Most people around here are far too young to remember Sputnik. (I remember Apollo 11!) But lots of the inventions people would mention as made in their own life time, are not - they are much older.

Like the microwave: As a boy, I read about these in my parents' old science books dated 1951 and 1952. These books also explained how color TV was made, with a photo of a color TV screen. And of optical "fibers" - they were glass pipes, not fibers, but the principle explained in the article is that of optical fibers. The first IC came in 1949. The first digital computers were developed during WW2. FM radio was patented in 1935, the field-effect transistor in 1925.

Of my own "firsts" worth mentioning that I did play around programming APL on what I believe was the first commercial portable (/luggable) personal computer, the IBM 5100, back in 1975 - but it wasn't an "invention", just a smaller form factor.

Some times I have fun with my younger colleagues, when a crash leads to a core dump, I ask if they have ever seen a real core dump - and then I show them my old 1152 bit core memory. Or I dig up my old card decks, or punched paper tape. Even flapping floppies, 8 in size, is something new and unknown to younger people today.

Now that you mention calculators: The first generation came as four-function (+-/*) or five-function (with square root as well) variants - the latter quite a lot more expensive. A friend of mine wanted to save money by buying the cheaper one, hoping that it actually could do sqrt, if you found the solder connections for the button. He digged out a scalpel to cut an opening in the plastic case where the 5-fn model had its sqrt button ... and the button popped up! Even the button itself was there, inside the case! No soldering required, no button needed. Making an opening in the case was all that was required.
