No, we can’t predict the weather   To summarize the problem,
(though you should really read James Gleick’s 1988 masterpiece
Chaos: Making a New Science) in the 1950’s, a former Army
forecaster turned his attention away from near-term meteorology
and toward long-term predictions using the new-fangled
technology of computers. He figured you plug in the known
equations, let it run for a while, and the model spits out an
easily repeatable, verifiable result.  What he discovered
instead is that, even when he used the simplest set of equations
and initial assumptions representing the earth’s atmosphere, he
couldn’t predict the results. That is, even though he fed
relatively simple information into his computer – this was a
time when computers were room-sized and had fewer capabilities
than your coffee machine – there was no way to predict the
outcome because tiny differences (on the order of a thousandth
decimal place) in the initial parameters had a drastic impact on
the final result.  And so we can’t tell for sur
