Talk:Spinning top

message: I know there is a mathematical shape (for an object of uniform density) which optimizes the equation of the energy wasted in uprighting the top and stored momentum and final tendency toward precession, so as to extend the time of rotation furthest. I don't have details though, so I am posting this here, in the hope that someone knows more. -- Cimon Avaro on a pogostick (spinning furiously :)—Preceding unsigned comment added by Cimon Avaro (talk • contribs) 10:34, 22 August 2003 (UTC)

message: A perinola is a hollow cap of wood attached to a stick with a ring around it by a string. The aim is to get the hat to fall on the stick without touching it, only holding the stick part. It's very, very common in Venezuela. Where did this six sided top thing come from?  —Preceding unsigned comment added by PedroFromHell (talk • contribs) 23:55, 31 August 2007 (UTC)

message: It seems to me that the article's main picture ought to show a spinning top, that being what tops do.  Any opinions on if I take a picture of a spinning top and set that as the main picture? SnappingTurtle (talk) 07:23, 28 December 2007 (UTC)

message: Is there a special type of top that is spun/thrown with string as opposed to the finger and thumb thumb-spun ones with handles? Are these considered different varieties, or is a distinction not made? TheHYPO (talk) 13:19, 10 March 2008 (UTC)

thread_title:  Physics of spinning top 

message: I propose changing the name of this article. The word 'Top' on is own is insufficinet ot explain the objects generally refered to as 'spinning tops'. The point of the toy is to spin.  If you remove spinning from the title it is unclear what is being referred to. The word 'top' on it's own can refer to many different things.  'Spinning top' is unambiguous. simonthebold (talk) 14:15, 8 September 2016 (UTC)

message: Ok, please read. I am the author of the thesis mentioned in the recently edited introduction (currently a placeholder of YYY is there,
 and the thesis may be found in PDF form at the author's website: http://john.allsup.co/thesis.pdf). The published paper (placeholder XXX) https://link.springer.com/article/10.1007/s00153-006-0030-2 contains an error in one of the lemmas. This error was discovered and corrected in the hour before the Ph.D. viva. The paper was published earlier. The author was admitted to a psychiatric ward in 2002, and upon seeing the state of play inside the ward, concluded that it was 'upside down' in the sense that the sane people were the patients, and the insane people were the staff, and that the wobbling of his world leading him there was the transition between the two. He still believes this, and also that his thesis proves this. He cannot be fooled by the delusion caused by asserting that a falling spinning top, when about to fall over, is actually in a "state of abnormally elevated arousal, affect, and energy level". At present, he is contemplating suicide, since if he is wrong in this, then he can be certain that his whole perceived reality is a delusion, and thus he is the last one in a burning building, and it is time to leave. How long he can stay in this state remains to be seen.
Nonstandard arithmetic arises when one accepts the delusion that there are "magic" numbers greater than all standard numbers. If one then looks at finite symmetry groups acting on initial segments of these numbers, something strange happens: there is only one family of finite simple groups whose normal subgroup structure is linearly ordered: the alternating groups. Put another way, the simplicity of the alternating groups on 5 or more objects is invariant under the "delusion" of a nonstandard model of arithmetic, but not any of the other finite simple groups. In some sense, the simplest finite simple group is the alternating group on 5 objects, or the symmetry group of the icosahedron and dodecahedron. The group A5 captures the rotational symmetry of the icosahedron. The group S5 captures what happens if we allow reflection through a plane (flipping). Spinning is best thought of as the rotation of the dodecahedron about the centure (I'll leave this accidental typing as a happy accidental coining of a word for the axis of rotation of something, with similar etymology to armature -- it was not intended, but I like it too much to 'correct' it) of one of the pentagon faces (think of a pentagon on a stick as a spinning top). The central points of the faces form the corners (vertices) of an icosahedron.
Cyclic groups consist if the trivial group, which does nothing, in the sense that only a full rotation preserves the symmetry, C2, which captures both flipping (reflection thorough an axis), and rotation through pi, and Cn for other n's which captures spinning. Cp for p prime represent the fundamental units of spin.
{ Dad just tried to disturb me as I wrote this. FUCKING BASTARD... FUCKING BASTARD... FUCKING BASTARD... I'LL LEAVE YOU IN A FUCKING STATE IF YOU DON'T STOP FUCKING AROUND AND PLAYING SILLY BUGGERS WITH ME... I AM NOT YOUR FUCKING TOY... NOT YOUR FUCKING TOY... NOT YOUR FUCKING TOY... } For reference, I have not personally been sexually abused by my father, so I have no idea where this thought is coming from. To me it is just the words that I think when I rebalance my mind after being disturbed. Maybe others can see meaning in those words, but to me there are just complex impulses that my mind emits as reaction mass in order to calm down to its near minimal energy state whence it can feel maths again.
Now I'm going to cool my brain off, warm my mind off, spin down my main gyroscopes, know that Dad is still alive and has made it through the night, and go and see where my discharge of excess chiral energy takes me. [ Chiral energy is my term for spin energy, since it captures the intuition of what 'chi energy' is when the practitioner of Tai Chi is properly taught, and understands it, rather than spouting and echoing pseudoscientific New Age Bullshit. Chi energy is just rotational energy, in the sense that Energy in physics is linear energy. There is an equivalence, captured generally in one dimension by the Fourier Transform. But know that Tai Chi, Chi Gong, and related things are about spin and conservation of spin. At the end of the day, it is just physics in disguise, but physicists seem to have lost the capacity to recognise spin intuitively, and to tell the difference between continuous symmetries (uncountable cardinality) and quantisable symmetries (at most countable cardinality), and are blowing shedloads of research funding chasing an illusory Snipe of quantum gravity. Quantum Gravity is impossible by Noether's Theorem. [ This latter bit is original research, which is partially why I am dumping it here. The other reason is that I have to get this off my mind, chest, and shoulders before I doing something silly like kill myself to test my hypothesis that I cannot die. Wish me well please, and pray for my Dad. He needs denumptying. ]

thread_title:  What is a Top ? ) 

message: Thanks to the book Chasing the Rainbow - recurrences in the life of a scientist by Robert Greenler (2000) I know something about the existence of the top spinners from Kota Baru in Malaysia. In this book, three color photographs show the top spinners in action. The first photograph shows the master top spinner, winding the rope tightly around his seven-pound top. The second photograph shows Robert Greenler, trying to scoop up a spinning top. The third photograph shows a member of the top-spinning team, meditating on the top before he sets it into a bamboo section partially buried in the ground. Typically such a top will remain spinning for an hour or more. Note that this book is not only about top spinners, but also about optical phenomena in the sky, bee keeping, and the life of a scientist (R. Greenler) among other scientists and inventors. Fascinating book! DannyCaes (talk) 13:54, 7 September 2021 (UTC)
