The note I am posting has been posted before (circulation finds). However, after seeing this thread: https://www.cointalk.com/threads/1963-k-series-note.364420/ which discusses interpreted "meanings" of the numbers and letters on a note, I had a thread idea. I would like to see notes you have found that have special meaning *to you* or otherwise interesting coincidences, even if they are not necessarily "fancy serial numbers". The note I have is my "Engineer's Note" or "Kilobyte Note". I can glean all sorts of made up meaning from it which only adds value to me, personally. Serial Number: 1024 is the number of bytes in a kilobyte, which is neat to me. District Letter: K of course is for Kilobyte! District Numbers: 11. Take 11 bits. 00000000000. Flip the 11th position. 10000000000. In binary, that translates to the decimal number 1024! 1024 is a perfect power of two. There are only so many serial numbers with this property. 1, 2, 4, 8, 16, 32, 64, 128, 512, 1024, etc. Let's see some notes in which you have found special meaning!
I think your note is special due to being a low serial number. As a point of interest, the note is also considered to be a Kennedy dollar, as it was Dallas, and K for Kennedy, and 11 was November, when he was assassinated. I found a $20 note the other day with 1776 at the end, but unfortunately just mixed numbers before it.
ZoidMeister, I love the last one, even though I always have to point out that electrical engineers screw it up using "j" because "i" is already reserved (current as a function of time).
Haha. My math teacher always had the top mug on his desk. For the bottom one, it's been a while since I've dealt with sigma notation, but it helped jog the memory.
Sorry for the derail @Blasty . It's sometimes difficulty to get past engineering jokes. I work with an office full of them, but I've never driven a train . . . . . . Back to the currency discussions . . . . . .
