I have a different answer from Jon's which is my understanding and which I
hope is helpful. Every rational number (the ones physicists use, like 2.0)
is also a real number. They also use truncated irrational numbers like pi
and sqrt(2) in their calculations--that is, 3.14159265 (a rational number)
instead of pi. They use pi in theoretical derivations. As Jon says, there
are uncountably many non-rational numbers.
As for sensitivity to initial conditions, physicists or engineers calculate
the trajectory of a probe to Pluto and they launch with an initial impulses
or set of impulses which won't result in an exact arrival at Pluto. The
saving grace is that they can apply small impulses (f*deltat) later in the
trip to make corrections.
