Math Behind chatGPT
Click 3 emojis to build an equation (A - B + C). AI converts concepts into numbers (vectors), does math with them, and finds the closest match - like how Netflix knows similar movies or Spotify finds songs you'll like
Shortcuts in Google Maps
Click any box to start a nearest-neighbor heuristic that finds the highest number without checking every cell - like how Google Maps finds a good route fast without exploring every possible path.
Quick Search in Amazon
Watch sorting algorithms race to organize the same numbers. Quick Sort’s divide-and-conquer strategy—much faster than Bubble’s compare-everything—powers the fast data sorting behind Google and Amazon.
