The Evolution of Calculations
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.
