This week's theme for Macro Mondays is "Intended Contact"... and there is definitely intended contact when it comes to a predator and its prey! In this photo a Green Jumping Spider has captured and killed a Soldier Fly more than twice its size.
Otis King's Pocket Calculator ~~ By Jackie~~
1956 Otis King's Pocket Calculator ~~ Versus ~~ A modern plastic calculator. Created for Macro Mondays theme "Evolution"
This Otis King's Pocket Calculator dates from around 1956. This particular model is Model K, and is characterized by scale 414 on the bottom and scale 423 on the top.
The six-inch cylindrical slide rule consists of a chromium-plated holder, a metal cylinder that slides into the holder, and a black metal tube that fits around and slides up and down on the cylinder. The rule is ten inches long when extended and equivalent to a linear slide rule 66 feet in length. Two short white lines on the tube and a black mark on the chrome cap at the end of the cylinder serve as the indicator. A paper spiral logarithmic scale is attached to the top half of the holder. A second, linear and logarithmic, paper scale is attached to the cylinder. The logarithmic scales are used to multiply and divide, and the linear scale is used to find logarithms.
At the end of the cylinder is engraved Made in England and at the top of the cylinder is printed the patent number.
The calculator weighs about 210 grams, so you would have needed a good strong pocket to place it in.
Not knowing anything about this calculator, I Googled it and found an email address for a gentleman called Richard Lyon, who kindly provided me with some of the above information.
