like yes he’ll snap at you if you break his concentration or you’re doing an important job badly; but one thing I think both Rathbone and Cumberbatch leaned on a little too heavily for my liking in different ways is that he was also sometimes a jerk TO THE CLIENT, and that I think I object to

Article. I can read faster than any YouTuber can speak, even with the playback speed cranked up to comical levels.
THAT SAID, article writers these days need fucking EDITORS they spend whole paragraphs FAFFING ABOUT before they get to the point IT'S CALLED THE INVERTED FUCKING PYRAMID MY DUDES

The real generational divide is people who refuse to watch a video if it could be an article versus people who refuse to read an article if it could be a video

Science friends! If you could go back in time and tell your first year self one piece of advice about doing STEM at the graduate level, what would it be?

Glad to hear that Sanctuary Moon is called a planet in its theme song!
That alternate future? universe? has the same problems we do with calling everything roughly spherical a planet!

The niche problem of the podcast you’re listening to saying the composter Haydn’s name like the planetarium in NYC, I don’t know podcasts can jump scare you

The argument here is hilarious, which was when book rate/media mail was invented it was so people could access the dictionary as easily as dirty photos.
I’d like to think we’ve moved a little beyond that reasoning, as regardless making education easily accessible is critical to democracy.

Save a little rage for the elimination of the USPS Bound Printed Matter rate.
It hasn't happened yet - the PRC (Postal Rate Commission - denied the recent USPS request to do so.
But with rates going up *again* on July 13, this special rate for book shipping will be de facto eliminated soon.

And most spacecraft science and ops team members were trained on other projects from the ones they’re currently working on—it’s like a community and ecosystem is supported by what is not a huge fraction of the overall federal budget!
Hal Levison at #SBAG makes the excellent point that because of the way the field works - everyone shares resources, and most people work on more than one program - even though Lucy is funded in the PBR, the effect of the proposed cuts would be 3-4x Lucy's reserves. Tell your reps to save US science!

Once again begging media reports to get the math right. For example, cutting a $5M five-year grant in year 4 isn't saving $1M, but it is wasting the $4M already spent. Stop letting this administration get away with so many lies.

And! Never went to the Vancouver Aquarium on a school field trip again, even though we were so very close to the border, because ~40 people’s passports were far too many even without most of those people being 12 or under
Don’t fly May 7th. I was a congressional intern the summer that the U.S. began requiring passports to travel on land between the U.S. and Mexico/Canada. It was a complete shitshow. Passport delays reached months. People were calling up constantly for help to avoid having to cancel their vacation.
hint: I am absolutely talking about blaming Real ID deadline chaos 100% on Donald Trump

Figuring out how to do something in space the first time is a heroic undertaking from so many team members. Figuring how to do it again after a generational gap in knowledge?
There are reports The White House is considering a 50% cut to NASA’s science programs, and 25% of its overall budget, which would be catastrophic for both current and planned missions. But, there is still time for the administration to reconsider. Read our full statement ⬇️
