  Most physics theories are deterministic, with the notable exception of
quantum mechanics which, however, comes plagued by the so-called measurement
problem. This state of affairs might well be due to the inability of standard
mathematics to "speak" of indeterminism, its inability to present us a
worldview in which new information is created as time passes. In such a case,
scientific determinism would only be an illusion due to the timeless
mathematical language scientists use. To investigate this possibility it is
necessary to develop an alternative mathematical language that is both powerful
enough to allow scientists to compute predictions and compatible with
indeterminism and the passage of time. We argue that intuitionistic mathematics
provides such a language and we illustrate it in simple terms.
