When I was younger I learned in Chemistry class that Anions were negatively charged and Cations were positively charged (Fun fact: I memorized this because anion sounds like onion which makes you cry and is therefore negative; while cation has cat in it and cats are cute, so it's positive :P).
Now that I've started getting into electronics, I've learned that the Anode is the positive lead while the Cathode is the negative one. It seems odd to me that they're reversed; can someone explain why this is?
