There are numerous candidates for the designation as “planet’s greatest invention.” The circular axle. The printing press. The combustion motor.
As per a recent publication, however, that title belongs to a mechanised timber mill conceived through Dutchman Cornelis Corneliszoon during 1593.
“Prior to automated sawing, building a modest trading ship necessitated around ten sawyers working for three months,” writes Jaime Dávila. “With wind-powered lumber mills, the same quantity of processed timber could be produced in less than seven days.”
Thanks to this rapid automated cutter, that turned logs to boards using almost no manual labor, the Dutch were able to construct ships more quickly than any other nation, which sparked one hundred years of Dutch maritime, financial and artistic dominance across Europe and the globe.
The inventor's lumber mill, argues the writer, represented “humanity’s initial authentic factory apparatus.” A wind turbine rotated a gear. One component transformed the rotary movement into up-and-down action to power the saw. A separate mechanism changed that same spinning movement into a lateral movement feeding the timber to the blade. A ratchet system moved the log ahead a measured step each stroke.
“Every component was simple by itself. Corneliszoon’s brilliance was to combine these parts so the machine operated in a perfectly controlled sequence, sawing on every descending stroke and moving on every return stroke. This constituted an astonishingly clever application of fundamental parts.”
A fact that brings us to the current puzzle. I’d like you to reimagine a key the fundamental concepts underpinning this historic invention.
Construct a machine which converts rotary movement to up-and-down motion. Your available these components exclusively: A spinning wheel. Two pins. Two bars. A “guide”, which is a tube or housing into which a single the rods will fit perfectly. (Consider that you can mount components on a stand, so that the components don’t collapse.)
I’ll be back later today UK time with the answer.
Meanwhile, NO SPOILERS. Rather, please propose (less celebrated) contenders as the planet’s most impactful invention.
