Cats are liquid — if they choose to be
Science marches on! A new study shows that cats can be liquid, if they choose to be.
Fardin noticed that these furry pets can adapt to the shape of the container they sit in—think of a cat in a vase—similarly to what fluids such as water do. So he used the principles of rheology, the branch of physics that deals with the deformation of matter, to calculate cats’ relaxation time, or the time it takes for them to take up the space of a vase or bathroom sink.
The conclusion? Cats can be either liquid or solid, depending on the circumstances, Fardin reported in the Rheology Bulletin in 2014…. A cat in a small box will behave like a fluid, filling up all the space, but a cat in a bathtub full of water will try to minimize its contact with it and behave very much like a solid.
Anyone who has ever owned a cat will be understand this research. It isn’t that cats can be liquid that is expected, it is that cats will do what they want. If they want to be liquid, no one is going to stop them.
Because of this ground-breaking research, the scientist has won this year’s Ig Nobel Physics Prize.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

They forgot to say that cat also exhibit displays of magnetivity and repulsion, sometimes at the same time!
I just know there’s a joke about Schrodinger in there somewhere…… ;-)
“Rheology,” I must admit, that is a new one for me.
Anecdotally; when I first encountered my current Cat, he was sleeping in cereal bowl.
Excuse while I digress briefly into quantum mechanics & Cats. (I’ve been waiting months to use this picture.)

Joe/Steve–
Ya beat me to it! Good stuff.
(I’ve been fumbling around for 20 minutes on this one, my browser isn’t playing well with reCAPTCHA today.)
Wayne, Love the photo! Also cat should have read as cats.
You can also pour cats just like a liquid.
Joe-
[“Also, cat should have read as cats.”]
That, is brilliant!
(seriously, been waiting months for a good cat + physics thread, to use that cat-carrier picture.)

good stuff.
If I flip my cat upside down, he immediately turns to Jell-O.

Had a cat once capable of reactionless acceleration. She was ambushing one of our hens in the backyard (no harm would come to either party – cat was doing it for fun) when the hen turned around while the cat was in mid leap. Hen jumped in the air and I swear the cat stopped in mid leap and went the other direction.
Mike-
“reactionless acceleration”
>Most excellent stuff!
So not only are they liquids, they’re non-newtonian liquids based on their behavior when contact with water is attempted.
Commodude-
…. very intriguing!

My link immediately above (if that’s even a ‘real’ Journal?!, found it on the Interweb) references 2 interesting papers on Cats & QM, but both appear to be behind a paywall.

Normally, I’d immediately attack such “crazy sounding research stuff,” but I like Cats and I get the abstract-concepts that underlie it all.
(In some alternate Universe, it’s maybe… Pavlov’s Cat & Schrodinger’s Dog?)
tangentially– “symmetry” in the field of Math concerns itself (in part) with determining the natural gate of animals as they walk or run, how spots & stripes manifest, patterns of sand dunes, etc..

Mitch S: In reading the second link you posted, I could not help think of numerous science fiction movies where aliens take over our brains. In this case, however, the aliens are cats!
