Letters to Note

Sean Mitchell provides a thoughtful fresh look at the world every Friday.

Dear Note:

Notey, love, my fork broke today. Well, it didn’t break, it fell apart. It was slightly upsetting: I needed that fork to eat. But that’s not what I really wanted to talk about.

I was today called one dimensional. It’s not true. I mean I know I am a characterization, but I’m at least two dimensional. At least that’s how I always considered myself. I mean, I’m more than a person who merely eats bagels. I sometimes eat broccoli and I do do math on occasion. I have depth. Look.

Whether ’tis nobler in the mind to suffer \ The slings and arrows of outrageous fortune, \ Or to take arms against a sea of troubles, \ And by opposing end them?

See? That was deep. Look at the complexities I have: I ponder whether it’s better to be hit by projectiles or attack a troubled sea. Clearly, I’m at least three dimensional. Aren’t I, Note?

(heart)

Sean Mitchell will be posting every Friday with a fresh way of looking at the world.


Dear Note,

Remember my plan to remember things? How if only I could remember to remember I would be able to remember? And how my plan was to remember to remember? Well it didn’t work. Sure it sounds easy, all you need to do is to remember to remember to remember to remember. But it turns out for that, you need to remember to remember something that’s kind of hard to remember.

I HAVE FOUND A SOLUTION!

It’s totally simple (totally). Okay! You see if you look closely Note, you’ll see a pattern. I’m tring to “remember to (r o)” where r is some process of remembering and o be the memory for rememberance. So let’s notationalize the process by saying memorize = \r -> \o -> remember to (r o). I know what you’re thinking (I’m thinking it too) “how can I possibly think that”.

Well I found something to let us do this. It’s called a ‘Y-Combinator’. It used to find the fix point of our memory (which I think is the point where it’s memorized). It sounds fancy therefore it must work. So the Y Combinator (Y) is \f -> (\x -> f (x x)) (\x -> f (x x)) (Yes. Yes. I know, Note, that’s lazy. I don’t want to do all that memory work after all). Now, let’s remember = Y memorize.

Now I can remember everything! Well in theory. Whenever I try to “remember (wash the dishes)”, for some reason I just don’t seem able to think the whole thought through.

You are my sunshine,
Sean
