Time: March 14, 2021, Sunday, 1:59 – 4:30 p.m.
Location: AB Ballroom
Registration link: https://duke.qualtrics.com/jfe/form/SV_bxOI9BpsxzLSzm6
Organization: Zu Chongzhi Center of Mathematics and Computational Science
Games List and Earning Credits:
| Name | Contents | Description | Points Calculations |
| Main Board | Recite π with longest digits.
|
First 300 digits will be displayed in the screen for remembering, and the participants should write down the numbers on the whiteboard to show their memory abilities.
One volunteer needed. |
First half: No. 1 would win 30 points, No. 2 would win 20 points, No. 3 would win 15 points.
Second half: No. 1 would win 25 points, No. 2 would win 15 points, No. 3 would win 10 points. People who write more than 100 digits would win a Poker – the fragrance of the formula. |
| Table 1 | Number Huarong Road, with two boards. | One-on-one PK.
Two volunteers needed.
|
20 points.
Winner would win a red stamp, and not allowed to participate again, loser would win a blue stamp, and if you reach the maximum of three, and will be not allowed to participate again. |
| Table 2 | Gravity Chess, with one board. | One-on-one PK.
Two volunteers needed. Two props available. |
15 points.
Winner would win a red stamp, and not allowed to participate again, loser would win a blue stamp, and if you reach the maximum of three, and will be not allowed to participate again. |
| Table 3 | Dots and Boxes, with two whiteboards. | One-on-one PK. One for 4 x 4 lattice, and the other for 6 x 4 lattice.
Two volunteers needed. One prop for each style available. |
6 x 4: 20 points, 4 x 4: 15 points.
ATTENTION: player should make their move within 15 secs. Otherwise, opponents could “help” them do this step if it takes more than 25 secs. Winner would win a red stamp, loser would win a blue stamp, and if you reach the maximum of two within these two lattices and will be not allowed to participate again. The one who wins the 4 x 4 lattice would only have one chance to take the 6 x 4 lattice, and if he loses in the 6 x 4 lattice, he will bear the risk of losing the second game and obtaining nothing. The one who loses the 6 x 4 lattice could change to the 4 x 4 lattice to have a try. |
| Table 4 | Mancala | One-on-one PK.
Two volunteers needed. Two props available. |
30 points (If there is a tie, then both two would receive 15 points, and mark “15” with pens).
ATTENTION: player should make their move within 30 secs. Otherwise, opponents could “help” them do this step if it takes more than 45 secs. Winner would win a red stamp, and not allowed to participate, loser would win a blue stamp, and if you reach the maximum of two, and will be not allowed to participate again. |
| Table 5 | Rubik’s Cube | Solo.
One volunteer needed. Two cubes available. |
25 points (40 s), 20 points (1 min), 15 points (3 mins), 10 points (5 mins).
Winner would win a red stamp, and not allowed to participate, loser would win a blue stamp, and if you reach the maximum of three, and will be not allowed to participate again. |
| Table 6 | Number Bomb | One-on-one PK.
One volunteer needed to determine the random number. The one who guesses the number between 1 and 100 correctly will lose. |
10 points.
Winner would win a red stamp, and not allowed to participate, loser would win a blue stamp, and if you reach the maximum of three, and will be not allowed to participate again. |
| Table 7 | Ticket Office | With limited math lantern riddles, to get bonus points.
Lay the Lottery Box. Two volunteers needed. |
5 points for each, and each participant could win 10 points at most. Those who have been guessed correctly will be recycled. |
Detailed rules for redeeming prizes:
- General rule:
The allocation of prizes follows the rule of first-come-first-serve, and those who have exchanged the gifts would consume the points they have obtained, and not allowed to change the gift with their points originally owned. Candidates for the Surprise Awards List follow the rule of points-time priority principle, that is, sorted by points, with those who share the same point, sorted by the time when they confirmed their points in the ticket office. By the way, those who have confirmed their points are not allowed to win more points from the game.
| Prizes | Quantity | Points | Estimated Price |
| Nintendo Switch | 1 | 130 | 2000 |
| Surprise Awards (Computer Monitor, BEATS Bluetooth Speaker, Kindle, LEGO, Polaroid, JD Gift Card) | 9 in total | 100 and above | 500 and above
Can choose one from the Wish List. |
| BEATS Neck-mounted Earphone | 3 in total, with one in lottery | 85 | 400 |

Pi day talk

TOPIC: On the origin and history of pi

TOPIC: Making taffy with the Golden mean
SPEAKER: Jean-Luc Thiffeault, University of Wisconsin — Madison
Abstract：Taffy pullers are devices used to make candy or bread. They work by
repeated pulling and folding of the dough, and lead to exponential
stretching. They are mathematically fascinating: we can relate the
number of folds of dough to famous mathematical sequences, for example
the Fibonacci sequence. Some surprising numbers pop up, such as the
Golden mean, but also its lesser-known cousin the Silver mean. We can
use this knowledge to improve existing devices, and we propose a novel
design that is based on solid mathematical foundations.
