  • My brother is an audiologist and hates doing a certain hearing test, because it’s boring. The way he describes it, he hands the patient a button and a pair of headphones, then goes into the next room.

    He has a row of dials. He turns the first one until the patient pushes the button. He writes down how high the dial got, then turns it off and moves on to the next dial. Repeat for like 20 dials.

    Then at the end, he has to draw a graph BY HAND, highlighting certain features.

    There is precisely 0% chance that this requires a trained audiologist to do. Maybe to interpret, but not to collect data.














  • The oxygen atom in a water molecule has an oxidation number of -2 (which is as reduced as it can get in common compounds you’re likely to find, and it has no reason to react further). In hydrogen peroxide, the oxygen atoms have an oxidation number of -1, so not quite as reduced as oxygen would rather be (which is why H2O2 is gonna oxidize whatever is around it. Those oxygen atoms are gonna get those sweet, sweet electrons one way or the other by god!)

    The hydrogen atoms are identical between H2O and H2O2; that’s not where the magic happens, so to speak.
