It takes time to change position of an object from one place to another place, and it takes time to change velocity to go, say, from zero to sixty miles for a car. Does it take time for acceleration to change from zero to a finite amount? Isaac Newton and all the physicists since Newton for the past three hundred years have not clearly answered this question. The Jumpulse Dance is an empirical proof that it does NOT take time to change acceleration from zero to a finite amount; if it does take time to change acceleration, the Jumpulse Dance would not be possible. The jumpulse applied to slide the feet must be a finite force in order to overcome the strong static friction force. The concept of jumpulse is initially invented as the solution of touch or collision without bounce and the solution of prolonged contact in sports.
The Jumpulse Dance takes the advantage of the sliding and takes into consideration of the artistic movements of past great dancers to choreograph a dance suitable for young and old. Its basic movement is the slide, which is a traits usually acquired by most experienced dancers after years of practice in non-sliding dances. The Jumpulse Dance has three No’s: No turning, No Jumping, and No Touching, and, thus, can be danced safely by the very young and the very old, say, from 8 to 80. It can have sliding backward, sideways, obliquely, and forward. During the slide, it allows the dancer to capture the micro-beats in the textured music of the Top 40 songs.
In the past three years, the Jumpulse Dance has help rekindle the dancing culture in nightclubs, starting with the clubs in the San Francisco Bay Area. It also help revived the two old dances, Running Man and Shufflin, whose movements are not as efficient as the linear sliding of the Jumpulse Dance. A recent video based on Shufflin even reached number one in Top 40 songs.
If you have the answer to the above problem, in any language, please email your answer to Prof. Chien Yi Lee

Prof. Chien Yi Lee disclosed for the first time in the "Meadowood Lecture" hosted by Doug King and demonstrated by Hugh Ching the physics of touch. Ching's law of touch is that acceleration, unlike velocity and position, can be changed instantaneously. Newton's law of inertia can land a man on the moon, and Ching's law is the reason that humans can touch. Touching is more important than landing a man on the moon.
There should be a world-wide debate by robotics researchers, physicists, mechanical engineers, and electrical engineers on whether touch (collision without bounce) is a problem, if it is a problem, has it been solved or not, and what is the solution to touch ?
The main applications of jumpulse are (1) Sports, (2) Spacecraft Docking, and (3) Automobile No-Bounce Shock Absorber, in addition to the long term application in Robotics.
