Salary Survey Features New Format and Benefits
The 2004 edition of "The Engineering Income and Salary Survey" kicks off on
January 5, and NSPE needs your participation to ensure that the survey maintains
its reputation as a valuable resource. You can do so by going to
http://www.nspe.org and clicking on the
"Dollar Sign" icon, or going to
http://nspe.salaries.com on January 5. For the first time, a free
individualized report summary will be available to all participants in this
year's survey. The online questionnaire has also been reformatted to ensure it's
the fastest, easiest way to participate. NSPE asks you to encourage other
working engineers, regardless of membership status, to take the online survey.
Product of the Month: "Technically Speaking"
Compelling presentations are difficult to create, and technical presentations
are even more challenging. Written for scientific and technical professionals,
"Technically Speaking: A Guide for Communicating Complex Information" provides
insight into the process of conveying information, technical or not. It is
designed to lead you through the process of researching, organizing, and
presenting complex information and describes a timesaving 10-step approach for
preparing presentations. To order, visit
http://www.nspe.org/ps-home.asp
and enter Product #5900 in the search field, or call 800-417-0348. NSPE Member:

MATHCOUNTS PROBLEM OF THE WEEK
Can you solve this MATHCOUNTS problem? The answer will appear in next week's
edition of the Friday Update!
Taking a Good Look at 2004
How many distinct factors does 2004 have?
--------------------------------------------------------------------------------
What is the sum of the first 2004 positive integers?
--------------------------------------------------------------------------------
The sum of 2004 consecutive integers is 5010. What is the value of the smallest
integer in the list of consecutive integers?
Answer to last week's problem:
If we take 6,320,430 and divide it by 1450, we see that they are approximating
4359 digits per page!
--------------------------------------------------------------------------------
An increase of 2 million digits means that the old prime number (P1) had
4,320,430 digits. If we calculate the percent increase, we see that 2 million ÷
4,320,430 is a 46.29% increase. Now, we need to calculate 6,320,430 with a
46.29% increase. To do that we need to simplify (1.4629)(6,320,430) = 9,246,000
digits, to the nearest thousand digits.
--------------------------------------------------------------------------------
The general rule is that you would only need to check the integers through the
square root of the number. For example, if you were to check the number 16 to
see if it was prime, you would only have to check the numbers 1, 2, 3 and 4
since 4 is the square root, and if any integer greater than 4 was a factor, then
it’s matching-factor would have already been found when you checked 1 through 4.
For example, though 8 is a factor, it’s matching-factor is 2 and would have
already been found, thus showing that 16 is not prime. So for 211, the square
root is more than 14, but less than 15. So really, any factor greater than 14
would also have a matching-factor less than 14. Therefore, it would seem that we
would only have to check the integers 1 through 14. But notice that if 2 and 7
aren’t factors, there’s no need to check 14. Likewise, if 2 is not a factor,
then you would not have to check if 8 is a factor. The only integers you would
have to check in order to be certain 211 is prime are the six prime integers
less than the square root of 211, which are 2, 3, 5, 7, 11 and 13.
