I bought this Calculator Cheap on the internet ........when I recieved it the Numbers just don't add up !!
( Keyboard on calculator is 7cm x 7cm fullfilling MM requirements )
For this week's MM theme, I again, thought of an old friend who's been with me for decades. We spent a lot of nights solving endless problems together and she always got me through each one of them. Things have changed a lot since but I decided to keep her all these years. I'm sure someone out there might still have a slide rule hiding somewhere.
GROUP: MACRO MONDAYS
THEME: NUMBERS AND LETTERS
SUBJECT: A LOYAL CALCULATOR
(less than 2" horizontally)
This is a Macro Monday image - I don't often take part in MM, but couldn't resist this weeks theme "Evolution". What was required:
"Think now, before and after, yesterday and today...
Your photograph must include two (or more if you can fit them into a macro) objects that serve the same purpose but at different times.
In other words, show how something has changed, progressed or evolved over time either due to some event or just technological advancement".
So my image is of a vintage slide rule juxtaposed against my (brand new/ only got today!) iPhone 7 Plus running a Hewlett Packard 65 calculator app. The HP65 was the world's first programmable hand-held calculator, produced in 1974-1977 for a cost of $795USD (equivalent to around $4,000 in today's value). So I think i've captured "today" and "yesterday" with something in between as well for good measure.
The slide rule was my grandfather's - he was (like me) an engineer. In his day this was one of his tools of the trade. For me I have been a part of the evolution of calculations, with powerful hand-held devices that would have been unthinkably amazing for my grandfather (and would have saved him considerable time with calculations). The HP35 was the world's first hand-held calculator that could do scientific calculations (famously replacing the slide rule), which was followed by the HP65 only a few years later (first programmable). Now we have technology like the iPhone that enables us to pull up an app with a virtual keyboard of this historic technological marvel. I'd love to see the look on my grandfather's face if he could have seen that.
Oh, and just to carry on with the theme, my 'Macro Monday' image was taken with a vintage FD 100mm macro lens strapped to a modern DLSR.
Taken for 'Saturday Self Challenge': "Mechanical workings"
The inner workings of a mechanical calculator. Specifically this is a pinwheel mechanism from a Multo calculator, I think dating from the 1950s.

Here is one of my potential Macro Monday captures taken today for the theme this week that is "Back in the Day".
This was my grandfather's calculator he used for work and for doing taxes. Can add, subtract and multiply.
Captured here at f/32, ISO 100 for 30 seconds.
The numbers I entered into the mechanical machine is the 'date' around when these were made.
My contribution to Macro Mondays' challenge, "Pouch", on 14 Sep 2020. It's a well-used HP financial calculator, a relic from my pre-retirement past.
The Lightning Calculator Company of Grand Rapids, Michigan. Manufactured 1900-1925. (For a description: collection.maas.museum/object/372791)
This model belonged to and was well used by my grandfather. Stylus may not be original but has been with the machine since at least the late 1940s. Still works perfectly.

an infinite field full of cabbage
as far as my eye could see, a field of green.
I found this field in Broek op Langedijk (West - Friesland) Noord-Holland
a warm memorie of a nice summer.
Thanks for the texture my friend: lenabem-anna
"Nature hates calculators"

For WAH who are visiting calculators. I couldn't decide so you get both with this for the daily shot and the other for the 123.
The calculator that got me through engineering school some 40 years ago. Just like back then, it gives the right answer most of the time.
Father's mechanical calcuator. He was using it in bank. Today is nice reminder. With playing in PS I got this vintage look.
