Wow! Well how about that….

Ha!!

Doctor measuring my pulse: "Whoa -- have you been eating sugar cubes out of the box again? Oh wait -- never mind -- I've been measuring in summer seconds, not winter seconds." (Also, Olympic events would be soooo messed up -- I like it!)

I feel like keeping the jump at a constant 2 seconds makes it too easy for folks. May I suggest that the interval change gradually over the course of the year (i.e. fractions of seconds)? 🙃

Challenge! Daylight Time "solutions," but each one has to be worse than the one before. I'll start: Instead of a one-hour switch twice a year, how about 4 forward jumps of 15 min each, at one-week intervals, in the spring, and 4 backward jumps of 15 min each, at one-week intervals, in the fall. 🙃

And the prize for fakest of all fake astronomy pictures (of which there are a zillion) goes to the pic of Jupiter *inside* the crescent moon. 🤔🧐🙄

Paul McCartney's decade of transformation: From Beatles breakup to John Lennon's murder Man on the Run shows McCartney's effort to define himself outside The Beatles' shadow: "Paul making this documentary was a way of coming to terms with that whole period," says director Morgan Neville.

The “every field” thing is so out there.

Fireball and sonic boom over Vancouver was likely meteor British Columbians took to social media Tuesday evening to share reports of a bright fireball in the night sky over Vancouver, and a house-rattling sonic boom.

Tuesday night brought a bright meteor / fireball to the Vancouver area, plus a loud sonic boom:

Happy Proceed Forward Day! :)

Meet three scientists who said no to Epstein The warning signs included a web search, a mother’s doubts, and inklings of a “sexist attitude”

Many of the scientists Jeffrey Epstein courted were already well-established and well-funded. So why didn’t they all just say no? Science talked with three who did just that.

Here’s how Epstein approached them, and why they refused to have anything to do with him. ⬇️ https://scim.ag/40qbXnv

Oh, I'm sure you're not alone. (When I did a very informal survey on the old site some years back, it seemed there was roughly an even 3-way split between year-long ST, year-long DT, and the status quo.)

Dawn Delight: Total Lunar Eclipse on March 3rd March opens with a spectacular total lunar eclipse. Our guide will help you make the most of it.

Lunar eclipse coming up! West coast folks will need to stay up late (totality begins 3:04 am PST); east coast peeps will have to get up before dawn, and the moon will set with the eclipse still underway (totality begins 6:04 am EST). @skyandtelescope.bsky.social

Wow. (F-15’s don’t even look like that.)

It’s so good!

To maintain the cosmic balance, an astronomer on Ellesmere Island needs to be interviewed about whatever southern-sky events are happening this week. :)

Cool!! Will read with interest!

NASA announces sweeping changes to its Artemis lunar program | CBC News NASA Administrator Jared Isaacman has announced that the Artemis III mission, which aimed to put humans back on the moon, would no longer head to the lunar surface, but instead focus on testing spacec...

NASA alters #Artemis plan: Artemis III no longer a moon landing; instead they'll test docking equipment in low-Earth orbit. (Artemis II still scheduled to loop around the moon.) via @nebulousnikki.bsky.social www.cbc.ca/news/science... #NASA

Half the job ads on LinkedIn are basically "Help train the AIs that are going to replace you in a couple of weeks, and with luck the whole department also."

Many congrats!! (And welcome to the club! :) )

Oh no! Well, any chance you can catch an Artemis launch…?

How Darwin's 'Descent of Man' Holds Up 150 Years After Publication Questions still swirl around the author’s theories about sexual selection and the evolution of minds and morals

On the Origin of Species was just the beginning: Darwin was still developing his ideas on sexual selection & the evolution of minds & morals. These surfaced in his 2nd major work, The Descent of Man, pub #OTD in 1871, as I wrote for @smithsonianmag.bsky.social: www.smithsonianmag.com/science-natu...

I still can’t fathom that the solar eclipses of 2017 and 2024 lay in the past 🫥

Nobody ever talks about the crappy Gabor paper any more. I kinda miss those days.

In the Footsteps of Copernicus YouTube video by danfalkscience

2/2 I also made a video exploring Copernicus's life and science in which we walk in his footsteps, in #Poland (Warsaw, Frombork, Torun, and Krakow). #Travel meets #science! Enjoy! youtu.be/wqRj0HgIaiE?...

1/2 Happy 553rd Birthday to Nicolaus Copernicus, born #OTD in 1473. A while back I wrote a fun article for @astronomymag.bsky.social about how Copernicus re-shaped our understanding of the cosmos: www.astronomy.com/science/how-... #science #history #histsci
