I had the thought that maybe the Australian airline had started a book side business, a la Stripe, but no, the airline is actually Quantas. Still seems like an imprint to follow.

  Launched by Thomas Lin, the founding editor of Quanta Magazine, in 
  partnership with Farrar, Straus and Giroux, Quanta Books is an editorially 
  independent subsidiary of the Simons Foundation, a nonprofit organization 
  dedicated to advancing the frontiers of research in mathematics and the basic 
  sciences. 

The Simons Foundation was started by Jim Simons of Renaissance Tech, someone who seemingly isnt actively trying to poison public discourse with his billions of dollars, which I respect. We need more Jim Simons types and less Bezos/Musk/Ellison-type narcissistic psychopaths.
