Calculators and computer algebra systems have become my drug of choice. Math too.
I do math the way some of our brothers and sisters smoke crack.
It's my current disease. I feel great at times while studying and solving problems, and at other times, I do not feel well at all, almost "sick" .... It's the nature of how we are wired, I suppose.
I also remember taking a C++ course at the local community college after I had lost my job with the State Park Service (for eluding the police on the way home from a bar in the midst of some kind of psychotic episode).
Anyhow, I am still to this day using a Fraction class I started back in 1998 during that class. Cool, huh? It is of course more sophisticated now, and I keep adding things to it like it is some kind of living thing. I mean, it's dynamic ... I think the teacher would be pleased to know that, even though I may not have done anything professionally with what I learned, after studying some programming. my love for mathematics was reawakened, and this has stayed with me. It consoles me during this otherwise uneventful life.
The thing is, I find this is as close to "being spiritual" as I can get these days. I honor those Beginnings by recognizing that I am still partial to rational numbers, and I like to include my little Fraction class in various programs.
I had found a program in C which found the inverse of a matrix using minors, a cofactor matrix, and its transpose. It did not take too long to transform it to use my own styled vector< vector< Fraction > >, which is simply a vector of vectors of Fractions.
I like to see the results and each step in fraction form since I want to be able to see the row operations and all that shiit.
It may not sound very "spiritual," but for me, it keeps me humble seeing as I know much more than I used to and I still know so very little. Life is a real kick in the teeth that way, you know?
The older I get, even as I understand more, I have a better feel for how little I know and how little I will ever really know.
In a sense, I don't mind becoming depressed. I think that when I am depressed, I am just more in tune with the nature of our lives. There doesn't seem to be a point.
If you learn to observe your own inner processes, you may begin to notice patterns, and so - if, like me, you become more depressed at night, it won't be a big dramatic ordeal. I just take that as a given.
