Error message

Sometimes astronomy is exciting. You go out, use a gigantic telescope to collect light from a distant star so far away that the light left in like 1700AD. You sit down at your computer and use that light, in the form of a digitally-recorded image, to measure the movement of the star and notice that the star's velocity is changing in a very predictable pattern. Then you get to use that pattern to divine the existence of a planet orbiting a distant sun. You found a planet, a world, another place in the Galaxy! That might be someone's Jupiter that they look up and see in their night sky. Perhaps some alien got excommunicated from their alien church for proposing that their Jupiter orbited their sun, rather than their home planet. Maybe that world you detected from your night of observing inspires poetry and songs among an alien people.

Other times astronomy is less exciting and much more...um...what's the word? Buggy. For example, today I got the following error message:

Ionization (call_external): EOS_list_species - this error should never happen

No other information was given. No advice. No helpful suggestions. Just the fact that whatever happened should never have happened. Ever. Then the program died gracefully, leaving me wondering where it all went so wrong.

Science!

On the Height of J.J. Barea

Dallas Mavericks point guard J.J. Barea standing between two very tall people (from: Picassa user photoasisphoto).

Congrats to the Dallas Mavericks, who beat the Miami Heat tonight in game six to win the NBA championship.

Okay, with that out of the way, just how tall is the busy-footed Maverick point guard J.J. Barea? He's listed as 6-foot on NBA.com, but no one, not even the sports casters, believes that he can possibly be that tall. He looks like a super-fast Hobbit out there. But could that just be relative scaling, with him standing next to a bunch of extremely tall people? People on Yahoo! Answers think so---I know because I've been Google searching "J.J. Barea Height" for the past 15 minutes.

So I decided to find a photo and settle the issue once and for all.

I started by downloading a stock photo of J.J. from NBA.com, which I then loaded into OpenOffice Draw:


I then used the basketball as my metric. Wikipedia states that an NBA basketball is 29.5 inches in circumfe…

Finding Blissful Clarity by Tuning Out

It's been a minute since I've posted here. My last post was back in April, so it has actually been something like 193,000 minutes, but I like how the kids say "it's been a minute," so I'll stick with that.
As I've said before, I use this space to work out the truths in my life. Writing is a valuable way of taking the non-linear jumble of thoughts in my head and linearizing them by putting them down on the page. In short, writing helps me figure things out. However, logical thinking is not the only way of knowing the world. Another way is to recognize, listen to, and trust one's emotions. Yes, emotions are important for figuring things out.
Back in April, when I last posted here, my emotions were largely characterized by fear, sadness, anger, frustration, confusion and despair. I say largely, because this is what I was feeling on large scales; the world outside of my immediate influence. On smaller scales, where my wife, children and friends reside, I…

The Force is strong with this one...

Last night we were reviewing multiplication tables with Owen. The family fired off doublets of numbers and Owen confidently multiplied away. In the middle of the review Owen stopped and said, "I noticed something. 2 times 2 is 4. If you subtract 1 it's 3. That's equal to taking 2 and adding 1, and then taking 2 and subtracting 1, and multiplying. So 1 times 3 is 2 times 2 minus 1."

I have to admit, that I didn't quite get it at first. I asked him to repeat with another number and he did with six: "6 times 6 is 36. 36 minus 1 is 35. That's the same as 6-1 times 6+1, which is 35."

Ummmmm....wait. Huh? Lemme see...oh. OH! WOW! Owen figured out

\begin{equation}
x^2 - 1 = (x - 1) (x +1)
\end{equation}

So $6 \times 8 = 7 \times 7 - 1 = (7-1) (7+1) = 48$. That's actually pretty handy!

You can see it in the image above. Look at the elements perpendicular to the diagonal. There's 48 bracketing 49, 35 bracketing 36, etc... After a bit more thought we…
