Probability

I am a very mathematical person, and I often view life as a probability distribution. Each event has a certain probability associated with it, and the lower the probability the less chance there is that it will happen. For instance, the probability of a meteor coming to strike me out of the sky is so small that it is almost zero, and I can say with relative certainty that I will not be struck by a meteor today. However, the chance that I eat a bagel today is relatively high, since I have eaten a bagel at school for the past 3 years. Therefore, I can be fairly certain that I will eat a bagel today. However, sometimes something happens that reminds us that even if the probability is extremely small, it can still happen.

At the beginning of last summer, my family and I traveled to Paris for a family vacation. At the same time, I knew that a group of kids from my grade were traveling on a school trip to Paris the same week. However, the dates only overlapped for two days, and since the kids on the trip did not have cell phones or Internet access, there was no way for me to know where the other Uni kids would be, and Paris is a pretty big city.

However, the universe decided to go against probability. On the second to last day of my trip, our family decided to go to some museum that was about a 20 minute walk from our hotel room. We set off, but about 5 minutes into the walk it began to rain, so we took refuge in an old church nearby and admired the stained glass in the church. We stayed there for about 30 minutes before we decided to continue on to the museum. We didn't want to use the subway because we were running out of metro tickets and didn't want to buy more. When we were about 2 minutes away from the museum, we decided we were feeling a bit hungry, so we looked around for a place to eat. We saw a decent looking restaurant about a block off the road we were traveling on, so we decided to go there for lunch. At the same time, the Uni kids, just arrived in Paris, were emerging from a subway because they had to wait before their rooms were ready. They saw me with my family, and called me over, where we chatted fora bout 10 minutes before I went off to my lunch. The chances that we would run into each other on this random street in Paris are exponentially small. A million factors could have prevented the meeting; if it hadn't rained, if we had decided to use the subway, if we didn't go get lunch, and countless others.

Now it was a pleasant surprise that we saw them once, but I had serious doubts that we would see them again. But the universe thought otherwise. The morning I was supposed to go home, my plane happened to be delayed by 5 hours, but we didn't find out until we were already awake and eating breakfast. Since I had nothing else to do, I decided to go walk in the Luxembourg gardens, since they were less than a 5 minute walk from my hotel room. I was walking around the gardens when I noticed that somebody sitting on one of the benches looked familiar. I then realized that it was Mr. Garvey, and that meant that the rest of the Uni students were around the gardens somewhere. The Uni students had happened to go to the Luxembourg gardens at the exact same time I did. Once again, the odds against this were huge, but it still happened, not once, but twice. So even though everything can be assigned a probability, there is always a chance, no matter how small, that any event may come to pass.

  1. Wow, what are the odds of that? Though I'll be honest, we uni students, stole the idea of going to Luxembourg from you and your family. You had mentioned going the day before and all of us sitting in our youth hostile thought it would be just the perfect thing to do the next day. It was so cool to see a familiar face even if just for a few minutes. Strangely enough, you were not the only person we encountered on the trip that we knew. Lucie told me that there was a boy from her hold school that she had been good friends with that we ran into in Biarritz! At times like these it's amazing how small the world really is.
    Thanks for sharing!

  2. It's interesting that you often think of life as probability. Do you think that it's similar to predicting the future or more like expectations? I don't usually associate my daily life with math or probability (partially because I am not a big fan of probability). I do check the weather forecasts/predictions however. Otherwise, I usually don't plan ahead or try to predict the future.

  3. This is so weird and incredibly unlikely, yet somehow unsurprising. People from the same small town randomly meeting on the other side of the world, it kind of puts a new perspective on everything. Maybe we unknowingly speak telepathically.

  4. I think that if the universe could boil down to only numbers and mathematics, it would be incredibly boring. Imagine if you could predict every event in the world through statistics or other means. Reminds me of the TV show NUMB3RS where the main character uses statistics to solve crimes.

  5. That's such a weird coincidence! I agree with Maia, though, these weird things do happen a lot more than you would expect. When I was in fourth grade, we found the family of a friend of mine flying on the plane home from Arizona with us. They also just happened to be sitting in the row behind us.

  6. Probability just makes me think of stats (Bleh) and according to my insane calculations the probability was quite low!
