What is more iconic & associated with Sir Isaac Newton, a falling apple or glass prism? One reminds us his work on gravity held sway for centuries until Einstein’s Theory of Relativity. The other informs us of his discovery that white sunlight is made up of a rainbow of colours.
These simple devices still anchor basic physics lab experiments but have found new, unrelated uses as gifts and trade show promotional items.
What item from the past still used today is tomorrow’s millennial antique? A paperweight surely. Closed windows & air conditioning keep loose leaf from taking flight but for some that neatly stacked paper still says : “things to do”.
When is the last time you needed a ruler? Probably the last time you had to use a pencil to draw a straight line. But, if metric still has you baffled & your Internet connection is dead, maybe this will help you relate to inches.
Of course, there is nothing to say you can’t just put your glass prisms on window shelves & watch rainbows warm up your room while tracking the sun’s daily passage.
