Isaac Newton, it is said in Country Parson had a cat in his chamber. To get a full access for this fluffy sweet creature to his chamber, Newton cut a hole in the bottom of his study door so that the puss could get in and out. He named the cat, Splitface 😦 (bad name for cat). By the time, the cat had kittens. So Newton cut a small hole in the door next to the bigger one.
When Dodgson meet cat, the Cheshire cat were created
Lewis Carroll a pen name of the mathematician Charles Lutwidge Dodgson had a cat, but he created one of the most memorable fictional cats: the Cheshire Cat, which slowly faded away until only its grin remained in his depiction in Alice’s Adventures in Wonderland. The Cheshire isn’t a breed of cat: it is an English county where cheese was (and still is) made. Possibly Carroll was referring to the British shorthair, a breed of cat that appeared on Cheshire Cheese labels.
When Arnold meet cat, the Map of Arnold’s cat were created
Vladimir Arnold aRussian mathematician, studied a chaotic map (another word for ‘function’ or ‘transformation’) from the torus to itself, using an image of cat. Defined by
where x and y lie between 0 (included) and 1 (excluded), and (mod 1) means that everything before the decimal point (the integer part) is ignored. So 17.443 (mod 1) 0.443, for instance. The dynamics of this map are chaotic (Cabinet, page 117); also, it ‘preserves area’, meaning that areas don’t change whe n it is applied. So it provided a simple model for more complicated area preserving maps arising naturally in mechanics.
What about the other mathematicians…..
Author Theoni Pappas wrote a math children’s book, The Adventures of Penrose the Mathematical Cat, presumably named after mathematical physicist Roger Penrose.
Loveby Rudy Rucker in his math books wrote, two mathematics graduate students prove a theorem characterising all dynamical systems in terms of objects from Dr Seuss’s The Cat in the Hat .
In his 1964 research text Abelian Categories, Peter Freyd included the index entry ‘kittygory’. The page concerned refers
to a ‘small category’. There’s a mathematician named Nicholas Katz does that count?
Um Felix Hausdorff?
What if the physicists meet cats…..???
Oh, No! Don’t say that! It can be so cruel ;(
Schrodinger’s cat doesn’t have a lot of choice, only a matter of live and death.
Even, physicist can think about any other crazy think such as double split experience with a kitten cannon.
It was measured since kittens are about 0.1m long, the slits should each be about that size, and, say, 2m apart (larger slits need to be farther apart, to keep the interference fringes from overlapping). So d = 2m. Finally, the interference fringes on the screen to be several times farther apart than the kittens are large, otherwise you won’t be able to tell which kitten impact corresponds to which fringe. Say 1m apart, give or take.After passing through (both) of the double slits the cats will have to fly through about 330 quadrillion light years of purfectly empty space, before impacting the projection screen (on their feet, naturally).
Fortunately, in order to get reasonable results from the experiment, it should be repeated at least 1036 times (about one hundred identical-to-the-last-atom-cats per fringe). As a quick aside; that’s too many cats. They better use laser! But I am afraid if they wanna know the effect of color of the cats, or whether they are short hairs or longhairs to the experiment result ;(
And what gonna happen if you meet a cat…….miauwwww
