EXPONENTIAL BARBERSHOP RULER · BY VSAUCE
PRE-ORDER · SHIPS IN DECEMBERIt’s the world’s first ‘exponential barbershop ruler’ and while it may not be as big a deal as the invention of the pencil, we're incredibly proud of it. Our team noticed that a series of exponential curves could be devised so as to continuously and regularly grow apart. On a graph of such curves, there will always eventually be a transverse where each line is 1 cm away from the next. Then later on, they’ll eventually all be one INCH apart. And so on! In this way, every possible unit of distance can exist on a single ruler.
Even ad hoc units you may need when least expected (e.g. “how many of these paper-flowers-I-made is this sheet of construction paper long?”). Really big units (like light years) can only be partially represented, of course, but by placing the curves on a cylinder just right, we managed to make the whole device continuous.

A series of exponential curves could be devised so as to continuously and regularly grow apart make this ruler possible.

These are a few of our favorite useful conversions (and a few astronomical units thrown in for good measure) etched into aluminum.

To make sure you are a master of your new measurement device.
