Color My World

Color DemoThis is a post I began quite some time ago thinking it would be a quick and easy one, since it concerns a topic I know very well.

But — perhaps due to my own inability to be brief — it turned out to be more involved than expected. Maybe I just have a hard time leaving out all the details. In any event, I set it aside until I had more time.

Then I had an idea for making this post a bit more fun (at least for me). The problem was: I needed to build a theatre! You see, this post is about color and light.

Dimensional Coordinates

you are hereThe maps you find in some buildings and malls have a little marker flag that says, “You are here!” The marker connects the physical reality of where you are standing at that moment with a specific point on a little flat map.

Your GPS device provides your current location in terms of longitude and latitude. Those numbers link your physical location with a specific point on any globe or map of the Earth.

But to fully represent our location, longitude and latitude are not quite enough. (We might be high overhead in a hot air balloon!) To fully represent our position, we need a little more ‘tude, but in this case that’s altitude, not attitude.

We need three (and only three) coordinates to completely represent our location in space. This post is about why.

A Christmas Carol

Scrooge and MarleyMost of us have traditional ways of celebrating or observing the re-occurring events in our lives. An anniversary might call for dinner at a certain restaurant. A promotion or sale might call for buying a round of drinks. The great life milestones—births, graduations, weddings, retirements, deaths—all come heavily freighted with traditional behaviors.

For me, an important tradition at Christmas time is watching—and reading—the Charles Dickens classic, A Christmas Carol! I think it is one of the most engaging, endearing, wonderful and important stories ever. It is a story of redemption and re-discovery of lost joy. And it is an affirmation that how we choose to live our lives matters.

Plus it has ghosts!

Happy Solstice!

StonehengeAs I write this, the 2012 Winter Solstice (and, perhaps, the long-anticipated End of the World) is about nine hours away. At 11:12 “Zulu” time (UTC) tomorrow (12/21; nice palindromic date), the sun passes a certain key spot in its orbit.

After that, due to the Earth’s axial tilt, the days then start getting longer! (At least for those of us in the northern hemisphere. For those in the southern hemi, tomorrow is the sorrowful day when the light begins to fade.) I’ve always liked the view that those sky dragons that have been munching on our sun have had their fill and have moved off to slumber off their repast for six months.

In any event, the days will start getting longer, and that’s cause for celebration. In commemoration of this auspicious day, I offer you this Solstice Greeting…

Storytelling, Chapter 1

This is the first of a series of articles that discuss something I believe is unique to humans. In fact, I think it’s one of the few things we can point to that does differentiate us from the animal kingdom. And it is something that goes deep into our past. It is our ability to use language to create and tell complex stories.

It is also one of my favorite topics. If you’ve read many of my posts, particularly those about movies and TV, you’ve seen me write about my love of stories.

There is an interesting continuum of storytelling modes. Books lie at one end, movies at the other. Plays and TV lie between. The continuum describes — in part — the experience of the audience. Here’s the deal…

What’s the Word?

What’s the word for when you receive new information that alters your way of thinking? In particular, for when you thought things were one way, expected them to be that way, but the new information surprises you.

I used to think it was the word frisson, but that word (from the French, “to be cold”) refers to the pleasant thrill shiver you experience at the awards ceremony just before they open the envelope that might contain your name. Or when you watch a horror movie (assuming you like watching horror movies).

That’s not quite what I mean. There is — at least for me — some thrill shiver associated with learning a new and surprising thing, but I need a word that focuses more on the sense of realignment that occurs to your worldview.

Wednesday Wow!

Welcome to Wednesday Wow, an irregular series appearing from time to time when I want to write about something that made me say, “Wow!” Or which made me say, “Weird!” Or, “Wonderful!” Or possibly even, “Wild!!”

There may also be posts about Widgets, Whirligigs, Wiccans, Waffles, Wallpaper, Whimsy, Wisdom, Wit, Weather, Wind, Winter, Wushu, Wackos, Whatnots, Wherefores or Whatever.

But not about Women, Wenches or Wahines; they’re too special to be limited to a day, even though they often make me say, “Wow! Wonderful!”

Nor will it be about Work, War or Woodlands. Also, no Whining, Whipping, Whispers, Whistling, Windows, Wine or Whiskey. And I’ll try to not be Wanton, Wonky, Whistful or Worrisome. I can’t guarantee I won’t wander into being a Wry Wiseass. And I hope my Words won’t be Wrong, Wasted or a Wreck.

Venus & Mars

A while back I wrote about Yin & Yang and how some opposites are truly opposing (positive and negative) while others are actually the presence and lack of a thing (light and dark, for example). In that article I cited men & women as being genuine opposing pairs, as you can’t consider either one the absence of the other.

That, understandably, generated some comments. Many would not choose to see women & men as being opposites at all, but as two variations on the theme of human. I think that is absolutely correct. Our two human sexes have far more in common than they do in opposition. (And note that gender is a different concept than sex. Gender is about how your mind works, about who you are; sex is about your genetic code.)

And yet… Anyone who lives in the real world knows that the “Mars & Venus” thing has some substance.

Theories About Swans

I’ve written articles here that touched on art theory, quantum theory, science fiction theory and number theory. There are many more theories: gravitational, electromagnetic, economic, social. Of course, there is also pure, practical and applied theory.

The idea gets around. On the outskirts there are theories about UFOs, ghosts, Noah’s Ark, many more!

And there are the “my theory” theories put forth from soap boxes, fliers and now blogs such as this. Literally such as this, since here’s my theory about theories.

CS101: Easy to Hard

It’s been said that programming is an exercise in managing complexity, and while that’s true, it’s only part of the picture. (Still, it’s a pretty big part!) More to the point, managing complexity applies to much more than software design. A defining characteristic of modern life is its complexity, so learning to manage it might be a Pretty Good Idea!

Thinking about a friend struggling with the complexity of life lead to remembering of one of P.J. Plauger‘s articles about problem modeling from his book, Programming On Purpose. (The book is a collection of his essays from the long-defunct, but most excellent, Computer Language magazine.)

Thinking about Plauger’s ideas again lead to thinking they might be worth sharing. Whether fresh or review, these ideas capture six key basic analytical techniques nicely. If you’ve never really thought about them before, you may find the ideas useful.
