Triangle of Nine by mathspassion on June 5th, 2018, 6:45 am
Triangle of Nine
We all know how great this number “9” is. It is remarkably known for its cyclic properties which results in beautiful mathematical patterns.
You might also know that,
The difference between a base-10 positive integer and the sum of its digits is a whole multiple of nine. Examples:
The sum of the digits of 41 is 5, and 41 − 5 = 36. The digital root of 36 is 3 + 6 = 9, which demonstrates that it is divisible by nine.
The sum of the digits of 35967930 is 3 + 5 + 9 + 6 + 7 + 9 + 3 + 0 = 42, and 35967930 − 42 = 35967888. The digital root of 35967888 is 3 + 5 + 9 + 6 + 7 + 8 + 8 + 8 = 54, 5 + 4 = 9.
Great!. OK lets come back to what I would like you to notice here.
Take any multiple of nine and write it same number of times as the co-factor of 9 is for that number, and add their digital roots, you will get exactly the same number.
Example. Here is a multiple of 9, 18 = 9 * 2 -> 2 is the co-factor of 9 for 18 -> Write 18 for 2 times and Add their d...

Library Books by zetreque on March 27th, 2018, 6:07 pm
My alma mater has decided to get rid of 8000 books from it's library. I find it incredibly sad that this happens because I know so many students half-arse their reports and don't make use of this wonderful database of knowledge. One of the criteria for getting rid of the book is if it hasn't been checked out in a while. I am shocked by some of the books being gotten rid of. The books are being donated to an organization that is just going to try to sell them online. The other sad thing is, no one seems interested in these books or there is a lack of communication of getting rid of the books.

I have been going in regularly and going through them all and allowed to take any I desire. This is difficult because there is so much good stuff but I will not have the time to read it all. There is also so much knowledge in books that you just can't find online!!!!

Today they were getting rid of a book that I had just used for one of my classes to write a report on. I saved it to at least give to...

famous quote by zetreque on January 26th, 2018, 1:48 pm
Give a man a fish and he will eat for a day, teach a man to fish and he will eat for a lifetime.

Well I just came up with a much needed addendum add-on to that famous quote.

Teach a man to fish and he will turn it into a for profit business eliminating your own food supply.

Rage by Asparagus on January 6th, 2018, 11:42 am
Stuck listening to the enraged ramblings of an involuntarily committed schizophrenic, though half his words are unintelligible, the self-righteous indignation comes through.

It occurs to me that righteous rage is a mood enhancer. Perhaps even the more sane of us (or more functionally insane) also will invent reasons to fume to lift ourselves up from pathetic obscurity to the ranks of the St George skewering demons with our profanities.
