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.

The first decade of HP programmable calculator evolution. Hewlett Packard invented the world's first hand-held programmable calculator, the HP-65 in 1974. This was followed by the HP 20-series, of which the HP-29C was the most powerful and offered continuous memory in 1977. The HP-34 evolved in 1979 and offered numerical integration. In 1979, HP introduced the revolutionary 41C, which had alpha-numeric capabilities, as well as expandability through memory cartridges.
Hewlett Packard 67 clear case and normal production versions. The clear case enabled HP engineers to see the internals, as well as test case production techniques to ensure that imperfections (bubbles and the like) did not form in the case during the production process.
The HP67 was an improvement of the HP65, with more memory, more defined keys, and improved programming ability.
Hewlett Packard 65 - the world's first hand-held programmable calculator, made between 1974 and 1977. Original price was US$795!
It had a magnetic card reader to store programs.
From HP Virtual Museum:
The HP-65 was HP's fourth handheld electronic calculator and its third scientific calculator.
Nicknamed "Superstar," the HP-65 was the first magnetic card-programmable handheld calculator, which is why some call it the "world's first handheld computer." The HP-65 could read from and write to magnetic cards, allowing the user to buy program cards from HP or save programs on cards.
Although the HP-65 was similar to the HP-35, HP's first handheld scientific calculator, new features included a card reader, the slot to hold a card below the display and the second slider switch to select program or run modes. The HP-65 cost $795 when it was introduced.
HP produced the world's first programmable calculator in 1974 for a whopping $800!! It used magnetic card strips to record programs. It was very considered extremely powerful in its day.
A Blanknut Hewlett Packard 41CX with a rare clear cased bar code reader. The bar code reader was used to read programs in the form of a bar code - this was seen as an advancement over the magnetic cards that were used in earlier HP models (the HP65 and HP67).
The HP41CX Blanknuts were made by HP to be customisable for a specific purpose - typically they were purchased by companies and programmed with their own programs. They have a very plain keyboard layout with only the numbers and alpha keys displayed, with no scientific keys shown at all.
This 41CX has a standard overlay over the keyboard - without it it's difficult to know what the keys are for.
