Seeing through new eyes
Neither do the astronauts, those privileged enough to have looked down from orbit.

+Ron Garan shared an observation upon returning from the I.S.S. riding back aboard a Soyuz after the Shuttle was retired.
The capsule lands in Kazakhstan, half way around the world from where he lives.

Ron said the Soyuz rested on it's side, and through the window he could see soil and the grass growing in it and his first though was I am home

True, it's all a matter of perspective, and we each have our own.

A copy of Nature

Having taught myself rubber mold making to replicate my jewelry designs, the technique can be used to copy anything that can withstand the temperature and pressure of the vulcanizing process. 

Here is a close relative of Tridacna, the giant clam that made an excellent belt buckle.

Yes, it vulcanizes at room temperature. Generally no release agent is needed depending on the material you're casting with.

Magma movement provides seismic imagery of structure beneath volcano

Sound waves generated by earthquakes from magma movement travel through material and temperatures at different rates, yielding a detailed structural image.
 
First-ever 3D image created of the structure beneath Sierra Negra volcano | #Geology #GeologyPage

The Galápagos Islands are home to some of the most active volcanoes in the world, with more than 50 eruptions in the last 200 years. Yet until recently, scientists knew far more about the history of finches, tortoises, and iguanas than of the volcanoes on which these unusual fauna had evolved.

Now research out of the University of Rochester is providing a better picture of the subterranean plumbing system that feeds the Galápagos volcanoes, as well as a major difference with another Pacific Island chain -- the Hawaiian Islands. The findings have been published in the Journal of Geophysical Research: Solid Earth.

Ballast Stone

Geologically the Cayman Islands are little more than fossil coral with White beaches - So you can see a dark igneous stone like this from a hundred yards away.

On their way back to Spain, the great galleons Adjusted their ship's ballast according to their load. They did this by adding weight to the ship's bilge.
The trip back home took a while, and as it happened, the islands of the Caribbean were populated with turtles. Well, a turtle could survive in the bilge of the ship for months without food or water, providing the crew with fresh meat for the journey.
This stone was thrown overboard and it's weight replaced with a live turtle as the ship passed the Caymans.

 I felt the stone would make a nice memento of the scuba trip so I brought it home. looking closer as I cleaned it up, I noticed it was riddled with what looked like green crystals - So being a lapidary kind of guy, I slabbed it on my diamond saw.
Turns out it is full of little emeralds, The source of which in South America was a primary draw for the crown.
The white you see is from impacts rolling around in the surge from a couple of hundred years of hurricanes.

after polishing the cut and seeing it, coupled with the history behind it, I was compelled to make a display for it.
The tag says "Reef Gallery" which was my mail order business for  marine oriented jewelry.

Life at Escape Velocity

I applaud NASA and their effort to further engage the public in the operations of the greatest multinational effort of scientific research in history.

Credit must go to the Canadian rocket man, former station commander +Chris Hadfield for his outreach to social media and the world wide interest he generated.
Well done Commander!

NASA couldn't help but notice the potential for public relations.
 
Space history will be made tonight, and it will be broadcast "Live From Space" for the world to watch. How NASA and National Geographic will transport you up: http://oak.ctx.ly/r/sviu

The two-hour "Live From Space" special, which National Geographic Channel will air at 8 p.m. EDT/5 p.m. PDT (0000 GMT)

A global communications network

Is a catalyst for social evolution and Is a hallmark of an advanced civilization. If you are reading this, you are privileged enough to have access to it.

It occurred to me reading the link headline, that after the Barbary Wars It became the stated mission of the United States Navy to keep the world's oceans "Open and Free" for all. That's how important the flow of commerce was for the development of Nations.

An open and free network is just as critical

Story
Tagline
Pay no attention to the scars, life has been good to me
Introduction
Rabid about science - religion, not so much.
Astronomy - because everything else is a derivative.

Physics - because it describes how everything behaves.

Geology - From the moment that I looked down as a child and saw a colored rock...
 
Biology - because it defines the living World around me and explains what I am, why.

Metallurgy - I like casting precious metals, welding, forging, plasma cutting, I am a gold and silversmith, however I will follow anywhere inspiration leads.
Lapidary - I blame this on those colored rocks.

I have a strong mechanical aptitude. I was trained as an airframe / powerplant technician in the Navy, specialized in axial flow engines. 
I really enjoy fixing things, and creating manifest reality from an idea.
 
I have been a scuba diver since 1985. and the Caribbean is my old friend.

     
Bragging rights
I have more than any one man deserves. Married 35 years to the most beautiful woman I ever saw. Two great kids, and two Granddaughters. I ran the second fastest time ever recorded on the US Naval training base obstacle course San Diego Calif. Had the honor to serve aboard the USS Enterprise.
