His advances in physics, mathematics, astronomy, philosophy, alchemy & theology, have seen Sir Isaac Newton hailed as one of the most influential scientists that ever lived. The story about the apple hitting Newton s head & leading to the discovery & formulation of the Universal Law of Gravitation is known to most. The scientist is also credited for inventing the world s first reflecting telescope. This model, named Newton s Cradle after the man himself, was created by Newton to demonstrate a scientific discovery. The concept is straight forward: Pull up 1 ball of the Newton s Cradle, release it, & on impact, only 1 ball moves from that reaction. Pull up 2 balls of the Newton s Cradle, release & 2 balls will react. This simple, yet astonishing, result from the Cradle demonstrates the theory that every action has an equal & opposite reaction. The impact of the outer ball with the inner balls of Newton's Cradle displays the effect of energy being transferred through the stationary balls, because only the outer balls move in an equal reaction to each other. In summary, Newton s Cradle demonstrates that an object in motion continues in motion with the same speed & direction, unless acted upon by an unbalanced force. Set on a solid wood base, this supersized version of Newton s model, by Discovery Store, is larger than most cradles on the market & a popular choice in desk accessories & home ornaments. Visually superior to the stress ball, the model provides much needed tranquillity & stress relief during those busy work days. Watch it click away by your elbow, keeping hands busy & the mind stimulated. Buy for the Executive or as a gift for Dad, Gran Dad or the science fan, regardless of age.
