OK Twitter, I'm going to say a bunch of things...

You don't need to read it, but I need to write it. 1) we need clear & enforced codes of professional conduct. If you harass a student, you should lose your job. I have friends who have been harassed AND friends who have lost their jobs for harassing. I have no stomach for people (esp. men) who treat people so poorly.

It’s Friday movie night, kids get to choose… so we’re on probably the 20th viewing of *shudder* the Paw Patrol Movie. AND I HAVE SOME THOUGHTS
1/ There’s so much to ponder about the Adventure Bay Universe… the perineal favorite Q is “Where the hell are Ryder’s parents?!”
But with today’s viewing we’re considering the logistics (and timing) of the Paw Patrol’s arrival in Adventure City

Hot dog! Astro Twitter is fired up today about a paper on metrics & research/career "impact"! I don't approve of the premise, method, or conclusions of this paper (also, these metrics as a "predictor"?! lol), but here's my 2 thoughts... 1) I've never seen any evidence that astronomers have skill at picking the "best" people for anything (jobs, grants, etc). I've 🧵'd about this, @astrogrant has write ups. *maybe* we can sort applications into a few meaningful piles

Funny fact: when you're trying for that output PR on @onepeloton, you're *NOT* chasing your previous best ride. Peloton takes your best total output (in kJ) & updates it evenly spaced throughout. Here I jotted down my PR output every 10sec over a 5min ride (pink line) Image The blue line is a fake representation of what the output might have actually been for that PR (Personal Record, aka Personal Best/PB) ride, slowly warming up, & then taking a break at the end (many rides have a warmup/cooldown built in)

It's perhaps a small thing, but @JoeBiden doesn't use a Sharpie to write. I find that comforting. Nobody serious about communicating or ideas uses a sharpie to take notes in a meeting

This looks like a @officialuniball pen, maybe from the Vision line? Image No @Sharpie hate here - they're my go-to for lots of jobs in the shop or around the house! @hankgreen, certainly someone who cares about ideas and communication, recently said they're the best for signing books.

But you're not taking notes on complex global issues w/ a Sharpie

Free sitcom idea: it’s like Parks and Rec, but it’s the company who “lost” the bidding war and now has to build the Trump Presidential Library “Lost” b/c Trump is a real estate developer, so of course he’ll put a bid in to build his own library to try and enrich himself further. But he’s really a pretend developer, and so hires the company that lost the bid to secretly do it anyway but for less $

I've seen a lot of chatter about collectively using box fans to - for example - clear smoke from the #wildfires... heck I've even had that thought! So last night I did some fast math:

a 🧵 I live in Seattle suburbs, so we're just going to focus on WA (sorry OR & CA, you're on your own). WA has an area of 71,362 sq miles. Smoke can rise HIGH, but 2km of air should be plenty to breathe, e.g. earthobservatory.nasa.gov/images/144658/…
So we need to move... ~1.3e16 cubic feet of air(!)

Today a student asked me: How did you get over the worry of asking a "bad" question?
My short answer: By asking a lot of bad Q's...

My long answer: {Mind you, all this is from my extremely privileged life and esp. current position}
I finished college w/ a C average (which I maintain is A OK!), didn't get into any PhD programs, and felt like I never really "got it" in most courses (astro being almost the only exception).

Look at this desk
Isn't it neat?
Wouldn't you think my home office’s
complete?
Wouldn't you think I'm a girl
Who doesn’t have COVID19? Look at this pantry
Treasures untold
Just how much TP can one cabinet hold?
Look at my stockpile you'd think
(Sure) she's got everything
