Also pre-order books from your favourite authors! Bookstores use total number of pre-orders as a metric for how many copies to order. The more pre-orders, the higher expectation for a run on purchases early after release, so will stock extra copies and promote prominently.
Will also note that if you like someone's books and want them to keep writing, supporting them by buying their books or ordering them from the library if buying isn't an option, and encouraging others to do the same, has a HUGE impact. Relatively small differences in sales numbers are make or break.

Happy #Fibonacci Day! Nov 23rd (11.23) begins the Fibonacci Sequence 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ... which is used in computing, stock trading, and architecture and design. Nature is full of Fibonacci patterns, from DNA to hurricanes, much more! www.smithsonianmag.com/science-natu...
The Fibonacci Sequence Is Everywhere—Even the Troubled Stock Market
The curious set of numbers shows up in nature and also in human activities.

Cecilia Payne-Gaposchkin ✨ figured out what stars are made of ✨ when she was just 25. 🔭🧪
Her PhD thesis basically established the Harvard astro department — at a time when Harvard didn't officially allow woman students.
I wrote this little profile to mark the 100th anniversary of her thesis:

Happy #PiDay! Pretty cool to have a blood moon total lunar eclipse overnight as we entered Pi Day 2025. Plenty of circles and spheres to celebrate on this last day of winter quarter classes. Cheers!

Having fun playing with my new wooden soma cube. Don't know why I didn't know this before, but it can be rearranged from 3x3x3 to 4x4x2 minus 5 contiguous unit cubes that form the shape of a pentomino (1 deep). 11 of the pentominos work (of the 12). Way cool! www.youtube.com/watch?v=dGSH...

15 +/- yrs at the bird site, past year at mastodon (@[email protected]). Checking BlueSky out! Bit concerned just another billionaire-run corporate SM, we'll see. To stay must support ALT descriptions, ability to edit posts, have interesting #mathematics content, and plenty of kind people.
