It's largely in regards to sign conventions and a coordinate axis. Angular velocity has a (pseudo) vector direction associated with it (right hand rules and what not). When we're usually talking about spin we're usually just discussing magnitudes (rpms), and not in a vector sense. A backhand...

I would think the wobble sign would denote a positive or negative rotation axis no? i.e. clockwise as opposed to counter-clockwise precession. In that case the underside / topside of the disc would be exposed from a different side of the disc so to speak as viewed from the front while wobbling...

For sure. I guess where I was going with this is that it's hard to sometimes know what you don't know. A feeling of familiarity with a subject can sometimes be confused with having good knowledge. And nothing sheds that to light more than inquisitive students and peers, in the same way as...

Related, reminds me of the adage (paraphrased by a number of people), "if you ever want to learn something then teach it."

Is the range in the above the distance travelled by the disc (horizontal line length), or displacement from the thrower? The above is not necessarily in disagreement with Eric's simulations if they reduced the horizontal coordinate to line length (i.e. x,y-> s). If you view a disc thrown from...

For sure, I'm not trying to throw the baby out with the bath water so to speak. I think the ground action and it impacting spin was a particular interesting point I hadn't given real thought to before. Probably a fair bit of variability in there depending on surface conditions (i.e. friction...

Yeah, this is what stuck out to me in his explanation as well. He's trying to explain everything in purely rotation based mechanics, whereas the ground reaction will also want to steer the disc similar to someone on a skate. I'm also puzzled by his perception / intent when he says overstable...

Yeah, I don't throw that fast at all yet most throws I have quite an audible snap compared to most people. Just how you describe with the middle finger. Modified fan grip and long narrow fingers. When I started playing I used a power grip and it never really happened. Switched because my fingers...

Sure, not trying to be overly argumentative. I was intrigued by your original inquiry because there wasn't something inherent in the formulism that says no, which I think is interesting in itself. The field is filled with simple and innocuous phenomena with intuitive answers, but proving it is...

I don't disagree with the principle / spirit of what you're saying about free gyroscopic precession, but to be clear I'm talking about precession in the most generalized sense. That is to say any change in the orientation of the rotation axis. Where I'm driving this has to do with a torque on...

Sometimes the best way to approach these questions is to turn the question around. Or rather challenge the assumption. Why can't an object in the hand precess? Where does disc wobble come from if the disc can't precess while in the hand? The basic answer is that the disc creates / has angular...

I have the Yeti, which is just the Sasquatch in FP (Flex Performance) plastic. The weird wing shape still throws me off. I don't throw it often, but its understable characteristics means even at lower distances you can get some nice S shape movement out of it.

Yeah, no kidding. "Inertial mass increases tremendously" had my eyes rolling through the back of my head. Elasticity being lost to air... Vague language, big claims, a lot of hype before releasing their concrete media, questionable science, and a name to make it sound like one simple thing. Why...

I've continuously bagged the same Lucid Suspect for years now for the reasons you mentioned. Very reliable, and not as OS as its similarly numbered counterparts in other manufacturers I'm not sure of the exact story here, but I think these are back in production? Just a couple weeks ago a...

I would be cautious. The arm/wrist picture is incomplete. It's the direction the disc center of mass is going at release, and not the hand, which will dictate the tangent. Given that a disc breaks from back to front on a grip generally (the pivot), you have another arc on top of the arc you're...
