> 1. No result is 100% reproducible because you can never completely reproduce the conditions of any experiment. It's worth noting that this is part of the goal of reproducing results. If two identical experiments produce the same result, you're only providing proof for the very narrow theory the experiment tests. Slightly different experiments allow you to demonstrate that the theory is applicable. Imagine if evolution only occurred in the Galapagos, or if gravity only worked in an apple orchard in Cambridge. The only reason we know that evolution and gravity aren't local oddities is that they have both been tested in a wide variety of locations, with a wide variety of experiments.
