RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

you have a hard time interpreting - or even care about - the
Roman numerals used to designate which
number in the Super Bowl series this Sunday's game represents, you're in good company. My guess is that most people
might be able to interpret a number like III as 3, or even XXXVIII as 38, but something like XLIX
(49 - this year's Super Bowl number) causes something like Excedrin headache number
XXIV to set in (see video below).

Even if you are are familiar with the Roman numeral system, did you realize that there is no character to represent
zero (0) or that negative Roman numerals do not exist, formally, either? Zero was considered sacrilegious back in
the day because it was considered an affront to a Creator who, it was reasoned, could never create nothing so there
was no need for a number to represent what didn't exist. Yeah, it's sort of circular reasoning. Some writers say
there is no zero because the Greeks and Romans, being manically efficient in mathematics, did not care to waste
a place holder in any decade column simply to hold nothing. Negative numbers never were received well by the haute
thinkers even though we now routinely equate subtraction with adding a negative number.
Table of Roman Numerals
One of the crazier rules of Roman numbers is that when you approach one number unit symbol less than the next
symbol, the lower symbol is placed to the left of the next higher place unit symbol to indicate a subtraction. For
example rather than writing 9 as VIIII, you write IX, or 10-1 = 9; XL is the same as 50-10 = 40. Hence XLIX is (50-10)
+ (10-1) = 40+9 = 49, et voila, Super Bowl 49.
If you don't really want to learn how to translate Roman numbers into standard form, you can always use one of
the many online converters, like this one from
Roman-Numerals.org. They have a lot
of other good info there about the counting system.
Enjoy the game... or at least the Carl's
Jr. and other such commercials.
