Subject: [Phys-l] What's happening here?
Hi everyone,
After I finished working with a benchtop scroll saw, I noticed this
pattern in the sawdust on the work bench. The saw vibrates quite a bit,
so I'm pretty confident that the vibration is the root cause, but I
don't quite get why this apparent fractal pattern emerged. Ideas? http://imagecloset.com/tiny/874159
