Numerical beauty (palindromic)

Yesterday while counting something, I realized that adding 9 to 5 five times, resulted in a numeric palindrome 05 14 23 32 41 50.  A palindrome is a word that can be read the same way forwards or backwards.  Today, when I glanced at the numbers I'd written down again, I wondered if it would work with another number.  Sure enough, it does. Just add 9...

00

01 10

02 11 20

03 12 21 30

04 13 22 31 40

05 14 23 32 41 50

06 15 24 33 42 51 60

07 16 25 34 43 52 51 70

08 17 26 35 44 53 62 71 80


09 18 27 36 45 54 63 72 81 90

Beyond that, there's multiple additional pattern layers within the set, and the pattern renews after the first series; thus, after 01 10, you have a second numeric palindrome:

19 28 37 46 55 64 73 82 91 

Again, this continues after the other sets.  Aren't numbers beautiful?  I am especially curious about what is special about the number 9 in these sorts of sequences.  


  I've played mental games with numbers since at least fifth grade when I learned to 'cast out nines' as a method of checking multiplication, division or addition problems.  (Another pattern that I realized years ago is that the square of any number is +1 of the product of the number before and after it.  Thus, 8x8=64, which is one more than 7x9.) Anyways, I have no idea whether there is any significance in this sort of thing or whether whoever else has found it has given it a name, but I haven't found it if there is a significance or if it does have a name!

learning of an Afro-Surinamese-Dutch-American inventor

  While researching a presentation on Suriname for my Turkish class, I came across "Jan Ernst Matzeliger" as a significant person of Suriname descent. But I'd never heard of him, even though he was important in the history of both the places I grew up.  

 He was the sort of person who apparently thrived on overcoming obstacles. As the son of a Dutch engineer and a Suriname slave, he eventually left Suriname to travel the world and then settle in America where he invented an 'uninventable' machine, the shoe-lasting machine.  His idea was so unbelievable and complex that a person actually came from the Patent Office to make sure it really worked.  


 By most measures, he would be considered one of the most important African-American inventors in history; by birth, he was Afro-Surinamer and Dutch; but he became a naturalized US citizen.  He was featured on a US stamp in 1991.  Read more about him here.

Muğla, university city and Mediterranean province

  During the recent national holiday, our family got the chance to travel to the city and province of Muğla.  We got to explore as tourists, but we were also looking at it as a place we might be able to work and live in sometime in the future.  So, the pictures below will be a sampling of tourism, road trip, and our explorations of both city and province.

  The people were hospitable and gracious, and it was nice to get to meet a good variety of Muğlalılar.  This is a gorgeous area; unfortunately, I couldn't take a picture of the most beautiful view because I saw it a couple hundred yards out from shore in Akyaka, looking back over the clear blue water against the green cliffs with a pleasing little Turkish town nestled on the shore.

Olive orchards were a frequent sight.
the area has lots of mountains, as well as lots of greenery

the University in Muğla, pretty campus and the staff that we met were very nice

Ice cream and parks were important parts of all of our lives,
but they especially helped the littlest members of our group enjoy the time.
