Just happy...

Yesterday, I sat down and sketched out the visuals for each single digit number that I use when remembering each number. All will be revealed in time. But for now, i simply changed the blog picture to reflect a green heart lying sideways to demonstrate 3.

Since it is the weekend, i figured that i am not going to write any new details about specific numbers. Thus, the question arises...what do i write about? Well, i decided to write about today's date! It is 25th of September, 2010. In letters only it can be written as 09252010 (U.S. style) and 25092010 (other styles). As you can note, there is a big difference between the two numbers if you consider them simply numbers rather than dates:

9,252,010

2,50,92,010

1st version: 9,252,010 translates to violet-lt. blue-black-lt. blue-white-red-white.
If you notice, i have written the number in the version that is most common in United States - commas before every 3 numbers (am I the only one who sees the craziness of three all around me??). Thus, we read the number as Nine million, Two hundred, Fifty-Two thousand, Ten.


2nd version: 2,50,92,010 translates to lt.blue-black-white-violet-lt.blue-white-red-white. This is a longer number and i have written it out in the style of writing numbers that i learned growing up...a comma before the last three numbers and consecutive commas before 2 digits thereafter. This number would be read as Two crores, Fifty lakhs, Ninety-Two thousand, Ten.

The bands i have shown above are the kind of bands that will help visual learners memorize numbers better. So let us try to find out what is unique (mathematically) about today's numbers - i am going to use the 1st version to begin with. The number is obviously an even number, and is divisible by 1, 2, 5, 10. After dividing by 10, it is easy to see that the result 925201 is an extremely odd number to play with. A website helped me find the other positive factors - 1, 2, 5, 10, 71, 83, 142, 157, 166, 314, 355, 415, 710, 785, 830, 1570, 5893, 11147, 11786, 13031, 22294, 26062, 29465, 55735, 58930, 65155, 111470, 130310, 925201, 1850402, 4626005, 9252010. Remember that the negative versions of all these numbers are also factors! Interestingly, the basic (upto three digits) prime factors of 9252010 are 1, 2, 5, 71, 83, 157. The spacing between 5 and 71 is big!! I guess what i am trying to accomplish here is to demonstrate how every number is special and unique, no matter how large it is!

For the 2nd version; 25092010 - again, even number divisible obviously by 1,2,5,10.  But beyond that, the number becomes more interesting than the first version of today's date. Upon finding factors (thank God for wonderful computing applications, it is easy to do!) we obtain 1, 2, 5, 10, 1013, 2026, 2477, 4954, 5065, 10130, 12385, 24770, 2509201, 5018402, 12546005, 25092010. Considering the prime factors in this case, we get a distance of 1008 between 5 and 1013 and the next prime number 2477 is 1464 spaces away from 1013!! Talk about large numbers, eh?

Anyways, my 3rd factor is about to wake up...so i will stop my number-mania for today...

Till tomorrow, or later...ADIOS!!
