  • Magnets.

    If there’s no field there’s 0, if there’s a magnetic field clockwise it makes a positive charge, if there’s a magnetic field rotating counterclockwise it makes a negative charge,

    Likewise if there’s a positive charge it makes a clockwise magnetic field and if there’s a negative charge it makes a counter clockwise field. (I may be backwards +/- clockwise/counter clockwise, something about the thumb on my left hand…, but really it’s all arbitrarily named, but the reason you just say negative or positive is that those are scalable measures, you can’t have half a Bob or 2 Alice. )

    Huh??

    There are more identified species of cichlids in lake Victoria than there are of all terrestrial vertebrates.

    There are different species of trout and Salmon that are outwardly identical (need to look for throat teeth).

    An icthyologist did not have say in writing this meme.
