respect your passion for science...i borrowed the 'the Math book' from the library on seeing ur video on it...its a excellent book.and loved the book and maths...thanks....just wish it was around when I was in school and hated maths so much....
Now I know of one country during WWII wherein they simply couldn't be bothered with models, nor with paying the experimenter. You of course know to which one I refer.
Remember that episode of Mythbusters when they used a funnel and centrifugal force to force all those balls underwater? All you got to do is put a cover over the sink that has a hole in the center, get a fire hose spraying a nice votex down the funnel and out the sink drain and then send the cats swirling down the funnel and into the sink, I was really surprised how well this method worked for ping pong balls so I am optimistic about this method.
lol How many dead Schrödinger's cats that were victims of his experiment, can fit into Joanne sink, haha just kidding Schrödinger keeped saying it was only a thought experiment, we ha to believe him, but who knows about other physicists :(
The more interesting question would have been: Why do cats always have to sit in sinks, but I guess thats a matter of behavioural psychology. I never saw an explanation for that.
P.S. You can improve the process of evaluation by blending the cats in a mixer before measuring the amonut. This way, you can even determin the fractional digits. Ask Tom Dickson from Blendtec, he might provide you with equipment. Perhaps he can also make another episode of "Will it blend?" out of this, lol.
Stuffed cats won't work as models because they are much bigger than actual cat. Real cat's volume is smaller because of fur. If you have seen photos of wet cat - it's very-very slim.
I think the most precise way would be taking a blender to the cat, finding the liquid volume measure of him and then comparing that to the volume of the sink. But your way probably has fewer Research Ethics Board hurdles to jump thru...
You've done an amazing job of explaining and demonstrating the fundamental concepts that any young people who want to go into scientific research would want to know! Do you teach as well as do research?
Thank you. I think science is fascinating as a process and not just for the cool things we can do or discover. At this point I teach laboratory courses at University of Illinois (Dep't of BioE) and only do consulting or part time research to help colleagues who are engineers and not strong in cell biological techniques. I love teaching!
Rather than taking linear measurements for an irregular 3-dimensional object like a cat, you could get a lot closer value for actual volume by immersing the cat in a large vessel filled with water, collecting the overflow in another container, and measuring it to determine how much water the cat displaces.
No, I didn't see the annotation. Hmmm. If getting wet makes your cat unhappy, I suggest a simplifying assumption: that cats and dogs are of about the same overall density.
1. Weigh Golden Retriever. Submerse to determine volume. Calculate density.
2. Weigh cat and use density of Golden Retriever to calculate cat volume.
@TheHomeScientist Cat's don't like getting wet so probably the most accurate why to find the volume of a cat is to place it in a container, fill the container with gas and take the cat out. Then all you have to do is measure the volume of the gas.
Or, to simplify even more, determine experimentally if cats float. Presumably, like dogs and most people, they do float. That makes their overall density just under 1.0 g/mL. Weigh cat, assume 0.95 g/mL, and calculate volume.

Immerse cat in water, measure displaced volume and then calculate. Only works for liquified cats. Sorry Graucho

I'm allergic to cats, and my voice becomes a bit hoarse and raspy when I am around them. So you'll the notice the difference in my voice.

I mentioned that in an annotation, but maybe that didn't show up on your vid. Still, we are left with unhappy, wet cats...

Those are both good ideas to consider, and probably has as much error as measuring an irregular object.
