Simuler grâce aux ordinateurs

Computer simulation renders us immense services every day. With the substantial help of supercomputers, the resistance of a bridge, meteorological phenomena, etc., can be predicted in advance, considerably limiting costs and risks

But how are these simulations carried out, and what limits do they run up against? Answers will be provided through playful examples that will also help understand why certain predictions are more about clairvoyance than science!
