Hey look, it's Friday. Let's see what I threw together this week.

Saturday Review cover from 1974 - s-l1600
Lord Trevelyan's first, but surely not last, appearance in the pages of Wolmania

David Cassel of The New Stack writes about what some leading scientific minds, in 1974, predicted for 2024. On the one hand, they kinda nailed the future of computing (and the internet). On the other hand, they thought we'd be living on Mars. Oddly enough, no one seems to have predicted Uncrustables, vaping, or Godzilla x Kong: The New Empire.

Item 2: a list

Chart showing the 5 Circles of Latitude (unranked)

Circles of Latitude, ranked:

  1. Arctic Circle
  2. Tropic of Cancer
  3. Tropic of Capricorn
  4. Equator
  5. Antarctic Circle

Item 3: a media recommendation

Crosby, Stills, & Nash - Teach Your Children (a different version)

Item 4: word of the week


Seek refuge, lest my mighty battle-lizard - caparisoned in the gilded scales of her ancestors - rend your limbs from your torso. She's in a particularly bad mood today.

Item 5: a photograph

The arms of a grand design spiral galaxy 60,000 light-years across are unwound in this digital transformation of the magnificent 2005 Hubble Space Telescope portrait of M51. In fact, M51 is one of the original spiral nebulae, its winding arms described by a mathematical curve known as a logarithmic spiral, a spiral whose separation grows in a geometric way with increasing distance from the center. Applying logarithms to shift the pixel coordinates in the Hubble image relative to the center of M51 maps the galaxy's spiral arms into diagonal straight lines. The transformed image dramatically shows the arms themselves are traced by star formation, lined with pinkish starforming regions and young blue star clusters. Companion galaxy NGC 5195 (top) seems to alter the track of the arm in front of it though, and itself remains relatively unaffected by this unwinding of M51. Also known as the spira mirabilis, logarithmic spirals can be found in nature on all scales. For example, logarithmic spirals can also describe hurricanes, the tracks of subatomic particles in a bubble chamber and, of course, cauliflower.

See ya!

Thanks for reading. Au revoir.
