Скачать или смотреть 2022 Chair Computer demonstrations

Since the topic was binary addition, I find it especially delightful that 11111 students showed up for the first session of Massey Math Mania on Tuesday (that's 31 students, for those who don't have children to explain it to you). Here they are, lined up in four rows of 7 to demonstrate as a Chair Computer. Each student is a single bit of a 7- or 8-bit value, where standing up is a 1 and sitting down is a zero. This was their very first task, I think -- adding 52 + 37.

For those who really want to follow along, the row of students closest to me at the beginning of the video is the sum, the next two rows are the inputs (37 and 52, respectively), and the row farthest from me are the carry bits. The ones column is closest to the camera (there's no carry-in bit) and the column closest to the projector screen is the 64s bit (except in the sum and carry rows, which also have a 128s bit).

The got it right in less than 100 seconds, so they're operating a 1 centi-Hertz. 8-D
