Kuenzi and Sri confer before the lecture.
MATC students and teachers eagerly congregate for the last lecture in the Math Club series..
Anyone who missed the lecture can email
Sri to arrange to view the presentation.


Professor Kuenzi discusses and compares numbers in binary and decimal form . Then he shows how the binary representations can be done by grouping colored disks.

He demonstrates a binary card trick.

He gave everyone a packet about his lecture that we could follow. He then started talking about binary numbers. He first taught everyone how to count in binary, then made us do so. Professor Kuenzi told us about Ethiopian multiplication and showed us how it was related to binary numbers. Then he showed us how the cereal box mind reading game worked because of the knowledge of binary numbers. He showed us how to count up to 1023 on our fingers in binary but told us to be careful with the numbers 4, 128, and 132. The lecture that Professor Kuenzi held was overall pretty interesting.

To: rgarcia@execpc.com Subject: The Binary Curiousities Lecture Date: Thu, 3 May 2001 15:05:31 0500 Hi Mr. Garcia, I attended the lecture on Binary Curiosities along with my husband. I had invited him to attend along with me because he also enjoys math puzzles. I thought Prof. Kuenzi was very interesting. How fun it must be to have a grandpa that so excited about math. His enthusiasm is evident. Prof. Kuenzi made the binary system easy to follow. I wish he would of talked more about adding, subtracting, multiplying and dividing Binary numbers. It was interesting the small amount you had us do for the 10 point assignment. It was also very interesting to learn about Ethiopian Multiplication, how it relates to the Binary System and how long the concept has been is use. Once the concept is explained, it's very basic and logical. The Cereal box mind reading cards and the game of Nim, again take puzzling games and make very simple ways of figuring them out because they are based on Binary numbers. My husband and I practiced counting in Binary on our fingers. It was a lot of fun, hard to get our fingers to do what we wanted them to do. Marian Villand

(Trigonometry) Date: Sun, 6 May 2001 21:53:35 EDT Subject: re: Lecture Report extra credit To: rgarcia@execpc.com The lecture at MATC about Binary numbers, by Professor Norbert Kuenzi, was an interesting and fascinating subject. Professor Kuenzi explained how the Ethiopian multiplication works, the cereal box mind reading cards, and the counting over one thousand on your hands system. The Ethiopian multiplication starts out by first: knowing how to double, how to half, and how to add. For example, 85X42+ 170+680+2720=3570. Although he explained how the technique works, I had a hard time understanding this concept. Next was the Cereal box mind
reading cards. This is a game in which you can have up to 5 cards.
On each card there are four numbers across, and four numbers down the card,
in addition, the numbers must be whole numbers from 131. I'm not
quite sure when the game ends or who determines the winner. When
he first started the game I had a hard time following the game. The
And last but not least, the counting to over one thousand on your hands system. By using ten of our fingers and binary representation, we should be able to count from 1 to 1023 on all ten fingers. This was a very funny game because I got lost at counting up to 20. It was quite hard trying to form up the correct fingers. I enjoyed the presentation
by Professor Kuenzi. I'm already teaching my husband the counting
over 1000 on your hands system. It's funny how useful
