MTorrice writes "When energy companies extract natural gas trapped deep underground using hydraulic fracturing, they're left with water containing high levels of pollutants, including benzene and barium. Sometimes the gas producers dispose of this fracking wastewater by sending it to treatment plants that deal with sewage and water from other industrial sources. But a new study (abstract) suggests that the plants can't handle this water's high levels of contaminants: Water flowing out of the plants into the environment still has elevated levels of the chemicals from natural gas production."
Thus mathematics may be defined as the subject in which we never know
what we are talking about, nor whether what we are saying is true.
