#44 was A/C - Air Conditioning - an easy one for Milt, Jim, Peyton, Elaine, Joani, and Mike. And, back from missing from the Blog, Pete!
"All in Synch"
Another location that helped to fill my folder of "industrial" images was the Charles River Museum. Although not as many items to shoot, it did provide a different variety of machinery.
Here I zoomed in on the "teeth" of these circular drivers. The craftmanship required to keep these machines working was unbelievable. Not only did you have to have the gears interlock with each other but the designer had to carefully line up each of the drivers in order for the machine to work to its fullest capacity.
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.
A simple, inexpensive, yet powerful tool for calculation! One of the first devices to augment human intelligence as early as 2400 BC - it is a Latin word that translates into table or tablet.
The period 2700–2300 BC saw the first appearance of one introduced by the Sumerians.
Around 600 BC the Persians first began to use it.
Earliest archaeological evidence for the use of the Greek one dates to the 5th century BC.
Earliest known written documentation of the Chinese one dates to the 2nd century BC.
Around the world, #43 has been used in pre-schools and elementary schools as an aid in teaching the numeral system and arithmetic.
Paulg's Law. . .
it's not how much an item costs,
it's how much you save!
