What Work Is with the working class or work in general. This helps place this collection within the tradition of working class poetry. For instance, besides work, love also is a major theme for Levine in this collection. "What Work Is" is a poem primarily written for his brother, and the difficulty of expressing that love. Often enough the theme of love is expressed in a subdued way and is shadowing the bolder themes most largely associated with work. The poems feature different types of work, some of which reflect the actual work experience of the author. For instance, the poems "Fear and
Proof that e is irrational numbers. Still another proof can be obtained from the fact that Define formula_11 as follows: Then: which implies: for any integer formula_15 Note that formula_16 is always an integer. Assume formula_17 is rational, so, formula_18 where formula_19 are co-prime and formula_20 It's possible to appropriately choose formula_21 so that formula_22 is an integer i.e. formula_23 Hence, for this choice, the difference between formula_22 and formula_16 would be an integer. But from the above inequality, that's impossible.So, formula_17 is irrational. This means that formula_27 is irrational. In 1840, Liouville published a proof of the fact that "e" is irrational followed by
