December 23, 2007: Useful Tattoo

From Scienceblogs.







Quote: "My right forearm has a 8" ruler on it that I use for everything from measuring PVC diameter to wire lengths. My background is in embedded hardware design, but I choose to spend my time doing experimental building, transportation, and energy these days. The tattoo gets used daily."--Mikey

Fantastic tats in his series. The host also wrote an acalimed book about evolution.

very cool. Did you see the Origin of Species one from a Darwin sketch?



Thanks for posting.



You could get logarithmic scales done on each arm, and then use them together as a slide rule.



Metric system rulez!



I tried to guess what it was before clicking on the thread.

I failed.



Best I came up with was personal details on someone with a lifelong condition like a fatal allergy, diabetes or other So that if they pass out when they aren't with friends/ family, people will know what to do.



The ruler is way cooller though.

But damn you Bruce. Looking at those amazing tattoos has made me want another one. Just wow.



Somewhere on the internet, someone has that tattoo, is making a fist, and using the tat as a depth gauge.

Bruce's IotD "useful tattoo" is currently front-page at reddit.com. Well done xoB!



Is that why things were running so slowly tonight?



and in the less cerebral tattoo world....



Somewhere, I saw a picture of a ruler tattoo on a woman's inner thigh, but with the zero up at her crotch.



I know a guy who is into fisting who has one starting at his proximate knuckle and goes to his elbow.



This is reason #174 why Americans resist metrification. Or maybe his left arm is metric.
