My grandpa's 1950s slide rule beat my calculator app for quick estimates
Last month I was helping my nephew with his math homework and he pulled out his phone to check 8 times 47. I grabbed my grandpa's old Pickett slide rule from a box in the attic, the one he used for drafting at a steel plant outside Cleveland. I set the cursor and had the answer in under 10 seconds, plus it made him laugh at how goofy it looked. The thing is, that slide rule gives you a feel for the size of numbers, not just a blinking answer. I started using it for rough estimates on home projects, like how much lumber I need for a deck, and it's honestly faster than unlocking my phone. Has anyone else dug out a tool from the 50s that still does the job better than the modern version?
