His interest in chaos came about accidentally through his work on weather prediction in 1961.[12] Lorenz was using a simple digital computer, a Royal McBee LGP-30, to run his weather simulation. He wanted to see a sequence of data again, and to save time he started the simulation in the middle of its course. He did this by entering a printout of the data that corresponded to conditions in the middle of the original simulation. To his surprise, the weather the machine began to predict was completely different from the previous calculation. "

So, either he mis-entered something, or possibly the result of a
different state of a random number generator somewhere?
