Here's a fascinating time-lapse picture of the night sky, taken in Toronto last month.
There's also a wonderful video showing the image as it's built up over time, starting with a dark sky and then filling in with the plane, helicopter and star trails. You can click the image to see a larger version, which was taken by wvs and shared via the same Creative Commons license I utilize for most of my images.
I realized I haven't taken any photos of my fluorescent minerals using a digital SLR. I decided it was time, and took a practice run a few days ago. The results are promising, though I can see some areas for improvement.
All of the minerals below are from the Franklin/Sterling Hills area of New Jersey; famed for their bright and vivid colors when illuminated by short-wave UV light.
In terms of color, the red is calcite, and the green is willemite. They are the 2 most common minerals. Next is clinohedrite, coming in with the orange, except in the case of the wollostonite, which is also orange, and finally, the purple colored hardystonite.

Here's a link to a fascinating video. Taken from the space shuttle, this 10 minute video shows photos of cities at night from around the world. Check out the spoke based cities of Europe and how they contrast to the grid-based cities of the American west. The photos were taken using a home-made barn-door photography platform, which was used to compensate for the earth's movement. It's very rare that I watch videos of this length, and in fact I thought I would just take a quick look, but it's so fascinating to see these cities from above, at night, that I watched the whole thing without noticing the time.
On February 4th, 2 months before his assassination, Martin Luther King gave a sermon at Ebenezer Baptist Church in Atlanta. The sermon was on the topic of the "Drum Major Instinct", and deals with how we all, in various ways, are tempted to give in to the temptations of "keeping up with the Joneses," and the problems associated with such pursuits.
An interesting sermon, to be sure, and worth reading, but the "Drum Major Instinct" is most well known as the source of the eulogy for Martin Luther King. You can read (or listen) to the entire sermon: Drum Major Instinct.
In my own DMI way, I almost began this posting with an observation of how old I feel, given my age when MLK was killed 40 years ago. It's true, though, so there it is, but this post isn't about me; it's about someone whose positive impact on our country's history is yet to be fully appreciated.
I'll further note that as I get older, and realize it's very hard for one person to change the world, it's actually not too hard to change the world, one person at a time.
Below is the conclusion of the sermon, where he speaks of how he would like to be remembered.
Drum Major Instinct
Every now and then I guess we all think realistically (Yes, sir) about that day when we will be victimized with what is life's final common denominator--that something that we call death. We all think about it. And every now and then I think about my own death and I think about my own funeral. And I don't think of it in a morbid sense. And every now and then I ask myself, "What is it that I would want said?" And I leave the word to you this morning.
If any of you are around when I have to meet my day, I don't want a long funeral. And if you get somebody to deliver the eulogy, tell them not to talk too long. (Yes) And every now and then I wonder what I want them to say. Tell them not to mention that I have a Nobel Peace Prize--that isn't important. Tell them not to mention that I have three or four hundred other awards--that's not important. Tell them not to mention where I went to school. (Yes)
I'd like somebody to mention that day that Martin Luther King, Jr., tried to give his life serving others. (Yes)
I'd like for somebody to say that day that Martin Luther King, Jr., tried to love somebody.
I want you to say that day that I tried to be right on the war question. (Amen)
I want you to be able to say that day that I did try to feed the hungry. (Yes)
And I want you to be able to say that day that I did try in my life to clothe those who were naked. (Yes)
I want you to say on that day that I did try in my life to visit those who were in prison. (Lord)
I want you to say that I tried to love and serve humanity. (Yes)
Yes, if you want to say that I was a drum major, say that I was a drum major for justice. (Amen) Say that I was a drum major for peace. (Yes) I was a drum major for righteousness. And all of the other shallow things will not matter. (Yes) I won't have any money to leave behind. I won't have the fine and luxurious things of life to leave behind. But I just want to leave a committed life behind. (Amen) And that's all I want to say.
If I can help somebody as I pass along,
If I can cheer somebody with a word or song,
If I can show somebody he's traveling wrong,
Then my living will not be in vain.
If I can do my duty as a Christian ought,
If I can bring salvation to a world once wrought,
If I can spread the message as the master taught,
Then my living will not be in vain.
Good advice, no joke.
Whenever you're called on to make up your mind
And you're hampered by not having any
The simplest way to solve the dilemma you'll find
Is simply by flipping a penny
No, not so that chance shall decide the affair
As you're passively standing there moping
But as soon as the penny is up in the air
You'll suddenly know what you're hoping
Thanks to Nelson for passing this along.
