For the other picture, can you make a drawing of how an algorithm works? I'll keep this on if you want to narrate it. Okay, I can narrate it. So, I feel like there is like a lesson. And then a serious of observations. And from those you have calculation. And then a determination. Okay, can you say a little more about what you mean by lesson? So, I feel like you have to with any kind of algorithm you have to inform it with some kind of hypothesis, I suppose. Okay. So that is what that is? Okay, cool. Where have you heard of this term before? A lesson? No, sorry. Algorithm. Oh, well I used to take computer science classes. I don't know, it's in the news all the time. Okay. Okay, cool. There's a lot of references to it in machine learning and things like that. Is that something you do? No. What do you do? I work in freight brokerage.
