In the mid 1960s American mathematician Stephen Schanuel devised a complex mathematical conjecture regarding the 'transcendence degree' of certain 'field extensions' of the rational numbers.

Formally stated :

Given any n complex numbers z₁, …, z_n that are linearly independent over the rational numbers Q, the field extension Q (z₁, …, z_n, e^z₁ , …, e^z_n) has transcendence degree at least n over Q

At present, the conjecture has neither been proved or disproved.

An irrational number is a real number that can't be expressed as a ratio of integers, i.e. as a fraction.

Put another way, it can never be specified with absolute accuracy.

Well known examples are π and √2

For many irrational numbers, relatively simple mathematical proofs exist which show that it's impossible to ever arrive at a finite solution. For example, such as π and the natural logarithm e.
