As a boy I loved by the story of the king, the sage and the chess game. It made me grasp the power of exponential growth. Today it is important that everyone understands this! Depending on country, Corona cases are doubling every 3-6 days. #covid19
Remember story of Indian king betting on chess game with 1 grain of rice, doubling on subsequent square.. Led to 210 billion tonnes on 64th square.. That's why Coronavirus exposure projections can be `wild' but yet possible
Exponential growth: Rice & the chessboard story Grain of rice for the first square on the chess board, 2 grains the next square, 4 grains for next square & so on. 64th square=~534,955,578,138 *TONNES* of rice 2019 Global rice production= 499,310,000 tonnes
