#5 - "Twin Shut-offs"

#6 was paper! Something running afoul with this blog as once again those outside of Massachusetts go to see it - Peyton, Mike, and Joani while our in-staters were closed out.

"Twin Shut-offs"

As I mentioned several entries ago, the Stone Mill had been stripped of much of its inner workings. I struggled to find items of interest to fill the time there. Over in the corner, near what once was the floor's only bathroom were these two shut-off valves - "the twins!"

Greatest Inventions of All Time!
Recently I came across an article about the greatest inventions as determined by a large group of scientists, philosophers, educators, and other professions. Their task was to create a list of "the Greatest Inventions of All Time." Conveniently, the final list numbered fifty! so, I'm starting with #50 and working my way down to Numero Uno in December.

Fear not as I will offer you some hints as to what the invention was.

#5

At Number Five: 
Refracting light through glass is one of those simple ideas that took a mysteriously long time to catch on. “The Romans had a glass industry, and there’s even a passage in Seneca about the optical effects of a glass bowl of water.”  But it was centuries before the invention of #5 dramatically raised the collective human IQ, and eventually led to the creation of the microscope and the telescope.

This week’s invention is a transmissive optical device that focuses or disperses a light beam by means of refraction.

This Top Ten Winner can be made from materials such as glass or plastic, and are ground and polished or molded to a desired shape.
