All the years I taught multi I would have liked to have had this for just that intuition about divergence and curl!
Brilliant exercises for developing intuition about divergence and curl, from Purcell’s book on electricity and magnetism. “Four of these vector fields have zero divergence in the region shown. Three have zero curl. Can you spot them?” (I’ll show solutions lower in the thread.)

Trump shouldn’t make fun of @JoeBiden and his drive-in rallies. At least his supporters have a way to get home afterward and don’t have to wait in the freezing weather for buses that don’t show up

Now that charges have been filed against all of the killer cops for George's death. @MayorFrey, you must hold the entire MPD accountable and defund them. Invest in thriving communities, not killer cops! #DefundtheMPD

Dr. Birx is going to leave a horrible legacy. It's one thing to be a cynical paid fixer. It's worse, in my eyes, to be the expert who props up the mad king. I get that it's an emergency & I understand the theoretical strategy she may think she's pursuing, but it's a moral horror.

Steve (the plant Stephen nurtured for 40+ years) has never looked this good at the end of winter before! I wonder whether Victor has been serenading him when I’m not looking.

What I would like to know is just what Mr. Trump is (or thinks he is) president of, since he is clearly NOT the president of the UNITED states of America as evidenced by his unwillingness to LEAD the United States of America.
