Still not as fun as spin up/spin down quarks. Are they spinning? Not at all. And Charm quarks. What the hell does that even mean, science nerds? We also have the strange quark… aren’t they all really strange or have you just completely given up?

The hypothetical particle names get messy, lol.
explain this one to me?
adding to abnorc’s excellent answer - circuit diagrams are all drawn as if charge carriers are positive (this is called “conventional current”), but because electrons are negative, this can get very confusing when you’re dealing with components where the flow of charge is one-way only (diodes, transistors, batteries, photometers…)
In Benjamin Franklin’s experiments, he came up with the convention that we use today to define a “positive” charge. As it turns out, electrons, discovered much later, are negatively charged according to the convention. Lots of chemical and physical reactions involve electrons as charge carriers, so lots of physical phenomena have this weird opposite thing going on. E.g. electric current or “conventional current” flows in the opposite direction of electron current. Chemical reactions are also weird. Reduction reactions involve a reduction in electric charge, but gaining an electron. The model works just fine, but it can be tricky and/or annoying at times.
What if I told you the original selection of terms “positive” and “negative” was arbitrary?
Anyway a positively charged electron exists. It’s called a positron.
No, I think it makes sense.
Living organisms use ions internally (positive charges) because they produce something (like fruits).
Technology uses negative charges because it harvests those fruits, and takes them away (negative).
What if we just assume current flows from negative to positive?
