Sure. 1 Kings 7 (usually described as the "pi is exactly 3" text) describes a ring (the rim of a tub) with:
a thickness of a handbreadth (v. 26)
diameter from edge to edge of ten cubits (v. 23)
inner circumference of 30 cubits (v. 23)
Got that? Ok.
The inner-edge diameter is circumference/pi = 30/3.14... = 9.55... cubits
The difference between the ring's inner edge diameter and its outer edge diameter is thus about.45 cubits; to get the thickness of the ring we divide
by two (because the ring crosses the diameter twice), so.225 cubits, or about 4.05 inches, given an eighteen-inch cubit.
Note that a handbreadth is usually defined as about four inches, so we know the numbers add up; you can take it apart and get pi from it by working backwards:
The inner-edge diameter is equal to the outer-edge diameter minus (thickness * 2), thus 10cubits -.45 cubits(i.e., 2 handbreadths) = 9.55 cubits.
Their value of pi would be the inner-edge circumference (30 cubits) divided by the inner-edge diameter (9.55 cubits), thus about 3.14....
[The reading "pi is exactly three" is based on the weird idea of measuring the tub as a circle rather than a ring.] [and of course your mileage will vary based on the proportion of the cubit you use to your handbreadth, but let's gloss over that for now...]
Oh, I don't doubt that there are deficient registers out there... our coin rolls and miscellaneous nonsense go in the empty bill slots though, of which we actually have two.
Cash registers don't have a coin slot for dollar coins even though we've had dollar coins for decades. They should have them, but they don't.
Speak for your own registers... the cash register I work at has an extra coin slot past the quarters for the.50 and the $1 coins (they're not being given back as change, and there's never enough to make separating them a nuisance, so there's no problem mixing them).
The guy that came to install my [Comcast] cable modem ran this sequence:
log into XP under the first account on the list (an old roommate's)
drag an Internet Explorer shortcut to the desktop
set the IE homepage to http://www.comcast.net/
attempt to fiddle with network settings before realizing he's not on an administrator account
log in with the proper user account
...drag an IE shortcut to the desktop
...set the IE homepage to http://www.comcast.net/
...
Etc.
Of course I use Opera, so all that effort was wasted... He didn't try to install anything, though.
He was also rather nonplussed when testing the account to discover the auto-assigned password didn't work, and went out of his way to be surprised that I had already changed it.
It's not entirely absurd to require braille on drive-up ATMs. Last weekend I found myself driving behind a large red van with its rear window painted over (with an American flag, of course) and a full-width bumper sticker saying "A BLIND LADY IS DRIVING THIS VAN."
So...I'm sure it'd be useful for her.
(And anyway, even if the blind person has someone driving for them, shouldnt they be able to punch in their PIN on their own?)
