problem solving

I am trying to make a kinetic photo for a contest, and it looks like I won't make the deadline.

.

[Correction: It's not a contest, it's an assignment.]

.

The camera must be moving for a kinetic photograph. I did not want to copy someone else's idea. Like when someone flips a compact camera in the air for a random exposure and try to catch it, lest it break. Or where the camera is attached to a moving car. My idea was to go for the effect of a space ship moving through a star field.

.

I made a contraption that would hold the toy one cubit from the camera. Then, aiming at white Christmas tree lights, I pan the camera for a blurred background, hoping to keep the ship in focus.

.

Instead of white streaks, I got colored dot patterns. I am not sure why. And what about that color?! Maybe the bluish led (fixed on the ship) offset the white balance.

.

I'm not sure how I want to solve this problem, but sometimes you have to think outside the box:

.

Here is a story about problem solving I found at Arcamax Publishing.

.

Many hundreds of years ago in a small Italian town, a merchant had the misfortune of owing a large sum of money to the moneylender. The moneylender, who was old and ugly, fancied the merchant's beautiful daughter so he proposed a bargain. He said he would forgo the merchant' debt if he could marry the merchant's daughter. Both the merchant and his daughter were horrified by the proposal. The cunning money lender suggested that they let providence decide the matter.

.

The moneylender told them that he would put a black pebble and a white pebble into an empty bag. The girl would then have to pick one pebble from the bag. If she picked the black pebble, she would become the moneylender's wife and her father's debt would be forgiven. If she picked the white pebble she need not marry him and her father's debt would still be forgiven. But if she refused to pick a pebble, her father would be thrown into jail.

.

They were standing on a pebble strewn path in the merchant's garden. As they talked, the moneylender bent over to pick up two pebbles. As he picked them up, the sharp-eyed girl noticed that he had picked up two black pebbles and put them into the bag. He then asked the girl to pick her pebble from the bag.

.

Now, imagine you were standing in the merchant's garden. What would you have done if you were the girl? If you had to advise her, what would you have told her? Careful analysis would produce three possibilities:

.

  1. The girl should refuse to take a pebble.
  2. The girl should show that there were two black pebbles in the bag and expose the moneylender as a cheat.
  3. The girl should pick a black pebble and sacrifice herself in order to save her father from his debt and imprisonment.

.

Take a moment to ponder over the story. The above story is used with the hope that it will make us appreciate the difference between lateral and logical thinking. The girl's dilemma cannot be solved with traditional logical thinking.

.

Think of the consequences if she chooses the logical answers.

What would you recommend the girl do?

.

The girl put her hand into the moneybag and drew out a pebble. Without looking at it, she fumbled and let it fall onto the pebble-strewn path where it immediately became lost among all the other pebbles.

.

"Oh, how clumsy of me," she said. "But never mind, if you look into the bag for the one that is left, you will be able to tell which pebble I picked."

.

Since the remaining pebble is black, it must be assumed that she had picked the white one. And since the moneylender dared not admit his dishonesty, the girl changed what seemed an impossible situation into an extremely advantageous one.

solving puzzles

Mysteries.

.

Secrets of the universe.

.

Some knowledge is not intended for man. Such as a lady's true weight or dress size, the contents of her purse and what ladies talk about when they all get up to go to the rest room.

.

On the other hand, some mysteries are meant to be discovered... like how to be a good husband and father. Mistakes abound, but I know more today than 20 years ago. And yet, 20 years ago, I had enough information to begin that journey. (Theologically, the doctrine of the trinity comes to mind.) Don't you wish you could get a Matrix download for instant knowledge and thorough understanding?

.

The Truth must dazzle gradually Or every man be blind---

-Emily Dickinson

.

One nice thing about blogging is that we give and receive information in digestible bits. If we each try to tell our whole story all at once, it would be overwhelming.

.

In life there are many puzzles, things that have not yet been fully revealed. Though not all knowable, many of these will be worked out one portion at a time. Just because we don't have full disclosure in the present, doesn't mean that it must be an unlockable secret. Maybe we need to work a little harder to figure it out. Maybe it will come together after we receive a clue or two.

.

NaNcY wrote a very brief piece yesterday pointing to "the One that gives the knowledge." And that's key, isn't it? Because if we don't have an accurate reference point, how can we have any confidence in what is true?

[For the record, I have never completely solved a Rubik's Cube; it was my younger son who put the yellow side together for me.]
