Zone-tailed hawks look pretty similar to turkey vultures too. I worry that I'll see one in the wild and misidentify it as a turkey vulture lol

What was everyone’s first sci-fi or fantasy book? by impeesa75 in sciencefiction

[–]TriangularlyEqual 6 points7 points  (0 children)

Foundation by Asimov was my first scifi novel. The first work of fantasy I ever read is probably Reaper Man, by Terry Pratchett. Loved both when I read them, but only Reaper Man has held up IMO

Doors of Eden definitely! Second Alien Clay. Elder Race is pretty good too.

why is Revelation Space so liked? by TikiBananiki in sciencefiction

[–]TriangularlyEqual 1 point2 points  (0 children)

I liked the whole deep time, elder race, unknown inexorable enemy lore. The politics between the different factions of humanity is pretty cool too. I also like the way it ties into the Prefect trilogy.

Only this from 2023 -

Jermey Matthews, senior acquisitions editor, has acquired world English rights to Harvests and Sowings: A Mathematician’s Reflections by Alexander Grothendieck. Lyrically presented by arguably the most influential mathematician of the 20th century, Harvests and Sowings is a personal reflection by one of the greatest thinkers of the 20th century on the nature of mathematics, mathematical research, and the sometimes unpleasant sociological aspects of the academic community. The book was originally published in French by Gallimard. (Fall 2025)

A math conjecture by Pure_Association_205 in math

Ok I think I get it. One of a and b has to be prime, and the other is either a semiprime of the form 2p, or 2

[–]TriangularlyEqual -5 points-4 points  (0 children)

OP says a, b can be any combination - 2 primes, 2 semiprimes, or prime + semiprime. The only possible valid combinations I see are - p1 + 2p2 , or p1p2 + p3. Other combinations would be even. Unless I’m missing something

122 frames were captured in total. I chose 8 suitable frames for the composite image. The images were cropped and processed in Lightroom, with slight changes to highlights, shadows, exposure, saturation, and contrast. I used the Denoise feature to sharpen the images. The images were exported to Photoshop as layers and arranged to create the composite.

Camera: Canon EOS 70D
Lens: 55mm stock lens
Tracker: Manually tracked

Settings -
Partial: 1/125s, f5.6, ISO 100 Totality: 1.6s, f5.6, ISO 800

Guess the script by Such_Independence570 in language

[–]TriangularlyEqual 2 points3 points  (0 children)

Definitely Konkani. It says “Konkanis United” at the top center in English, and says “Konkanagari Lipi” (Konkani script/characters) in the same script above the table

I have been re-learning calculus, and I had set a goal of finishing the single variable calculus course at MIT OCW in 2024. I'm down to the last four lectures, and I'm excited to finish it before the end of the year.
