An Adventure in Relative Time Keeping

Better than the light traveling through time experiment, is Tom Van Baak’s experiment in which he outfitted his family minivan with high-precision cesium clocks to demonstrate to his kids that they gained 22 nanoseconds of vacation time on their mountain road trip, compared with readings on clocks left back at home. Time travel in action.

As a collector of vintage and modern atomic clocks, I discovered it was possible, using gear found at home, to convert our family minivan into a mobile high-precision time laboratory, complete with batteries, power converters, time interval counters, three children, and three cesium clocks. We drove as high as we could up Mount Rainier, the volcano near Seattle, Washington, and parked there for two days. The trip was continuously logged with the global positioning system; the net altitude gain was +1340 meters.

Given the terrestrial blueshift of 1.1 × 10-16 per meter mentioned by Kleppner and integrating our altitude profile, we predicted the round-trip time dilation to be +22 nanoseconds. This is remarkably close to what we experimentally observed when, after we returned, the ensemble of portable cesium clocks was again compared with atomic clocks left at home.

You Don’t Know Jack

You Don't Know Jack

I was first introduced to the game “You Don’t Know Jack” by my high school physics teacher almost ten years ago. On the last day of classes he let us chill out and play the addictive flash based game where high culture and pop culture collide; I’ve been a fan ever since.

Now you can play a single player version of You Don’t Know Jack online. You can also browse their older “Dis or Dat” games via their blog or after you finish the 7 question game.

Time Travelling Light Waves

Light Lab at NEC Research Institute in Princeton, N.J.

This is a bit of old news, but it’s interesting.

Back in 2000 Scientists figured out a way to make a pulse of light travel faster than the speed of light. Wait until you hear exactly what they did; it might have been a few years ago but it will still blow your mind.

Scientists from the NEC Research Institute in Princeton, N.J did an experiment which caused a pulse of light, a group of waves with no mass, to come out the other side of a specially prepared chamber before it was even done entering.

From CBC News:

Inside a chamber, they changed the state of a vapour in a way that light travelling through it would travel faster than normal.

When the pulse of light travelled through the vapour, the pulse reconfigured as some component waves stretched and others compressed. As the waves approached the end of the chamber, they recombined, forming the original pulse.

The key to the experiment was that the pulse reformed before it could have gotten there by simply travelling through empty space. This means that, when the waves of the light distorted, the pulse traveled forward in time.

I’m not sure that it means anything in the grand scheme of things because they say they don’t know of any way to turn this phenomena into a way to carry data.

Captain Cunuck

I heard the news today that Captain America is dead1

This got me thinking about a Canadian I met when I lived in Utah, back in 1999. His “claim to fame” was that his dad, Richard Comely, created the comic book, Captain Cunuck (wikipedia).

Captain Cunuck

This guy used to brag about how much better Canadians were than Americans. He relished in the pleasure of pointing out any remotely interesting Canadian accomplishment and all the while derided our neighbours to the south. While my primal instincts told me to admire this man for his obviously superior intellect, not so deep down I realized it was a pretty jerky way to be and I figured all he was really accomplishing was to make them dislike us. He didn’t care, and although he was friendly enough to me, he wasn’t a particularly popular guy living in middle America.

Canada/US relations aside, learning about Captain Cunuck was kind of intriguing. Here was this super hero that I had never heard of, and probably never would have heard of, but yet there was something alluring about the fact that there even exists a comic set in Canada. They used famous Canadian landmarks as backdrops and even the characters had particularly Canadian background—Captain Cunuck’s alter ego works for the RCMP—and yet, he is a super hero.

This might not seem like a big deal for American’s who have lived their lives seeing whom and what they expect to see; his or her country, familiar landmarks, and national in-jokes; casually depicted in TV, movies, and comic books. But for me, this was something completely new. The closest thing I had ever known as a Canadian super hero before this was Wolverine (this X-Men character is from southern Alberta), but despite the fact that he was born somewhere near Lethbridge, he’s still an American icon.

I found a tribute site for Captain Cunuck, and this is how that fan remembers the comic:

Captain Canuck was like its American progenitors: a pulpy, action-adventure series, with plenty of running about, narrow escapes, and two-fisted thrills. What made it “different” was a willingness to have actual plots!

How many U.S. superhero comics have you read where the first issue of a two-parter starts out great: intriguing set-up, interesting characters are introduced, you can’t wait for the continuation… and then you get the continuation and it’s just one long fight scene: no plot, no story development, no characterization. In Captain Canuck there were plot twists, surprising changes in direction, and a sense you were reading an actual story, not just a vignette. There was also some nice dialogue and easy badinage between the characters that a lot of U.S. comics lack, even today — a real plausibility to some of the lines.

Isn’t it telling how even in a comic book description, Canadians compare ourselves to the US. Anyway, here’s to Captain Cunuck, a true Canadian hero. Oh and Americans we’re sorry about your namesake super hero taking a bullet.

A little tidbit of my own Canadian-esque bragging… Superman—that’s right, the Man of Steel—was actually co-created by a Canadian. This pleases me, but I’ll be the first to admit: nothing says America more than Superman, so we can’t even pretend to claim him… at least not publicly. So every time he flies to his fortress of solitude up in the Canadian arctic, we can just quietly think to ourselves, welcome home, Superman.

  1. For those of you worried about the death of Captain America, don’t worry, this is just an old trick by the comic book industry to boost sales. Remember, resurrections are not exactly rare in the world of comics, and Marvel Entertainment editor in chief Joe Quesada has already stated that a Captain America comeback wasn’t impossible.[]

There have been countless times when friends or family have asked me to help them setup their home network. Something that comes in extremely handy is a list of default passwords for a huge selection of routers—hopefully including theirs, without which you might actually have to read an instruction manual.

Nintendo Entertainment System Documentary

It’s hard to believe that the Nintendo Entertainment System was released 21 years ago. Last year, GameSpot sponsored a documentary celebrating the early years of Nintendo.

I particularly enjoyed the demonstrations of how to make your Nintendo cartridges run. I recall that for the first few years of Nintendo playing at our house we never had to blow on the games, I guess it was only in the later years (early 90’s) when games weren’t babied so much that dust was allowed to collect on the exposed circuit boards, and the ritual of blowing on games before you loaded them began.

Here it is, Flashback NES:
