Re: Objectionable Material for Children

I have just watched the _Unbreakable_ movie. It's *very* good.

But this is not what I want to say.

They did a good job of translating all horrible imperial units to
SI. Except once. They mention a runner that makes "400 yards
in 45 seconds". What the hell is that?

Well, I know that 1 foot = 28 cm (see previous message), and
1 yard = an integer but weird number of feet (or is a mile that
is an integer but weird number of yards? - oh, forget it).

So, lemme guess:

if 1 yard = 2 feet, then v = 5 m/s (hmmm.... too slow)
if 1 yard = 3 feet, then v = 7.5 m/s (hmmm... this seems to
be ok)
if 1 yard = 4 feet, then v = 9.956 m/s (hmmm.... for a 100m
spring this is a very fast speed, but I don't think anyone can
keep this speed for 45 seconds!)

So, 1 yard = 0.84 meters
