Good morning. The day I feared has come to pass: Heavyweight is now a Spotify exclusive. I’m very concerned about this and also about the future of our country, but I’m trying not to let it ruin my weekend.
Here's some fun stuff for you to look at:
Item 1: a link
I'm not particularly proud of linking to some shameless promotional material but I did enjoy this set of silly old school Microsoft-themed images. And it's nice to see them leaning into how stupid Clippy was.
Item 2: a list
Main Sequence Stars, Ranked:
- Blue stars (“Because blue stars are so hot and massive, they have relatively short lives that end in violent supernova events, ultimately resulting in the creation of either black holes or neutron stars”)
- K-type stars / Orange Dwarfs (“K-type stars are of particular interest in the search for extraterrestrial life, since they emit markedly less UV radiation (that damages or destroys DNA) than G-type stars on the one hand, and they remain stable on the main sequence for up to about 30 billion years, as compared to about 10 billion years for the Sun”)
- G-type stars / Yellow Dwarfs (“Like the Sun, all G-type stars convert hydrogen into helium in their cores, and will evolve into red giants as their supply of hydrogen fuel is depleted”)
- Red Dwarfs ("The process of nuclear synthesis happens so slowly in these that the Universe is not old enough for any known red dwarf star to have aged into an advanced state of evolution”)
- O-type stars that are not Blur stars (not described on the only website I looked at, but they seem to be very hot)
- M-type stars (not described on the only website I looked at, but they seem to be very cold)
- A- and F-type stars (not described on the only website I looked at, but they seem to be very medium temperature)

Item 3: a media recommendation
Item 4: a photograph
Thanks as always for reading. You're a very smart person with excellent taste. Have a wonderful weekend - see you next week!
And get your flu shot.
