How to Make a Chicken Walk like Dinosaur

lucky760 says...

Me neither, but here's the explanation from above:

Chickens raised wearing artificial tails, and consequently with more posteriorly located centre of mass, showed a more vertical orientation of the femur during standing and increased femoral displacement during locomotion. Our results support the hypothesis that gradual changes in the location of the centre of mass resulted in more crouched hindlimb postures and a shift from hip-driven to knee-driven limb movements through theropod evolution.
If you watch the upper-legs, you may see the difference, but it would definitely be much improved to have the two chicken videos side-by-side. So interesting that they raised the test chickens with the tail always affixed to them.

TARSplay

The robots were in some ways some of the most reasonable ones I've seen in movies. The balancing when moving in the way shown here would pose definite problems, but they had a variety of locomotions (I liked the fastest rotating one the best) and the joints between the pieces at least looked like they'd be fairly easy to make very solid and robust. Though the fittings between the pieces looked pretty tight, so basically if you got a rock stuck in there... Yeah... Some issues.

Other than that overall the movie was a very meh experience, and I was so disappointed by some of the physics (mostly the basic one, particularly the airlock explosion somehow causing the craft/station to de-orbit... How exactly?) that I almost wrote it off at that point. Luckily the ending kinda pulled it together again so it wasn't on the whole unpleasant, even though they hammered it in way too much.

A Cool Old Steam Train In BC, Canada

nanrod says...

The CP 2816 Empress steam locomotive, roving ambassador for Canadian Pacific Railways. I happened upon this train in Maple Ridge last December and didn't have my f**king camera with me. Not even my cell phone.

Excited train guy, New York!

Dumb Ways to Die

I love it, the kids all loved it, the wife loved it. As to whether it'll get the message across, I don't know, but I think it's awesome. Considering the number of times recently the trains have been stopped due to death on the line, something needs to be done.

Stop stopping the trains? How much damage can one bipedal cause a locomotive...


Not much, but they spend so much time cleaning up the mess and 'investigating' how the person died... it's way heaps inconvenient to everyone.

But seriously, I've had my train line shut down during peak hour three times in as many months, it's happening quite a bit, so I can see why they felt the need to do something.
