They did a lot of maths and showed that the direction that fixed angle solar panels should be pointed to maximize energy is slightly eastward from the standard south if afternoons are cloudier than mornings averaged over the year.

Domestic cats (Felis catus) prefer freely available food over food that requires effort, unlike pigs, giraffes, rats, manned wolves, grizzly bears, pigeons, jungle fowl, chickens, macaques, chimpanzees and humans.

Researchers — Mikel M. Delgado , Brandon Sang Gyu Han , Melissa J. Bain researched the behavior of 17 neutered indoor domestic cats, presenting them a food puzzle and a feed tray for 30 minutes 4 times a day.

More cats ate from the free feed tray more than the puzzle (16 out of 17) and more cats approached the feed tray before the food puzzle.
