I really like @FiveGuys, but they always make this fucking mess of your takeout bag where the fries are dumped everywhere and making the bag fall apart from grease. Every time I go, it pisses me off enough to keep me away for months.

Hey @peacock how do I cancel my plan while out of the country? The website simply refuses to do anything, even give me contact info so I could call/email someone!

We shall measure stellar brightness logarithmically, and it will be called the "magnitude." - Sir, will that logarithm be base 10, or based on Napier's constant? Neither. It shall be of the base of the fifth root of one hundred.

Hello new followers! I'm mainly on Bluesky these days (@astrobailin.bsky.social), but when I'm here I mainly post about astronomy, and sometimes US politics, coffee, Canada, Alabama football, and cats.

Has anyone used Sirola's "Conceptual Astrophysics" to teach an upper-level course (lots of math but no calculus)? Would love to hear thoughts, both good and bad.

People keep saying "unprecedented" like there's never been an election when a Dem incumbent drops out, RFK is running, the Dem convention is in Chicago, there's an unpopular foreign war, the Rep nominee is a crook who thinks he's above the law, and a leading candidate gets shot

I’ve known Vice President Kamala Harris for a long time. She’s a tenacious fighter, a champion for our rights & defender of our democracy. United, she will lead us as we defeat Donald Trump this November. I am proud to endorse Vice President Kamala Harris as our Democratic nominee. Let’s go!

Harris was my top choice last time, and I’m ecstatic to be able to vote for her this year!!

My fellow Democrats, I have decided not to accept the nomination and to focus all my energies on my duties as President for the remainder of my term. My very first decision as the party nominee in 2020 was to pick Kamala Harris as my Vice President. And it’s been the best decision I’ve made. Today I want to offer my full support and endorsement for Kamala to be the nominee of our party this year. Democrats — it’s time to come together and beat Trump. Let’s do this.
