Mysterious Properties of the Prince Ruperts Drop
Image Source: http://www.dickwhitney.net/

Prince Rupert's Drops (also known as Rupert's Balls or Dutch tears) are glass objects created by dripping molten glass into cold water. The glass cools into a tadpole-shaped droplet with a long, thin tail. The water rapidly cools the molten glass on the outside of the drop, while the inner portion of the drop remains significantly hotter. When the glass on the inside eventually cools, it contracts inside the already-solid outer part. This contraction sets up very large compressive stresses on the exterior, while the core of the drop is in a state of tensile stress. It can be said to be a kind of tempered glass.

The very high residual stress within the drop gives rise to unusual qualities, such as the ability to withstand a blow from a hammer on the bulbous end without breaking, while the drop will disintegrate explosively if the tail end is even slightly damaged. [

Many Magnificent Marble Machines

Today I paid a long overdue visit to one of my favorite spots on the internet: Woodgears.ca.

Woodgears.ca

Woodgears.ca is a woodworking site like none other. Its' tagline reads: An engineer's approach to woodworking. Every time I visit Matthias Wandel's contribution to making the internet a worthwhile diversion (better known as his web site) I come away with an urge to dust off the workbench and put on my thinking cap. Today was no exception.

Marble machines are a perfect example of engineering and woodworking crossing into the realm of artistic beauty. The featured article was "Seven amazing marble machines by Paul Grundbacher." In this post Matthias shares picture sent to him by Paul Grundbacher (from Thurgau, Swizerland.) Paul's creations are as impressive as they are entertaining...

Living Outside The Stacks

Pattern Mixing {In the Closet}

It was bound to happen, after months of watching other bloggers do it and do it well, I’ve finally mixed my patterns! I don’t know what took me so long, I guess it was nerves. We were always taught to never ever mix florals and plaids or stripes and dots.

 

Daenel - Full Length

 

But then we were also taught not to wear white after Labor Day and I threw that out the window years ago. So, you’d think I would’ve tossed this rule too. Maybe I’m a little bit more traditional than I like to think. shudder

 

Daenel - Detail

 

This pattern mixing worked for me because the main color of the cardi matched the accent colors in the tee. I don’t know if I could do pattern matching with mixed matched colors. Which is so odd for me considering my matching code goes something like this: “If you see the colors together in nature, you can wear them together on your body."

How could a stint of playing Lego possibly get any more fun? Oh, there's a way... It took us about 45 minutes to shoot this 150 frames of animation. Playback is 5 frames per second. Papaw directed from the camera position and Brodyn did the animation work. A fun introduction to animation. Enjoy!

Richesnay Time Again

Is This Richesnay
Photo by Nenad Saljic / National Geographic Photo Contest

It's that time of year again - the middle part of March (in this neck of the woods) - when those of my clan begin to anticipate and watch for the Richesnay.

I wrote a rather lengthy post several years ago entitled The Meaning of "Richesnay",  but in the interest of brevity I will simply refer you to that post and throw out the question: Have you ever heard of the word Richesnay or anything even remotely close that refers to a similar concept?

Richesnay [RIH-ches-nay] - The sudden blowing, swirling, voluminous, late winter snowfall that surely marks the coming of spring.

TLDR;
I am trying to track down the origins of the word/concept "Richesnay."

Ring any bells?

 


BlogDogIt Note: I had the image above, just knocking around; not exactly sure where it came from, but it has been among the random "Perfect Timing" widget images. I had always thought that I would use that picture to illustrate a Richesnay post but after compiling this post I really did not want to use it without attribution. So I ventured out onto the interwebs and promptly discovered www.tineye.com.; a reverse image search (in beta) that functioned masterfully. I therefore recommend that you give them a try the next time you are looking for an images source for attribution.
