About this website
This is David from
mathematicalmystreytour.blogspot.com.
I have had a small stroke – which has
reminded me that we only have a finite amount of time on this earth. Over the last few years I have discovered
and worked on an interesting group of numbers that I call sequence
numbers. I want to put this knowledge
on the web before I have a setback that would keep me from sharing it with
you – like maybe another stroke.
I call these numbers “sequence numbers” because
they produce a digital expansion that shows some known and recognized
sequence of numbers.
The first one I found was 998,001. I found this number in a post on a site
called “Futility Closet” operated by Greg Ross and his wife. The post noted that if you take this
number, form it’s inverse (1/998001), and then calculate it’s digital expansion
you will get a series of digits that appear to count from “000” to “997”, in
three digit strings, before it makes an error.
At first I thought this was either a hoax
or at least a big mistake. I checked
it out, did my own calculations, and found that it was correct. Then I started wondering if there might be
other number that would produce other known and recognized sequences.
That started me on a journey were I have
found many numbers that show this amazing property. I suspect there are an infinite number of
them. There are number that produce
counting sequences, multiplication sequences, power sequence, numbers that produce
combinatorial calculation, and numbers that produce Fibonacci like
sequences. And from time to time I am
finding new treasures to explore.
Phillip has agreed to help me put these
on the web so I can share them with you.
David
