The truth is not the average of a fact and a lie.

One of the big issues I have with this rocket - and there are many - is that it's finicky and it costs a fortune every time they have to haul it back. Plus it can only launch once every two years. Plus it's like $4B per launch for Artemis.

One cool thing we've noticed here in Texas is how many Kestrels there are--they seem to be on every stretch of electric power lines. I captured this one as it took off in pursuit of dinner. 😎😎😎 #Kestrel #Texas #birding

Tomorrow morning the Waning Crescent Moon will occult (eclipse) the star Tau Scorpii, with Antares nearby. Look south from 5.45am. πŸ”­ πŸ§ͺ

Black and white photograph of Emmy Noether. She is standing just behind an ornate chair, wearing a white striped blouse with puffy shoulders, a fluffy bow at her neck, and a heavy long skirt cinched with a belt. Her dark hair is pulled back and she is looking a bit to the photographer's right.

Felix Klein lectured β€œOn Hilbert’s first note on the foundations of physics" at the Mathematical Society of GΓΆttingen #OTD in 1918. He included excerpts from letters in which he and Hilbert give priority to Emmy Noether’s results on conservation of energy in general relativity. (1/n) πŸ§ͺ βš›οΈ πŸ‘©β€πŸ”¬

Our government is out of control. This is CLEARLY a violation of the 4th amendment.

I think someone should add my Olive Oil waveguide antenna, nay "Cantenna", for my backyard horn radio telescope to this wiki page!

The dimensions of the olive oil can are awesomely perfect for the 21cm neutral hydrogen signal!

The Phlogiston Theory – Wonderfully wrong but fantastically fruitful There is a type of supporter of gnu atheism and/or scientism who takes a very black and white attitude to the definition of science and also to the history of science. For these people, and there a…

So great achievement!

A research team has recently proposed a new way to detect gravitational waves (GWs) in the elusive milli-Hertz frequency range (mid-band).

If you have a college freshman who is not yet 18, please make sure they have a signed "permission to treat" form with them on campus until they are 18.
(This may apply to the United States only. I don't know about other places.)

A damp and somewhat dreary morning in Central Park, but I was happy I brought my camera when I happened upon this cute little Ovenbird hopping along the path. Do you know why they're called Oven Birds? Answer below! πŸ₯°πŸ₯°πŸ₯° #fallmigration #CentralPark #birding

My daughter's friend had an accident today that resulted in an injury that required stitches, and they had to go to FOUR places before finding one that would treat her because she was under 18 and didn't have either a parent or a signed "permission for treatment" form with her.

An amazing number of people didn’t bother to read this story and thus don’t realize the 37 year old man mentioned here was *horrified and reported it* - he is not the problem here! Mark Zuckerberg’s historically evil company is!

Nations ratify the world's first treaty to protect international waters The first treaty to protect marine diversity in international waters will come into force early next year after being ratified by the 60th nation, Morocco.

The High Seas Treaty has been ratified! While there seems to have been a lot left out, it's a good step to protecting the ocean worldwide apnews.com/article/high...
