Sorry Bill, I really didn't take note of the "metric conversions" at the
bottom, as we've all seen them so many times before.  Knowing the list
prefers ASCII, I simply converted accordingly.

PS My favorite remains 10^21 picolos = 1 gigolo  <g>

I suspect Nat Hager knew that, but trusted the rest of us to recognize,
as you did (and as I did), that they were exponents.

I pointed out, in USMA: 28341, that he could have preserved them in an
HTML-formatted email.

Unfortunately, email software does not typically allow one to format
characters as superscripts (Outlook 2000 certainly doesn't), so he would
have to have copied the existing HTML code (from the web site where he
found it) to a message set up for HTML formatting, rather than the plain
text message he used.

It shouldn't really be a big deal to us cognoscenti, though. <g>.

Andy Johnson emphasized that we should be sure look at the "metric
conversions" at the end of the Edmonton journal article. Some of them
are quite clever and funny. The first two however, were garbled
somewhere; I don't know if the Edmonton paper printed them that way or
whether the got garbled on the internet or on the email messages that
copied the article.

As I saw it in the original article submitted by Nat Hager and later
repeated and emphasized by Andy Johnson, the first two conversions read:

1,012 microphones = 1 megaphone

106 bicycles = two megacycles

Clearly these have been erroneously copied. Someone, through whose hands
this passed, knew little or nothing about scientific notation (powers of
ten), or perhaps knew that but didn't know how to type exponents.

The above two "conversions" should have been:

(10 to the 12th power) microphones = 1 megaphone 

(10 to the 6th power) bicycles = two megacycles

I have written out the powers of ten to avoid having the same problems
that my unknown predecessor had. the only way I know to reliably type
them in email (without using HTML or something) is to use the caret mark
(^) to indicate an exponent, so I would have had to write:

10^12 microphones = 1 megaphone

10^6 bicycles = 2 megacycles

It is interesting that, after the power of ten had been incorrectly
written in the first example, the error was compounded by adding a comma
to separate the thousands from the hundreds. That is:

10^12 erroneously became 1012 which then became 1,012

This clearly shows that, at some point, someone did not just mistype
something, but he or she really thought it was supposed to be one
thousand twelve instead of ten to the twelfth power.

At least there was only one error when 10^6 erroneously became 106.

By the way, there are many more of those humerous "conversions". There
is even a list in the college physics book I taught from over many
years.
