Alternative Lines Through Time

When Stephen asked me to do an update to Lines Through Time, I demurred. I want to check in on that one in 10-year increments. But I got to thinking about the reasoning I employed in laying out the meandering course of my life, and it occurred to me that I don't (necessarily) agree with myself on this thing. That is to say, Phil 2008 disagrees with Phil 2003. Of course, once that sort of thing starts going on, look out. Anything can happen. I may do an update after all when Phil 2009 decides that Phil 2008 was overly fond of the decade as a measuring increment, or that he was just plain lazy.
Anyway, Phil 2003 tracks us through 20 years of decisions that led him to be sitting in his bedroom, looking out the window one fine autumn morning and wondering how he came to be sitting there. At each stage, he shows how a different decision or happenstance would have resulted in a completely different outcome. The problem with this approach is that each of these changes would have only changed the probability of one thing happening vs. another. Nothing is really excluded.
All of which is to say that Phil 1983 could have followed a very different course than the one outlined, and still ended up right where Phil 2003 picked up the narrative. Let's see how that might work. Phil 2003 writes:
After I graduated from college in Kentucky in 1983, I decided to move to Denver to go to law school. Had I not decided to go to law school, I might not have moved to Denver.
This one starts out kind of mushy. I might not have moved to Denver, but then again I might have. I chose Denver in the Law School time line because I had always planned to the live here as an adult. Why would that have changed?
I dropped out of law school a couple of years before starting my master's. If I had stayed in law school, I would never have started my master's.
Well, this is just silly. My wife went to grad school after getting her law degree as did (I think) my co-blogger. One does not necessarily exclude the other.
Mike and I met in grad school in 1986. If either of us had decided not work on that particular degree at that particular time, we would have never met.
This one is harder to get around. Unless we met later on the job (which would not have been as likely if I went ahead with the law degree) it seems unlikely that I would have befriended Mike had I not been in that degree program at that time.
My friend Mike started working at U S WEST a few months before I did. If Mike had not taken a job at US WEST, I would never have learned about the job opening there and would not have applied for it.


Stephen
and I were chatting about probability the other night. The specific topic was
video poker, which I sometimes play virtually while doing other things (e.g.,
sitting on conference calls.) When I say I play virtually, I mean that
there is no real money involved. I play with fictional, electronic dollars,
but the games are (presumably) the same as they would be if real dollars were
at stake. That presumption is borne out by the fact that I generally loose.
Stephen opined that he would never play a game where the odds are stacked against
him, which is the case with any typical Las Vegas casino game. The one exception
might be Black Jack dealt from a one-deck shoe; the conventional wisdom is that
a sufficiently skilled card-counter can work the odds to his advantage in that
setting.
