Lily Serna uses math to find the best of 17 surfing beaches. She illustrates the equation supporting Optimal Stopping. Serna finds ideal conditions at the thirteenth location.
Math Magic (04:20)
Serna asks fair-goers to choose a number between one and ten, apply a series of operations, and imagine an animal alphabetically corresponding to the result. She accurately predicts choices, explaining that any digit multiplied by nine results in a number whose digits add up to nine.
Winning Zero Sum Competitions (03:45)
Serna teaches friends how to apply John Nash’s Game Theory to win at Rock, Paper, Scissors. Winners repeat their plays, while losers change their choices; she consistently predicts opponent’s moves.
Algorithms: Directional Challenge (06:38)
Serna creates an orienteering course, giving three teams navigational maps based on formulas or human intuition. The Optimal Algorithm group should finish first; their map mathematically plots fastest routes, but does not include terrain or obstacles.
Algorithms: Employee Optimization (04:13)
Serna tours the E-Store Logistics distribution center; warehouse workers receive automated instructions formulated for efficiency. All workers’ movements and decisions are made by computer.
Algorithms: Cognitive Collection (04:44)
Couture designer Jason Grech predicts fashion trends with a formula created by IBM. The Watson computer converts photos of inspirational subjects into dress patterns.
Algorithms: Directional Challenge Results (04:13)
The orienteering course represents the Traveling Salesman Problem. The team using the Nearest Neighbor formula wins the challenge; the Human Intuition players reach the fewest checkpoints.
Queuing Theory (04:20)
Serna goes grocery shopping, illustrating how to pick the fastest moving line; each customer spends 40 seconds interacting with clerks. Serna explains right side bias commonality and demonstrates the most efficient check-out system.
Monty Hall Dilemma (09:20)
Serna stages a game with a prize in one of three boxes. Participants guess which box has the prize, view a dud, and receive the option of changing their choice. Conditional Probability states chances of winning will double if they change.
Predicting Weather (06:13)
Serna enlists a pool champion to illustrate chaos theory. Sydney’s Bureau of Meteorology uses the chaos theory, human experience, and algorithms formulated from global data to anticipate weather systems.
Applying Logic (02:22)
Serna defines intelligence as the ability to adapt to change. She asserts that pattern recognition is hardwired in humans, allowing us to make predictions and informed decisions. See a trailer for the next episode.
