Floating Point Arithmetic
I am going to review a little bit the idea of floating point arithmetic, these ideas can be found in any elementary textbook on Numerical Analysis, or Knuth’s The Art of Computer Programming Volume II. When necessary I will introduce algorithms if I find them relevant…
OK, so the basic idea behind floating point [...]

Numerology and DNA…
This is a really short post that is a random thought I had while discussing genetics with a friend over dinner. Here’s the idea: DNA has 4 nucleotides that pair up thus as AT and CG. Now, there are 4 possible nucleotides, so lets use modular arithmetic (yep ).
If we randomly pick one of the [...]

I’m not dead (yet)!
Alright, I know it’s been a while since I’ve last posted, so let me get everyone up to date. The school year has started and I’m taking a number of advanced math courses, which of course requires a lot of math proofs.
I’ve always approached math proofs as a sort of “construction” exercise…like masonry for the [...]

If I’m not back in a week, avenge my death!
I’m leaving town for a week, so no one get worried over my absence.
I also wanted to quickly announce my programming blog “Object Oriented Kool Aid“. So far I am writing about my analysis of file systems and virtual file systems. I might include “How-tos” on programming file systems and/or virtual file systems. I have [...]

Time to provoke thought or die trying!
OK, so we know that vectors are rank 1 tensors and have a direction and magnitude…sort of like the wind blows 30 miles per hour (a magnitude!) due East (a direction!). A scalar is a rank 0 tensor…sort of like how at a particular point it is 56 degrees Kelvin (a magnitude!).
Now, following this line [...]

American Pi: it’s 3 by the will of “God”
I thought it was funny, someone remembered the Bible (i.e. infallible source of all truth and knowledge on Earth) mentions that pi is exactly three.
So why aren’t Christian fascists demanding this be taught in school? Pi being 3.1415… is merely a theorem after all, it’s not really a law. We should teach alternative theorems, one’s [...]
