Oh, Mike, this is wonderful. So this is the metric system as it applies to paper sizes. So there is a good deal of math involved, which I will spare you. But essentially, it means that you're dealing with fractions of a square metre of paper. And so you can bring your paper size into the metric system, which of course is a really handy way of unifying your weights and your volumes and your

lengths and widths and everything like that. So you have a sheet of paper which is slightly taller and skinnier than US letter, but which then turns into a really great system because you can fold it and it's in the same proportions as it originally was, just half the size, which you can't do with letter.

I think you can think about a notebook as being the nearest thing we had to a computer for hundreds of years. And then think of it as a bit of hardware. And then there's different kinds of software which you can put into it. So for instance, double entry bookkeeping, which every accountant or bookkeeper has to learn today.

And so a lot of your, you know, I ask everyone who's listening now to put up their hand if they've trained in double entry bookkeeping. And that changed the world, double entry bookkeeping.

So credits and debits and profit and loss and balance sheets and valuing a company, valuing a business, valuing stock, depreciation, all of these financial concepts entirely depend on writing stuff down, writing your numbers down in a careful format and then collecting them.

And the only way you could do that for hundreds of years was in a notebook. So everyone who is in any kind of business had to have notebooks, which they kept their financial records in. In 1300, back in Italy, this is when they started doing this. And It's at that point that we see the first companies. So if you've ever worked for a company, they were invented back then in Italy.
