herbivorous Futalognkosaurus dukei measured an estimated 105 feet to 112 feet from head to tail and was as high as a four-storey building. It is one of the three biggest dinosaurs yet found in the world.

And here’s proof that with enough money you can have anything named after you…

Futalognkosaurus dukei’s name is derived from the indigenous Mapuche language meaning “giant chief of the lizards”, and the name of U.S. power company Duke Energy Corp, which financed a large part of the excavation in Argentina.

David went digging through the workbook shelf today and uncovered the AEP’s “The Complete Book of Our Solar System “. It’s a tough book to work through, with lots of copy work, but he kept at it for a lot longer than I anticipated. I have to admit that there’s a good variety of activities and puzzles, so that it seemed worth the effort to get through the more dull pages to get to the games or riddles.

After working through about 15 pages, we went outside and collected autumn colored leaves. We put them in his nature journal, then spent time identifying them with a leaf identification book I didn’t even know we had.

Then he decided it was craft time, so we made some monster  paper lanterns that turned out kind of cute.

Now it’s nearly nine o’clock, and I’ve still got a bundle of work to catch up on before I can get some sleep, so I sent David off to watch a few shows on TV before he heads to sleep. I hate to condone TV, but sometimes I need the solitude to pay the bills.

I still can’t believe how lucky I am to be able to watch him grow and learn. As much as it can be exhausting some days, I wouldn’t trade it for the world.

Mr and Mrs American Goldfinch seem to have moved in to the maple tree in front of our house and plan to start a family.  They’re very pretty, and we’re glad to have them.

 Unfortunately, Mr Goldfinch is being macho and when he sees his reflection in my office window, he’s convinced it’s his competiton. Ever since I got back from vacation yesterday afternoon, Mr Goldfinch has been fighting with my windows. I’m rather concerned about him. Or, at least about the state of his beak.

He was making such a fuss, that I didn’t even notice his lady until this afternoon, when I spotted her in the tree. She was watching the commotion with a bemused look.

After doing a bit of research to see if there’s anything I can do to help Mr Goldfinch save his beak, I’ve discovered that I’d need to cover the windows from the outside (difficult since they’re on the second floor), and it might not even help, as the stubborn guy would probably spend enough time searching for the missing competition that he’d find one or more of the other windows on our house, or our neighbor’s.

So, for now, I’ve settled for recruiting David’s help to wave our arms near the window  whenever he starts his attacks, which seems to send him away for a while.

For the last few months, David’s bedtime ritual has included a few chapters of what he calls, “Jack and Annie stories,” more commonly referred to as The Magic Treehouse books by Mary Pope Osborne.

After picking up books in no particular order from used bookstores, we finally decided to fill out the rest of the series from Amazon.com, so we’ve got a full set up to #34. There’s more to collect, I know, and it appears that the author has not yet run out of ideas, but 34 books is a pretty good start, in my estimation, so we’ll leave it at that for now.

David has decided that he wants to read the entire series, in order, this summer — partly because we discovered the official series website and printed off the “passport“. So, we’re starting with #1, reading a book every two or three nights, and of course, collecting the passport stamps along the way.

I decided, after reading the first part of Dinosaurs before Dark this evening, that I may as well find related coloring pages, books and activities for David to work on during the days and mornings to expand on the event or place in the Magic Treehouse books. So, every few days I thought I’d post a Magic Treehouse tie-in to the book we’re at.

The first, of course, is Dinosaurs Before Dark

I do love iTunes. I don’t buy, or even listen to, a lot of music, but the iTunes podcast directory is simply awesome. My computer is filled with over 25 gigs of podcast material, about half of which I haven’t had time to listen to yet.

Today I upgraded my software, and the first thing I noticed was a new link to something called iTunesU , which contains links to podcasts of courses and lectures from a wide variety of universities.

I’ve been a huge fan of the podcasts from UC Berkeley for quite a while now, but there are some really fascinating looking course podcasts in iTunesU that I missed completely from other institutions. I’ve started subscribing to all of them… though I have no idea when I’ll have time to listen to them all.

If you’re looking for a fun and interesting course to listen to, my favorites from UC Berkeley are:

• European Civilization from the Renaissance to the Present — a nice, well presented overview. Good for audio only listening.
• Introduction to General Astronomy — the lecturer in this course is worth watching in the video version.
• Earthquakes in your backyard - This is a totally fascinating course, and not too hard to follow. It’s in audio only, but be sure to check out the course website to download the supplementary materials, which make it understandable.
• Man, God and Society in Western Literature — some of the audio in this one is really bad and/or missing, which sucks because this is a really great series of lectures, especially if you follow along with the readings.

School of Thought posted this page with Singing Science songs in MP3 format.

I downloaded them all and am burning my favorites to CD. Some of the songs there are great fun. My favorites are “What Makes the Weather”, “Why does the Sun Shine”, and ” Kinetic And Potential Energy”

Most of the others are good for a giggle or two. Some are outright hilarious.
