No caterpillar soup for you!

Laura It has always been thought that when caterpillars metamorphize into moths or butterflies their bodies and brains are completely rewired. As one scientist picturesquely described it: “People always thought that during metamorphosis the caterpillar turns to soup and all the ingredients are rearranged into the butterfly or moth”.

However, recently some researchers trained caterpillars to perform a task (caterpillar has to crawl through Y-shaped tube; one side smells of ethyl acetate and produces a shock, other side has no smell and gives no shock). The larvae turned into moths and then got re-tested. A huge percentage of them (77%!) still correctly performed the task.

So insects’ brains don’t turn to soup when they become adults. So I guess there’s hope for teenagers as well!

Earliest sound recording

Laura For some perverse reason, I’ve always disliked Thomas Edison. Probably it’s because people insist on calling him a genius, rather than merely an intelligent and very successful businessman/inventor. (It’s the same reflex I have when someone calls Bill Gates a genius rather than an intelligent, scarily successful businessman and oh-by-the-way one of the richest men on earth.) So I was secretly pleased when I read that some researchers this month found a recording of a human voice that predated Edison’s by nearly two decades.

On April 9, 1860, Frenchman Édouard-Léon Scott de Martinville recorded sound via a phonoautogram machine, which depicted the sound as a bunch of pen squiggles on paper. The squiggles—a phonoautograph—were a visual representation of the sound only, and never meant to be played back, but through the magic of modern computers were converted into a recognizably human voice singing the first line to “Au Claire de la Lune”.

Edison still gets credit for producing the first sound recording that could be reproduced, but it’s nice to see Scott—the man who managed to actually record sound first—get his due.

Catching Up

Peter Sorry for the lack of blogging, work’s been crazy here. And when we’re not working for money, we’re trying to get some other things started. I know, I know, boo hoo. Anything not to clean the house.

So, where did we leave off? Ah, yes. The ROM.

Well, both due to paternal instinct and the fact that I had already hinted something to Jon (so he was nagging me every two seconds!!), when we got home I called Rogers.

You see, I had noticed a Rogers ad boasting a new way of picking channels.

During this year’s trip to Ottawa, Jon was once again transfixed by Météo Média on any TV he could find with it. Which was most, since it is part of basic cable in the Ottawa region (but NOT in outside of Ottawa). So given the Rogers ad, I thought it might be 36 or so bucks a year well spent.

Naà¯vely, I thought this ad meant I could pick up a single extra channel for $2.79. When I chatted with Rogers, it became apparent that this claim doesn’t mean what you think it means. I still don’t understand how it can work, but suffice it to say that we’d have to buy a package for seven bucks a month.

Ack.

The Rogers tech, sensing she had to sweeten this, took the route of all good opiate dealers, and immediately hooked the channel in free for three months. I suddenly heard Jon call from the other room in a voice so stressed it sounded like someone was throttling him. “Dad! Dad! It’s…on! It’s on, it’s on!” Apparently, she hit the vein.

So, two weeks later Jon is still watching it, even more than his beloved Weather Network, and he’s picked up the days of the week. Example from yesterday: “Hey Dad, on mardi can I have computer?

ROM

Jon

Peter Between snow and good old freelance work, we were stuck inside the first half of March Break, but we finally got out late in the week. We decided to head out to the ROM to see how Jon would take to dinosaur skeletons and other fun museum stuff in the new ROM crystal.

We talked a good game in line. Maybe we’d even spring for a membership, if he liked it. We could come back often…

Welllll, not so much. Jon was prepped and ready, and looked at the first dinosaur skeleton we happened upon, a velociraptor-esque creature of some kind, and tried to figure it out, to parse it. It was very, very difficult for him. I pointed out the teeth and claws, and he studied them, but even then you could see him starting to shut down.

Barosaurus skeleton
The barosaurus

Later I pointed the enormous barosaurus’s tail, the stegosaurus’s tiny head, the ancient sea turtle and the pterosaur above us. And he’d gamely look at the shapes or pieces, and maybe he even made them out, but the complexity of the skeletal forms was too difficult to get a handle on. Pretty quickly his eyes (that is, his visual cortex) were tired, and he retreated into his iPod. This was okay: the room was quickly filling and the noise (which tends to compress Jon) was bouncing off the echo-y angled walls. But I should add that Jon did occasionally try to look, and he was very patient and didn’t get upset at all.

Oooh, check out the wing leather impression left in the fossil. They really did have a diamond-shaped membrane at the end of their tails!

archeopteryx
Ten points to the first person who comments the name of this one below. Ten more points for the species name, and 50 for someone who can say why without looking it up. You’re on nerd’s honour. Anybody?

After the two rooms of dinosaurs and mammals, we scooted into another room. It was filled with antique typewriters prior to any kind of standardization. I tried to get Jon to guess what was in the display cases, but even as he looked at them all he could guess was dinosaurs, and he was a tad stressed. I asked if he could see letters and he blinked and said “Keyboard…” and all of the stress drained out of him. He was in his element. I explained that they were typewriters, what we had before we had computers, but he cut me off “Gingi has a typewriter!” He knew all about typewriters. Gingi is his school’s amazing art teacher (and, while I’m here, a victim of poorly thought out administrative cutbacks that has made her job basically untenable. Don’t get me started.)

Jon in the Early Typewriter room
Fake smile #2, but he’s way more relaxed, even enjoyed reading the sign behind him.

We headed down to the Darwin show (no cameras allowed). Jon was patient and mainly focused on his iPod while we explored the show. It took you through the man’s life with many facsimiles and a few real holograph writings, and possessions (and a lot of his flower pressings!). I was fascinated by the latter half of his life, as he sat on his realization, read a great deal on all sorts of topics and examined his theory from a great many points of view. He was incredibly prescient about the immense storm this would cause on society, and sadly still does. Shockingly (to me) the touring show has not had a single corporate sponsor since it started at the American Museum of Natural History in 2005. When it got to Toronto, it picked up its first two sponsors: the Humanist Association of Canada and The United Church Observer, which suggests that I could probably buy a sponsorship myself, with grocery money. An extremely sad commentary on both the intellects and the cajones of today’s corporations.

In the end, we headed out for a grand lunch of hot dogs and Greg’s Ice Cream. Greg was even there, so we got to chat with him (he and Jon talked new puppies). A fine end to March Break week.

Méteo Média

Jon Mar. 15/08

I watched Méteo Média on TV. On Méteo Média I saw Prévision Local witch is French for Local Forecast. I like to watch the highway conditions in French. The French word for the highway conditions is conditions Routiers. I saw Prevision international witch is French for international Forecast

Jon

(Jon usually knows how to spell “which”, but he was in an extremely high state of excitement since we had just added the French version of the Weather Network to our cable that day. We’ll see if it outlasts the free 3-month trial period—$7 a month for the French package is a bit steep just so that Jon can enjoy one channel. Though he is learning some French words as well as learning how to do accent marks on the computer keyboard; that’s worth something! —L)

Wii

Jon Mar. 13/08

I started off with Super Mario Galaxy and I had to use the nunchuk. And after Super Mario Galaxy Mommy switched to Wii Sports. In Wii Sports I did my Wii Fitness test. My Fitness results were 70.
That was a pretty good score.
