One thing that makes thirty-six interesting is that it's both a square number and a triangular number - a square triangular number. Square numbers include (of course) 1*1 = 1, 2*2 = 4, 3*3 = 9, etc. Triangular numbers include 1, 1 + 2 = 3, 1 + 2 + 3 = 6, etc. Thirty-six is equal to 6*6 and it's also equal to 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8. Square triangular number.
I learned that bit of trivia as a child and for whatever reason it popped into my head shortly after midnight on my 36th birthday last week (although to be honest I had to use Google for help because I had forgotten the term "triangular number," even though the concept was in my head).
There are infinitely many square triangular numbers, so 36 isn't unique in that sense, but it occurred to me that because the previous number in the sequence is 1, and the next is 1225, 36 is the only square triangular number that can be the age in years of a person who is capable of comprehending and appreciating the fact that their age in years is a square triangular number. Interesting? Well, to me, anyway!
Of course, that's not the main reason 36 is an interesting number for me.
I'm sure a lot of people can relate to feeling a certain way when their age reaches that at which someone close to them died. A parent, perhaps, or perhaps a sibling or a close friend. And for me, it is undoubtedly surreal that my age in years is now the same as the age at which my wife died.
I'm currently reading a sci-fi short story anthology edited by Isaac Asimov called Where Do We Go From Here? Published in 1971, the book includes stories from the previous few decades, and each story is accompanied by a short discussion by Asimov of the scientific concepts in the story as well as some suggested thought exercises and study topics for intellectually curious readers. A very interesting book.
The first story, "A Martian Odyssey" by Stanley G. Weinbaum, was published in 1934 and is about the first manned mission to Mars, which the story envisions taking place in the 21st century (but amusingly only ten years after the first man reached the Moon, in the story's timeline). In the story, intelligent alien creatures are encountered on Mars, along with an alien artifact, a "little crystal" that gave off light that "destroyed diseased tissue and left healthy tissue unharmed."
The story closes as follows:
"I should like to see," he murmured.
"Yeah," said Harrison. "And the wart cure. Too bad you missed that; it might be the cancer cure they've been hunting for a century and a half."
"Oh, that!" muttered Jarvis gloomily. "That's what started the fight!" He drew a glistening object from his pocket.
"Here it is."
And so our protagonist has absconded with a potential cure for cancer.
I chuckled to myself at this ending.
I was stunned when I read Asimov's words on the next page:
It was the first published science fiction story of Stanley G. Weinbaum who, at one bound, became the most popular author in the field. It was not just the realism of his alien other-world creatures, but it was also his light and easy style, a far cry from the creakiness of the writing of most of the s.f. authors of the early thirties. For two years, he retained his popularity and then, as suddenly as he came, he vanished, for in 1936, at the age of thirty-six, he died of cancer.
This was a few days before my birthday. I was already thinking of the deeply personal significance of my turning thirty-six. The age at which my wife died, of cancer. So to read those words, after reading that story? Very surreal indeed.
This might seem like a mopey post. It's not meant to be. All in all, I feel pretty good about where my life is right now. And I don't mind being thirty-six. I just find it interesting to think about and make note of things like this. They help give life flavor.
Incidentally, in Asimov's discussion of another story in the book, he discusses some odd coincidences, including a story featuring an ichthyologist named Vernon Brock that was read by a real ichthyologist named Vernon Brock who "promptly wrote to" the story's author. Asimov concludes:
Such coincidences abound everywhere. What do you think of them? Suppose I said, "No matter how weird such coincidences may seem, it would be far more weird to have no such coincidences." Would you agree? There is a branch of mathematics called probability that deals with such things among others, if you are interested.
