Next, repeat the test but, first, give both shafts a good tap on the side with a sledgehammer. Steel is still a much more resilient material in many respects. Carbon fiber is an exciting material that's going to find it's way into more and more things (making them more awesome) as it becomes a more affordable… » 2/12/14 11:43pm 2/12/14 11:43pm

We've been using chip&pin in Canada for several years, but magnetic stripes are still the ubiquitous fall-back. You can swipe if something causes the chip to fail, or just start-out swiping. I'm not sure if we're really out ahead in terms of security so far because of this. On the other hand, one thing this article… » 2/12/14 5:55pm 2/12/14 5:55pm

When I was growing up we were taught, in school, to stretch before playing sports to prevent injury. This was logically argued, practiced in gym class, and nowhere else. When I played Hockey we skated and took practice shots to warm up before games (Note: I was not a goalie. Goalies are *special*.). When I played… » 2/12/14 5:20pm 2/12/14 5:20pm

I grew up in a province (in Canada) that has long been viewed as the most religious, conservative, and backwards. The city I grew up in was a whisky trading fort just over a century ago. The settlers were practically all Catholic and, despite massive immigration rates, that's still the dominant religion. The city I… » 2/07/14 3:12pm 2/07/14 3:12pm

It's been a while since I saw photos of the Chinese F-35 knockoff prototypes, but it looked like they omitted the V/STOL fan and slimmed down the fuselage. The resulting plane, were everything else equal, would be lighter and create less drag, resulting in a better dog-fighter. Note that even the non V/STOL versions… » 2/04/14 11:42pm 2/04/14 11:42pm

Director's cuts of movies have been with us since the 80's, but it's fascinating how the redux of old films and TV shows is taking off. A redux does not involve merely adding or removing minor amounts of existing material, but the creation of new shots, effects, etc. Some early attempts, such as Lucas' various… » 1/27/14 3:01pm 1/27/14 3:01pm

Well, it's not good. Actually, it's awful, but it could have been great. Ayn Rand's "Atlas Shrugged" would be awesome if it were a satire of right-wing wonks rather than an earnest tale. I read this in grade school and, up until about halfway through, thought it was a hilariously over-the-top satire. The forces… » 1/22/14 3:18pm 1/22/14 3:18pm

Altering your diet to reduce your caloric intake while increasing your physical activity will absolutely work every time, provided you can actually stick to the changes (permanently)! Choosing the right foods to eat can greatly reduce the willpower you'll need. Eating lots of fiber, protein, and healthy fats will… » 1/09/14 1:06am 1/09/14 1:06am

I'm a physicist, but I picked up an English minor -1 course in undergrad. Why did I stop just one course short of that minor? I took the literary criticism course. It wasn't hard. It was ridiculously easy in fact. However, it was complete and utter BS. It destroyed my soul a little to see resources wasted on… » 12/25/13 2:22am 12/25/13 2:22am
