Bobblehead, Dual-Pendulum Toys Promote STEM Education to Fix Nation’s Problems

Fun, Bobblehead, dual pendulum novelties crafted from hockey pucks and fishing line both entertain people and illustrate the four fields of STEM education: science, technology, engineering, & math, now being promoted to solve our nations troubles. Employing familiar physical realities, such as push, pull, flex, eneract, and sense to introduce and symbolize STEM, dual pendulums entertain, enlighten, puzzle, & inspire people of almost all ages and persuasions, teenagers upThese newly developed, educational, dual pendulum novelties support the extensive effort and investment in STEM education by our government, president, legislators, and educators to solve our nation’s ills.Invoking mysterious gravity and mystical energy, dual pendulums exhibit the radiant, vibrant, communicant, eneractive nature and behavior of people and things, besides involving and symbolizing the four fields of STEM: science, technology, engineering, and math.The inventor claims that these astute learning objects can help to technically self-educate America in the hands-on, minds-on, inquiry way of educational standards. They tend to integrate the rather fragmented knowledge taught and memorized in school back into a unified whole.Scientist and teachers have employed similar simple, classical pendulums for centuries to informally introduce and teach STEM subjects.The dual-pendulum idea did not just happen. It grew out of the development of sophisticated sensing instruments and related pendulum calibrators for testing the behavior and monitoring the health of things.Dual pendulums connect two classic pendulums together by simply stringing hard rubber disks on an oversize, flexible plastic line. The disks slide on the line into position for conducting science experiments and inertially sensing changes in motion.With the two disks positioned apart at the lower knot, the lower disk and line form a visual, bobblehead, inertial motion sensor. Pull of the Earth (gravity) acts as a spring restraint. Like you, such sensors ordinarily flex to sense changes in motion, but not those of a coasting simple swing or pendulum (upper one), creating a mystery. Over a billion similar inertial motion sensors, also called accelerometers, now help trigger car air bags and stabilize camera images.Exercising a dual pendulum, a person experiences interacting objects transferring energy into action push and pull on one another to move, flex, vibrate, and sense per laws of nature, while properties of materials: mass (God particles), stiffness (elasticity), friction, and gravity, resist moving as they store energy in various ways. Similar things happen in other energy realms. Such eneraction, a new word, senses, animates, and powers our wonderful World.Operating a dual pendulum involves all four fields of STEM. Conducting classic science experiments requires engineering changes to a Plum’s structure to modify behavior by sliding disks on the line. Solving the mystery involves applying force-and-motion technology. Centrally adding mass confirms Newton’s famous law of motion, modeled mathematically as F=ma. Geometry helps explain why pendulums automatically swing, and why a shorter line increases the swinging rate.Testing a dual pendulum, students quickly learn that without a transfer of energy, nothing happens: objects don’t move, structures don’t flex, and sensors don’t sense, or change status.

And thanks to a legion of dedicated pendulum scientists, including Galileo and Newton, we now treasure a wealth of practical, useful knowledge and insight into how precious transfers of energy animate and power our magnificent World.
