Can I Sign Presentation

- Good afternoon, ladies and gentlemen. Thank you for coming. We're looking for the lost symbol, but it was on his slice of pizza, and he ate it. It's gone. I tried to get Dan Brown to come, but he couldn't make it. Albrecht Durer is kinda dead from 1500s, so he couldn't make it. Time machine's a little broken. Benjamin Franklin couldn't make it either, so you're stuck with me, so here I am. What I'd like to do with you is just to show you a few places where this gentleman, Dan Brown, got his ideas for this novel, and how he kinda put it all together. Hopefully, it will stimulate you, and you will do some research on your own, okay? There's a few games in here that are fun to play. First, let me introduce you to Albrecht Durer. Albrecht Durer was a gentleman, I assume he was, let's see, who lived in Germany in the early 1500s. He was a very exciting person. His father, also named Albrecht Durer, came from Hungary. Their original name was, I believe, Djilt, something like that, which means door in Hungarian. When they moved to Germany, he translated it into Tur, which is door, and eventually, it came Durer, which means door. It's Albert Door, there you go. Now, this guy was a genius. He was a philosopher, a mathematician, a sculptor, a painter, you name it, he did it. You name it, he did it. One of the things that he did was, he made this wood carving, Melancholia. That's right here. You can read all about it if you want to go on the internet and read it. What you see, it's a comment on art, and technology, and you see, there's an artist here. He's got all the tools around, and she, I believe, is very melancholy because, even though you have all these tools and stuff, creativity doesn't always come to you, you see. So there's a kind of sadness to this picture, but what's of interest to us and to Dan Brown was this little piece back here. This little piece back there is, it's a magic square. Let's see if I can find it. This is a magic square. It's a four by four magic square. You see it has four rows and four columns. Let me explain to you what a magic square is. A magic square is an arrangement of numbers so that each row, each column, and each main diagonal has the same sum. When all the numbers are added, has the same sum. The value of the sum is always equal to m times m squared plus one over two so that, in his case, a four by four square, the sum is equal to four times four times four, is 16, plus one over two, so you see that, in his case, the sum is equal to, 17 times two, is equal to 34. If you add each...
