Oof. I get that. I just got a new record player from my employer as a work anniversary gift, and a lot of the vinyls on my wishlist are no longer pressed.
I first listened to Magic Sword when the Thor Ragnorak trailer used "In the Face of Evil" Definitely one of my top artists!

Good choice! I love the Escape Velocity album.
I've also been listening to some Waveshaper recently, but sometimes it's too exciting.

#WritingCommunity Iโm looking for some good ambient music to write Sci-Fi to. Usually I put on some Vangelis or Phillip Glass (Koyaanisqatsi is a favorite) for most of my writing.
What go to songs or albums do you have?

I just realized the novel Iโm working on, a hard SF adventure to save people from a plague, is well on its way to being over 100,000 words long, with my target of 160,000 being just right.
Word count isnโt everything, but Iโm a sucker for a thick book.

Something I forget about is microfluidics, and they have great potential to be useful.
In addition to computation and miniaturized diagnostics, it could be possible to make channels small enough peel off the carbon atoms off of CO2 molecules.
Imagine the possibilities for carbon capture.

With 1 person per square mile, the population density of Alaska, it would fit 65 trillion people.
It is insane to think about, but structures like this could exist in our universe, or we could build it ourselves one day.
Science fiction often misses how big spacefaring civilizations can be.

If we built a shell around our sun so the gravity from the sun is equal to Earth's on the surface of that shell, this shell world would have a surface area of 1.7*10^20 m^2, or 333,000 Earths.
Each square meter would receive 2.2 MW of power, or enough to run 4,000 refrigerators.

Happy Moon Landing Day everyone!
It's been 56 years since Neil Armstrong and Buzz Aldrin landed on the Moon.
I hope to live to see a Moon/Mars landing myself. My father was a wide-eyed 13 year old kid when he saw history being made.
That said, I hope the Senate budget for FY26 allows us to do so.

I have not been able to write for a week because my keyboard died and the new one hasn't shipped from Amazon. Instead, I've read a lot.
So, I finished the Voyagers by Ben Bova, The Shadow Rising by Robert Jordan, reread The Hunt for Red October, and now I'm reading John Glenn's memoir.

120 years later, a thermodynamics puzzle is cracked, Professor Josรฉ Marรญa Martรญn-Olalla showed that the Nernst theorem about how entropy (disorder) behaves near absolute zero is actually part of the second law of thermodynamics. Even Einstein thought it was a separate rule.

Finally finished "Wernher Von Braun" by Erik Bergaust.
It was a great, long read. It's also interesting because the publisher, the NSI is now the NSS.
If you're interested in a biographical profile from a close friend of von Braun, it's a great source.

Well, rejected by Analog again. My fortune cookie said "You'll find new purpose in July." I guess that wasn't what it meant.
But, I haven't given up yet! Let's see if anyone else likes it!
