In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation. The rotation around a fixed axis of a three-dimensional body involves circular motion of its parts. The equations of motion describe the movement of the center of mass of a body.
on futuristic putters: Although there is a standard length for conventional putters (men's are 35 inches - 90cm, and women's are 33-34 inches - 84-86cm), don't be afraid of altering the length of your putter if you feel uncomfortable with it. Some putters are light and others are heavier.
I always recommend a standard height of 36 inches for kitchen islands as this is the most comfortable height to prep food at for the average person. If you are going to set chairs at the island consider a lower height of 30 inches, while 42 inches will work best if you are going to use a traditional height bar stool.
