Some believe Stonehenge to be an ancient eclipse calculator. The number of blue stones and Aubrey holes are a clue

The stones may also represent scale models of mother earth and the moon

Lightning Calculator of Grand Rapids, Michigan (1900-1925).

No, they don't make singles like this anymore!
Cassette single of "Pocket Calculator" by Kraftwerk released 1981. The cardboard box has a flip lid just like a cigarette box. This was found in an old suit case containing cassettes belonging to Flickr Widow.
The mechanical calculator was manufactured and sold from 1948 until 1970. Electronical calculators and computers have put an end to mechanical calculators in the 1970s.

Sharp ELSI MATE EL-862
This calculator was given to me by my father when I was 6 years old (1986).
My younger sister also recieved one at the time. I looked after it and it is still working to this day.

The 17th century French polymath, Blaise Pascal (1623-1662), is famous for several reasons. Taught by his father, he was a child prodigy who excelled in mathematics and the science of his day.
Amazingly enough, whilst still in his teens, he developed ideas about calculating machines and over three years produced 50 prototypes. He is rightly considered one of the fathers of mechanical calculators and his findings contributed eventually to the rise of modern computers. In fact one of the early computer programming languages was named after him: Pascal.
His major scientific discoveries, however, related to chemistry, particularly the study of fluids and the clarification of theories about gases under pressure and the vacuum. I can recall first learning about him in high school Chemistry - a Pascal is now a unit of pressure.
His major contributions to mathematics began when he was just 16, both in geometry and probability theory. In fact this latter theory led him to his primary reason for choosing to believe in God (though let me add, this is NOT why he believed in God - more of that in the next picture).
Pascal's Wager is another term that has entered our lexicon. In it Pascal argues that one must stake one's own life on the outcome of a coin toss.
Suppose the following (and I'll use terms current with the theology of his age):
You believe in God AND
{God exists} = Eternal Happiness or Heaven
{God does not exist} = Nothing
You do not believe in God AND
{God exists} = Eternal Damnation or Hell
{God does not exist} = Nothing
Now leaving aside the debate about Hell (in which most people in Pascal's age believed), you can see the conclusion. By staking your life on the fact that God exists you cannot lose the bet. And more than this, you have lived a virtuous life (supposing that you are true to the principles of your faith).
But this rational argument is not why Blaise Pascal believed in God. He also said, "The heart has its reasons which reason cannot tell." So to the next picture...
The We're Here! gang is pulling our our calculators today. This one is built in to an old pocketbook of mine that had lots of spaces for credit cards, and even a place for your cheques to live. Of course we hardly use cheques any more. It's strange to look at an item that you used to use every day, a few short years ago, and realize that it's very much outdated.
This is a exposure calculator and exposure meter.
The meter no longer works, but is a nice example as a display pice for the collection.
This is a series 5 Burroughs Calculator with the case removed. It's essentially a mechanical adding machine: the numbered wheels rotate as numbers are added up. It is also capable of subtracting and multiplying, but doing so is cumbersome and time consuming. Nonetheless, it's a lot of fun to add stuff up with it.

HP 9810 Calculator (1974) This is really god old US craftsmanship. Everything made of steel and the CPU build up on 4 boards full of High Speed Schottky TTL ICs
I tried to resurrect it this afternoon. The battery is not the only problem, ... Next try is to open it. This was my first programmable calculator, bought around 1982.
De Rechenmaschine wurde 1784 von Johann Helfrich Müller (1746 - 1830) geschaffen. Der Darmstädter Oberbaudirektor Müller entwarf nach dem Vorbild ähnlicher Maschinen von Philipp Matthäus Hahn eine Rechenmaschine, die die vier Grundrechenarten ausführen konnte. Sie wurde vom Erbprinzen Ludwig, dem späteren Großherzog von Hessen-Darmstadt, 1791 für seine Sammlung angekauft.

This was in an exhibit of older technology at the Albuquerque Museum in Albuquerque, New Mexico. My mother had the one on the left -- I was surprised when I saw it sitting under glass in a museum. Using a stylus, one could add, subtract and multiply. I used to love fiddling with it when I was in grade school. Amazing to see how far we have come since.
