The Omicron variant is spreading rapidly: doubling in size every two days. Even someone as innumerate as me (I failed Elementary Maths O-level four times, or maybe five) can grasp the exponential implications. According to a famous mathematical puzzle, if a chess-board were to have grains of wheat placed upon each square - with one grain on the first square, two on the second, four on the third, and so on, doubling the number of grains on each subsequent square - how many grains of wheat would be on the chessboard at the finish? The total number of grains is huge, representing the annual world production of wheat multiplied by 2,000.
