So What Do They Mean By A "Hair"

[jh]

According to news reports:

As a result of the earthquake in Japan:

1. Friday's magnitude 8.9 earthquake in Japan shifted Earth on its axis and shortened the length of a day by a hair.

2. Data-crunchers had determined that the temblor's force moved parts of eastern Japan as much as 12 feet closer to North America, scientists said — and that Japan has shifted downward about two feet.

hair = a very small amount (not a scientific term).

A 'hair' is a 'small amount' A "Red C** Hair" is an even smaller amount.

A little red c*** hair measures between .003" and .005" in diameter, using a mitutoyo digital 0-1" micrometer.

Paul... that's only valid if you collect the sample personally. :devil:

She collected it for us ( a couple pervy machine tool tech students), but we were assured it was both genuine, and an average statistical sample :devil:

We were HOPING we could do the sample collection ourselves... but as it turned out, we were the wrong gender for her 8-)
Good sport though...
