The Coriolis Force and the Rattleback
The Coriolis Force and the Rattleback Frederick David Tombe, Belfast, Northern Ireland, United Kingdom, [email protected] 17th December 2010 Abstract. The rattleback (Celtic Stone) is the most mysterious phenomenon in classical mechanics. It reverses its angular momentum by inducing a Coriolis pressure from the dense background sea of rotating electron-positron dipoles which is the medium for the propagation of light. [1] Magnets and Rattlebacks I. Magnets and rattlebacks share in common the fact that they involve a mutual alignment of the spin moments of their constituent atoms and molecules. They differ however in that rattlebacks involve a rotation on the large scale in order to bring this alignment about. In magnetic materials, the induced spin alignment results in a linear force, whereas in rattlebacks, the induced spin alignment results in a reversal torque which opposes the initial rotation. Another important difference is that rattlebacks are generally made of materials which are not as dense as magnetic materials. [2] Gravity and Friction II. Gravity acts vertically downwards and so the reversal torque in a rattleback cannot be sourced in gravity. Sliding friction is involved in that it dissipates the entire motion, but sliding friction by its nature is not something that could cause a reversal torque. Static friction is necessary in order to enable the rocking stage of the rattleback’s cycle. Without static friction, a rattleback will not work. However, static friction by its nature is not something that could actually go as far as to cause a reversal torque. 1 Forging a Torque by Mathematical Manipulation III. -
HISTORY and STAGE METHOD of JUGGLING with HULA HOOPS Oleksandra Sobolieva Kyiv Municipal Academy of Circus and Variety Arts, Kiev, Ukraine
INNOVATIVE SOLUTIONS IN MODERN SCIENCE № 2(11), 2017 UDC 792 (792.7) HISTORY AND STAGE METHOD OF JUGGLING WITH HULA HOOPS Oleksandra Sobolieva Kyiv Municipal Academy of Circus and Variety Arts, Kiev, Ukraine Research the methods of teaching juggling tricks by the big and small hula hoops, due to rising demand for hula hoops in recent years. Hula hoops acquire much popularity both abroad and in Ukraine, and are used not only in school, gymnastics and emotional pleasure, but also in a circus and juggling sports. Also highlights the main directions in the juggling with their features and how the juggling acts itself directly on human health. Also will be examined where this fascinating art form came to us, how it developed, and what kinds acquired in the present. Keywords: hula hoops, juggling, "track", stage technique, white substance, "helicopter". Problem definition and analysis of researches. Today juggling reached incredible development. There is no country where people would not be interested in juggling. There are a lot of conventions and juggling competitions, where people come from all over the world and share experiences with each other. But it should be noted, that there aren’t so much professional juggling schools. And if we talk about juggling by hula hoops, we can admit that there aren’t so much real experts in this field. Peter Bon, Tony Buzan in collaboration with Michael J. Gelb, Luke Burridge, Alexander Kiss, Paul Koshel and many others have written about all kinds of juggling, but left unattended hula hoops juggling. That is why in this article will be examples of author’s tricks with large and small hula hoops with a detailed description. -

Rattlebacks for the Rest of Us Simon Jonesa) Department of Mechanical Engineering, Rose-Hulman Institute of Technology, Terre Haute, Indiana 47803 Hugh E
Rattlebacks for the rest of us Simon Jonesa) Department of Mechanical Engineering, Rose-Hulman Institute of Technology, Terre Haute, Indiana 47803 Hugh E. M. Hunt Engineering Dynamics and Vibration, University of Cambridge, Cambridge CB21PZ, United Kingdom (Received 21 November 2018; accepted 18 June 2019) Rattlebacks are semi-ellipsoidal tops that have a preferred direction of spin (i.e., a spin-bias). If spun in one direction, the rattleback will exhibit seemingly stable rotary motion. If spun in the other direction, the rattleback will being to wobble and subsequently reverse its spin direction. This behavior is often counter-intuitive for physics and engineering students when they first encounter a rattleback, because it appears to oppose the laws of conservation of momenta, thus this simple toy can be a motivator for further study. This paper develops an accurate dynamic model of a rattleback, in a manner accessible to undergraduate physics and engineering students, using concepts from introductory dynamics, calculus, and numerical methods classes. Starting with a simpler, 2D planar rocking semi-ellipse example, we discuss all necessary steps in detail, including computing the mass moment of inertia tensor, choice of reference frame, conservation of momenta equations, application of kinematic constraints, and accounting for slip via a Coulomb friction model. Basic numerical techniques like numerical derivatives and time-stepping algorithms are employed to predict the temporal response of the system. We also present a simple and intuitive explanation for the mechanism causing the spin-bias of the rattleback. It requires no equations and only a basic understanding of particle dynamics, and thus can be used to explain the intriguing rattleback behavior to students at any level of expertise. -
An Interactive Design System of Free-Formed Bamboo-Copters
Pacific Graphics 2016 Volume 35 (2016), Number 7 E. Grinspun, B. Bickel, and Y. Dobashi (Guest Editors) An Interactive Design System of Free-Formed Bamboo-Copters Morihiro Nakamura, Yuki Koyama, Daisuke Sakamoto and Takeo Igarashi The University of Tokyo Figure 1: Using our interactive design system, users can design free-formed, even asymmetric, bamboo-copters that can be easily fabricated and can successfully fly. Abstract We present an interactive design system for designing free-formed bamboo-copters, where novices can easily design free- formed, even asymmetric bamboo-copters that successfully fly. The designed bamboo-copters can be fabricated using digital fabrication equipment, such as a laser cutter. Our system provides two useful functions for facilitating this design activity. First, it visualizes a simulated flight trajectory of the current bamboo-copter design, which is updated in real time during the user’s editing. Second, it provides an optimization function that automatically tweaks the current bamboo-copter design such that the spin quality—how stably it spins—and the flight quality—how high and long it flies—are enhanced. To enable these functions, we present non-trivial extensions over existing techniques for designing free-formed model airplanes [UKSI14], including a wing discretization method tailored to free-formed bamboo-copters and an optimization scheme for achieving stable bamboo- copters considering both spin and flight qualities.

Creating a Board Game to Influence Student Retention and Success
ENROLLED: CREATING A BOARD GAME TO INFLUENCE STUDENT RETENTION AND SUCCESS by Andrew H. Peterson This dissertation is submitted in partial fulfillment of the requirements for the degree of Doctor of Education Ferris State University November 2018 © 2019 Andrew H. Peterson All Rights Reserved ENROLLED: CREATING A BOARD GAME TO INFLUENCE STUDENT RETENTION AND SUCCESS by Andrew H. Peterson Has been approved November 2018 APPROVED: Jonathan Truitt, PhD Committee Chair David Simkins, PhD Committee Member Paul Wright, PhD Committee Member Dissertation Committee ACCEPTED: Roberta C. Teahen, PhD, Director Community College Leadership Program ABSTRACT This dissertation documents the justification, creation, and refinement of a traditional board game to be used in first-year experience (freshman seminar) courses. The board game enRolled allows students to play college in a guided classroom environment. The game creates a low-stakes environment for students to be able to fail at college without risking time and money. Further, it is designed to give students a relatable topic to debate. By having a common experience, students can distance themselves from what their expectations of college are and deliberate on the tangible game they have played. The discussions that stem from this play and the modification of the game elements are designed to help the students take ownership over the experience. Having a game experience to discuss allows a student to objectively analyze their player’s path through the academic setting and debate realistic and perceived unrealistic challenges. Through these discussions, it is possible for students to engage with content while having little to no firsthand knowledge. It is the hope of this author that the creation of enRolled leads to a more engaging curriculum in first-year experience courses. -
